To present the outcomes of using Amplatz renal dilators in the management of complex urethral strictures. From September 2011 to August 2015, 34 patients with complex urethral strictures were treated with Amplatz renal dilators assisted with internal urethrotomy. Evaluation included uroflowmetry, IPSS and post-void residual volume measurement. Under spinal anesthesia, sequential dilatations were performed with Amplatz renal dilators measuring from 8 Fr up to 24 Fr. Urethrotomy was sequentially performed. The mean stricture length was 2.6 (1.5-3.5) cm. Preoperative mean Qmax was 4.4( 3.2-9.6) ml/sec.

Aim: The study aimed to assess and compare urethral stricture (US) management outcomes, efficiency, and complications, treated by either Amplatz renal dilator or visual internal urethrotomy (VIU). Patients and methods: This prospective comparative study was carried out on 88 male patients with stricture urethra. All patients have performed a physical examination, ascending and micturition urethrography, urodynamic, and pelvic ultrasound. The patients were randomized divided into group 1 (Amplatz group) 44 patients treated with Amplatz dilator, and group 2 (VIU group) 44 patients treated with a cold knife. Patients were followed up at 15 days,3,6, and 12 months after the procedure. Result: The mean age was 41.2 (22-73) years. The mean stricture length in group 1 and group 2 was 1.01 ± 0.40 and 1.04 ± 0.30, respectively (p ¼ 0.421). The average IPSS score at baseline for group 1 and group 2 was 21.2 and 21.9 points, respectively. During the 12 months follow-up, IPSS improved, with average scores of 16.1 and 17.3 for group 1 and group 2, respectively (p > 0.05). The mean values of (Q max) between group 1 and group 2 at baseline, day 15, day 90 and 180 days showed no significant difference but at 12 months, (Q max) showed a higher significant difference in group 1 than group 2 (p ¼ 0.003). The post-void residual (PVR) displayed a significant decline in both groups from baseline. After 1 year, PVR showed that group 2 was a little higher than group 1 (no significance) compared to baseline The procedures were found effective without recurrence in all patients (both groups) during the 12 months (Q max > 15m/s). However, group 2 reported (11.4%) intra-operative bleeding, and (6.8%) extravasations. Conclusion: The guided urethral dilation and internal urethrotomy are safe, short time procedures, and offer satisfactory results with the advance to VIUD in Qmax at 12 months. No recurrence was documented in both groups after 12 months. VIU reported 18% intraoperative complication.

Introduction: Current methods for Urethral dilatation include filiforms and followers, metal sounds, balloon dilators, catheters of increasing size, introduction of a Council catheter over a guidewire, and coaxial dilators of increasing size. These methods however are effective but expensive and use of them is limited in many third world countries. In this retrospective study, we report the feasibility, complication and long-term follow-up of the newly Nelaton based urethral dilation method following by self calibration plan as a single referral center experience. Method: We reviewed the records of 333 men with urethral stricture longer than 1 cm over a 16-year period between March 2001 to December 2018. In this method the straight flexi-tip guide-wire is introduced through the urethra and advanced under cystoscopic vision. This wire then was used to guide the dilatation after withdrawal of the cystoscope. The tip of well-lubricated Nelaton urethral catheters incised and then advanced gently over the guide-wire serially from the smallest to the largest appropriate sizes. The patients were followed up regularly after the dilatation 1, 3, 6, 12 months and then annually postoperatively with taking history, PVR and uroflowmetry and all underwent retrograde urethrography at the 6 th and 12 th months of follow-up. Result: The mean age of patients was 39.19±16.9 years old (10 to 86 years). The mean period of the follow-up was 3.6±1.1 years (range, 3 to 4.3 years). Success rate after first attempted was 58.5% and after two attempted was 77.7% in two years follow up. After one year 51 (15.3%), two years 23 (6.9%) and after three years 11 (3.3%) cases required continued self dilatation once a month. Conclusion: Guide wire-assisted urethral dilatation is shown to be acceptable, cost-effective, simple, safe and feasible techniques for urethral dilation. Our technique may be the choice manner in selected patients with short memberanous urethral stricture, because of decrease the risk of incontinency.
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...
A retrospective analysis of urethral strictures and their management at a tertiary care center
ijnu.ir
Background: Surgical treatment of urethral strictures includes numerous options such as dilation, internal urethrotomy, stenting and reconstructive surgical techniques. Short uncomplicated strictures are generally amenable to complete excision with primary anastomosis. We performed a retrospective evaluation and analysis of outcome in patients who underwent any kind of treatment for urethral strictures. Objectives: To evaluate and analyze the outcome in patients who underwent treatment for urethral stricture disease over the last 15 years (May 1993 to June 2008), at a tertiary care centre, as well as to determine the treatment option to be utilized in different varieties of urethral strictures. Patients and Methods: We reviewed 524 patients who underwent treatment for urethral strictures between May 1993 and June 2008. Mean follow-up was 68 months. Preoperative evaluation included clinical history, physical examination, urine culture, residual urine estimation, uroflowmetry, and retrograde and voiding cystourethrography. Since 2000 urethral ultrasound was also performed in all patients. Clinical outcome was assessed by comparing pre and post operative investigation and patient satisfaction. Results: Stricture etiology was catheter induced (15.36%), blunt perineal trauma (59.2%), instrumentation (12%), spontaneous (3.52%) and infection (10%). Stricture length was 0 to1cm (in 9.92%) 1 to 2 cm (in 32%), 2 to 3 cm (17.28%), 3 to 4 cm (24%) or 4 to 5 cm (8.8%) more than 5cm (16%). The success rates in these procedures were 93.6% (TAU-Tunica albuginea urethroplasty), 94.4% (USPBA-U shaped Prostato-bulbar Anastomosis), 91.7% (BMSU-Buccal Mucosa urethroplasty), 90% (IOU-Internal optic urethrotomy), 90.35% (dilatation) and 81% (two staged urethroplasty). There were 129 patients (25.49%) who experienced ejaculatory dysfunction. Good and fair results were considered successful. Of 524 cases 480 (91.6%) were successful and 44 (8.4%) were treatment failures. Conclusions: We conclude that the treatment of urethral strictures should be individualized, taking into account the location, length and extent of spongiofibrosis.
Trends in urethral stricture management over two decades
BJU International
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.
Reconstruction of urethral strictures in patients with a long history of blind urethral dilatation
Urology journal, 2014
PURPOSE To compare urethral reconstructions in patients after several years with or without blind urethral dilatation. MATERIALS AND METHODS A retrospective study of 107 patients with urethral reconstructions was performed. Sixty patients with a long history of blind urethral dilatation (group 1) were compared with 47 patients without prior dilatations (group 2). RESULTS The type of surgery planned according to urethrography and endoscopy findings was appropriate in 37/60 (61.6%) patients in group 1 and in 39/47 (83%) patients in group 2(P < .03). Anastomotic repairs were more frequent among the patients in group 2 (P < .001).Eighty five out of 107 patients were available for the 24 months follow-up. The success rate was higher in group 2 (91.4%) than patients in group 1 (70%) (P < .04). The greatest improvement in symptoms and quality of life occurred three months after the surgery (P < .05).Postoperative infection was persistent in 20/107 (18.7%) patients. CONCLUSION U...
Urethroplasty in the management of urethral strictures: a literature review
International Journal Of Community Medicine And Public Health
Urethral stricture is defined as pathological urethral narrowing caused by corpus spongiosum fibrosis. The etiology of this condition is mostly idiopathic, which can also result from iatrogenic (like previous urethral surgeries, catheterization, or resection), inflammatory and traumatic causes. The evidence discussing the management of urethral strictures is scarce. The management starts with an appropriate evaluation of the condition through a comprehensive history taking (obstructive symptoms) and physical examination. Diagnostic investigations include cystoscopy (the most specific), urethrography, patient reported scales, like American urological association symptom index, uroflowmetry, and retrograde urethrography. Previous literature shows urethroplasty is cost effective, whether when it is used as the primary treatment or following a non-successful dilation and direct visualization internal urethrotomy. Moreover, open urethroplasty and endoscopic urethrotomy were comparable am...
Characteristics of the urethroplasty and our approach-Experience in patients with urethral stricture
Türk Üroloji Dergisi/Turkish Journal of Urology, 2018
Objective: Urethral stricture is a common pathology with different etiologic factors in different age groups and societies. In our research, patients who underwent urethroplasty because of urethral stricture were evaluated in terms of etiology, localization, surgical technique and demographic characteristics. Material and methods: One hundred and sixty-three patients with a mean age of 53.43±16.5 years, operated between January 2008 and May 2016 because of urethral stricture were retrospectively included in the study. Diagnosis of the urethral stricture was established based on the complaints of the patient, results of urinalysis, urine culture, uroflowmetry, retrograde urethrography and/or voiding urethrography, and urethroscopy in case of need. Postoperative success for the patients was determined based on urinary flow rate and maximum flow rate of over 15 mL/sec were evaluated as success. Results: Etiologic factors for urethral stricture included trauma in 40 (24.5%), urethral catheterization in 45 (27.6%), endoscopic procedure in 59 (36.2%), infection in 10 (6.2%), idiopathic etiologies in 9 (5.5%) out of 163 patients. Mean length of the stricture was 3.6±1.7 cm. While the indicated number of patients had buccal mucosa graft (n=73, 44.7%), penile skin flap (n=21, 12.8%), Heineke-Mikulicz repair (n=5, 3.0%), and end-to-end anastomosis (n=64, 39.1%). Mean follow-up period was 43.2±33.7 months. Buccal mucosa graft was applied as ventral (n=32, 43.8%), dorsal (n=22, 30.2%), and dorsolateral (n=14, 19.2%) onlay, and transventrally dorsal inlay (n=5, 6.8%) grafts. Average success rates were 83.5% (n=61/73) in buccal mucosa, 76.2% (n=16/21) in penile skin grafts; 85.9% (n=55/64) in end-to-end anastomosis and 80.0% (n=4/5) in Heineke-Mikulicz repair. Conclusion: Our assumption is that urethroplasty procedures have satisfactory long-term results, regardless of the location and size of the stenosis. According to our clinical experience, deciding on the most appropriate surgical technique by assessing each patient individually in experienced centers will increase success rates.
