Abstract

Urodynamic studies were performed pre- and post-operatively in 21 cases of bladder outlet obstruction patients who were admitted to Seoul National University Hospital, during the period from March, 1982 to August, 1983. The following results were obtained. 1. Pre-operative maximum flow rates were below 15ml/sec in 20 cases and post-operative maximum flow rates were above 15ml/sec in 16 cases. 2. The pre-operative cystometric findings showed hyper-reflexia patterns in 7 cases(33%). Postoperatively hyper-reflexia patterns were disappeared in 4 cases of these cases. 3. The mean pre-operative prostatic urethral length was 5.9cm with prostatic plateau and the mean postoperative prostatic urethral length was 1.9cm without prostatic plateau. 4. In 3 cases of post-prostatectomy patients who had incontinence, urethral pressure profilometry and cystometry revealed normal maximum closing pressure and hyper-reflexia. 5. 8 patients with bladder neck contracture were treated by transurethral resection. Post-operative maximum flow rates were increased in all of these cases. In 5 cases, the maximum flow rates were above 15ml/sec.
