Stentless florence robotic intracorporeal neobladder (FloRIN), a feasibility prospective randomized clinical trial.

INTRODUCTION: Aim of the study was to evaluate perioperative, postoperative and mid-term functional outcomes of Florence intracorporeal neobladder (FloRIN) configuration technique performed with stentless procedure. MATERIALS AND METHODS: This single institution randomized 1:1 prospective series included consecutive patients treated with Robot-Assisted Radical Cystectomy (RARC) and FloRIN reconfiguration from January 2021 to February 2022. Postoperative complications were graded according to Clavien Dindo classification and divided in early (<30 days from discharge) and delayed (>30 days). RESULTS: Overall, 63 patients were included in the analysis. Among these 32 (50.8 %) were treated with RARC + stentless FloRIN while 31 (49.2 %) underwent stent placement procedure. No differences were found in terms of baseline characteristics between the two groups. Stentless procedure was associated with significant shorter console time 328 vs 374 min (p = 0.04) and lower estimated blood loss (EBL) 330 vs 350 ml (p = 0.04) comparing to stent group. As regards perioperative features, no significant differences were recorded in terms of canalization (p = 0.58) and time to drainage removal (p = 0.11) while a shorter length of hospital stay was found in case of stentless procedure (p = 0.04). Early postoperative complications Clavien ≥ 3a occurred in 9.3 % and 12.9 % of patients while delayed major complications were recorded in the 3.1 % and 9.6 % of patients treated with stentless and stent FloRIN, respectively (p = 0.09). As regards the mid-term functional outcomes, no differences were found in terms of kidney function loss in both 3rd and 6th month assessment (p = 0.13 and p = 0.14, respectively). CONCLUSIONS: In conclusion, Stentless FloRIN is a feasible and safe IntraCorporeal Neobladder technique, as confirmed by the worthy functional and perioperative outcomes achieved in comparison with the standard FloRIN ureteral management strategy.

Holmium laser enucleation of the prostate (HoLEP) is safe and effective in patients with high comorbidity burden

ABSTRACT Introduction We assessed the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) in patients with high comorbidity burden. Materials and methods Data from patients treated with HoLEP at our academic referral center from March 2017 to January 2021 were prospectively collected. Patients were divided according to their CCI (Charlson Comorbidity Index). Perioperative surgical data and 3-month functional outcomes were collected. Results Out of 305 patients included, 107 (35.1%) and 198 (64.9%) were classified as CCI ≥ 3 and < 3, respectively. The groups were comparable in terms of baseline prostate size, symptoms severity, post-void residue and Qmax. The amount of energy delivered during HoLEP (141.3 vs. 118.0 KJ, p=0.01) and lasing time (38 vs 31 minutes, p=0.01) were significantly higher in patients with CCI ≥ 3. However, median enucleation, morcellation and overall surgical time were comparable between the two groups (all p>0.05). Intraoperative complications rate (9.3% vs. 9.5%, p=0.77), median time to catheter removal and hospital stay were comparable between the two cohorts. Similarly, early (30 days) and delayed (>30 days) surgical complications rates were not significantly different between the two groups. At 3-month follow up, functional outcomes using validated questionnaires did not differ between the two groups (all p>0.05). Conclusions HoLEP represents a safe and effective treatment option for BPH also in patients with high comorbidity burden.

Patterns and Predictors of Optimal Surgical and Functional Outcomes after Holmium Laser Enucleation of the Prostate (HoLEP): Introducing the Concept of "Trifecta".

PURPOSE: The present study sought to provide reproducible and patient-oriented metrics to assess the rate of "successful" outcomes (Trifecta) following holmium laser enucleation of the prostate (HoLEP). Clinical and surgical predictors of failure to achieve Trifecta were investigated. MATERIALS AND METHODS: We queried our prospectively collected database of all patients treated with HoLEP between March 2017 and January 2021. Trifecta was defined as the contemporary presence of: (1) no postoperative complication within 3 months; (2) no urinary incontinence at 3-months follow-up; and (3) 3-month postoperative max flow-rate >15 mL/s. Cases were grouped according to Trifecta achievement. All surgical procedures were carried out by a single surgeon. Surgical experience was divided into two different eras according to the number of procedures conducted (surgical era). Multivariate logistic regression analysis was performed to assess predictors of Trifecta failure. RESULTS: Overall 305 patients were included. Of these, 192 patients (63.0%) achieved Trifecta. Preoperative patient-related features were comparable between the two groups, except for a higher post-void residual (PVR) in non-Trifecta patients (median 180 vs. 130 mL, p=0.003). A significant proportion of Trifecta patients (88.5%) were treated in the second surgical era and in 126 (65.6%) cases an en-bloc enucleation was performed. Multivariate analysis confirmed PVR ≥250 mL, first surgical era and standard three-lobes enucleation technique as independent predictors of Trifecta failure. CONCLUSIONS: In our experience the rate of "successful" HoLEP, defined according to our newly introduced Trifecta metric, was 63.0%. We demonstrated that surgical strategy together with rising experience and baseline PVR are key elements to forecast the outcomes.

Robotic Partial Nephrectomy with En Bloc Removal of a Renal Vein Thrombus for Multiple cT3a Renal Cell Carcinoma Lesions.

Partial nephrectomy (PN) may be recommended for selected patients with advanced-stage (>cT2) renal cell carcinoma (RCC) with the aim of avoiding dialysis and chronic kidney disease-related comorbidities. The spread of robotic surgery has led to expansion of PN indications to more challenging scenarios and even frontier surgeries, including advanced-stage RCC. Here we describe the management of a patient with a solitary kidney diagnosed with multiple cT3a (renal vein thrombus) RCC who was treated using a conservative robotic approach. The most crucial surgical considerations for this procedure were: (1) tailored planning of the surgical approach using three-dimensional reconstruction software; (2) accurate boundary delineation for the tumors and thrombus; (3) avoiding unnecessary warm ischemia time; (4) performing an anatomical excision to follow eventual tumor bulging; and (5) en bloc removal of the main lesion and its thrombus. No perioperative complications were recorded. Histopathology revealed clear cell RCC for all four lesions with nucleolar grade 3 and negative surgical margins. At 12-mo follow-up the patient was disease-free. When performed by an experienced surgeon, PN plus venous thrombus excision for imperative cases with cT3 RCC may represent a valid treatment option with valuable oncological and functional outcomes. Patient summary: We describe the case of patient who had a single kidney with multiple kidney tumors and tumor extension into a blood vessel. The patient was treated with robot-assisted removal of the tumors, sparing as much kidney tissue as possible. This technique was found to be safe and effective, with no complications and good intermediate-term results.

Robot assisted radical cystectomy with Florence Robotic Intracorporeal Neobladder (FloRIN): Functional and urodynamic features compared with a contemporary series of open Vescica Ileale Padovana (VIP).

INTRODUCTION: FloRIN reconfiguration technique was introduced in 2016 according to the IDEAL-Collaboration Guidelines, with the attempt to conjugate the advantages of both intracorporeal neobladder and robotic assistance. Herein we report functional outcomes of FloRIN reservoir, specifically focusing on urodynamic features. MATERIALS AND METHODS: Consecutive patients treated with RARC and FloRIN reconstruction were prospectively collected from February 2016 to June 2020. Only patients with a minimum 6-month follow up were analyzed to obtain a stable grade of neobladder maturation before performing the urodynamic study (UDS). The FACT-BL and the QLQ-C30 EORTC questionnaires were used to evaluate urinary function and health-related QoL. Results were compared with a contemporary series of patients treated at the same Institution with open radical cystectomy (ORC) and Vescica Ileale Padovana (VIP). RESULTS: One hundred patients entered the study and 69 patients had complete functional data. Overall, 52 (75.4%) patients reached the daytime continence. Among these, 28 (40.6%) were dry (no pads during daytime), while 24 (34.8%) used one pad/12 h. Night-time continence was achieved by 45 (65.2%) patients. Complete UDS findings were available for 28 patients. No statistically significant differences were found with the VIP-ORC group except for neobladder compliance, being higher in the FloRIN group (p = 0.03). When evaluating QoL scores, RARC with FloRIN reconfiguration showed a better continence recovery, as well as a higher improvement in urgency domain (p = 0.01), psychological status (0.02) and physical self-acceptance (p = 0.02), compared to the VIP-ORC group. CONCLUSIONS: The FloRIN technique showed excellent functional outcomes when compared to the referral VIP-ORC procedure.

Surgical Management of Synchronous, Bilateral Renal Masses: A 1-decade Referral Center Experience.

BACKGROUND: Management and decision-making in patients with bilateral renal masses are controversial. OBJECTIVE: To report our experience of surgical management in patients with bilateral renal masses undergoing surgery at a high-volume center. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively collected data from patients treated with partial nephrectomy (PN) or radical nephrectomy for bilateral renal masses at a single referral institution between June 2008 and June 2019. Patient- and tumor-related features, timing (one vs two stage), and surgical approach (open vs robotic) were analyzed. SURGICAL PROCEDURE: A one- versus two-stage strategy was adopted according to the opportunity to perform at least one PN using a clampless or selective-clamping approach, in order to avoid acute kidney injury. MEASUREMENTS: Operative time, warm ischemia time, and intra- and postoperative complications were recorded. Histopathological results and tumor histology were assessed. RESULTS AND LIMITATIONS: Overall, 41 patients were included. The median age was 67 yr and the median preoperative estimated glomerular filtration rate (eGFR) was 84 ml/min/1.73 m2. The median Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) score was 8 (interquartile range [IQR] 7-8) for both sides. In 17 (42%) patients, a simultaneous approach was chosen, with a pure robotic approach in 11/17 cases, while among the 24 (58.6%) patients treated with a two-stage strategy, 15 (62.5%) were treated with a robotic approach on both sides. Intraoperative complications and postoperative major (CDC ≥3) complications were recorded in 7.3% and 4.9% of cases, respectively. The overall positive surgical margins rate was 2.4%. At a median follow-up of 42 (IQR 18-59) mo, the median eGFR was 73 (IQR 64-80) ml/min/1.73 m2, while disease-free survival and cancer-specific mortality were 90.2% and 7.3%, respectively. CONCLUSIONS: Our experience underlines that both simultaneous and staged surgical treatment of patients with bilateral renal masses are feasible and safe if grounded on proper patient selection. PATIENT SUMMARY: Management of patients with bilateral renal masses is challenging, given the heterogeneity of clinical scenarios and the need to optimize the timing of treatment to achieve maximal functional preservation while ensuring oncological efficacy.

Holmium laser ablation of the prostate (HoLAP) with moses technology for the surgical treatment of benign prostatic hyperplasia

ABSTRACT Purpose: The expansion of technology is leading to a paradigm shift in several urological fields (1, 2). In particular, the adoption of lasers within the surgical treatment of patients with benign prostatic hyperplasia (BPH) is considered one of the most relevant innovations (3-5). In this video, we aimed to report our experience with holmium laser for the ablation of the prostate (HoLAP) in patients with obstructive lower urinary tract symptoms (LUTS) due to BPH. Materials and Methods: From 2018 to 2020, 10 patients with obstructive LUTS secondary to BPH were treated at our Institution with HoLAP (120W Holmium laser Lumenis® with Moses® technology). Main inclusion criteria were: 1) International Prostate Symptom Score ≥12; 2) prostate volume ≤65mL, 3) maximal flow rate (Qmax) ≤15ml/s at preoperative non-invasive uroflowmetry. Results: Mean patient age was 65 (range: 59-72) years. Preoperative mean prostate volume was 50 (range: 35-65) mL. Mean operative time was 66 (range: 45-85) minutes with a mean laser time/operative time ratio of 0.51 (range: 0.44-0.60). Voiding symptoms, Qmax and post voiding residual were significantly improved after 3 and 12 months (all p <0.05). No postoperative urinary incontinence was detected. Conclusions: The present findings suggest that HoLAP is a slightly time-spending procedure, thus its use should be limited to prostate volume <70-80mL. However, no postoperative complications were recorded at all. This technique showed to be a safe option in patients with low-intermediate prostate volume, also in patients whose antiaggregant/anticoagulant therapy is maintained.
