On-Clamp vs. Off-Clamp Robot-Assisted Partial Nephrectomy for cT2 Renal Tumors: Retrospective Propensity-Score-Matched Multicenter Outcome Analysis. Cancers (Basel) 2022; 14:cancers14184431. [PMID: 36139591 PMCID: PMC9496892 DOI: 10.3390/cancers14184431] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 08/30/2022] [Accepted: 09/03/2022] [Indexed: 11/16/2022] Open
Abstract
We compared perioperative outcomes after on-clamp versus off-clamp robot-assisted partial nephrectomy (RAPN) for >7 cm renal masses. A multicenter dataset was queried for patients who had undergone RAPN for a cT2cN0cM0 kidney tumor from July 2007 to February 2022. The Trifecta achievement (negative surgical margins, no severe complications, and ≤ 30% postoperative estimated glomerular filtration rate (eGFR) reduction) was considered a surrogate of surgical quality. Overall, 316 cases were included in the analysis, and 58% achieved the Trifecta. A propensity-score-matched analysis generated two cohorts of 89 patients homogeneous for age, ASA score, preoperative eGFR, and RENAL score (all p > 0.21). Compared to the on-clamp approach, OT was significantly shorter in the off-clamp group (80 vs. 190 min; p < 0.001), the incidence of sRFD was lower (22% vs. 40%; p = 0.01), and the Trifecta rate higher (66% vs. 46%; p = 0.01). In a crude analysis, >20 min of hilar clamping was associated with a significantly higher risk of sRFD (OR: 2.30; 95%CI: 1.13−4.64; p = 0.02) and with reduced probabilities of achieving the Trifecta (OR: 0.46; 95%CI: 0.27−0.79; p = 0.004). Purely off-clamp RAPN seems to be a safe and viable option to treat cT2 renal masses and may outperform the on-clamp approach regarding perioperative surgical outcomes.

Abstract
IMPORTANCE Planning complex operations such as robotic-assisted partial nephrectomy requires surgeons to review 2-dimensional computed tomography or magnetic resonance images to understand 3-dimensional (3-D), patient-specific anatomy. OBJECTIVE To determine surgical outcomes for robotic-assisted partial nephrectomy when surgeons reviewed 3-D virtual reality (VR) models during operative planning. DESIGN, SETTING, AND PARTICIPANTS A single-blind randomized clinical trial was performed. Ninety-two patients undergoing robotic-assisted partial nephrectomy performed by 1 of 11 surgeons at 6 large teaching hospitals were prospectively enrolled and randomized. Enrollment and data collection occurred from October 2017 through December 2018, and data analysis was performed from December 2018 through March 2019. INTERVENTIONS Patients were assigned to either a control group undergoing usual preoperative planning with computed tomography and/or magnetic resonance imaging only or an intervention group where imaging was supplemented with a 3-D VR model. This model was viewed on the surgeon's smartphone in regular 3-D format and in VR using a VR headset. MAIN OUTCOMES AND MEASURES The primary outcome measure was operative time. It was hypothesized that the operations performed using the 3-D VR models would have shorter operative time than those performed without the models. Secondary outcomes included clamp time, estimated blood loss, and length of hospital stay. RESULTS Ninety-two patients (58 men [63%]) with a mean (SD) age of 60.9 (11.6) years were analyzed. The analysis included 48 patients randomized to the control group and 44 randomized to the intervention group. When controlling for case complexity and other covariates, patients whose surgical planning involved 3-D VR models showed differences in operative time (odds ratio [OR], 1.00; 95% CI, 0.37-2.70; estimated OR, 2.47), estimated blood loss (OR, 1.98; 95% CI, 1.04-3.78; estimated OR, 4.56), clamp time (OR, 1.60; 95% CI, 0.79-3.23; estimated OR, 11.22), and length of hospital stay (OR, 2.86; 95% CI, 1.59-5.14; estimated OR, 5.43). Estimated ORs were calculated using the parameter estimates from the generalized estimating equation model. Referent group values for each covariate and the corresponding nephrometry score were summed across the covariates and nephrometry score, and the sum was exponentiated to obtain the OR. A mean of the estimated OR weighted by sample size for each nephrometry score strata was then calculated. CONCLUSIONS AND RELEVANCE This large, randomized clinical trial demonstrated that patients whose surgical planning involved 3-D VR models had reduced operative time, estimated blood loss, clamp time, and length of hospital stay. TRIAL REGISTRATION ClinicalTrials.gov identifiers (1 registration per site): NCT03334344, NCT03421418, NCT03534206, NCT03542565, NCT03556943, and NCT03666104.

Abstract
OBJECTIVES To compare the outcomes of retroperitoneal vs transperitoneal approach for robot-assisted partial nephrectomy (RAPN). MATERIALS AND METHODS A systematic review of the literature was performed through January 2018 using PubMed, Scopus, and Ovid databases. Article selection proceeded according to the search strategy based on PRISMA criteria. Only studies comparing retroperitoneal to transperitoneal approach for RAPN were deemed eligible for inclusion. RESULTS Seven retrospective case-control studies were identified and included in the analysis, with a total number of 1379 patients (866 for transperitoneal group; 513 for retroperitoneal group). In the retroperitoneal group, tumors were slightly larger [weighted mean difference (WMD): 0.29 cm; 95% confidence interval (CI): 0.04-0.54; p = 0.02], and more frequently located posterior/lateral (odds ratio: 0.61; 95% CI: 0.41-0.90; p = 0.01). In two of the studies only posterior tumors had been included. Both operating time (WMD 20.17 min; 95% CI 6.46-33.88; p = 0.004) and estimated blood loss (WMD 54.57 mL; 95% CI 6.73-102.4; p = 0.03) were significantly lower in the retroperitoneal group. In addition, length of stay was significantly shorter in the retroperitoneal group (WMD 0.46 days; CI 95% 0.15-0.76; p = 0.003). No differences were found regarding overall (p = 0.67) and major (p = 0.82) postoperative complications, warm ischemia time (p = 0.96), and positive surgical margins (p = 0.95). CONCLUSIONS Retroperitoneal RAPN can offer in select patients similar outcomes to those of the most common transperitoneal RAPN. Furthermore, it may be particularly advantageous for posterior upper pole and perihilar tumors and associated with reduction in operative time and hospital stay. Robotic surgeons should be ideally familiar with both approaches to adapt their surgical strategy to confront renal neoplasms from a position of technical advantage and ultimately optimize outcomes.

Abstract
Zyflamend is a highly controlled blend of 10 herbal extracts that synergistically impact multiple cell signaling pathways with anticancer and anti-inflammatory properties. More recently, its effects were shown to also modify cellular energetics, for example, activation of fatty acid oxidation and inhibition of lipogenesis. However, its general metabolic effects in vivo have yet to be explored. The objective of this study was to characterize the tissue specific metabolomes in response to supplementation of Zyflamend in mice, with a comparison of equivalent metabolomics data generated in plasma from humans supplemented with Zyflamend. Because Zyflamend has been shown to activate AMPK, the "energy sensor" of the cell, in vitro, the effects of Zyflamend on adiposity were also tested in the murine model. C57BL/6 mice were fed diets that mimicked the macro- and micronutrient composition of the U.S. diet with and without Zyflamend supplementation at human equivalent doses. Untargeted metabolomics was performed in liver, skeletal muscle, adipose, and plasma from mice consuming Zyflamend and in plasma from humans supplemented with Zyflamend at an equivalent dose. Adiposity in mice was significantly reduced in the Zyflamend-treated animals (compared with controls) without affecting body weight or weight gain. Based on KEGG pathway enrichment, purine and pyrimidine metabolism (potential regulators of AMPK) were particularly responsive to Zyflamend across all tissues, but only in mice. Consistent with the metabolomics data, Zyflamend activated AMPK and inhibited acetyl CoA-carboxylase in adipose tissue, key regulators of lipogenesis. Zyflamend reduces adipose tissue in mice through a mechanism that likely involves the activation of AMPK.

Abstract
The demand for surgical correction of symptomatic pelvic organ prolapse has significantly increased as the general population has aged. In the modern era, patients with bothersome prolapse desire durable corrective surgery that offers tangible improvement in quality of life and is associated with minimal morbidity. Open abdominal sacral colpopexy (ASC) had long been considered the "gold standard" approach to achieve these reconstructive goals but was construed as being overly invasive with prolonged recovery and unacceptable pain. Transvaginal approaches were favored as a less invasive alternative, but durability and the more recent climate of fear engendered by mesh complications has made many surgeons and patients averse to these procedures. Improved laparoscopic dexterity and experience has led to renewed interest in ASC. Laparoscopic ASC achieves the aforementioned reconstructive goals but with decreased pain and faster recovery inherent to minimally invasive surgery. More recently, the widespread advent and adoption of robotics has made minimally invasive ASC more accessible to surgeons through its enabling technology. This article will review our team's robust experience with laparoscopic and robotic ASC with a focus on our patient evaluation, consent process, and our tips and tricks gained through experience.

Abstract
OBJECTIVES Thyroid-like follicular carcinoma of the kidney continues to confound the practicing pathologist with its close resemblance to the follicular variant of thyroid carcinoma, as well as other benign and malignant entities. Our goal is to expand the knowledge of this rare renal cell carcinoma subtype, which is morphologically similar to follicular carcinoma of the thyroid but lacks expression of characteristic thyroid immunohistochemical markers such as TTF-1 and thyroglobulin. METHODS We evaluated the gross, histologic, immunohistochemical, and fluorescence in situ hybridization (FISH) studies of a new case and performed a comprehensive review of the literature. RESULTS The lesion was spongy and well-circumscribed. Microscopically it showed variably sized follicular structures, filled with abundant, deeply eosinophilic, colloid-like material. At the periphery, it displayed areas resembling metanephric adenoma and early stages of nephrogenesis. The tumor cells strongly expressed CK7, PAX-8, PAX-2, vimentin, EMA, and CK19 immunostains. Other markers, such as CD10, RCC, HBME-1, thyroglobulin, and TTF-1, were not immunoreactive. The tumor was negative for trisomy of both 7 and 17 and showed borderline monosomies (losses) of both chromosomes in FISH studies. CONCLUSIONS Five years of preoperative observation and lack of recurrence bring further insight into the slow progressive nature of this neoplasm and support a low malignant potential. Proper identification is important to secure adequate treatment and follow-up.

Abstract
PURPOSE Gleason 6 (3+3) is the most commonly diagnosed prostate cancer among men with prostate specific antigen screening, the most histologically well differentiated and is associated with the most favorable prognosis. Despite its prevalence, considerable debate exists regarding the genetic features, clinical significance, natural history, metastatic potential and optimal management. MATERIALS AND METHODS Members of the Young Urologic Oncologists in the Society of Urologic Oncology cooperated in a comprehensive search of the peer reviewed English medical literature on Gleason 6 prostate cancer, specifically focusing on the history of the Gleason scoring system, histological features, clinical characteristics, practice patterns and outcomes. RESULTS The Gleason scoring system was devised in the early 1960s, widely adopted by 1987 and revised in 2005 with a more restrictive definition of Gleason 6 disease. There is near consensus that Gleason 6 meets pathological definitions of cancer, but controversy about whether it meets commonly accepted molecular and genetic criteria of cancer. Multiple clinical series suggest that the metastatic potential of contemporary Gleason 6 disease is negligible but not zero. Population based studies in the U.S. suggest that more than 90% of men newly diagnosed with prostate cancer undergo treatment and are exposed to the risk of morbidity for a cancer unlikely to cause symptoms or decrease life expectancy. Efforts have been proposed to minimize the number of men diagnosed with or treated for Gleason 6 prostate cancer. These include modifications to prostate specific antigen based screening strategies such as targeting high risk populations, decreasing the frequency of screening, recommending screening cessation, incorporating remaining life expectancy estimates, using shared decision making and novel biomarkers, and eliminating prostate specific antigen screening entirely. Large nonrandomized and randomized studies have shown that active surveillance is an effective management strategy for men with Gleason 6 disease. Active surveillance dramatically reduces the number of men undergoing treatment without apparent compromise of cancer related outcomes. CONCLUSIONS The definition and clinical relevance of Gleason 6 prostate cancer have changed substantially since its introduction nearly 50 years ago. A high proportion of screen detected cancers are Gleason 6 and the metastatic potential is negligible. Dramatically reducing the diagnosis and treatment of Gleason 6 disease is likely to have a favorable impact on the net benefit of prostate cancer screening.

Abstract
Screening is not universally beneficial due to over- and under-diagnosis, and false positives that beget additional testing and associated adverse events and expense. We examined data from all men who participated in a mass community prostate cancer screening between May 2009 and September 2010. The data contained information regarding patient demographics, family history of prostate cancer, lower urinary tract symptoms, prior history of prostate cancer, most recent digital rectal examination, and the presence of an established relationship with a physician. Current American Urological Association screening recommendations were then applied to determine the appropriateness of our outreach effort. A total of 438 men (mean age 66.5 years) underwent screening. A total of 106 (24.2%) patients in our study met contemporary criteria for screening. Of these men, the vast majority was well educated, well insured, and well informed about the need for prostate cancer screening. Based on these data, mass community-based prostate cancer screening does not appear to identify and screen at-risk men. Future efforts at mass screening should more carefully target men most likely to benefit.

Abstract
INTRODUCTION The aim of this study was to determine the incidence, presentation, management, and outcomes of chylous ascites following laparoscopic donor nephrectomy. METHODS An Internet-based, multi-institutional survey was performed using http://www.surveymonkey.com. An email invitation to the voluntary survey was sent to 30 transplant centers and posted on CenterSpan, an email forum for transplant surgeons. The number of living donor transplantations and the number of cases of chylous ascites with clinical information, treatment and outcomes were sought from the questionnaire. RESULTS A total of 12 centers responded and reported 7683 cases of live donor nephrectomy. The reported incidence of postoperative chylous ascites was 0.013% (n = 12). Six centers reported 10 cases of chylous ascites following laparoscopic donor nephrectomy and 2 cases after open donor nephrectomy. Among the eight patients who developed chylous ascites following laparoscopic donor nephrectomy, presentation was typically 2 weeks after the date of initial surgery. Conservative therapy was successful in 50% of cases. Refractory ascites managed secondarily with surgical intervention had a success rate of 100%. CONCLUSION Chylous ascites is a rare complication following laparoscopic donor nephrectomy. Initial treatment should be conservative, with surgical therapy reserved for refractory cases.

Abstract
The demand for surgical correction of pelvic organ prolapse is expected to grow as the aging population remains active and focused on quality of life. Definitive correction of pelvic organ prolapse can be accomplished through both vaginal and abdominal approaches. This article provides a contemporary reference source that specifically addresses the historical framework, diagnostic algorithm, and therapeutic options for the treatment of female pelvic organ prolapse. Particular emphasis is placed on the role and technique of abdominal-based reconstruction using robotic technology and the evolving controversy regarding the use of synthetic vaginal mesh.

Abstract
The aim of this study was to analyse natural orifice transluminal endoscopic surgery (NOTES)-related publications over the last 5 years. A systematic literature search was done to retrieve publications related to NOTES from 2006 to 2011. The following variables were recorded: year of publication; article type; study design; setting; Journal Citation Reports® journal category; authors area of surgical speciality; geographic area of origin; surgical procedure; NOTES technique; NOTES access route; number of clinical cases. A time-trend analysis was performed by comparing early (2006-2008) and late (2009-2011) study periods. Overall, 644 publications were included in the analysis and most papers were found in general surgery journals (50.9%). Studies were most frequently clinical series (43.9%) and animal experimental (48%), with the articles focusing primarily on cholecystectomy, access creation and closure, and peritoneoscopy. Pure NOTES techniques were performed in most of the published reports (85%) with the remaining cases being hybrid NOTES (7.4%) and NOTES-assisted procedures (6.1%). The access routes included transgastric (52.5%), transcolonic (12.3%), transvesical (12.5%), transvaginal (10.5%), and combined (12.3%). From the early to the late period, there was a significant increase in the number of randomised controlled trials (5.6% vs 7.2%) or non-randomised but comparative studies (5.6% vs 22.9%) (P < 0.001) and there was also a significant increase in the number of colorectal procedures and nephrectomies (P = 0.002). Pure NOTES remained the most studied approach over the years but with increased investigation in the field of NOTES-assisted techniques (P = 0.001). There was also a significant increase in the adoption of transvesical access (7% vs 15.6%) (P = 0.007). NOTES is in a developmental stage and much work is still needed to refine techniques, verify safety and document efficacy. Since the first description of the concept of NOTES, >2000 clinical cases, irrespective of specialty, have been reported. NOTES remains a field of intense clinical and experimental research in various surgical specialities.

Abstract
PURPOSE During pregnancy a ureteral stone and its management may pose risks for the mother and fetus. Definitive ureteroscopic management of an obstructing stone during pregnancy has been increasingly used without a reported increased incidence of urological complications. However, the rate of obstetric complications of ureteroscopy during pregnancy remains undefined. MATERIALS AND METHODS Charts of pregnant women who had undergone ureteroscopy at 5 tertiary centers were reviewed. Patient and procedure characteristics were collected. Records were evaluated for the occurrence of obstetric complications in the postoperative period. RESULTS A total of 46 procedures were performed in 45 patients at 5 institutions. There were 2 obstetric complications (4.3%), including 1 preterm labor managed conservatively and 1 preterm labor resulting in preterm delivery. There was no fetal loss. No statistically significant characteristics were identified differentiating those patients having obstetric complications. CONCLUSIONS Ureteroscopy performed during pregnancy has been previously reported to be urologically safe and effective for addressing ureteral stones. In our multi-institutional series a 4% rate of obstetric complications was observed. Based on this risk a multidisciplinary approach is prudent for the pregnant patient undergoing ureteroscopy.

Abstract
Laparoendoscopic single site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) are emerging platforms to further reduce the invasive profile of surgery. As feasibility of an increasing array of procedures in both platforms is being demonstrated, with out comes comparable to multiport laparoscopy, there has been a parallel proliferation of concepts, terminology and technology. In this article, we describe the rationale behind the evolving paradigm shift towards truly "scarless" surgery and address the terminology associated with these surgical approaches.

Abstract
BACKGROUND Laparoendoscopic single-site surgery (LESS) has gained popularity in urology over the last few years. OBJECTIVE To report a large multi-institutional worldwide series of LESS in urology. DESIGN, SETTING, AND PARTICIPANTS Consecutive cases of LESS done between August 2007 and November 2010 at 18 participating institutions were included in this retrospective analysis. INTERVENTION Each group performed a variety of LESS procedures according to its own protocols, entry criteria, and techniques. MEASUREMENTS Demographic data, main perioperative outcome parameters, and information related to the surgical technique were gathered and analyzed. Conversions to reduced-port laparoscopy, conventional laparoscopy, or open surgery were evaluated, as were intraoperative and postoperative complications. RESULTS AND LIMITATIONS Overall, 1076 patients were included in the analysis. The most common procedures were extirpative or ablative operations in the upper urinary tract. The da Vinci robot was used to operate on 143 patients (13%). A single-port technique was most commonly used and the umbilicus represented the most common access site. Overall, operative time was 160±93 min and estimated blood loss was 148±234 ml. Skin incision length at closure was 3.5±1.5 cm. Mean hospital stay was 3.6±2.7 d with a visual analog pain score at discharge of 1.5±1.4. An additional port was used in 23% of cases. The overall conversion rate was 20.8%; 15.8% of patients were converted to reduced-port laparoscopy, 4% to conventional laparoscopy/robotic surgery, and 1% to open surgery. The intraoperative complication rate was 3.3%. Postoperative complications, mostly low grade, were encountered in 9.5% of cases. CONCLUSIONS This study provides a global view of the evolution of LESS in the field of minimally invasive urologic surgery. A broad range of procedures have been effectively performed, primarily in the academic setting, within diverse health care systems around the world. Since LESS is performed by experienced laparoscopic surgeons, the risk of complications remains low when stringent patient-selection criteria are applied.

Abstract
OBJECTIVES To present the longitudinal outcomes in an observational cohort of patients who had undergone treatment of stress urinary incontinence with a single incision mid-urethral sling (MUS). METHODS A prospective, observational study of all female patients who had undergone surgical intervention with the MiniArc MUS was performed. The surgical candidates underwent history and physical examination and urodynamic testing, as indicated. Quality of life questionnaires (Urogenital Distress Inventory [UDI-6] and Incontinence Impact Questionnaire [IIQ-7]) were administered preoperatively. The salient operative data were recorded. The patients were followed up postoperatively for evidence of treatment success and adverse events. The patients completed the UDI-6, IIQ-7, and Female Sexual Function Index questionnaires at 1 and 12 months after treatment. RESULTS From September 2007 to October 2008, 120 patients underwent placement of the MiniArc MUS for the treatment of stress urinary incontinence. The mean patient age was 58.4 years. The mean body mass index was 27.2 kg/m(2). The mean preoperative daily pad use was 2.4. The mean preoperative IIQ-7 and UDI-6 score was 86.58 and 62.5, respectively. Of the 120 patients, 108 (90%) completed a minimum follow-up period of 12 months. Of these 108 patients, 101 (94%) were cured/dry. The mean postoperative pad use was 0.2 (P < .001). The mean IIQ-7 and UDI-6 score was 13.32 (P < .001) and 12.5 (P < .001), respectively. The Female Sexual Function Index results demonstrated no discomfort with intercourse in 49%, occasional discomfort in 9%, and frequent discomfort in 2%. The remaining 40% of our patients were not sexually active. CONCLUSIONS Our results have shown that the MiniArc MUS offers excellent outcomes that are durable at 1 year after treatment.

Abstract
OBJECTIVES To present comparative outcomes among matched patients who underwent robotic partial nephrectomy (RPN) or laparoscopic partial nephrectomy (LPN) by a single surgeon at a single institution. METHODS Between March 2002 and August 2009, a retrospective review of 261 consecutive patients who underwent LPN (n = 186) or RPN (n = 75) by a single surgeon was performed. Patients were matched for age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) score, and tumor size, side, and location. Perioperative outcomes were compared. RESULTS A matched cohort of 150 patients who underwent RPN (n = 75) or LPN (n = 75) were compared. There was no significant difference between the 2 cohorts with respect to patient age (P = .17), BMI (P = .68), ASA score (P = .96), preoperative estimated glomerulofiltration rate (eGFR; P = .54), or tumor size (P = .17). Mean operative time for RPN was 200 vs 197 minutes for LPN (P = .75). Mean estimated blood loss (EBL) was higher in the RPN cohort (323 vs 222 mL, P = .01). There was no significant difference with respect to warm ischemia time (18.2 minutes vs 20.3 minutes, P = .27), length of hospitalization (P = .84), percent change in eGFR (P = .80), or adverse events (P = .52). All surgical margins were negative. CONCLUSIONS Although initial surgical experience with RPN was included in this study and compared with a vast experience in LPN by the same surgeon, RPN offers at least comparable outcomes to LPN.
