Spray cryotherapy for the treatment of glottic and subglottic stenosis

THE LARYNGOSCOPE, Issue 3 2010
William S. Krimsky MD
Abstract Objectives/Hypothesis: Functional partial occlusion of the glottic and subglottic areas by stenosis and strictures is challenging to manage despite a variety of surgical and endoluminal approaches that are prone to complications and inconsistent outcomes. We report here the first three human cases of glottic and subglottic narrowing treated with spray cryotherapy alone or in combination with balloon dilation. Study Design: Institutional review board-approved clinical human trial. Methods: A 42-year-old female with idiopathic subglottic strictures, a 74-year-old female with glottic strictures and vocal cord stenosis following neck radiation, and a 33-year-old female with strictures from a previous tracheal stent were treated by four cycles of a 5-second cryotherapy spray alone or with balloon dilation. The effects of treatment were observed up to 6 months, 12 weeks, and 9 months, respectively. Results: In all cases, patency of the stenosed areas was achieved with minimal bleeding and at least some degree of normalization of the glottic and subglottic mucosa. Airway patency and laryngeal functions were restored without complications. Conclusions: The use of spray cryotherapy alone or in conjunction with balloon dilation is a promising and effective therapeutic approach to treating glottic and subglottic narrowing.

OBJECTIVE To report experience with holmium laser enucleation of the prostate (HoLEP) simultaneously with transurethral holmium laser cystolithotripsy (HLC) for managing bladder outlet obstruction (BOO) and associated vesical calculi; we also review previously reported cases of managing vesical calculi and associated BOO. PATIENTS AND METHODS The high-powered holmium laser is a very efficient multifunctional endourological instrument that effectively fragments calculi of all compositions and is capable of haemostatic cutting of tissue, resulting in minimal bleeding after prostatic resection. A prospective study was conducted from April 2003 that included 32 men who underwent simultaneous HoLEP with transurethral HLC at our institution. Demographic, laboratory, peri-operative and follow-up data were analysed. Complications during and after surgery were identified to assess the morbidity of procedure. RESULTS The mean (range) size of bladder calculi was 34.6 (12,70) mm and the preoperative weight of the prostate was 51.9 (11,172) g. Combined HoLEP with transurethral HLC was technically feasible in all patients, and all were stone-free after surgery. The mean operative duration was 97.7 (40,230) min, the weight of prostate tissue removed 34.6 (5,88) g, and the duration of catheterization and hospital stay 29.3 h and 34.8 h, respectively. Complications during and after surgery occurred in 12.5% and 15.6% of patients, respectively; all complication were minor and none caused any residual disability to the patient. No patient required a blood transfusion or developed clot retention. CONCLUSIONS Managing bladder stones and BOO with simultaneous transurethral HLC and HoLEP should be considered the treatment of choice for such cases. Stones of any size and composition, and prostates of practically any size can be treated endoscopically using the holmium laser, with acceptable morbidity once the technique is mastered. The review of previous reports suggested a need for a prospective study comparing endoscopic management of BOO and associated bladder stones, with medical management of BOO and extracorporeal shock wave lithotripsy/endoscopic lithotripsy for bladder stone.

Impact of prostate-specific antigen level and prostate volume as predictors of efficacy in photoselective vaporization prostatectomy: analysis and results of an ongoing prospective multicentre study at 3 years

BJU INTERNATIONAL, Issue 6 2006
ALEXIS E. TE
In a multicentre study from the USA, 3-year results of the high-power KTP laser prostatectomy are presented. The authors used preoperative PSA level as a marker of prostate volume and assessed its potential predictive value on the level of clinical efficacy for treating symptomatic BPH. They found that the overall results from the technique were positive and durable, and suggested that there was a significant difference in efficacy between patients presenting with a total PSA of <6 or >6 ng/mL. Many patients who have had a radical prostatectomy are followed for a prolonged period and several observations are presented from an Italian study of urinary incontinence. The authors present their detailed results, finding a considerable trend in incontinence and anastomotic stricture, which decreased over time. OBJECTIVE To report the 3-year results and analyse whether total prostate-specific antigen (tPSA) levels and prostate volume before treatment can predict the level of clinical efficacy of photoselective vaporization prostatectomy (PVP) for treating obstructive benign prostatic disease, as high-power potassium-titanyl-phosphate (KTP) laser prostatectomy was previously shown to be safe and to efficiently vaporize prostatic adenoma secondary to benign prostatic hyperplasia (BPH), with minimal bleeding and morbidity. PATIENTS AND METHODS From October 2001 to January 2003, 139 men (mean age 67.7 years, sd 8.7) diagnosed with obstructive lower urinary tract symptoms secondary to BPH, had PVP with an average 80 W of KTP laser energy, at six investigational centres. A subanalysis evaluating each patient for tPSA and prostate volume before PVP was conducted, with a long-term assessment of the primary efficacy outcomes at 3 years after PVP. Each patient was assigned to one of two subgroups according to the tPSA level (group 1, ,,6.0 ng/mL; group 2 ,,6.1 ng/mL) and evaluated separately. Each subgroup was assessed for changes from baseline in American Urological Symptom Index (AUA SI) score, quality of life (QoL) score, peak urinary flow rate (Qmax), prostate volume, and postvoid residual urine volume (PVR) at 1, 2 and 3 years after PVP. RESULTS All tPSA subgroups had a sustained improvement in all efficacy outcomes maintained through the 3 years. There was a statistically significant difference in the level of improvement between groups 1 and 2 (P < 0.05) in AUA SI and Qmax at 1, 2 and 3 years. The mean (sd) prostate volume for group 1 was 48.3 (16.7) mL (87 men), and was 83.1 (30.6) mL (52 men) in group 2. The mean percentage improvement in the AUA SI at 1, 2 and 3 years in group 1 and 2, respectively, was 86%, 92% and 85%, and 69%, 74% and 76%; the corresponding percentage improvement in Qmax was 194%, 185% and 179%, and 124%, 145% and 139%, respectively. Overall treatment efficacy in all patients evaluated showed a mean 83%, 79%, 71% and 165% improvement in AUA SI, QoL, PVR and Qmax, respectively. Adverse events were minimal and the re-treatment rate was 4.3%. CONCLUSIONS These results suggest that there is a significant difference in efficacy in patients with a tPSA of ,,6.0 ng/mL or ,,6.1 ng/mL before PVP. However, the overall results achieved with PVP were very positive and durable to 3 years, irrespective of tPSA level and prostate volume. [source]


Rotoresect for bloodless transurethral resection of the prostate: a 4-year follow-up

BJU INTERNATIONAL, Issue 1 2003

OBJECTIVE To report the results and long-term follow-up of transurethral resection of the prostate (TURP) with a new resection device, the Rotoresect (Karl Storz, Tuttlingen, Germany). PATIENTS AND METHODS Most endoscopic resection techniques for benign prostatic tissue aim for high ablation rates and minimal bleeding. Available resection electrodes are effective, but cause high blood loss (loop electrode), or less bleeding but poorer ablation rates (electrovaporization). To resolve these conflicts the Rotoresect was developed in 1995; it consists of a specially designed rotating resection electrode, driven by a micromotor, and a high-frequency current to enable simultaneous coagulation, vaporization and mechanical tissue removal during resection. To date, 84 patients with benign prostatic hyperplasia have had their prostate resected with this device (mean prostate size 46.0, sd 18.4 mL) and have been assessed for up to 4 years. RESULTS During resection there was very little bleeding, with no significant changes in haemoglobin or sodium levels. The mean (sd) duration of catheterization was 1.4 (1.1) days; the urinary peak flow rate was improved from 9.7 (3.2) to 24.2 (8.23) mL/s and the residual urine volume reduced from 187.3 (109.6) to 22.7 (19.5) mL. The International Prostate Symptom Score and quality-of-life index were both improved, from 24.0 (7.5) to 4.1 (2.7), and 4.2 (3.2) to 0.8 (0.9), respectively. Overall the results were stable during the 4 years of follow-up. CONCLUSION The Rotoresect combines the advantages of standard resection (high ablation rate) by actively rotating the resection electrode, and the haemostatic effect of electrovaporization (minimal blood loss) by simultaneous tissue coagulation and vaporization.
