Abstract

Purpose

We report outcomes from tubularized incised plate repair of mid shaft and proximal hypospadias by a single surgeon.

Materials and Methods

Chart review of all patients undergoing mid shaft and proximal hypospadias was performed. Those with tubularized incised plate were divided into 2 groups for mid shaft and proximal repairs. Group 1 underwent single layer urethroplasty using chromic catgut suture, while group 2 underwent 2-layer polyglactin subepithelial closure. All patients had a dartos barrier flap, while spongioplasty was also done in group 2 when possible.

Results

A total of 30 patients underwent mid shaft repairs, while 35 had more proximal defects. Complication rates for mid shaft repairs did not differ between the 2 groups, and averaged 13%. However, complications in mid shaft vs proximal repairs (37%) were significantly different (p = 0.04). Overall complications (53% vs 25%) and incidence of fistulas (33% vs 10%) decreased in proximal repairs from group 1 to 2.

Conclusions

Tubularized incised plate repair was applicable for all mid shaft hypospadias cases and for those more proximal cases when ventral curvature could be straightened without plate transection and the incised plate was grossly supple. Outcomes were improved using 2-layer subepithelial tubularization of the neourethra. Results of mid shaft vs proximal hypospadias repairs are significantly different and should be reported separately.
