Outcomes in robot-assisted partial nephrectomy for imperative vs elective indications.

OBJECTIVES: To assess and compare peri-operative outcomes of patients undergoing robot-assisted partial nephrectomy (RAPN) for imperative vs elective indications. PATIENT AND METHODS: We retrospectively reviewed a multinational database of 3802 adults who underwent RAPN for elective and imperative indications. Laparoscopic or open partial nephrectomy (PN) were excluded. Baseline data for age, gender, body mass index, American Society of Anaesthesiologists score and PADUA score were examined. Patients undergoing RAPN for an imperative indication were matched to those having surgery for an elective indication using propensity scores in a 1:3 ratio. Primary outcomes included organ ischaemic time, operating time, estimated blood loss (EBL), rate of blood transfusions, Clavien-Dindo complications, conversion to radical nephrectomy (RN) and positive surgical margin (PSM) status. RESULTS: After propensity-score matching for baseline variables, a total of 304 patients (76 imperative vs 228 elective indications) were included in the final analysis. No significant differences were found between groups for ischaemia time (19.9 vs 19.8 min; P = 0.94), operating time (186 vs 180 min; P = 0.55), EBL (217 vs 190 mL; P = 0.43), rate of blood transfusions (2.7% vs 3.7%; P = 0.51), or Clavien-Dindo complications (P = 0.31). A 38.6% (SD 47.9) decrease in Day-1 postoperative estimated glomerular filtration rate was observed in the imperative indication group and an 11.3% (SD 45.1) decrease was observed in the elective indication group (P < 0.005). There were no recorded cases of permanent or temporary dialysis. There were no conversions to RN in the imperative group, and seven conversions (5.6%) in the elective group (P = 0.69). PSMs were seen in 1.4% (1/76) of the imperative group and in 3.3% of the elective group (7/228; P = 0.69). CONCLUSION: We conclude that RAPN is feasible and safe for imperative indications and demonstrates similar outcomes to those achieved for elective indications.

Trifecta Outcomes of Partial Nephrectomy in Patients Over 75 Years Old: Analysis of the REnal SURGery in Elderly (RESURGE) Group.

BACKGROUND: Partial nephrectomy (PN) in elderly patients is underutilized with concerns regarding risk of complications and potential for poor outcomes. OBJECTIVE: To evaluate quality and functional outcomes of PN in patients >75 yr using trifecta as a composite outcome of surgical quality. DESIGN, SETTING, AND PARTICIPANTS: Multicenter retrospective analysis of 653 patients aged >75 yr who underwent PN (REnal SURGery in Elderly [RESURGE] Group). INTERVENTION: PN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary outcome was achievement of trifecta (negative margin, no major [Clavien ≥3] urological complications, and ≥90% estimated glomerular filtration rate [eGFR] recovery). Secondary outcomes included chronic kidney disease (CKD) stage III and CKD upstaging. Multivariable analysis (MVA) was used to assess variables for achieving trifecta and functional outcomes. Kaplan-Meier survival analysis (KMA) was used to calculate renal functional outcomes. RESULTS AND LIMITATIONS: We analyzed 653 patients (mean age 78.4 yr, median follow-up 33 mo; 382 open, 157 laparoscopic, and 114 robotic). Trifecta rate was 40.4% (n=264). Trifecta patients had less transfusion (p<0.001), lower intraoperative (5.3% vs 27%, p<0.001) and postoperative (25.4% vs 37.8%, p=0.001) complications, shorter hospital stay (p=0.045), and lower ΔeGFR (p <0.001). MVA for predictive factors for trifecta revealed decreasing RENAL nephrometry score (odds ratio [OR] 1.26, 95% confidence interval 1.07-1.51, p=0.007) as being associated with increased likelihood to achieve trifecta. Achievement of trifecta was associated with decreased risk of CKD upstaging (OR 0.47, 95% confidence interval 0.32-0.62, p<0.001). KMA showed that trifecta patients had improved 5-yr freedom from CKD stage 3 (93.5% vs 57.7%, p<0.001) and CKD upstaging (84.3% vs 8.2%, p<0.001). Limitations include retrospective design. CONCLUSIONS: PN in elderly patients can be performed with acceptable quality outcomes. Trifecta was associated with decreased tumor complexity and improved functional preservation. PATIENT SUMMARY: We looked at quality outcomes after partial nephrectomy in elderly patients. Acceptable quality outcomes were achieved, measured by a composite outcome called trifecta, whose achievement was associated with improved kidney functional preservation.

Ten-Year Oncologic Outcomes Following Robot-Assisted Radical Cystectomy: Results from the International Robotic Cystectomy Consortium.

PURPOSE: Radical cystectomy is the gold standard for nonmetastatic muscle invasive bladder cancer and for refractory nonmuscle invasive disease. Compared to open radical cystectomy, robot-assisted radical cystectomy has been shown to provide comparable early oncologic outcomes and improved perioperative outcomes. However, there is a paucity of data on long-term oncologic outcomes and concerns about a higher incidence of local recurrence after robot-assisted radical cystectomy. We report 10-year oncologic outcomes following robot-assisted radical cystectomy using a multinational database. MATERIALS AND METHODS: We retrospectively reviewed the prospective International Robotic Cystectomy Consortium database. Consecutive patients who underwent robot-assisted radical cystectomy 10 years ago or earlier were included in analysis. Data were reviewed for demographics, and perioperative, pathological and oncologic outcomes. Kaplan-Meier curves were used to depict recurrence-free, disease specific and overall survival. Multivariate stepwise Cox regression models were applied to identify variables associated with recurrence-free, disease specific and overall survival. RESULTS: We identified 446 patients with a median age of 67 years (IQR 59-76). Of the patients 10% received neoadjuvant chemotherapy, 51% experienced any complication, 23% had high grade complications and 4% died within 3 months of robot-assisted radical cystectomy. Disease was pT3 or greater in 43% of patients and pN+ in 24% while a positive soft tissue surgical margin was observed in 7%. At a median followup of 5 years (IQR 2-10, maximum 14) local and distant recurrence had developed in 15% and 29% of patients, respectively. Ten-year recurrence-free, disease specific and overall survival rates were 59%, 65% and 35%, respectively. Patients with pT3 or greater and pN+ disease showed worse recurrence-free, disease specific and overall survival. CONCLUSIONS: Long-term oncologic outcomes, and recurrence rates and patterns after robot-assisted radical cystectomy seem comparable to those in open series. Advanced disease stage and positive surgical margins remain the main determinants of survival after radical cystectomy.

Cirugía adrenal por Puerto único / Laparoendoscopic single site adrenal surgery

Laparoscopic adrenal surgery is a standard procedure for the management of benign adrenal pathology and small malignant tumors. There has been an increasing interest over the last few years in the use of laparoendoscopic single-site surgery (LESS). From recent literatures, LESS adrenalectomy was demonstrated that this technique was safe and feasible despite the relatively difficult anatomical location of the adrenal gland. We reviewed the surgical techniques and outcomes of LESS adrenalectomy including robot-assisted approach and gave an overview of the current role of LESS in adrenalectomy(AU)

La cirugía suprarrenal laparoscópica es un procedimiento estándar en el tratamiento de la patología adrenal benigna y de los tumores malignos pequeños. Ha habido un interés creciente durante los últimos años en la utilización de cirugía laparoscópica por puerto único (LESS). Según la literatura reciente se ha demostrado que la adrenalectomía LESS es una técnica segura y viable a pesar de la localización anatómica relativamente difícil de la glándula suprarrenal. Revisamos las técnicas quirúrgicas y los resultados de la adrenalectomía LESS incluyendo el abordaje asistido por robot y damos una visión de conjunto del papel actual del puerto único en la adrenalectomía(AU)
