Purpose: Placement of a drain during robotic assisted partial nephrectomy (RAPN) and robotic assisted radical prostatectomy (RARP) is standard practice for many urologists and can aid in assessment and management of complications such as urine leak, lymphocele, or bleeding. However, drain placement can cause discomfort and delay patient discharge, with questionable benefit. We aim to assess the correlation between drain placement with post operative complications. Methods: The NSQIP targeted database was queried for patients who underwent RAPN or RARP from 2019 to 2021. Our primary outcomes included 30-day complication rates stratified by intraoperative drain placement. Secondary outcomes included procedure-specific complications, length of stay (LOS), and readmissions. Multivariable regression analyses, with Bonferroni correction, were performed for each post-operative complication. Results: We identified 4738 and 13,948 patients who underwent RAPN and RARP, respectively. Drains were not placed in 2258 (47.7%) and 6700 (48%) patients, respectively. On adjusted multivariable analysis in the RAPN cohort, omission of drain placement was associated with decreased LOS (β -0.45; 99.58% CI [-0.59, -0.32]) but no difference in overall complication rates. After adjusted analysis in the RARP cohort, omission of drain placement was associated with decreased risk of any complication (OR 0.73 [0.62–0.87]), infectious complication (OR 0.66 [0.49–0.89]), and LOS (β -0.30 [-0.37, -0.24]). Conclusions: Using a large contemporary database, this study demonstrates that omission of drains during RAPN and RARP was safe without increased risk of postoperative complications. Despite inherent selection bias in this cohort, our data suggests that routine drain placement is not necessary for these procedures. Highlights: Foregoing drains can be safe in select patients undergoing robotic prostatectomy and partial nephrectomy. Foregoing drain placement did not increase the risk of overall complications or readmission. Drain placement was associated with increased hospital length of stay. [ABSTRACT FROM AUTHOR]

Background: We detail our approach and experience with a hybrid version of the endopelvic hood-sparing (HS) robot-assisted radical prostatectomy (RARP) using the da Vinci robotic platform. Materials and Methods: We retrospectively reviewed the records of 200 patients who underwent RARP by a single surgeon. Patients were propensity-matched into three cohorts depending on biopsy and prostatectomy Gleason Grade Groups: traditional retropubic (RP) (n = 80), retzius-sparing (RS) (n = 40), and HS (n = 80). Patient characteristics and oncologic and functional outcomes were examined. Zero pads per day defined return of continence. Erections suitable for penetrative intercourse with/without medications defined return of sexual function. Results: Patient characteristics were similar between cohorts excluding prostate-specific antigen levels (p = 0.014), which were significantly lower in the RS cohort (7.1 ± 5.3 ng/mL) compared with RP (9.2 ± 9.3 ng/mL) and HS (8.8 ± 8.9 ng/mL). Clinically significant positive margin rates were significantly higher (p = 0.046) in the RS cohort (32.5%) compared with RP (17.5%) and HS (13.9%). Biochemical recurrence and metastasis rates were similar between all cohorts. Median time to continence was significantly lower for RS and HS-RARP (p < 0.001) compared with RP-RARP at 1.3, 1.6, and 5.4 months, respectively. Median time to return of sexual function was significantly lower for RS and HS-RARP (p < 0.001) compared with RP-RARP at 4.0, 7.7, and 15.1 months, respectively. Conclusions: Our hybrid HS-RARP approach provides functional outcomes similar to RS-RARP with the early oncologic control of traditional RP-RARP. [ABSTRACT FROM AUTHOR]

Background/Objectives: The presence of seminal vesicle invasion (SVI) in prostate cancer (PCa) is associated with poorer postoperative outcomes. This study evaluates the predictive value of magnetic resonance imaging (MRI) and prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) for SVI in PCa. Methods: This cohort study included consecutive robotic prostatectomy patients for PCa at three Australian tertiary referral centres between April 2016 and September 2022. MRI and PSMA PET/CT results, clinicopathological variables, including age, BMI, prostate-specific antigen (PSA), PSA density, DRE, Biopsy Gleason score, Positive biopsy cores, PIRADS v2.1 score, MRI volume and MRI lesion size were extracted. The sensitivity, specificity, and accuracy of MRI and PSMA PET/CT for predicting SVI were compared with the histopathological results by receiver operating characteristic (ROC) analysis. Subgroup univariate and multivariate analysis was performed. Results: Of the 528 patients identified, 86 had SVI on final pathology. MRI had a low sensitivity of 0.162 (95% CI: 0.088–0.261) and a high specificity of 0.963 (95% CI: 0.940–0.979). The PSMA PET/CT had a low sensitivity of 0.439 (95% CI: 0.294–0591) and a high specificity of 0.933 (95% CI: 0.849–0.969). When MRI and PSMA PET/CT were used in combination, the sensitivity and specificity improved to 0.514 (95%CI: 0.356–0.670) and 0.880 (95% CI: 0.813–0.931). The multivariate regression showed a higher biopsy Gleason score (p = 0.033), higher PSA (p < 0.001), older age (p = 0.001), and right base lesions (p = 0.003) to be predictors of SVI. Conclusions: MRI and PSMA PET/CT independently underpredicted SVI. The sensitivity and AUC improved when they were used in combination. Multiple clinicopathological factors were associated with SVI on multivariate regression and predictive models incorporating this information may improve oncological outcomes. [ABSTRACT FROM AUTHOR]

In the present study, we aimed to systematically evaluate the current evidence regarding the intraoperative workload of surgeons performing robot-assisted radical prostatectomy (RARP) for prostate cancer. A systematic search was carried out in the PubMed-MEDLINE and Web of Science databases through April 2024 using the following search terms: "workload AND robot assisted radical prostatectomy", "workload AND robotic radical prostatectomy", "task load AND robotic radical prostatectomy", "task load AND robot assisted radical prostatectomy" and "NASA-TLX AND robot assisted radical prostatectomy" by combining population, intervention, comparison, and outcome (PICO) terms, following preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. We therefore selected studies that included patients with prostate cancer (P) who underwent robotic radical prostatectomy (I) and reported a workload/task load questionnaire (C) to assess the intraoperative workload/task load of the surgeon performing robot-assisted radical prostatectomy (O). A total of 11 studies were identified. The surgeon's workload during RARP was assessed using the National Aeronautics and Space Administration task load index (NASA-TLX) and/or the surgery task load index (SURG-TLX) in the studies. Total NASA-TLX scores of the studies ranged from 22.7 ± 3.2 to 62.0 ± 6.4. Mental and physical demands, flow interruptions, surgeon experience, the use of single or multiple ports, and the relationship between the surgeon and other staff in the operating theater may play a role in the intraoperative workload of the console surgeon. The studies we reviewed suggest that RARP offers an acceptable workload for the console surgeon despite its mental demands. [ABSTRACT FROM AUTHOR]

Prostate cancer is the second most common cancer among men, with many treatment modalities available for patients, such as radical prostatectomy, external beam radiotherapy, brachytherapy, high-intensity focused ultrasound, cryotherapy, electroporation and other whole-gland or focal ablative novel techniques. Unfortunately, up to 60% of men with prostate cancer experience recurrence at 5 to 10 years. Salvage radical prostatectomy can be offered as an option in the setting of recurrence after a primary non-surgical treatment. However, the complexity of salvage radical prostatectomy is considered to be greater than that of primary surgery, making it the least popular treatment of choice. With the wide use of robotic platforms in urologic oncologic surgery, salvage radical prostatectomy has attracted attention again because, compared to past data, modern series involving salvage Robot-Assisted Radical Prostatectomy have shown promising results. In this narrative literature review, we comprehensively examined data on salvage radical prostatectomy. We investigated the correlation between the different types of primary prostate cancer therapy and the following salvage radical prostatectomy. Furthermore, we explored the concept of a robotic approach and its beneficial effect in salvage surgery. Lastly, we emphasized several promising avenues for future research in this field.

Definitive surgical treatment for prostate cancer continues to evolve with robotic prostatectomy being the preferred technique. This technique has led to decreased blood loss and transfusion rates. Although uncommon, this case report presents a rare incident of delayed inferior epigastric bleed from a port site after a robotic prostatectomy. Our case report aims to establish the first known algorithm to address port site bleeding after robotic prostatectomies. Having an established algorithmic approach to evaluate and treat patients with postoperative port site bleeding is paramount. Using the algorithm, this patient was stabilized, and bleeding was controlled with embolization.

Introduction: Retzius-sparing prostatectomy was promoted with the early continence result. The long-term oncologic outcome is still unknown. In this study, we aimed to compare the intermediate-term oncologic outcomes of these two approaches in patients' cohort who were treated as part of a randomized controlled trial. Methods: A total of 120 patients were previously randomized equally to receive Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RS-RARP) vs standard robot-assisted laparoscopic radical prostatectomy (S-RARP) between January 2015 and April 2016. Baseline, surgical, and pathologic characteristics as well as oncologic outcomes were assessed. The analysis was done based on the treatment received. Result: Sixty-three patients underwent S-RARP, whereas 57 patients underwent RS-RARP. There was no statistically significant difference in the baseline nor surgical characteristics. The median follow-up was 71.24 (interquartile range: 59.75–75.75) months. There were more pathologic T3 diseases in RS-RARP. There was no significant difference in the positive margin status nor in the biochemical recurrence (BCR) rate among both groups. After S-RARP and RS-RARP, 6 and 10 patients had BCR, and the 5 years BCR-free survival was 91% and 85%, respectively (p = 0.21). Conclusion: In this cohort, there was no difference in BCR in the patients who received either technique. Further multi-institutional studies with a larger sample size and longer follow-up are required. [ABSTRACT FROM AUTHOR]

Objective: The objective was to investigate the current evidence and discern urinary continence rates post robot-assisted laparoscopic radical prostatectomy (RALP). Methods: A systematic review of the literature was carried out, searching the Embase, Scopus and PubMed databases between 1 January 2000 and 1 May 2020. The search terms "Robotic prostatectomy AND continence" were employed. Articles were selected in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Statistical analysis was performed using the programme R; cumulative analysis of percentage of men continent was calculated. Results: A total of 3101 abstracts and 50 full text articles were assessed, with 22 publications included (n = 2813 patients). There were 21 randomised controlled trials and one partly randomised controlled trial with four publications comparing RALP to other prostate cancer treatments. Thirteen studies explored different RALP techniques, and five studies examined vesicourethral anastomosis (VUA). There were statistically significant improvements in early urinary continence rates in three studies analysing reconstructive techniques (83% vs 60%, p = 0.04; 26.5% vs 15.4%, p = 0.016; 77% vs 44.1%, p ≤ 0.001). Long-term continence rates were not significantly improved across all studies assessing reconstruction. One study comparing RALP vs laparoscopic radical prostatectomy (LRP) demonstrated a statistically significant improvement in continence at 3 months (80% vs 73.3%, p < 0.001); 6 months (83.3% vs 81.4%, p < 0.001); 12 months (95% vs 83.3%, p < 0.001) and 24 months (96.7% vs 85%, p < 0.001). Early continence was less favourable for RALP when compared to brachytherapy (BT) patients at 3 months (86% vs 98.7%, p < 0.05) and 6 months (90.5% vs 98.7%, p < 0.05). Conclusion: Early continence rates were improved across numerous techniques in RALP. These results were not translated into significantly improved long-term outcomes. Continence rates following RALP were favourable compared to LRP, similar to ORP and less favourable compared to BT. Our findings suggest that post-RALP continence can be further improved with alterations in robotic technique. [ABSTRACT FROM AUTHOR]

Objectives: Robotic radical prostatectomy (RARP) is a well-established treatment for localised prostate adenocarcinoma. The benefits of this minimally invasive technique include shortened operative time and improved patient recovery. However, the development of inguinal hernia (IH) before, during, and following RARP has been reported. The aim of this study is to evaluate the incidence, management, and recurrence of IHs in patients undergoing RARP for prostate cancer. Methods: A literature search was conducted using the PubMed database from August 2007 to October 2020 using the keywords 'robotic prostatectomy' and 'inguinal hernia'. Studies evaluating the incidence and recurrence of IH in patients undergoing RARP were identified and included. The initial search identified 77 articles. After excluding one duplicate, six case reports, three editorial comments, four articles not in English, eight review articles, and 14 studies that did not mention hernia incidence, 41 studies were included in our final literature review. Results: Concomitant IH repair (IHR) during RARP resulted in decreased symptomatic hernia recurrence during the follow-up period. When compared to patients who had not undergone hernia repair, the patients who underwent IHR during RARP did not experience greater complications in the postoperative period. Conclusions: Patients that undergo an intraoperative IHR during RARP did not experience significant adverse postoperative complications. Although operative time can slightly increase compared to RARP alone, we recommend a thorough preoperative physical examination in all patients scheduled to undergo RARP to evaluate for IH in addition to a thorough discussion with the patient of the risks and benefits of intraoperative repair. Level of evidence: Not applicable [ABSTRACT FROM AUTHOR]

In this study, we assess the impact of frailty on the success rate and risk of complications of robot-assisted urological procedures and introduce effective preoperative screening tools to evaluate frail patients' fitness to tolerate robot-assisted urological surgery. We performed a search of electronic databases for available studies, published up to August 2023, investigating the outcomes of robot-assisted urological oncology procedures and their safety in frail patients. Sixteen studies were ultimately selected, investigating the implications of frailty in robot-assisted radical cystectomy, robotassisted partial nephrectomy, and robot-assisted radical prostatectomy. All the studies used the Clavien-Dindo classification of complications with serious complications considered as Clavien-Dindo =3. Frail patients significantly benefit from robot-assisted urological procedures in comparison to open surgery, with lower rates of blood transfusion and a shorter length of stay. However, they also have a higher risk of postoperative complications than non-frail patients, as well as increased rates of conversion to open, total hospital costs, and in-hospital mortality after robot-assisted procedures. Robot-assisted urological procedures can improve the postoperative recovery of frail patients in comparison to open surgery. Reliable frailty indexes such as the Johns Hopkins indicator and simplified frailty index, as well as the Geriatric 8 screening tool, should be routinely used in the preoperative assessment of frail patients to optimize surgical decision-making.

Objectives: To assess the ChatGPT (Open AI) artificial intelligence platform's utility and accuracy as a patient education tool in robotic-assisted radical prostatectomy. Materials and methods: The ChatGPT 3.5 interface (https://chat.openai.com/chat) was interrogated and asked the 14 questions related to the frequency of complications of robotic-assisted radical prostatectomy as listed on British Association of Urological Surgeons (BAUS) patient information leaflet "Robotic-Assisted Laparoscopic Radical Prostatectomy)" published July 2021. The AI's responses to each question were tabulated, and compared alongside the official figures quoted from the BAUS information leaflet. A global assessment of the AI's response was also made for accuracy and relevance to patients. Results: Of the 14 questions asked, 11/14 (78.6%) of ChatGPT's quoted figures were considered concordant and comparable to those quoted by the BAUS patient information leaflet. 13/14 (92.9%) of ChatGPT's responses were globally assessed to contain accurate information, appropriate, and pertinent to a patient's potential enquiry. Conclusion: ChatGPT is a powerful tool and is able to generate accurate and helpful information for patients seeking information regarding urological procedures and their potential complications. It is not, however, infallible, and urologists should remain vigilant in their patient interactions to any potential misinformation a patient may have gathered from it in their personal research prior to surgery.

New imaging technologies play a pivotal role in the current management of patients with prostate cancer. Robotic assisted radical prostatectomy (RARP) is a standard of care for localized disease and through the already imaging-based console subject of research towards combinations of imaging technologies and RARP as well as their impact on surgical outcomes. Therefore, we aimed to provide a comprehensive analysis of the currently available literature for new imaging technologies for RARP. On 24 January 2023, we performed a systematic review of the current literature on Pubmed, Scopus and Web of Science according to the PRISMA guidelines and Oxford levels of evidence. A total of 46 studies were identified of which 19 studies focus on imaging of the primary tumor, 12 studies on the intraoperative tumor detection of lymph nodes and 15 studies on the training of surgeons. While the feasibility of combined approaches using new imaging technologies including MRI, PSMA-PET CT or intraoperatively applied radioactive and fluorescent dyes has been demonstrated, the prospective confirmation of improvements in surgical outcomes is currently ongoing.

ObjectiveTo explore the incidence of and potential risk factors for acute urine retention (AUR) after robot-assisted radical prostatectomy (RARP) and its effect on early urine continence.MethodsA retrospective analysis of patients who underwent RARP by a single surgeon between July 2016 and June 2017 was performed to assess the incidence of AUR and its effect on early continence. Continence was assessed through self-reported questionnaires completed approximately three months after surgery. Early urine continence was defined as using zero pads per day at the time of the three-month follow-up. Descriptive statistics and logistic regression analysis were used to assess independent predictor of AUR.ResultsOf 379 patients, 19 (5%) developed AUR after RARP. No significant difference in baseline characteristics between those who developed AUR post-RARP and those who did not. There was no statistically significant difference in the reported early continence and number of pads used per day between patients with AUR and patients without AUR (31.6% vs. 23.1%, P = 0.39), (1.6 vs. 1.4, P = 0.913), respectively.ConclusionAUR post-RARP is an infrequent postoperative complication with no impact on early continence rate. No patient-related factors were associated with the development of AUR.

Background: Robot-assisted radical prostatectomy (RARP) has been a treatment for men who suffer from intermediated to high-risk prostate cancer in Australia since 2003. The primary outcomes in relation to learning curves in robotic surgery have been extensively researched in overseas populations, but there is no study from a cohort of Australian surgeons performing RARP. This study aims to highlight the effect of RARP learning curves on primary surgical outcomes in a high-volume Australian centre. Methods: A retrospective audit of all RARP performed at Epworth Healthcare from 2016 to 2021 was performed. The primary outcome data collected included operating time (OT), estimated blood loss (EBL), and positive surgical margins (PSM). Exclusion criteria were applied. Positive outcomes were set at OT 240 min, blood loss 310 mL, and negative surgical margins. Results: A total of 3969 cases were analysed for a cohort of 53 surgeons. Of these surgeons, 24 surgeons have performed >50 operations to be able to undergo learning curve analysis. The median OT was 229 min, the median blood loss was 353 mL, and most cases had negative surgical margins (>1 mm, n = 3681, 92.7%). The mean learning curve transition point was 65 cases. There was a significant difference in the EBL and rate of PSM for the higher volume cohort (p = 0.002 and

Post-prostatectomy Urinary incontinence (PPUI) due to open or robotic surgery has a negative impact on patients' psycho-social well-being and leads to altered quality of life (Kielb and Dunn in J Urol 166:958–61, 2001). Sphincteric incompetence overall remains the primary cause of PPUI, and it is believed that direct damage and manipulation intraoperatively could be the probable causes [1] (Bayoud et al. in Int J Urol 22:283–7-10, 2015). Pelvic floor muscle (PFM) rehabilitation appears to be beneficial in hastening the return of continence (Kampen and Poppel in Lancet 355:98–102, 2000). Hence, there is a need to re-educate or strengthen the pelvic floor muscles. To study the return of continence, and time duration required for the pelvic floor muscles to regain strength and endurance, thereby, leading to urinary continence and its effect on the quality of life of patients who have undergone robotic prostatectomy. Pelvic floor muscle grading, a 24 h pad test, and an International Prostate symptom scoring (IPSS) were the outcome measures used to assess the effect on incontinence status post-operatively. 69 patients were screened between a duration of 3 years, i.e., 2017–2020. Four patients remained incontinent 3 months post-surgery. On the contrary, 65 patients regained continence. There is a definitive effect of early Kegel's exercise, the patient gains good pelvic floor muscle strength, portraying a reduction in dribbling or leakage of urine. Also, there is an improvement in the quality of life after Robotic Prostatectomy in Prostate cancer patients after 6 weeks of surgery. 94.20% of the patients have shown a have gained continence by 3 months post-robotic prostatectomy following a regular exercise regime of Kegel's exercise.

Learning physiological responses through clinical application provides a meaningful experience that engraves itself in one's mind forever. Robotic prostatectomy requires a patient to be positioned in a steep Trendelenburg, and this is associated with many physiological responses that involve the cardiovascular, respiratory, and central nervous system. Understanding the physiological responses during the robotic prostatectomy provides vital intraoperative monitoring and ensures the patient's safety. [ABSTRACT FROM AUTHOR]

Introduction:To evaluate the effect of valveless trocar system (VTS) on intra-operative parameters, peri-operative outcomes, and 30-day postoperative complications in patients undergoing robotic-assisted laparoscopic prostatectomy. Methods:A total of 200 consecutive patients undergoing Robot-assisted radical prostatectomy by a single surgeon were prospectively evaluated using either the valveless trocar (n = 100) or standard trocars (n = 100). Patient demographics, intra-operative parameters, length of stay, presence or absence of postoperative nausea and vomiting, analog pain score at 0-6 hours, 6-12 hours, 12-18 hours, and >24 hours, and 30-day postoperative complications were analyzed. Results:There were no significant differences in estimated blood loss, intra-operative urine output, length of stay, or 30-day complication rates between the two groups. While the VTS group had higher Body Mass Index (BMI) (28.45 vs. 27.23; P = 0.049), the operative time was significantly shorter in the VTS group (146 minutes vs. 167 minutes; P < .005). The VTS group experienced fewer episodes of nausea (2% vs. 10%; P = 0.0172). The VTS group had less pain intensity compared to the control in the first 18 hours: 0-6 hours (1.9 vs. 2.5; P = 0.034), 6-12 hours (2.8 vs. 3.6; P = 0.044), and 12-18 hours (2.2 vs. 3.1; P = 0.049), respectively. Conclusion:The use of a valveless trocar system during robot-assisted robotic prostatectomy may shorten operative times, and reduce postoperative pain scores and nausea episodes without increasing the 30-day complication rate. Further prospective randomized trials should be performed to validate these findings.

Background. Appearance of new surgical techniques are aimed to improve not only oncological, but also functional outcomes of radical prostatectomy. A good urinary continence after radical surgical treatment remains an important aspect with not only medical but also social significance, since it can significantly reduce the patient’s quality of life.Aim. To describe a new surgical technique of lateral fixation of the bladder neck using autotissue during robotic- assisted radical prostatectomy, to evaluate its effecacy and safety.Materials and methods. From February till November 2020, 20 patients with localized prostate cancer underwent radical robot-assisted prostatectomy. All operations were performed in one medical center, by one experienced robotic surgeon (more than 1000 operations). After the imposition of vesicourethral anastomosis the reconstruction of pelvis was performed by lateral fixation of the vesical cervix with auto-tissue flaps of the intrapelvic fascia. A prerequisite was the preservation of the puboprostatic ligaments, endopelvic fascia and puboperineal muscles. The duration of the operation (console time and time of reconstruction), the volume of intraoperative blood loss, perioperative complications according to Clavien–Dindo, the duration of urethral catheter and the patient’s length of hospital stay, oncological results (pT stage, presence/absence of a surgical margin), the presence of immediate continence, as well as continence 3 months postoperatively were assessed.Results. The mean operative time was 142 (115–168) minutes, mean console time – 64 (50–98) minutes. The mean duration of lateral fixation stage was 3,5 (2–5,5) minutes. Urethral catheter was removed at 7th day postoperatively. There were no Clavien–Dindo group III–V complications registered. Immediate continence rate – 75 % (15 patients), early continence rate – 25 % (5 patients).Conclusion. The use of a new technique of lateral reconstruction during robotic-assisted radical prostatectomy using endopelvic fascia flaps is safe and effective, it improves functional outcomes without affecting oncological results.

Abstract Background Robotic radical prostatectomy (RARP) is a first-line curative treatment option for localized prostate cancer. Postoperative erectile dysfunction and urinary incontinence are common associated adverse side effects that can negatively impact patients’ quality of life. Preserving the lateral neurovascular bundles (NS) during RARP improves functional outcomes. However, selecting men for NS may be difficult when there is concern about incurring in positive surgical margin (PSM) which in turn risks adverse oncological outcomes. The NeuroSAFE technique (intra-operative frozen section examination of the neurovascular structure adjacent prostate margin) can provide real-time pathological consult to promote optimal NS whilst avoiding PSM. Methods NeuroSAFE PROOF is a single-blinded, multi-centre, randomised controlled trial (RCT) in which men are randomly allocated 1:1 to either NeuroSAFE RARP or standard RARP. Men electing for RARP as primary treatment, who are continent and have good baseline erectile function (EF), defined by International Index of Erectile Function (IIEF-5) score > 21, are eligible. NS in the intervention arm is guided by the NeuroSAFE technique. NS in the standard arm is based on standard of care, i.e. a pre-operative image-based planning meeting, patient-specific clinical information, and digital rectal examination. The primary outcome is assessment of EF at 12 months. The primary endpoint is the proportion of men who achieve IIEF-5 score ≥ 21. A sample size of 404 was calculated to give a power of 90% to detect a difference of 14% between groups based on a feasibility study. Oncological outcomes are continuously monitored by an independent Data Monitoring Committee. Key secondary outcomes include urinary continence at 3 months assessed by the international consultation on incontinence questionnaire, rate of biochemical recurrence, EF recovery at 24 months, and difference in quality of life. Discussion NeuroSAFE PROOF is the first RCT of intra-operative frozen section during radical prostatectomy in the world. It is properly powered to evaluate a difference in the recovery of EF for men undergoing RARP assessed by patient-reported outcome measures. It will provide evidence to guide the use of the NeuroSAFE technique around the world. Trial registration NCT03317990 (23 October 2017). Regional Ethics Committee; reference 17/LO/1978.

A radical prostatectomy is frequently used as the first-line treatment for men with prostate cancer. Persistent urinary incontinence after surgery is one of the most severe adverse events. We report the results of a comprehensive literature search focused on post-prostatectomy urinary incontinence (PPI), performed by a panel of experts on non-neurogenic lower urinary tract symptoms. The data on the prevalence and timing of PPI are very heterogeneous. The etiology of PPI can be multifactorial and mainly dependent on patient characteristics, lower urinary tract function or surgical issues. The medical history with a physical examination, the use of validated questionnaires with a voiding diary and pad tests are determinants in identifying the contributing factors and choosing the right treatment. Lifestyle intervention and urinary containment are the most frequently used strategies for the conservative management of PPI, while antimuscarinics, beta-3 agonists and duloxetine (off-label) are drugs indicated to manage PPI with a concomitant overactive bladder. Surgical therapies for the management of post-prostatectomy SUI include non-adjustable trans-obturator slings in men with mild-to-moderate incontinence and an artificial urinary sphincter in men with moderate-to-severe incontinence.

Objectives: To prospectively analyse robotically administered transperitoneal transversus abdominis plane (robot‐assisted transversus abdominis plane [RTAP]) compared with both ultrasonography‐guided transversus abdominis plane (UTAP) and local anaesthesia (LA) with regard to pain control and narcotic use in patients undergoing robot‐assisted prostatectomy (RARP) or robot‐assisted partial nephrectomy (RAPN). Subjects/Patients and Methods: Patients undergoing RARP or RAPN were randomized in a single‐blind 2:2:1 fashion to RTAP:UTAP:LA, with the study powered to evaluate superiority of UTAP to LA and non‐inferiority of RTAP to UTAP. We compared time to deliver the block, operating room time, postoperative pain scores using the visual analogue scale, and intra‐operative and postoperative analgesia consumption. Results: A total of 143 patients were randomized and received treatment. There was no significant difference in patient baseline characteristics. UTAP did not demonstrate superiority to LA in terms of pain control. RTAP and LA were faster to administer than UTAP (time to perform block 2.5 vs 2.5 vs 6.25 min; P < 0.001). There was no difference in postoperative narcotic, acetaminophen, ketorolac or ondansetron requirements among the three groups (P > 0.05). The study was terminated early due to the unexpected efficacy of LA. Conclusion: This study showed that UTAP and RTAP do not provide superior pain control to LA. The efficiency, effectiveness, and ease of administration of LA make it an excellent option for first‐line therapy for postoperative analgesia. [ABSTRACT FROM AUTHOR]

Purpose: Robotic prostatectomy is the most common surgical approach for treating prostate cancer. Patients undergoing robotic prostatectomy may have bullae, which may rupture leading to pneumothorax. We evaluated the incidence of pneumothorax due to preoperative bullae rupture in robotic prostatectomy. Methods: A large retrospective study of patients who underwent robotic prostatectomy between 2009 and 2021 was conducted. Bullae were detected using chest computed tomography. Pneumothorax was detected using a chest X-ray. The primary outcome was the incidence of pneumothorax due to bullae rupture. Secondary outcomes were the prevalence of preoperative bullae and the evaluation of postoperative outcomes, including length of hospital stay, intensive care unit admission rate, and prolonged intensive care unit stay (> 2 days). Results: A total of 6605 patients were included. The prevalence of preoperative bullae was 3.0% (196/6,605). There was no incidence of pneumothorax due to bullae rupture. No significant difference in the incidences of pneumothorax between patients with and without bullae (0/196 vs. 2/6,409, P > 0.999) was observed. In addition, length of hospital stay, intensive care unit admission rate, and prolonged intensive care unit stay were not significantly different between the two groups. Kaplan–Meier analysis showed that there was no significant difference in lengths of hospital stay between the two groups (log-rank test, P > 0.999). Conclusion: In our cohort, there was no incidence of pneumothorax following robotic prostatectomy in patients with preoperative bullae. This result could help in the management of patients with prostate cancer with bullae. [ABSTRACT FROM AUTHOR]

Robot-assisted radical prostatectomy (RARP) is the most adopted treatment for localized prostate cancer. The aim of this study was to explore the learning curves (LC) for overall and site-specific positive surgical margins (PSM) occurrence after RARP of multiple surgeons within a step-structured mentor-initiated training program. The study included consecutive patients undergoing RARP between January 2013 and March 2020, by three surgeons: a mentor and his two trainees. Prospectively collected patients' data were retrospectively analyzed. The cumulative summation (CUSUM) method was used to generate the LCs, with turning points indicating the number of cases to reach proficiency levels. Furthermore, the association between PSM and surgical experience was evaluated, adjusting for case mix. A total of 761 consecutive patients were included, 370 treated by the Mentor surgeon, 247 and 144 treated, respectively, by the two Trainees. Mentor and Trainees had similar PSM rates (31.6% vs 28.0% vs 31.3%, p = 0.6). CUSUM charts showed different LC shapes for different PSM locations (postero-lateral, bladder neck, apex, and multifocal/> 3 mm). Surgical experience was significantly associated with overall, postero-lateral, and multifocal/> 3 mm PSMs, in the Mentor series only. Trainees reached their turning points after far fewer cases then the Mentor, both for overall (12 and 31 vs 153), postero-lateral (24 and 30 vs 120), and multifocal/> 3 mm PSMs (9 and 31 vs 153). The achievement of stable SM proficiency takes involved different LCs depending on the prostatic location being considered. Monitoring site-specific LC can indicate the surgical steps for which there may be still room for further technical refinements, even when an apparent proficiency status seems achieved.

Background: To date, robotic surgery in urology is well established all over the world. The newest platform on the market is the HUGO™ RAS system, developed by Medtronic. In this paper we provide a brief description of the system and describe our system set-up and surgical approach with this new platform in our initial experience of robotic radical prostatectomy (RARP) series. Materials and methods: After an official training, seven consecutive patients affected by localized prostate cancer underwent RARP with HUGOTM RAS system at our Institution. A description of our surgical approach and docking setup is provided. Docking and console times were reported for all precedures together with main suggestions to facilitate the use of this new system at the beginning of the experience. Results: Our operating room setup has shown to be safe, effective, and easy replicable. During our series, operative times appeared to be easy reproducible and comparable to those obtained with daVinci system. No major system faults and conflicts between robotic arms were observed after the first procedure. Conclusions: Our surgical approach and system configuration for performing RARP with the new HUGO™ RAS system appears to be safe, efficient and easy reproducible. [ABSTRACT FROM AUTHOR]

Robotic-assisted laparoscopic radical prostatectomy (RALP) is the gold standard surgical approach for treatment of prostate cancer. Prostate cancer is often comorbid with erectile dysfunction (ED), and a small subgroup of men undergoing RALP have an indwelling inflatable penile prosthesis (IPP). In men with IPPs, we perform two techniques at the time of RALP to preserve the pelvic reservoir. In the No Touch Technique, we leave the pseudocapsule of the reservoir intact, electing to dissect the pelvic sidewall and lateral prostatic attachments away from the pseudocapsule. In the Safe Mobilization Technique, we sharply open the pseudocapsule overlying the reservoir and relocate the reservoir out of the pelvis. We retrospectively analyzed 155 cases (Group IPP) from a cohort of 1000 men who underwent RALP. These cases were compared to a randomly selected control group comprising 455 men with PCa who underwent RALP without prior IPP placement (Group NoIPP). We compared perioperative and functional outcomes. The overall incidence of positive surgical margins (PSM) did not significantly differ between the groups (14% in Group IPP and 12% in Group NoIPP, p = 0.4). Furthermore, there was no statistically significant difference in the incidence of PSM at the bladder neck between Group IPP (5.3%) and Group NoIPP (3.4%), p = 0.1. Binomial logistic regression analysis did not find prior IPP placement to be a significant predictor of continence at 3 and 6 months or for BCR. All patients in Group IPP were able to successfully cycle their devices postoperatively and there were no reported device infections. The No Touch Technique and Safe Mobilization Technique are easy to perform and safe adjunct procedures at the time of RALP in men with pre-existing IPP., Competing Interests: Declarations.

Definitive surgical treatment for prostate cancer continues to evolve with robotic prostatectomy being the preferred technique. This technique has led to decreased blood loss and transfusion rates. Although uncommon, this case report presents a rare incident of delayed inferior epigastric bleed from a port site after a robotic prostatectomy. Our case report aims to establish the first known algorithm to address port site bleeding after robotic prostatectomies. Having an established algorithmic approach to evaluate and treat patients with postoperative port site bleeding is paramount. Using the algorithm, this patient was stabilized, and bleeding was controlled with embolization., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this article., (© 2024 The Authors.)

Objective: Surgical training has digitally evolved in recent years owing to technological advancements such as the implementation of tele-mentoring. Tele-mentoring enables resident surgeons to receive instruction and guidance from experts remotely, given a suitable internet connection. It is hypothesised that this augmented reality (AR) enhances the learning experience and surgical performance, by the use of overlays to live streamed surgery. Patient and surgical procedure: This study evaluated the implementation of a novel AR platform for robot assisted radical prostatectomy (RARP) procedures, assessing participant opinions, efficacy, and safety through questionnaires. Additionally, we investigated the broader utility of surgical recording in a video labelling study. All ethical protocols and patient confidentiality was maintained during this study. Results: This preliminary research demonstrates favourable results on average for ease of use, audio, and video quality rated by both mentors and mentees (Above 4 out of 5 in all fields). Questionnaire fields assessing future uses in mentees, revealed that ‘mentoring for technically challenging cases’ and ‘assessment or revalidation of surgeons’ were useful. The use of RARP recordings for video labelling yielded high success in a novice student. Among 25 video recordings, the labelled video selected for assessment showed an accuracy score averaging 93.1% with a range of 85.6% - 100% across expert examiners. Conclusion: The use of an AR telementoring platform can assist in building competency safely in advanced level surgical trainees for RARP. The self-training of a novice student in the accurate segmentation of RARP video recording confirmed a high degree of accuracy is feasible. Further research across numerous surgical procedures with a cohort of students is mandated.

Background: We performed a retrospective comparison of surgical, oncologic, and functional outcomes after robot-assisted radical prostatectomy between patients who have undergone prior transurethral resection of prostate (TURP) to TURP-naive patients. Methods: Past robotic prostatectomy hospital data were scrutinized to form two matched groups of patients: those who have undergone prior TURP and TURP-naive patients. The perioperative and pathologic data along with functional and oncologic outcomes for a period of 3 years were compared between groups. Results: Compared with TURP-naive patients, prior TURP patients experienced longer robot-assisted laparoscopic prostatectomy times (p < 0.001), increased incidence of bladder neck reconstruction (p = 0.03), greater blood loss (p = 0.0001), and lesser nerve sparing (p < 0.01). Complication rates (p = 0.3), positive surgical margin (p = 0.4), extracapsular disease (p = 0.3), or seminal vesicle invasion (p = 0.1) were comparable between groups. Continence (p = 0.5) and potency (p = 0.1) at 1 year were not different between groups. Biochemical recurrence rates were not different at 3 years (p = 0.9). Diabetes slowed recovery of continence in patients with prior TURP compared with TURP-naive patients until 6 months after surgery. Conclusion: Although prior TURP makes subsequent robotic prostatectomy more technically demanding, it can be safely performed by experienced surgeons without compromising long-term functional or oncologic outcomes.

Background: Robotic radical prostatectomy (RARP) is a first-line curative treatment option for localized prostate cancer. Postoperative erectile dysfunction and urinary incontinence are common associated adverse side effects that can negatively impact patients' quality of life. Preserving the lateral neurovascular bundles (NS) during RARP improves functional outcomes. However, selecting men for NS may be difficult when there is concern about incurring in positive surgical margin (PSM) which in turn risks adverse oncological outcomes. The NeuroSAFE technique (intra-operative frozen section examination of the neurovascular structure adjacent prostate margin) can provide real-time pathological consult to promote optimal NS whilst avoiding PSM.Methods: NeuroSAFE PROOF is a single-blinded, multi-centre, randomised controlled trial (RCT) in which men are randomly allocated 1:1 to either NeuroSAFE RARP or standard RARP. Men electing for RARP as primary treatment, who are continent and have good baseline erectile function (EF), defined by International Index of Erectile Function (IIEF-5) score > 21, are eligible. NS in the intervention arm is guided by the NeuroSAFE technique. NS in the standard arm is based on standard of care, i.e. a pre-operative image-based planning meeting, patient-specific clinical information, and digital rectal examination. The primary outcome is assessment of EF at 12 months. The primary endpoint is the proportion of men who achieve IIEF-5 score ≥ 21. A sample size of 404 was calculated to give a power of 90% to detect a difference of 14% between groups based on a feasibility study. Oncological outcomes are continuously monitored by an independent Data Monitoring Committee. Key secondary outcomes include urinary continence at 3 months assessed by the international consultation on incontinence questionnaire, rate of biochemical recurrence, EF recovery at 24 months, and difference in quality of life.Discussion: NeuroSAFE PROOF is the first RCT of intra-operative frozen section during radical prostatectomy in the world. It is properly powered to evaluate a difference in the recovery of EF for men undergoing RARP assessed by patient-reported outcome measures. It will provide evidence to guide the use of the NeuroSAFE technique around the world.Trial Registration: NCT03317990 (23 October 2017). Regional Ethics Committee; reference 17/LO/1978.

PurposeTo compare the recovery of erections and potency following the transection of accessory pudendal arteries (APAs) in men undergoing robot-assisted radical prostatectomy (RARP) compared with men with normal vascular anatomy.Materials and methodsA total of 880 consecutive patients who underwent RARP from January 1, 2007 to December 31, 2014 were included with prospectively collected data in cross-sectional analysis. Erectile function (EF) was assessed preoperatively and postoperatively at 3, 6, 12, and 24 months using the International Index of Erectile Function (IIEF)-5, a percent erection fullness compared to preoperative status, and two Expanded Prostate Cancer Index (EPIC) questions: (1) are erections firm enough for penetration and (2) are they satisfactory?ResultsTwo hundred thirty-one (33.1%) men had APAs transected. There were no significant differences in baseline demographics or clinical characteristics in men with or without APAs transected. Multivariate analyses demonstrated that age (confidence interval [95% CI]: 0.94, 0.99) and baseline IIEF-5 (95% CI: 1.15, 1.26) strongly correlated with recovery of erections and potency. Transection of APAs was not a significant predictor of erectile dysfunction (ED).ConclusionGood surgical technique dictates the preservation of APAs. However, when preservation is questioned, we found that APA transection had no measurable effect on recovery of erections or potency regardless of age, preoperative ED, or number of APAs transected.

Pseudoaneurysms are rare complications in urological surgery. Typically, they would present with pain, haematuria or anaemia. We report a 60-year-old patient who was found to have a chronic pseudoaneurysm via a corona mortis vascular variant, 3 months after a robotic-assisted prostatectomy. Unlike other rare reports of delayed vascular complications after minimally invasive urological surgery, the patient was entirely asymptomatic.Apart from careful intraoperative dissection, a high index of suspicion and low threshold for imaging are also required in the follow up period. Percutaneous trans-arterial embolization is safe and effective in dealing with post-surgical pseudoaneurysms.

This study intended to assess the safety and feasibility of performing concurrent robotic-assisted laparoscopic prostatectomy (RALP) and robotic inguinal hernia repair (RIHR). We systematically searched the PubMed, Embase and Cochrane Library database up to the year 2020 to identify studies that assessed patients who underwent RALP and RIHR in the same settings. Thirteen studies were considered suitable for a systematic review and seven for Meta-analysis. RALP and RIHR were associated with significantly longer operative time. RIHR added on average 26 min to the operation time (8, 45 95% CI, p = 0.005, I2 97%). Concurrent RALP and RIHR was not associated with a higher incidence of blood loss (−13, 6 95% CI, p = 0.43, I2 18%), length of stay (−0.08, 0.06 95% CI, p = 0.73, I2 0%) or early postoperative complications. Concurrent robotic repair of an inguinal hernia during RALP appears feasible and safe. Urologists should be encouraged to repair hernias encountered during RALP keeping in mind possible complications including wound infection, mesh infection, chronic inguinal pain and recurrence of hernia.

The purpose of the study is to evaluate the impact of a multimodal Enhanced Recovery After Surgery (ERAS) protocol on perioperative opioid consumption and hospital length of stay (LOS) after robotic-assisted radical prostatectomy (RARP). We compared the first 176 patients enrolled in the protocol (ERAS group) with the previous 176 patients (non-ERAS group) at a single quaternary institution from December 2017 to June 2019. The ERAS protocol included a multimodal opioid-sparing regimen utilizing acetaminophen, gabapentin, celecoxib, and liposomal bupivacaine. Demographic data, co-morbidities, post-operative pain scores, post-operative opiate consumption measured by morphine milligram equivalents (MME), operating time, and LOS were collected. The two groups were compared using chi-squared, Fisher exact, or Student t tests as appropriate. Multivariable logistic regression analysis was performed to identify predictors of prolonged LOS (> 1 day). The ERAS and non-ERAS groups were equivalent in terms of baseline characteristics and pathological data. The ERAS group had lower post-operative pain scores, post-operative opiate consumption (MME 15 vs. 46, p < 0.01), and LOS (1.2 vs. 1.7 days, p < 0.01) compared to the non-ERAS group. Only 22% in the ERAS cohort had a prolonged LOS compared to 39% of the non-ERAS group (p < 0.01). The ERAS protocol was a negative predictor of prolonged LOS on multivariable logistic regression analysis (odds ratio 0.39, 95% confidence interval 0.22–0.70, p < 0.01). A limitation of this study is its single-center retrospective design. The implementation of a multimodal opioid-sparing ERAS protocol was associated with improved pain control, reduced perioperative opioid usage, and shorter LOS after RARP. [ABSTRACT FROM AUTHOR]

Background: To determine safety and feasibility of single-port Retzius-sparing robot-assisted radical prostatectomy (SP-rsRARP) using the da Vinci® SP (Intuitive Surgical, Sunnyvale, CA) robotic platform in men with adenocarcinoma of the prostate. Patients and Methods: Twenty-eight consecutive men with prostate cancer underwent SP-rsRARP by one of two surgeons (J.B., S.C.). Data for perioperative, pathologic, and functional outcomes were collected prospectively and retrospectively analyzed. Results: Mean (standard deviation) follow-up was 6 (3) months. Mean age was 65.3 years old with an average body mass index of 25.2 kg/m2. Mean preoperative prostate-specific antigen (PSA) was 10.2 ng/mL. Average prostate weight was 42 g. Three patients (11%) had prior radiation to the prostate. There were no intraoperative complications or conversions of technique. Lymphadenectomy was performed in 24 (86%) patients and nerve sparing in 14 (46%) patients. Mean operative time (skin to skin) was 234 minutes with an average estimated blood loss of 148 mL. Length of hospital stay averaged 23 hours. Seventeen (61%) of the patients did not require opioids for postoperative pain. Two Clavien Grade IIIa complications occurred (lymphocele aspiration and dilation of bladder neck contracture). Pathologic grade group was group 1 (0%), group 2 (57%), group 3 (29%), and group 4–5 (14%). Pathologic stage was T2 (15/28, 54%) and T3a,b (13/28, 46%). Five patients (18%) had a positive surgical margin, four (80%) of whom had T3 disease. One patient (4%) had a detectable PSA during follow-up and opted for adjuvant radiation. Twenty-three patients (82%) were continent at foley removal. Postoperative mean sexual health inventory for men score in those who underwent nerve sparing was 18 at 3 months follow-up. Conclusions: SP-rsRARP appears safe and feasible. Early continence rates are promising. Full characterization of outcomes requires longer follow-up and larger cohort validation.

Several benefits have been reported after applying the principles of enhanced recovery after surgery (ERAS) into the perioperative care of patients undergoing robot-assisted radical prostatectomy (RARP). Nevertheless, there are still barriers. We aimed to identify the key areas by systematically surveying urology departments in Germany and Austria. A 27-question survey on the adoption of ERAS principles for the perioperative care of RARP patients was designed, in compliance with the guidelines on good practice in conducting and reporting of survey research. After positive testing for face and content validity, the survey was distributed via postal mail to 82 departments performing RARP. In total, 39 departments responded to our survey (response rate 48%). The ERAS adoption rates ranged from 21 to 97%, with nine ERAS principles being widely adopted (72–92% of the departments). The lowest adoption rates and, subsequently, the largest potential for optimization were detected for the preoperative nutrition counselling (21%), preoperative pelvic floor physiotherapy (54%), postoperative early initiation of nutrition (44%) and postoperative patient audit for further quality improvement (36%). High-volume centers performed more frequently a perioperative nutrition counselling (8/27; 30%) than low-volume centers (0/12; 0%; p = 0.036). The implementation of the ERAS principles into the perioperative care algorithm were medium-to-high, yet not optimal. Our real-world data assessment revealed four key areas showing low adoption rates (nutrition counselling, preoperative pelvic floor physiotherapy, early initiation of nutrition and patient audit), implying a great potential for further optimization.

INTRODUCTION: The aim of this study was to compare the results of patients who underwent robot-assisted radical prostatectomy (RARP) over 70 years old and those who underwent RARP under 70 years old. METHODS: A total of 1019 cases performed by 4 surgeons between February 2009 and December 2018 were reviewed retrospectively. First 50 cases of each surgeon were not included to exclude the learning curve effect. All patients (n = 819) were divided into two groups according patient age, Group 1 = ≥70 years old (n = 151), Group 2 =

Introduction: Robotic prostatectomy requires pneumoperitoneum and a steep Trendelenburg position; however, this condition may compromise cerebral blood flow. Here, we evaluated the effect of pneumoperitoneum and the steep Trendelenburg position on internal carotid artery (ICA) blood flow measured by Doppler ultrasound during robotic prostatectomy. Methods: Patients who underwent robotic prostatectomy were prospectively recruited. The ICA blood flow was measured at the following five time‐points: with the patient awake and in the supine position (Ta), 10 min after anaesthetic induction in the supine position (T1), 10 (T2) and 30 (T3) min after pneumoperitoneum in the steep Trendelenburg position, and at the end of surgery in the supine position after desufflation of the pneumoperitoneum (T4). Hemodynamic and cerebrovascular variables were measured at each time‐point. Results: A total of 28 patients were evaluated. The ICA blood flows were significantly lower at T2 and T3 than at T1 (162.3 ± 44.7 [T2] vs. 188.0 ± 49.6 ml/min [T1]; p =.002, 163.1 ± 39.9 [T3] vs. 188.0 ± 49.6 ml/min [T1]; p =.009). The ICA blood flow also differed significantly between Ta and T1 (236.8 ± 58.3 vs. 188.0 ± 49.6 ml/min; p <.001). Heart rates, cardiac indexes, peak systolic velocity, and end‐diastolic velocity were significantly lower at T2 and T3 than at T1. However, ICA diameter, mean blood pressure, and end‐tidal carbon dioxide partial pressure did not differ significantly at all time‐points. Conclusion: Pneumoperitoneum and the steep Trendelenburg position caused decreased ICA blood flow, suggesting that they should be carefully performed during robotic prostatectomy, especially in patients at risk of postoperative cerebrovascular accident.

Purpose: This study aims to compare perioperative and oncologic outcomes between matched cohorts of localized prostate cancer (PCa) operated on by the same surgeon using the da Vinci Si robot and the Revo-i robot. Materials and Methods: Nonmetastatic PCa patients undergoing Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RS-RARP) from January 2016 to December 2020 were matched one-to-one (33:33) to da Vinci Si controls using propensity score matching according to the following covariates: age, American Society of Anesthesiology (ASA) score, body mass index, previous abdominal and endoscopic surgery, preoperative prostate specific antigen, prostate volume, Gleason grade group, tumor stage, and need for pelvic lymphadenectomy. Outcomes of interest were estimated blood loss, length of stay, complication rate, operative times, positive surgical margins, and biochemical recurrence at 6 months. Results: Both cohorts were similar in estimated blood loss, rate of margin positivity, and rate of complications. Length of stay was significantly shorter with the Revo-i cohort. The da Vinci robot showed faster console, suture, and total operation times. Positive margin rate and biochemical recurrence at 6 months were similar in both groups. Conclusion: Despite the longer suture, console, and operative time those in the da Vinci robot in the authors' institution, the Revo-i robot-assisted radical prostatectomy had equivalent short-term oncologic outcomes with the da Vinci standard.

During robotic-assisted radical prostatectomy (RARP), the use of electrocautery near the neurovascular bundles (NVBs) frequently results in thermal injury to the cavernous nerves. The cut and "touch" monopolar cautery technique has been suggested to reduce desiccating thermal injury caused by bipolar energy when vessels are sealed. To compare potency outcomes between an athermal technique (AT) and touch cautery (TC) to transect the prostatic vascular pedicles (PVPs) and dissect the NVBs. A retrospective concomitant nonrandomized study of AT versus TC was performed in 733 men. A total of 323 undergoing AT had "thin" pedicles, easily suitable for suture ligation. TC was based on "thick" pedicles (n = 230) difficult to suture ligate. Men were excluded for an International Index of Erectile Function (IIEF-5) score of <15 or adjuvant therapies (n = 180). Single-surgeon RARP. Patient-reported outcomes with erectile function (EF) recovery defined as two affirmative answers to erections sufficient for intercourse (ESI; "are erections firm enough for penetration?" and "are the erections satisfactory?"), IIEF-5 scores 15–25, and a novel percent fullness score comparing pre- versus postoperative erection fullness. Logistic regression models assessed the correlation between cautery technique, covariates, and EF recovery. In an unadjusted analysis, preoperative IIEF-5, age, body mass index (BMI), and prostate weight were significant predictors of potency recovery. Follow-up was similar (AT 52.7 mo vs TC 54.6 mo, p = 0.534). In logistic regression, preoperative IIEF-5, age, and BMI were significant predictors of EF recovery, defined as IIEF-5 scores 15–25, ESI, and percent fullness >75%. Results were similar when IIEF-5 and percent fullness were assessed continuously. During transection of the PVPs and dissection of the NVBs, TC did not impact EF recovery significantly, compared with an AT. Electrocautery can be applied safely, with similar outcomes to those of an athermal technique. During transection of the prostatic vascular pedicle and dissection of the neurovascular bundle, "touch" cautery did not significantly impact erectile function recovery compared with an athermal technique. The thermodynamic laws of "heat sinking" and avoiding desiccation via touch cautery lend evidence of a method for safe use of cautery. [ABSTRACT FROM AUTHOR]
