    Abstract:
    BACKGROUND: Recent years have seen the development of a new generation of temporary urethral stents as an adjuvant option after direct vision internal urethrotomy (DVIU). Despite some early promising results, large series addressing their safety and outcomes are still lacking. OBJECTIVE: To report complications and outcomes from the largest series of patients receiving a temporary bulbar urethral stent to date. DESIGN, SETTING, AND PARTICIPANTS: We performed a retrospective analysis of bulbar urethral stenting procedures after DVIU in seven centers. Patients either refused urethroplasty or were not fit for surgery. The stents were removed after at least 6 mo in place unless complications requiring earlier removal occurred. SURGICAL PROCEDURE: DVIU with a cold knife or laser is performed, followed by stent placement. At the end of the treatment period, the stent is removed under cystoscopy with gripping forceps. MEASUREMENTS: All patients underwent postoperative follow-up (FU) for assessment of complications while the stent was in place. After removal, the FU schedule consisted of office evaluation at 6 mo and 12 mo, and then annually. Failure was defined as any treatment for urethral stricture after stent removal. RESULTS AND LIMITATIONS: A total of 49% of the patients experienced complications. The most frequent were discomfort (23.8%), stress incontinence (17.5%), and stent dislocation (9.8%). Some 85% of the adverse events observed were Clavien-Dindo grade <3. The overall success rate at median FU of 38.2 mo was 76.9%. The success rate was significantly lower if the stent was removed before 6 mo (53.3% vs 79.7%; p = 0.026). CONCLUSIONS: Temporary urethral stents may be a safe choice with satisfactory results in patients not undergoing urethroplasty. A stent indwelling time shorter than 6 mo provides worse outcomes that are comparable to those with DVIU alone. PATIENT SUMMARY: We assessed complications and outcomes after placement of a temporary narrow tube in the urethra after surgery to widen a narrowing of the urethra. The treatment is safe and easily reproducible with satisfactory results. Further studies are needed to confirm our findings.
