Laparoscopic donor nephrectomy

Background: Kidney transplantation is a definitive treatment of end‐stage renal disease. Laparoscopic donor nephrectomy (LDN) has been widely accepted around the world since its introduction in 1995 as a minimum invasive procedure. We report our clinical experience of 141 consecutive LDNs performed in two tertiary hospitals in Western Australia. Methods: From December 2000 (Royal Perth Hospital) and January 2005 (Sir Charles Gairdner Hospital) to January 2009, 141 LDNs were performed in two tertiary hospitals by four urologists. All donors underwent rigorous work‐up prior to surgery. Donor age ranged from 23 years to 81 years (49.85 ± 11.30 years). The male to female ratio was 1 to 1.3. Donor body mass index (BMI) was 26.77 ± 4.31, and glomerular filtration rate was 96.25 ± 12.33 mL/min/1.73 sqm. The laparoscopic technique was transperitoneal approach exclusively. Results: All LDNs were performed successfully without hand a ssistance. The warm ischaemic time ranged from 3 to 11 min. The hospital stay was 4.16 ± 1.30 days. The overall complication rate was 17.0%, with three major complications (2.1%): a splenetic infarction, a chylous ascites and a pulmonary embolism occurred. Donors' demographic data (age, sex, BMI, side of surgery) did not show a statistically significant association with surgical complications. Conclusions: Transperitoneal laparoscopic live donor nephrectomy is a safe and effective procedure. Combined use of vascular stapler and Hem‐o‐Lok is very important for management of the renal artery stump. It is our current practice to administer anticoagulants during and post‐surgery for at least 2 weeks.     

Laparoscopic donor nephrectomy

Since it first was performed in 1995, laparoscopic donor nephrectomy (LDN) has grown to be the standard of care in most transplant centers in the United States. This article reviews the current indications, selection criteria, surgical approaches, outcomes, and complications of LDN.     

Laparoscopic donor nephrectomy

Live donor renal transplantation provides significant advantages when compared with cadaveric renal transplantation. Unfortunately, there are disincentives associated with donation including prolonged hospitalization, significant postoperative pain, and prolonged convalescence. With the advent of laparoscopic donor nephrectomy, there has been an increase in live donation at centers performing the procedure secondary. Incentives provided by laparoscopic donation include a reduction in hospital stay, less postoperative analgesic requirements, and an earlier return to normal daily activities. Most importantly, graft function and survival are equivalent to open live donation. Laparoscopic donor nephrectomy is evolving to become the preferred method of procuring living donor kidneys.

Background Several large series of laparoscopic donor nephrectomy (LDN) have been published, largely focusing on immediate results and short-term complications. The aim of this study was to examine the results of LDN and collect medium-term and long-term donor followup. Methods We examined the results of two surgeons who performed 500 consecutive LDNs from 1996 to 2005. Prospective databases were reviewed for both donors and recipients to record demographics, medical history, intraoperative events, and complications. Patients were followed between 1 month and 9 years after surgery to assess for delayed complications, especially hypertension, renal insufficiency, incisional hernia, bowel obstruction, and chronic pain. Results Left kidneys were procured in 86.2% of cases. Mean operative time was 3.5 h, and warm ischemia time averaged 3.4 min. Hand-assistance was used in 13.8%, and conversion rate was 1.8%. Intraoperative complication rate was 5.8% and was predominantly bleeding (93.1%). Most (86.2%) of the operative complications occurred during the initial 150 cases of a surgeon, compared with 10.3% in the subsequent 150 cases (p = 0.003). Operative time decreased by 87 min after the initial 150 cases (p < 0.001). Immediate graft survival was 97.5%. Delayed graft function occurred in 3.0% of recipients, and acute tubular necrosis occurred in 7.0%. Thirty-day donor complication rate was 9.8%. Mean donor creatinine was 1.24 on the first postoperative day, 1.27 at 2 weeks, and 1.24 at 1 year. At a mean followup of 32.8 months, long-term donor complications consisted of 11 cases of hypertension, 9 cases of prolonged pain or paresthesia, 2 incisional hernias, 1 small bowel obstruction requiring laparoscopic lysis of adhesions, and 1 hydrocele requiring repair. Conclusions LDN can be performed with acceptable immediate morbidity and excellent graft function. Operative time and complications decreased significantly after a surgeon performed 150 cases. Long-term complications were uncommon but included a likely underestimated incidence of hypertension.     

Laparoscopic donor nephrectomy

BACKGROUND: Living kidney donation represents an important source of organs for patients with end-stage renal failure. Over the past decade, laparoscopic donor nephrectomy has replaced the conventional open procedure in many transplant centres. Using evidence-based methods, this study examines the current status of laparoscopic donor nephrectomy. METHOD: A Medline literature search (PubMed database, 1999-2002) and manual cross-referencing were performed to identify all articles relating to laparoscopic donor nephrectomy. Safety and efficacy criteria were analysed systematically for each study. Studies included were categorized using an evidence-based level grading system. RESULTS: Of 687 publications, 20 studies with level I-II evidence and 12 with level III evidence were analysed. Only one level I study could be identified. Level I and level II evidence suggests superiority of the laparoscopic approach in regard to postoperative analgesic consumption, hospital stay and return to work. Other safety and efficacy criteria, including donor and recipient outcomes, were similar between the two techniques. CONCLUSION: Laparoscopic donor nephrectomy has gained community acceptance by physicians and patients over the past decade. Despite a lack of strong evidence, such as large prospective randomized studies, laparoscopic donor nephrectomy is likely to become the 'gold standard' for donor nephrectomy in the near future.

Laparoscopic right donor nephrectomy

BACKGROUND: Laparoscopic donor nephrectomy (LDN) preferentially involves the left kidney to optimize vessel length, but occasionally, right nephrectomy is preferred. Right LDN differs markedly in anatomic relations and the need for a fourth port. This retrospective study compares donor outcomes and graft function of right and left LDN and describes the technique. METHODS: Consecutive patients undergoing right LDN from March 26, 1996 to December 31, 2000 were compared with those undergoing left LDN. Age, height, weight, body mass index, creatinine, creatinine clearance, operative time, warm ischemia time, analgesic requirements, serial postoperative creatinine, time to diet resumption, and hospital stay were compared. A second cohort matched for age, gender, race, and temporal left LDN also were compared with the group undergoing right LDN. RESULTS: No significant differences were found for any of the parameters measured. CONCLUSION: This study demonstrates that despite substantial differences in the procedures, donor outcome and graft survival are similar for right and left LDN.     

Laparoscopic live donor nephrectomy

Laparoscopic donor nephrectomy offers numerous advantages when compared with the traditional open approach. For the donor, it has resulted in a shorter hospital stay, fewer postoperative analgesic requirements, earlier return to activities of daily living and employment, and decreased financial loss owing to absence from the workforce. For the recipient, the procedure does not adversely impact on allograft function, graft survival, or patient survival.     

Laparoscopic live donor nephrectomy

Live donor renal transplantation has many advantages including greater graft and patient survival, shorter waiting periods, improved human leukocyte antigen matching, and less cold ischemia. Until recently, disincentives from the operation, such as prolonged hospitalization, postoperative pain, and significant convalescence, have deterred live donor renal transplantation. This article describes the technique of laparoscopic live donor nephrectomy and briefly reports the results. The procedure has resulted in improved postoperative recovery and shorter convalescence, with no effect on recipient renal function.     

Laparoscopic live donor nephrectomy

BACKGROUND: The demand for renal transplants is greater than the available kidneys. Live donation is one way of increasing the supply. Laparoscopic removal of the donor kidney appears to reduce morbidity for the donors. Some who are hesitant because of the morbidity associated with open nephrectomy are willing to consider the laparoscopic donor nephrectomy. METHODS: Laparoscopic donor nephrectomy was offered to all but three donors since the commencement of the programme in 1997. Data were collected both prospectively and retrospectively for the first 120 donors. Venous and arterial anatomy was assessed preoperatively by computed tomographic angiography. RESULTS: All but four donor procedures were completed laparoscopically. Three of these were for bleeding that could not be safely controlled laparoscopically and the fourth was a planned conversion to deal with the renal vessels, in the first right nephrectomy. Two kidneys were lost due to arterial thrombosis and two underwent segmental infarction after the loss of one of two or three separately anastomosed vessels. Three recipients had delayed function and two of them required dialysis postoperatively. Other minor complications occurred but were uncommon. CONCLUSIONS: Laparoscopic live donor nephrectomy is safe for the donor and the transplant kidney. It offers the advantage of decreased morbidity for the donor, with a shorter hospital stay, earlier return to normal activity and, for some, early return to work.
