Introduction. Partial nephrectomy represent the standard of care for small renal tumor. Laproscopic approach tends to replace open surgery due to similar oncologic results, but with better eastethic outcomes and earlier socio-professional reintegration. Material and methods. Between January 2010 and February 2017, 55 patients (p) underwent partial nephrectomy at our center for clinically localized renal tumor, 21p with LPN by retroperitoneal approach and 34p with OPN. All patients had a normal contralateral kidney. The selection of patients for nephron-sparing surgery was based on preoperative CT scan, location of the tumor, the individual general health status of the patient and individual surgeon preferences. Results. The mean age of patients with partial nephrectomy was 59.6±16.4 years, with 57.9±11.6 years for laparoscopic subgroup and 61.3±12.4 for open surgery. The transfusion rate was 9.52% in LPN group, while in the OPN there was no need for transfusion. The warm ischemia time was higher in the LPN group (21.8±7.2 min) than OPN group (15.7±2.9). The postoperative complication rate is comparable between LPN and OPN (23.81% v.s. 20.58%), but the LPN had higher intraoperative complications. Conclusion. Laparoscopic partial nephrectomy for renal tumors is superior to open surgery by early mobilization of the patient, the low rate of wound complications, short duration of hospitalization, fast socio-professional reintegration of patient, despite the perioperative complication rate that is higher but of low ClavienDindo grade.

Oncological Outcomes

ObjectivesWe aimed to report the latest and largest pooled analysis and evidence update to compare the perioperative, renal functional, and oncological outcomes between off-clamp and on-clamp robot-assisted partial nephrectomy (RAPN) for renal tumors.Patients and methodsWe performed a systematic literature search using PubMed, Embase, and Web of Science up to August 2021 for studies that compared the efficacy and/or safety between off-clamp and on-clamp RAPN for renal tumors. Outcomes measured were operating time, estimated blood loss (EBL), conversion rate, length of stay (LOS), complication rate, transfusion rate, long-term % decrease in estimated glomerular filtration rate (eGFR), positive surgical margin rate, and recurrence rate.ResultsA total of 21 eligible articles involving 4,493 patients (1,274 off-clamp versus 3,219 on-clamp) were included for the evidence synthesis. Baseline characteristics of the two groups were similar in all outcomes except that lower R.E.N.A.L. score and smaller tumor size were observed in the off-clamp group. Pooled analysis showed shorter operative time, higher EBL, and lower complication rate in the off-clamp group. No significant difference was observed in the conversion rate, LOS, and transfusion rate. The recurrence rates were similar in the two groups, while a lower positive surgical margin rate was observed in the off-clamp group. Finally, the off-clamp group had a superior postoperative renal functional outcome.ConclusionsGiven the presence of heterogeneity and potential bias, urologists should select the clamp strategy based on their experience and patient-specific factors.

Perinephric Fat

Abstract Background Adherent perinephric fat (APF), characterized by inflammatory fat surrounding the kidney, can limit the isolation of renal tumors and increase the operative difficulty in laparoscopic partial nephrectomy (LPN). The aim of this study was to investigate the predictors of APF and its impact on perioperative outcomes during LPN. Methods A total of 215 consecutive patients undergoing LPN for renal cell carcinoma (RCC) from January 2017 to June 2019 at our institute were included. We divided these patients into two groups according to the presence of APF. Radiographic data were retrospectively collected from preoperative cross-sectional imaging. The perioperative clinical parameters were compared between the two groups. Univariate and multivariate analyses were performed to evaluate the predictive factors of APF. Results APF was identified in 41 patients (19.1%) at the time of LPN. Univariate analysis demonstrated that APF was significantly correlated with the male gender (P = 0.001), higher body mass index (P = 0.002), lower preoperative estimated glomerular filtration rate (P = 0.004), greater posterior perinephric fat thickness (P< 0.001), greater perinephric stranding (P< 0.001), and higher Mayo Adhesive Probability (MAP) score (P< 0.001). The MAP score (P< 0.001) was the only variable that remained an independent predictor for APF in multivariate analysis. We found that patients with APF had longer operative times (P< 0.001), warm ischemia times (P = 0.001), and greater estimated blood loss (P = 0.003) than those without APF. However, there were no significant differences in surgical approach, transfusion rate, length of postoperative stay, complication rate, or surgical margin between the two groups. Conclusions Several specific clinical and radiographic factors including the MAP score can predict APF. The presence of APF is associated with an increased operative time, warm ischemia time, and greater estimated blood loss but has no impact on other perioperative outcomes in LPN.

The Impact

Objectives: While the choice of surgical approach for laparoscopic nephrectomy is broadly split between transperitoneal and retroperitoneal options, the evidence for the impact of this decision on perioperative outcomes is built on relatively small volume data, with often inconsistent findings and conclusions. We aimed to assess the impact of operative approach on perioperative outcomes for laparoscopic radical, partial and simple nephrectomy and nephroureterectomy through analysis of the British Association of Urological Surgeons (BAUS) Nephrectomy database. Patients and methods: All patients added to the BAUS Nephrectomy database with laparoscopic surgery between 2012 and 2017 inclusively were included and subdivided by operation and surgical approach. Preoperative patient and tumour characteristics, as well as intraoperative and post-operative short-term outcomes, were assessed. Results: Overall, 26,682 operations were documented over the review window (81.6% transperitoneal). Small increases in blood loss ( p = 0.001), transfusion rate ( p = 0.02) and operative length ( p = 0.01) were seen for transperitoneal radical nephrectomies and longer hospital stays seen for retroperitoneal procedures (radical nephrectomy p = 0.00l; partial nephrectomy p = 0.04). Retroperitoneal procedures were associated with increased rates of conversion for simple nephrectomy ( p = 0.02), nephroureterectomy ( p = 0.03) and most notably partial nephrectomy (10.5% versus 4.4%; p = 0.001). No further variation in intraoperative complications, post-operative complications, tumour margin positivity rates, unintended ITU admission, or likelihood of death was identified related to surgical approach. Conclusion: Observed variations in perioperative outcomes were generally modest in nature, and little ground is seen to support a change in operative technique for those committed to one approach. A caveat to this exists with open conversion for retroperitoneal partial nephrectomies and requires careful consideration of patient selection by the individual surgeon. Level of evidence: 4

Abstract Background To compare the perioperative outcomes of robotic partial nephrectomy (RPN) versus laparoscopic partial nephrectomy (LPN) for complex renal tumors with a RENAL nephrometry score≥7. Methods We searched PubMed, EMBASE and the Cochrane Central Register for studies from 2000 to 2020 to evaluate the perioperative outcomes of RPN and LPN in patients with a RENAL nephrometry score≥7. We used RevMan 5.2 to pool the data. Results Seven studies were acquired in our study. No significant differences were found in the estimated blood loss (WMD: 34.49; 95% CI: -75.16-144.14; p=0.54), hospital stay (WMD: -0.59; 95% CI: -1.24–0.06; p=0.07), positive surgical margin (OR: 0.85; 95% CI: 0.65–1.11; p =0.23), major postoperative complications(OR: 0.90; 95% CI: 0.52–1.54; p=0.69) and transfusion (OR: 0.72; 95% CI: 0.48–1.08; p =0.11) between the groups. RPN showed better outcomes in the operating time (WMD: -22.45; 95% CI: -35.06 to -9.85; p=0.0005), postoperative renal function (WMD: 3.32; 95% CI: 0.73–5.91; p=0.01), warm ischemia time (WMD: -6.96; 95% CI: -7.30–-6.62; p <0.0001), conversion rate to radical nephrectomy (OR: 0.34; 95% CI: 0.17 to 0.66; p=0.002) and intraoperative complications (OR: 0.52; 95% CI: 0.28–0.97; p=0.04).Conclusions RPN showed better perioperative clinical outcomes than LPN for the treatment of complex renal tumors with a RENAL nephrometry score≥7.

Background Comparable oncological outcomes have been seen after surgical nephrectomy and thermal ablation of renal tumors recently. However, periprocedural outcome needs to be assessed for aiding treatment decision. Purpose To compare efficacy rates and periprocedural outcome (technical success, session time, hospitalization time, and complications) after renal tumor treatment with laparoscopic partial nephrectomy (LPN) or radiofrequency ablation (RFA). Material and Methods The initial experience with 49 (treated with LPN) and 84 (treated with RFA) consecutive patients for a single renal tumor (diameter ≤ 5 cm, limited to the kidney) during 2007–2014 was evaluated. Patient and tumor characteristics, efficacy rates, and periprocedural outcome were collected retrospectively. The stratified Mantel Haenzel and Van Elteren tests, adjusted for tumor complexity (with the modified R.E.N.A.L nephrometry score [m-RNS]), were used to assess differences in treatment outcomes. Results Primary efficacy rate was 98% for LPN and 85.7% for RFA; secondary efficacy rate was 93.9% for LPN and 95.2% for RFA; and technical success rate was 87.8% for LPN and 100% for RFA. Median session (m-RNS adjusted P < 0.001; LPN 215 min, RFA 137 min) and median hospitalization time were longer after LPN (m-RNS adjusted P < 0.001; LPN 5 days, RFA 2 days). Side effects were uncommon (LPN 2%, RFA 4.8%). Complications were more frequent after LPN (m-RNS adjusted P < 0.001; LPN 42.9%, RFA 10.7%). Conclusion Both methods achieved equivalent secondary efficacy rates. RFA included several treatment sessions, but session and hospitalization times were shorter, and complications were less frequent than for LPN. The differences remained after adjustment for renal tumor complexity.

Abstract Open partial nephrectomy, or nephron-sparing surgery (NSS), is now considered as the standard for small renal tumors treatment. The oncologic efficacy and safety of NSS for the treatment of stage-T1a renal tumors have been repeatedly demonstrated to be equivalent to radical nephrectomy. A 66-year-old gentleman chronic smoker was incidentally found to have a small mid pole lesion in the left kidney on routine ultrasound scan, CT finding was 2x2 cm mid pole tumor, no involvement or metastasis, the patient given the option of partial nephrectomy. In surgery, the left kidney was explored, and the tumor mass was seen to occupy the mid pole. The mid pole branch of the renal artery was clamped after cooling the kidney with ice slush following 300cc of 20% mannitol infusion. In-situ nephron-sparing left nephrectomy was done with a margin of 1cm minor upper calyceal injury repaired. The patient was discharged five days postoperative. Gross examination of the specimen revealed a wedge biopsy of the mid pole with attached perinephric fat with swelling part at the outer surface, pushing the capsule. Microscopic sections show a well-defined tumor mass in the renal parenchyma, surrounded by a fibrous capsule, composed of a multilocular cystic area lined by malignant cells. NSS initially was reserved for patients with solitary kidneys, tumors, and those with significant comorbidities predisposing to future renal failure; indications have expanded recently to allow elective partial nephrectomy in the setting of a normal contralateral kidney.

Partial nephrectomy (PN) is currently the standard treatment for T1 renal tumors. Minimally invasive PN offers decreased blood loss, shorter length of stay, rapid convalescence, and improved cosmesis. Due to the challenges inherent in laparoscopic partial nephrectomy, its dissemination has been stifled. Robot-assisted partial nephrectomy (RAPN) offers an intuitive platform to perform minimally invasive PN. It is one of the fastest growing robotic procedures among all surgical subspecialties. RAPN continues to improve upon the oncological and functional outcomes of renal tumor extirpative therapy. Herein, we describe the surgical technique, outcomes, and complications of RAPN.
