Summary
Nephrolithiasis (kidney stones) is rare after kidney transplants. Acute renal failure and anuria (no urine output) in transplant recipients may signal obstructive kidney stones.
Area of Science:
- Nephrology
- Transplant Surgery
- Urology
Background:
- Nephrolithiasis is uncommon in kidney transplant recipients.
- Anuria can be the sole presenting sign of complications in transplanted kidneys.
Observation:
- A 52-year-old male renal transplant recipient presented with acute renal failure and anuria.
- A palpable bulge over the graft and hydronephrosis were noted on examination and ultrasonography.
Findings:
- A diagnosis of obstructive acute renal failure secondary to nephrolithiasis was made.
- Successful management involved double-J ureteral stent insertion.
Implications:
- This case highlights the importance of considering obstructive nephrolithiasis in transplant recipients presenting with anuria.
- Early diagnosis and intervention, such as ureteral stenting, can resolve acute renal failure in this population.
