Percutaneous stone and stent removal from renal transplants

Area of Science:

• Nephrology
• Urology
• Transplant Surgery

Background:

• Renal transplant recipients can develop complications such as stones, stent material, and blood clots within the collecting system.
• Management of these issues in transplanted kidneys requires careful consideration due to the unique anatomical and physiological context.

Observation:

• Traditional percutaneous nephrolithotomy (PCNL) techniques, developed for native kidneys, were adapted for use in renal allografts.
• These modified techniques were applied to address the removal of calculi, indwelling ureteral stents, and organized thrombi.

Findings:

• The study demonstrates that established percutaneous stone removal techniques can be safely and effectively utilized in the management of renal transplant collecting system obstructions.
• Modified percutaneous approaches successfully removed stones, stent fragments, and organized blood clots, indicating their versatility.

Implications:

• This approach offers a viable and safe minimally invasive option for managing collecting system pathology in renal transplant patients.
• Successful application of these techniques may improve outcomes and reduce morbidity associated with complications in the transplanted kidney.
