Effect of Snodgrass and Duckett repair for children with middle and posterior hypospadias

Objective To study the effect of Snodgrass and Duckett repair for children with middle and posterior hypospadias. Methods One hundred and fifty-eight children with middle and posterior hypospadias (average age of 3.4 years old) were selected from March 2013 to May 2017 in Weifang People's Hospital, 85 cases were treated with Duckett repair and 73 cases with Snodgrass repair. The postoperative outcomes and postoperative complications of the two operative methods were retrospectively analyzed, and the satisfaction degree of the patients was followed up. Results For the children with middle urethral hypospadias, well-developed urethral plate, < 30 degree of curvature of the penis and preserving the ideal extension of urethral plate, the Snodgrass technique had obvious advantages. The mean operating time of Snodgrass was (110.68±23.16) min, which was obviously shorter than that of Duckett(151.05±20.16) min, and the difference was statistically significant (P< 0.05). And the incidence of postoperative complications of Sondgrass was also significantly less than that of Duckett (15.56% vs 28.89%, P< 0.05). For posterior hypospadias, Duckett was more advantageous than Snodgrass with higher cure rate (65.00% vs 32.14%, P< 0.05). Besides, Duckett had higher satisfaction rate than Snodgrass (P< 0.05). Conclusion For the children with middle urethral hypospadias, Snodgrass has obvious advantages for cases with well-developed urethra plate. For posterior hypospadias, Duckett is more advantageous than Snodgrass.
