Abstract Background About one in 200 to one in 300 male births has hypospadias. The prevalence of this congenital anomaly varies worldwide. The meatus is located distally in approximately 70% of cases. Several surgical techniques were described for distal hypospadias repair; despite this, there is no ideal approach. This study compares urethral advancement &glanuloplasty, and TIP techniques in terms of feasibility, duration of operation, and complications. Patients and. Methods This prospective randomized comparative study was conducted at Al-Azhar University Hospitals from April 2022 to October 2022. Fifty-seven cases with different types of hypospadias were assessed for eligibility. Among them, seven cases were excluded due to the presence of severe chordee (n = 3), proximal variant (n = 2), and recurrent cases of hypospadias (n = 2). Fifty cases were randomly divided into two groups using a 1:1 ratio (computer-generated randomization). Twenty-five cases were subjected to urethral advancement and glanuloplasty, and the rest were subjected to tubularized incised plate (TIP) urethroplasty. Results The mean age of all studied cases was 4.2 years. Approximately 52% had coronal or sub-coronal meatus, whereas 48% had glandular meatus. Both groups were matched according to age and meatus location (p > 0.05). No statistically significant difference was observed between the two groups regarding duration of operation, postoperative pain, and postoperative hospital stay. In addition, both groups did not differ significantly in late complications (meatal stenosis, meatal retraction, fistula, and glans dehiscence). Conclusions Both urethral advancement &glanuloplasty, and TIP urethroplasty have comparable short-term outcomes. Urethral advancement and glanuloplasty is preferred in certain conditions, especially in circumcised children or those with a narrow urethral plate. Trial registration The study protocol was approved by the Pan African Clinical Trials Registry (number for the registry is: PACTR202211757905870) on (29/11/2022). All procedures were performed per the Helsinki Declaration.
