UT Southwestern surgeons examine hypospadias repair efficacy for patients with differing anatomies
Date:6/14/2011

han 550 patients ages 3 months and older who had TIP repair. Surgeons obtained follow-up on 77 percent of the cases. No anatomical contraindications to doing the TIP repair were reported and the complication rate was around 4 percent.

"Urinary flow appeared normal in our patient group, and we found that all forms of distal hypospadias can be corrected with good results," Dr. Snodgrass said. "The data is very encouraging and we hope it will decrease confusion about the circumstances in which the TIP procedure is applicable."

The results have encouraged the use of TIP for the more challenging proximal hypospadias repair, which accounts for about 10 percent of cases. In a previous study published in the Journal of Pediatric Urology, Drs. Snodgrass and Bush described technical improvements that have reduced complications from 53 percent to 13 percent; using skin flap techniques, the expected complication rate remains more than 30 percent.

They also published outcomes in the Journal of Urology that provide an algorithm for reoperations in patients with complications from initial surgery, again without need for skin flaps.

Taken together, these studies cover the spectrum of hypospadias repair using innovative operative techniques that are a radical departure from earlier surgical practice.
