Complications after a 5-year experience with laparoscopic donor nephrectomy: the Indiana University experience.

BACKGROUND: Laparoscopic donor nephrectomy (LDN) is becoming the standard of care for living donor nephrectomy. However, questions have been raised about the safety of LDN for the donor and about the potentially increased rates for ureteral complications experienced by the recipient. In this report, the authors review their 5-year experience with 253 living laparoscopic donor nephrectomies. METHODS: A retrospective chart review was performed for 253 laparoscopic live donors. Graft function and survival were compared using recipient postoperative creatinine values up to 12 months. RESULTS: The overall rate of complications in the investigated series was 10.3%. There were seven intraoperative complications (2.8%), three of which required open conversion. There were 19 postoperative complications (7.5%), three of which required reexploration for bleeding. The majority of complications were minor including 62% grade 1, 8% grade 2, 31% grade 3, and no grade 4 or 5 complications. There were no intraoperative complications in the right-sided donor group. There was a 5% complication rate for patients with a body mass index (BMI) exceeding 25. The findings showed that 11.2% of the recipients had slow graft function, and 4.4% had delayed graft function. Less than 1% of the recipients experienced ureteral stricture requiring permanent stent placement or reoperation. Overall, there was a 2% graft loss rate. CONCLUSIONS: The findings show a low rate of intraoperative and postoperative complications, most of which were minor complications. There was an increase in operative time and hospital stay in the right-sided group, but no increase in complication rate. There was no significant difference in outcome or complication rate for the overweight patients.

Laparoscopic donor nephrectomy: effects of learning curve on surgical outcomes.

UNLABELLED: Our objective was to determine the effect of an experienced laparoscopic surgeon's learning curve with laparoscopic donor nephrectomy (LDN) on patient outcome and graft function. MATERIALS AND METHODS: Retrospective review of the medical records of the initial 73 consecutive LDN patients and corresponding transplant recipients was performed. All of the LDN were performed by a single, experienced laparoscopic surgeon (C.P.S.). The method of LDN was slightly different between the groups. RESULTS: Patients were divided into early and late groups with 37 and 36 patients, respectively. There was no statistically significant difference in mean estimated blood loss (245 +/- 671.2 vs 84.7 +/- 63.9 mL), warm ischemia time (159.7 +/- 66.3 vs 150.8 +/- 63.0 seconds), postoperative creatinine levels (1.34 +/- 0.24 vs 1.29 +/- 0.26 mg/dL,), recipient mean creatinine level at 1 month (1.57 +/- .98 vs 1.53 +/- 0.46 mg/dL), and hospital stay (2.49 +/- 0.87 vs 2.47 +/- 0.56 days) between the early and late groups. However, the difference in mean operative time between early and late groups was statistically significant (255.2 +/- 42.4 vs. 209.1 +/- 30.8 minutes, P < .05). In addition, there were 8 (21.6%) vs 4 (11.1%) instances of slow graft function and 3 (8.1%) vs 0 instances of delayed graft function among the recipients in early group versus the late group. There were four (10.8%) vs two (5.6%) minor complications among donors of the early and late groups, respectively. CONCLUSION: There is a significant decrease in operating time and incidence of delayed graft function following the first 37 patients who underwent LDN by an experienced laparoscopist. Improvement in operative technique decreased operative time and improved perioperative graft function as evidenced by decreased slow graft function and delayed graft function in the late group.
