Abstract
Introduction: In 1994, Warren Snodgrass made a breakthrough by introducing the Tubularized incised-plate (TIP) urethroplasty. At first, the technique was used for the repair of distal hypospadias, but later, its use has been extended to proximal forms as well.
Objective: We aimed in this study to evaluate the outcome of the suturing technique (interrupted vs continuous) in TIP -urethroplasty for hypospadias repair.
Methods: This was a prospective randomized study, conducted on the visitors of the urology outpatient clinic of El-Sahel Teaching Hospital during the period from February 2018 to February 2020. This study included 128 patients who met the inclusion criteria, were randomly divided into two equal groups: group A included 64 patients underwent TIP technique using continuous sutures and group B included 64 patients underwent TIP technique using interrupted sutures.
Results: The mean of operative time in group A and B was 2.30 and 2.77 hours respectively with statistically significant difference between both groups (p value=0.003). As regard to postoperative complications, fistula formation in group B (14.1%) was greater than group A (12.5%), meatal stenosis in group A (6.3%) was greater than group B (4.7%) and glans dehiscence was reported in only one patient in group A (1.6%) and no patients in group B. Also, there was no statistically significant difference between both groups (table 4).
Conclusion: The type of suture technique had no significant effect on the occurrence of complications, cosmetic appearance, and urine stream after TIP repair. However, TIP repair using continuous sutures took shorter operative time than the same technique using interrupted sutures.
