Abstract
OBJECTIVE The aim of this study is to assess the safety and feasibility of the transperitoneal laparoscopic approach during nephron sparing surgery in patients with previous abdominal surgery. PATIENTS AND METHODS We retrospectively analyzed patients undergoing transperitoneal laparoscopic partial nephrectomy for renal masses. All patients had received a diagnosis of cT1a renal exophytic mass (⩽5 cm). Patients were divided into two groups, those with and without previous abdominal surgery. Patients with solitary kidney or major previous abdominal surgery were excluded in this study. The operative time, estimated blood loss, length of stay, surgical complications, and positive surgical margins were recorded to compare outcomes among two groups. RESULTS Of the 157 patients who were included in our study, 71 (45.3%) had a history of abdominal surgery (Group 1), while the remaining 86 (54.7%) had not (Group 2). Cholecystectomy was the most common previous surgery performed near the renal fossa. Patients with previous abdominal surgery experienced increased operative time (111.5 vs 83.2 min; p = 0.001). However, no statistically significant difference was found in estimated blood loss (122.1 vs 114.4 mL; p = 0.363), length of stay (4.1 vs 3.8 days; p = 0.465), rate of conversion to open surgery (2.8% vs 2.3%; p = 0.234), and rate of complications (p = 0.121). However, operative time (p = 0.003) and length of stay (p < 0.001) were greater in patients with versus those without previous open cholecystectomy. CONCLUSION Our results suggest that laparoscopic partial nephrectomy after minor previous abdominal surgery is safe and feasible in selected patients affected by renal masses with low nephrometry score. However, previous cholecystectomy results in an increased risk of conversion to open surgery and longer hospital stay in patients undergoing right laparoscopic partial nephrectomy.

Abstract
PURPOSE To review the current status of robotic-assisted laparoscopic surgical techniques for bladder neck procedures in children with incontinence secondary to neurogenic bladder. METHODS A comprehensive review of the literature on robotic-assisted bladder neck procedures was conducted, with a focus on articles published in the last 25 years. These data were subsequently compared to published series of open bladder neck procedures and published results from robotic-assisted bladder neck reconstruction series completed at our institution. RESULTS The principle bladder neck procedures for incontinence in pediatric patients with neurogenic bladder include: Artificial Urinary Sphincter, Bladder Neck Sling, Bladder Neck Closure, and Bladder Neck Reconstruction. Continence rates range from 60 to 100% with a lack of expert consensus on the preferred procedure (or combination of procedures). Robotic-assisted approaches are associated with longer operative times, especially early in the surgical experience, but demonstrate equivalent continence rates with potential benefits including low interoperative blood loss, improved cosmesis, and decreased intra-abdominal adhesion formation. CONCLUSIONS Robotic-assisted procedures of the bladder neck are safe, feasible, follow the same steps and principles as those of open surgery and produce equivalent continence rates. Robotic-assisted techniques can be adapted to a variety of bladder neck procedures and safely expanded to selected patients with the previous open abdominal surgery.

Abstract
Objectives: To describe a direct access partial nephrectomy technique through a transperitoneal working space (Roskilde technique).Materials and methods: Prospective single-center descriptive study between April 2015 and January 2017. The surgical outcomes are evaluated according to the Trifecta criteria (negative margins, warm ischemia time < 20 min and a Clavien-Dindo complication score < 3).Surgical procedure: The same access to the transperitoneal cavity as in a Standard transperitoneal Partial Nephrectomy was used. A direct access was established by incision of the peritoneum directly onto the renal fascia. The renal vessels and tumor were identified and the tumor removed with standard technique. The perinephric fat and peritoneum were then closed with a running suture.Results: In total, 122 patients underwent the Roskilde technique. The mean age was 62.2 years, the median Padua score was 12 (IQR = 9-12) and the median tumor size was 32 mm (IQR = 12-90). The median operative time was 101 min (IQR = 90-125). The trifecta achievement criteria goal was achieved in 116/122 (95%), with a median warm ischemia time of 8 min (IQR = 0-12).Conclusions: The Roskilde technique is safe and feasible. It can be performed on complex renal masses, and it seems to result in short operative times and high Trifecta achievement.Trial registration: None.

Abstract
Background Locally advanced and metastatic renal cell carcinoma (RCC) is associated with poor survival outcomes. The integration of presurgical systemic therapy with targeted molecular agents prior to surgical resection of RCC tumors has been utilized to improve on these outcomes. These agents may be associated with an increased risk of perioperative complications due to their action on angiogenesis and cell proliferation. Objective To examine the evidence for the incidence and severity of perioperative complications following presurgical targeted therapy for locally advanced or metastatic RCC. Methods We performed a systematic review of retrospective studies, prospective clinical trials, and meta-analyses using key search terms in PubMed and Medline. Studies were screened for eligibility and data were extracted by the authors. A qualitative analysis was performed and the complications for available targeted agents was reported. Results Retrospective analyses and small prospective trials indicate varying complication rates and types based on presurgical therapies. While some studies indicate a possible increase in wound-related complications, other studies did not show similar results. Additional unique complications reported include an increase in surgical adhesions. There was not any significant difference in overall or bleeding complications. Conclusions Overall, these studies demonstrate an acceptable level of surgical complications that should not discourage the clinician considering presurgical therapy. The results of pending trials looking at presurgical therapies will provide further information.

Abstract
PURPOSE We sought to evaluate the feasibility and safety of open or robotic radical prostatectomy (RP) after rectum, sigmoid, or colon surgery. MATERIALS AND METHODS Sixty-four patients with a median age of 65 years (range, 46-73 years) who underwent RP after previous pelvic surgery were included. Twenty-four patients (38%) underwent robotic RP and 40 patients (62%) underwent open RP. Bilateral lymph node dissection and nerve preservation were performed in 50 patients (78%) and 35 patients (55%), respectively. Variables evaluated included demographic characteristics, perioperative complications, and functional and oncological outcomes. The median hospitalization and follow-up periods were 2 days (range, 1-12 days) and 21 months (range, 1-108 months), respectively. RESULTS No conversions from robotic to open surgery were performed and there were no intraoperative complications. Surgical margins were positive in 13 patients (20%), seminal vesicle involvement was detected in 6 patients (9%), and lymph node involvement was found in 2 patients (3%). Postoperative complications included lymphocele in 1 patient, urethral stricture in 1 patient, and bowel obstruction and persistent bladder leakage in 2 patients. Eighty-eight percent of the patients were continent at 7 months and 80% of patients were able to achieve erection with or without medical aid. CONCLUSIONS Open or robotic RP can be done safely and effectively in patients who have previously undergone pelvic surgery. Although prior pelvic surgery of the large intestine was associated with increased morbidity, it should not be considered a contraindication for robotic or open RP.

Abstract
The formation of adhesions after abdominal surgery can lead to increased morbidity in children, increases the incidence of readmission, and may pose a significant challenge to subsequent surgical care over their lifetime. As the pathophysiology of peritoneal adhesion formation has been better understood, preventive strategies that minimize surgical trauma and contamination have been sought. Laparoscopy, over the past few decades, has become an increasingly utilized approach for many pediatric surgical problems and intuitively should have an advantage over open surgery in reducing adhesion formation. In this review, we examine the utility of laparoscopy in both the prevention and the treatment of intraabdominal adhesive disease in children.

Abstract
OBJECTIVE To compare the efficiency and safety of the transperitoneal approaches with retroperitoneal approaches in laparoscopic partial nephrectomy for renal cell carcinoma and provide evidence-based medicine support for clinical treatment. METHODS A systematic computer search of PUBMED, EMBASE, and the Cochrane Library was executed to identify retrospective observational and prospective randomized controlled trials studies that compared the outcomes of the two approaches in laparoscopic partial nephrectomy. Two reviewers independently screened, extracted, and evaluated the included studies and executed statistical analysis by using software STATA 12.0. Outcomes of interest included perioperative and postoperative variables, surgical complications and oncological variables. RESULTS There were 8 studies assessed transperitoneal laparoscopic partial nephrectomy (TLPN) versus retroperitoneal laparoscopic partial nephrectomy (RLPN) were included. RLPN had a shorter operating time (SMD = 1.001,95%confidence interval[CI] 0.609-1.393,P<0.001), a lower estimated blood loss (SMD = 0.403,95%CI 0.015-0.791,P = 0.042) and a shorter length of hospital stay (WMD = 0.936 DAYS,95%CI 0.609-1.263,P<0.001) than TLPN. There were no significant differences between the transperitoneal and retroperitoneal approaches in other outcomes of interest. CONCLUSIONS This meta-analysis indicates that, in appropriately selected patients, especially patients with intraperitoneal procedures history or posteriorly located renal tumors, the RLPN can shorten the operation time, reduce the estimated blood loss and shorten the length of hospital stay. RLPN may be equally safe and be faster compared with the TLPN.

Abstract
AIM To analyze the indications and outcome of laparoscopic nephrectomy for benign non-functioning kidneys in children. MATERIALS AND METHODS The data of all patients operated over a 10 year period was retrospectively analyzed. RESULTS There were 56 children, aged 4 months to 12 years with a male: female ratio of 2.3:1. The most common presentation in boys and girls was urinary tract infection (UTI) (61.5% and 47.05% respectively). Incontinence due to ectopic ureter was a close second in girls (41.17%). The most common underlying conditions were vesico-ureteric reflux (42.85%) and multicystic dysplastic kidney (23.2%). There were 6 nephrectomies, 4 heminephroureterectomies and the remaining nephroureterectomies. All children tolerated the surgery well. One patient underwent a concomitant cholecystectomy. The post-operative problems encountered were UTI (1), urine retention (1), pyonephrosis in the opposite kidney and development of contra-lateral reflux (1). All others had resolution of pre-operative symptoms with good cosmesis. CONCLUSIONS As per available literature, this appears to be the largest Indian series of pediatric laparoscopic nephrectomies for benign non-functioning kidneys. Laparoscopic approach gives excellent results provided pre-operative investigations rule out other causes for the symptoms with which the patient presents. Often it is not the kidney but the dilated dysplastic ureter which is the seat of stasis and infection or pain and therefore should be completely removed.

Abstract
BACKGROUND AND PURPOSE Treating patients with renal-cell carcinoma (RCC) after previous retroperitoneal surgery (renal or adrenal) is technically challenging. We present our initial experience with laparoscopic renal interventions (LRI) after previous open retroperitoneal surgery in patients needing ipsilateral renal intervention. We report on feasibility, functional and oncologic outcomes of LRI after previous open retroperitoneal surgery. PATIENTS AND METHODS We reviewed records of patients undergoing attempted laparoscopic or robot-assisted renal intervention after at least one previous open ipsilateral retroperitoneal surgery. We identified 34 patients who underwent 39 staged attempted LRI after 48 previous open ipsilateral renal or adrenal surgeries. The LRI included 20 minimally invasive partial nephrectomies (MIPN), 11 laparoscopic radiofrequency ablations (LRFA), and 8 laparoscopic nephrectomies (LTN). Demographic, perioperative, renal functional, and oncologic outcome data were collected. Statistical analyses were performed to identify risks for conversion to open surgery. RESULTS No attempted nephron-sparing procedure resulted in kidney loss. Overall conversion rate of the cohort was 28% and was highest in the MIPN group (40%). On univariate analysis, only multiple tumors that were treated significantly increased chances of open conversion (P<0.01). Subset analysis demonstrated similar rates of blood loss, operative times, and conversion rates in patients undergoing partial nephrectomy having previous open partial nephrectomy compared with previous open adrenal surgery only. There was no significant difference in preservation of renal function between MIPN and LRFA, with more than 85% of preoperative renal function preserved. Mean follow-up of 11.9 months (range 1-97.5 mos) metastasis-free survival and overall survival was 94.1% and 97%, respectively. CONCLUSIONS LRI after previous open ipsilateral retroperitoneal surgery is feasible. Repeated partial nephrectomy has the highest conversion risks among the laparoscopic renal interventions and appears to be independent of previous renal or adrenal procedure. Attempting repeated LRI for multiple tumors is a significant risk factor for open conversion. Renal functional and oncologic outcomes are encouraging at early follow-up.

Abstract
Abdominal adhesions are associated with increased postoperative complications, cost and workload. We performed a systematic review with statistical pooling to estimate the formation rate, distribution and severity of postoperative adhesions in patients undergoing abdominal surgery. A literature search was carried out for all articles reporting on the incidence, distribution and severity of adhesions between January 1990 and July 2011. Twenty-five articles fulfilled the inclusion criteria. The weighted mean formation rate of adhesions after abdominal surgery was 54 % (95 % confidence interval [CI] 40-68 %), and was 66 % (95 % CI 38-94 %) after gastrointestinal surgery, 51 % (95 % CI 40-63 %) after obstetric and gynaecological surgery and 22 % (95 % CI 7-38 %) after urological surgery. The mean overall severity score was 1.11 ± 0.98 according to the Operative Laparoscopy Study Group classification. Laparoscopic surgery reduced the adhesion formation rate by 25 % and decreased the adhesion severity score (laparoscopic; 0.36 ± 0.69 vs. open; 2.14 ± 0.84) for gastrointestinal surgery. Our results demonstrate that the incidence and severity of abdominal adhesions varies between surgical specialties and procedures. An increased awareness of adhesions can help in identifying the underlying mechanisms of adhesion formation and novel therapeutic approaches, while also improving the surgical consent process.

Abstract
BACKGROUND Laparoscopic renal cyst decortication often uses three-port incisions or single-port incision with three or four channels (laparoendoscopic single-site surgery). This article introduces a modified laparoendoscopic single-site surgery for the treatment of simple renal cysts: single-channel retroperitoneal laparoscopic decortication (SCRL) of a simple renal cyst. PATIENTS AND METHODS From January 2008 to December 2011, either SCRL or standard three-port-incision retroperitoneal laparoscopic decortication (SRL) was performed for the treatment of a simple renal cyst. The SCRL procedure was as follows. The patients were placed in the lateral decubitus position. A 1.2-cm horizontal skin incision was made over the midaxillary line, 3 cm above the iliac crest. The retroperitoneum working space was established. A 10-mm operative laparoscope, which is similar to a nephroscope, was introduced into the retroperitoneum cavity through a 1.1-cm port. The cyst was exposed and then sutured to help to suspend the cyst wall so that the cyst could be decorticated easily. Perioperative and follow-up data from SCRL and SRL were collected retrospectively. RESULTS Based on the cyst location as the major selection criterion, 92 cases were enrolled for further analysis. Of these, 38 patients were treated with SCRL, and 54 patients were subjected to SRL. No SCRL was converted to SRL, and no SRL was converted to open surgery. The operation time and the drain tube removal time in these two approaches were similar (P>.05), but the average duration of hospital stay in the SCRL group was shorter (P=.02). Six months after the surgery, renal ultrasound results showed that the diameter of the cyst in these two groups also had no significant difference (P>.05). CONCLUSIONS With appropriate selection of patients, the SCRL approach has the same efficacy with better cosmesis compared with SRL.

Abstract
AIM The impact of postsurgical intra-abdominal adhesions, which represent a considerable burden for patients and health services, is often underestimated. Various factors influence adhesion formation, including the surgical approach. This study aimed to further understand the condition by investigating surgeons' perceptions of adhesion formation, particularly differences after laparoscopic and open surgery, and by performing a selective literature review. MATERIALS AND METHODS South Asian surgeons attending endoscopy symposia in India and in Germany completed Likert-scale-based questionnaires on awareness of adhesion formation and associated consequences in gynecology. MEDLINE and PubMed were searched for articles published in 2000-2010 comparing laparoscopy and laparotomy in relation to adhesion formation. The results of the questionnaire study were then considered in view of findings from this review. RESULTS In total, 43.1% (97/225) of questionnaires were completed. Respondents considered that laparoscopy caused fewer adhesions than laparotomy for all gynecological procedures. Although they believed their knowledge of adhesion formation was satisfactory, they widely underestimated the risk, giving estimated rates of 12.5% after laparoscopy and 36.3% after laparotomy. Twenty-eight studies were identified in the review. Most concluded that laparoscopy was less likely to cause adhesions than laparotomy but further statistical analysis was precluded because so many different definitions and classifications of adhesions had been used. CONCLUSIONS The risk of adhesion formation was widely underestimated in the study group. Both the questionnaire study and the review concluded that laparoscopy results in less adhesion than laparotomy but further statistical comparison necessitates the development of standard definitions and classifications of adhesions.

Abstract
BACKGROUND Tyrosine kinase inhibitors (TKI) have dramatically changed the management paradigm of advanced renal cell carcinoma (RCC) and are increasingly being used preoperatively to achieve cytoreduction. OBJECTIVE To review our case series of post-TKI surgical procedures to add to the current perioperative efficacy and complication profile. MATERIALS AND METHODS Between October 2006 and February 2010, 14 cytoreductive nephrectomies, radical nephrectomies, and metastectomies were performed after neoadjuvant sunitinib or sorafenib for advanced RCC. During the same time frame, a control group of 73 consecutive patients underwent radical nephrectomy, cytoreductive nephrectomy, or metastectomy in the absence of prior systemic therapy. We compared the incidence of perioperative complications and outcomes after surgical procedures between the two cohorts. RESULTS Median preoperative renal mass size was 11 cm (6.7-24.2 cm). Primary tumor shrinkage was seen in 57%; median shrinkage was 18% (8%-25%). The median treatment period was 17 weeks, and the median time from TKI discontinuation was 2 weeks. Compared with a control group and after adjusting for confounding covariates, presurgical TKI use was not associated with a significant increase in perioperative complications (50% vs. 40%, P = 0.25) or perioperative bleeding (36% vs. 34%, P = 0.97) but was associated with increased incidence and grade of intraoperative adhesions (86% vs. 58%, P = 0.001; grade 3 vs. 1, P = 0.002). CONCLUSIONS Compared with the published reports, we observed less hemorrhagic and wound healing issues but a significant increase in incidence and severity of intraoperative adhesions, which can present a formidable technical challenge. Potential reasons for our lower complication rate could be increased time from TKI discontinuation to surgery, longer time to postoperative TKI re-initiation, increased use of preoperative angioembolization, and the lack of preoperative bevacizumab administration. Presurgical TKI therapy can permit effective surgical cytoreduction with a safety and complication profile equivalent to that of non-TKI-nephrectomy; however safety data continue to evolve, and preoperative TKI use requires further prospective investigation.

Abstract
OBJECTIVES To compare surgical and functional results of both surgical approaches to endoscopic partial nephrectomy. It is currently performed either by the transperitoneal (t) or the retroperitoneal (r) approach. METHODS This was a retrospective, matched-pair comparison of 105 patients who underwent either transperitoneal laparoscopic (Graz) or retroperitoneoscopic (Klagenfurt) partial nephrectomy for clinical T1a renal masses. RESULTS A total of 35 patients after transperitoneal laparoscopic and 70 patients after retroperitoneoscopic partial nephrectomy were included to this analysis after matching for age (T: 59.3 vs R: 60.1 a), preoperative glomerular filtration rate (GFR) (T: 93.2 vs R: 96.1 mL/min) and tumor size (T: 2.4 vs R: 2.5 cm). Nephrometry scores were comparable between groups and were low, medium, and high in 54.3%, 45.7%, and 0% (t) and 55.7%, 42.9%, and 1.4% (r) of patients (P = .9). Operative time (T: 139.3 minutes vs. R: 83.9 minutes; P < .001) and hospitalization (T: 7 days, R: 5 days; P < .001) were shorter in the retroperitoneoscopic group. Ischemia time (T: 24.3 minutes, R: 22.6 minutes) and postsurgical GFR (T: 86.6 vs R: 90.0 mL/min), postsurgical GFR-decrease (T: 7.1%, R: 6.2%, P = .9) and decline of hemoglobin (T: 17.1%, R: 16.6%) were comparable. Complications were 4 nephrectomies (T: n = 1, R: n = 3), 2 revisions for hemorrhage (R: n = 2), 4 pneumothorax (R: n = 4), and 2 urinary fistulas (T: n = 2). The positive surgical margin rate was comparable between groups (T: n = 3, R: n = 5). CONCLUSIONS Transperitoneal laparoscopic and retroperitoneoscopic partial nephrectomy provide comparable surgical and functional results. One advantage of the retroperitoneoscopic access seems to be a shorter total surgical time.

Abstract
Robot-assisted laparoscopic radical prostatectomy has become a frequently used alternative treatment option in the management of prostate cancer. As more operations are performed, more challenging patient conditions are encountered, for example those with previous abdominal cancer surgery. We present our experience of robot-assisted laparoscopic radical prostatectomy (RALP) in patients with previous cancer surgery. Seven patients with a history of previous surgery for malignancy underwent RALP. All the prostatectomies were performed using the da Vinci™ S surgical system by a single surgeon. All operations were approached transperitoneally. We reviewed perioperative data and surgical outcomes retrospectively. The mean age at surgery was 68.43 years (range 63-82). The mean operative time was 214 ± 47.32 min, and the median estimated blood loss was 500 ml (range 200-1,300). The mean hospital stay was 6.57 ± 2.15 days, and the mean duration of catheterization was 8.29 ± 3.09 days. Nerve-sparing procedure and pelvic lymph node dissection were performed in six patients. Rectal injury occurred in one patient who had undergone hemi-colectomy 15 years previously and was resolved by primary closure. Positive surgical margin was found in three patients. Although one patient had an intraoperative rectal injury, RALP in a patient with previous cancer surgery seems to be feasible and safe in experienced hands.

Abstract
The concept of organ- and function-preserving surgery without compromising the primary goal of complete tumour removal has been recently applied in adrenal surgery. This has been accomplished by open surgery in the past. With recent advancements in minimally invasive surgery, partial adrenalectomy by laparoscopic approach has become feasible. The indications, contraindications and worldwide experience have been reviewed for this article.

Abstract
PURPOSE Open ileal pouch surgery leads to high rates of adhesive small-bowel obstruction (SBO). A laparoscopic approach may reduce these complications. We aimed to review the incidence of adhesive SBO-related complications after open pouch surgery and to model the potential financial impact of a laparoscopic approach purely as an adhesion prevention strategy. MATERIALS AND METHODS We reviewed cases of open ileal pouch patients kept on a database and examined annually. Case notes were studied for episodes of adhesive SBO requiring admission or reoperation. Similar parameters were studied in a small series undergoing laparoscopic pouch surgery. The financial burden of the open access complications was estimated and potential financial impact of a laparoscopic approach modeled. RESULTS Two hundred seventy-six patients were followed up after open surgery (median, 6.3; range, 0.2-20.1 years). There were 76 (28%) readmissions (median length of stay, 7.4 days) in 53 patients (19%) and 28 (10%) reoperations (43% within 1 year). Laparoscopic patients required less adhesiolysis at second-stage surgery (0% vs 36%, p < 0.0001) and had less SBO episodes within 12 months of surgery (0% vs 14%, p < 0.0001) than open patients. Modeling a laparoscopic approach cost $1,450 and saved $3,282, thus netting $1,832 per pouch constructed. CONCLUSION Open ileal pouch surgery results in significant cumulative long-term access-related complications, particularly adhesions. These impose a large medical burden on patients and financial burden on health-care systems, all of which may be recouped by a laparoscopic approach, despite higher theater costs.

Abstract
BACKGROUND This study aimed to evaluate a two-center experience with pediatric transperitoneal laparoscopic nephrectomy, specifically focusing on the outcome parameters of operative time, complication, analgesic requirement, and postoperative stay. METHODS This ambispective study was conducted over a 4-year period between May 2001 and May 2005 in two tertiary pediatric surgical centers. Data were prospectively recorded from an in-house expanded medical audit system (EMAS) and a Microsoft Excel database. Information on patient demographics, operative time, complications, analgesic requirement, and length of hospital stay were retrieved and analyzed. RESULTS A total of 30 consecutive patients with a mean age of 4.43 years (range, 3 months to 15 years) underwent laparoscopic nephrectomy. All the patients underwent unilateral nephrectomy/nephroureterectomy for multidysplastic kidney (n = 12), reflux nephropathy (n = 13), pelvicoureteric junction obstruction (n = 4), or cystic disease of indeterminate cause (n = 1). The mean operative time was 93 +/- 30 min. The principal hemostatic devices used were the Harmonic Scalpel (20 cases), liga clips (5 cases), and hook diathermy and endoshears exclusively (4 cases). There were no conversions, but the intraoperative complications of bleeding (n = 2), difficult location (n = 1), difficult extraction (n = 1), and requirement for a liver retractor (n = 2) were encountered. An additional five patients had problems in the immediate postoperative period, two of whom went on to have long term difficulties with recurrent urinary tract infections resulting from a residual ureteric stump, which required surgery. Nearly one-third of the patients required morphine for analgesia in the immediate postoperative period, with the figure falling to 20% by day 1. The median postoperative hospital stay was 1 day (range, 0-16 days). At this writing, all the patients remain under surveillance with a mean follow-up period of 2.88 years, and no patients have experienced complications secondary to intraabdominal adhesions. CONCLUSION Transperitoneal laparoscopic nephrectomy is technically feasible in most cases of benign renal disease. The intraoperative complications are minimal, and recovery for most is robust. Two-thirds of the patients are discharged within 24 h. In this study, narcotic analgesics were prescribed in about a one-third of all the cases for a limited period. Further problems may be seen when refluxing ureters are incompletely excised. However, the transperitoneal approach does not mitigate against complete excision because the exposure to the pelvis is adequate. At the midterm follow-up assessment, adhesive obstruction was not encountered, confirming this approach as a tenable alternative to other laparoscopic approaches for nephrectomy.

Abstract
BACKGROUND This randomized study aimed to compare the reaction of the immune system to the process of postoperative adhesion formation after open and laparoscopic cholecystectomy. METHODS In this study, 20 mongrel dogs were used: 10 each in the laparoscopic and open cholecystectomy groups. Blood and peritoneal lavage samples were taken up to postoperative day 14, followed by second-look laparoscopy and reoperation to detect the rate of adhesion formation. Also, specimens were obtained from the liver bed for histology. RESULTS In the open cholecystectomy group, the white blood cell count was higher in blood samples and lower in lavage specimens. Adhesion formation was extensive, and the histologic immune reaction was more intensive in the open cholecystectomy group. CONCLUSION This randomized study proved that laparoscopic cholecystectomy was associated with less immune suppression, less inflammatory reaction, and therefore less adhesion formation than open cholecystectomy.

Abstract
PURPOSE Polyethylene glycol (PEG) based hydrogel is available as a tissue sealant and hemostatic aid. We determined the long-term safety and efficacy of its use as a tissue sealant for laparoscopic partial nephrectomy in a porcine model. MATERIALS AND METHODS A total of 16 swine were cycled to 1 control group and 3 treatment groups, which underwent laparoscopic partial nephrectomy with hemostasis achieved only with application of a biodegradable PEG based hydrogel. The 3 treatment groups were sacrificed at 2, 6 and 12 weeks, respectively. Humoral immune response to the hydrogel used in the porcine abdomen was examined using enzyme-linked immunosorbent assay to detect antibodies in the serum at 0, 2, 6 and 12 weeks. Cell mediated immune response was examined using a lymphocyte proliferation assay to measure the response of leukocytes to various mitogens and antigens, including the polymerized hydrogel, at the same intervals. RESULTS Hemostasis was satisfactory after hydrogel application. No adverse effects in the immediate and delayed periods were noted. At 2, 6 and 12 weeks there were no significant differences in hemoglobin or creatinine levels, or in the humoral immune response by enzyme-linked immunosorbent assay. There was no significant difference between test and control pig reactivity to hydrogel as an antigen in the lymphocyte proliferation assay at any time point. Histologically by 6 weeks the animals had almost absorbed the hydrogel with acute inflammation and foreign body reaction resolving by 6 to 12 weeks. No deleterious effect to renal tubules was seen. CONCLUSIONS Biodegradable PEG based hydrogel is effective for long-term use as an agent for hemostasis. There was no detectable humoral immune response and no cell mediated immune response to sealant after 2 weeks. This represents promising sealant technology and it should be further investigated for human use.

Abstract
OBJECTIVE To report our experience with Laparoscopic Partial Adrenalectomy (LPA) for recurrent tumours in patients with hereditary phaeochromocytoma. PATIENTS AND METHODS Five patients with hereditary phaeochromocytoma (4 with von Hippel-Lindau disease and 1 with Multiple Endocrine Neoplasia 2B), who had undergone adrenal surgery previously, presented with recurrent adrenal tumours. One patient was pregnant at 20 weeks of gestation. All patients underwent hormonal evaluation, genetic screening and imaging with CT or MRI, metaiodobenzylguanidine (MIBG) scintigraphy. RESULTS Of the 7 attempted LPA in five patients, five procedures (71%) were successfully completed and total adrenalectomy was needed on two occasions. The adrenal vein could be spared in all patients except one. There were no intra-operative complications. The adrenal function was adequate in all patients without need for steroid supplementation except one patient who lost both adrenals eventually. There was no correlation between the preservation of adrenal vein and adrenocortical function. CONCLUSION Laparoscopic partial adrenalectomy is feasible, safe and effective in recurrent phaeochromocytoma, despite previous adrenal surgery and is technically easier if the previous approach had been laparoscopic as well. Patients with hereditary phaeochromocytoma are prone for recurrent tumours and may need repeated surgical procedures. Hence, minimally invasive approach is ideal for these patients.

Abstract
OBJECTIVES To assess the impact of previous surgery on endoscopic extraperitoneal radical prostatectomy (EERPE). METHODS A total of 500 patients who underwent EERPE for clinically localized prostate cancer between December 2001 and April 2004 were stratified into five groups: group 1, no previous abdominal, inguinal, or prostate surgery; group 2, previous upper abdominal surgery; group 3a, previous lower abdominal or pelvic surgery or open inguinal hernioplasty; group 3b, laparoscopic or endoscopic inguinal hernioplasty; group 4, previous prostate surgery; and group 5, a combination of groups 2, 3, and/or 4. Groups 1 and 2 were analyzed together, because the previous operative fields in group 2 were distant from the space of Retzius. The operative times, complications, and reinterventions were analyzed with the Mann-Whitney U test, chi-square test, and Fisher exact test. RESULTS Of the 500 patients, 335 (67%) and 165 (33%) were in groups 1 and 2 and groups 3 to 5, respectively. The mean overall operative time was 149 +/- 30 minutes. Four patients (0.8%) required transfusions, with no conversion to open surgery and no mortality. A total of 90 complications (18%) and nine reinterventions (1.8%) occurred. EERPE was subjectively more demanding and challenging in patients with previous minimally invasive hernioplasty with mesh placement. No statistical significance was detected between the no=surgery (groups 1 and 2) and previous surgery (groups 3 to 5) patients in terms of overall operative time, positive surgical margin status, complications, or reinterventions. CONCLUSIONS Endoscopic extraperitoneal radical prostatectomy is feasible in patients with various previous abdominal surgical procedures. Previous surgery did not seem to affect the overall operative time or complication or reintervention rate. Previous minimally invasive hernia repair with mesh placement made EERPE more demanding but was not a contraindication.

Abstract
During the last decade laparoscopy has become the standard technique in the urologist's armamentarium due to constant technological advancements and refinements. Laparoscopic radical prostatectomy (LRPE), although technically demanding and associated with a considerable learning curve, has become the operative procedure of choice for patients with clinically localized prostate cancer in selected and specialized urologic centers around the globe. However, a major drawback of LRPE is the transperitoneal route of access to the extraperitoneal organ of the prostate. The principal disadvantages of LRPE are potential intraperitoneal complications. Endoscopic extraperitoneal radical prostatectomy (EERPE) is a further advancement of minimally invasive surgery as it overcomes the limitations of LRPE by the strictly extraperitoneal route of access. Based on our growing experience with this procedure we introduce several technical modifications, improvements, and refinements including a nerve-sparing, potency-preserving approach (nEERPE) in an effort to further improve this minimally invasive procedure. We report our short-term follow-up results after 300 procedures. The mean operative times were 115 min without and 150 min with lymph node dissection, in total 140 min (range: 60-260 min). There was no conversion and the transfusion rate was 1.3%. There were three early reinterventions (two bleeding and one hematoma) and five late reinterventions (four symptomatic lymphoceles and one colostomy due to a rectal fistula). Pathological stage was pT2a in 54 patients (18%), pT2b in 87 patients (29%), pT3a in 115 patients (38.3%), pT3b in 40 patients (13.3%), and pT4 in 4 patients (1.3%). Positive surgical margins were found in 9.2% (13/141) of patients with pT2 tumor and 30.3% (47/155) of patients with pT3 tumor. The mean catheterization time was 6.9 days. Six and twelve months postoperatively 86.3 and 89.6% of the patients were completely continent; 9.2% of patients needed 1-2 pads per day and 4.5 and 1.2% of patients needed more than 2 pads per day, respectively. Short-term oncological and functional results of EERPE are at least as favorable as in LRPE while operative times are shorter and complication rates are low. EERPE is a technical advancement because it combines the advantages of a totally extraperitoneal access with the advantages of a minimally invasive procedure.

Abstract
We describe a case of a boy with Von Hippel-Lindau disease who presented with recurrent right adrenal pheochromocytoma 4.5 years after laparoscopic bilateral partial adrenalectomy. The boy had a second laparoscopic adrenal-sparing removal of the tumor. By this technique, not only the recurrent tumor was successfully removed but also the unaffected adrenal cortex could be preserved for the second time. To our knowledge, this is the first published case of its type.

Abstract
Laparoscopic surgery was originally developed by gynecologists and general surgeons. Based on their experience, the first successful laparoscopic procedures in urology were performed transperitoneally. However, this novel technique transformed traditionally retroperitoneal procedures into transperitoneal procedures, giving free rein to distinct intraperitoneal complications. Retroperitoneal laparoscopy was a later development in urology. This approach has gained increasing popularity throughout the years and has challenged the transperitoneal laparoscopic route in many aspects. This review focuses on the advantages of retroperitoneal laparoscopic surgery of the upper urinary tract.

Abstract
Laparoscopic radical prostatectomy (LRPE) became the operative procedure of choice for patients with clinically localized prostate cancer in selected urologic centers around the world. Principal advantages are the minimal invasive nature of the procedure, a superior visualization of the operative field because of the magnification of the optical system, an exact and watertight anastomosis, the possibility of early catheter removal, and a potentially reduced amount of blood loss. Recent data show that oncologic outcome is not compromised by the minimal invasive nature of the procedure. However, a major drawback of LRPE is the transperitoneal route of access to the extraperitoneal organ of the prostate. Therefore, principal disadvantages of LRPE are potential intraperitoneal complications. Endoscopic extraperitoneal radical prostatectomy is a further advancement of minimal invasive surgery because it overcomes the limitations of LRPE by the strictly extraperitoneal route of access, combining the advantages of minimal invasive surgery with the advantages of an extraperitoneal procedure. This article reviews the literature on minimally invasive (laparoscopic and endoscopic-extraperitoneal) radical prostatectomy.

Abstract
The aim of this paper was to assess long-term results of transperitoneal laparoscopic fenestration in the treatment of symptomatic simple renal cysts. Fifteen consecutive patients (7 men, 8 women), with a mean age of 51 years (range, 36-79 years), underwent transperitoneal fenestration of simple renal cysts (SRC) at our institution from 1994 to 2001. Data were collected by reviewing patients' clinical files, conducting telephone interviews regarding symptoms, and followup renal ultrasonography (US). There were 15 symptomatic cysts (10 parenchymal, 5 peripelvic) ranging in diameter from 3.5 to 20 cm (mean, 8 cm). All patients had lumbar pain and in four (26.6%) the collecting system was compressed by the cysts. Fenestration was carried out laparoscopically in all patients. There was no mortality and no postoperative complications were recorded. No malignancies were detected at final histopathology. Mean length of stay was 2.5 days. All patients were available for long-term followup. At a mean of 60 months (range, 22-93 months) from surgery, three patients (20%) complained of slight discomfort in the lumbar area not requiring any analgesic. No recurrence of the cysts was seen on US. Two asymptomatic patients (13.3%) developed additional cysts originating from sites different than the one operated on. Laparoscopic fenestration of SRC is safe and effective in the long term to relieve patients from symptoms.

Abstract
During the last decade laparoscopy has become a standard technique available to the urologist, through constant technological advances and refinements. The progress of laparoscopic/endoscopic techniques allows the indications for this surgery to include complex oncological procedures like radical prostatectomy. Since the first description of laparoscopic radical prostatectomy (LRP) in the early 1990s the technique has undergone significant technical modifications. Transperitoneal LRP is now a standard procedure and can be used successfully and reproducibly, giving results comparable with those from the open retropubic procedure. Despite many advantages, transperitoneal laparoscopy is associated with potential intraperitoneal complications. Because of the limitations inherent in the transperitoneal route, a totally extraperitoneal endoscopic radical prostatectomy (EERPE) has been developed. The totally extraperitoneal endoscopic access provides a safe and minimally invasive approach to various urological procedures, including prostatectomy. This technical improvement completely obviates intra-abdominal complications. EERPE combines the advantages of minimally invasive laparoscopy and the open retropubic approach. We review the surgical techniques of LRP and EERPE, and highlight the indications, contraindications and outcomes.

Abstract
PURPOSE We evaluated the effect of previous abdominal surgery on perioperative outcomes in patients undergoing a renal/adrenal laparoscopic procedure via a transperitoneal approach. MATERIALS AND METHODS Renal/adrenal laparoscopic procedures via a transperitoneal approach were assessed. Medical records were reviewed to obtain operative and perioperative data. RESULTS Of the 190 patients 76 (40%) had previously undergone abdominal surgery. Patients with versus without an earlier abdominal operation had a longer mean hospital stay (3.8 versus 2.6 days, p = 0.002) but not longer median operative room time (median 220 versus 210 minutes, p >0.05). Operative and major complication rates were greater in patients with previous operations (16% versus 4%, p = 0.009 and 16% versus 5%, p = 0.022, respectively). Access and total complication rates were not altered (4% versus 2% and 33% versus 24%, respectively, p >0.1). An upper midline scar/ipsilateral upper quadrant scar was associated with a greater access complication rate (12% versus 0%, p = 0.029) but not a higher operative complication rate (21% versus 13%, p = 0.502). Multiple logistic regression confirmed that previous abdominal surgery was the only factor associated with operative complications. CONCLUSIONS Previous open abdominal operation increased the risk of operative and major complications, which most likely resulted in increased length of stay. The location of the scar impacted the access complication rate. Patients who have undergone previous open surgical procedures should be counseled on the greater risk of complications if the transperitoneal route is elected. Alternatively a retroperitoneal approach may be used.
