The outcome of kidney transplants with multiple renal arteries.

The use of grafts with multiple renal arteries has been considered a relative contraindication because of the increased incidence of vascular and urologic complications. The aim of this retrospective study is to determine whether the kidney grafts with multiple arteries have any adverse effect upon post transplant graft and patient survival. After reviewing the records of 35 adult kidney transplants done consecutively at Bangabandhu Sheik Mujib Medical University over a period of 3 years (Jan 2005 to Dec 2007). Mean age of recipients. 43.46±12.11 years and donors 40.33±11.46 years. Twenty patients (Group A) had grafts with single renal artery and 15 patients (Group B) had grafts with multiple renal arteries. The incidence of vascular complications, ureteral complications, post surgical haemorrhage, mean serum creatinine level and acute tubular necrosis in both Group A & B were observed. Complications developed in 15(43%) patients in this series. In Group A, 1(5%) developed post operative bleeding cause perinephric hematoma, 1(5%) technical obstruction of ureter, 1(5%) sloughed ureter, graft nephrectomy 1(5%) and acute tubular necrosis 1(5%) patient. In Group B, 2(13%) patients developed hematoma, urine leak 3(20%), sloughed ureter 1(6%), graft nephrectomy 1(6%) and acute tubular necrosis 3(20%) patients. Though the kidney grafts with multiple renal arteries have been considered a relative contraindication because of the increased risk of complication. In this series incidence of complication was 43%. The higher rate probably reflects the small number of living related donors.
