2509 Living Donor Nephrectomies, Morbidity and Mortality, Including the UK Introduction of Laparoscopic Donor Surgery

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 11 2007
V. G. Hadjianastassiou
The worldwide expansion of laparoscopic, at the expense of open, donor nephrectomy (DN) has been driven on the basis of faster convalescence for the donor. However, concerns have been expressed over the safety of the laparoscopic procedure. The UK Transplant National Registry collecting mandatory information on all living kidney donations in the country was analyzed for donations between November 2000 (start of living donor follow-up data reporting) to June 2006 to assess the safety of living DN, after the recent introduction of the laparoscopic procedure in the United Kingdom. Twenty-four transplant units reported data on 2509 donors (601 laparoscopic, 1800 open and 108 [4.3%] unspecified); 46.5% male; mean donor age: 46 years. There was one death 3 months postdischarge and a further five deaths beyond 1 year postdischarge. The mean length of stay was 1.5 days less for the laparoscopic procedure (p < 0.001). The risk of major morbidity for all donors was 4.9% (laparoscopic = 4.5%, open = 5.1%, p = 0.549). The overall rate of any morbidity was 14.3% (laparoscopic = 10.3%, open = 15.7%, p = 0.001). Living donation has remained a safe procedure in the UK during the learning curve of introduction of the laparoscopic procedure. The latter offers measurable advantages to the donor in terms of reduced length of stay and morbidity. [source]

47 Comparison between open and laparoscopic live donor nephrectomy

BJU INTERNATIONAL, Issue 2006
S. KALOUCAVA
Introduction:, Renal replacement therapy is the best management for end stage renal failure. Laparoscopic Donor Nephrectomy (LDN), which is considered safe and effective, began in our unit in July 2003 with an average transplant rate of 12 per year. The aim of this study is to compare the donor morbidity, recovery and costs between Open Donor Nephrectomy (ODN) and LDN. Method:, A retrospective consecutive series of all Donor Nephrectomies since June 2002 were included in this study. Operative details, postoperative donor recovery, donor and recipients renal functions were reviewed. The total costs will also be calculated and compared. Results:, There were 18 LDN and 18 ODN (Total 36 cases) included in this series and equal number of male to female cases. Average operative time for ODN was 2.07 h and LDN was 3.36 h. There was no intra-operative conversion from LDN to ODN and no peri-operative morbidities in either group. The transplanted renal vessel lengths were also compared which showed an average artery length of 40 mm and vein length of 50 mm in the LDN group versus an average of 35 mm artery length and 30 mm vein length in the ODN group. The outcome of the recipient's renal function was not affected whether the donor had OPD or LDN. Average length of hospital stay was 6 days in ODN and 4.5 days in LDN. Costs data to follow. Conclusion:, Laparoscopic Donor Nephrectomy (LDN) is safe and effective in a smaller renal transplant unit. [source]

Laparoscopic Live Donor Nephrectomy with Vaginal Extraction: Initial Report

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2010
M. E. Allaf
The recent decrease in the total number of living kidney transplants coupled with the increase in the number of candidates on the waiting list underscores the importance of eliminating barriers to living kidney donation. We report what we believe to be the first pure right-sided laparoscopic live donor nephrectomy with extraction of the kidney through the vagina. The warm ischemia time was 3 min and the renal vessels and ureter of the procured kidney were of adequate length for routine transplantation. The donor did not receive any postoperative parenteral narcotic analgesia, was discharged home within 24 h and was back to normal activity in 14 days. The kidney functioned well with no complications or infections. Laparoscopic live donor nephrectomy with vaginal extraction may be a viable alternative to open and standard laparoscopic approaches. Potential advantages include reduced postoperative pain, shorter hospital stay and convalescence and a more desirable cosmetic result. These possible, but yet unproven, advantages may encourage more individuals to consider live donation. [source]

Chylous Ascites Requiring Surgical Intervention after Donor Nephrectomy: Case Series and Single Center Experience

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 1 2010
J. Aerts
Chylous ascites as a result of laparoscopic donor nephrectomy (LDN) is a rare complication that carries significant morbidity, including severe protein-calorie malnutrition and an associated immunocompromised state. We report a patient who underwent hand-assisted left LDN and subsequently developed chylous ascites. He failed conservative therapy including low-fat diet with medium-chain triglycerides (LFD/MCT) and oral protein supplementation as well as strict NPO status with intravenous (IV) total parenteral nutrition (TPN) and subcutaneous (SQ) somatostatin analogue administration. Laparoscopic re-exploration and intracorporeal suture ligation and clipping of leaking lymph channels successfully sealed the chyle leak. We review the literature to date including diagnosis, incidence, management options, psychosocial aspects and clinical outcomes of chylous ascites after LDN. [source]

The Detrimental Effect of Poor Early Graft Function After Laparoscopic Live Donor Nephrectomy on Graft Outcomes

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 2 2009
J. M. Nogueira
We undertook this study to assess the rate of poor early graft function (EGF) after laparoscopic live donor nephrectomy (lapNx) and to determine whether poor EGF is associated with diminished long-term graft survival. The study population consisted of 946 consecutive lapNx donors/recipient pairs at our center. Poor EGF was defined as receiving hemodialysis on postoperative day (POD) 1 through POD 7 (delayed graft function [DGF]) or serum creatinine , 3.0 mg/dL at POD 5 without need for hemodialysis (slow graft function [SGF]). The incidence of poor EGF was 16.3% (DGF 5.8%, SGF 10.5%), and it was stable in chronologic tertiles. Poor EGF was independently associated with worse death-censored graft survival (adjusted hazard ratio (HR) 2.15, 95% confidence interval (CI) 1.34,3.47, p = 0.001), worse overall graft survival (HR 1.62, 95% CI 1.10,2.37, p = 0.014), worse acute rejection-free survival (HR 2.75, 95% CI 1.92,3.94, p < 0.001) and worse 1-year renal function (p = 0.002). Even SGF independently predicted worse renal allograft survival (HR 2.54, 95% CI 1.44,4.44, p = 0.001). Risk factors for poor DGF included advanced donor age, high recipient BMI, sirolimus use and prolonged warm ischemia time. In conclusion, poor EGF following lapNx has a deleterious effect on long-term graft function and survival. [source]

Laparoscopic Live Donor Nephrectomy: A Risk Factor for Delayed Function and Rejection in Pediatric Kidney Recipients?

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 1 2005
A UNOS Analysis
The impact of laparoscopic (vs. open) donor nephrectomy on early graft function and survival in pediatric kidney recipients (,18 years) is unknown. We studied 995 pediatric live donor txs reported to UNOS from January 2000 to June 2002, in two recipient age groups: 0,5 years (n = 212, 44% laparoscopic donors [LapD]) and 6,18 years (n = 783, 50% LapD). Delayed graft function (DGF) rates were higher for LapD versus open donor (OpD) txs (0,5 years, 12.8% vs. 2.5%[p = 0.004]; 6,18 years, 5.9% vs. 2.8%[p = 0.03]). Acute rejection incidence for LapD versus OpD txs was higher at 6 months for recipients 0,5 years (18.6% vs. 5.9%, p = 0.01) and 6,18 years (22.5% vs. 15.6%, p = 0.03), and 1 year for recipients 0,5 years (24.3% vs. 7.9%, p = 0.004). In multivariate analyses, significant independent risk factors for rejection at 6 months and 1 year were recipient age 6,18 years, pretx dialysis, LapD nephrectomy and DGF. Graft survival was similar for LapD versus OpD txs. In this retrospective UNOS database analysis, LapD procurement was associated with increased DGF and an independent risk factor for rejection during the first year, particularly for recipients 0,5-years old. Future investigations must confirm these findings and identify strategies to optimize procurement and pediatric recipient outcome. [source]

Laparoscopic (vs. Open) Live Donor Nephrectomy: A UNOS Database Analysis of Early Graft Function and Survival

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2003
Christoph Troppmann
The impact of laparoscopic (lap) live donor nephrectomy on early graft function and survival remains controversial. We compared 2734 kidney transplants (tx) from lap donors and 2576 tx from open donors reported to the U.S. United Network for Organ Sharing from 11/1999 to 12/2000. Early function quality (>40 mL urine and/or serum creatinine [creat] decline >25% during the first 24 h post-tx) and delayed function incidence were similar for both groups. Significantly more lap (vs. open) txs, however, had discharge creats greater than 1.4 mg/dL (49.2% vs. 44.9%, p = 0.002) and 2.0 mg/dL (21.8% vs. 19.5%, p = 0.04). But all later creats, early and late rejection, as well as graft survival at 1 year (94.4%, lap tx vs. 94.1%, open tx) were similar for lap and open recipients. Our data suggests that lap nephrectomy is associated with slower early graft function. Rejection rates and short-term graft survival, however, were similar for lap and open graft recipients. Further prospective studies with longer follow up are necessary to assess the potential impact of the laparoscopic procurement mode on early graft function and long-term outcome. [source]

Concomitant Surgery With Laparoscopic Live Donor Nephrectomy

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 2 2003
Ernesto P. Molmenti
Routine live donor evaluations reveal unexpected silent pathologies. Herein, we describe our experience treating such pathologies at the time of laparoscopic donor nephrectomy. We have not encountered any previous reports of such an approach. We prospectively collected data on 321 donors. Concomitant surgeries at the time of procurement included two laparoscopic adrenalectomies, one colposuspension, one laparoscopic cholecystectomy, and one liver biopsy. Mean operative time was 321 min (range 230,380), with a mean blood loss of 280 mL (range 150,500). No blood transfusions were required. The left kidney was procured in four cases. The right kidney was obtained on one occasion. Mean hospital stay was 3 days (median 3, range 2,4). No short- or long-term complications have been identified. Mean follow-up time was 2.63 years (median 2.76, range 2.23,2.99). Four of the five kidney recipients were first-time transplants who had not yet started dialysis. Simultaneous surgical interventions at the time of laparoscopic live kidney donation are safe and can be undertaken in selected cases. This practice is beneficial to both the donor and the recipient, and is likely to become more commonplace with changing practice patterns involving donor evaluation and management. [source]

47 Comparison between open and laparoscopic live donor nephrectomy

Optimizing open live-donor nephrectomy , long-term donor outcome

CLINICAL TRANSPLANTATION, Issue 3 2004
M Schostak
Abstract:, Introduction:, The technique of laparoscopic or retroperitoneoscopic donor nephrectomy has been increasingly propagated in recent years. The central advantage is supposed to be a reduction of perioperative discomfort. However, there have not been many reports describing the subjective feeling associated with an open donor nephrectomy, particularly with respect to the pain level in the perioperative and long-term course. This retrospective study examines the perioperative pain and morbidity and long-term outcome of living kidney donors from 35 yr of experience at the University Hospital Benjamin Franklin of the Free University of Berlin. Methods:, A total of 102 living kidney donors were asked to fill out a questionnaire. Five epidemiological questions were posed and the rest dealt mainly with lasting subjective and objective surgical impairments. There were also questions relating to the perioperative pain level (VAS/NAS-Score). In addition, basic information was obtained regarding the donor's current health status (physical examination, serum creatinine; sometimes also ultrasound, protein IU, blood pressure), and/or examinations were performed. Results:, The mean age at the time of donation was 45.5 and 55% were women. Donor nephrectomies were left-sided in 78 cases and right-sided in 24. There was a total complication rate of 53%, but serious complications only occurred in two cases (1.9%). A total of 53 donors could be reached. Although 41.5% felt they had a lasting impairment, somatic sequelae like respiratory, abdominal or scar problems were rare, affecting a maximum of only four patients in each case. Fifteen patients reported neurological problems such as sensory disturbances. The mean serum creatinine was 89.9 ,mol/L in female and 114.2 ,mol/L in male donors. Microalbuminuria was found in 22.6% of the donors, hypertension in 35.8%. Persistent pain was reported by 20.7%, its occurrence being permanent in two of the donors and very frequent in one. All the others rarely have pain. The median perioperative VAS/NAS score was 8 on the first day after surgery, 5 after 1 wk and 1 after 1 month. The analgesia was rated as good or very good by 71%. Everyday life was managed as well as before surgery after 2,4 wk by the highest percentage (42%) of patients, but working capacity was only regained after 1,3 months by a comparable percentage (44%). Forty-six percent had a very good and 33% a good feeling after the kidney donation. The relationship to the recipient had intensified in most cases. Ninety-one percent would again decide in favor of a donation. Conclusion:, Donor nephrectomy in an open technique is a safe and reliable procedure with low morbidity. After a median post-operative period of 7 yr, however, 42% of the donors still report general impairment due to the intervention, although concrete somatic problems were only detected in a few cases. Nearly all these patients underwent surgery in a full flank position. Wound-healing impairments were also significantly more frequent with this surgical technique. This positioning should thus be avoided. The post-operative pain level was relatively high, but a marked improvement was achieved in the course of the observation period by optimizing analgesic management. [source]

Complete robotic-assistance during laparoscopic living donor nephrectomies: An evaluation of 38 procedures at a single site

INTERNATIONAL JOURNAL OF UROLOGY, Issue 11 2007
Jacques Hubert
Objective: To evaluate our initial experience with entirely robot-assisted laparoscopic live donor (RALD) nephrectomies. Methods: From January 2002 to April 2006, we carried out 38 RALD nephrectomies at our institution, using four ports (three for the robotic arms and one for the assistant). The collateral veins were ligated, and the renal arteries and veins clipped, after completion of ureteral and renal dissection. The kidney was removed via a suprapubic Pfannenstiel incision. A complementary running suture was carried out on the arterial stump to secure the hemostasis. Results: Mean donor age was 43 years. All nephrectomies were carried out entirely laparoscopically, without complications and with minimal blood loss. Mean surgery time was 181 min. Average warm ischemia and cold ischemia times were 5.84 min and 180 min, respectively. Average donor hospital stay was 5.5 days. None of the transplant recipients had delayed graft function. Conclusions: Robot-assisted laparoscopic live donor nephrectomy can be safely carried out. Robotics enhances the laparoscopist's skills, enables the surgeon to dissect meticulously and to prevent problematic bleeding more easily. Donor morbidity and hospitalization are reduced by the laparoscopic approach and the use of robotics allows the surgeon to work under better ergonomic conditions. [source]

A systematic review of hand-assisted laparoscopic live donor nephrectomy

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2004
P. Dasgupta
Summary We provide a systematic review of hand-assisted laparoscopic live donor nephrectomy (HALDN), a relatively new procedure. Medline search of HALDN between 1995 and 2002 was conducted. Published studies were scored by two independent assessors using a modified form of 11 generic questions. All questions required one of three responses: 0 , criterion not reported, 1 , criterion reported but inadequate, 2 , criterion reported and adequate. The studies were placed according to their scoRes in category A (score 20,22), category B (17,19) and category C (16 or less). Higher scores indicate better quality of studies. Where possible, statistical analysis of comparative data was performed. Most reports of HALDN are expert series, some comparative and a few prospective. There was good correlation between the assessors (r = 0.91), and of the seven published series on HALDN, two fell into category B and five into category C. At present, there is only one published randomised-controlled trial of HALDN vs. open donor nephrectomy; this is the only such trial in laparoscopic urology. HALDN allows kidneys to be harvested with short operating and warm ischaemia times and fewer ureteric complications. HALDN is a relatively new and effective technique, designed to make kidney donation more attractive and minimally invasive without affecting recipient outcomes. More prospective data of this technique is needed, and wide variation in reported outcome parameters need to be standardised to allow meaningful comparison. [source]

Urological complications in 980 consecutive patients with renal transplantation

INTERNATIONAL JOURNAL OF UROLOGY, Issue 10 2006
HAMID R DAVARI
Aim: To present the urological complications of renal transplantations performed in the last 14 years at one center and to briefly explain a modified method of Lich,Gregoir ureteroneocystostomy. Methods: The data of 980 patients receiving kidney transplants at the authors' institution from April 1991 to February 2004 were reviewed in a retrospective prospective study. In particular, surgical techniques and urological complications were noted. Results: A total of 980 patients had received kidney transplantation. Extravesical ureteroneocystostomy (Lich,Gregoir method) was used in the first 480 patients (group A). In the subsequent 500 patients, the authors' modified method of extravesical ureteroneocystostomy, using single layer anastomosis and small feeding tubes as stent, was used (group B). Overall urological complication rate was 2.8% (28 patients), including leakage (13 patients, 1.3%), stenosis (seven, 0.7%), obstruction (one, 0.1%), distal ureter necrosis (four, 0.4%), pelvocalyceal fistula (two, 0.2%) and implantation of ureter into the peritoneum (one, 0.1%). Urological complications were significantly more common in group A compared to group B (16, 3.3% and 9, 1.8%, respectively; P < 0.05). Conclusions: Preserving the adventitia, fat and blood supply of the ureter by delicate dissection of the ureter during donor nephrectomy, short ureters, and fixation of the adventitia, fat and blood supply of the ureter to the bladder wall, to prevent kinking or twisting, are important factors in decreasing urological complications. Additionally, the authors' method of ureteroneocystostomy is also effective in decreasing the incidence of ureteric complications. [source]

Hand-assisted laparoscopic and open living donor nephrectomy in Korea

INTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2005
JA HYEON KU
Abstract Background: We compared the results of hand-assisted laparoscopic living donor nephrectomy (LLDN) and conventional open living donor nephrectomy (OLDN). Methods: The clinical data on 49 hand-assisted LLDN and 21 OLDN on the left side performed at two institutions in Korea from January 2001 to February 2003 were reviewed. Demographic data of donors and recipients were similar in the two groups. Results: There was one conversion to an open procedure due to bleeding in the LLDN group. The median operation times (180 min in LLDN versus 170 min in OLDN) and warm ischemic times (2.5 min in LLDN versus 2.0 min in OLDN) in the two groups were similar. The estimated mean blood loss, duration of hospital stay and complication rate was also similar in the two groups. The LLDN group reported less pain (visual analog scale) postoperatively (4.1 versus 5.3), but this was not significant (P = 0.058). The time to oral intake in the LLDN group was significantly longer by an average of 1 day (P = 0.001). Return to work was sooner in the LLDN group (4.0 weeks versus 6.0 weeks; P = 0.026). The recipient graft function was equivalent between the two groups. Hand-assisted LLDN appears to be a safe and effective alternative to OLDN. Conclusion: Our findings suggest that this technique may give the ability provide grafts of similar quality to OLDN, while extending to the donors the advantages of a traditional LLDN procedure.

Conservative management of an extensive renal graft subcapsular hematoma arising during living donor nephrectomy.

JOURNAL OF CLINICAL ULTRASOUND, Issue 3 2010
Role of Doppler sonographic posttransplant follow-up
Abstract We report a case of subcapsular hematoma (SH) of a kidney graft arising during minimal-incision living-donor nephrectomy. SH covered at least two-thirds of the cortical surface. Capsulotomy was not done because it was deemed too risky. In the immediate postoperative period, a rapid deterioration of graft function was observed associated with Doppler sonographic evidence of graft compression. However, in the following days, spontaneous resolution of SH and progressive improvement of Doppler findings was observed, which preceded full recovery of graft function. Conservative management seemed a valid approach of this complication in this case where Doppler sonography proved essential for the follow-up. © 2009 Wiley Periodicals, Inc.

Melatonin protects kidney grafts from ischemia/reperfusion injury through inhibition of NF-kB and apoptosis after experimental kidney transplantation

JOURNAL OF PINEAL RESEARCH, Issue 4 2009
Zhanqing Li
Abstract:, Free radicals are involved in pathophysiology of ischemia/reperfusion injury (IRI). Melatonin is a potent scavenger of reactive oxygen and nitrogen species. Thus, this study was designed to elucidate its effects in a model of rat kidney transplantation. Twenty Lewis rats were randomly divided into 2 groups (n = 10 animals each). Melatonin (50 mg/kg BW) dissolved in 5 mL milk was given to one group via gavage 2 hr before left donor nephrectomy. Controls were given the same volume of milk only. Kidney grafts were then transplanted into bilaterally nephrectomized syngeneic recipients after 24 hr of cold storage in Histidine,Tryptophan,Ketoglutarate solution. Both graft function and injury were assessed after transplantation through serum levels of blood urea nitrogen (BUN), creatinine, transaminases, and lactate dehydrogenase (LDH). Biopsies were taken to evaluate tubular damage, the enzymatic activity of superoxide dismutase (SOD) and lipid hydroperoxide (LPO), and the expression of NF-kBp65, inducible nitric oxide synthase (iNOS), caspase-3 as indices of oxidative stress, necrosis, and apoptosis, respectively. Melatonin improved survival (P < 0.01) while decreasing BUN, creatinine, transaminases, and LDH values up to 39,71% (P < 0.05). Melatonin significantly reduced the histological index for tubular damage, induced tissue enzymatic activity of SOD while reducing LPO. At the same time, melatonin down-regulated the expression of NF-kBp65, iNOS, and caspase-3. In conclusion, donor preconditioning with melatonin protected kidney donor grafts from IRI-induced renal dysfunction and tubular injury most likely through its anti-oxidative, anti-apoptotic and NF-kB inhibitory capacity.

Effect of donor pneumoperitoneum on early allograft perfusion following renal transplantation in pediatric patients: An intraoperative Doppler ultrasound study

PEDIATRIC TRANSPLANTATION, Issue 5 2008
S. Dave
Abstract:, Decreased perfusion and trauma during laparoscopic harvesting are proposed causative factors for DGF and rejection in children following renal transplantation with laparoscopic donor nephrectomy (LDN) allograft. We performed a retrospective review of 11 children who underwent LDN transplant and 11 preceding patients who underwent ODN transplant. Intraoperative DUS findings, creatinine values and clearance, time to nadir creatinine and AR episodes were compared. There were no significant differences in the BMI, vascular anatomy, side of nephrectomy, or warm ischemia time in the two groups. Mean follow-up duration was 11.4 and 30.4 months in LDN and ODN groups. DUS showed initial turbulent flow in five of the LDN and four of the ODN group with an average RI of 0.59 and 0.66 in the ODN and LDN groups, respectively (NS). Three patients in the ODN group had an abnormal RI compared to none in the LDN group (p = 0.034). The creatinine values, creatinine clearances (at 24 h, one, four wk and last follow-up) and AR episodes were similar in both groups. Pneumoperitoneum during LDN does not appear to have an adverse impact on early graft reperfusion. [source]

Kidney and Pancreas Transplantation in the United States, 1999,2008: The Changing Face of Living Donation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 4p2 2010
D. A. Axelrod
The waiting list for kidney transplantation continued to grow between 1999 and 2008, from 41 177 to 76 089 candidates. However, active candidates represented the minority of this increase (36 951,50 624, a 37% change), while inactive candidates increased over 500% (4226,25 465). There were 5966 living donor (LD) and 10 551 deceased donor (DD) kidney transplants performed in 2008. The total number of pancreas transplants peaked at 1484 in 2004 and has declined to 1273. Although the number of LD transplants increased by 26% from 1999 to 2008, the total number peaked in 2004 at 6647 before declining 10% by 2008. The rate of LD transplantation continues to vary significantly as a function of demographic and geographic factors, including waiting time for DD transplant. Posttransplant survival remains excellent, and there appears to be greater use of induction agents and reduced use of corticosteroids in LD recipients. Significant changes occurred in the pediatric population, with a dramatic reduction in the use of LD organs after passage of the Share 35 rule. Many strategies have been adopted to reverse the decline in LD transplant rates for all age groups, including expansion of kidney paired donation, adoption of laparoscopic donor nephrectomy and use of incompatible LD.

Chylous Ascites Requiring Surgical Intervention after Donor Nephrectomy: Case Series and Single Center Experience

Elective Surgical Patients as Living Organ Donors: A Clinical and Ethical Innovation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2009
G. Testa
We propose a new model for living organ donation that would invite elective laparoscopic cholecystectomy patients to become volunteer, unrelated living kidney donors. Such donors would be surgical patients first and living donors second, in contrast to the current system, which ,creates' a surgical patient by operating on a healthy individual. Elective surgery patients have accepted the risks of anesthesia and surgery for their own surgical needs but would face additional surgical risks when a donor nephrectomy is combined with their cholecystectomy procedure. Because these two procedures have never been performed together, the precise level of additional risk entailed in such a combined approach is unknown and will require further study. However, considering the large number of elective cholecystectomies performed each year in the United States, if as few as 5% of elective cholecystectomy patients agreed to also serve as living kidney donors, the number of living kidney donors would increase substantially. If this proposal is accepted by a minority of patients and surgeons, and proves safe and effective in a protocol study, it could be applied to other elective abdominal surgery procedures and used to obtain other abdominal donor organs (e.g. liver and intestinal segments) for transplantation.

Recipient Outcomes for Expanded Criteria Living Kidney Donors: The Disconnect Between Current Evidence and Practice

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 7 2009
Y. Iordanous
Older individuals or those with medical complexities are undergoing living donor nephrectomy more than ever before. Transplant outcomes for recipients of kidneys from these living expanded criteria donors are largely uncertain. We systematically reviewed studies from 1980 to June 2008 that described transplant outcomes for recipients of kidneys from expanded criteria living donors. Results were organized by the following criteria: older age, obesity, hypertension, reduced glomerular filtration rate (GFR), proteinuria and hematuria. Pairs of reviewers independently evaluated each citation and abstracted data on study and donor characteristics, recipient survival, graft survival, serum creatinine and GFR. Transplant outcomes for recipients of kidneys from older donors (,60 years) were described in 31 studies. Recipients of kidneys from older donors had poorer 5-year patient and graft survival than recipients of kidneys from younger donors [meta-analysis of 12 studies, 72% vs. 80%, unadjusted relative risk (RR) of survival 0.89, 95% confidence interval (CI) 0.83,0.95]. In meta-regression, this association diminished over time (1980s RR 0.79, 95% CI 0.65,0.96 vs. 1990s RR 0.91, 95% CI 0.85,0.99). Few transplant outcomes were described for other expanded criteria. This disconnect between donor selection and a lack of knowledge of recipient outcomes should give transplant decision-makers pause and sets an agenda for future research. [source]

Laparoscopic Procurement of Kidneys with Multiple Renal Arteries is Associated with Increased Ureteral Complications in the Recipient

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2005
Jonathan T. Carter
This study investigates the effect of renal artery multiplicity on donor and recipient outcomes after laparoscopic donor nephrectomy. Three-hundred and sixty-one sequential procedures were performed over a 4-year period. Forty-nine involved accessory renal arteries; of these, 36 required revascularization and 13 were small polar vessels and ligated. The 312 remaining kidneys with single arteries served as controls. Study variables included operative times, blood loss, hospital stay, graft function and donor and recipient complications. Kidneys with multiple revascularized arteries had a longer mean warm ischemia time (35.3 vs. 29.2 min, p = 0.0003), and more ureteral complications (6/36 vs. 10/312, p = 0.0013) than single-artery controls.
