Comparative Study of Snodgrass and Mathieu's Procedure for Primary Hypospadias Repair.

Area of Science:

• Pediatric Urology
• Surgical Techniques
• Hypospadias Repair

Background:

• Hypospadias is a congenital condition requiring surgical correction.
• Single-stage repair techniques aim to optimize functional and cosmetic outcomes.
• Tubularized Incised Plate (TIP) and Mathieu's repair are common surgical options.

Purpose of the Study:

• To compare the efficacy and outcomes of TIP repair versus Mathieu's repair for distal penile hypospadias.
• To evaluate complication rates, operative time, and cosmetic results between the two surgical methods.

Main Methods:

• A comparative study involving 100 male patients with distal penile hypospadias.
• Patients underwent either TIP repair (52) or Mathieu's repair (48).
• Outcomes assessed included meatal position and shape, urinary stream, fistula, stricture, and operative time.

Main Results:

• TIP repair had a significantly shorter mean operative time (63.7 min) compared to Mathieu's repair (95.0 min).
• Complication rates: Urethrocutaneous fistula (5.76% TIP vs. 14.5% Mathieu), Meatal stenosis (5.33% TIP vs. 8.33% Mathieu), Wound infection (19.2% TIP vs. 8.3% Mathieu).
• TIP repair resulted in a more natural, slit-like, vertically oriented meatus in 92.3% of cases.

Conclusions:

• The Snodgrass (TIP) repair is a faster and more cosmetically superior technique for hypospadias compared to Mathieu's repair.
• TIP repair demonstrates favorable outcomes regarding meatal shape and potentially lower fistula rates.
• Further evaluation of wound infection rates between techniques is warranted.
