DALLAS June 15, 2011 A pediatric urologist at UT Southwestern Medical Center who pioneered a surgical technique for repairing a common birth defect in boys reports the procedure is singularly effective in correcting the problem with few complications.
Hypospadias, the second most common birth defect in boys, causes the opening of the urethra to be misplaced on the penis. If not corrected properly, the malady can lead to urinary tract infections and difficulty with urination and normal sexual activity.
Dr. Warren Snodgrass, professor of urology and chief of pediatric urology at UT Southwestern and Children's Medical Center Dallas, examined data from an eight-year period to assess how successful the procedure is in correcting hypospadias.
The results, published online in the Journal of Pediatric Urology, demonstrated a postoperative success rate better than 95 percent. Dr. Nicol Bush, assistant professor of urology, assisted in the assessment.
"Our data and patient outcomes proved that this technique is universally applicable for distal hypospadias, regardless of anatomy, which varies from patient to patient," Dr. Snodgrass said.
Called tubularized incised plate (TIP) repair, the surgery can repair both distal and proximal hypospadias. Distal hypospadias means the opening to the urethra, or urethral meatus, is closer to the tip of the penis than proximal hypospadias, and is typically easier to repair.
In the early 1990s Dr. Snodgrass developed the TIP repair, which is now the most commonly used technique for distal hypospadias repair throughout the world. The procedure uses tissues that normally create the urinary channel, without the need for skin flaps, which had been commonly used for more than a century.
The newer technique is less complicated and leaves the penis with a more natural appearance.
The clinical investigation looked at data obtained between 2000 and 2008 on more t
