outcome of tubularized incised plate (tip) urethroplasty: a single-center experience with 307 cases

introduction: in order to assess our skill in the tubularized incised plate (tip) urethroplasty technique in children with hypospadias. material andmethods: of 307 children (mean age 38 month) who received a tip urethroplasty, all had primary hypospadias. patients who were referred with complication were eliminated from our study. the hypospadias defects were subcoronal in 25 (8%), distal penile in 236 (76%), midpenile in 25 (8%), proximal in 14(4%) and unknown in 7(2%) cases. chordee was present in 53 (17.2%) patients. presence of complications requiring reoperation and overall general appearance was recorded. results: the mean follow-up was 36 (19-72) months. overall success rate was 70 % (215). re-operation was required in 92 patients (30%): for urethrocutaneous fistula in 79 (26%), complete disruption of the repair in 2(0.6%) cases and meatal stenosis requiring meatoplasty in 12 (3%). complete glans dehiscence occurred in 3 patients, which was repaired using the magpi technique. partial breakdown of the glans occurred in 10 cases which did not require further surgery. one case had a huge urethral diverticulum. conclusions: this technique is relatively common compared to other accessible operations, but attention to details is necessary in order to achieve good results. it appears that complications, such as fistulas and meatal stenosis are more common in this method than other techniques, which require more research in the future.
