[Transurethral balloon dilatation of the prostate: initial results, indication and complication].

Transurethral balloon dilatation therapy was performed on 40 patients with benign prostatic hypertrophy (BPH) under local anesthesia. During the procedure, urinary urgency occurred in 80% of the patients. After prostatic dilatation, macrohematuria was observed in almost all patients. The longest follow-up period after dilatation was now 22 months, and the average was 9.5 months. After treatment, residual urine volume decreased, and average flow rate and maximal flow rate improved from 5.7 and 10.4 ml/sec to 8.2 and 15.6 ml/sec, respectively. Overall clinical efficacy was 67.5%. Urethral dilatation therapy was thought to be an effective and non-invasive therapy for BPH.
