Mp65-15 validity and Reliability of a Home-Based Guardian-Conducted Video Voiding Test for Voiding Evaluation After Hypospadias Surgery

Abstract

procedure was 39.8 months (range 10.8 -81.2) in the flap patients and 16.4 months (range 5.5 -44.5) in graft patients. The median time to presentation of a complication postoperatively was 3.9 months (range 0.43 e 36.5) in the flap group and 0.56 (range 0.49 e 8.2). In the flap group, 11 patients required another intervention, and of those, 6 required more than one operation. In the graft group, 1 patient required an additional procedure. Flap patients were more likely to be reoperated on (64.7% versus 6.3%, p<0.001). There was no significant difference in post-operative complications between cohorts (64.7% of the buttonhole patients experienced complications versus 31.3% in the free graft patients, p [0.055). There was no significant difference between cohorts in regards to patient age, preoperative testosterone administration, postoperative meatus location, and degree of chordee. None of the pre-operative factors were independently associated with the probability of developing complications using the logistic regression model. There was a significant difference in the proportion of tunneled flaps performed by two attending physicians (35.3%) and the proportion of free grafts performed by two attending physicians (75%), p[0.0221.CONCLUSIONS: Free graft reconstruction is significantly associated with lower re-operation rates compared to tunneled flap repair.
