Robot-Assisted Radical Prostatectomy Performed with the Novel Surgical Robotic Platform Hugo™ RAS: Monocentric First Series of 132 Cases Reporting Surgical, and Early Functional and Oncological Outcomes at a Tertiary Referral Robotic Center.

BACKGROUND: Robotic-assisted surgery is the gold standard for performing radical prostatectomy (RARP), with new robotic devices such as HugoTM RAS gaining prominence worldwide. OBJECTIVE: We report the surgical, perioperative, and early postoperative outcomes of RARP using HugoTM RAS. DESIGN, SETTING, AND PARTICIPANTS: Between April 2022 and October 2023, we performed 132 procedures using the Montsouris technique with a four-robotic-arm configuration in patients with biopsy-proven prostate cancer (PCa). OUTCOME MEASURES: We collected intraoperative and perioperative data during hospitalization, along with follow-up data at predefined postoperative intervals of 3 and 6 months. RESULTS AND LIMITATIONS: Lymphadenectomy was performed in 25 procedures, with a bilateral nerve-sparing technique in 33 and a monolateral nerve-sparing technique in 33 cases. The mean total surgery time was 242 (±57) min, the mean console time was 124 (±48) min, and the mean docking time was 10 (±2) min. We identified 17 system errors related to robotic arm failures, 9 robotic instrument breakdowns, and 8 significant conflicts between robotic arms. One post-operative complication was classified as Clavien-Dindo 3b. None of the adverse events, whether singular or combined, increased the operative time. Positive margins (pR1) were found in 54 (40.9%) histological specimens, 37 (28.0%) of which were clinically significant. At 3 and 6 months post-surgery, the PSA levels were undetectable in 94.6% and 92.1% of patients, respectively. Social urinary continence was regained in 86% after 6 months. Limitations of our study include its observational monocentric case-series design and the short follow-up data for functional and oncological outcomes. CONCLUSIONS: Our initial experience highlights the reliability of the HugoTM RAS system in performing RARP. Additionally, we also list problems and solutions found in our daily work.

Value of transrectal color Doppler ultrasound of the common penile arteries in the diagnosis of arteriogenic erectile dysfunction: A pilot study.

BACKGROUND: Penile duplex Doppler ultrasound in combination with intra-cavernous injection of vasoactive agents (PDDU-ICI) is the most accepted tool for diagnosis of arteriogenic erectile dysfunction (AED), but is invasive, time consuming and at risk of side effects. OBJECTIVES: The purpose of this pilot study is to evaluate the potential of transrectal color Doppler ultrasound (TR-CDU) of the common penile arteries as a non-invasive method for the diagnosis of AED. MATERIALS AND METHODS: A consecutive series of 61 men consulting for erectile dysfunction (ED) and 20 controls underwent TR-CDU examination, aged from 40 to 80 years. Sonographic parameters were correlated with the International Index of Erectile Function, short form (IIEF-5). Sensitivity and specificity were calculated and the areas under the receiver operating characteristic curves (AUC) were compared to evaluate the diagnostic performance. RESULTS: Receiver operating characteristic curve analysis showed no significant results for IIEF-5 score ⩾21 in relation to the Doppler parameters. However, we found a good diagnostic performance for patients with ED grading from moderate to severe at IIEF-5. In this cohort, we found that mean peak systolic velocity >15.8 cm/s predicted IIEF-5 ⩾17 (AUC = 0.73, p = 0.002) with 61.5% sensitivity and 85.7% specificity. Mean end diastolic velocity >1.46 cm/s predicted IIEF-5 ⩾17 (AUC = 0.68, p = 0.02) with 80.7% sensitivity and 52.4% specificity. Mean resistance index ⩽0.72 predicted IIEF-5 ⩾17 (AUC = 0.71, p = 0.004) with 46.2% sensitivity and 95.2% specificity. Mean pulsatility index ⩽1.41 predicted IIEF-5 ⩾17 (AUC = 0.75, p = 0.0005) with 48.5% sensitivity and 95.14% specificity. CONCLUSIONS: TR-CDU proved to be a feasible and non-invasive procedure, easily repeatable and not time consuming, overcoming the limits of PDDU-ICI. Diagnostic accuracy seems to be promising in discriminating patients with normal erectile function or mild dysfunction from those with moderate to severe ED. However, these findings need to be verified in future controlled randomized clinical trials.

Feasibility and perioperative outcomes of percutaneous-assisted laparoscopic hysterectomy: A multicentric Italian experience.

OBJECTIVE: This multicentric prospective phase II study aimed to investigate the feasibility, safety, and efficacy of percutaneous-assisted laparoscopic hysterectomy in terms of perioperative outcomes, feasibility, VAS score, and cosmetic outcomes. STUDY DESIGN: Between May 2015 and October 2017, 382 patients were considered eligible for minimally invasive percutaneous-assisted laparoscopic hysterectomy using Percuvance™, Percutaneous Surgical System - PSS, TELEFLEX ltd. Among them, 80 patients (20.9 %) met the inclusion criteria and were enrolled in the study. The coordinator center was the Division of Gynecologic Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. Enrolled patients underwent total percutaneous-assisted laparoscopic hysterectomy ±â€¯bilateral salpingo-oophorectomy ±â€¯nodal assessment. RESULTS: The median age was 52 (range, 32-80) years, and the median body mass index was 25 kg/m2 (range, 16-37). Thirty-five patients (43.8 %) had previous surgery. A median operative time of 82.5 (range, 40-190) minutes and a median estimated blood loss of 50 (50-500) mL were registered. We observed 1 (1.3 %) intraoperative complication. The median time to discharge was 1 (range, 1-5) day. Patients were extremely satisfied with the scar evaluation and postoperative pain control. Five (6.25 %) complications were recorded within 30 days after surgery. CONCLUSION: Percutaneous-assisted technique for extrafascial hysterectomy achieved excellent results in terms of feasibility, safety, and efficacy, even in complex cases and advanced surgical procedures. Therefore, the technique appears to balance the limitations and advantages of minimal surgical invasiveness and standard approach efficacy.
