Purpose:
We determined outcomes of tubularized incised plate urethroplasty based on preoperative urethral plate configuration or width.
Materials And Methods:
Records of consecutive prepubertal boys undergoing tubularized incised plate distal hypospadias repair were reviewed. The urethral plate was characterized as flat, cleft or deep, and results in each group were noted. In addition, the width of the plate after separation from the glans wings before midline incision was measured in some patients, with outcomes determined according to those less than 8 mm versus 8 mm or greater.
Results:
Of 159 patients plate configuration was recorded in 143, widths in 48 and both in 46. Outcomes were determined at a mean of 8 months postoperatively. Overall, there were no cases of meatal stenosis and fistulas occurred in 3 patients (2%). No significant difference in results was predicted by plate configuration or width.
Conclusions:
Tubularized incised plate urethroplasty for distal hypospadias repair has a low complication rate regardless of urethral plate configuration or width. Therefore, this procedure is potentially applicable in all cases of primary distal hypospadias.
