Abstract:
Objective To compare two operative approaches for treatment of distal hypospadias. Methods One hundred and seven patients were recruited into the study. Group1(n=51) underwent OUPF and group2(n= 56) underwent TIPU repair. The results were analyzed with Chi-square and two Sided test. Results Operative times for OUPF and TIPU repair were (103±29) min and (92±21)min respectively (P>0.05). Fistula occurred rates were 7.8% (4/51)and 14.2% (8/56) (P>0.05). Satisfied rates for the appearance of the penis post-operation were 84.8% (39/46)and 87.8%(36/41) respectively (P>0.05). 87 patients were followed up. With mean follow-ups of 15 months (range 6 to 47) , the overall complication rates were 15.7% (8/51) and 32.1 % (18/56)(P<0. 05) for OUPF and TIPU repair. Only 4 of 51 patients (7.8%) undergoing OUPF underwent re-operations, compared to 15 of 56 patients (26.8%) undergoing TIPU repair (P<0.001). A plateau uroflow curve (vs normal bell curve)was observed in 33.3% (13/39)and 67.6(25/37) ,respectively(P<0. 001). The average flow rate was 9. 4 ml per second (range 3. 2 to 17. 1) in patients undergoing OUPF repair, compared to 6. 8 ml per second (3. 3 to 15, P<0. 05) for those undergoing TIPU repair. Mean peak flow rates were12.2 ml per second (range 3.9 to 22.9) and 8. 3 mi per second (range 3.7 to 18. 1, P<0.01) for OUPF and TIPU procedures. Conclusion OUPF is superior to TIPU in the surgical treatment of distal hypospadias.
