Abstract

The results with management of urethral stricture are disappointing, with a high rate of early and late recurrence. Recently, the success of internal urethrotomy has made us question the role of open urethroplasty in the management of urethral strictures. Thus a clinical evaluation was made on 26 pediatric patients with urethral stricture in the Department of Urology, National Medical Center, during the period from Sep. 1978 to Aug. 1992. The stricture was incomplete in 15 cases and complete in 11 cases. The length of stricture was less than l cm in 17 cases, 1 to 2 cm in 3 cases, more than 2cm in 3 cases and multiple stricture in 3 cases. The treatment modality of incomplete urethral stricture was internal urethrotomy in 12 cases and urethroplasty in 3 cases regardless of length. Incomplete urethral stricture, internal urethrotomy was carried out in 8 cases with less than 1 cm long stricture and urethroplasty in 3 cases regardless of length. But all complete urethral stricture was carried out urethroplasty initially. The overall out come in incomplete urethral stricture, average urine flow rate ranged from 8.5ml/sec to 11.4ml/sec and incomplete urethral stricture, average urine flow rate ranged from 7.0 ml/sec to 20 ml/sec. We think that visual urethrotomy is a valuable initial method, when stricture is incomplete and urethroplasty is a valuable initial method, when stricture is complete.
