Comparative study between continuous and interrupted suturing technique in Tubularized incised plate hypospadias repair

Abstract

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).
