Application of green light laser in complex posterior urethral stricture after surgical treatment of benign prostatic hyperplasia / 中华泌尿外科杂志

ABSTRACT

Objective To investigate the effect of green light laser in complex posterior urethral stricture after surgical treatment of benign prostatic hyperplasia (BPH).Methods Green light laser was applied in treating 20 cases of complex iatrogenic posterior urethral stricture.Of these cases,12 had false passages,5 had more than 2 strictures and 5 had concurrently urethratresia.The scar tissues were transure- thrally vaporized and resected.The in-dwelling urethral catheter time was 1-2 months after operation. Results All the patients were initially cured without serious complications.The mean operative time was 39 rain (range,30-65 min).During the follow-up of 2-10 months,1 case had mild incontinenceanother case (Q_(max)＜9ml/s 2 weeks after surgery) got satisfactory results(Q_(max)＞15ml/s)after the scheduled urethral dilatation.The other 18 cases were treated successfully and voided fluently with postoperative Q_(max)＞15ml/s in all.Conclusions It is suggested that transurethral green light laser procedure is not only safe and ef- fective,but also simple and minimally iuvasive for complex posterior urethral stricture following surgical treat- ment of BPH.
