Purpose: The management of solitary kidney tumors is a surgical challenge, requiring irreproachable results on both oncological and functional outcomes. The goal of our study was to compare the perioperative results of robotic-assisted partial nephrectomy (RAPN) to open surgery in this indication., Methods: We led a multicentric study based on the prospectively maintained French national database UroCCR. Patients who underwent partial nephrectomy on a solitary kidney between 1988 and 2020 were included. Clinical and pathological data were retrospectively analyzed. The main outcome of the study was the analysis of the variation of the estimated glomerular filtration rate (eGFR) calculated according to MDRD at 3, 6, 12, and 24 months depending on the chosen surgical approach. The secondary outcomes were the comparison of Trifecta success, perioperative complications, and length of hospital stay., Results: In total, 150 patients were included; 68 (45%) in the RAPN group and 82 (55%) in the open surgery group. The two groups were comparable for all data. The variation of eGFR at 3, 6, 12, or 24 months was comparable without any significant difference between the 2 groups (p = 0.45). Trifecta was achieved in 40% of the patients in the RAPN group and 33% in the open group (p = 0.42). A significant difference was observed for the length of stay, 5 days for the robot group versus 9 days for the open surgery group (p < 0.0001)., Conclusion: In our study, the surgical approach did not modify functional results and we noted a significant decrease in hospital stay and complications in the RAPN group. RAPN is a safe and efficient method for management of kidney tumors in solitary kidneys., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

To describe clinical outcomes of patients aged 75 years and above after partial nephrectomy (PN), and to assess independent factors of postoperative complications. We retrospectively reviewed information from our multi-institutional database. Every patient over 75 years old who underwent a PN between 2003 and 2016 was included. Peri-operative and follow up data were collected. Multivariate logistic regression was performed to determine independent predictive factors of postoperative complications. We reviewed 191 procedures including 69 (40%) open-surgery, and 122 (60%) laparoscopic procedures, of which 105 were robot-assisted. Median follow-up was 25 months. The mean age was 78 [75-88]. The American Society of Anesthesiologist's score was 1, 2, 3 and 4 in 10.5%, 60%, 29% and 0.5% of patients respectively. The mean tumor size was 4.6 cm. Indication of PN was elective in 122 (65%) patients and imperative in 52 patients (28%). The median length of surgery was 150(± 60) minutes, and the median estimated blood loss 200 ml. The mean glomerular filtration rate was 71.5 ml/minute preoperatively, and 62 ml/min three months after surgery. The severe complications (Clavien III-V) rate was 6.2%. On multivariate analysis, the robotic-assisted procedure was an independent protective factor of medical postoperative complications (Odds Ration (OR) = 0.31 [0.12-0.80], p = 0.01). It was adjusted for age and RENAL score, robotic-assisted surgery (OR = 0.22 [0.06-0.79], p = 0.02), and tumor size (OR = 1.13 [1.02-1.26], p = 0.01), but the patients age did not forecast surgical complications. Partial nephrectomy can be performed safely in elderly patients with an acceptable morbidity, and should be considered as a viable treatment option. Robotic assistance is an independent protective factor of postoperative complications., (© 2021. The Author(s).)

Objective: To evaluate oncologic and functional outcomes after percutaneous cryoablation (PCA) for renal masses based on our single center experience., Patients and Methods: We retrospectively identified 26 patients who underwent PCA for 28 tumors between November 2006 and June 2011. Patient's demographics and baseline clinical characteristics, tumor features, perioperative information, and postoperative outcomes we rerecorded. A biopsy was performed systematically before each procedure. Control imaging was obtained at 1, 3, 6 and 12 months, and yearly thereafter. Oncological outcomes were determined by radiographic evidence of tumor recurrence, which was defined by contrast enhancement at the cryoablation site on control imaging at M3., Results: Patients had mean age of 70.1 years, mean Charlson comorbidity index (CCI) and body mass index) were 6 and 29 kg/m(2) respectively. There were 11 kidney transplants, including 4 solitary. Mean tumor size was 29.5mm and was represented mainly by clear cell renal cell carcinomas (16/28), endophytic (17/28) and midkidney (14/28) (±9.8). Twenty-five cryoablations were performed percutaneously by two lumbotomy. Mean clearance preoperative MDRD was 66,1 mL/min. Mean length of stay was 3.3 days (±2.2). Intraoperative complications consisted of 2 pneumothorax and 6 minor complications postoperative (Clavien≤2). There were no major complications. Mean follow-up was 27.5 months (±15.7), MDRD clearance distance was 61.9 mL/min. Overall survival and disease-specific survival was 100%, while the recurrence-free survival was 78.6% (5 recurrences and 1 failure treatment)., Conclusion: The percutaneous cryoablation provides a safe and oncologically to extirpative surgery for renal masses in patients with significant medical comorbidities., Level of Evidence: 5., (Copyright © 2016 Elsevier Masson SAS.

Objectives: To evaluate the consequences of laparoscopic nephrectomy with vaginal extraction on sexual quality of life., Methods: Sixteen patients (mean age: 53.8 years) who underwent laparoscopic nephrectomy with vaginal extraction between September 2010 and February 2014 were included in this monocentric prospective study. All patients underwent a preoperative gynecological examination to evaluate the feasibility of vaginal extraction. The sexual function of the patients was evaluated using the French version of the Female Sexual Function Index (FSFI). The patients completed an initial FSFI preoperatively then another postoperatively after the resumption of sexual activities., Results: The mean hospital stay was 2.2 days (0-5 days). No postoperative complications were observed except for one case of bleeding at the vaginal incision 4 days after surgery, resolved with a single suture under local anesthesia. Fifteen patients (94%) completed both the pre- and postoperative FSFIs. Three patients were sexually inactive and one was a virgin. The pre- and postoperative mean FSFI overall scores were 24.2 and 24.3 respectively (p=0.39). Scores were comparable in all six of the domains assessed by the questionnaire. Particularly, the pre- and postoperative scores for satisfaction were 4.5 and 4.4 respectively. No increase in dyspareunia was observed after surgery, nor was it more difficult for our patients to reach orgasm after the intervention. No statistically significant differences were observed between the pre- and postoperative FSFI scores., Conclusions: Although preliminary, our results suggest that laparoscopic nephrectomy with vaginal extraction has no effect on the sexual quality of life of patients., (Copyright © 2015 Elsevier Masson SAS.

Objective: To assess the feasibility of laparoscopic nephrectomy with vaginal extraction in an ambulatory setting., Methods: Two patients underwent a laparoscopic (1 was robot assisted) nephrectomy with vaginal extraction for a nonfunctioning kidney in an ambulatory setting. Both interventions were performed by the same surgical team comprising a urologic surgeon and a gynecologic surgeon. The operative specimen was vaginally extracted via an incision in the posterior fornix at the end of the intervention. Patients had to respect very strict socioenvironmental and clinical criteria. Anesthesia was achieved using short-acting agents. Only first- and second-step analgesics were used (morphine-free protocol). The main judgment criteria were visual analog scale assessment for postoperative pain, the Clavien-Dindo classification for surgical complications, and the hospital readmission rate., Results: Two female patients (37 and 41 years old) have been successfully operated with this technique. No major perioperative or postoperative complications (Clavien-Dindo grade >2) were reported, and no patient readmission was required. Postoperative pain was well managed with visual analog scale scores ≤ 5. Both patients operated in the ambulatory setting had Chung scores of 10 before their discharge., Conclusion: Laparoscopic or robotic nephrectomy with vaginal extraction can be performed in an ambulatory setting in carefully selected patients. The association of fast-track surgical techniques and vaginal extraction by eliminating the abdominal wound extraction source of postoperative pain allows performing this operation in this setting with a high level of satisfaction., (Copyright © 2014 Elsevier Inc.

Objective: To evaluate the feasibility and morbidity of laparoscopic nephrectomy in patients with autosomal dominant polycystic kidney disease (ADPK)., Patients and Method: This is a retrospective multi-centre study (University Hospitals of Lyons, Toulouse, Nantes and Rennes). Sixty-eight patients who had undergone laparoscopic nephrectomy for polycystic kidney disease between November 1999 and May 2009 were included. This involved unilateral nephrectomy 64 cases, one-stage bilateral in one case and two-stage bilateral in three cases., Results: The mean operating time was 218±74min (100-420) Conversion was necessary in 7 cases. The mean weight of the removed kidney was 1291±646g (240-3400). We regret to report 20 postoperative complications, including one death on postoperative day 50, following an abscess in the renal pelvis, 6 retroperitoneal haemoatomas and 5 arteriovenous fistula thromboses. Postoperative analgesia involved PCA treatment with morphine for a mean period of 1.59±0.8 days (0.5-4). The mean length of hospital stay was 8.3±6.1 days (3-50)., Conclusion: This study shows the feasibility of the laparoscopic approach for nephrectomy in ADPK. This procedure should be performed by experienced laparoscopic surgeons. Indeed, the complication rate is moderate but there is still a risk of severe complications., Level of Evidence: 5., (Copyright © 2013. Published by Elsevier Masson SAS.)

Purpose: To study the feasibility and to present results of laparoscopic nephrectomy with vaginal extraction in overweight or obese patients., Patients and Methods: Three patients having BMI>28 kg/m(2) underwent surgery. Median age was 56 years, median BMI was 44.4. Medical history included for the three patients type 2 diabetes mellitus and arterial hypertension. Two of the three patients were multiparous, one was nulliparous. Patients underwent standard laparoscopic nephrectomy with vaginal extraction of the specimen through a short incision of the posterior vaginal fornix. Feeding was normal on the first operating day. No morphine was prescribed during hospitalization stay., Results: No intraoperative complication occurred. Mean procedure time was 224 min. Mean blood loss was 140 mL. Postoperative period was uneventful and walking was normal on the first operating day. Hospitalization stays were 2, 3 and 5 days. One month follow up found no complication including normal sexual activity., Conclusion: Laparoscopic nephrectomy with vaginal extraction is a feasible technique in obese or overweight patients. Wound morbidity (infection, hernia) is reduced due to the small abdominal incisions., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

Objective: • To assess, in a risk/benefit analysis, the additional risk for complications and benefits of extending the indications and anatomical limits of pelvic lymph node dissection (PLND)., Patients and Methods: • In total, 971 consecutive patients with clinically localized prostate cancer underwent laparoscopic radical prostatectomy from 2003-2007. • Before 1 February 2005, patients with a nomogram probability of lymph node invasion (LNI) <2% did not undergo PLND (No PLND group), whereas those with a LNI ≥ 2% had a PLND limited to the external iliac nodal group (limited PLND group). • After 1 February 2005, all patients underwent a standard PLND including the external iliac, hypogastric and obturator fossa nodal groups (standard PLND group). • The risk parameters were PLND-related complications and operating time. Complications were graded using a modified Clavien classification. The benefit was the detection of nodal metastases., Results: • In the subgroup of patients with a LNI ≥ 2%, standard PLND was a superior operation than the limited PLND in detecting nodal metastases (14.3% vs 4.5%, respectively; P = 0.003). • The risk/benefit of standard vs limited PLND would be one additional grade 3 complication per 20 additional patients with nodal metastases. In the subgroup of patients with LNI <2%, three patients (1.0%) had positive nodes after a standard PLND. • The risk/benefit of standard PLND vs no PLND would be one additional grade 3 complication per three or four additional patients with nodal metastasis. The no PLND group was associated with the lowest risk of grade 1, 2 and 3 complications compared to either the limited or standard PLND groups (P < 0.001)., Conclusions: • In patients with LNI ≥ 2%, standard PLND detects more nodal metastasis. PLND is associated with higher but non-prohibitive complications rate. • The present study found no evidence that the incidence of complications would be reduced by a limited PLND., (© 2010 THE AUTHORS.

The concomitant increase in life expectancy and the incidence of kidney cancers will result in an increase in kidney cancers in subjects over 75 years of age in the coming years. A wait-and-see attitude in cases of voluminous tumors, particularly symptomatic tumors, may well alter the quality of life of these patients through chronic abdominal pain, macroscopic hematuria, or alteration of the general condition due to metastatic progression. Curative or palliative surgical management can be envisioned and should be discussed in the multidisciplinary consensus meeting. Before validating the indication for nephrectomy in the elderly patient, a preoperative geriatric assessment should be made. Moreover, preoperative renal function should be carefully evaluated to measure the risk of terminal renal failure. The reduction in the mean duration of the hospital stay provided by laparoscopic surgery allows patients to return home or to their institution more quickly, an important consideration in the rehabilitation of these patients, who are very sensitive to such changes. Laparoscopic nephrectomy, with evidence in the literature of reduced morbidity and satisfactory oncological results, could therefore be superior to open surgery when indicated and technically feasible., ((c) 2009 Elsevier Masson SAS.
