Namasivayam S, Kalra MK, Waldrop SM, Mittal PK, Small WC. Multidetector row CT angiography of living related renal donors: is there a need for venous phase imaging? Eur J Radiol 2006; 59:442-52. [PMID: 16621395 DOI: 10.1016/j.ejrad.2006.03.018] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2005] [Revised: 03/07/2006] [Accepted: 03/15/2006] [Indexed: 11/15/2022]
Abstract
OBJECTIVE To prospectively evaluate whether renal venous anatomy can be detected from arterial phase images of multidetector row CT (MDCT) of renal donors. MATERIAL AND METHODS Institutional review board approved our study protocol with waiver of consent. Forty-eight consecutive renal donors (age range, 21-56 years; M:F, 20:28) referred for MDCT evaluation were included. Two sub-specialty radiologists performed an independent and separate evaluation of renal venous anatomy in arterial and venous phase images. Opacification of renal venous structures was scored on a five-point scale (1-not seen; 3-minimal opacification; 5-excellent opacification). Arterial and venous phase opacification scores were compared by Wilcoxon signed rank test. RESULTS Both readers detected all renal venous anomalies in arterial as well as venous phase images. Each reader detected accessory right renal veins (n=14), retroaortic left renal vein (n=2), circumaortic left renal vein (n=1), and left renal hilar arteriovenous malformation (n=1) in arterial phase images. Retroaortic left renal venous branch was difficult to differentiate from lumbar vein (reader-1, n=1; reader-2, n=2) in both arterial and venous phase images. Sensitivity of detection of renal veins, left adrenal, gonadal and lumbar veins in arterial phase images was 100, 83-88, 100, and 85-90%, respectively. As expected, venous phase images showed significantly greater opacification of renal veins, left gonadal, adrenal and lumbar veins (p<.05). However, this did not substantially limit the evaluation of renal venous anatomy in arterial phase images. Both readers had substantial interobserver agreement (kappa coefficient, 0.7; p<0.05). CONCLUSIONS Arterial phase MDCT images alone can be used to detect renal venous anomalies, and to identify small left renal venous branches namely, the left gonadal, adrenal and lumbar veins in renal donors. Venous phase MDCT acquisition is not necessary for evaluation of renal venous anatomy in renal donors.

Abstract
BACKGROUND Despite the many benefits of living donor kidney transplantation, economic consequences can result for donors. We reviewed studies which quantified the direct and indirect costs incurred by living kidney donors, in order to understand the strengths and limitations of existing literature. METHODS We identified relevant studies in MEDLINE, EMBASE and ECONOLIT bibliographic databases, in the Science Citation Index and study reference lists. Any study which reported at least one cost relevant to donors was included. The accuracy of abstracted data was verified by two reviewers and reported in year 2004 US dollars. RESULTS Thirty-five studies from 12 countries described costs incurred by individuals who donated between the years 1964 and 2003. No study comprehensively quantified all relevant expenses-the sum of select costs considered in one US study averaged Dollars 837 per donor and ranged from Dollars 0 to 28,906. Travel and/or accommodation costs were incurred by 9-99% of donors, and were higher in countries with a larger land mass. Post-discharge analgesics were required by 4-24% of donors, but prescription costs were not reported. Between 14 and 30% of donors incurred costs for lost income, with an average loss of Dollars 3386 in one study from the UK and Dollars 682 in another study from the Netherlands. Costs for dependent care were incurred by 9-44% of donors, while costs for domestic help were incurred by 8% of donors. CONCLUSIONS Donors incur many types of costs attributable to kidney donation and the total costs are certainly higher than previously reported. To guide informed consent and fair reimbursement policies, further data on all relevant costs, preferably from a detailed prospective multi-centre cohort study, are required.

Abstract
BACKGROUND Free radicals induced by several diseases can trigger oxidative stress, leading to the production of malondialdehyde (MDA) and protein carbonyl content (CB). Volatile agents are able to increase the extent of oxidative status. However, the effects of these agents together with pneumoperitonium (Pp) have not been reported. We aimed to investigate the role of volatile anesthetics and ischemic injury during Pp on free radicals and scavenging enzymes in laparoscopic abdominal surgery. METHODS AND MATERIALS Forty patients were examined. Patients were randomly divided into four groups in order to receive sevoflurane-fentanyl (SF = 10), sevoflurane-N(2)O (SN = 10), desflurane-fentanyl (DF = 10), and desflurane-N(2)O (DN = 10), respectively. Tidal volume and ventilation frequency were kept unchanged during the operation. Intraabdominal pressure was remained constant at 12 mm Hg. Baseline values in venous blood samples were preoperatively taken and blood was also taken postoperatively at the 6th and the 24th hours. After collection of blood samples into citrate (3.5 mg/mL blood) containing glass tubes, erythrocyte sediments were prepared for the analyses. Then malondialdehyde levels, protein carbonyl content, and sulfhydryl (SH) groups were measured. RESULTS The levels of MDA and protein carbonyl content were significantly higher at the 6th hour rather than the 24th hour postoperatively with desflurane anesthesia. In addition, SH groups were significantly different between the 6th hour and the 24th hour measurements (P < 0.05). In our study, desflurane caused a statistically significant increase in MDA levels and protein carbonyl content and a decrease in SH groups. When the two groups were compared, in the case of MDA and CB values, a significant increase was observed in the 6th and the 24th hour, where there was a decrease in SH groups in the desflurane group (P < 0.05). These parameters did not change in the sevoflurane group (P > 0.05). CONCLUSION We concluded that desflurane was affected by desflurane with low flow anesthesia in patients undergoing laparoscopic abdominal surgery. Significant influence on oxidative stress and antioxidant mechanics was not seen with sevoflurane anesthesia. Our studies support that oxidant and antioxidant defense mechanisms were altered in the desflurane group and this alteration improved after a combination of desflurane-N(2)O.

Abstract
Laparoscopic donor nephrectomy has become the accepted method of harvesting the kidney at many institutions because of multiple advantages over open donor nephrectomy. Spiral computed tomographic (CT) angiography provides accurate information of renal vascular anatomy and has become an accepted method of preoperative evaluation of potential laparoscopic renal donors. More recently, multidetector CT (MDCT) provides more detailed datasets compared with single-detector spiral CT and has been used for preoperative evaluation of laparoscopic donor nephrectomy to provide accurate anatomic information. MDCT (especially 16- and 64-slice MDCT) angiography has advantages over single-detector helical CT due to rapid scan time that allows coverage of a large volume of interest with higher spatial and temporal resolutions. In this article, we review the current status of MDCT angiography in the evaluation of laparoscopic renal donors and potential advantages of using this technology.

Abstract
Four surgical techniques for living donor nephrectomy were analyzed retrospectively in terms of perioperative outcome and early complication rate. A total of 182 donor nephrectomies including 69 open (OLDN), 14 fully laparoscopic (LDN), 34 hand-assisted laparoscopic (HLDN) and 65 retroperitoneoscopic (RLDN) nephrectomies were analyzed. There was a significant difference in mean operating time (OPT) between the OLDN (160 min) and RLDN (150 min) as compared to the LDN (212 min) and HLDN group (192 min) (P < 0.001). Mean warm ischemia time (WIT) was significantly shorter with OLDN (114 s), RLDN (121 s) and HLDN (128 s) when compared to LDN (238 s) (P < 0.001). Major complication rate was comparable among the groups. Independent of the preferred technique, donor nephrectomy is associated with complication rates. RLDN is comparable to OLDN in terms of OPT, WIT. Learning endoscopic donor nephrectomy could be associated with a higher complication rate.

Abstract
PURPOSE To retrospectively review the authors' experience with multi-detector row helical computed tomography (CT) in assessing 100 consecutive live potential renal donors. MATERIALS AND METHODS Hospital ethical committee approval was obtained; informed patient consent was not required. One hundred potential renal donors underwent multi-detector row CT assessment. Nonenhanced, arterial phase, and nephrographic phase examinations were performed. Delayed topograms were acquired to visualize the collecting system anatomy. A vascular radiologist prospectively interpreted the multi-detector row CT images. A second vascular radiologist, blinded to the initial results, retrospectively reviewed the images. Eighty candidates subsequently underwent donor nephrectomy, including 70 laparoscopic donor nephrectomies (LDNs) and 10 open donor nephrectomies (ODNs). Surgical findings served as the reference standard for 80 kidneys. The imaging findings in all 100 candidates (200 kidneys) were reviewed, although these findings were considered observational data only because there was no reference standard for 120 kidneys. RESULTS Multi-detector row CT findings predicted uncomplicated LDN in 67 of 70 patients. Small upper-pole capsular arteries arising from the distal main renal artery in two patients were not described in the multi-detector row CT report: In one patient, the arising vessels resulted in conversion to ODN because of bleeding; in the other patient, arterial reconstruction was performed. In another patient, conversion to ODN was necessary because of ongoing bleeding from an avulsed large lumbar venous tributary to the left renal vein. Observational data revealed that multiple renal arteries--most of which were accessory renal arteries--were seen in 52 (26%) kidneys. Early branching of the main renal artery was seen in 24 (12%) kidneys, and main renal arterial abnormalities were identified in six (3%). Capsular arteries were detected in 10 (5%) kidneys. Major variations in the anatomy of the main renal veins--including multiple right renal veins, a retroaortic left renal vein, and a circumaortic left renal vein--were seen in 28 (14%) kidneys. Large (>5 mm in diameter) systemic tributaries to the left renal vein were seen in 25 (25%) kidneys. There was no significant interobserver disagreement between the vascular radiologists. CONCLUSION Multi-detector row CT findings can predict successful LDN in live potential renal donors.

Abstract
A 59-year-old woman complained of increasing pain in the left abdomen and of diarrheal symptoms after left-sided retroperitoneoscopic living donor nephrectomy. Computed tomography revealed chyloretroperitoneum. The fluid was drained percutaneously, followed by recurrent drain replacement surgery. Her diet was changed to short-chain and medium-chain fatty acids without success. After onset of dyspnea due to chylothorax, the donor underwent thoracic drainage, fully parenteral therapy, and finally somatostatin application therapy. The postoperative management of severe chylous fistula is difficult. Therefore, we recommend an early start of maximal conservative therapy. Surgical options depend on pain occurrence or mechanical problems.

Abstract
Living donors represent 30% of kidneys for renal transplantation. Laparoscopic nephrectomy is the best surgical procedure due to its clear advantages: low morbidity, less blood transfusion requirements, and shorter donor hospitalization. From March 2002 to August 2004, we performed 50 laparoscopic nephrectomies for transplantation to recipients who were prescribed tacrolimus (0.1 mg/kg bid), mycophenolate mofetil (1 gr bid), and prednisone (0.5-1 mg/kg per day PO from 48 hours before transplantation). Mean surgery time was 170 minutes (120-260); warm ischemia time, 3.1 minutes (1.5-10); and cold ischemia time, 1.27 hours (0.85-4). Mean bleeding was 270 cc (100-900), and mean donor hospitalization was 5.5 days (3-9). Four cases required conversion of the laparoscopic procedure to open surgery because of bleeding. Seventy-two hours posttransplantation, the mean plasma creatinine was 170 micromol/L. None of the patients suffered delayed graft function. Eighteen percent experienced acute rejection episodes. Donor and recipient survivals were 100% at 1 year, and graft survival, 94% (kidney losses were due to acute rejection, severe acute pancreatitis, and surgical complications).

Abstract
In this study we focused on the quality of life and satisfaction of living kidney donors comparing traditional lumbar (LDN) and mini-incision donor nephrectomy (MIDN). From May 1996 to December 2002, 174 donor nephrectomies including 127 cases of LDN and 47 cases of MIDN were performed. Donors were evaluated using the SF-36 quality-of-life survey as well as a questionnaire dealing with donors' attitude towards kidney donation, financial burdens, pain, cosmetic satisfaction and duration of sick leave. Our donors achieved comparable or even higher scores in all the SF-36 categories in comparison to the general US population. Following MIDN, quality of life tended to be superior compared to that of LDN donors; however, statistical significance was reached only in one of the eight categories. Duration of sick leave following surgery was in favor of MIDN compared to LDN donors. Statistically significant differences favoring MIDN were observed regarding postoperative hospital stay and cosmetic satisfaction. The procedure would be again undergone by 94 of LDN and 97% of MIDN donors. Open-donor nephrectomy is a safe and cost-effective procedure. Introduction of the here-described MIDN has led to comparable or even improved results compared to LDN.

Abstract
Pneumoperitoneum, as used in laparoscopic donor nephrectomy (LDN), may result in negative effects on renal function in donor and recipient. This study compares long-term serum creatinine in donor and recipient after laparoscopic and open donor nephrectomy (ODN). A retrospective analysis of 120 LDN and 100 ODN donors and their recipients was performed. Serum creatinine of donor and recipient was recorded and analyzed. The follow-up period posttransplantation was 3 years. Serum creatinine in the recipients was significantly higher in the LDN groups the first week after transplantation. Serum creatinine in the donor was significantly higher in the LDN group at 1 day, 3 months, and 1 year posttransplant. Finally, creatinine levels remained 40% higher compared to preoperative values in both donor groups. LDN results in higher short-term serum creatinine levels in donor and recipient. Long-term serum creatinine levels were comparable after LDN or ODN in donor and recipient.

Abstract
PURPOSE To determine whether living related retroperitoneoscopic donor nephrectomy (RDN) is a safe and effective procedure. PATIENTS AND METHODS From September 2001 to May 2004, RDN was performed in 50 consecutive patients at our hospital. All patients were followed longitudinally with office visits. Perioperative and postoperative data for these RDNs, including operative time, blood loss, and complications, were compared with those of open donor nephrectomies (ODNs) performed between January 1999 and December 2001. RESULTS The RDN was completed in all cases. The average warm ischemia times were 4.1 minutes (range 1.0-8.5 minutes) and 3.5 minutes (range 2.3-5.5 minutes) in the RDN and ODN groups, respectively (P = NS). The mean operative time for RDN was significantly longer than that for ODN (P < 0.001), but patients in the RDN group had significantly shorter hospital stays (P < 0.05). There was no significant difference between the groups in blood loss during operation or number of doses of analgesics administered after the operation. Perioperative and early postoperative complications occurred in 14 patients (28%) in the RDN group and consisted of subcutaneous emphysema in 9, wound infection in 3, and persistent headache in 2 patients. All kidneys removed retroperitoneoscopically functioned immediately. No recipients required post-transplant continuous hemodialysis. CONCLUSIONS The RDN is a safe and effective procedure for both donor and recipient. Although the benefits of RDN have been demonstrated, further long-term studies of graft function and patient survival are needed.

Abstract
Perioperative donor morbidity, a barrier to living organ donation, may be mitigated by the laparoscopic approach. From September 2002 to September 2004, 15 living donors, of ages ranging from 36 to 59 years, underwent laparoscopic nephrectomy. We used a hand-assisted device to increase the safety of the procedure. The average operating time was 200 minutes. The average blood loss was about 100 mL. The patients resumed oral intake and started walking within 1 day. The average postoperative hospital stay was 6 days. Although laparoscopic operating times were longer than those for traditional surgery, we showed benefits to the laparoscopic donor to be less postoperative pain, better cosmesis, shorter recovery time, and faster return to normal activities. We therefore consider laparoscopic nephrectomy a good alternative to traditional surgery for selected patients. 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.

Abstract
OBJECTIVES We retrospectively performed a comparative analysis of retroperitoneoscopic and open donor nephrectomy in terms of donor complications, as well as recipient complications and functional graft outcome. METHODS A total of 134 donor nephrectomies including 69 open (ODN) and 65 retroperitoneoscopic (RDN) nephrectomies was analyzed retrospectively. Both groups were comparable in terms of age, body mass index (BMI), operating time (OPT), warm ischemia time (WIT) and blood loss. RESULTS There were no statistically significant differences with respect to recipient outcome, mean values for age, BMI, OPT and cold ischemia time (CIT). The overall donor complication rate did not differ. Early functional graft follow-up showed significant differences in 24 h-urine output between the two groups (p<0.001), but serum creatinine was comparable after 7, 30, 180 and 365 days. The early rejection rate in the recipients was similar in the two groups. CONCLUSION Retroperitoneoscopic donor nephrectomy (RDN) provides comparable perioperative features, such as operating time, warm ischemia time (WIT) and overall complication rate to the open donor nephrectomy (ODN). Additionally, it has no negative impact on recipients' operating time, graft ischemia and early graft function.

Abstract
It is unclear whether potential living kidney donors and the general public differ in attitudes and psychological characteristics. We performed a case-control study to explore differences in these groups using a standardized questionnaire (analyzed using conditional logistic regression). Strangers (N = 42) were more willing than controls (N = 126) to incur risks: 64% strangers versus 35% controls accepting >50% medical complications (MC) risk; 90% strangers versus 61% controls accepting >8 days hospitalization; 71% strangers versus 43% controls accepting >3 months unpaid; 55% strangers versus 16% controls accepting 100% kidney failure (KF) risk; 70% strangers versus 34% controls accepting < or =10% likelihood of successful transplant (all p < 0.01). Relatives (N = 251) were also more willing than controls (N = 251) to incur risks. Strangers were most willing to incur MC, KF and transplant failure. Groups did not differ in attitudes, depression or anxiety. Potential stranger and related donors are willing to undergo greater risks with donation than the general public, but do not differ in other attitudes, depression or anxiety. This should help reassure transplant centers and the public that both forms of live donation do not necessarily involve increased ethical risks of donor coercion or irrational thought processes. Still, careful attention to communication of all risks of donation is warranted.

Abstract
This study investigates the effect of renal artery multiplicity on donor and recipient outcomes after laparoscopic donor nephrectomy. Three-hundred and sixty-one sequential procedures were performed over a 4-year period. Forty-nine involved accessory renal arteries; of these, 36 required revascularization and 13 were small polar vessels and ligated. The 312 remaining kidneys with single arteries served as controls. Study variables included operative times, blood loss, hospital stay, graft function and donor and recipient complications. Kidneys with multiple revascularized arteries had a longer mean warm ischemia time (35.3 vs. 29.2 min, p = 0.0003), and more ureteral complications (6/36 vs. 10/312, p = 0.0013) than single-artery controls. In contrast, ligation of a small superior accessory artery had no significant effect on donor operative time, blood loss, or complication rate while providing similar recipient graft function compared to single-artery controls. Renal artery number is important in selecting the appropriate kidney for laparoscopic procurement. Given the current excellent results with right-sided donor nephrectomy, kidneys with single arteries should be preferentially procured, irrespective of side.

Abstract
It is unknown whether patient-physician discussion about live kidney transplantation (LT) among African Americans (AA) is affected by preferences, knowledge and family discussions regarding LT. We recruited 182 AA dialysis patients and their families and assessed the relation of preferences, knowledge and family discussions regarding LT to the occurrence of patient-physician discussion using multivariable logistic regression. Most patients (76%) desired a transplant, and most patients (93%), spouses (91%) and children (88%) had knowledge of LT. Nearly half of the families discussed transplantation. Only 68% of patients and less than half of their spouses (41%) and children (31%) had discussed transplantation with physicians. Patient-physician discussion was more common among patients: whose spouses acknowledged their interest in transplantation (adjusted odds ratio (AOR) (95% CI):3.5 (1.61-7.8)); who discussed transplantation with spouses (AOR(95% CI):5.25 (2.22-12.41)); whose spouses agreed that they discussed transplantation with patients (AOR (95%CI):5.20 (1.76-15.37)) and whose children discussed transplantation with patients' physicians (AOR (95%CI):7.4 (1.3-40.0)). Universal patient-physician discussion of LT does not occur despite patient preferences. Rates of family-physician discussions are low, and rates of family discussions vary. Early family-physician discussion of LT, use of allied health professionals to promote family discussion of LT and the institution of culturally appropriate programs to enhance discussion of LT in AA families could improve rates of discussion and enhance patients' access to LT.

Abstract
UNLABELLED Authors from Iran compare various outcomes between laparoscopic and open donor nephrectomy in kidney transplantation; they carried out a large comparative trial, and found that laparoscopic donor nephrectomy gave better donor satisfaction and morbidity, with equivalent graft outcome. OBJECTIVE To compare the graft survival, donor and recipient outcome, donor satisfaction, and complications of laparoscopic (LDN) and open donor nephrectomy (ODN) in kidney transplantation. PATIENTS AND METHODS In a randomized controlled trial, 100 cases each of LDN and ODN were compared. We modified the standard LDN procedure to make it less expensive. RESULTS The mean (sd) operative duration was 152.2 (33.9) min for ODN and 270.8 (58.5) min for LDN, and the mean duration of kidney warm ischaemia was 1.87 min for ODN and 8.7 min for LDN. Only one LDN required conversion to ODN because of bleeding. The mean follow-up in the LDN and ODN groups was not significantly different (406.1 vs 403.8 days). The mean (sd) score for donor satisfaction was 17.3 (3.5) for ODN and 19.6 (1.0) for LDN. The rate of ureteric complications was 2% for ODN and none for LDN. As determined by serum creatinine levels at 3, 21-30, 90, 180 and 365 days after surgery, graft function was not significantly different between ODN and LDN. Long-term graft survival was 93.8% for LDN and 92.7% for ODN. CONCLUSIONS Compared to ODN, LDN was associated with greater donor satisfaction, less morbidity and equivalent graft outcome.

Abstract
We tried to establish the technique of retroperitoneoscopic live donor nephrectomy (RPLDN). Between July 2001 and March 2004, 135 renal transplant donors underwent RPLDN. Low (average: 7 mmHg) CO2 gas pressure was employed during the procedure. All procedures were performed through a three-port retroperitoneal approach without opening the peritoneal cavity. The hand-assisted technique was not used. One hundred and twenty-seven cases were of left and eight cases were of right nephrectomy. Donor nephrectomy was carried out successfully in all patients. In one donor, the procedure was changed to open donor nephrectomy because of severe adhesion around the renal vein due to previous surgery. No serious complications, such as massive bleeding or bowel injury were encountered. Return of bowel function took 0.7 days on average. Post-operative hospital stay was 4.9 days on average, and return to work was 12 days on average. Ureteral complications occurred in 2 patients and were treated with temporally retrograde ureteral stenting. Average serum creatinine levels were 1.5 mg/dL, 1.3 mg/dL and 1.3 mg/dL at 3, 7 and 14 days after transplantation, respectively. No patients required hemodialysis after transplantation due to acute tubular necrosis. RPLDN could be an option for laparoscopic live donor nephrectomy.

Abstract
Laparoscopic donor nephrectomy (LDN) is becoming the method of choice to procure kidneys from living donors. Despite the benefits to the donor, there have been concerns over the transient deterioration of renal function in the recipient of LDN compared with standard nephrectomy. We carried out a retrospective review of all living donors at our institution between January 2000 and December 2002. On the first postoperative day, the fall in renal function in laparoscopic donors is significantly greater than the fall seen in open donors. This difference could not be explained by relative hypotension, excessive blood loss, or inadequate fluid replacement in the laparoscopic group. Importantly, this difference is no longer evident by the third postoperative day. We speculate that this may be secondary to the pneumoperitoneum or the prolonged anesthesia on glomerular filtration rate. Furthermore, this finding could explain the slower recovery of graft function in recipients of laparoscopically procured kidney transplants.

Abstract
INTRODUCTION We retrospectively compared perioperative donor outcomes and early postoperative pain control after retroperitoneoscopic (RLDN) and standard open (OLDN) living donor nephrectomy. METHODS One hundred donors included fifty after RLDN (37 women/13 men) and 50 after OLDN (35 women/15 men) were retrospectively analyzed for basic analgesics, for opioid consumption, and for visual analog scale (VAS) to verify the experienced pain. The donors were questioned in the morning and evening of the first through fifth postoperative days. RESULTS The mean age of both groups was equal. The mean operating time was 149.7 +/- 48.2 minutes (60 to 270) for RLDN and 164.1 +/- 30.3 minutes (60 to 240) for OLDN (P = NS). The mean warm ischemia time was 120 +/- 36 seconds (50 to 240) and 114 +/- 31 seconds (60 to 190) for the RLDN and OLDN groups, respectively (P = NS). The mean evening VAS for RLDN versus OLDN on postoperative days 1 to 5 was: 2.1 versus 2.2 (P = NS), 0.9 versus 1.8 (P = .009), 0.5 versus 1.3 (P = .016), 0.1 versus 0.7 (P = .013), and 0.1 versus 0.7 (P = .013), respectively. In both groups there was a tendency toward a higher VAS score in the morning than in the evening. RLDN donors showed significantly earlier period free of pain (VAS = 0) than those after OLDN. There was a significant difference of being free from any opiate between both groups after surgery. CONCLUSIONS After RLDN donors experienced less postoperative pain than after OLDN over the early postoperative days. Therefore, postoperative regional anesthesia is not necessary for donors operated by a retroperitoneoscopic approach.

Abstract
BACKGROUND Laparoscopic living-donor nephrectomy has gained acceptance within the transplant community. The technique requires advanced laparoscopic techniques, and great care must be taken to ensure safety of the operation for the donor and transplantability of the donor kidney. Minimizing the risk of bleeding and trauma to the kidney are important features of a successful living-donor nephrectomy. Improved laparoscopic instrumentation has afforded greater safety and efficacy through technical advances. METHODS The LigaSure device was used in 124 consecutive living-donor nephrectomies beginning in 1999. A transplant database was reviewed for operative statistics including intraoperative blood loss and operating time. RESULTS The LigaSure device was used to dissect and seal all venous and arterial branches. Estimated blood loss was 90 +/- 53 mL. A suction device was required in only 40 (32%) of the cases. No patient experienced postoperative bleeding. There were two donor complications: one incisional hernia and one ileus. All kidneys functioned immediately upon reperfusion. CONCLUSIONS The LigaSure device is an extremely effective tool for obtaining hemostasis by sealing both venous and arterial branches of the major renal vessels. This is also effective in sealing lymphatic tissues and thereby facilitating dissection. Avoiding the use of metallic clips simplified final division of the renal artery and vein. As with any laparoscopic instrument, the anatomic geometry of the operative field may limit use based upon port placement.

Abstract
PURPOSE Laparoscopic donor nephrectomy (LDN) is an increasingly accepted modality for procuring donor kidneys for transplantation. We analyzed and compared the short and long-term outcomes of living transplant allografts from kidneys procured by laparoscopic or open donor (ODN) technique and managed with a single immunosuppression regimen in each group. MATERIALS AND METHODS Records of recipients who underwent living (laparoscopic or open) donor nephrectomy were reviewed from August 1999 to July 2001 for LDN and from January 1994 to December 1999 for ODN. Patients included were on a single immunosuppression regimen particular to each group. Sirolimus, mycophenolate mofetil and prednisone were given to the LDN group, and calcineurin inhibitor (FK-506 or cyclosporine), mycophenolate mofetil and prednisone were given to the ODN group. Excluded from study were patients with prior kidney transplant or patients not receiving immunosuppression as previously described. Also excluded from study were patients lost to followup before 1 year. Data were retrieved retrospectively from case notes or from the transplant database and analyzed using SAS software (SAS Institute, Cary, North Carolina). RESULTS A total of 71 patients from the LDN group and 60 patients from the ODN group qualified for the study. Demographic data are comparable in both groups except for the significantly longer followup in the ODN group. Serum creatinine was 2.2 and 1.8 mg/dl at postoperative day 4, 1.3 and 1.3 mg/dl at day 10, and 1.3 and 1.4 mg/dl at 1 month in the LDN and ODN groups, respectively. Time to achieve nadir serum creatinine was 8.7 versus 6.6 days for LDN and ODN groups, respectively (p = not significant). Delayed graft function was noted in 5 of 71 (7%) in the LDN group and 3 of 60 (5%) in the ODN group (p = 0.5). In the LDN group 13 (18%) patients had a serum creatinine of greater than 1.5 mg/dl at postoperative day 30 compared to 6 (10%) in the ODN group (p = 0.06). Mean serum creatinine at 1 year was lower for LDN recipients (p = not significant). But at last followup this difference became statistically significant in favor of LDN. Mean followup was 939 versus 2,046 days for LDN versus ODN, respectively (p <0.0001). Recipient mean hospital stay was 5.2 versus 6.7 days for LDN versus ODN, respectively (p = 0.08). There were 8 of 78 (10.2%) episodes of acute rejection in the LDN group compared to 22% in the ODN group (p = 0.08). The complication rate (ureteral vascular, lymphocele, acute rejection and wound) was 11% in LDN compared to 15% in the ODN group. Long-term graft function, graft survival and patient survival in the LDN group were comparable to the ODN group. CONCLUSIONS Early graft recovery is slower in LDN allografts, although not statistically significant, but long-term function in the LDN group is significantly better compared to the ODN group. Laparoscopic donor kidneys take longer to achieve nadir serum creatinine, but this does not influence long-term outcome and results.

Abstract
BACKGROUND There are no data concerning the national experience with laparoscopic live donor nephrectomy (LLDN) in Italy. A survey was therefore conducted in May 2003 to establish current practice patterns and to describe the outcome of this procedure. METHODS A self-administered questionnaire was mailed to the 37 Italian kidney transplant centers. Items covered each center's attitude toward LLDN, number of cases performed, and the outcome of donors and recipients. RESULTS The return rate was 100%. The surveyed centers performed 4818 kidney transplants between January 2000 and May 2003, including 401 (8.3%) from living donors of whom 113 (28.2%) used grafts retrieved by laparoscopy. Despite an absolute increase in the number of living donors, the occurrence of a similar trend in cadaveric donation did not significantly change the overall living donor rate. Sixty-eight percent of LLDNs were done at only two centers. There was no mortality or graft loss and only a minor morbidity related to LLDN. Italian transplant surgeons showed a positive attitude toward LLDN; only a few of those not performing it had no plans to begin an LLDN program. CONCLUSIONS Three years after the first national case, LLDN had not yet change the living donor rate, although an increasing number of donor nephrectomies were now performed by laparoscopy. Overall the results with the new technique are encouraging, although the pattern of diffusion of LLDN between different areas is heterogeneous and will demand continuous efforts on training programs in laparoscopic techniques for transplant surgeons.

Abstract
Laparoscopic donor nephrectomy (LDN) and minimal-incision donor nephrectomy (MILD) are less invasive procedures than the traditional open donor nephrectomy approach (ODN). This study compares donor and recipient outcome following those three different procedures. Sixty consecutive donor nephrectomies were studied (n = 20 in each group). Intra-operative variables, analgesic requirements, donor recovery, donor/recipient complications and allograft function were recorded prospectively. Operating and first warm ischaemia times were longer for LDN than for ODN and MILD (232+/-35 vs 121+/-24 vs 147+/-27 min, P < 0.001; 4+/-1 vs 2+/-2 vs 2+/-1 min, P < 0.01). Postoperative morphine requirements were significantly higher after ODN than after MILD and LDN (182+/-113 vs 86+/-48 vs 71+/-45 mg; P < 0.0001). There was no episode of delayed graft function in this study. Donors returned to work quicker after LDN than after ODN and MILD (6+/-2 vs 11+/-5 vs 10+/-7; P = 0.055). Donor and recipient complication rates and recipient allograft function were comparable. We concluded that MILD and LDN reduce postoperative pain and allow a faster recovery without compromising recipient outcome.

Abstract
BACKGROUND Patients undergoing laparoscopic live donor nephrectomy (LLDN) commonly receive large amounts of fluid intraoperatively to counter the negative effects of pneumoperitoneum on renal function. Our aim is to demonstrate that a low-volume fluid management strategy does not adversely affect donor or recipient outcomes. METHODS Fifty-two patients underwent LLDN between December 2000 and January 2004. Data were collected in prospective databases, and augmented with retrospective medical record review. Donors were divided into two groups: the fluid-load group (n = 24) received > 10 ml/kg/h of intravenous crystalloids intraoperatively, while the fluid-restriction group (n = 28) received < 10 m/kg/h. RESULTS Donors in the fluid-restriction group had a lower intraoperative urine output. There were no differences in postoperative creatinine levels (117.5 micromol/L vs 121.5 micromol/L, p = 0.8) or complications (4.2% vs 7.1%, p = 0.9). In the recipients, there were no differences in postoperative creatinine levels up to 12 months, incidence of delayed graft function (18% vs 10%, p = 0.7) or acute rejection (9% vs 5%, p = 1.0) between groups. CONCLUSION Lower volume fluid management strategies in LLDN do not appear to worsen recipient outcomes nor are they detrimental to the donors.

Abstract
Laparoscopic surgery has become a preferred treatment option for the management of upper urinary tract pathology. Large series of complex urologic operations have been published, with favorable outcomes. Although the early experience with urologic laparoscopy consisted almost exclusively of transperitoneal procedures, some surgeons prefer the retroperitoneal approach. The debate of retroperitoneal versus transperitoneal laparoscopy for upper tract pathology is complex because comparative and randomized studies are lacking. In contrast to the retroperitoneal approach, transperitoneal laparoscopic procedures allow for a larger working space, adequate maneuverability, and the presence of familiar anatomic landmarks. This article highlights our experiences and approaches to major laparoscopic upper urinary tract surgery for benign and malignant conditions. A summary of the published literature as it pertains to the transperitoneal approach also is presented.

Abstract
BACKGROUND Laparoscopic donor nephrectomy (LDN) is being adopted rapidly by transplant centres around the world as it offers less postoperative pain, quicker convalescence, and better cosmetic result when compared with the open approach. There may, however, be a steep learning curve with this technique. METHOD A retrospective review was performed to evaluate the donor morbidity and graft outcome of 21 consecutive LDN performed at one centre between May 2002 and August 2003. RESULTS Eighteen LDN were performed on the left and three on the right side. All left and one right LDN were done transperitoneally while the remaining two right side kidneys were removed by a retroperitoneal approach. The mean (+/-SD) operating time and warm ischemic time were, respectively, 236 minutes (+/- 46) and 4 minutes (+/- 1). The mean time for resuming oral intake was 23 hours (SD +/- 22.7). The median length of hospital stay was 5 days (range 3 to 18). One patient was reoperated for bleeding and required four units of packed cell transfusion. One recipient displayed delayed graft function requiring dialysis for 14 days. There were no graft losses. The mean creatinine of the recipients at the time of discharge was 1.15 mg/dL (+/- 0.21). CONCLUSIONS There is undoubtedly a learning curve with LDN. Nevertheless, with prior skills in similar procedures such as laparoscopic radical nephrectomies, it is feasible to diminish the learning curve and morbidity of LDN to yield results consistent with those in the published literature.

Abstract
BACKGROUND Although the advent of hand-assisted laparoscopic donor nephrectomy (HLDN) has had a positive impact on the donor pool, there is still some concern about its safety. The aim of this study was to assess the impact of a change in surgical access to live-donor nephrectomy on donor-related complication rates, the renal function of the donor, and the graft function of the recipient. METHODS At our hospital, HLDN was introduced in 1998. Thereafter, we compared 49 consecutive donors undergoing open donor nephrectomy (ODN) between 1987 and 2002 with 57 consecutive donors undergoing HLDN between 1998 and 2002. Donor renal and recipient graft functions were assessed by measuring creatinine levels and urine output, with the addition of warm and cold ischemia time and dialysis requirements in the latter group. Data are presented as means (+/-SD) and analyzed with the Student t-test or Fisher's exact test. RESULTS The ODN and HLDN donors were comparable for age, gender, body mass index, renovascular anatomy, and preoperative creatinine. Estimated blood loss (370 +/- 280 vs 168 +/- 160 ml, p < 0.0001), time to resumption of oral intake (1.7 +/- 0.5 vs 1.3 +/- 0.7 days, p = 0.01), duration of intravenous narcotic requirements (23 +/- 0.7 vs 1.7 +/- 1.0 days, p < 0.0001), and hospital stay (4.2 +/- 1.4 vs 2.9 +/- 1.3 days, p < 0.0001) were significantly decreased after HLDN. There were no significant differences between ODN and HLDN in operating time (204 +/- 46 vs 202 +/- 49 min), donor-related complication rates (12.2% vs 14%), or donor renal and recipient graft functions. CONCLUSION The introduction of HLDN to an established renal transplant program led to an improved short-term outcome without any increase in donor-related complication rates or delay in recipient graft function.

Abstract
OBJECTIVE To review a single-institution 6-year experience with laparoscopic live donor nephrectomy detailing the technical modifications, clinical results, as well as the trends in donor and recipient morbidity. SUMMARY BACKGROUND DATA Since 1995, laparoscopic donor nephrectomy has had a significant impact on the field of renal transplantation, resulting in decreased donor morbidity, without jeopardizing procurement of a high-quality renal allograft. This technique has become the preferred method of allograft procurement for many transplantation centers worldwide but still remains technically challenging with a steep learning curve. METHODS Records from 381 consecutive laparoscopic donor nephrectomies were reviewed with evaluation of both donor and recipient outcomes. Trends in donor and recipient complications were assessed over time by comparing the outcomes between four equally divided groups. RESULTS All 381 kidneys were procured and transplanted successfully with only 8 (2.1%) open conversions. Mean operative time was 252.9 +/- 55.7 minutes, estimated blood loss 344.2 +/- 690.3 mL, warm ischemia time 4.9 +/- 3.4 minutes, and donor length of stay was 3.3 +/- 4.5 days. There was a significant decline in total donor complications, allograft loss, and rate of vascular thrombosis with experience. The rate of ureteral complications declined significantly when comparing our early (Group A) versus later (Groups B-D) experience. CONCLUSION Laparoscopic donor nephrectomy has remained a safe, less invasive, and effective technique for renal allograft procurement. Over our 6-year experience and with specific refinements in surgical technique, we have observed a decline in both donor and recipient morbidity following laparoscopic live donor nephrectomy.

Abstract
MR imaging provides a comprehensive method for noninvasive evaluation of renal donor anatomy. Although multidetector helical CT can provide similar information, MR imaging has the advantage of avoiding exposure to ionizing radiation and potentially nephrotoxic contrast material. These are important considerations in screening a generally healthy donor population. MR imaging also can provide complete evaluation of the kidney after transplantation, where avoidance of potentially nephrotoxic agents and preservation of maximal renal function are critical.

Abstract
UNLABELLED We evaluated the histopathology of donor kidneys procured by laparoscopic donor nephrectomy (LDN), by examining allograft biopsy specimens obtained immediately after donor nephrectomy (0-h biopsies). MATERIALS AND METHODS LDN was performed on 65 donors between December 1999 and November 2002, in our institution. Their mean age was 56 years, and there were 19 males and 46 females. Hand-assisted LDN (HALDN) was used in 10 cases and retroperitoneal LDN (RPLDN) in 55 cases. Allograft biopsy of all 65 kidneys was performed immediately after LDN (0-h biopsy), and the biopsy specimens were used in this study. All specimens were routinely examined by light and immunofluorescence microscopy. The 43 donors who underwent traditional open donor nephrectomy (ODN) between January 2001 and June 2001 served as controls. RESULTS There was no significant difference in the rate of glomerular sclerosis and moderate interstitial fibrosis with tubular atrophy, the severity of arteriosclerosis, and the severity of arteriolar hyalinosis among the specimens from kidneys removed by the three different methods: HALDN, RPLDN, and ODN. Prominent and characteristic histopathological changes which are not usually seen in 0-h biopsy specimens of kidneys obtained by traditional ODN were 'subcapsular cortical damage (SCCD) with capsular lesions (CL)'. The SCCD with CL changes included a subcapsular degeneration and necrosis of tubular cells and a congestion of glomerular and peritubular capillaries (SCCD) associated with haemorrhage and fibrin deposits in the renal capsule (CL). In this study, such characteristic 'SCCD with CL' findings were observed in 35 specimens (54%). The damage was much milder in donor kidneys procured by RPLDN than by HALDN. CONCLUSION SCCD with CL occurred in donor kidneys procured by LDN, which may be due to a compression of the renal parenchyma and veins. RPLDN may be better method for donor nephrectomy.

Abstract
BACKGROUND Living donor nephrectomy (LDN) is a unique surgical challenge where surgery is performed on a healthy individual. A new hand-assisted retroperitoneoscopic nephrectomy (HARS) technique was compared to transperitoneal laparoscopic nephrectomy (LAP) and open nephrectomy (OPEN). The aim was to examine the perioperative and postoperative morbidity, and the effects of the different surgical techniques with regard to renal function. METHODS Donors (n=36) were divided into three groups (HARS, LAP and OPEN) according to surgical technique. During the operations, renal function, hormone output, warm ischemia time (WIT) and operating time were recorded. Renal function, complications, convalescence and allograft outcome were followed postoperatively for one year. RESULTS OPEN and HARS groups showed similar operation times: 150 (95-218) minutes and 145 (124-225) minutes, respectively. LAP procedures took longer: 218 (163-280) minutes. OPEN had the shortest WIT at 91 (55-315) seconds; LAP had the longest WIT at 207 (100-319) seconds, with HARS at 180 (85-240) seconds. In all groups, glomerular filtration rate and urine production were decreased during surgery. Endoscopic techniques had a higher catecholamine release, and OPEN donors showed higher serum aldosterone. Endoscopic techniques showed shorter convalescence and less postoperative pain compared to OPEN. HARS had a smaller rise in creatinine than LAP, and HARS recipients a better creatinine clearance than the other groups in the early posttransplantation period. CONCLUSIONS Evaluation of HARS shows that the operation is quick, the donors experience little pain, and recovery time is short. The renal function for donors and recipients is somewhat favorable to open surgery and transperitoneal laparoscopic approaches.

Abstract
A purely retroperitoneoscopic approach in living kidney donation is used by only a few centers worldwide. Data from 28 consecutive purely retroperitoneoscopic living donor nephrectomies (RLDN) were compared to the most recent 30 open living donor nephrectomies (OLDN). Right-sided donation was performed in 12 cases (43%) of the RLDN and 11 cases (37%) of the OLDN. Comparison of the results between the two groups showed a shorter operation time and hospital stay for the RLDN group (P < 0.001). Warm ischemia time was significantly shorter in the OLDN group (P < 0.02). The rate of complications did not differ significantly between the groups. No significant difference in terms of renal graft function was detected within 30 days after surgery. As a result of the direct access, RLDN is superior in terms of operation time, even to the open access on our series, while maintaining the advantage of minimal invasiveness.

Abstract
BACKGROUND Minimally invasive, living-donor nephrectomy (LDN) is an attractive procedure for the donor in kidney transplantation (KTx). Its advantages include better cosmesis, shorter hospital stay, and rapid recovery. The most commonly performed, minimally invasive nephrectomy is done laparoscopically. However, the technical challenges, a steep learning curve for the surgeon, the risk of impaired early graft function, and the high cost of the procedure, have prevented minimally invasive LDN from gaining wide acceptance. To overcome these problems, we have developed a new surgical procedure named video-assisted minilaparotomy (VAM) for LDN. VAM-LDN is performed entirely with a small retrieval incision. Moreover, it does not require the induction of pneumoperitoneum, thereby avoiding potential vascular and renal complications. METHODS We evaluated the outcome of transplant recipients receiving kidneys with the VAM-LDN procedure by retrospectively comparing the surgical outcomes of patients who underwent KTx with the conventional open nephrectomy (group I, n=82) and VAM-LDN (group II, n=70) procedures from March 1, 1997, to June 30, 2002, at our institution. We compared postoperative complications, patient and graft survival, and graft functions between these two groups during a 12-month follow-up period. RESULTS There were no differences in demographic data, ABO compatibility, degree of human leukocyte antigen matching, or method of immunosuppression between the two groups (P >0.05). No significant difference was observed in complications such as delayed graft function, acute rejection, ureter complication, graft failure, or patient's mortality. There was no difference in graft function between the two groups, as determined by serum creatinine level measured during the 12-month follow-up. CONCLUSION The short-term recipient outcome was favorable in patients who underwent KTx with the VAM-LDN procedure.

Abstract
Since its introduction in 1995, laparoscopic nephrectomy has become the preferred technique at many medical centers for the harvesting of kidneys from living donors for transplantation. Because the field of view at laparoscopic surgery is limited, preoperative radiologic evaluation of the donor's anatomy---the renal veins and arteries, collecting system, and parenchyma--is critical. Spiral computed tomographic (CT) angiography is a fast, safe, minimally invasive, and generally accepted method for preoperative evaluation of the renal vessels. Multi-detector row CT scanners offer shorter image acquisition time, narrower collimation, better spatial resolution, and less tube heating than do single-detector row CT scanners. Multi-row scanners also provide more complete anatomic coverage, increased contrast enhancement of the arteries, and greater longitudinal spatial resolution--all of which are important both for accurate imaging of the renal vasculature and for three-dimensional postprocessing of image data. Dual-phase multi-detector row CT angiography combined with three-dimensional postprocessing enables minimally invasive and highly accurate depiction of the preoperative donor anatomy. To make the most effective use of this method, radiologists must be familiar with its technical aspects, advantages, and potential pitfalls. They also must be able to identify variations in vasculature and in renal and extrarenal anatomy that are important for laparoscopic donor nephrectomy.

Abstract
OBJECTIVE To describe modifications to laparoscopic live-donor nephrectomy (LLDN) to make it more cost-effective for developing countries; LLDN was developed as a better alternative to conventional donor nephrectomy, with advantages of an earlier return to normal activities and smaller scars, but is not popular in developing countries because of high cost of disposable items. PATIENTS AND METHODS From January 2000 to January 2002, 148 LLDNs were performed, of which two used a hand-assisted technique, 17 the standard technique, 79 a modified laparoscopically assisted cost-saving approach and 50 by the modified technique. In the latter approach the kidney was delivered through a 6-8 cm anterior subcostal flank incision. In last 50 patients we further modified the technique, clipping the hilum using endoclips and delivering the kidney by holding the lateral pararenal fat through a 5 cm iliac fossa incision. RESULTS The mean age, operative duration, warm ischaemia time, blood loss, analgesic requirements, pain score and hospital stay were comparable among the various techniques used. Re-exploration was required in four patients (bleeding in two, trocar-induced bowel injury in two). Immediate complications after surgery occurred in 20% of patients. Using endoclips, the cost was considerably reduced, from $400 to $290. The iliac fossa incision was aesthetically pleasing and more acceptable to patients. CONCLUSION These modifications are relevant in the context of a developing nation, as they provide all the benefits of LLDN at reduced cost and with better cosmetic results.

Abstract
OBJECTIVES To describe our experience with laparoscopic donor nephrectomy (LDN) and open donor nephrectomy (ODN) regarding ureteral complications. LDN has proved to be safe and to offer significant benefits to the donor compared with ODN. Of major importance is the effect of the surgical technique on the graft. Studies have shown an increased incidence of ureteral complications in recipients of laparoscopically procured kidneys. Operative reconstruction results in additional morbidity for the recipient. METHODS Living donors and their recipients, who underwent surgery from January 1994 to April 2002, were included in this retrospective study. A total of 122 LDN and 77 ODN recipients were included. RESULTS Of the 122 LDN and 77 ODN recipients, 15 (12%) and 10 (13%), respectively, required percutaneous nephrostomy drainage. In total, 5 LDN (4.1%) and 5 ODN (6.5%) recipients required reconstruction of the ureter because of obstruction of the ureter or urine leakage (P value not statistically significant, excluding reconstruction required for technical errors). The operating time, warm ischemia time, and serum creatinine were comparable between recipients with or without ureter complications requiring reconstruction. CONCLUSIONS In our experience, LDN was not associated with an increased incidence of ureteral complications in the recipient compared with ODN.

Abstract
PURPOSE We present the incidence of complications and conversions during laparoscopic nephrectomy performed for various indications and discuss methods to help prevent future complications. MATERIALS AND METHODS From June 1999 to February 2003 at our institution 285 laparoscopic nephrectomy cases were performed, consisting of 113 radical nephrectomies, 101 donor nephrectomies, 27 simple nephrectomies, 23 partial nephrectomies and 21 nephroureterectomies. We reviewed the data base of patients who underwent laparoscopic nephrectomy to examine complications and analyze factors related to conversion to an open surgical procedure. RESULTS Major complications occurred in 16 patients (5.6%). Major complications were surgical in 12 patients and medical in 4. Of the major surgical complications 3, 6, 1, 1 and 1 occurred during laparoscopic radical nephrectomy, donor nephrectomy, nephroureterectomy, simple nephrectomy and partial nephrectomy, respectively. The predominant major surgical complication was bleeding requiring conversion to an open surgical procedure. The overall conversion rate was 4% (12 patients), consisting of 6 emergency and 6 elective conversions. The remaining 27 patients experienced minor surgical or postoperative medical problems, such as urinary retention or wound infection. The mortality rate in our series was 0%. CONCLUSIONS Laparoscopic renal surgery is becoming a routine procedure in the armamentarium of many urologists. Complications that are unique to laparoscopy exist but they should decrease with time with repetition and experience. We have learned many different precautions and procedures that should help decrease the risk of future complications associated with laparoscopic renal surgery.

Abstract
Abstract
Background
Hand-assisted laparoscopic donor nephrectomy (HLDN) may have advantages over laparoscopic donor nephrectomy, such as shorter learning curve, operation and warm ischaemia times. The aim of this study was to evaluate the feasibility and safety of HLDN.
Methods
Between January 2000 and October 2002, 50 consecutive HLDN procedures were performed through a low transverse abdominal incision, 23 right sided and 27 left sided.
Results
The median age of the donors was 44 years. No HLDN required conversion to an open procedure. The median operating time for HLDN was 153 min. The median warm ischaemia time was 3 (range 1·0–4·5) min and the median blood loss was 50 (range 20–500) ml in both left- and right-sided procedures. Eight patients suffered ten minor complications during their admission. The duration of hospital stay was 5 days for donors. Three recipients developed graft failure owing to acute rejection, renal vein thrombosis and ischaemic necrosis.
Conclusion
Both left- and right-sided HLDN procedures were feasible and safe through a low transverse abdominal incision.

Abstract
BACKGROUND Laparoscopic live donor nephrectomy (LLDN) is increasingly used by transplantation centers worldwide. As in open live donor nephrectomy, the left kidney is preferred for LLDN; however, not all potential donors have anatomy conducive to left nephrectomy. The purpose of our study, therefore, was to report on a large, single-institution experience with right LLDN performed using a hand-assisted, transperitoneal approach. METHODS We performed a retrospective review of 40 consecutive patients who underwent transperitoneal right hand-assisted LLDN at our institution. Information on donor age, relation to recipient, and indication for right-sided donation was collected. Surgical demographics included operative time, warm ischemia time, and estimated blood loss. Recipients were followed for graft loss and for long-term renal allograft function. RESULTS The indications for right-sided donor nephrectomy were a difference in split renal function of greater than 10%, multiple left renal vessels, and right renal cysts. The mean surgical time in our series was 115.8 min, with a mean estimated blood loss of 85.7 mL and a warm ischemia time of 116.0 seconds. Surgical and postoperative complications were limited. Mean serum creatinine levels in the recipients were 1.6 mg/dL on day 7, 1.4 mg/dL on day 30, and 1.4 mg/dL at 1 year after transplantation. CONCLUSIONS Right LLDN using a hand-assisted, transperitoneal technique was performed with minimal morbidity and favorable graft function. We believe that offering hand-assisted LLDN to patients with an indication for right-sided donation can safely and effectively increase the pool of donor organs available to patients with end-stage renal disease.

Abstract
Laparoscopic donor nephrectomy is a new technique. For anatomical and technical reasons, many transplant centers restrict laparoscopic donor nephrectomy to kidneys with a single artery. However, we believe that with increased experience, laparoscopic donor nephrectomy in cases of multiple renal arteries does not affect donor or recipient outcomes. Among 115 living related renal transplantations performed between January 1996 and December 2002, 31 nephrectomies were performed via laparoscopy including eight with multiple arteries and 84 via an open approach, including nine with multiple arteries. The 17 patients with multiple arteries at the two procedures were compared in terms of donor and recipient outcomes. All the patients received the same immunosuppressive regimen. The demographic data were similar in the two groups. Mean durations of the donor operations (223 vs 247 minutes), side of nephrectomy (left/right, 5/4 vs 7/1), mean warm ischemia times (230 vs 432 seconds), mean serum creatinine levels at the end of 1 year follow-up, were statistically similar for the open versus the laparoscopy groups. Urological (11.1% vs 25%) and vascular complication rates (22.2% vs 25%), acute rejection rates (11.1% vs 12.5%) were also statistically similar for open versus laparoscopy groups, respectively. One-year patient and graft survival rates were 87.5% for both groups. Laparoscopic donor nephrectomy was as safe a procedure as open surgery even in the presence of multiple renal arteries in the hands of experienced transplants surgeons.

Abstract
BACKGROUND AND PURPOSE Laparoscopic donor nephrectomy causes increased renal oxidative stress. There are no data about the effects of the retroperitoneoscopic route. The aim of our study was to evaluate the oxidative stress occurring in renal tissues during retroperitoneoscopic donor nephrectomy in a rabbit model. MATERIALS AND METHODS Eighteen adult rabbits were randomized to three groups, each consisting of six rabbits. Group I (control) underwent 50-mL balloon dissection of the left retroperitoneal space without CO(2) insufflation. Group II (pneumoretroperitoneum) received a 3-hour CO(2) insufflation at a pressure of 10 mm Hg in the retroperitoneal space after balloon dissection. Group III (pneumoretroperitoneum with warm ischemia), in addition to the procedure applied in Group II, underwent left renal artery clamping for 3 minutes and reperfusion for the next 5 minutes. Bilateral nephrectomy was performed in all animals for analysis of oxidative stress markers. Concentrations of malonyldialdehyde (MDA), protein carbonyl, and reduced glutathione (GSH) were measured in renal tissue samples. RESULTS The MDA and protein carbonyl content were increased both in the donor (P = 0.004 and P = 0.004, respectively) and in the remaining kidneys (P = 0.009 and P = 0.028, respectively) in Group II compared with Group I. There were no statistically significant increases in oxidative stress markers between Group II and Group III in donor kidneys. However, there were statistically significant decreases in MDA in the remaining kidneys in Group III compared with Group II (P = 0.009). CONCLUSION Pneumoretroperitoneum causes increased oxidative stress in both donor and remaining kidneys. Short-term warm ischemia and reperfusion do not exert an additive effect on pneumoretroperitoneum-associated oxidative stress in donor kidneys.

Abstract
Minimally invasive surgery has gained wide acceptance as a method of reducing postoperative pain and curtailing the convalescence period. We have devised a modified surgical technique of video-assisted surgery through minilaparotomy (VAMS). This technique is a hybrid of conventional open and laparoscopic surgery that combines the benefits of both techniques by reducing postoperative pain and scarring, as in laparoscopy, but at the same time maintaining the safety of conventional open surgery. Video-assisted procedures have become standard as a result of our experience with 245 consecutive patients operated on between January 1993 and January 2001. The VAMS is a minimally invasive technique that is safe, feasible, standardized, and reproducible with a short learning curve. This technique can be an alternative to open and laparoscopic surgery in daily urologic practice.
