Comparison of Tubulized Incised Plate and Other Procedures for Hypospadias / 대한비뇨기과학회지

ABSTRACT

PURPOSE: While numerous methods have been introduced to repair hypospadias, no single method is effective for repairing all hypospadias. We reviewed our experience of hypospadias repair to determine the best surgical method and the efficacy of the treatment modality. MATERIALS AND METHODS: We reviewed the hospital charts of 32 patients who had undergone hypospadias surgery from January 1993 to January 2002. Group 1 included patients who were operated on before 1998 and group 2 had those who had operations after 1998 with only the TIP(tubularized incised plate) method. The surgical procedures that were performed on the patients were onlay island flap(6), Mathieu(2), Hodgson's type III(2), Mustard(2), TIP(14), Transverse island flap(5), and Thiersch-Duplay(1). The mean operative time, mean hospital days, mean duration of catheter drainge, and complication rates of the two groups were compared. RESULTS: In group 2, operation time was reduced(142.9+/-69.4 versus 172.5+/-93.4 min)(p<0.05), but the two groups showed no significant differences in mean hospital days(11.9+/-2.8 days. versus 12.3+/-1.6 days) and mean duration of catheter drainge (9.8+/-24 versus 10.5+/-3.6 days). In group 1 and group 2, complication rates were 67% (12 of 18) and 14%(2 of 14), respectively(p<0.05). CONCLUSIONS: Our data show shorter operative time and lower complication rates using the TIP method for various types of hypospadias. Therefore, the TIP method seems to be a safe method of surgery for any type of hypospadias.
