Abstract

A clinical evaluation was made with particular attention to the technique of surgical repair on 61 patients with hypospadias who had been admitted to the Department of Urology, Kyungpook National University Hospital during 10 years periods from January, 1976 to June, 1986. The results were as follows: 1. The patients were between 1 to 29 years. Only 15 patients (24.6 %) were found in the age group under 6 years and 10(16.3%) in the age group over 20. 2. The most common type of hypospadias was penoscrotal in 33 patients (54.l%) and associated anomalies were found in 16 (26%) in which the most common one was cryptochism in 9. 3. 61 patients underwent hypospadias repair in which one stage repairs were used 13 and two stage repairs on 48. In two stage repairs, chordectomies were performed on 35 patients and second stage urethroplasties on 35. 35 patients underwent chordectomy in which Byars technique were used on 32 and Nesbit technique on 3. In the 32 patients who underwent chordectomy using Byars technique, 29 (9l%) were successful, while 3 others had skin necrosis or incomplete chordee repair. 35 patients underwent second stage urethroplasty in which Byars technique were used on 30 and other techniques on 5. In the 30 patients who underwent second stage urethroplasty using Byars technique, 20 (67%) were successful, which 8 having fistulas and 2 urethral stricture. 13 patients underwent one stage repair in which Duckett techniques were used on 4, MAGPI techniques on 3 Devine-Horton techniques on 2 and other techniques on 4. In the 13 patients performed one stage repair, 9 were successful, while 4 had fistulas or skin necrosis. 4. Of 83 surgical procedures performed with chordectomy, second stage urethroplasty or one stage repair, complication was encountered in l7 (20.6%). Of which the most frequent one was fistula. Of the 10 observed fistulas, 5 responsed nicely to one additional repair, while 3 required more additional repair and 2 had been lost in follow-up.
