Postvoid Residual (postvoid + residual)
Terms modified by Postvoid Residual Selected AbstractsResidual Urine as a Risk Factor for Lower Urinary Tract Infection: A 1-Year Follow-Up Study in Nursing HomesJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2008Ragnhild Omli RN OBJECTIVES: To determine whether postvoid urine is a risk factor for the development of lower urinary tract infections (UTIs) in nursing home residents. DESIGN: Prospective surveillance with a follow-up period of 1 year. SETTING: Six Norwegian nursing homes. PARTICIPANTS: One hundred fifty nursing home residents. METHODS: Postvoid residual (PVR) urine volumes were measured using a portable ultrasound. UTIs were registered prospectively for 1 year. RESULTS: Ninety-eight residents (65.3%) had a PVR less than 100 mL, and 52 (34.7%) had a PVR of 100 mL or greater. During the follow-up period, 51 residents (34.0%) developed one or more UTIs. The prevalence of UTI in women was higher than in men (40.4% vs 19.6%; P=.02). There was no significant difference in mean PVR between residents who did and did not develop a UTI (79 vs 97 mL, P=.26). PVR of 100 mL or greater was not associated with greater risk of developing a UTI (P=.59). CONCLUSION: High PVR is common in nursing home residents. No association between PVR and UTI was found. [source] Validation of the short forms of the incontinence impact questionnaire (IIQ-7) and the urogenital distress inventory (UDI-6) in a Turkish population,NEUROUROLOGY AND URODYNAMICS, Issue 1 2007Cetin Cam Abstract Aim To validate the Turkish versions of the IIQ-7 and UDI-6 for use in Turkish-speaking populations. Methods After establishing the test-retest reliability and internal consistency in a pilot study, 302 patients were enrolled in the study and general and subscale scores of the questionnaires were calculated. All participants underwent an urodynamic assessment. Results Both instruments showed a high internal consistency (Cronbach's alpha for the IIQ-7 and UDI-6 was 0.87 and 0.74, respectively) and test-retest reliability (Spearman's rho was 0.99 for both of the scales (P,<,0.001). 55.6% of the participants showed urodynamic abnormality and/or leakage. 39.7% had urodynamic stress incontinence (USI) and 15.9% had detrussor overactivity (DOA),±,USI. The mean scores of each IIQ-7 and UDI-6 were significantly higher in the USI, and DOA,±,USI groups compared with normal women. Women with DOA,±,USI scored highest in the IIQ-7 and UDI-6. The irritative subscale scores of the 1st and 2nd items of the UDI-6 were significantly higher in the DOA,±,USI group. The stress subscale scores of 3rd and 4th items of UDI-6 were significantly higher in the USI group. Women with postvoid residual (PVR) urine values greater than 50 ml had significantly higher obstructive subscale scores compared to the ones who had less residual volumes. Conclusions The Turkish translated versions of the IIQ-7 and UDI-6 are reliable, consistent and valid instruments for assessing symptom severity and the impact on QOL in Turkish speaking women with urinary incontinence.

Van Savage Abstract Aims To evaluate the acute and chronic urodynamic effects of electrically stimulated detrusor myoplasty in dogs. Methods Eight female mongrel dogs were studied acutely and six dogs chronically (0 to 12 weeks postoperatively). Bladders were wrapped with the rectus abdominis muscle, keeping an intact blood supply and at least two intercostal nerves of the flap preserved. Bladders were electrically stimulated with bipolar electrodes inserted into the muscle. Urodynamics and post void residual were measured post operatively in the acute studies and every 2 weeks for 3 months in chronic studies. Results Acutely, the increase in intravesical pressure was 45±7 cm H2O, which resulted in a postvoid residual of 26±3%. In the chronic study, increases of intravesical pressure sufficient to empty the bladder during myoplasty electrical stimulation were not sustained, although detrusor compliance and flap viability were preserved. Conclusions The electrically stimulated detrusor myoplasty worked well acutely to increase vesical pressure sufficient to empty the bladder, but the chronically stimulated myoplasty did not maintain efficient bladder emptying primarily due to electrode problems. Further studies with improved electrode material and placement are required before clinical application of the electrically stimulated detrusor myoplasty can be assessed. Neurourol.

[source] Improvements in overactive bladder syndrome after polypropylene mesh surgery for cystoceleAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 2 2009Nobuo OKUI Background: The International Continence Society has defined overactive bladder syndrome (OABS) by the following set of symptoms: ,urgency, with or without urge incontinence, usually with urinary frequency and nocturia'. OABS and cystocele often coexist. Aim: This study aimed to analyse the changes in the overactive bladder symptom score (OABSS) of women followed up for one year after anterior repair surgery performed using a polypropylene mesh. In this surgery, a tape with four straps designed for optimum tissue holding capacity was fixed to the obturator foramen. Material and methods: Thirty-four women were operated using the abovementioned mesh. The OABSS, maximal urinary flow rate (Qmax) and postvoid residual (PVR) volume were evaluated pre- and post-surgery. Results: We observed significant improvements in the OABSS and quality of life scores before and after one year of surgery. The surgery was significantly effective in improving urgency, daytime frequency, incontinence, the Qmax and the PVR volume. No significant change in nocturia was observed post-surgery. Conclusions: Our study confirmed the efficacy of the propylene mesh introduction surgery for cystocele for the improvement of OABS symptoms. [source] Long-term results of orthotopic neobladder reconstruction after radical cystectomyBJU INTERNATIONAL, Issue 6 2003J.N. Kulkarni Objective To assess, in a retrospective study, the long-term results of neobladder reconstruction after radical cystectomy, as this is the standard of care for muscle-invasive bladder cancer. Patients and methods Data were retrieved for all patients with muscle-invasive transitional cell carcinoma of the bladder treated by radical cystectomy and orthotopic neobladder substitution between 1988 and 1998. All perioperative and long-term complications were recorded. The voiding pattern, frequency of micturition and continence were assessed, and a complete urodynamic profile recorded. Results In all, 102 patients underwent radical cystectomy with orthotopic neobladder reconstruction in the study period; their mean (range) follow-up was 73 (36,144) months. Neobladder substitution was with an ileocaecal segment in 35 patients, sigmoid colon in 34 and ileum in 33. Early complications occurred in 32 patients (31%) although open surgical intervention was required in only nine (9%). The death rate after surgery was 3.9%. Late complications occurred in 31 patients (30%) and were primarily caused by uretero-enteric and vesico-urethral strictures (9% each). Most patients had daytime (89%) and night-time (78%) continence. The mean maximum pouch capacity (mL) and pouch pressure at capacity (cmH2O) were 562.5 and 23 (ileocaecal), 542 and 17.8 (sigmoid) and 504 and 19.1 (ileal), respectively; the mean postvoid residual was 29, 44 and 23 mL, respectively. Nine patients with ileocaecal neobladders, and 20 and seven with sigmoid and ileal neobladders, required clean intermittent catheterization. Twenty-four patients had recurrence of disease, of whom 20 died. Conclusions Orthotopic neobladder reconstruction requires complex surgery but has an acceptable early and late complication rate in properly selected patients. It provides satisfactory continence without compromising cure rates. [source] A prospective study of conservatively managed acute urinary retention: prostate size mattersBJU INTERNATIONAL, Issue 7 2000V. Kumar Objective To evaluate in a prospective study the medium- to long-term outcome of a policy of conservatively managing acute urinary retention (AUR), arising solely by bladder outlet obstruction caused by benign prostatic enlargement (BPE), and to identify the factors favouring a positive outcome of a trial without catheter (TWOC). Patients and methods All men admitted as an emergency with primary AUR caused by BPE (from August 1997 to March 2000) underwent a TWOC. The following variables were recorded; the nature and duration of any preceding lower urinary tract symptoms, previous episodes of retention, concomitant anticholinergic medication, coexisting constipation, alcohol as a precipitating cause of AUR, previous prostatectomy, confirmed urinary tract infection, residual urine drained on catheterization and prostate size, as determined by a digital rectal examination (DRE) carried out by one consultant urologist in all patients. Those voiding successfully were followed up prospectively using the International Prostate Symptom Score (IPSS), quality-of-life score, urinary flow rate measurement and ultrasonographic measurement of the postvoid residual (PVR). Results Of the 40 men with AUR, 22 (55%) voided spontaneously after removing the catheter and continued to do so with mean peak flow rates of 12.2 mL/s and mean PVRs of 69.6 mL over a follow-up of 8,24 months. These patients remained asymptomatic, with a mean IPSS of 5.2 and quality-of-life score of 0.9. These men had a mean prostatic size of 15.9 g and a mean catheterized residual volume of 814 mL, while in those who had an unsuccessful TWOC the mean prostate size was 27.5 g (P = 0.006) and a mean catheterized residual volume of 1062 mL (P = 0.09). Prostate size as assessed by the DRE was the most significant factor in predicting the outcome of a TWOC. Conclusion A TWOC is justified in the long-term for men presenting with AUR caused by BPE. Prostate size is the most important factor for predicting the outcome of such a trial. [source] Incomplete emptying and urinary retention in multiple-system atrophy: When does it occur and how do we manage it?MOVEMENT DISORDERS, Issue 6 2006Takashi Ito MD Abstract Neurogenic urinary retention can be a major cause of morbidity in multiple-system atrophy (MSA). However, the timing of its appearance has not been entirely clear, and neither have the medical and surgical modalities for managing patients. We present the data obtained from our uroneurological assessment and therapeutic interventions at various stages of MSA. We recruited 245 patients with probable MSA. We measured postvoid residuals (PVR) and performed EMG cystometry in all patients. The grand average volume of PVR was 140 mL (range, 0,760) in our patients. The average PVR volume was 71 mL in the first year, increasing to 129 mL in the second year and 170 mL by the fifth year. The percentages of patients with complete urinary retention, acontractile detrusor, and detrusor,sphincter dyssynergia (DSD) also increased. The increase in PVR resulted in a decrease in functional bladder capacity, together with an increase in detrusor overactivity and neurogenic sphincter EMG. Clean intermittent self-catheterization (CISC) was introduced in most patients. Bladder-oriented therapy (cholinergic agents) had a limited value, whereas urethra-oriented therapy benefited patients with DSD (surgery) for up to 2 years, but syncope occurred in a subset of patients (,-blockers). MSA patients present with large PVR by the second year of illness, and that large PVR secondarily causes urinary frequency. CISC is the recommended treatment for most patients. Urethra-oriented medication and surgery benefit patients who would have difficulty performing CISC, although careful consideration of the short-term efficacy and potential adverse effects of these alternatives is mandatory. © 2006 Movement Disorder Society [source] | ||||||||||
