Laparoendoscopic Single-Site Plus One-Port Donor Nephrectomy: Analysis of 169 Cases

Testicular Pain Following Laparoscopic Donor Nephrectomy: An Underreported Complication

Introduction: Testicular pain (TP) after laparoscopic donor nephrectomy (LDN) is a relatively underreported complication. This study aimed to investigate the incidence, characteristics, and factors associated with ipsilateral TP after left-sided LDN. Materials and Methods: This study prospectively collected baseline data and surgical details for all patients who underwent left-sided LDN during the study period. Each patient underwent scrotal ultrasonography 1 month postoperation. Donors were categorized by the level of gonadal vein ligation (level 1 at the renal vein confluence and level 2 at or below the iliac vessel crossing) and the presence or absence of TP. The characteristics of pain and demographics were compared across the groups. Results: Among 61 male patients who underwent left-sided LDN between March 2017 and December 2018, 54.1% (33/61) experienced ipsilateral TP. TP was more frequent in level 2 donors (64.3%) than in level 1 (45.5%), but the difference was not statistically significant (p = 0.141). Most TP occurred within a week (60.6%), was mild (75.8%), and resolved within 3 months (63.7%). The incidence of varicocele and hydrocele was 32.8% and 34.4%, respectively. The occurrence of TP was not significantly associated with the presence of varicocele or hydrocele and other factors. Conclusion: More than half of the male donors who underwent LDN experienced TP. The findings emphasize the importance of discussing this potential complication during preoperative counseling. This study found no significant association between TP and the level of gonadal vein ligation or the presence of varicocele, warranting further investigation into the cause of TP.

Outcome of Kidney Transplantation With Transumbilical Laparoendoscopic Single-Site Donor Nephrectomy: A Single-Center Experience

AIM

The aim of this study is to present the outcome of kidney transplantation after laparoendoscopic single-site donor nephrectomy (LESS DN) compared with conventional laparoscopic donor nephrectomy (LDN) in a single-center experience.

METHODS

This retrospective study compares data from the initial experience with 110 consecutive LESS DN donors and their recipients (group A) with 205 consecutive conventional LDN donors and their recipients (group B).

RESULTS

This study compared 110 LESS DNs completed in an 18-month period with 205 LDNs completed in the immediately preceding 42-month period. All procedures were performed by the same surgeon. In groups A and B, respectively, the incidence of immediate graft function was 90% vs 91.2%, slow graft function was 9% vs 5.3%, delayed graft function was 0.9% vs 2.9%, graft loss was 0.9% vs 2.9%, and death with a functioning graft was 0.9% vs 1.5%. The mean serum creatinine levels were 1.3 ± 0.93 mg/dL vs 1.4 ± 1.2 mg/dL (P = .447), 1.1 ± 0.33 mg/dL vs 1.2 ± 0.75 mg/dL (P = .184), and 1.05 ± 0.25 mg/dL vs 1.1 ± 0.39 mg/dL (P = .224) at 7, 30, and 365 days after transplantation. The estimated glomerular filtration rate at 1 year was 88 ± 18.2 vs 83 ± 12.2 mL/min/1.73 m² (P = .004). The mean donor operative times in groups A and B were 175.9 ± 24.9 minutes vs 199.88 ± 37.06 minutes (P = .0001), respectively, and the mean warm ischemia time was 5.2 ± 1.02 minutes vs 3.64 ± 1.38 minutes, respectively (P = .0001). The mean body mass index, the incidence of complex vascular anatomy, and the rate of complications were the same in the 2 donor groups.

CONCLUSIONS

The outcome of kidney transplantation after LESS DN is comparable to conventional LDN. LESS DN can be employed as the primary approach for kidney donation with low donor risk and without compromising recipient outcomes.

Evolution of Laparoscopic Donor Nephrectomy Techniques and Outcomes: A Single-Center Experience with More than 1000 Cases

Background

Laparoscopic donor nephrectomy (LDN) has evolved and has been established as a surgical standard of care for kidney transplantation.

Material/Methods

This study retrospectively reviews 1132 patients who underwent 4 different laparoscopic living-donor nephrectomies: hand-assisted laparoscopic nephrectomy (HALDN), pure laparoscopic donor nephrectomy (PLDN), laparoendoscopic single-site plus 1-port donor nephrectomy (LESSOP-DN), and mini laparoscopic donor nephrectomy (MLDN).

Results

The mean estimated blood loss (EBL) for the HALDN group was meaningfully higher than those of LESSOP-DN and MLDN (57.5±52.2 mL versus 21.0±30.0 mL versus 18.2±28.7 mL) (P<0.001). The EBL for PLDN (53.3±35.3 mL) was also significantly higher than those of LESSOP-DN and MLDN (P<0.001). Length of stay (LOS) for HALDN was longer than that for LESSOP-DN (4.2±1.2 day versus 4.0±1.4 days, P=0.002). There was 1 intraoperative open conversion in the HALDN group and 2 HALDN surgeries that required postoperative exploratory laparotomy. LESSOP-DN had 3 (0.8%) postoperative incisional hernias. For recipients, the results revealed no significant differences between all 4 groups in terms of estimated glomerular filtration rate (eGFR) and the 1-year graft failure rate.

Conclusions

The LESSOP-DN group was associated with a shorter incision length than those of HALDN and PLDN and shorter LOS than that of HALDN. Recipient results showed no meaningful difference regarding laparoscopic donor nephrectomy technique.

Acupuncture in living liver and kidney donors: a feasibility study

OBJECTIVE

The purpose of this study was to test the feasibility of integrating acupuncture into the routine care of living liver and kidney donors during the process of donation and recovery.

METHODS

This is a pilot study on the feasibility of a brief acupuncture intervention for living liver and kidney donors. Participants received acupuncture immediately prior to organ donation surgery, every day as inpatients, while recovering from donation, and at a 2-week follow-up. Prior to surgery, questionnaires were completed on acupuncture outcome expectations and the State-Trait Anxiety Inventory. After participating, those who received acupuncture provided feedback. Following the active intervention, a retrospective chart review was conducted, using donors who did not receive acupuncture as a comparison cohort.

RESULTS

Forty donor candidates were approached and recruited, 32 consented and ultimately 25 donors participated in the acupuncture intervention (15 of kidney, 10 of liver), 68% female, and 88% Caucasian; only one had prior experience with acupuncture. Participants received an average of 4 sessions while inpatient (range 2-8). Those who expected acupuncture to be more helpful prior to the intervention reported lower inpatient pain scores (P = 0.04). Qualitative feedback from patients was predominantly positive, indicating acupuncture was helpful for relaxation and pain. However, a few patients reported feeling overburdened during postdonation recovery, and that the study was viewed as additional obligation.

CONCLUSION

Preliminary findings suggest it is feasible to integrate acupuncture into inpatient recovery for living organ donation. Tailoring interventions to the specific needs of patients is important to address ongoing concerns. Larger studies are needed to further ascertain benefits of peri-operative acupuncture.

A randomized, prospective study of laparoendoscopic single-site plus one-port versus mini laparoscopic technique for live donor nephrectomy

PURPOSE

To compare the clinical outcomes of laparoendoscopic single-site plus one-port donor nephrectomy (LESSOP-DN) and mini laparoscopic donor nephrectomy (MLDN).

METHODS

A prospective randomized controlled trial was conducted from December 2014 to February 2016 in donors scheduled for left donor nephrectomy. Donor and recipient demographics and clinical outcomes including pain scores and questionnaires (BIQ: body image questionnaire, SF-36, patient-reported overall convalescence) were also compared.

RESULTS

A total of 121 eligible donors were recruited, of which 99 donors who were scheduled to undergo an operation on their left side were randomized into LESSOP-DN (n = 50) and MLDN (n = 49) groups. There were no significant demographic differences between the two groups. The renal extraction time in the LESS-DN group was shorter than that in the MLDN group (75.89 ± 13.01 vs. 87.31 ± 11.38 min, p < 0.001). Other perioperative parameters and complication rates were comparable between the two groups. The LESSOP-DN group had a smaller incision length than the MLDN group (4.89 ± 0.68 vs. 6.21 ± 1.11 cm, p < 0.001), but cosmetic scores and body image scores were similar in the two groups (p = 0.905, 0.217). Donor quality of life (SF-36) and recovery and satisfaction data were comparable between the two groups. Delayed graft function (DGF) occurred in one recipient undergoing MLDN procedure (2.1%) and progressed to graft failure.

CONCLUSIONS

There were no differences in cosmetic satisfaction between groups despite the smaller incision size of LESSOP-DN. Safety parameters and subjective measures of postoperative morbidity were similar between the two groups.

Perioperative Events and Complications in Minimally Invasive Live Donor Nephrectomy: A Systematic Review and Meta-Analysis

BACKGROUND

Minimally invasive live donor nephrectomy has become a fully implemented and accepted procedure. Donors have to be well educated about all risks and details during the informed consent process. For this to be successful, more information regarding short-term outcome is necessary.

METHODS

A literature search was performed; all studies discussing short-term complications after minimally invasive live donor nephrectomy were included. Outcomes evaluated were intraoperative and postoperative complications, conversions, operative and warm ischemia times, blood loss, length of hospital stay, pain score, convalescence, quality of life, and costs.

RESULTS

One hundred ninety articles were included in the systematic review, 41 in the meta-analysis. Conversion rate was 1.1%. Intraoperative complication rate was 2.3%, mainly bleeding (1.5%). Postoperative complications occurred in 7.3% of donors, including infectious complications (2.6%), of which mainly wound infection (1.6%) and bleeding (1.0%). Reported mortality rate was 0.01%. All minimally invasive techniques were comparable with regard to complication or conversion rate.

CONCLUSIONS

The used techniques for minimally invasive live donor nephrectomy are safe and associated with low complication rates and minimal risk of mortality. These data may be helpful to develop a standardized, donor-tailored informed consent procedure for live donor nephrectomy.
