[Surgical view of a series of 3,000 kidney transplantations]

Area of Science:

• Nephrology
• Transplant Surgery
• Urology

Context:

• Review of 3,000 consecutive kidney transplantations to assess complication rates and outcomes.
• Analysis of vascular and urinary complications, including thrombosis, stenosis, and fistulas.
• Evaluation of surgical modifications and device usage (e.g., JJ-stents) in mitigating complications.

Purpose:

• To analyze the incidence and management of vascular and urinary complications in a large series of kidney transplantations.
• To identify factors influencing complication rates, such as surgical techniques and ischemia time.
• To evaluate the effectiveness of different treatment strategies for post-transplant complications.

Summary:

• Vascular complications occurred in 7.4% and urinary complications in 9.8% of kidney transplant recipients.
• Specific surgical approaches (e.g., external iliac artery implantation, vena cava extension) reduced arterial stenosis.
• Use of JJ-stents decreased urinary fistula incidence, though urinary stenosis remained a concern. Both surgical and endoscopic treatments for renal artery stenosis showed high success rates (82%).
• Endourological treatment success rates were 64% for fistulas and 46% for stenoses.
• Optimizing organ harvest and reducing cold ischemia time are crucial for prompt graft function recovery.

Impact:

• Demonstrates the impact of surgical technique refinement on reducing kidney transplant complications.
• Highlights the efficacy of JJ-stents in managing urinary fistulas.
• Provides evidence for the success of interventional procedures in treating post-transplant vascular and urinary issues.
• Emphasizes the critical role of organ procurement and preservation in achieving optimal transplant outcomes.
