Combined ureterocalicostomy with buccal mucosa graft ureteroplasty in complex upper ureteral stricture: A rare case of reconstruction

Abstract

The treatment of a major and complex ureteric stricture requires the use of a bowel interposition or autotransplantation of the kidney, which is a major undertaking and remains the traditional option. Buccal mucosa is an established tissue for urethral reconstruction and can be used safely for the repair of narrowing of the ureter. This technique has been well documented in the literature; however, a combined ureterocalicostomy with buccal mucosa graft ureteroplasty has not yet been reported in literature. We report the case of a 59-year-old female who was diabetic and hypertensive presented with a long-length, complex upper ureteric stricture with recurrent pyelonephritis. A long stricture in the upper ureter measuring approximately 8 cm was successfully repaired by free buccal mucosal onlay patch graft over a double J stent with ureterocalicostomy. This technique can be used in salvaging kidneys with complex ureteric strictures along with fibrotic pelvis.
