[Stricture of the vesicourethral anastomosis after radical prostatectomy].

BACKGROUND: The development of a stricture of the vesicourethral anastomosis is a serious complication after radical prostatectomy. Strictures occur in 5-8% of patients after radical prostatectomy. SYMPTOMS: Usually the clinical symptoms include an irritative and obstructive component similar to benign prostatic hyperplasia. In rare cases, patients suffer from partial or complete stress incontinence as a result of the anastomotic stricture. DIAGNOSTICS: The diagnostic workup is similar to the procedure for urethral strictures. In addition to uroflowmetry, a cystourethrogram (CUG) or, if necessary, a micturating cystourethrogram (MCU) can be performed. A urethrocystoscopy can be performed to ensure the diagnosis. THERAPY: In most cases, endoscopic procedures were performed for treatment. Beside a transurethral dilation of the stricture or the Sachse urethrotomy, the most common procedure is transurethral resection to treat the stricture. However, all procedures are associated with a high recurrence rate. In recurrent strictures, open surgical procedures, usually a perineal reanastomosis, should performed early.
CONCLUSION: Endourological procedures like transurethral resection are a good treatment option, but due to the high recurrence rates, open surgical procedures should be discussed and if necessary should be performed early.
