title: [Retrograde prostatic urethroplasty with balloon catheter].
abstract: Retrograde prostatic urethroplasty with balloon catheter was first described by Castaneda et al. in 1987. This procedure is performed using local anesthesia with modified angioplasty balloon catheter. We applied this technique in 5 cases, including benign prostatic hypertrophy in 4 and prostatic cancer with urethral stricture in 1. Improvement in clinical symptoms was seen in 4 patients. Uroflowmetry was performed in 3 patients and flow was improved. Urinary retention recurred a few days after the procedure in one other patient. This was though to be related to the predominant hypertrophy of the middle prostatic lobe. A strong urge to void is commonly present at the time of balloon dilatation. Transient hematuria is seen after the procedure. To prevent the risk of postprocedural incontinence, it is very important to avoid dilating the external sphincter. Further investigation is necessary for the evaluation of long-term results, but this procedure can be performed in poor risk patients since it is less invasive. Hence, retrograde prostatic urethroplasty with balloon catheter is thought to be useful treatment for urethral stricture in poor risk patients.
