Trifecta Rate Research Articles

Achieving trifecta outcomes in robotic-assisted partial nephrectomy within a fellowship training centre.

To assess the robotic-assisted partial nephrectomy (RAPN) trifecta rate within a fellowship program. Patients undergoing RAPN 01/01/2010-01/07/2023 were enrolled from a prospectively maintained database. All cases were performed jointly with surgical fellows, except when privately insured. Patients were excluded if they were converted to open or radical nephrectomy. The primary outcome was achieving the 'trifecta' of negative surgical margins, no complications < 30 days post-operatively and warm ischaemia time (WIT) < 25 min. The secondary outcomes were factors associated with trifecta success. Ethics approval was obtained.In the enrolment period, 355 patients underwent intended RAPN, of whom seven were excluded due to conversion to conversion to radical nephrectomy (6 patients) or conversion to open (one). Amongst the 348 eligible patients, median age was 60 years, 115 (33%) were female and 19 were private patients. WIT was < 25 min for 324/337 patients (96%), surgical margins were negative in 325 (93%), 294 (84%) were complication-free at 30 days and 301/320 (94%) had a < 30% decline in estimated glomerular filtration rate at 3-6 months postoperatively. Subsequently, trifecta outcomes were achieved in 253/337 (75%) patients. Comparing with patients without those with trifecta success were similar in all thirteen measured patients and tumour factors. In a teaching hospital, with a fellowship training programme, trifecta outcome is achievable for most RAPN patients, and at a rate comparable to international standards. Fellowship centres should monitor their outcomes to ensure high patient outcomes are maintained alongside training requirements.

Surgical Outcomes of Hugo™ RAS Robot-Assisted Partial Nephrectomy for Cystic Renal Masses: Technique and Initial Experience.

Background: The Hugo™ Robot-Assisted Surgery (RAS) system is a new cutting-edge robotic platform designed for clinical applications. Nevertheless, its application for cystic renal tumors has not yet been thoroughly investigated. In this context, we present an initial series of Robot-Assisted Partial Nephrectomy (RAPN) procedures carried out using the Hugo™ RAS system for cystic renal masses. Methods: Between October 2022 and January 2024, twenty-seven RAPN procedures for renal tumors were performed at Fondazione Policlinico Universitario Campus Bio-Medico. Our prospective board-approved dataset was queried for "cystic features" (n = 12). Perioperative data were collected. The eGFR was calculated according to the CKD-EPI formula. Post-operative complications were reported according to the Clavien-Dindo classification. Computed tomography (CT) scans for follow-up were performed according to the EAU guidelines. Trifecta was defined as the coexistence of negative surgical margin status, no Clavien-Dindo grade ≥ 3 complications, and eGFR decline ≤ 30%. Results: All the patients successfully underwent RAPN without the need for conversion or additional port placement. The median docking and console time were 5.5 (IQR, 4-6) and 79.5 min (IQR, 58-91 min), respectively. No intraoperative complications occurred, as well as clashes between instruments or with the bedside assistant. Two minor postoperative complications were recorded (Clavien-Dindo II). At discharge, serum creatinine and eGFR were comparable to preoperative values. Only one patient (8.4%) displayed positive surgical margins. The rate of trifecta achievement was 91.7%. Conclusions: RAPN for cystic renal masses using the novel Hugo™ RAS system can be safely and effectively performed. This robotic system provided satisfactory peri-operative outcomes, preserving renal function and displaying low postoperative complications and a high trifecta rate achievement.

Da Vinci and Hugo RAS Platforms for robot-assisted partial nephrectomy: a preliminary prospective comparative analysis of the outcomes.

Robot-assisted partial nephrectomy (RAPN) has emerged as the preferred approach for T1 renal-cell-carcinoma. As new robotic platforms like Hugo RAS emerge, we seek to understand their potential in achieving similar RAPN outcomes as the established Da Vinci system. A prospective single-center comparative study was conducted, and 50 patients selected for RAPN were enrolled (25 Da Vinci Xi; 25 Hugo RAS). The choice of robotic system was based solely on hospital logistics criteria. Surgeries were performed by expert surgeons. Demographic data, tumor characteristics, operative details and postoperative outcomes were collected. SPSS version 22.0 was used for statistical analyses. The average age of patients was 62.52±9.47 years, with no significant differences in median age, sex, and nephrometry scores between groups. Da Vinci group showed a significantly shorter docking time (12.56 vs. 20.08 min; P<0.01), while other intraoperative measures like console time and warm ischemia time were similar. The Hugo RAS group had a shorter renorraphy time (14.33 vs. 18.84 min; P=0.024). Postoperative outcomes and surgical margin positivity showed no significant differences. Each group had one patient (4%) who developed major surgical complications (Clavien IIIa). Trifecta rates were comparable between both groups (Da Vinci 88% vs. Hugo RAS 84%; P=0.93). Initial findings suggest similar perioperative outcomes for RAPN when using Hugo RAS compared to the Da Vinci system. Further research with long-term follow-up is necessary to evaluate oncological and functional outcomes.

Learning curve for intracorporeal robotic Padua ilealbladder: 10-year functional assessment from a high-volume single-centre series.

To assess the impact of the learning curve (LC) on perioperative and long-term functional outcomes of a consecutive single-centre series of robot-assisted radical cystectomy with Padua intracorporeal orthotopic neobladder. Patients treated between 2013 and 2022 were included, with ≥1 year of follow-up. The entire cohort was divided in tertiles. Categorical and continuous variables were compared. Joinpoint regression analysis was used to identify significant changes over the decade in linear slope of the 1-year day- and night-time continence. Uni- and multivariable Cox regression analyses identified predictors of day- and night-time continence recovery. Day-time continence was defined as 'totally dry' (no pads), night-time continence as pad wetness ≤50 mL (one safety pad). Overall, 200 patients were included. The mean hospital stay (P = 0.002) and 30-day complications (P = 0.04) significantly reduced over time; the LC significantly impacted on Trifecta achievement (P < 0.001). The 1-year day- and night-time continence probabilities displayed a significant improving trend (day-time continence annual average percentage change [AAPC] 11.45%, P < 0.001; night-time continence AAPC 10.05%, P = 0.009). The LC was an independent predictor of day- (hazard ratio [HR] 1.008; P < 0.001) and night-time continence (HR 1.004; P = 0.03) over time. Patients at the beginning of the LC had significantly longer hospitalisations, more postoperative complications, and lower Trifecta rates. At the 10-year analyses, we observed a significant improving trend for both the 1-year day- and night-time continence probabilities, highlighting the crucial role of the LC. However, we are unable to assess the case volume needed to achieve a plateau in terms of day- and night-time continence rates.

Comparison of perioperative and short-terms outcomes of en-bloc Holmium laser enucleation of the prostate (HoLEP) and robot-assisted simple prostatectomy: a propensity-score matching analysis.

Surgical treatment of symptomatic benign prostatic hyperplasia (BPH) has seen an evolution during the last decades. On one hand, en-bloc HoLEP emerged as a valid endoscopic treatment regardless prostate size. On the other hand, robot-assisted simple prostatectomy (RASP) has gained attention in larger prostates showing encouraging results. Herein, for the first time in the scientific scenario, we sought to compare the outcomes of RASP and en-bloc HoLEP cases after propensity-score matching (PSM) analysis. We retrospectively queried our prospectively database of patients treated with HoLEP or RASP between 2017 and 2022 among two high-volume centers. PSM was applied based on the International Prostate Symptom Score (IPSS) questionnaire, prostate volume and max-flow rate. All procedures were performed by a single surgeon per center. Outcomes were assessed at 1, 3, and 6-month postoperatively and therefore annually. Trifecta definition was used to assess "success" in surgical procedures and was defined as the contemporary presence of: a) no postoperative complications within the first postoperative month; b) 1-month postoperative Qmax >15 ml/s and c) no urinary incontinence at 3-month evaluation. Overall, 48 HoLEP and 47 RASPs were matched. Operative time, hospitalization time (median 4 vs 5 days) and catheterization time (median 3 vs 2 day) were found to be shorter in the HoLEP group as compared to the counterpart (p < 0.05). Early postoperative complication rate was also lower in the HoLEP cohort (6.2% vs 12.6%; p = 0.03) as well as postoperative haemoglobine blood level drop (1.4 vs 2.4 g/dL; p = 0.03). On the other hand, postoperative antegrade ejaculation (55.3% vs 6.8%) 1-month max flow (median 28 vs 24 ml/sec) and continence rates (0% vs 20.8%) favored RASP (p < 0.05). Overall, Trifecta rate was similar in the two groups (76.1% vs 82.6%). Both HoLEP and RASP are safe and effective treatments for symptomatic BPH. HoLEP demonstrated to have lower perioperative risks while is affecting by a higher probability of transient early UI. On the other hand, RASP is more effective in reducing postoperative ejaculatory dysfunction.

683 Closed Loop Regional Audits on Quality Predictive Indicators for Renal Cell Carcinoma Management in Northern Ireland

Abstract Aim To conduct a full cycle Regional Audit in Northern Ireland to assess the ten Quality Predictive Indicators (QPI) in the management of Renal Cell Carcinoma (RCC) as per National Cancer Quality Steering Group (NCQSG) of NHS Scotland. Each cycle lasted for 6 months. Method QPIs were assessed in four major domains such as radiological, histological, surgical and pre-treatment performance indicators in the management of RCC. Using the Northern Ireland Electronic Care record, data were collected, recorded in MS Excel and analysed and arrived at conclusions. The results were compared with NHS Scotland RCC audit reports published in August 2019 and October 2022. Results In audit cycle 1, NCGSQ targets of quality prediction was achieved in 3 QPIs (Nephron Sparing Surgery, Trifecta rate and 30/90 mortality rate) among the 10 QPIs. In Audit Cycle 2, additional 4 NCGSQ targets were achieved namely- pre-treatment CT/MRI, Histodiagnosis in cryotherapy, histodiagnosis in chemotherapy and MDT discussion. Conclusions There has been significant improvement in all QPIs in the management of RCC in Northern Ireland during the audited period. We have achieved NCGSQ quality performance indicator targets in 7 among the 10 QPIs that were audited. Further interventions may be required to achieve targets in QPIs such as Leibovich scoring, pre-treatment TNM staging and prognostic scoring in metastatic RCC.

Long-term oncologic and functional outcomes following robot-assisted radical cystectomy and intracorporeal Padua ileal bladder: results from a single high-volume center.

To report long-term oncologic and functional outcomes of a large consecutive single center series of Robot-assisted radical cystectomy (RARC)- intracorporeal (IC) Urinary Diversion (UD), identifying their predicting factors. A single center Bladder cancer (BC) database was queried for "RARC" and "ICUD", including patients treated between January 2012 and September 2020. Kaplan-Meier curves were assessed disease-free (DFS), cancer-specific (CSS) and overall survival (OS) probability. Univariable (UV) and multivariable (MV) analysis were adopted to identify predictors of DFS, CSS and OS. Kaplan-Meier method evaluated day- and night-time continence recovery probabilities; UV and MV analysis were adopted to identify predictors of Day-time continence. Overall, 251 patients were included. Among them, 192 patients underwent intracorporeal ileal orthotopic neobladder (ION) (76.5%). Five-year DFS, CSS and OS rates were 66.5%, 65.4% and 61.5%; pT stage ≥ 3 and pathologic nodal involvement were identified as negative independent predictors of DFS (HR 2.39, p = 0.001, HR 4.64, p ≤ 0.001), CSS (HR 2.20, p = 0.01, HR 3.97, p < 0.001) and OS (HR 2.25, p = 0.005, HR 3.95, p < 0.001). In RARC-ION patients, Trifecta rate was 64.1%. One-year day- and night-time continence rates were 78.6% and 48.3%. Age (HR 0.98, p = 0.03), female gender (HR 0.57, p = 0.008) and complications Clavien grade ≥ 3 (HR 0.55, p = 0.03) were identified as independent predictors of day-time incontinence. Long-term oncologic outcomes and their predicting factors seem aligned to the largest historical open series and multi-institutional robotic series data. According to the identified predicting factors undermining a proper achievement of day-time continence, this represents an objective support, in order to properly advice specific sub-group of patients.

Comparison of peri- and intraoperative outcomes of open vs robotic-assisted partial nephrectomy for renal cell carcinoma: a propensity-matched analysis

BackgroundPartial nephrectomy (PN) is the gold standard surgical treatment for resectable renal cell carcinoma (RCC) tumors. However, the decision whether a robotic (RAPN) or open PN (OPN) approach is chosen is often based on the surgeon’s individual experience and preference. To overcome the inherent selection bias when comparing peri- and postoperative outcomes of RAPN vs. OPN, a strict statistical methodology is needed.Materials and methodsWe relied on an institutional tertiary-care database to identify RCC patients treated with RAPN and OPN between January 2003 and January 2021. Study endpoints were estimated blood loss (EBL), length of stay (LOS), rate of intraoperative and postoperative complications, and trifecta. In the first step of analyses, descriptive statistics and multivariable regression models (MVA) were applied. In the second step of analyses, to validate initial findings, MVA were applied after 2:1 propensity-score matching (PSM).ResultsOf 615 RCC patients, 481 (78%) underwent OPN vs 134 (22%) RAPN. RAPN patients were younger and presented with a smaller tumor diameter and lower RENAL-Score sum, respectively. Median EBL was comparable, whereas LOS was shorter in RAPN vs. OPN. Both intraoperative (27 vs 6%) and Clavien-Dindo > 2 complications (11 vs 3%) were higher in OPN (both < 0.05), whereas achievement of trifecta was higher in RAPN (65 vs 54%; p = 0.028). In MVA, RAPN was a significant predictor for shorter LOS, lower rates of intraoperative and postoperative complications as well as higher trifecta rates. After 2:1 PSM with subsequent MVA, RAPN remained a statistical and clinical predictor for lower rates of intraoperative and postoperative complications and higher rates of trifecta achievement but not LOS.ConclusionsDifferences in baseline and outcome characteristics exist between RAPN vs. OPN, probably due to selection bias. However, after applying two sets of statistical analyses, RAPN seems to be associated with more favorable outcomes regarding complications and trifecta rates.

Comparing the Outcomes of Open, Laparoscopic & Robotic Partial Nephrectomy: A Network Meta-Analysis.

Renal cell carcinoma (RCC) incidence and mortality are continuing to rise worldwide. To perform a systematic review and network meta-analysis (NMA) to determine the advantages and disadvantages of open (OPN), laparoscopic (LPN), and robotic-assisted partial nephrectomy (RAPN) with particular attention to intra-operative, immediate post-operative, as well as longer term functional and oncologic outcomes. A systematic review was performed as per PRISMA-NMA guidelines. Binary data was compared using odds ratios (ORs). Mean differences (MDs) were used for continuous variables. ORs and MDs were extracted from the articles to compare the efficacy of the various surgical approaches. Statistical validity is guaranteed when the 95% CrI does not include 1. In total, there were 31 studies included in the NMA with a combined 7,869 patients. Of these, 33.7% (2,651/7,869) underwent OPN, 20.8% (1,636/7,869) underwent LPN while 45.5% (3,582/7,689) had RAPN. There was no difference for either LPN or RAPN as compared to OPN in ischaemia time, intra-operative complications, positive surgical margins (PSM), operative time or trifecta rate. Estimated blood loss (EBL), post-operative complications and length of stay (LOS) were all significantly reduced in RAPN when compared with OPN. The outcomes of RAPN and LPN were largely similar except the significantly reduced EBL in RAPN. This systematic review and network meta-analysis suggests that RAPN is the preferable operative approach for patients undergoing surgery for lower-staged RCC.

A Randomized Controlled Study of Robot-Assisted versus 3D Laparoscopic Radical Prostatectomy in Patients with Carcinoma Prostate.

A prospective randomized comparative study was performed from 1st January 2020 to 30th June 2021. All patients included were diagnosed with localized/locally advanced ca prostate. 60 patients fulfilling the inclusion and exclusion criteria were randomized into 2 groups. Groups A and B included patients who underwent robot-assisted radical prostatectomy and 3D laparoscopic transperitoneal radical prostatectomy, respectively. Various demographic, intraoperative, postoperative, and follow-up parameters were collected. Outcomes were evaluated in the form of the trifecta (continence, potency, and BCR-free status) and pentafecta rates (trifecta with no perioperative complications and negative surgical margins) in between the two groups. The mean operative time in Group A was 137.83 mins ± 17.27 compared to 148.20 mins ± 26.16 in Group B. Trifecta rates in Group A and Group B were 43.3%, 63.3%, and 76.6% and 40%, 53.3%, and 70% at 1, 3, and 6 months. Pentafecta rates in Group A and Group B were 36.6%, 53.3%, and 70% and 33.3%, 40%, and 53.3% at 1, 3, and 6 months. Complication rates were 10% in Group A and 13.3% in Group B, respectively. Only one patient in our study (Group B) had a positive surgical margin. We conclude from our comparative study, that both robot-assisted and 3D laparoscopic transperitoneal radical prostatectomy are feasible and efficacious treatment modalities for achieving acceptable trifecta and pentafecta rates in managing ca prostate with earlier continence and shorter urethrovesical anastomosis time in the robotic arm.

Three-dimensional virtual models assistance predicts higher rates of "successful" minimally invasive partial nephrectomy: an Institutional analysis across the available trifecta definitions.

3D virtual models (3DVMs) are nowadays under scrutiny to improve partial nephrectomy (PN) outcomes. Five different Trifecta definitions have been proposed to optimize the framing of "success" in the PN field. Our aim is to analyze if the use of 3DVMs could impact the success rate of minimally invasive PN (mi-PN), according to the currently available definitions of Trifecta. At our Institution 250 cT1-2N0M0 renal masses patients treated with mi-PN were prospectively enrolled. Inclusion criteria were the availability of contrast-enhanced CT, baseline and postoperative serum creatinine, and eGFR. These patients were then compared with a control group of 710 patients who underwent mi-PN with the same renal function assessments, but without 3DVMs. Multivariable logistic regression (MLR) models were used to predict the trifecta achievement according to the different trifecta definitions. Among the definitions, Trifecta rates ranged between 70.8% to 97.4% in the 3DVM group vs. 56.8% to 92.8% in the control group (all p values < 0.05). 3DVMs showed better postoperative outcomes in terms of ΔeGFR, ( - 16.6% vs. - 2.7%, p = 0.03), postoperative complications (15%, vs 22.9%, p = 0.002) and major complications (Clavien Dindo > 3, 2.8% vs 5.6%, p = 0.03). At MLR 3DVMs assistance independently predicted higher rates of successful PN across all the available definitions of Trifecta (OR: 2.7 p < 0.001, OR:2.0 p = 0.0008, OR:2.8 p = 0.02, OR 2.0 p = 0.003). The 3DVMs availability was found to be the constant predictive factor of successful PN, with a twofold higher probability of achieving Trifecta regardless of the different definitions available in Literature.

Over the year, five different Trifecta definitions have been proposed to optimize the framing of “success” in the PN field. The aim of the present study was to analyze if the use of 3DVMs could impact the success rate of minimally-invasive PN, according to the currently available definitions of Trifecta. METHODS: At our Institution 250 cT1-2N0M0 renal masses patients treated with minimally-invasive PN were prospectively enrolled. Inclusion criteria were the availability of contrast-enhanced CT from which a 3DVM was obtained, baseline and postoperative serum creatinine, and eGFR. These patients were then compared with a control group of 710 patients who underwent minimally-invasive PN with the same renal function assessments, but without 3DVMs. Trifecta rate was defined for each of the currently available definitions, after stratification according to 3DVMs availability. Multivariable logistic regression (MLR) models were used to predict the trifecta achievement according to the different trifecta definitions. RESULTS: Overall, 960 patients met the inclusion criteria. Among the definitions, Trifecta rates ranged between 70.8% to 97.4% in the 3DVM group vs. 56.8% to 92.8% in the control group (all p values<0.05). 3DVMs showed better postoperative outcomes in terms of ΔeGFR, (-16.6% vs. -2.7%, p=0.03), postoperative complications (15%, vs 22.9%, p=0.002) and major complications (Clavien Dindo >3, 2.8% vs 5.6%, p=0.03). At MLR 3DVMs assistance independently predicted higher rates of successful PN across all the available definitions of Trifecta (OR: 2.7 p<0.001, OR:2.0 p=0.0008, OR:2.8 p=0.02, OR 2.0 p=0.003). CONCLUSIONS: There was large variability in the rates of Trifecta according to different definitions, but always in favor of those PN assisted by 3DVMs. Their availability was found to be the constant predictive factor of successful PN, with a 2-fold higher probability of achieving Trifecta regardless of the different definitions available in Literature and justifying their introduction in clinical practice.

Sutureless Purely Off-Clamp Robot-Assisted Partial Nephrectomy: Avoiding Renorrhaphy Does Not Jeopardize Surgical and Functional Outcomes.

To compare outcomes of sutureless (SL) vs. renorrhaphy (RR) off-clamp robotic partial nephrectomy (ocRPN), we retrospectively analyzed procedures performed at our center, from January 2017 to April 2021, for cT1-2N0M0 renal masses. All the patients with a minimum follow-up < 1 month were excluded from the analysis. The trifecta rate defined surgical quality. Any worsening from chronic kidney disease (CKD) I-II to ≧ IIIa (from IIIa to ≧ IIIb, and from IIIb to ≧ IV) was considered as significant stage migration (sCKDsm). A 1:1 propensity score-matched (PSM) analysis minimized baseline imbalances between SL and RR cohorts in terms of age, gender, ASA score, baseline estimated glomerular filtration rate (eGFR), tumor size, and RENAL score. Logistic regression analyses identified predictors of trifecta achievement. Kaplan-Meier (KM) analysis assessed the impact of RR on significant chronic kidney disease sCKDsm-free survival (SMFS), while Cox regression analyses identified its predictors. Overall, 531 patients were included, with a median tumor size of 3.5 cm (IQR: 2.7-5); 70 (13%) presented with a cT2 mass. An SL approach was pursued in 180 cases, but 10 needed conversion to RR. After PSM analysis, patients receiving SL showed a higher trifecta rate (94% vs. 84%; p = 0.007). SMFS probabilities were comparable at KM analysis (log-rank = 0.69). Age (OR: 0.97; 95%CI: 0.95-0.99; p = 0.01), a RENAL score ≧ 10 (OR: 0.29; 95%CI: 0.15-0.57; p < 0.001), and RR (OR: 0.34; 95%CI: 0.17-0.67; p = 0.002) were independent predictors of trifecta achievement. Age (OR: 1.04; 95%CI: 1.003-1.07; p = 0.03) and baseline eGFR (OR: 0.99; 95%CI: 0.97-0.99; p = 0.05) independently predicted sCKDsm. Compared to RR, our experience seems to show that the SL approach significantly increased the probabilities of achieving the trifecta in the observed group of cases.

Robotic simple prostatectomy vs HOLEP, a 'multi single-center' experiences comparison.

The aim of this study was to compare peri-operative and mid-term outcomes of patients who underwent robot-assisted simple prostatectomy (RASP) vs holmium laser enucleation of the prostate (HOLEP). RASP and HOLEP are the treatments of choice for men with symptomatic benign prostatic obstruction (BPO) and a prostate ≥80 g, achieving comparable short and mid-term efficacy. No randomized controlled studies have proved the superiority of one technique over the other. The prospectively maintained databases of the participating institutions were queried for patients with a prostate volume (PV) ≥80 g, who underwent surgery for BPO between 2011 and 2021. The study population was divided into two subgroups based on surgical approach. Demographics, baseline characteristics, and 12 months outcomes were compared between groups: χ2 and Student t-tests were used for categorical and continuous variables, respectively. The Trifecta composite outcome (post-operative Q-max >15 ml/sec, International Prostate Symptom Score (IPSS) <8 and absence of complications) was used to define surgical quality and the two groups were compared accordingly. Logistic regression analyses investigated predictors of Trifecta achievement. We included 97 patients with comparable pre-operative features (all p >0.30): 43 underwent RASP, 54 HOLEP. Median PV was 102 g (IQR 89-120) and Q-max was 7.2 ml/s (IQR 5.4-9.0). The Trifecta rate was 43% overall, higher in the RASP subgroup (56% vs 33%; p = 0.02). The endoscopic approach was its only independent predictor (OR 0.5; 95% CI 0.28-0.88; p = 0.016). At univariable regression analysis, surgical approach was the only independent predictor of Trifecta achievement, which was significantly higher in the RASP group compared to HOLEP.

Comparison between Two da Vinci Surgical Systems in Trifecta and Pentafecta Rates for Robot-Assisted Partial Nephrectomy

Purpose: Comparative studies on the outcomes of robot-assisted partial nephrectomy (RAPN) procedures conducted using the da Vinci Xi and Si platforms remain sparse. We retrospectively reviewed and compared the Trifecta and Pentafecta rates of the two robotic surgical platforms. Materials and Methods: A total of 338 patients who had undergone RAPN using da Vinci Si platform or Xi platform were included. Pentafecta was defined herein as Trifecta (a warm ischemia time &lt;25 min, a negative surgical margin, and the absence of significant perioperative complications) with the addition of estimated glomerular filtration rate preservation of over 90% and no chronic kidney disease stage progression by 12 months postsurgery. Multivariate logistic regression analysis was conducted to identify the predictors of Trifecta and Pentafecta achievement. Results: The trifecta and pentafecta rates were higher in the Xi group than in the Si group (65% vs. 29%, P &lt; 0.001 for trifecta; 31% vs. 14%, P = 0.001 for pentafecta). In addition, a significantly shorter average WIT (19 vs. 28 min, P &lt; 0.001) and console time (141 vs. 163 min, P = 0.004) were identified in the Xi group than in the Si group. RAPN conducted using the Xi platform was independently associated with both higher achievement rates of trifecta and pentafecta. In addition, multivariate regression analyses revealed that no history of hypertension, low tumor complexity as measured using the RENAL nephrometry score, anterior orientation of the renal tumor were associated with higher Trifecta rates; while history of diabetes and anterior–posterior renal tumor orientation were the significant predictors of Pentafecta achievement, respectively. Conclusion: A significantly higher rates of trifecta and pentafecta achievement were observed in the Xi group than in the Si group. The use of the Xi platform was also significantly associated with low operative times and acceptable complication rates.

Predictors of trainees' proficiency during the learning curve of robot-assisted radical prostatectomy at high- -volume institutions: results from a multicentric series.

The aim of this series was to evaluate predictors of Proficiency score (PS) achievement on a multicentric series of robot-assisted radical prostatectomies (RARP) performed by trainee surgeons with two different surgical techniques at four tertiary-care centers. Four institutional datasets were merged and queried for RARPs performed by surgeons during their learning curve (LC) between 2010 and 2020 using two different approaches (Group A, Retzius-sparing RARP, n = 164; Group B, standard anterograde RARP, n = 79). Logistic regression analysis was performed to identify predictors of PS achievement for the overall trainee cohort. For all analyses, a two-sided p <0.05 was considered significant. Group B showed significantly increased median operative time, positive surgical margins (PSM) status, increased number of nerve-sparing procedures, shorter LC time (each p <0.04). PS, continence status, potency, biochemical recurrence and 1-year trifecta rates were comparable between groups (each p >0.3). On multivariable analysis, time from LC starting ≥12 months (OR = 2.79; 95%IC [1.15-6.76]; p = 0.02) and a nerve-sparing intent (OR = 3.18; 95%IC [1.15-8.77]; p = 0.02) were independent predictors of PS score achievement (Table 3). Higher PS rates for RARP trainees may be expected after 12 months from LC beginning. Short-term training courses are unlikely to confer proper surgical training, while long-term structured training programs seem to be beneficial on perioperative outcomes.

Nerve-spring technique could achieve a functional trifecta outcome of robotic intracorporeal studer's orthotopic neobladder in the male.

To summarize some key steps of functional improvement in robotic intracorporeal studer's orthotopic neobladder (RISON) of males, especially for nerve-spring technique. We also presented the result of 1-year follow-up aimed to illustrate its functional trifecta outcomes. Robotic radical cystectomy with intracorporeal studer's orthotopic neobladder was performed on 33 male patients by the same surgeon from April 2018 to March 2019. Nerve-sparing technique had been used in 11 of the 33 patients. A prospectively maintained dataset was retrospectively searched and the related perioperative and follow-up data were analyzed. The functional trifecta outcomes referred to the freedom from recurrence, urinary continence and sexual function recovery after one year. A total of 33 males were included in our study. All perioperative information was recorded in detail. Thirty-two cases were confirmed to have negative surgical margin, except one pT3a case. And another case of incidental prostate cancer was diagnosed pathologically. All patients (100%) were recurrence-free one year after the operation. Eleven patients underwent nerve-sparing surgeries, including inter-fascial techniques or intra-fascial techniques. All these patients attained daytime continence (0 pad) at 1 month. With the nighttime continence, nerve-sparing group (2, 2,1) used fewer pads than other 22 cases (3, 3,2) at 1, 6 or 12 month(s) respectively. We defined urinary continence as 0 pad in daytime and no more than 1 pad in nighttime. The median preoperative score of International Index of Erectile Function (IIEF-6) in the 11 cases was 24. The sexual function recovery was defined as IIEF-6 > 20. The final trifecta rate was 54.5% and the median follow-up time lasted 17 months (range, 12 to 22 months). RISON could be a safe and feasible choice of urinary diversion. Nerve sparing techniques might help the patients achieve a relatively higher functional trifecta rate.
