Comparison of tubularized incised plate urethroplasty and onlay island flap urethroplasty techniques in the repair of primarily proximal hypospadias

PubMed ID: 28976350OBJECTIVES: To compare the success of the 'tubularized incised plate urethroplasty' (TIPU)' and 'Onlay island flap urethroplasty' (OIFU) techniques for the repair of primary proximal hypospadias. MATERIAL AND METHODS: A retrospective evaluation was made of the medical records of 68 patients with primary, non-complicated hypospadias, who were operated on in the Department of Urology, Ministry of Heal- th Ankara Education and Research Hospital, between January 1997 and December 2012. Patients who underwent hypospadias surgery with TIPU were labelled as Group 1 and the OIFU technique as Group 2. Patient age, native meatus localization, operation time, diversion type, surgical success and complication rates were all assessed. Surgical success was evaluated with direct vision of voiding and uroflowmetry at the time of catheter removal, then at 2 weeks, 6 weeks, 6 months and 1 year. RESULTS: Group 1 consisted of 43 patients and Group 2 of 25 patients. The mean age of patients was 6.4±3.1 years in Group 1 and 8.0±4.6 years in Group 2 (p=0.09). The mean operating time was significantly lower in Group 1. (Group 1- 104.8±16.8 min, Group 2-125.4±24.7min; p
