Transplantation of a horseshoe kidney from a living donor using stapler for transsection

Although it rather became a routine procedure to evaluate and use a cadaveric horseshoe kidney, using one from a living donor is quite rare. In this paper, we present methods we used during such a case which may benefit the procedures in the future. A 29-year-old female patient was considered for transplant and only viable living donor was her 59-year-old mother. Dynamic computed tomography revealed horseshoe anomaly with one renal artery and one renal vein for each side, a long but thin isthmus connecting lower poles with no visible arterial supply. Descending urography showed no connecting caliceal system. Donor nephrectomy was performed and isthmus separation was carried out with vascular stapler. Recipient was discharged on the 6th day with no complications. Patient was followed up for 6 months with normal creatinine levels. When properly assessed before the surgery, using a horseshoe kidney is not so challenging as thought.
