Successful en bloc transplantation of a horseshoe kidney without division of the isthmus: first case reported in South Africa

Abstract

This case is the first report of an en bloc transplantation of a horseshoe kidney in South Africa. The graft anatomy included complete fusion of the lower poles of the two kidney units with a single artery and vein associated with each unit. The thick isthmus of the graft kidney was supplied by a single, large caliber anomalous artery. Bench work (total duration 160 minutes) included the preparation of a short segment of donor aorta and IVC (containing the renal vessels) which were anastomosed to the recipient common iliac artery and common iliac vein respectively. The artery of the isthmus was anastomosed to the recipient right internal iliac artery. The graft was placed intraperitoneally. Cold ischaemia time was 15 hours, warm ischaemia time 144 minutes, total procedure time 450 minutes and estimated blood loss 1100 ml. Renogram (^99mTc MAG-3) on days 1, 3 and 14 postoperatively revealed ATN. Hospital stay was 17 days and nadir creatinine at 6 weeks was 77 μmol/l.
