[Renal transplant calculi in a renal allograft treated with extracorporeal shock wave lithotripsy in a patient with persistent hyperparathyroidism: a case report].

Between 1984 and 1991, six of 105 renal transplant recipients at our institution formed urinary tract calculi after transplantation (5.7%). In these 6 patients, one case of nephrolithiasis in a transplanted kidney was treated with extracorporeal shock wave lithotripsy (ESWL). A 37-year-old woman underwent cadaveric renal transplantation twenty months before, and her renal function remained stable. However calculi in the transplanted kidney and bladder were formed and ESWL was used for the treatment of the renal calculus in the transplanted kidney. She was discharged from the hospital two weeks postoperatively while passing small gravel in the urine after successful fragmentation of the calculus without any major complications. As follow-up KUB film two weeks later demonstrated that all stone fragments had been passed, but she was treated again by ESWL four months later because IVP films four weeks later revealed recurrent calculi in the transplanted kidney. The stones were fragmented successfully and spontaneously passed with voiding. Moreover we performed total parathyroidectomy with autotransplantation for persistent hyperparathyroidism, with subsequent good clinical results.
