A clinical observation on urethroplasty in 49 cases with urethral injury among 1150 patients which were admitted for urologic operation at department of urology, St. Mary`s Hospital, C.M.C. during the period from Jan. 1966 through Aug. 1971 were performed. Of 49 cases, 37 cases were urethral rupture and remainder, urethral stricture. The urethral rupture was repaired by suprapubic urethroplasty and urethral stricture, by perineal urethroplasty (end to end anastomosis). The results were summarized as follows: 1. The rate of GU injury accounted for 9. 14% to the total operated inpatient and the rate of urethral injury for 46.7% to the G-U injury during 5 years and 8 months 2. The incidence of the urethral injury was the highest in the age of 21 to 30, and majority of the urethral injury (67. 3%) was lied between the age of 21 and 50. 3. The most common cause of the urethral injury was car accident (57, 1%) and others, recorded in the order of straddle injury and kick and blow. 4. Among 37 cases of urethral rupture, pubic bone fracture was associated in 19cases (51. 4%). 5. Removal of urethral catheter after urethroplasty were 2 ~ 3 weeks in cases of urethral rupture and 1 ~ 2 weeks in the cases of urethral stricture. 6. 12 cases (100%) with urethral stricture were treated by perineal urethroplasty (end to end anastomosis).
