Abstract

PURPOSE: The outcome of a tubularized incised plate (TIP) urethroplasty for hypospadias was reviewed retrospectively, and compared with other procedures with respected to the success rate, complications and satisfaction.
MATERIALS AND METHODS
Between April, 1994 and July, 2001, 51 patients underwent a repair for hypospadias, by the same operator, using a transverse preputial island flap (TPIF; 7), an onlay island flap (OIF; 3), Mathieu (7) and tubularized incised plate (34) procedures. The operation time, period of catheterization, postoperative hospital days and complication rates for each procedure were also compared.
RESULTS
The mean operation time in the TIP group was 140 minutes, compared to 230 220 and 160 minutes in the TPIF, OIF and Mathieu groups, respectively. The mean admission periods in the TPIF, OIF, Mathieu and TIP group, were 14, 17, 11 and 10 days, respectively. The mean operation time and admission period was shorter in the TIP group than those of the other procedures. The incidence rate of an urethrocutaneous fistula was lower in the TIP group (23%: 8/34) than in the TPIF (43%: 3/7), OIF (66%: 2/3) and Mathieu groups (57%: 4/7). Postoperative satisfaction for the penis and meatus shapes was highest in the TIP group.
CONCLUSIONS
The TIP urethroplasty had better outcomes than the TPIF, OIF and Mathieu procedures with regard to the operation time, catheterization period, admission period and complication rates following the operations. TIP urethroplasty is thought to be the most economic method for the repair of hypospadias, and can be recommended as the first choice for its repair.
