Outcomes of Tubularized Incised Plate Urethroplastyin Proximal Hypospadias: A Single-Center Experience

Background: The aim of this study was to assess the outcomes of the tubularized incised plate (TIP) urethroplasty in the treatment of proximal hypospadias. Methods: A prospective study was conducted at Childrens Hospital 2 in Ho Chi Minh City from March 2012 through March 2015. Patients presented with proximal hypospadias were submitted for a TIP urethroplasty. Data were collected and analyzed in terms of patient characteristics, operative data, postoperative complications, and outcomes at least 6 months after the operation. Results: The 278 patients were enrolled in this study. Mean age of the patients was 3.6 2.8 years. Median follow-up time was 2.0 years [0.5 - 3.7 years]. The success rate of TIP urethroplasty was in 197/278 (70.9 %) patients. The 81/278 (29.1 %) patients reported with failure of TIP urethroplasty: urethral fistula in 57/278 (20.5 %) patients, partial urethral dehiscence in 18/278 (6.5 %) patients, and meatal stenosis in 6/278 (2.1 %) patients. Patients 3-year-old and length of neourethroplasty 3 cm were significantly associated with a risk of TIP technique failure with adjusted ORs: 1.9 [1.3 2.8], P=0.001 and 3.4 [1.7 6.8], P
