Multivariate Analysis of Risk Factors for Long-Term Urethroplasty Outcome
The Journal of Urology, 2010
We studied the patient risk factors that promote urethroplasty failure. Materials and Methods: Records of patients who underwent urethroplasty at the University of California, San Francisco Medical Center between 1995 and 2004 were reviewed. Cox proportional hazards regression analysis was used to identify multivariate predictors of urethroplasty outcome. Results: Between 1995 and 2004, 443 patients of 495 who underwent urethroplasty had complete comorbidity data and were included in analysis. Median patient age was 41 years (range 18 to 90). Median followup was 5.8 years (range 1 month to 10 years). Stricture recurred in 93 patients (21%). Primary estimated stricture-free survival at 1, 3 and 5 years was 88%, 82% and 79%. After multivariate analysis smoking (HR 1.8, 95% CI 1.0 -3.1, p ϭ 0.05), prior direct vision internal urethrotomy (HR 1.7, 95% CI 1.0 -3.0, p ϭ 0.04) and prior urethroplasty (HR 1.8, 95% CI 1.1-3.1, p ϭ 0.03) were predictive of treatment failure. On multivariate analysis diabetes mellitus showed a trend toward prediction of urethroplasty failure (HR 2.0, 95% CI 0.8 -4.9, p ϭ 0.14). Conclusions: Length of urethral stricture (greater than 4 cm), prior urethroplasty and failed endoscopic therapy are predictive of failure after urethroplasty.
To assess the impact of prior urethral dilatation or DVIU on the outcome of anterior urethroplasty
International Journal of Endorsing Health Science Research
Background: Male urethral stricture has remained the major problem in urologic practice. Patients presenting with urethral stricture disease are commonly managed by dilatation, DVIU, and urethroplasty. Methodology: This is a descriptive study of male patients who underwent anterior urethroplasty at our setup from 5th August 2021 to 25th February 2022. We analyzed the age, duration, type, length, and location of the stricture and the surgical treatment outcome after urethroplasty. The post-operative catheter was removed after 3 weeks, and UFM is advised. Qmax (max flow rate) > 15 ml/sec was measured on UFM (uroflowmetry) on the 1st week, 6 weeks, and followed on 3 months. Final outcome in terms of success was assessed by uroflowmetry. A maximum urine flow greater than 15mL/s after 3 months’ treatment assessed by uroflowmetry was considered as success. Results: In our study, the blood loss in group A and group B patients, those patients who had DVIU or dilation in the past, had mor...

Objectives: To evaluate the success rate of redo anastomotic urethroplasty and to compare it with primary anastomotic urethroplasty.Methods: We compared 52 patients with post-traumatic posterior urethral strictures (group 1, mean age 24.6 years, range 10–62) who had undergone redo urethroplasty with 66 patients (group 2, mean age 22.6, range 6–71) who had undergone primary anastomotic urethroplasty. Mean stricture length was 2.0 cm (1–4.5) and 2.5 cm (1.5–6), respectively. All of the patients in group 1 had a stricture located at the bulboprostatic anastomotic site. In group 2, 43 (65.2%) had a bulbomembranous stricture and 23 (34.8%) had a prostatomembranous stricture.Results: Mean operative time was 140 (100–240) and 90 min (75–200) in group 1 and 2, respectively. Mean blood loss was 180 (80–900) and 125 mL (50–700), respectively. Mean hospital stay was comparable (6.6 days vs 5.5 days) between the two groups. Mean follow up was 54 months (10–144) for group 1 and 62 months (12–122) for group 2. Corporal separation, inferior pubectomy, a transpubic approach and urethral rerouting were required in 22 (42.3%) and 12 (18.2%), 7 (13.5%) and 3 (4.5%), 12 (23%) and 5 (7.6%), 2 (3.8%) and nil patients in group 1 and 2, respectively. An excellent or acceptable outcome was achieved in 42 (80.8%) and 57 (86.4%), 8 (15.4%) and 7 (10.6%) patients, respectively. Two patients in each group failed.Conclusions: Previously failed end-to-end urethroplasty does not alter the success rate of redo end-to-end urethroplasty.

We retrospectively collected the data of 448 consecutive patients affected by urethral stricture who received surgery at University of Southern California of Los Angeles (USC) and University of Rome (UCBM) from 1998 to 2014. Patients were categorized based on the length of stricture in three different groups: group A 1-1.9 cm; group B 2-3cm and group C >3.1 cm. Urethral stricture etitologies and features (site and length) are showed in Table 1. Patients underwent urethroplasty according to the same technique. We performed end-to-end anastomosis for stricture <2cm (group A) and ventral buccal mucosa graft urethroplasty for patients with stricture >2cm (groups B and C). Comparative outcomes between the groups (by lenght) were assessed using analysis of a chisquare test. A logistic regression was used to calculate the odd ratio of success compared to the length. Statistical analysis was performed using STATA version 14.0 with 0.05 set as the level of significance. Database was analyzed to understand the impact of different urethral stricture lengths and etiologies on success rates. We collected data about one-year follow-up. All patients underwent urethral-cystoscopy and flowmetry at 1-6-12 month. Success was set as absence of urinary flow obstruction (no sign of endoscopic stricture and Q max > 10 ml/sec).

Introduction: incidence of urethral stricture recurrence ranges between 2% to 36.4% with 75% occurring within the first 6 months of surgery. Hence, they need to identify the predictors of recurrence following urethroplasty. Methods: this is a retrospective study involving patients that had urethroplasty from January 2008 to December 2017. Patients' records were reviewed. Analyzed data were for patients with a minimum follow up of one year from the time of urethroplasty and included aetiology of urethral stricture, presence of suprapubic cystostomy, prior urethral dilatation, urine M/C/S, site of urethral stricture, length of urethral stricture, type of urethroplasty, level of training of the surgeon, type of urethral stent used and duration of stenting. Analysis was done using SPSS version 23. P-value of < 0.05 was considered significant. Results: eighty seven urethroplasties were done, from January 2008 to December 2017. However, only records of 44 patients were accessible. Twenty patients completed duration of follow up ≥ one year. Urethral stricture recurrence was defined as resurgence of Lower Urinary Tract Symptoms (LUTS) within one year. Median age of the patients was 39.5 (± 19) years. Urethral stricture recurrence rate was 25% with mean time to recurrence from urethroplasty of 5.3 (±3) months. The use of preoperative suprapubic catheter (SPC) for urinary diversion as well as urethroplasties performed by the consultants had a lower incidence of recurrence. Conclusion: this study found urethral stricture recurrence of 25%. The level of training of surgeon vis-à-vis the expertise and experience seems to be an important factor, though not statistically significant in determining the outcome of urethroplasty.
Assessment of the short-term functional outcome after urethroplasty: a prospective analysis
International Braz J Urol, 2011
Objectives: To assess the short-term functional outcomes on urinary symptoms, erectile function, urinary continence and patient's satisfaction after urethroplasty. Materials and Methods: A prospective analysis was done in 21 patients who underwent urethroplasty. An assessment of the urinary flow, urinary symptoms (International Prostate Symptome Score ), erectile function (International Index of Erectile Function-5 ) and urinary continence (International Consultation Committee on Incontinence Questionaire male Short Form ) was done before urethroplasty and 6 weeks and 6 months after urethroplasty. Patients were also asked to score their satisfaction with the urethroplasty after 6 weeks and 6 months. Results: Mean patient's age was 48 years (range: 26-80 years). Mean stricture length was 4.2 cm (range: 1-12 cm). Three patients suffered a stricture recurrence. Mean maximum urinary flow increased from 5.83 mL/s to 24.92 mL/s (p < 0.001). Mean IPSS preoperative, 6 weeks and 6 months postoperative was respectively 15.86, 4.60 and 6.41(p < 0.001). The mean IIEF-5 score preoperative, 6 weeks and 6 months postoperative was respectively 15, 12.13 and 11.62 (not significant). The mean ICI-Q-SF score preoperative, 6 weeks and 6 months postoperative was respectively 10.47, 8.33 (p = 0.04) and 9.47 (p = 0.31). Patient's satisfaction 6 weeks and 6 months postoperative was respectively 17.14/20 and 17.12/20. Conclusions: Urethroplasty leads to a significant improvement in urinary flow and IPSS and urinary continence is tending to improve. Although not significant, erectile function was slightly diminished after urethroplasty. Functional outcome should be assessed when urethroplasty is performed.
Trends in urethral stricture management over two decades

To identify trends in the management of urethral stricture disease in Australia, assess changes in the standard of care, and examine the availability of genitourinary reconstructive surgery. Methods Data on eight stricture management procedures were collected online via Medicare Item Reports from the Australian Government Department of Human Services, and then matched to population data from the Australian Bureau of Statistics. A survey was disseminated via the Urological Society of Australia and New Zealand (USANZ) asking whether active members performed urethroplasty and whether this was done in a rural, regional or metropolitan setting. Results Over a 22-year period, there were 140 540 endoscopic procedures and 5136 urethroplasties, with 27.4 endoscopic procedures per urethroplasty. From 1994 to 2016, the per capita number of passage of sounds and dilatation procedures decreased by 74% and 75%, respectively, with increases in use of optical urethrotomy of 70% and in single-stage urethroplasty of 144%. Overall, the ratio of all endoscopic procedures vs urethroplasty decreased from 58.9 to 16.8. There were as few as 16 surgeons in the USANZ performing urethroplasty, with seven providing this service in regional areas. Seven had formal fellowship training. Conclusion There has been a clear shift from repetitive endoscopic procedures towards urethroplasty, but the former still make up the majority of interventions. This may be explained by patients not being referred for urethroplasty earlier in the course of disease and there appears to be a gap in genitourinary reconstructive expertise in regional and rural areas.
Redo-urethroplasty for the management of recurrent urethral strictures in males: a systematic review
World Journal of Urology
Purpose Redo-urethroplasty is a challenge for any genitourethral surgeon, with a number of techniques previously described. This systematic review aims to identify the surgical techniques described in the literature and evaluate the evidence for their effectiveness in managing recurrent urethral strictures. Materials and methods A systematic review of the MEDLINE and EMBASE databases from 1945 to July 2018 was performed and the urethroplasty procedures were classified according to the site and surgical technique. Primary outcomes included success rates measured via re-stricture rates and the post-op maximum urinary flow rate. Secondary outcomes included complication rates and patient-reported quality of life. Results A total of 39 identified studies met the inclusion criteria. Twenty-two studies described the use of excision and primary anastomotic urethroplasty with success rates showing wide variability (58-100%). Success rates reported according to the site of the stricture also varied: bulbar (58-100%) and posterior (69-100%) recurrent strictures. One-stage substitution urethroplasty was described in 25 studies with success rates of 18-100%, with the best outcomes reported for bulbar (58-100%) and hypospadias-related (78.6-82%) strictures. Two-stage substitution urethroplasty was described in 12 studies with the success rates of 20-100%, with the best evidence related to hypospadias-related and posterior urethral strictures. The buccal mucosa graft was the graft source with the best evidence for substitution urethroplasty (18-100%). Conclusions Trends of effectiveness were identified for redo-urethroplasty modalities in different locations. However, the current levels of evidence are limited to small observational studies, highlighting the need for further larger prospective data to evaluate different techniques used for recurrent urethral strictures.
Urethral Stricture Score is Associated with Anterior Urethroplasty Complexity and Outcome
Journal of Urology, 2016
Purpose: Several surgical techniques are available to treat anterior urethral stricture. The choice of surgical technique largely depends on the severity of stricture disease. The U-score (urethral stricture score) is based on urethral stricture characteristics, namely length (1 to 3 points), number (1 or 2 points), location (1 or 2 points) and etiology (1 or 2 points), which are tallied to provide a total score of 4 to 9 points. Our aim was to identify whether the U-score system is predictive of the surgical complexity and outcome of anterior urethroplasty. Materials and Methods: We retrospectively reviewed the records of all patients who underwent anterior urethroplasty from 2002 to 2012 by examining our prospectively collected urethroplasty database. We calculated the U-score and looked for an association with surgical complexity, recurrent stricture and time to recurrence. We defined recurrent stricture as the need for a secondary procedure. Results: There were 341 patients who underwent low complexity urethroplasty (anastomotic, buccal mucosal graft and augmented anterior urethroplasty) with a mean U-score of 4.7 while 48 underwent high complexity urethroplasty (double buccal mucosal graft, flap and graft/flap combination) with a mean score of 6.9. Higher U-score was predictive of higher surgical complexity (p <0.001). U-score was also significantly associated with recurrence. There was a consistent increase in the risk of recurrence with each additional U-score point. However, there was no association of U-score with time to recurrence. Conclusions: We confirmed the validity of U-score to predict the complexity of surgery for anterior urethral strictures. For the first time to our knowledge we report an association between higher U-score and anterior urethroplasty outcome. The U-score could be used to risk stratify patients and help with perioperative counseling.
