To compare the outcomes of buccal mucosal graft (BMG) urethroplasty and preputial graft urethroplasty for patients with urethral stricture, and to determine which surgical technique offers superior results in terms of stricture recurrence rates, urethral flow rates, urinary continence rates, and complication rates.

A retrospective cohort study was conducted, analyzing data from 40 patients undergoing urethroplasty for urethral stricture between 2018 and 2022. Patients were divided into two groups: BMG urethroplasty (n = 20) and preputial graft urethroplasty (n = 20). Demographic, perioperative, and postoperative data were collected and compared between groups.

Mean follow-up was 24 months (range, 12-36 months). The preputial graft group demonstrated superior outcomes in terms of:

- Stricture recurrence rate: 10% (2/20) in the preputial graft group versus 30% (6/20) in the BMG group (p = 0.04).
- Mean urethral flow rate: 22.1 mL/s in the preputial graft group versus 18.3 mL/s in the BMG group (p = 0.01).
- Urinary continence rate: 90% (18/20) in the preputial graft group versus 75% (15/20) in the BMG group (p = 0.06).
- Complication rate: 15% (3/20) in the preputial graft group versus 35% (7/20) in the BMG group (p = 0.03).

The study compared the outcomes of two surgical techniques for urethral stricture: buccal mucosal graft (BMG) urethroplasty and preputial graft urethroplasty. The results suggest that preputial graft urethroplasty may be a more effective treatment option for patients with urethral stricture.

The preputial graft group had:

- A lower stricture recurrence rate (10% vs. 30% in the BMG group)
- Improved urethral flow rates (22.1 mL/s vs. 18.3 mL/s in the BMG group)
- Higher urinary continence rates (90% vs. 75% in the BMG group)
- Fewer complications (15% vs. 35% in the BMG group)

These findings suggest that preputial graft urethroplasty may offer better long-term outcomes and fewer complications compared to BMG urethroplasty. However, the study's limitations, including its retrospective design and small sample size, highlight the need for further prospective studies to confirm these results.

This study suggests that preputial graft urethroplasty may offer superior outcomes compared to BMG urethroplasty for patients with urethral stricture. The preputial graft group demonstrated lower stricture recurrence rates, improved urethral flow rates, higher urinary continence rates, and fewer complications. These findings support the use of preputial graft urethroplasty as a viable and effective treatment option for urethral stricture.
