Abstract:
PURPOSE: Transurethral resection of prostate(TURP) is the gold standard for the treatment of benign prostate hyperplasia(BPH) at the present. But many attempts have been made to develop minimally invasive method. We studied the efficacy of transurethral needle ablation(TUNA) of prostate for treatment of BPH. MATERIALS AND METHODS: We performed TUNA in 20 BPH patients including 13 patients with acute urinary retention. Preoperatively all patients were evaluated using urinary flow rates, International Prostate Symptom Score(1-PSS), Quality of life and cystoscopic examination. The urinary flow rates, 1-PSS and Quality of life were checked at 1, 3 and 6 months after TUNA in all patients. RESULTS: The average value of peak flow rate of the patients with urinary retention were 10ml/sec, 12ml/sec and 13ml/sec at 1, 3 and 6 months follow-up. The average value of Qmax of the patients without urinary retention were 9ml/sec preoperatively and increased to 13ml/sec, 13ml/sec and 14ml/sec at 1, 3 and 6 months postoperatively. 1-PSS of patients with urinary retention improved from average 26 at preoperation to 14, 13, 10 at 1, 3 and 6 months postoperatively. Quality of life of patients with urinary retention improved from average 5 at preoperation to 2, 2, 2 at 1, 3 and 6 months postoperatively. The average value of patients without urinary retention improved from average 26, 5 at preoperation to 14, 11, 11 and 2, 2, 2 at 1, 3 and 6 months follow-up. No patients complained of erectile dysfunction and retrograde ejaculation postoperatively. CONCLUSIONS: The result of our preliminary study suggest that TUNA can be considered to be a simple, safe and efficacious procedure for the treatment of BPH including urinary retention.
