Under the direct endoscopic manipulation, 15 internal urethrotomies in 14 cases with urethral stricture were applied at our department from March to August, 1983.
Following results were obtained:
1. The cause of 14 cases hospitalized, were injury in 13 cases and tuberculosis in one. The sites of urethral stricture were anterior urethra in 8 cases and posterior urethra in 6. The managements before applying direct visual internal urethrotomy were dilatation in 1 case having tuberculous urethral stricture and initial cystostomy just after in 13 cases. In 3 cases of them, Otis internal urethrotomy and urethroplasty had performed in one previously.
2. The length of urethral stricture estimate on preoperative retrograde urethrogram was less than 0.5cm in 3 cases, 0.6 to 1.0 cm in 5, 1.1 to 2.0 cm in 2, and 2.1 to 3.0 cm in 4, all of them were less than 3.0 cm.
3. The periods of catheter indwelling postoperatively were less than 3 days in 6 cases, 4 to 7 days in 7 and more than 8 days in only one, predominantly less than 7 days in 13.
4. The maximum flow rates were excellent or improved postoperatively. Voiding cystourethrogram was more valuable than retrograde urethrogram in urethral stricture.
5. Epididymitis in 1 case and urethral bleeding in 2 as postoperative complications were present.
These results implied that the visual internal urethrotomy was a valuable method as the management before deciding to perform urethroplasty.
