Surgical Management of Anatomic Bladder Outlet Obstruction in Males with Neurogenic Bladder Dysfunction: A Systematic Review.

CONTEXT: Surgical treatment of anatomic bladder outlet obstruction (BOO) may be indicated in males with neurogenic bladder dysfunction. A bothersome complication after surgery is urinary incontinence.

OBJECTIVE: To identify the optimal practice in the surgical treatment of anatomic BOO in males with neurogenic bladder dysfunction, due to multiple sclerosis, Parkinson disease, spinal cord injury (SCI), spina bifida, or cerebrovascular accident (CVA).

EVIDENCE ACQUISITION: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Medline, Embase, Cochrane controlled trial databases, Web of Science, and Google Scholar were searched for publications until January 2017.

EVIDENCE SYNTHESIS: A total of 930 abstracts were screened. Eight studies were included. The types of anatomic BOO discussed were benign prostate obstruction, urethral stricture, and bladder neck sclerosis. The identified surgical treatments were transurethral resection of the prostate (TURP) in patients with Parkinson, CVA or SCI, endoscopic treatment of urethral stricture by laser ablation or urethrotomy (mainly in SCI patients), and bladder neck resection (BNR) in SCI patients. The outcome of TURP may be highly variable, and includes persistent or de novo urinary incontinence, regained normal micturition control, and urinary continence. Good results were seen in BNR and endoscopic urethrotomy studies. Laser ablation and cold knife urethrotomy resulted in restarting intermittent catheterization or adequate voiding. Overall, a high risk of bias was found.

CONCLUSIONS: This systematic review provides an overview of the current literature on the outcome of several surgical approaches of different types of anatomic BOO in males with neurogenic bladder dysfunction. Identifying the optimal practice was impossible due to limited availability of high-quality studies.

PATIENT SUMMARY: The outcome of several surgical approaches in males with neurogenic bladder dysfunction with benign prostate obstruction, urethral stricture, or bladder neck sclerosis is overviewed. The optimal practice could not be identified.
