Abstract

Living-donor kidney transplantation is a well-established treatment of end-stage renal disease in Tunisia. Over the years, concerns have increased about the harmlessness of kidney donation. This longitudinal single center study was carried out to evaluate the safety of nephrectomy as well as further medical and surgical outcomes among donors. We collected and analyzed clinical, biological, biochemical and kidney size data at the time of nephrectomy and at M1, M3, M6, Y1, Y2, and Y4 after donation measured by ultrasound. All donor nephrectomies performed in the nephrology and transplantation unit of Sahloul Hospital of Sousse since October 2006 were included. Criteria of exclusion were lost to follow-up or lack of complete data. Of the 106 donors (66 females and 40 males), 92 donors were included in the follow-up analysis after following exclusion criteria. The mean age at the time of nephrectomy was 42.8 ± 10 years with the sex ratio 0.6. and 27% of our donors were mothers. Twenty-two percent of the donors were obese and 4% were hypertensive. The median initial glomerular filtration rate (GFR) was 105 mL/min/1.73 m2. The surgical approach was costal lumbotomy in 96% of cases and laparoscopy for four cases. The kidneys were removed from the left side in 93% of cases. Postoperative mortality was zero and early postoperative morbidity was low. The median duration of hospital stay was nine days. During follow-up, 14% attended all recommended visits. The median follow-up duration was 26 months. After two years post donation, the prevalence of HTN was 28% and obesity was 26%. The prevalence of GFR decline (50-59 mL/min) was 14% using formula by modification of diet in renal disease. None of our donors reached stage 4 or 5 CKD. Twelve had proteinuria and one donor had diabetes, a comparable prevalence of morbidities to the general population.
