Using cheek lining graft to repair a narrowed upper ureter
Part of Kidney & urinary clinical trials.
This trial studies using a graft taken from the inside of the cheek (buccal mucosal tissue) to repair a blockage in the upper part of the ureter or near the kidney (ureteropelvic junction). It may help people whose narrowing can’t be fixed with a simpler stitch technique.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a narrowing (stricture) in the upper ureter or a blockage near where the ureter meets the kidney (UPJO).
- Your condition cannot be treated with a primary stitch connection (primary anastomosis).
- You do not have an active infection in your mouth.
- You do not have mouth cancer of the lips, tongue, or cheeks.
- A study doctor confirms the cheek graft is medically safe for you.

This trial compares using skin from your penis versus tissue from inside your cheek to fix a long, tight scar in the front portion of your urinary tube (urethra). It may help if you have this scar and past attempts to widen the tube have failed.
This trial tests a new surgical method to repair a nearly closed bulbar urethral stricture (a narrowed part of the urine tube in the penis). This special technique uses tissue from the inside of your cheek to widen the tight spot.
This trial compares using a graft from the mouth or lip to treat a narrowed urethra in women. It aims to find which approach works better for improving urinary flow.
This study compares doing a graft in the first versus the second step of a two-stage urethral repair in men with a penile urethral narrowing. It uses oral lining tissue as the graft and aims to see which timing approach works best for healing and function.
This trial tests using a piece of your foreskin to repair a complex narrowing in your ureter (the tube between your kidney and bladder). It's for men who cannot have standard surgery and have extra foreskin available.
This study is testing a new way to use a small piece of your cheek tissue to repair the surface of your eye. It may help people with certain eye conditions, like recurring growths, tumors, or burns.
