Hand-assisted laparoscopic donor nephrectomy (HALDN) is widely performed to minimize burden on living kidney donors. However, hand port-site infections after HALDN may occur. This study aimed to assess the impact of donor characteristics including preoperative comorbidities and operative factors on hand port-site infection after HALDN.
In this single-center, retrospective cohort study, 1,260 consecutive HALDNs for living-donor kidney transplantation performed between January 2008 and December 2021 were evaluated. All living donors met the living kidney donor guidelines in Japan. Hand port-site infections were identified in 88 HALDN cases (7.0%). To investigate risk factors for hand port-site infection, donor characteristics including preoperative comorbidities such as hypertension, glucose intolerance, dyslipidemia, obesity, and operative factors such as operative duration, blood loss, preoperative antibiotic prophylaxis, and prophylactic subcutaneous suction drain placement at the hand port-site were analyzed using logistic regression analysis.
In the multivariate analysis, significant differences were identified regarding sex (P = 0.021; odds ratio [OR], 1.971; 95% confidence interval [CI], 1.108-3.507), preoperative antibiotic prophylaxis (P < 0.001; OR, 0.037; 95% CI [0.011-0.127]), and prophylactic subcutaneous suction drain placement at the hand port-site (P = 0.041; OR, 2.005; 95% CI [1.029-3.907]). However, a significant difference was not identified regarding glucose intolerance (P = 0.572; OR, 1.148; 95% CI [0.711-1.856]). Preoperative comorbidities may not cause hand port-site infections within the donors who meet the living kidney donor guidelines. Preoperative antibiotic prophylaxis is crucial in preventing hand port-site infection, whereas prophylactic subcutaneous suction drain placement may increase the risk of hand port-site infection.

OBJECTIVE: To access the current status of the security and feasibility of right kidney (RK) and multiple-renal artery (MRA) laparoscopic living donor nephrectomy (LLDN) which are more challenging compared to left kidney (LK) and single renal artery (SRA) because of a shorter renal vein and more complex vascular anatomy.
METHODS: We did a systematic review of the literature according to the PRISMA recommendations, reporting RK or MRA donor nephrectomy performed with a laparoscopic technique compared to LK or SRA kidney LLDN. The identified and analyzed primary outcomes of interest were operating time (OT), warm ischemia time (WIT), rate of conversion and transfusion, donor length of stay (LOS), delayed graft function (DGF) and rate of graft loss (GL).
RESULTS: 16 comparative studies (1397 cases) of RK-LLDN and 12 comparative studies including 15 series (993 cases) of MRA-LLDN were selected. For RK-LLDN review, conversion rate was 0.8% and blood transfusion rate 0.2%, only one case of graft venous thrombosis was reported, OT was shorter in four studies and there was no any difference of DGF and GL rate compared to LK-LLDN. For MRA-LLDN review, conversion rate was 1.3% and blood transfusion rate 1.1%, OT and WIT were longer compared to SRA-LLDN, there were more ureteral complications in two studies, and no difference in terms of vascular complications and graft loss rate.
CONCLUSIONS: RK-LLDN and MRA-LLDN would be similar to LK-LLDN and SRA-LLDN in terms of feasibility and safety for the donor as well as graft function results for RK-LLDN.

Background: Hand-assisted laparoscopic donor nephrectomy is a minimally invasive procedure for living kidney donation. The surgeon operative volume is associated with postoperative morbidity and mortality. We evaluated the risk factors associated with decreased renal function after hand-assisted laparoscopic donor nephrectomy performed by a single experienced surgeon. Methods: We included living renal donors who underwent hand-assisted laparoscopic donor nephrectomy by a single experienced surgeon between 2006 and 2013. Decreased renal function was defined as an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73 m2 on postoperative day 4. The donors were categorized into groups with postoperative eGFR < 60 mL/min/1.73 m2 or ≥ 60 mL/min/1.73 m2. Univariate and multivariate logistic regression analyses were performed to evaluate the risk factors associated with decreased renal function after hand-assisted laparoscopic donor nephrectomy. The hospital stay duration, intensive care unit admission rate, and eGFR at postoperative year 1 were evaluated. Results: Of 643 patients, 166 (25.8%) exhibited a postoperative eGFR of < 60 mL/min/1.73 m2. Multivariate logistic regression analysis demonstrated that the risk factors for decreased renal function were age [odds ratio (95% confidence interval), 1.062 (1.035-1.089), P < 0.001], male sex [odds ratio (95% confidence interval), 3.436 (2.123-5.561), P < 0.001], body mass index (BMI) [odds ratio (95% confidence interval), 1.093 (1.016-1.177), P = 0.018], and preoperative eGFR [odds ratio (95% confidence interval), 0.902 (0.881-0.924), P < 0.001]. There were no significant differences in postoperative hospital stay duration and intensive care unit admission rate between the two groups. In addition, 383 of 643 donors were analyzed at postoperative year 1. Sixty donors consisting of 14 (5.0%) from the group of 279 donors in eGFR ≥ 60 mL/min/1.73 m2, and 46 (44.2%) from the group of 104 donors in eGFR < 60 mL/min/1.73 m2 had eGFR < 60 mL/min/1.73 m2 at postoperative year 1 (P < 0.001). Conclusions: Increased age, male sex, higher BMI, and decreased preoperative eGFR were risk factors for decreased renal function after hand-assisted laparoscopic donor nephrectomy by a single experienced surgeon. These results provide important evidence for the safe perioperative management of living renal donors.
