Objectives: To report the 2-years follow-up of patients with bulbar urethral strictures treated with the new Allium TM Bulbar Urethral Stent (Allium BUS). Methods: The stent is a fully covered, selfexpendable, large caliber metal stent specially designed for the treatment of bulbar urethral strictures. The stent is comprised of a coiled super-elastic structure covered by a polymeric coating designed to prevent mucosal hyperplasia. The indwelling time is 12 months, after which the stent should have been removed. Sixty-four patients with recurrent bulbar stricture were treated with Allium BUS in 3 worldwide centers. Results: All stents were successfully inserted with no peri-operative complications. In a median follow-up of 25.5 months, the mean maximal flow rate following stent insertion was significantly higher compared to the pre-surgical flow rate (14 ml/sec vs 6.6 ml/sec, p < 0.0001). Longer indwelling time and shorter stricture length were significantly related to success rate. The main complications were stent migration, stent re-stenosis and urinary tract infections. Conclusions: The temporary placement of the Allium TM BUS showed encouraging results with long-term failure rate of only 25%.

The purpose of this study was to evaluate the long-term clinical efficacy of temporary placement of covered retrievable stents in the management of recurrent urethral strictures. MATERIALS AND METHODS. During the period December 1998-December 2005, 32 men and one adolescent boy (mean age, 48.6 years; range, 16-73 years) with recurrent urethral strictures underwent fluoroscopically guided insertion of a total of 68 stents. Patients without complications underwent elective stent removal 2 or 4 months after stent insertion. Rates of clinical success (long-term clinical and radiographic resolution of urethral strictures) were assessed. The Mann-Whitney U test was used to compare the duration of stent placement in patients with long-term clinical resolution with that in patients with stricture relapse. RESULTS. Clinical success was achieved in 18 (55%) of the 33 patients. The mean duration of stent placement in patients with clinical success was significantly different from that in patients who had recurrences (p < 0.0001). Stricture relapse did not occur in only four (20%) of 20 cases of stent placement for 2 months. All 14 stent placements lasting at least 4 months resulted in long-term resolution after a mean follow-up period of 3.6 years. The most common complications necessitating early stent removal were stent migration (33.8% of stents) and tissue hyperplasia (20.6% of stents). CONCLUSION. Placement of a covered retrievable stent for a minimum of 4 months is effective in inducing long-term resolution of refractory urethral strictures. Stent migration remains the largest obstacle in achieving adequate duration of stent placement.

Strictures near the external sphincter are a cause for concern. They can be managed by manipulation (e.g. urethral dilatation) or by anastomotic urethroplasty. strictures. This report presents the results of using a temporary metallic coil stent (UROCOIL-S) in 20 patients with recurrent bulbomembranous strictures. In 13 patients the stent was left in place for 10 months and was then removed by a simple manipulation. After a mean follow-up of 10 months (range 3-14), the stricture recurred in only 1 patient. approach and the results are encouraging.

Treatment of Bulbar Urethral Strictures. A Review, with Personal Critical Remarks
The Scientific World JOURNAL, 2003
This is a review article on treatment of bulbar urethral strictures with personal critical remarks on newer developments. As a treatment of first intention there exists 4 options : dilatation, urethrotomy, end to end anastomosis and free graft, open urethroplasty. Success rate of dilatation and visual urethrotomy after 4 years is only 20 en 40 % respectively. Laser urethrotomy could not fulfill expectations. End to end anastomosis obtains a very high success rate but is only applicable for short strictures. Free graft urethroplasty obtains success rates of ± 80 %. There is considerable debate on the best material for grafting. Buccal mucosa graft is the new wave, but this is not based on scientific data. Whether this graft should be used dorsally or ventrally is also a point of discussion. In view of the good results published with both techniques it is probably of no importance. Intraluminal stents are not indicated for complicated cases and give only good results in those cases wh...
Long-term results of a self-expanding wallstent in the treatment of urethral stricture
BJU International, 2004
To report the long-term outcome over 12 years of using the urethral Urolume wallstent (AMS, Minnetonka, MI, USA) for treating recurrent bulbar urethral stricture disease. The case-notes of 60 consecutive men with urethral Urolume wallstents placed for treating recurrent bulbar strictures were reviewed retrospectively. Information was collected on patient demographics, stricture aetiology, stent-related complications and the need for further surgery to treat stent- or stricture-related complications. The mean (range) age of the men was 58 (32-76) years. The most common cause of stricture was iatrogenic, arising after previous endoscopic surgery or after an indwelling catheter (45%). Thirty-five men had complications, with re-operation required in 27 (45%) of them. The most frequent nonsurgical complications were post-micturition dribble (32%) and recurrent urinary tract infections (27%). The most common surgical interventions required were transurethral resection of obstructing stent hyperplasia (32%), urethral dilatation or urethrotomy for stent obstruction or stricture (25%) and endoscopic litholapaxy for stent encrustation or stone (17%). The Urolume wallstent should only be used in patients who are unfit for or who refuse a bulbar urethroplasty.
A retrospective analysis of urethral strictures and their management at a tertiary care center

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.

Objectives. The high recurrence rate is still the major complication of endoscopic treatment of urethral stricture disease. To compare the outcome of patients who underwent direct vision internal urethrotomy (DVIU) and then followed a protocol that randomized them to either our urethral dilation protocol or consecutive DVIUs for the treatment of their urethral stricture. Methods. A total of 37 patients, who had undergone at least two DVIUs to treat their recurrent urethral strictures, were enrolled in this study. They were randomized into two groups. The etiology and location of the strictures were similar, and their length ranged from 0.5 to 2 cm in each group. In group 1 (n ϭ 18), the patients were observed by regular visits and uroflowmetry profiles after the initial DVIU and consecutive DVIUs were considered when the stricture recurred. In group 2 (n ϭ 19), patients received urethral dilations with Benique dilatators (maximal 21F) under intraurethral anesthesia, beginning 10 days after the initial internal urethrotomy, according to the following protocol: weekly for the first month, once after 3 and after 6 months, and then once each year. Results. After a median follow-up of 30 months, the urethral stricture recurred within 12 months in 55.6% (n ϭ 10) of group 1, and consecutive DVIUs were indicated. During the same follow-up period, recurrence was observed in 2 patients (10.5%), 9 months and 2 years after randomization, in group 2 (P Ͻ0.05). The mean maximal urinary flow rate in groups 1 and 2 at last follow-up was 7.8 Ϯ 3.7 and 21.0 Ϯ 8.7 mL/s, respectively (P Ͻ0.01). Conclusions. We suggest a regular, simple urethral dilation protocol for patients with recurrent bulbomembranous urethral stricture shorter than 2 cm, because this significantly allays the stricture recurrence rate, possibly eliminates the need for consecutive DVIU, and reduces morbidity.

The Management of Urethral Strictures and Stenoses at the John F. Kennedy Medical Center
International Journal of Clinical Urology, 2019
Abstract: Background: A urethral stricture is an abnormal narrowing of the urethra resulting from fibrosis in the surrounding corpus spongiosum. The prevalence is estimated to be 229–627 per 100,000 males and its effects on the quality of life of those with the disease are far-reaching. Documented male-to-female ratio in Port-Harcourt, Nigeria, showed a ratio of 31:1 indicating that urethral stricture is very rare in females. Objective: The objective of the study is to assess the approach and outcome of the management of urethral stricture and stenosis at the John F. Kennedy Medical Center. Material and Methods: This is a 7-month retrospective descriptive study assessing the management of 20 patients with urethral stricture at the John F. Kennedy Medical Center from January 2018 to August 2018. The patient’s medical records were retrieved form the record department and reviewed for age, etiology of urethral stricture, site of urethral stricture, procedure performed and postoperative complications. Result: A total of 20 male patients with urethral stricture or stenosis were included in the study. Study revealed that the predominant etiology of urethral stricture was post-traumatic accounting for 35% (7/20). Gonoccal urethritis caused urethral stricture in 30% (6/20) of patients while instrumentation was 20% (4/20). Most of the post-inflammatory stricture involved the bulbar urethra as well as the penile urethra. Urethral Dilatation 9/20 (45%) and resection plus end to end anastomotic urethroplasty 35% (7/20) were the procedures commonly used to manage urethral strictures mostly the bulbar and bulbo-penile parts of the urethra. Conclusion: Urethral stricture disease is a common cause of urological presentation to the urologist worldwide. Urethral dilatation is most commonly performed for urethral strictures due to its feasibility and much less technical challenge. The failure rate is nonetheless high therefore, urethroplasty remains the standard option if possible. Appropriate traffic regulations, judicious use of catheters and proper treatment of urethritis could reduce the incidence of urethral stricture disease.
