Distal Penile and Mid-Shaft Hypospadias Repair:Tubularized lncized Plate (SNODGRASS) Urethroplasty Versus Tubularized Plate (THIERSCH-DUPLAY) Urethroplasty.

Abstract

Background:Hypospadias is one of the most common congenital anomalies of male extemal genitalia, in which the external urethral meatus exits ventrally any where from the glans to the perineum.There are many surgical modalities for reconstruction but with different rates of success. Aim:ls to compare between Tubularized Incised Plate urethroplasty (Snodgrass technique) and Tubularized Plate urethroplasty(Thiersch-Duplay technique) in reconstructing distal penile and mid-shaft hypospadias regarding success rates,types and incidence of complications and advantages of each technique. Patients and Methods:Patients were blindly assigned into two random groups-Group A (20 patients) were repaired by Snodgrass technique
and group B (20 patients) were repaired by Theirsh-Duplay technique.All patients were followed up for one year. Results: 40 patients with distal penile and mid-shaft hypospadias were studied. The majority were between 2-4 years of age.MeataI stenosis and urethrocutaneous fistulae were the most frequently encountered complications.  
Conclusions: Snodgrass technique is more superior than Thiersch-Duplay technique in terms of final aesthetic and functional results.
