Hypospadias repair at a tertiary care center: long-term followup is mandatory to determine the real complication rate.

ABSTRACT

PURPOSE: The field of reconstructive surgery for hypospadias is lacking standard techniques and followup. Most published series include complication rates after a short followup. We report and analyze the long-term outcome of primary hypospadias repair at a single tertiary care center. MATERIALS AND METHODS: We reviewed 1,061 operations performed at our institution between 1997 and 2010 and registered as hypospadias repair. The operations were performed in 543 patients born between June 1997 and June 2005. A retrospective database was created with information about hypospadias characteristics, surgery and followup. RESULTS: A total of 474 primary repairs were selected, excluding incomplete/incorrect files. Distal penile hypospadias was reported in 366 patients (77.2%), mid penile hypospadias in 54 (11.4%) and proximal hypospadias in 54 (11.4%). Initial repair technique was based on incised plate in 189 patients (39.9%), meatal advancement in 171 (36%), onlay flap in 82 (17.3%) and other or combined techniques in 25 (5.3%). Insufficient information was reported for 7 patients (1.5%). Mean age at first operation was 22.6 months (range 4 to 134) and mean followup after first operation was 34.0 months (0 to 145). Of the children 360 (75.9%) had a good long-term outcome and required only 1 procedure. Reoperation was needed in 114 patients (24.1%), of whom 54 (47.4%) underwent reoperation in the first year of followup. CONCLUSIONS: Overall a good long-term outcome without further complication was achieved in 75.9% of our cases. Of the 24.1% of patients who needed reoperation only 47.4% presented within the first year postoperatively, indicating the need for long-term followup when reporting outcomes of hypospadias repair.
