Outcomes after laparoscopic living donor nephrectomy: comparison of two laparoscopic surgeons with different levels of expertise.

To test the effect of surgeon experience on donor and recipient outcomes after laparoscopic living donor nephrectomy (LLDN). Results of a LLDN expert were compared with those of an LLDN novice. Between October 2008 and October 2010 the last 20 cases of a series of 130 consecutive LLDNs, performed by an expert (EXP) were compared with the first 20 cases of an LLDN novice (NOV). Donor and recipient outcomes were evaluated. The novice was mentored by the expert during his initial four LLDN cases. Donor and recipient demographics were not different between the two surgeon groups. Total operating time and warm ischaemia time during LLDN was significantly longer in the NOV group compared with the EXP group (273 min vs 147 min and 213 s vs 162 s, respectively). The incidence of donor complications was low in both groups. Length of hospital stay among donors did not differ between groups. Although delayed graft function, rejection rates and postoperative serum creatinine levels indicated slightly poorer recipient outcomes in the NOV group, differences did not reach statistical significance. Mentoring by an experienced urological laparoscopist may help an LLDN novice to generate acceptable donor and recipient outcomes. Whether or not prolonged operating times and warm ischaemia times during the early phase of an LLDN experience are risk factors for impaired graft function needs further evaluation.

Laparoscopic live-donor nephrectomy: a comparison with the open technique and how to reach quality standards: a single-center experience in Thailand.

We report our experience with laparoscopic donor nephrectomy (LDN) compared with open donor nephrectomy (ODN). Prognostic factors associated with adverse outcomes in LDN were identified. From January 2000 to December 2009, 243 consecutive live-donor nephrectomies were performed, including 129 LDNs and 114 ODNs. We compared patient demographics, perioperative outcomes, and recipient graft function in each group. Prognostic factors for adverse outcomes in LDN were investigated using uni- and multivariate analyses. Patient demographics, except mean donor age (P=.032), were similar between groups. Mean operative time (219 vs 163 minutes; P<.001) and warm ischemia time (WIT; 3.1 vs 1.7 minutes; P<.001) were significantly longer in LDN. Conversely, mean analgesic requirement (9.2 vs 14.7 mg morphine; P<.001) and postoperative hospital stay (6.5 vs 7.1 days; P=.003) were significantly lower with LDN. Mean estimated blood loss (EBL) was slightly lower in LDN (P=.15). There were 7 conversions from LDN to ODN. Complication rates were similar between the groups (P=.38). Delayed graft function (10.9% vs 1.7%; P=.016) and mean serum creatinine level at 1 month (1.47 vs 1.3 mg/dL; P=.04) were higher for LDN. However, 5-year allograft survival was not inferior among LDN (90% vs 85%; P=.42). Mean operative time (268 to 175 minutes; P<.001), EBL (316 to 66 mL; P<.001), and complication incidence (8 to 0 cases; P<.002) gradually decreased from the initial 43 cases to the last 43 cases of LDNs. Among surgeons who had performed-30 LDNs, the mean operative time and WIT were 197 mL and 2.8 minutes, respectively. Based on our evidence, LDN was a feasible and safe surgical option for live-donor nephrectomy, even in a small volume center. Better results can be achieved after a learning curve of experience for both the surgeon and the institution.

Comparison of laparoendoscopic single-site donor nephrectomy and conventional laparoscopic donor nephrectomy: donor and recipient outcomes.

To present a comparison of perioperative donor outcomes and recipient graft function in a series of patients undergoing laparoendoscopic single-site donor nephrectomy (LESS-DN) versus conventional laparoscopic donor nephrectomy (LDN). Data were collected for 50 consecutive LESS-DN patients and a matched cohort of 50 LDN patients. The donor outcomes analyzed included operative time, estimated blood loss, complications, visual analog pain scores, and recovery time. The recipient outcomes analyzed included serum creatinine at discharge and follow-up and the incidence of delayed graft function. The mean total operative time was shorter in the LDN group than in the LESS-DN group (P < .0001). Linear regression analysis of the LESS-DN operative times relative to case number showed a significant decrease in the operative time with increasing case number (r(2) = 0.19, P = .002). No statistically significant differences were found in estimated blood loss, warm ischemia time, length of stay, or visual analog pain scores between the 2 groups. However, the surgical incision was significantly smaller in the LESS-DN group (P < .0001). After discharge, the patient-reported time to complete recovery was faster in the LESS-DN group (P = .01). The incidence of complications was similar in both groups; however, major complications only occurred in the LDN group. No differences were found in the recipient serum creatinine values or the incidence of delayed graft function. Our initial experience with LESS-DN is encouraging. This retrospective matched-pair comparison between LESS-DN and LDN suggests that the single-port approach might be associated with quicker convalescence. Longer operative times in the LESS-DN group could simply represent the learning curve of a novel procedure.
