Study summary

Placing the mouth-lining graft on the top or bottom of the urethra worked equally well

Graft placement review · Pooled studies · Published June 2025, BJU International

What was tested

A pooled look at studies comparing dorsal (top) and ventral (bottom) placement of a buccal mucosa graft, tissue from inside the cheek, in urethroplasty.

What they found

• Success rates were the same with either placement (relative risk 1.00).

What it means

Surgeons can choose the approach that suits the stricture; long-term success of cheek-graft urethroplasty is already high.
