The aim of this study was to evaluate the long-term medical risks of living-related donors in our center.
PATIENTS AND METHODS:
185 living-related donors participated in the study. The factors assessed were creatinine clearance rate (CrCl), serum creatinine (SCr), BUN, hematocrit levels, proteinuria, microalbuminuria and hypertension rates, and renal parenchyma thickness and kidney dimensions predonation as well as at the last follow-up. In addition, we examined postoperative complications. A lombotomy incision was the choice for donor nephrectomy procedure routinely.
The mean length of hospital stay after donor nephrectomy was 3.2 +/- 0.6 days (range, 2-5 days). Seven donors readmitted during the first month after operation with surgical site infection were treated successfully. Four donors were reoperated for incisional hernia repairs and discharged without complication. The mean follow-up period was 61.6 +/- 50.4 months (range, 2-180 months). Mean ages of the donors at operation and at the last follow-up were 50.9 +/- 12.7 years (range, 20-81 years) and 56.5 +/- 11.9 years (range, 29-77 years), respectively. The male-to-female ratio was 0.69. Mean SCr levels and CrCl rates predonation and at the last follow-up were 0.83 +/- 0.22 mg/dL versus 1.1 +/- 0.2 mg/dL (P < .001), and 103.9 +/- 28.8 mL/min versus 88.3 +/- 25.9 mL/min (P = .03), respectively. SCr levels were within normal limits in all donors at predonation and at the last follow-up. At the last follow-up, CrCl was also within expected normal limits in all donors. Hypertension was detected in 13 donors. Mean predonation and at the last follow-up renal parenchymal thickness, BUN, and hematocrit levels were similar. Kidney dimensions were significantly different at the last follow-up after donation (P = .001). Eleven donors displayed proteinuria and 19 had microalbuminuria at the last follow-up, which had been negative for all donors predonation. There were seven surgical site infections and 4 incisional herniae.
Donor nephrectomy was performed with low surgical morbidity and comparable results of clinical and laboratory data to the age-matched general population.
