외상성 완전요도협착 치료에 있어서 직시하 내요도절개술과 요도성형술의 비교

Abstract

Visual internal urethrotomy may be a reasonable initial procedure of complete and incomplete urethral stricture before planning more extensive urethroplasty. We reviewed our experience with 62 complete urethral strictures for 10 years. The outcomes of the treatment of 28 patients who were managed by visual internal urethrotomy were compared with those of 34 patients managed by urethroplasty. The overall successful results were 32.1% in visual internal urethrotomy and 85.3% in urethroplasty. When stricture length was less than l cm, success rate was 40 % in spite of several recurrences in visual internal urethrotomy, comparable to the success rate of 12.5% in case of stricture length more than 1 cm. We recommended that visual internal urethrotomy as an applicable initial method before urethroplasty, when stricture is less than 1 cm in cases of complete urethral stricture.
