RESUMO
Objective To introduce an optimal incision technique in the endourethral surgery for urethratresia. Methods Sixteen patients suffering from urethratresia were managed by endourethral surgery,2 of them treated with rotator incision and the other 14 with rotator incision plus transurethral scar electrosectomy.The efficacy of the treatment was evaluated by Qmax. Results Successful incisions were achieved in all patients,the duration of procedure being from 18 to 33 min,with a mean of 25 min.Two patients with rotator incision had dysuria (Qmax 9 and 7 ml/s) after the surgery and accepted transurethral resection of scar again.The other 14 patients with rotator incision plus transurethral scar electrosectomy had good voiding.Qmax was more than 16 ml/s in all patients after operation. Conclusions Rotator incision is a safe,simple,efficacious incision technique in the endourethral surgery for urethratresia,and scar electrosectomy is essential for successsful outcome.
