RESUMO
OBJECTIVES: This case report presents our experience regarding a horseshoe kidney from live donor to be used as a renal transplant. MATERIALS AND METHODS: The recipient was a 48-year-old man with chronic renal failure owing to hypertension who had been on hemodialysis for 2 years. The donor was his 43-year-old sister who had an uncomplicated horseshoe kidney with negative results on a urinalysis. An aortogram showed that the arterial supply to the kidney consisted of 2 superior arteries (1 on each side) and 1 inferior accessory artery that was divided to feed the lower fused parenchyma of the kidney. RESULTS: Surgery was performed via a retroperitoneal lumbotomy incision; the left half of the kidney was mobilized. The left kidney was procured by clamping the inferior accessory renal artery, transecting the parenchyma within the demarcation boundary. The transplant kidney was placed in the recipient's contralateral iliac fossa. The graft vein was anastomosed to the recipient's external iliac vein, the artery to the external iliac artery, and the ureter to the bladder. After perfusing the graft, no urine leakage was detected from the transacted surfaces, and the graft began producing urine. There were no complications after surgery. The patient was discharged on the 10th day after surgery with a creatinine level of 0.07 µmol/L. Maintenance immunosuppressive treatment included tacrolimus, mycophenolate mofetil, and prednisolone. CONCLUSIONS: We believe using a horseshoe kidney as a renal allograft after a detailed preoperative evaluation may help expand the donor pool.
