Abstract
OBJECTIVES Regional lymphadenectomy for urothelial carcinoma of the upper urinary tract is sometimes avoided in older patients to reduce surgical burden. We aimed to evaluate the therapeutic impact of lymphadenectomy in older patients undergoing curative therapy for upper urinary tract urothelial carcinoma. METHODS The patients with urothelial carcinoma of the upper urinary tract older than 75 years at the time of surgery and without lymph node or distant metastasis who underwent curative therapy at two tertiary hospitals between 1994 and 2019 were retrospectively analyzed. Complete-lymphadenectomy was performed as per our protocol. Cancer-specific survival, overall survival and metastasis-free survival after surgery were evaluated between complete-lymphadenectomy and no/incomplete-lymphadenectomy groups before and after 1:1 propensity score matching. RESULTS The original cohort included 150 patients (median age, 80.71 years), and complete-lymphadenectomy was performed in 42 (28.00%) patients. Patients in complete-lymphadenectomy group were younger and less likely to be aged >80 years (both, P < 0.0001). After matching, 30 patients were allocated to each group and the ages were comparable (78.58 vs. 77.48 years, P = 0.1738). High-grade perioperative complication rates did not differ between groups both before and after matching. Cancer-specific survival, overall survival and metastasis-free survival were significantly longer in the complete-lymphadenectomy group both before and after matching (all, P < 0.05). CONCLUSIONS This study suggests that complete-lymphadenectomy may provide therapeutic benefits for older patients. The decision to perform complete-lymphadenectomy must be based on the patient's physical condition, rather than his/her chronological age.

Abstract
BACKGROUND The aim of this study is to summarize and quantify the current evidence on the therapeutic efficacy of laparoscopic radical nephrectomy (LRN) compared with open radical nephrectomy (ORN) in patients with renal cell carcinoma (RCC) in a meta-analysis. METHODS Data were collected by searching Pubmed, Embase, Web of Science, and ScienceDirect for reports published up to September 26, 2016. Studies that reported data on comparisons of therapeutic efficacy of LRN and ORN were included. The fixed-effects model was used in this meta-analysis if there was no evidence of heterogeneity; otherwise, the random-effects model was used. RESULTS Thirty-seven articles were included in the meta-analysis. The meta-analysis showed that the overall mortality was significantly lower in the LRN group than that in the ORN group (odds ratio [OR] =0.77, 95% confidence interval [CI]: 0.62-0.95). However, there was no statistically significant difference in cancer-specific mortality (OR=0.77, 95% CI: 0.55-1.07), local tumor recurrence (OR=0.86, 95% CI: 0.65-1.14), and intraoperative complications (OR=1.27, 95% CI: 0.83-1.94). The risk of postoperative complications was significantly lower in the LRN group (OR=0.71, 95% CI: 0.65-0.78). In addition, LRN has been shown to offer superior perioperative results to ORN, including shorter hospital stay days, time to start oral intake, and convalescence time, and less estimated blood loss, blood transfusion rate, and anesthetic consumption. CONCLUSION LRN was associated with better surgical outcomes as assessed by overall mortality and postoperative complications compared with ORN. LRN has also been shown to offer superior perioperative results to ORN.

A nonrandomized prospective comparison of robotic-assisted partial nephrectomy in the elderly to a younger cohort: an analysis of 339 patients with intermediate-term follow-up. Urology 2015; 84:838-43. [PMID: 25260445 DOI: 10.1016/j.urology.2014.07.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2014] [Revised: 06/22/2014] [Accepted: 07/01/2014] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To assess the role of robotic-assisted partial nephrectomy (RAPN) in elderly patients focusing on perioperative, functional, and oncologic outcomes in comparison with a younger cohort. MATERIALS AND METHODS From a prospectively maintained institutional review board-approved database, 339 patients were divided into 2 groups defined by age ≥ 70 (n = 71) or <70 years (n = 268) at the time of RAPN. They were compared for perioperative outcomes and complications, including risk of chronic kidney disease (CKD) stage progression. The standard t test and chi square test were used for continuous and categorical variables, respectively. Logistic regression identified risk factors for progression of renal dysfunction. Kaplan-Meier estimates modeled tumor recurrence at 368 and 462 days in the elderly and young, respectively. RESULTS Elderly patients were more likely to have hypertension (86% vs 60%; P < .001) or coronary artery disease (27% vs 9%; P < .001), and rates of chronic obstructive pulmonary disorder and diabetes were also higher. Preoperative estimated glomerular filtration rate was significantly lower in the elderly (70 vs 82 mL/min/1.73 m2; P < .001). Twenty-four percent of elderly patients progressed in CKD stage as compared to 14% in the younger cohort (P = .08). Elderly age was not a statistically significant risk factor for CKD progression (relative risk, 2.34; 95% confidence interval, 0.81-6.05; P = .11). Surgical and medical complication rates were similar between the cohorts (P = .75 and .80, respectively) as were Kaplan-Meier estimates of risk of tumor recurrence (P = .47). Limitations include nonrandomized, single-center study, and intermediate-term follow-up for oncologic outcomes. CONCLUSION Elderly patients undergoing RAPN had no increased risk of perioperative complications. CKD progression and risk of oncologic recurrence were similar to younger patients at intermediate-term follow-up.

Abstract
Introduction: There is a paucity of a standardized post-operative complications grading system in urology especially in the elderly population. Studies show satisfactory survival and oncological outcomes albeit with a slight increase in post-operative morbidity compared to younger patients. The Clavien-Dindo classification for post-operative complications is established as a valid system worldwide and applicable in many fields of surgery. Purpose: Retrospective assessment of post-operative complications in patients >75 years who underwent open/laparoscopic nephrectomy/nephroureterectomy for renal diseases and grading the post-operative complications according to the Clavien-Dindo classification. Materials and Methods: Retrospective review of case notes was performed in patients >75 years who underwent a laparoscopic/open nephrectomy/nephroureterectomy between 2000 and 2008. Post-operative complications were graded according to the Clavien-Dindo classification. Results: A total of 54 patients >75 years underwent nephrectomy/nephroureterectomy. 29 patients had laparoscopy and 25 had open surgery. Fifty one patients had a malignancy and 3 had benign diseases. Grade I, II, IIIa, IIIb and IVa were 25.6%, 41.1%, 7.7%, 7.7% and 17.9% respectively. No significant difference was noted in the 2 groups Conclusions: We believe that in elderly patients, laparoscopic surgery can be offered safely without significantly increasing the surgical risks. The Clavien-Dindo classification is easy to use and effectively applied to categorize post-operative complications associated with nephrectomy/nephroureterectomy in elderly population. However, this system needs slight modification to incorporate intra-operative complications and large studies are needed to validate and standardize this classification for all urological procedures.

Abstract
BACKGROUND Nephroureterectomy (NU) represents the primary management for patients with nonmetastatic upper tract urothelial carcinoma (UTUC). Either an open NU (ONU) or a laparoscopic NU (LNU) may be considered. Despite the presence of several reports comparing perioperative and cancer-control outcomes between the two approaches, no reports relied on a population-based cohort. OBJECTIVES Examine intraoperative and postoperative morbidity of ONU and LNU in a population-based cohort. DESIGN, SETTING, AND PARTICIPANTS We relied on the US Nationwide Inpatient Sample (NIS) to identify patients with nonmetastatic UTUC treated with ONU or LNU between 1998 and 2009. Overall, 7401 (90.8%) and 754 (9.2%) patients underwent ONU and LNU, respectively. To adjust for potential baseline differences between the two groups, propensity-score-based matching was performed. This resulted in 3016 (80%) ONU patients matched to 754 (20%) LNU patients. INTERVENTION All patients underwent NU. MEASUREMENTS The rates of intra- and postoperative complications, blood transfusions, prolonged length of stay (pLOS), and in-hospital mortality were assessed for both procedures. Multivariable logistic regression analyses were performed within the cohort after propensity-score matching. RESULTS AND LIMITATIONS For ONU versus LNU respectively, the following rates were recorded: blood transfusions, 15% versus 10% (p<0.001); intraoperative complications, 4.7% versus 2.1% (p=0.002); postoperative complications, 17% versus 15% (p=0.24); pLOS (≥5 d), 47% versus 28% (p<0.001); in-hospital mortality, 1.3% versus 0.7% (p=0.12). In multivariable logistic regression analyses, LNU patients were less likely to receive a blood transfusion (odds ratio [OR]: 0.6; p<0.001), to experience any intraoperative complications (OR: 0.4; p=0.002), and to have a pLOS (OR: 0.4; p<0.001). Overall, postoperative complications were equivalent. However, LNU patients had fewer respiratory complications (OR: 0.4; p=0.007). This study is limited by its retrospective nature. CONCLUSIONS After adjustment for potential selection biases, LNU is associated with fewer adverse intra- and perioperative outcomes than ONU.

Abstract
PURPOSE Previous reports of the morbidity of renal surgery have been primarily from academic tertiary referral centers and, thus, they may not reflect general clinical practice. We determined the effect of age and comorbidity on in-hospital surgical morbidity for radical and partial nephrectomy on a population level. MATERIALS AND METHODS Data were obtained from a Canadian national discharge abstract database. From April 1998 to March 2008 information was available on 20,286 radical and 4,292 partial nephrectomies. Complications were identified using specific ICD-9 and 10 diagnosis and procedure codes. Complication rates were estimated by procedure type and by various explanatory variables, including patient age and Charlson comorbidity score. Multivariate logistic regressions were constructed for radical and partial nephrectomy to determine associations between explanatory variables and complications. RESULTS Overall complications developed in 34.1% of radical and 34.3% of partial nephrectomy cases. Patients were more likely to have cardiac, respiratory, vascular and surgical complications after radical nephrectomy while they were more likely to experience genitourinary and nephrectomy specific complications after partial nephrectomy. On multivariate logistic regression after radical and partial nephrectomy complications increased with age and Charlson score. After adjusting for other covariates patients with a Charlson score of greater than 2 were approximately 6 times more likely to experience a complication than patients with a Charlson score of 0 for radical and partial nephrectomy (OR 6.22, 95% CI 5.18-7.48 and OR 5.68, 95% CI 3.72-8.66, respectively). CONCLUSIONS In our population based study radical nephrectomy and partial nephrectomy were associated with higher morbidity than previously reported, particularly in the elderly population and in patients with comorbidity.

Abstract
In light of the aging population and the high incidence of urologic malignancies in the elderly in the United States, we review issues surrounding radical urologic surgery in the elderly. Specifically, we examine the safety, efficacy, techniques, and special concerns related to elderly patients. We found in multiple series that well selected, elderly patients can safely undergo major, extirpative urologic surgery with acceptable morbidity, comparable to their younger counterparts. Tools, such as the ASA score, Karnofsky index, and Charlson index may help guide patient selection and counseling.

Abstract
OBJECTIVE To describe our experience with laparoscopic renal surgery (LRS) in the octogenarian. Octogenarians are generally suboptimal surgical candidates but the recent upsurge of minimally invasive options for the management of kidney lesions, such as laparoscopic excision, cryoablation and radiofrequency ablation (RFA), have changed that perception. PATIENTS AND METHODS In all, 26 patients aged >or=80 years underwent LRS at Brown University and the University of Wisconsin between 2000 and 2006. Demographic information, anatomical location, tumour stage, comorbidities, type of laparoscopic approach, management and outcomes were assessed. Complications during and after LRS, hospital stay, analgesia requirements and return to normal activity were analysed. RESULT The mean age of the patients was 81 years. The procedures performed included hand-assisted laparoscopic partial nephrectomy (three patients), hand-assisted laparoscopic radical nephrectomy (10), hand-assisted laparoscopic nephroureterectomy (four), laparoscopic-assisted cryoablation (seven), laparoscopic RFA (one), and laparoscopic unroofing of a renal cyst (one). The mean (range) follow-up was 40 (8-84) months. The mean American Society of Anesthesiologists score was 2.5. The average hospital stay was 5.6 days and the mean time to normal activity after discharge was 19 days. There were two major and five minor complications. Nineteen of 22 patients evaluable had no evidence of disease at the last follow-up. The three deceased patients died of unrelated causes. CONCLUSION LRS in the octogenarian is safe to perform in patients with multiple comorbidities. The major and minor complication rates were 7% and 19%, respectively. Recent trends show that ablative procedures are being performed more commonly than surgical excision in this age group.

PURPOSE To our knowledge the outcomes of laparoscopic renal oncological surgery in patients with major aortic and/or inferior vena caval pathology are unknown. We present our experience spanning an 8-year period. MATERIALS AND METHODS From March 1998 to October 2006, 1,826 laparoscopic renal procedures were performed for tumor. Of these patients 66 (3.6%) had major abdominal aortic or vena caval pathology concomitantly. Demographics, specific entities of the vascular disease, and intraoperative and postoperative data were reviewed. RESULTS A total of 66 patients had a history of abdominal aortic disease (54), vena caval disease (9) or both (3). Of the patients 85% had 3 or greater comorbidities, 88% had an American Society of Anesthesiologists score of 3 or greater and 88% were on chronic anticoagulation therapy. A total of 27 patients (41%) had undergone prior surgical treatment for vascular pathology. Laparoscopic renal surgery, which was transperitoneal in 25 cases and retroperitoneal in 41, included radical nephrectomy in 20, partial nephrectomy in 17 and cryoablation in 29. Open conversion was performed in 3 patients (5%). There were 3 intraoperative (5%) and 9 postoperative (14%) complications. One patient died of pulmonary sepsis. There was no statistically significant difference in perioperative outcomes between the aortic and vena caval disease groups. The retroperitoneal approach was associated with less blood loss and shorter operative time (p = 0.0003 and 0.004, respectively). CONCLUSIONS Laparoscopic surgery for renal tumor in the presence of aortic or vena caval disease is safe and feasible. Considerable prior laparoscopic experience is necessary when treating these patients at high risk.

Abstract
OBJECTIVES Laparoscopic surgery for kidney treatment is a common procedure. However, the efficacy of this procedure in patients with several comorbidities has not been well investigated. We conducted a retrospective comparison of results of laparoscopic surgery between patients with several comorbidities and patients with no comorbidity to access the efficacy and safety of this procedure. METHODS The subjects were 20 patients with three or more comorbidities (group A) and 46 patients with less than three comorbidities (group B). These 66 patients were 48 men and 18 women with a mean age of 62.3 years (age range, 24-83 years). The data from these two groups were compared for American Society of Anesthesiology (ASA) physical status score, previous surgical history, duration of surgery, estimated blood loss, tumor size, complications during and after surgery, conversion rates, time to oral intake, and length of hospital stay. RESULTS The initial ASA score and age were significantly higher for the patients with comorbidities (P < 0.0001, P = 0.0008, respectively). All other variables before, during, and after surgery were similar for both laparoscopic groups. However, the incidence of atelectasis of laparoscopy was higher than that of open surgery. CONCLUSIONS Laparoscopic nephrectomy for patients with comorbidities is safe and minimally invasive. Further investigation to prevent atelectasis is necessary.

Abstract
PURPOSE We assessed the influence of HARDN on residual donor kidney and allograft function, invasiveness and morbidity in elderly living donors. MATERIALS AND METHODS A total of 89 living donors underwent nephrectomy before September 2004 at our institution. The 18 donors who were 65 years or older included 4 of 27 with ODN and 14 of 62 with HARDN. RESULTS In older (65 years or older) donors mean operative time, mean blood loss and warm ischemia time in the HARDN group did not differ from those in the ODN group. None of the donors had major complications. Older donors with HARDN had a tendency toward a shorter hospital stay than those with ODN. Postoperative serum creatinine in older donors with HARDN was higher than that in younger donors with HARDN, while there was no difference in postoperative serum creatinine between older donors with HARDN and those with ODN. The frequency of allograft losses tended to be higher in older than in younger kidneys (4 of 18 vs 5 of 71, p = 0.054). However, most allograft losses did not seem to be related to surgical technique. CONCLUSIONS Although further studies, especially with long-term followup, are necessary, HARDN is suggested to be safe and minimally invasive surgery even in elderly donors and to be comparable to open surgery in terms of morbidity, the residual donor kidney and allograft function.

Abstract
In this article, we review the different surgical approaches to carry out radical laparoscopic nephrectomy: transperitoneal approach, retroperitoneal approach and hand-assisted approach. We describe the advantages and drawbacks of each alternative and summarize the most important references in the medical literature. In spite of this being a relatively new surgical approach, less than 15 years old, it has become a standard treatment and, today, is considered as the elective surgical treatment for T1 and T2 renal tumours in many centres.

Abstract
PURPOSE To evaluate the efficacy of hand-assisted laparoscopic radical nephrectomy (HALRN) in patients with localized stage T(1)/T(2) renal-cell carcinoma, we analyzed the clinical results of our patients treated in this way. PATIENTS AND METHODS From March 1999 to March 2003, a total of 96 patients aged 28 to 86 years (mean 61 years) with clinical stage T(1)/T(2)N(0)M(0), pathologically confirmed renal-cell carcinoma underwent HALRN. The outcomes were compared with those of open radical nephrectomy, which was performed in 86 patients from November 1991 to February 1999 in our institution. Kaplan-Meier analysis was used to analyze survival. RESULTS Ten patients (10.4%) had perioperative complications. During a mean follow-up of 25 months (range 6-54 months), no patients died of the cancer, although three patients had metastatic disease. The 4-year disease- free and overall survival rates were 88% and 100%, respectively. Seventy-eight patients who underwent open radical nephrectomy were followed for 38 to 156 months (median 86 months). Seventy-three survived without any recurrent disease, five survived with metastasis, and no patient died of metastatic disease. The 4-year disease-free and overall survival rates were 93% and 100%, respectively. CONCLUSIONS Hand-assisted laparoscopic surgical management of T(1)/T(2) renal-cell carcinoma is feasible and safe. At our institution, HALRN confers long-term oncologic effectiveness equivalent to that of open radical nephrectomy.

Abstract
Advancements in minimally invasive instrumentation and technique have provided the impetus to performing urologic procedures with reduced perioperative morbidity, shorter hospital stays, and, most importantly, efficacious oncologic results. At multiple centers of excellence, laparoscopic nephroureterectomy (LNU) has evolved into a new standard for the management of upper-tract transitional-cell carcinoma (TCC) that is not amenable to endoscopic resection. An LNU may be performed via a transperitoneal or retroperitoneal approach together with excision of the distal ureter and a bladder cuff. Analysis of present-day studies comparing LNU with open techniques demonstrates equivalent oncologic outcomes. In addition, those patients undergoing LNU fare better than their counterparts having open surgery with respect to hospital stay, analgesic requirements, and convalescence. With multiple options for excision of a cuff of bladder, a consensus has not been established. However, LNU has emerged as the new standard of care for the treatment of upper- tract TCC. Review of the techniques and outcomes of LNU from the minimally invasive urology community are described.

Abstract
BACKGROUND Laparoscopic renal surgery is now accepted within the urological community and its indication is extended to oncological operation. The oncological outcome and survival of patients undergoing laparoscopic radical nephrectomy for clinically localized renal cell carcinoma were evaluated. METHODS From October 1998 to July 2003, 100 patients underwent laparoscopic radical nephrectomy for clinically localized renal cell carcinoma. All operations were performed by transperitoneal approach with early vascular control. Perioperative events and pathological data were recorded prospectively. Patients were followed up by clinical examination, chest radiograph, ultrasonography and/or computed tomography where appropriate. RESULTS The median age of patients was 61 years. Median operating time was 120 min and blood loss was 100 mL. There were five open conversions. There was no perioperative mortality but 11 patients had complications. Resection margins were clear in all but one patient. The median tumour size was 4.6 cm. The median follow-up time was 30 months. All patients survived up to the date of review. No patient developed port-site recurrence but two patients had recurrence at the renal bed 1 year after the operation. Five patients developed distant metastases involving liver, lung and bone. CONCLUSION Laparoscopic radical nephrectomy is a safe and efficacious treatment option for clinically localized renal cell carcinoma. The intermediate-term oncological outcome appears favourable.

Abstract
OBJECTIVE To evaluate objective alterations of body configuration in patients who treated with retroperitoneoscopic nephrectomy (RN) and retroperitoneoscopy-assisted nephroureterectomy (RAN). PATIENTS AND METHODS Twenty-six patients who had RN and 23 RAN were eligible for the study. Abdominal computed tomography films before and after surgery were evaluated. The intra-abdominal content surrounded by the vertebral bones and the muscles forming the trunk of the body were divided into four subspaces. The areas of these four portions were measured, and the ratio of occupation of each portion calculated before compared with that obtained after surgery. RESULTS While RAN had little impact on body configuration, RN significantly affected it; after RN the total area and area of ventral subspaces decreased homogeneously throughout the L2-L4 levels. The ipsilatero-dorsal subspace had a marked cranial decrease in area and no caudal alteration. CONCLUSIONS While RAN has little effect on body configuration, RN has a significant effect, as measured objectively. Continuing the skin incision between ports and muscle splitting to extract the specimen is probably responsible for the difference between the findings of RAN and RN.

Abstract
OBJECTIVE To evaluate the efficacy and outcome of laparoscopic radical nephrectomy (LRN) in patients aged >75 years, and to compare the results with those obtained from patients younger than this undergoing laparoscopic surgery for the same indication. PATIENTS AND METHODS From a retrospective review of 33 patients aged >75 years undergoing LRN, 28 were for tumour. A group of 28 consecutive patients aged <75 years undergoing laparoscopy for the same indication were used for comparison. The two groups were compared for American Society of Anesthesiology (ASA) physical status score, comorbidity, previous surgical history, operative duration, estimated blood loss, tumour size, complications during and after surgery, conversion rates, time to oral intake and drain removal, perioperative mortality and hospital stay. RESULTS Only the initial ASA score was significantly higher for the older patients. All other variables before, during and after surgery were similar for both groups. CONCLUSIONS The final outcome of laparoscopic surgery in elderly patients was as promising as in their younger counterparts. Therefore, elderly patients should not be excluded from LRN, even though they usually present with more comorbidities.

Abstract
Since the first procedure by Clayman and colleagues in 1990, laparoscopic nephrectomy has been performed at multiple institutions worldwide and is an accepted approach for benign and malignant renal pathology. We retrospectively compared the outcomes of laparoscopic nephrectomy for renal pathology in patients older than and less than 65 years of age. Data were collected for all patients undergoing elective nephrectomy (simple, radical, and nephroureterectomy) for renal pathology between November 2000 and June 2003. A total of 94 laparoscopic nephrectomies (62 hand-assisted, 32 totally laparoscopic) for renal disease were performed. Indications for surgery included renal cell carcinoma (63), transitional cell carcinoma (7), hypertension (9), chronic pyelonephritis (6), nonfunctioning kidney (4), complex cyst (3), and polycystic kidney disease (2). There were 33 elderly patients (≥65 years) and 61 adult patients (<65 years). The elderly group had a mean operative time (238 min vs 234.3 min; P = 0.89) and blood loss (88.5 mL vs 149.8 mL; P = 0.68) similar to the adult group. Likewise, the incidence of perioperative complications was no different between the two groups (intra-op: 3.0% vs 0%; P = 0.35 / post-op: 21.2% vs 16.4%; P = 0.56). The length of hospitalization was longer in the elderly population (5.7 days versus 5.0 days; P = 0.01) compared to the younger adult group. Laparoscopic nephrectomy is well tolerated in the elderly population. For all surgical indications, the use of a minimally invasive approach confers operative times, blood loss, and morbidity that are comparable to those of younger patients. Yet, length of stay remains longer for elderly patients undergoing nephrectomy.

Abstract
OBJECTIVES To perform a retrospective analysis to determine the operative morbidity in patients with substantial comorbidities requiring renal surgery. Increasing numbers of patients requiring renal surgery are presenting with substantial comorbidities, such as diabetes mellitus, chronic obstructive pulmonary disease, and cardiovascular disease. METHODS The American Society of Anesthesiologists (ASA) physical status classification was used to define perioperative risk. Of 1087 patients who underwent nephrectomy between 1989 and 2001, 237 patients were classified as ASA classification 1 or 2 (low risk), 297 were ASA classification 3 (intermediate risk), and 17 were ASA classification 4 (high risk). RESULTS No statistically significant differences were found among the low-risk, intermediate-risk, or high-risk patients with regard to 1997 T stage distribution, mean tumor size, vascular and/or inferior vena cava involvement, percentage of partial nephrectomy, adjacent organ resection, or preoperative hemoglobin. Intermediate-risk patients did have a greater estimated blood loss (946 versus 739 mL, P = 0.05), leading to greater transfusion rates (42% versus 28%, P = 0.001). However, no increase occurred in intraoperative or postoperative morbidity. High-risk patients also had greater transfusion rates, as well as a greater rate of complications occurring more than 24 hours after surgery. CONCLUSIONS Partial or radical nephrectomy can be offered to patients with comorbid conditions. ASA classification 3 patients are more likely to require transfusion. This may have been a result of a lower threshold to transfuse patients with preoperative morbidities. However, the perioperative and postoperative complication rates were similar to those of low-risk patients. Not surprisingly, high-risk patients had greater rates of transfusions and complications.

Abstract
PURPOSE Few reports in the urological literature have focused on the growing population of elderly (65 years or older) patients. Coexistent medical conditions, which are more prevalent in elderly individuals, can confound results of outcome studies in this population. This single center, retrospective study was done to determine whether age and comorbidity are predictors of outcome in patients undergoing laparoscopic renal and adrenal surgery. MATERIALS AND METHODS From 1997 to 2001 laparoscopic radical nephrectomy, partial nephrectomy, nephroureterectomy and adrenalectomy were performed in 399 consecutive adults. Patient demographics and preoperative, intraoperative and postoperative parameters were extracted from a prospectively designed computerized database. Risk stratification was based on preoperative American Society of Anesthesiologists (ASA) score. Additional risk stratification was constructed using the Charlson comorbidity index. Univariate and multivariate analyses were also performed. RESULTS Age 65 years or older was not associated with an increased incidence of intraoperative, postoperative or late operative complications on univariate or multivariate analyses. However, patients 65 years or older were hospitalized significantly longer than those younger than 65 years (43 vs 24 hours, p = 0.02). Blood loss and the requirement for blood transfusion were associated with longer operative time, a higher incidence of intraoperative and postoperative complications on univariate analysis, and longer hospitalization. No association of blood loss with postoperative complications was noted on multivariate analysis. Patients with a higher ASA score were more likely to receive blood transfusion. On univariate analysis risk stratification using the ASA score and the Charlson comorbidity index was not associated with intraoperative or postoperative complications. However, on multivariable analysis patients with the lowest indexes were less likely to experience postoperative complications than those with the highest indexes (less than vs greater than 3, p = 0.04). The comorbidity index had a marginal association with the incidence of late complications (p = 0.06). CONCLUSIONS Laparoscopic renal and adrenal surgery in patients 65 years or older is well tolerated. Age 65 years or older is predictive of a significantly increased hospital stay of approximately 1 day after major renal and adrenal laparoscopic surgery and it does not appear to increase independently the risk of intraoperative, postoperative or late operative complications.

Abstract
OBJECTIVE To compare the outcome in contemporaneous groups of patients undergoing hand-assisted laparoscopic radical nephrectomy (HALRN) or open (flank) radical nephrectomy (ORN), as many series worldwide have confirmed the feasibility and advantages of LRN in managing renal cell carcinoma (RCC). PATIENTS AND METHODS We retrospectively evaluated 44 patients who underwent radical nephrectomy for RCC from 1999 to 2001, 22 by HALRN and 22 by ORN, through an extraperitoneal 11th or 12th rib flank incision. Standard perioperative variables were assessed; a validated questionnaire was also sent to each patient after surgery, allowing them to report their overall satisfaction and the period needed for them to return to both routine and full activities. The outcomes of HALRN and ORN were compared using Wilcoxon rank-sum analysis. RESULTS There was a statistically significant difference between HALRN and ORN in operative duration, length of hospital stay, total narcotic requirement, pain scores at 1 week and 1 month after surgery, and the time to resume routine and full activity, with all variables (except operative duration) lower in the HALRN group. There were no significant differences between the groups in pain at 1-3 days, estimated blood loss or overall satisfaction. CONCLUSION Compared with ORN, HALRN is associated with lower narcotic requirement, pain scores, a shorter hospital stay and earlier resumption of routine and full activities. However, several obstacles remain, including increased operative duration and the increased equipment costs.

Abstract
To evaluate retrospectively our laparoscopic adult donor nephrectomy experience for pediatric transplantation. Since February 1995, 7 adult donors have undergone laparoscopic donor nephrectomy for pediatric renal transplantation (recipients younger than 18 years and weighing less than 30 kg). The outcomes of these donors and pediatric recipients were evaluated. The 7 laparoscopic renal donors had a median operative time of 306 minutes, median allograft warm ischemia time of 275 seconds, median blood loss of 200 mL, median hospital stay of 3 days, and 14.2% overall complication rate. No graft loss or patient mortality occurred. The pediatric recipients of the laparoscopic live-donor allografts had a median creatinine clearance level of 52.1, 52.1, 44, and 41.1 mL/min at 3, 6, 12, and 18 months, respectively. The overall complication rate was 14.2%. The 1 and 2-year graft survival rates were 100%. No mortality occurred in the pediatric recipients. Laparoscopic donor nephrectomy is well tolerated by the adult donors and appears to provide acceptable recipient and allograft outcomes in the pediatric population.

Abstract
PURPOSE Nephron sparing surgery provides effective therapy in patients with a solitary sporadic renal tumor 4 cm. or less and a normal contralateral kidney. Laparoscopic radical nephrectomy has been applied as a newer alternative therapy in these patients. These 2 contemporary approaches represent divergent treatment alternatives at centers where laparoscopic nephron sparing surgery is not offered. We compared the short-term and long-term impact of these 2 treatment modalities in patients with a sporadic localized solitary renal tumor 4 cm. or less and a normal opposite kidney. MATERIALS AND METHODS A retrospective review of a contemporary series of patients (1996 to 2001) who underwent open nephron sparing surgery and met study inclusion criteria was performed and compared with a similar cohort (1997 to 2001) that underwent laparoscopic radical nephrectomy. Only patients with a single renal tumor of 4 cm. or less, normal serum creatinine less than 1.5 mg./dl. and a normal contralateral kidney were included in analysis. The 2 groups were compared in regard to demographic, clinical and pathological variables using parametric and nonparametric tests. Linear regression analysis was done to compare the percent change in serum creatinine, while adjusting for demographic and clinical variables, and followup. RESULTS A total of 35 patients who underwent laparoscopic radical nephrectomy and 82 who underwent open nephron sparing surgery met study inclusion criteria. Mean patient age in the laparoscopic group was significantly greater (67.3 versus 56.2 years, p <0.001), mean American Society of Anesthesiologists class score was higher (p = 0.04) and mean tumor size was greater (3.1 versus 2.6 cm., p = 0.003) than in the nephron sparing group. The laparoscopic group had significantly decreased mean blood loss (100 versus 200 ml., p <0.001), hospital stay (1 versus 5 days, p <0.001), narcotic use (16.5 versus 224 mg., p <0.001) and operative time (184.4 versus 216.2 minutes, p <0.007) compared with the nephron sparing group. Patients who underwent nephron sparing surgery experienced less postoperative deterioration in renal function, as measured by the percent increase in serum creatinine postoperatively (0% versus 25%, p <0.001). The results of regression analyses at 4 and 6 months of followup indicated that open nephron sparing surgery is associated with significantly lower serum creatinine than laparoscopic radical nephrectomy after adjusting for demographic and clinical variables, and followup. CONCLUSIONS Open nephron sparing surgery and laparoscopic radical nephrectomy are relatively recent and significant developments for treating patients with renal cell carcinoma and they represent accepted standards of care in those with a small renal mass and normal contralateral kidney. In patients presenting with a sporadic solitary renal tumor of 4 cm. or less and a normal contralateral kidney the significant short-term and intermediate term benefits of the laparoscopic approach must be weighed against the long-term advantage of better renal function associated with open nephron sparing surgery. The distinct advantages of these 2 approaches may ultimately be realized with the standardization of laparoscopic partial nephrectomy.

Abstract
OBJECTIVES To evaluate retrospectively the outcome of laparoscopic donor nephrectomy in patients aged 65 years or older, because data regarding tolerance profile and renal allograft outcome of laparoscopic donor nephrectomy in the elderly patient are lacking. METHODS Since February 1995, 6 patients aged 65 years or older underwent laparoscopic donor nephrectomy for living-related renal transplantation. Patient demographic, intraoperative, and postoperative parameters, as well as renal allograft outcome, were evaluated. RESULTS The median donor age was 69.5 years (range 65 to 74), and the median American Society of Anesthesiologists score was 2 (range 2 to 3). The median operative time was 240 minutes (range 183 to 298), with a median blood loss of 300 mL (range 150 to 400). No intraoperative complications or open conversions occurred. Postoperatively, the median time to resumption of oral intake was 1 day (range 1 to 3), and the median hospital stay was 3 days (range 2 to 4). The median narcotic analgesic requirement was 17 mg (range 11 to 27) morphine sulfate equivalent, and the median convalescence was 2 weeks (range 1 to 4). The 1-year renal allograft survival was 100% (n = 6). CONCLUSIONS Laparoscopic donor nephrectomy is well tolerated by the elderly patient and provides satisfactory patient and renal allograft outcome. Although our sample size was small, it appears that laparoscopy is an acceptable modality for renal donation in the elderly population.

Abstract
Until recently, malignancies of the kidney and ureter were managed with open radical surgery. Over the last decade the urologic community has adopted the skill of laparoscopic surgery for the treatment of these tumours. Parenchymal sparing procedures have become the standard of care in the treatment of selected patients with renal and ureteral tumours and many of these surgical procedures can be performed laparoscopically or ureteroscopically. Due partly to necessity and partly to the advancement of technology, renal and ureteral sparing procedures have become commonplace for definitive treatment and palliation of these tumours. The morbidity of such procedures is significantly less than for open surgery and the future of urologic minimally invasive surgery appears secure. This review article is aimed at updating the reader in the most recent advances in these techniques.

Abstract
OBJECTIVE To report the experience in one centre of the efficacy and safety of retroperitoneal laparoscopic procedures (RLPs). PATIENTS AND METHODS During 1991-2000, 351 RLPs using the balloon technique were undertaken in 340 patients (mean age 34.9 years, range 4-74); the details and outcome were reviewed. Initial access was by the mini-open digital dissection technique in 152 and by the closed percutaneous technique in the remaining 199 procedures. Patients had not undergone previous retroperitoneal procedures, except for nine who had a percutaneous nephrostomy and eight ipsilateral abdominal surgery. There were 172 renal, seven adrenal, 97 ureteric, 50 gonadal, 13 lymphatic system, three vesical, two autonomic nervous system and seven vertebral RLPs. Nitrous oxide was used for pneumo-insufflation in 103 procedures, instead of CO2. RESULTS The RLP was successful in 318 of the 351 procedures (90.6%). The operative duration was 0.5-5.5 h, depending on the difficulty of the procedure and the presence or absence of adhesions. The overall incidence of complications was 12.9%, but decreased to 9% for the last 100 procedures. There were only five major complications, e.g. avulsion of the ureter, torn renal pelvis, colonic injury and severe hypotension, but none were related to balloon dissection. The mean blood loss was 37.7 mL and the reason for transfusion in three patients was not operative blood loss but displacement of the ligature in two and severe hypotension after removing a phaeochromocytoma in one. The mean duration of analgesic use was 2.5 days, the hospital stay 3 days and return to work 14 days. CONCLUSION Retroperitoneal laparoscopy using the balloon technique is a reasonably safe, efficient and reliable minimally invasive procedure. The efficiency, efficacy and safety of RLPs depend more on experience than on the type of access technique, type of balloon or medium used to inflate the balloon. Balloon rupture causes no tissue damage, and expansion to approximately 800 mL in adults is safe if the retroperitoneal space has not previously been invaded. The use of nitrous oxide for pneumo-insufflation in the retroperitoneal space is safe if proper precautions are taken.

Abstract
Objectives. To report a modified approach for hand-assisted laparoscopic nephroureterectomy (HALNU).Methods. Seven patients with localized transitional cell carcinoma of the upper urinary tract underwent unilateral HALNU. Patients were placed in a 60 degrees oblique position during the entire procedure. Via a 7-cm Gibson incision on the lesion side, the distal ureterectomy and bladder cuff excision were done by an open method without opening the bladder. Then, with the surgeon's hand inserted into the peritoneal cavity by way of the same wound, HALNU was performed with two to three additional laparoscopic ports. The perioperative parameters were compared with those of 15 cases of conventional open nephroureterectomy.Results. Patients in the HALNU group had significantly less mean blood loss (140 versus 455 mL) and earlier resumption of oral intake (33 versus 61 hours), required fewer narcotics (38 versus 70 mg of morphine sulfate equivalent), and were discharged earlier (7.33 versus 9.1 days), with a faster convalescence to normal activity (3.7 versus 5.6 weeks; all P < 0.05). The total mean surgical time was 3.7 hours for the HALNU group.Conclusions. Our approach used the same incision to both excise the distal ureter and apply the hand-assist device. It also preserved the benefits of the minimal invasiveness of laparoscopic surgery compared with its open counterpart.

Abstract
BACKGROUND AND PURPOSE For patients with upper tract transitional-cell carcinoma (TCC), nephroureterectomy with removal of a bladder cuff is the standard of care. Historically, it has been performed using two incisions or one large incision extending from the lateral flank to the symphysis pubis. We describe an alternative using endoscopic management of the bladder cuff combined with hand-assisted laparoscopic (HAL) nephroureterectomy. We compared our results using these minimally invasive advances with those of a contemporary open nephroureterectomy series. PATIENTS AND METHODS Between May 1998 and June 1999, we performed 11 HAL nephroureterectomies with endoscopic management of the bladder cuff for the treatment of upper tract TCC. The results were compared with those in a contemporary series of 11 patients undergoing the traditional open operation at our institution. The patient age, male:female ratio, and ASA classification were similar in the two groups. Intraoperative measures considered were operative time, estimated blood loss, need for transfusion, complications, specimen weight and volume, pathologic stage and grade of the tumor, and the status of the surgical margins. Postoperative endpoints were time to sustained fluid intake; epidural, parenteral, and oral narcotic requirements; length of stay; and complications. Follow-up, specifically disease recurrence and overall survival, was recorded. RESULTS The mean operative time was 291 minutes for HAL v 232 minutes for the open operation (P = NS). The average blood loss was 144 v 311 mL (P = 0.04), the mean specimen weight 368 v 392 g (P = NS), and the mean specimen volume was 630 v 693 cc (P = NS). No patient in the HAL group had a positive surgical margin, but one patient in the open surgery group did. The time to sustained fluid intake postoperatively averaged 1.4 v 2.3 days for the HAL and open groups, respectively (P = NS). The epidural narcotic requirement was 0 v 2.7 days (P < 0.001), the mean parenteral narcotic requirement was 45 v 44 mg of morphine sulfate equivalent (P = NS), and the oral narcotic requirement was 5.8 v 16 tablets (P < 0.04). The average length of stay was 4.6 days for the HAL group v 6.1 days for the open group (P = 0.04). In both groups, 7 of the 11 patients (63%) were without evidence of disease with a mean follow-up of 13 (HAL) and 17 (open) months. CONCLUSIONS Hand-assisted laparoscopic nephroureterectomy with endoscopic management of the bladder cuff is an efficacious alternative to open surgery. The operative time, specimen weight and size, and risk of recurrence for the two procedures are similar. However, convalescence, as measured by pain medication requirements and length of stay, is significantly better with laparoscopy. Longer follow-up with larger numbers of patients is in progress.

Abstract
BACKGROUND AND PURPOSE Renal autotransplantation is an extensive open surgical operation consisting of two distinct procedures, live-donor nephrectomy and autotransplantation, and requiring two large skin incisions. Herein, we analyze the feasibility of performing the entire procedure laparoscopically. MATERIALS AND METHODS Renal autotransplantation was performed entirely laparoscopically in six female farm pigs. Following a left donor nephrectomy, intracorporeal renal hypothermia was achieved by intra-arterial perfusion of ice-cold solution through a 4F balloon catheter. During autotransplantation, the renal vessels were anastomosed intracorporeally to the previously prepared ipsilateral common iliac vessels in an end-to-side fashion. Laparoscopic freehand suturing (5-0 Prolene) and knot-tying techniques were employed exclusively. A staged contralateral native nephrectomy was performed in five animals. Postoperative follow-up included serial creatinine measurements, intravenous urography, aortography, and renal histologic examination. RESULTS The mean operating time was 6.2 hours (range 5.3-7.9 hours), the venous anastomosis time was 33 minutes (range 22-46 minutes), the arterial anastomosis time was 31 minutes (range 27-35 minutes), and the total iliac clamping time was 77 minutes (range 62-88 minutes). The total renal ischemia time was 68.7 minutes: warm ischemia 5.1 minutes, cold ischemia 33 minutes and rewarming 31 minutes. Serum creatinine concentrations remained stable: baseline 1.3 mg/dL, after autotransplantation 1.1 mg/dL, and after contralateral nephrectomy 1.6 mg/dL. Intravenous urography and aortography prior to euthanasia (N = 5) demonstrated prompt contrast uptake and excretion by the autotransplanted kidneys and patent arterial anastomoses, respectively. Histopathologic examination of the autograft demonstrated normal renal architecture. CONCLUSIONS Renal autotransplantation can be performed utilizing laparoscopic techniques exclusively. This study may form the basis for performance of complex urologic vascular procedures laparoscopically.

Abstract
OBJECTIVES Nephroureterectomy with removal of the bladder cuff is the standard of care for patients with upper tract transitional cell carcinoma. Historically, it has been performed using two separate incisions or one large incision extending from the lateral flank to the symphysis pubis. We describe an alternative technique using endoscopic and hand-assisted laparoscopic techniques and present our experience. METHODS During the past 18 months, 22 patients at two institutions underwent hand-assisted laparoscopic nephroureterectomy. In 19 patients, the distal ureter and bladder cuff were managed endoscopically. In 3 patients, the distal ureter and the bladder cuff were removed by an extravesical, laparoscopic technique. The intraoperative parameters assessed included operative time, estimated blood loss, specimen weight, surgical margin status, pathologic grade and stage, and acute complications. Postoperative endpoints included the time to sustained fluid intake, parenteral narcotic requirement (milliequivalents of morphine sulfate), oral narcotic requirement (number of tablets), length of stay, time until return to normal activity, and rate of tumor recurrence. RESULTS The average age of our patient population was 65 years (range 42 to 86), 10 patients were men and 12 were women, and the average American Society of Anesthesiologists classification was 2.2. All but 2 patients had their specimens removed en bloc. No intraoperative complications occurred. The average operative time was 272 minutes (range 190 to 440), and the average blood loss was 180 mL (range 50 to 400); no patient required a transfusion. The mean specimen weight was 457 g (range 190 to 1420). All 22 patients had negative surgical margins. Postoperatively, the time to sustained fluid intake averaged 2.1 days (range 1 to 7), the mean parenteral narcotic requirement was 55 mEq (range 12 to 107.8) of morphine sulfate, the mean oral narcotic requirement was 5.8 tablets (range 1 to 14), and the average length of stay was 4.1 days (range 3 to 14). One patient developed thrombophlebitis of the right external jugular vein from a central line and required 2 weeks of intravenous antibiotics. The mean time to return to normal activity was 19 days; the mean follow-up was 13 months. Six patients had disease recurrence: four low-grade, low-stage bladder tumors and two metastatic tumors. All patients were alive at 18 months. CONCLUSIONS Hand-assisted laparoscopic nephroureterectomy with endoscopic management of the bladder cuff is a viable and efficacious alternative to open nephroureterectomy. The technique allows the surgeon to perform an en bloc resection of the kidney, ureter, and bladder cuff without compromising oncologic principles. Patients benefit from a decrease in pain and hospital stay and quicker convalescence. Longer follow-up and comparative studies to standard open techniques are underway.
