Is routine ureteric stenting needed in kidney transplantation? A randomized trial

Area of Science:

• Urology
• Transplantation Surgery
• Nephrology

Background:

• The necessity of routine ureteric stenting in kidney transplantation for low-risk patients remains unclear.
• Urological complications post-transplant can impact graft survival and patient outcomes.

Purpose of the Study:

• To determine if routine ureteric stenting reduces urological complications in kidney transplant recipients.
• To compare outcomes between routine stenting and selective stenting in low-risk kidney transplant patients.

Main Methods:

• A randomized controlled trial involving 280 kidney transplant recipients with normal lower urinary tracts.
• Patients were intraoperatively randomized to either routine ureteric stenting or selective stenting based on anastomosis technical difficulty.
• All participants underwent the Lich-Gregoire ureteroneocystostomy technique.

Main Results:

• No significant difference in the primary composite outcome of obstruction or leak between the routine stenting (3.5%) and no-routine-stenting (6.6%) groups (P=0.23).
• Selective stenting was performed in 4.4% of the no-routine-stenting group due to intraoperative technical concerns.
• All urological complications were managed effectively without significant morbidity; living donor organs and shorter ureteric length were risk factors for leaks.

Conclusions:

• Routine ureteric stenting is not indicated for kidney transplantation in patients identified as low-risk for urological complications.
• Judicious use of stenting for technically challenging anastomoses achieves comparable results to routine stenting, simplifying the procedure and potentially reducing resource utilization.
