About this study
Official title: Penile Skin Versus Buccal Mucosal Graft in Augmentation Urethroplasty for Long Anterior Urethral Stricture: A Prospective Randomized Study
The aim of this study is to analyze the outcomes of dorsal onlay buccal mucosal graft (BMG) and penile skin graft (PSG) urethroplasty in the management of long segment bulbar urethral stricture.
Read the detailed description
Penile urethral reconstruction proves to be a continuous challenge as no perfect technique is considered for all patients with this problem. Among all the methods used for treatment of urethral stricture, the substitution urethroplasty with tissue transfer using either flap or graft is the gold standard treatment option for long segment urethral strictures.
In 1993, McAninch described a circular fasciocutaneous flap for the management of penile urethral stricture up to 15 cm that showed excellent cosmetic and functional outcomes due to this being a hairless, flexible flap with a rich vascular supply.
Buccal mucosal graft (BMG) was rediscovered and popularized in 1992 by Burger et al., then El-Kassaby et al. in 1993 published a series using buccal mucosal graft to repair anterior urethral stricture. Buccal mucosal graft became an ideal urethral substitute due to easy harvesting, hairlessness and compatibility in a wet environment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Buccal Mucosal Graft (BMG) UrethroplastyProcedure or surgery
Also called Dorsal onlay buccal mucosal graft
Urethroplasty using a buccal mucosal graft harvested from the inner cheek. The graft is dorsally onlaid to reconstruct the strictured urethral segment. The procedure is conducted under spinal or general anesthesia.
Penile Skin Graft (PSG) UrethroplastyProcedure or surgery
Also called Dorsal onlay penile skin graft
Urethroplasty using a penile skin graft harvested from the ventral surface of the penis. The graft is applied dorsally after excision of the fibrotic urethral segment. The surgery is performed under spinal or general anesthesia.
| Study group | Role | What they receive |
|---|---|---|
| Buccal Mucosal Graft (BMG) | Experimental | Participants will undergo dorsal onlay augmentation urethroplasty using a buccal mucosal graft harvested from the inner cheek. The procedure is performed under spinal or general anesthesia. Graft is sutured dorsally over the strictured urethral segment after excision of the fibrotic tissue. Receives: Procedure: Buccal Mucosal Graft (BMG) Urethroplasty |
| Penile Skin Graft (PSG) | Experimental | Participants will undergo dorsal onlay augmentation urethroplasty using a penile skin graft harvested from the ventral surface of the penis. The hairless skin is prepared and sutured dorsally over the strictured urethral segment. The procedure is done under spinal or general anesthesia. Receives: Procedure: Penile Skin Graft (PSG) Urethroplasty |
What is being measured
The primary outcome is the main question the study is designed to answer.
Surgical Success Rate
Success is defined as satisfactory urinary stream with no need for further intervention (such as dilatation or DVIU) and no evidence of stricture on retrograde urethrogram during follow-up.
Measured: 9 months postoperatively
Secondary outcomes (3)
International Prostate Symptom Score (IPSS)
Evaluation of changes in urinary symptoms using International Prostate Symptom Score (IPSS) to assess functional outcome and patient comfort after urethroplasty will be assessed.
Measured: 9 months postoperatively
Length of Urethral Stricture
Length of Urethral Stricture will be measured to compare the characteristics of strictures managed by each graft technique.
Measured: Intraoperatively
Postoperative Complications
Complications such as infection, bleeding, graft failure, and fistula formation following surgery will be recorded.
Measured: 9 months postoperatively
