Change in renal function following laparoscopic donor nephrectomy using 99 mTc-diethylenetriaminepentaacetic acid scan

Purpose We assessed the change in remaining kidney function after laparoscopic donor nephrectomy using serial technetium 99m diethylenetriaminepentaacetic acid (DTPA) scans and investigated the factors affecting the course. Methods Data from 155 donors were obtained from a prospectively maintained database. All donors underwent consecutive DTPA scans preoperatively and 1 month, 6 months and 1 year postoperatively. We investigated the longitudinal change in renal function after surgery and analyzed parameters to influence the perioperative glomerular filtration rate (GFR) change. Results The changes in GFR according to the DTPA scan presented significant improvement from 1 month up to 2 years after donation (all p
