Stones in renal transplants

Summary
Kidney stones can form in functioning renal transplants, often linked to high serum calcium levels. Conservative treatment to lower calcium is recommended before considering parathyroid surgery.
Area of Science:
- Nephrology
- Transplant Surgery
- Endocrinology
Background:
- Renal transplant recipients can develop kidney stones.
- Stones in transplanted kidneys may be associated with hypercalcemia.
Observation:
- Two cases of functioning renal transplants with stone formation are presented.
- Patients exhibited elevated serum calcium (3.00 mmol/l and 2.65 mmol/l) and one had increased parathyroid hormone.
- Subtotal parathyroidectomy was performed in both cases.
Findings:
- Stone recurrence was noted in one patient post-parathyroidectomy.
- Conservative measures to reduce serum calcium are suggested for mild hypercalcemia without renal function decline.
Implications:
- Highlights the importance of managing hypercalcemia in renal transplant recipients.
- Suggests a stepwise approach to treatment, prioritizing conservative methods before surgical intervention for transplant kidney stones.
