Robot-Assisted Radical Prostatectomy Performed with the Novel Hugo™ RAS System: A Systematic Review and Pooled Analysis of Surgical, Oncological, and Functional Outcomes.

Background/Objectives: to assess surgical, oncological, and functional outcomes of robot-assisted radical prostatectomy (RARP) performed using the novel Hugo™ RAS system. Methods: A systematic review was conducted following the PRISMA guidelines, using PubMed, Web of Science, Scopus, and Embase databases. Eligible papers included studies involving adult males undergoing RARP with the Hugo™ RAS platform, with at least ten patients analyzed. The pooled analysis was performed using a random-effect model. Results: Quantitative analysis was conducted on 12 studies including 579 patients. The pooled median docking time, console time, and operative time were 11 min (95% CI 7.95-14.50; I2 = 98.4%, ten studies), 142 min (95% CI 119.74-164.68; I2 = 96.5%, seven studies), and 176 min (95% CI 148.33-203.76; I2 = 96.3%, seven studies), respectively. The pooled median estimated blood loss was 223 mL (95% CI 166.75-280.17; I2 = 96.5%, eleven studies). The pooled median length of hospital stay and time to catheter removal were 2.8 days (95% CI 1.67-3.89; I2 = 100%, ten studies) and 8.3 days (95% CI 5.53-11.09; I2 = 100%, eight studies), respectively. The pooled rate of postoperative CD ≥ 2 complications was 4.1% (95% CI 1-8.5; I2 = 63.6%, eleven studies). The pooled rate of positive surgical margins and undetectable postoperative PSA were 20% (95% CI 12.6-28.5; I2 = 71.5%, nine studies) and 94.2% (95% CI 87.7-98.6; I2 = 48.9%, three studies), respectively. At three months, a pooled rate of social continence of 81.9% (95% CI 73.8-88.9; I2 = 66.7%, seven studies) was found. Erectile function at six months was 31% in one study. Conclusions: despite the preliminary nature of the evidence, this systematic review and pooled analysis underscores the feasibility, safety, and reproducibility of the Hugo™ RAS system in the context of RARP.

Assessing Trifecta and Pentafecta Success Rates between Robot-Assisted vs. Open Radical Cystectomy: A Propensity Score-Matched Analysis.

BACKGROUND: This study aimed to evaluate the surgical and oncological outcomes of robot-assisted radical cystectomy (RARC) versus open radical cystectomy (ORC) using trifecta and pentafecta parameters. METHODS: The clinical data of 41 patients who underwent RARC between 2018 and 2022 were prospectively collected and retrospectively compared to those of 330 patients undergoing ORC using 1:1 propensity score matching. Trifecta was defined as simultaneous negative surgical margins (SMs), a lymph node (LN) yield ≥ 16, and the absence of major complications (Clavien-Dindo grade III-V) within 90 days postoperatively. Pentafecta additionally included a 12-month recurrence-free rate and a time between the transurethral resection of a bladder tumor (TURBT) and radical cystectomy (RC) ≤ 3 months. The continuous variables were compared using the Mann-Whitney U test, and the categorical variables were analyzed using the chi-squared test. RESULTS: No statistically significant differences in trifecta and pentafecta success rates were observed between the RARC and ORC cohorts after propensity score matching. However, the RARC group exhibited significantly reduced blood loss (RARC: 317 mL vs. ORC: 525 mL, p = 0.01). CONCLUSIONS: RARC offers distinct advantages over ORC in terms of reduced blood loss, while trifecta and pentafecta success rates do not differ significantly between the two surgical approaches.

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.

Elderly and bladder cancer: The role of radical cystectomy and orthotopic urinary diversion.

The incidence of bladder cancer (BC) depends on advancing age and other risk factors, significantly impacting on surgical, functional and oncological outcomes. Radical cystectomy (RC) with urinary diversion is the gold standard therapy for muscle invasive bladder cancer; however, it remains a complex surgery and requires careful analysis of risk factors in order to potentially decrease post-surgical complication rates. Age in surgery is a limiting factor that can modify surgical and oncological outcomes, and is correlated with a high rate of post-dimssion hospital readmissions. The reconstruction of the bladder with the intestine represents a crucial point of radical cystectomy and the urinary derivation (UD) is at the center of many debates. A non-continent UD seems to be the best choice in elderly patients (>75 years old), while orthotopic neobladder (ON) is poorly practiced. We reviewed the literature to identify studies reporting outcomes, complications, patient- selection criteria, and quality-of-life data on elderly patients, who underwent ON following radical cystectomy. Reviewing the literature there is no clear evidence on the use of age as an exclusion criterion. Certainly, the elderly patient with multiple comorbidities is not eligible for ON, preferring other UD or rescue therapies. A careful preoperative selection of elderly patients could greatly improve clinical, surgical and oncological outcomes, giving the chance to selected patients to receive an ON.

Efficacy of transurethral botulinum toxin A injections for bladder outlet obstruction: A systematic review and meta-analysis.

INTRODUCTION: Botulinum toxin A (BoNT-A) injections in the prostate gland have been used as a minimally invasive option for treating bladder outlet obstruction (BOO). However, the efficacy of transurethral BoNT-A injections for BOO is not well established in the literature. The aim of this study is to collect evidence on the efficacy of transurethral BoNT-A injections for the treatment of BOO. MATERIALS AND METHODS: This systematic review and meta-analyses was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. A systematic literature search was performed till December 2022. The study population consisted of adult patients diagnosed with BOO, who underwent transurethral injections of BoNT-A for the treatment of BOO. EVIDENCE SYNTHESIS: Out of 883 records, we identified seven studies enrolling 232 participants, of which only one nonrandomized controlled trial was found. Four prospective studies and two retrospective studies. Three studies included patients with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) and were included in the meta-analysis. Three studies included patients with urethral sphincter hyperactivity. One study included patients with primary bladder neck disease (PBND). All studies showed significant improvements from baseline in maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and postvoid residual (PVR) at 3 and 6 months. The adverse events were mild in all studies. Hematuria, UTI, and urinary retention were reported across all studies. CONCLUSION: In conclusion, transurethral BoNT-A injections have been shown to improve LUTS, QoL, and urodynamic parameters of individuals with BOO at 3 and 6 months after injections, and no serious adverse effects have been reported. However, data on the long-term benefits of this treatment are scarce, and more prospective, randomized studies with larger samples examining various injection techniques, dosages, and extended follow-up of recurrent injections are needed.

Risk factors for hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation in a letermovir-exposed CMV-free population receiving PTCy.

Hemorrhagic cystitis (HC) is a highly impacting complication in allogeneic hematopoietic stem cell transplantation (HSCT), occurring in 12%-37% of patients. The impact of transplant- and patient-specific variables has been described, with a possible role for JCV and BKV, which may be cooperating with cytomegalovirus (CMV). Here, we analyze 134 letermovir-exposed, CMV-free patients, treated with the same cyclophosphamide-based graft-versus-host disease (GVHD) prophylaxis, describing risk factors for HC. The overall incidence of HC was 23%. Patients with HLA mismatched transplant, higher comorbidity score, and receiving three alkylating agents with TBF (thiotepa, busulfan, and fludarabine) conditioning regimen had a higher risk of HC in multivariate analysis (OR: 4.48, 6.32, and 1.32, respectively). A HC-score including male gender, TBF conditioning, and HLA-mismatch stratifies the risk of HC in the first 100 days after HSCT. The role of BKV and JCV was not highly impacting in those patients, suggesting a possible synergistic effect between CMV and JCV in causing HC. HC can be interpreted as the combination of patient-related factors, chemotherapy-related toxicities-especially due to alkylating agents-and immunological elements.

Prevalence and Antimicrobial Resistance Patterns of Hospital Acquired Infections through the COVID-19 Pandemic: Real-Word Data from a Tertiary Urological Centre.

BACKGROUND: Antimicrobial resistance (AMR) remains a significant public health concern, closely linked to antibiotic overuse. During the COVID-19 pandemic, broad-spectrum antibiotics were frequently administered, potentially exacerbating AMR. This study aimed to assess AMR patterns in our urology department before and after the pandemic. METHODS: The study encompassed patients admitted to our urology department from January 2016 to December 2022, with confirmed urinary tract infection, bloodstream infection, or wound infection based on positive culture results. Descriptive statistics, including mean, frequency, and percentage, summarized the data. Trends were analyzed using the Joinpoint Regression program. RESULTS: A total of 506 patients were included. Escherichia coli and Klebsiella pneumoniae displayed resistance rates of 65% and 62% to ciprofloxacin, respectively. K. pneumoniae showed resistance rates of 41% to piperacillin tazobactam and 3rd generation cephalosporins (3GC). Carbapenem resistance was observed in 38% of K. pneumoniae isolates. Additionally, 26% of E. coli, 26% of K. pneumoniae, and 59% of Proteus mirabilis isolates were ESBL-positive. Among gram+, 72% of Staphylococcus aureus isolates were MRSA, and 23% of Enterococcus faecium isolates were VRE. Trends in antimicrobial susceptibility patterns over the 7-year study period revealed a statistically significant decrease in E. coli resistance to amoxicillin-clavulanic acid (APC: -5.85; C.I. 95% p < 0.05) and a statistically significant increase in K. pneumoniae resistance to 3GC (APC: 9.93; CI (-19.9-14.4 95% p < 0.05). There were no statistically significant differences in AMR incidence pre- and post-COVID-19. CONCLUSION: The COVID-19 pandemic did not appear to influence the AMR incidence in our urology department. However, the overall prevalence of AMR and MDROs in our department remains high compared to European AMR.

What can the metaverse do for urology?

Everyone talks about the metaverse but few know what it really is. Augmented reality, virtual reality, internet of things (IoT), 5G, blockchain: these are just some of the technologies underlying the structure of the metaverse, a sort of parallel dimension in which the physical and virtual worlds merge together enabling users to interact by emerging technologies in order to enhance their actions and decisions. The healthcare scientific community is already looking at the metaverse as a new research frontier, a tool to improve medical knowledge and patient care. We reviewed the metaverse applications and services, looking for those that could best be developed in the urological field. Urology, due to its technological nature, is a privileged laboratory for experimenting and exploiting the applications of the metaverse both inside and outside the operating room. The revolution of the metaverse is already happening, which is why it is necessary that urologists face it as protagonists in order to lead it in the right direction.

Classification and management of sexual dysfunctions in multiple sclerosis patients: A review of current literature.

Multiple sclerosis (MS) is the most frequent neurological disease in young adults, with the greatest incidence between age of 30 and 35 years. Sexual dysfunctions (SDs) are frequent, but are often underestimated in patients with MS, and can have a significantly high impact on patient's quality of life. Aim of this review is to summarize sexual dysfunctions in male and female MS patients and to illustrate current and emerging therapeutic options for treatment.

Robotic versus Open Pyeloplasty: Perioperative and Functional Outcomes.

We designed a retrospective study to assess the surgical and economic outcomes of robot-assisted laparoscopic pyeloplasty (RALP) compared with open pyeloplasty (OP), including consecutive patients suffering from ureteropelvic junction obstruction and operated on from January 2012 to January 2022 at a single center. Preoperative, intraoperative, and postoperative outcomes, including costs, were comparatively analyzed. The primary outcome was 3-month success, defined as symptom resolution and no obstruction upon diuretic renal scintigraphy. Overall, 91 patients were included (48 OP and 43 RALP). The success rate at 3 months was 93.0% and 83.3% in the RALP and OP group, respectively (p = 0.178), and the results remained stable at the last follow-up (35.4 ± 22.8 months and 56.0 ± 28.1 months, respectively). Intraoperative blood loss (p < 0.001), need for postoperative analgesics (p = 0.019) and antibiotics (p = 0.004), and early postoperative complication rate (p = 0.009) were significantly lower in the RALP group. None of the assessed variables were a predictor for failure. The mean total direct cost per surgical procedure and related hospital stay was 2373 € higher in the RALP group. RALP is an effective and safe treatment for ureteropelvic junction obstruction; however, further studies are needed to evaluate the cost-effectiveness of RALP, accounting for indirect costs and cost-saving with new surgical platforms.

Transalbugineal Artificial Urinary Sphincter: A Refined Implantation Technique to Improve Surgical Outcomes.

The artificial urinary sphincter (AUS) implantation is an effective treatment of post-prostatectomy urinary incontinence (PPI). Still, it may result in troublesome complications such as intraoperative urethral lesion and postoperative erosion. Based on the multilayered structure of the tunica albuginea of the corpora cavernosa, we evaluated an alternative transalbugineal surgical technique of AUS cuff placement with the aim to decrease perioperative morbidity while preserving the integrity of the corpora cavernosa. A retrospective study was conducted in a tertiary referral center from September 2012 to October 2021, including 47 consecutive patients undergoing AUS (AMS800®) transalbugineal implantation. At a median (IQR) follow-up of 60 (24-84) months, no intraoperative urethral injury and only one noniatrogenic erosion occurred. The actuarial 12 mo and 5 yr overall erosion-free rates were 95.74% (95% CI: 84.04-98.92) and 91.76% (95% CI: 75.23-97.43), respectively. In preoperatively potent patients, the IIEF-5 score remained unchanged. The social continence (0-1 pads per day) rate was 82.98% (CI 95%: 68.83-91.10) at 12 mos and 76.81% (CI 95%: 60.56-87.04) at 5 yrs follow-up. Our technically refined approach to AUS implantation may help to avoid intraoperative urethral lesions and lower the risk of subsequent erosion without compromising sexual function in potent patients. Prospective and adequately powered studies are necessary to achieve more compelling evidence.

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.

Germline mutations in prostate cancer: a systematic review of the evidence for personalized medicine.

BACKGROUND: The goal of precision medicine in prostate cancer (PCa) is to individualize the treatment according to the patient's germline mutation status. PCa has a very high rate of genetic predisposition compared with other cancers in men, with an estimated rate of cancers ascribable to hereditary factors of 5-15%. METHODS: A systematic search (PubMed, Web of Science, and ClinicalTrials.gov) of English literature from 2000 to 2022, using the keywords "prostate cancer", "germline mutations", "family history", and "inheritance" was conducted, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. RESULTS: The search identified 980 publications. Of these, 200 papers were removed before screening (duplicates, non-English literature, and publication year before 2000) and 245 records were excluded after title/abstract screening. Finally, 50 articles were included in the final analysis. We analyze the latest evidence on the genetic basis of PCa predisposition and clinical implications for more personalized screening protocols and therapeutic management of this high-prevalent cancer. DISCUSSION: Emerging data show that germline mutations in homologous recombination genes (BRCA1/2, ATM, CHECK2), in mismatch repair genes (MLH1, MLH2, MSH6), and other additional genes are associated with the development and aggressiveness of PCa. Germline testing and genetic counseling have increasingly important implications in cancer screening and therapeutic decisions making for patients affected by PCa. Patients with localized PCa and some gene mutations are more likely to develop aggressive cancer, so active treatment may be preferable to active surveillance for these patients. Moreover, in patients with metastatic PCa, these gene alterations may be useful biomarkers for predicting response to specific therapy such as PARP inhibitors, recently approved for the treatment of metastatic castration-resistant PCa. The evidence supports recent guidelines and recommendations considering germline genetic testing for patients with a positive family history of PCa or men with high risk or metastatic disease.

Purely Off-Clamp Partial Nephrectomy: Robotic Approach Better than Open Using a Pentafecta Outcome with Propensity Score Matching.

Partial nephrectomy (PN) is the gold standard treatment for localized renal masses. Robot-assisted PN (RAPN) has overcome laparoscopy's technical limitations, greatly expanding the indications of minimally invasive PN, which is dominated by renal artery clamping in almost all published series. We compared off-clamp RAPN (OFFC-RAPN) with the open approach (OFFC-OPN) using propensity score (PS) matching. A favourable pentafecta outcome was defined as a combination of no positive surgical margins (PSM), no complications of Clavien−Dindo (CD) grade ≥ 3, post-operative eGFR loss <10%, length of hospital stay (LOS) ≤ 5 days and estimated blood loss (EBL) < 200 mL. A total of 340 consecutive patients were included. The PS-matched cohort included 142 patients: 71 matched pairs well-balanced for all covariates. The OFFC-RAPN group showed significantly shorter operative time (149.8 vs. 173.9 min, p = 0.003), lower EBL (182.1 vs. 329.3 mL, p = 0.001), and shorter LOS (5.8 vs. 6.9 days, p = 0.02), with a higher proportion of patients with LOS ≤ 5 days (57.7% vs. 23.9%, p < 0.001). No significant differences were found for PSM rate (2.8% vs. 8.4%, p = 0.27), CD > 2 complication rate (4.2% vs. 2.8%, p = 1.00) and mean ± SD eGFR change (−0.06 ± 0.3 vs. −0.8 ± 0.3, p = 0.5). Pentafecta was achieved in 56.3% and 21.1% in the OFFC-RAPN and OFFC-OPN series, respectively (p < 0.0001). On multivariable analysis, surgical approach and BMI proved to be independent predictors of achieving pentafecta. After adjusting for potential treatment selection bias, OFFC-RAPN outperformed OFFC-OPN for important peri-operative outcomes, without compromising oncological and functional safety.

The Impact of Neurogenic Lower Urinary Tract Symptoms and Erectile Dysfunctions on Marital Relationship in Men with Multiple Sclerosis: A Single Cohort Study.

Aims: Multiple sclerosis (MS) is an autoimmune and neurodegenerative disease that is characterized by a great variety symptoms. Most MS patients suffer from neurogenic lower urinary tract symptoms (nLUTS) and erectile dysfunctions (ED). The aim this study is to assess the impact of nLUTS and ED on marital relationships in MS patients. Materials and Methods: MS male patients that arrived for our attention were prospectively enrolled in the study. All of the patients were evaluated on an Expanded Disability Status Scale (EDSS), an IIEF-5 for sexual function, an ICIQ-MLUTS for urinary function, and a Dyadic Adjustment Scale (DAS) for marital relationships. The data were analyzed using descriptive and inferential statistical tests in STATA/MP14. Results: The data of 57 male MS patients were eligible. The mean age was 45 (13.7) years, the mean disease duration was 15.49 (7.86) years, and the mean EDSS score was 3.5 (1.89). In total, 33 (57.89%) MS patients reported urine incontinence, of those, 24 (42.11%) reported UUI. The mean DAS score was 74.40 (34.58). The mean IIEF-5 score was 12.40 (8.05). The mean ICIQ-MLUTS score was 71.94 (41.06). The DAS and ICIQ-MLUTS scores were negatively correlated (r = −0.30, p < 0.001). The DAS and IIEF-5 were moderately correlated (r = 0.47, p < 0.001). The DAS and EDSS were strongly correlated (r = −0.72, p < 0.001). A univariate analysis showed that increasing age (p < 0.001), a longer disease duration (p = 0.029), a higher EDSS score (p < 0.001), and a higher ICIQ-MLUTS score (p < 0.001) were all significantly associated with lower DAS scores. Conclusions: This study demonstrated the large negative impact that nLUTS and ED due to MS have on patients' marital relationships, highlighting the importance of a multidisciplinary approach in MS patients.

The new surgical robotic platform HUGOTM RAS: System description and docking settings for robot-assisted radical prostatectomy.

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.

InTrathecal mORphine, traNsversus Abdominis Plane Block, and tramaDOl Infusion for Catheter-Related Bladder Discomfort in Patients Undergoing Robot-Assisted Laparoscopic Prostatectomy (TORNADO): A Pilot Prospective Controlled Study.

Catheter-related bladder discomfort (CRBD), affecting surgical patients requiring large catheters, is often intolerable. In this prospective controlled study, we compared the efficacy of three analgesic approaches in the management of CRBD. Here, 33 patients undergoing robot-assisted laparoscopic prostatectomy (RALP) were allocated to the following three groups: intrathecal morphine (IM), transversus abdominis plane block (TAP), and tramadol intravenous infusion (TI). The primary outcome was CRBD assessed at admission in the recovery room (RR) (T0), and 1 h (T1), 12 h (T2), and 24 h (T3) after surgery. The secondary outcomes included the following: Aldrete score; postoperative pain, measured with a numerical rate scale (NRS) at T0, T1, T2, and T3; postoperative opioid consumption; and flatus. The patients of the IM group showed significantly lower CRBD values over time compared to the patients of the TI group (p = 0.006). Similarly, NRS values decreased significantly over time in patients receiving IM compared to patients treated with TI (p < 0.0001). Postoperative nausea and vomiting did not differ among the three groups. Postoperative opioid consumption was significantly lower in the IM group compared to the other two groups. Most patients of the IM group (9 of 11) had flatus on the first postoperative day. In conclusion, IM may prevent CRBD and reduce pain perception and postoperative opioid consumption and expedite bowel function recovery.

A multi-surgeon learning curve analysis of overall and site-specific positive surgical margins after RARP and implications for training.

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.

Male sling placement for post-prostatectomy incontinence can involve a lengthy learning curve: A multi-outcome assessment via cumulative sum failure analysis.

PURPOSES: Little research exists on potential learning curve for male sling procedures. We aimed to perform a learning curve analysis of a single surgeon's experience of sling placement evaluating multiple outcomes and using the cumulative sum failure methodology. METHODS: The study included 65 consecutive patients that underwent implantation of a fixed transobturator sling (TiLOOP Male) for post-radical prostatectomy stress incontinence at our institution from January 2013 to December 2018. Dichotomous outcomes evaluated with cumulative sum failure analysis included 12-months continence defined based on Patient Global Impression of Improvement (PGI-I) questionnaire (primary outcome), 24 h pad test and, 24 h pad use, operative time (⩽/>60 min), and complications (yes/no). Univariate and multivariate logistic regression analyses were performed to evaluate the association of the procedures' chronological sequence number with the outcomes. RESULTS: Cumulative sum failure curves revealed a clear and lengthy learning curve effect for most of subjective and quantitative continence outcomes and for operative time. For the primary outcome (at least much improved at PGI-I), 62 procedures were required to overcome the learning curve. Accordingly, multivariate analyses showed that the sequence number was statistically significant for predicting failures based on PGI-I (adjusted OR 0.95; 95% CI: 0.91-0.99; p = 0.02), objective outcomes, and operative time. CONCLUSIONS: An evident and lengthy learning curve was observed in our series of male sling placement to achieve the end level of proficiency, independently from case-mix. Individualized structured training on male sling surgery will benefit patients treated in the initial surgeon's experience. Surgical experience should be considered when reporting studies on male slings.

Pharmacological Management of Urinary Incontinence: Current and Emerging Treatment.

Pharmacological management of urinary incontinence (UI) is currently based on antimuscarinic and beta-3-agonist drugs. Botulinum toxin A detrusor injections represent an effective but more invasive alternative. This review covers the latest developments of the currently available drugs and the emerging compounds for the treatment of UI. Evidence shows that new antimuscarinics and beta-3-agonists with improved safety profiles may offer unique options to patients intolerant to currently available drugs. Combination therapy proved to be a non-invasive alternative for patients refractory to first-line monotherapy. Exciting advances are ongoing in the research to improve the efficacy/tolerability profile of botulinum toxin, through innovative routes of administration. Several new agents emerged from preclinical studies, some of which have now entered the clinical phase of development and could represent, in the coming years, a new way for the treatment of UI. Recent evidence on the existence of different overactive bladder phenotypes could be the key to tailored treatment. Rather than discovering new molecules, reaching the ability to identify the right drug for the right patient could be the real gamechanger of the future.
