Should transplant ureter be stented routinely or not?

Area of Science:

• Nephrology
• Urology
• Transplantation Surgery

Background:

• Renal transplantation is a life-saving procedure for end-stage renal disease.
• The use of double-J (DJ) stents in renal transplantation is a debated topic regarding its impact on early complications.
• Understanding the role of DJ stents is crucial for optimizing post-transplant outcomes.

Purpose of the Study:

• To compare the incidence of early complications in renal transplant recipients with and without double-J (DJ) stents.
• To evaluate the necessity of routine DJ stenting in all renal transplant patients.

Main Methods:

• A retrospective analysis of 194 renal transplant patients (2006-2013).
• Patients were divided into two groups: those who received a DJ stent and those who did not.
• Early complications including urinary tract infections, lymphocele, urinary leaks, wound infection, and perirenal hemorrhage were compared between groups.

Main Results:

• No significant difference in the overall rate of early complications was observed between the DJ stent group (101 patients) and the no-stent group (93 patients).
• Specific complication rates such as urinary tract infections, lymphocele, urinary leaks, wound infection, and perirenal hemorrhage showed no statistically significant variations between the two groups.
• Demographic data indicated mean ages of 46.5 ± 13.7 years for the stent group and 43.7 ± 12.6 years for the no-stent group, with comparable BMIs.

Conclusions:

• Routine prophylactic double-J (DJ) stenting is not indicated for all renal transplant patients.
• The prophylactic use of DJ stents does not appear to influence the occurrence of early complications after renal transplantation.
• Consideration for DJ stent use may be beneficial in specific patient subgroups, including obese individuals, those receiving cadaveric transplants, or transplants from unrelated donors.
