Jeong, Sang Jai; Yoon, Jong Byung

Abstract

Fifteen patients with urethral stricture were treated with Otis urethrotome at our hospital during the period from November 1982 to August 1983. The results were as follows: 1. The age distribution ranges from 13 to 48years old, the mean of 15 cases was 34.7 years old, The causes of urethral stricture were traumatic in 13 cases and iatrogenic in 2. The sites of urethral stricture were anterior urethra in 8 cases and posterior in 7. The preliminary managements before internal urethrotomy were cystostomy in 11 cases, urethroplasty in 3 and internal urethrotomy with Maisonneuve urethrotome in 1. 2. The length of urethral stricture measured on preoperative retrograde urethrogram and < or =0.5 cm in 2 cases, 0.6-1.0 cm in 6, 1.1-2.0 cm in 3 and 2.1-3.0 cm. in 4, All of them revealed < or =3.0 cm. 3. The foley catheter was indwelled for the period from 2 to 6 weeks and mean duration of the indwelling catheter was 19.3 days; < or =3 weeks in 8 cases and >3 weeks in 7. 4. Satisfactory (> or =20 ml/sec) and improved maximum flow (15 to 19 ml/sec) were in 10 cases and unsatisfactory (< or =14 ml/sec) in 5, three of them followed visual internal urethrotomy and satisfactory results were obtained. The retrograde urethrograms were slightly improved postoperatively. 5. Postoperative complications noticed in 3 cases (20%); false way in 2 cases, urethral bleeding associated with fever in one. From above experience, we believe that internal urethrotomy is a valuable method for nearly all types of patent urethral stricture.
