Buccal Mucosal Graft for the Repair of Iatrogenic Pelviureteric Junction Obstruction or Ureteric Stricture.
Buccal Mucosal Graft for the Repair of Iatrogenic Pelviureteric Junction Obstruction or Ureteric Stricture.
Prospective study to evaluate the safety and efficacy of using buccal mucosal graft for
 repairing complex cases of iatrogenic pelvi ureteric junction obstruction and long segment
 ureteric stricture disease.
A graft of buccal mucosa will be used to augment either the narrow unhealthy pelviureteric
 junction or a narrow long segment of the ureter.

 after freeing the narrowed part, a posterior incision will be made in the ureter or renal
 pelvis then the graft will be implanted on the psoas muscle using interrupted sutures in a
 position the allows easy anastomosis to the ureter or renal pelvis.

 Alternatively a lateral incision in the renal pelvis or the ureter may be done for the graft
 anastomosis and then surrounded with omenal flap to ensure a good blood supply for the graft.
Inclusion Criteria:

 - any patient with iatrogenic pelviureteric junction obstruction or long segment ureteric
 stricture

 Exclusion Criteria:

 -  elderly patients unfit for general anaesthesia.
