Between 1977 and 1997, 29 patients with hypospadias were surgically treated by Hodgson type III urethroplasty at Tsukuba University Hospital. The duration of surgery ranged from 150 to 535 minutes with an average of 269.3 minutes and the urethral catheter was removed between 4 and 14 days (average 8.7 day) after surgery. The postoperative hospital stay ranged from 10 to 29 days with an average of 18.4 days. The overall success rate of initial surgery was observed in 18 of the 29 patients (62.1%). As early postoperative complications, urethral fistula and stricture were seen in 10 (34%) and 3 (10%) patients, respectively; of these four fistulas persisted. As late complications revealed by questionnaire, erectile disorder was observed in one case. To obtain a higher success rate on initial treatment, skillful surgical technique and selection of appropriate cases are required.
