The use of Versius CMR for pelvic surgery: a multicentric analysis of surgical setup and early outcomes.

INTRODUCTION: Versius CMR is a novel robotic system characterized by an open surgical console and independent bedside units. The system has potentials of flexibility and versatility, and has been used in urological, gynecological, and general surgical procedure. The aim is to depict a comprehensive analysis of the Versius system for pelvic surgery. METHODS: This is a study involving two Institutions, ASST Santi Paolo and Carlo, Milan, and Apuane Hospital, Massa, Italy. All interventions performed in the pelvic area with the Versius were included. Data about indications, intra-, and post-operative course were prospectively collected and analyzed. RESULTS: A total of 171 interventions were performed with the Versius. Forty-two of them involved pelvic procedures. Twenty-two had an oncological indication (localized prostate cancer), the remaining had a non-oncological or functional purpose. The mostly performed pelvic procedure was radical prostatectomy (22) followed by annexectomy (9). No intra-operative complication nor conversion to other approaches occurred. A Clavien II complication and one Clavien IIIb were reported. Malfunctioning/alarms requiring a power cycle of the system occurred in 2 different cases. An adjustment in trocar placement according to patients' height was required in 2 patients undergoing prostatectomy, in which the trocar was moved caudally. In two cases, a pelvic prolapse was repaired concomitant with other gynecological procedures. CONCLUSIONS: Pelvic surgery with the Versius is feasible without major complications; either dissection and reconstructive steps could be accomplished, provided a proper OR setup and trocar placement are pursued. Versius can be easily adopted by surgeons of different disciplines and backgrounds; a further multi-specialty implementation is presumed and long-term oncological and functional outcomes are awaited.

Reproducibility of a modified posterior reconstruction during robotic intracorporeal neobladder reconfiguration.

OBJECTIVE: Robotic intracorporeal neobladder reconstruction is a complex procedure in which the approximation of the reservoir to the urethral stump can be a demanding step. The aim of the study is to evaluate the reproducibility of a modified posterior reconstruction (PR) during the reconfiguration of intracorporeal neobladder after robot assisted radical cystectomy (RARC). MATERIALS AND METHODS: From July 2021 to July 2022, 35 RARC were performed, and 17 patients underwent intracorporeal neobladder reconstruction. A PR was planned in males (14). Intra- and peri-operative data were collected. SURGICAL TECHNIQUE: RARC and node dissection are performed. Afterwards, 40-cm ileal segment is isolated; the portion with the more adequate mesenteric length is brought down to the pelvis. A modified PR is performed with a double-armed barbed suture: a first layer connects the Denonvillier's fascia to the rhabdosphincter in a running fashion; the second layer is created with the other arm and approximates the posterior side of the ileal segment towards the urethral stump. In the anterior caudal part of the ileum, a 1.5-cm incision is made to realize the neobladder neck; the neovesical-urethral anastomosis is performed with a second bidirectional suture. RESULTS: Anastomotic and PR time were 14 (range 7-20) and 5 minutes (4-8), respectively. A single Clavien IIIa complication was recorded in a patient who underwent NAC and had a C. albicans superinfection in the post-operative course. All patients were discharged with complete or acceptable bladder voiding. Twelve patients with follow-up >90-days reported a satisfying daytime continence. CONCLUSIONS: PR represents a simple technical refinement that improves neobladder-urethral anastomosis by favoring ileal approximation to the urethral stump and decreasing anastomotic tension.

Cost analysis of new robotic competitors: a comparison of direct costs for initial hospital stay between Da Vinci and Hugo RAS for radical prostatectomy.

Robotic surgery with Da Vinci has revolutionized the treatment of several diseases, including prostate cancer; nevertheless, costs remain the major drawback. Recently, new robotic platforms entered the market aiming to reduce costs and improve the access to robotic surgery. The aim of the study is to compare direct cost for initial hospital stay of radical prostatectomy performed with two different robotic systems, the Da Vinci and the new Hugo RAS system. This is a projection study that applies cost of robotic surgery, derived from a local tender, to the clinical course of robotic radical prostatectomy (RALP) performed with Da Vinci and Hugo RAS. The study was performed in a public referral center for robotic surgery equipped with both systems. The cost of robotic surgery from a local tender were considered and included rent, annual maintenance, and a per-procedure fee covering the setup of four robotic instruments. Those costs were applied to patients who underwent RALP with both systems since November 2022. The primary endpoint is to evaluate direct costs of initial hospital stay for Da Vinci and Hugo RAS, by considering equipment costs (as derived from the tender), and costs of theater and of hospitalization. The direct per-procedure cost is €2,246.31 for a Da Vinci procedure and €1995 for a Hugo RALP. In the local setting, Hugo RAS provides 11% of cost saving for RALP. By applying this per-procedure cost to our clinical data, the expenditure for the entire index hospitalization is € 6.7755,1 for Da Vinci and € 6.637,15 for Hugo RALP. The new Hugo RAS system is willing to reduce direct expenditures of robotic surgery for RALP; furthermore, it provides similar peri-operative outcomes compared to the Da Vinci. However, other drivers of costs should be taken into account, such as the duration of OR use-that is more than just console time and may depend on the facility's background and organization. Further variations in direct costs of robotic systems are related to caseload, local agreements and negotiations. Thus, cost comparison of new robotic platform still remains an ongoing issue.

Robotic-Assisted Radical Cystectomy: Single-Center Analysis of Factors Impacting Clavien ≥ II Complications.

Despite the advent of robotics and the decreasing rate of complications after radical cystectomy, several factors are renowned to impair the early outcomes of this procedure. The aim of this paper is to provide a multivariate analysis (MVA) of patient and surgical procedure-related variables likely to affect postoperative course and 30-day complication rate. Fifty-five robotic-assisted radical cystectomies (RARCs) performed at a single center from July 2021 to March 2023 were enrolled. Baseline demographics, comorbidities, and intraoperative and postoperative data were collected. Uni- and multivariate analyses were performed to evaluate the relationship with Clavien ≥ II complications arising within 30 days of surgery. A postoperative Clavien ≥ II complication was evident in 15 patients (28%), whereas Clavien ≥ III occurred only in 5 (9%). At MVA, the only independent predictor of Clavien ≥ II complications was a prior neoadjuvant chemotherapy (OR 5.6; 95% CI 1.22-25.3, p = 0.026). Recognized the small sample size, patients who received a prior NAC should deserve special care within the postoperative course.

External validation of a nomogram for outcome prediction in management of medium-sized (1-2 cm) kidney stones.

BACKGROUND: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation. The aim of the present study is to externally validate the model to assess whether it displayed a satisfactory predictive performance if applied to different populations. METHODS: External validation was retrospectively performed on 3025 patients who underwent an active stone treatment from December 2010 to June 2021 in 26 centers from four countries (Italy, USA, Spain, Argentina). Collected variables included: age, gender, previous renal surgery, preoperative urine culture, hydronephrosis, stone side, site, density, skin-to-stone distance. Treatment failure was the defined outcome (residual fragments >4 mm at three months CT-scan). RESULTS: Model discrimination in external validation datasets showed an area under ROC curve of 0.66 (95% 0.59-0.68) with adequate calibration. The retrospective fashion of the study and the lack of generalizability of the tool towards populations from Asia, Africa or Oceania represent limitations of the current analysis. CONCLUSIONS: According to the current findings, Micali's nomogram can be used for treatment prediction after SWL, RIRS and PNL; however, a lower discrimination performance than the one at internal validation should be acknowledged, reflecting geographical, temporal and domain limitation of external validation studies. Further prospective evaluation is required to refine and improve the nomogram findings and to validate its clinical value.

Pre-operative prediction of extracapsular extension of prostate cancer: first external validation of the PRECE model on an independent dataset.

INTRODUCTION: The PRECE is a model predicting the risk of extracapsular extension (ECE) of prostate cancer: it has been developed on more than 6000 patients who underwent robotic radical prostatectomy (RARP) at the Global Robotic Institute, FL, USA. Up to now, it is the single tool predicting either the side and the amount of ECE. The model has a free user-friendly interface and is made up from simple and available covariates, namely age, PSA, cT, GS and percent of positive core, the latter topographically distributed within the prostate gland. Despite the successful performance at internal validation, the model is still lacking an external validation (EV). The aim of the paper is to externally validate the PRECE model on an Italian cohort of patients elected to RARP. METHODS: 269 prostatic lobes from 141 patients represented the validation dataset. The EV was performed with the receiver operating characteristics (ROC) curves and calibration, to address the ability of PRECE to discriminate between patients with or without ECE. RESULTS: Overall, an ECE was found in 91 out of the 269 prostatic lobes (34%). Twenty-five patients out of pT3 had a bilateral ECE. The ROC curve showed an AUC of 0.80 (95% CI 0.74-0.85). Sensitivity and specificity were 77% and 69%, respectively. The model showed an acceptable calibration with tendency towards overestimation. CONCLUSIONS: From the current EV, the PRECE displays a good predictive performance to discriminate between cases with and without ECE; despite preliminary, outcomes may support the generalizability of the model in dataset other than the development one.

Robot-Assisted Radical Cystectomy: A Single-Center Experience and a Narrative Review of Recent Evidence.

Radical cystectomy represents one of the most challenging surgical procedures, exhibiting a high morbidity rate. The transition to minimally invasive surgery in the field has been steep, due to either the technical complexity and prior concerns of atypical recurrences and/or peritoneal spread. More recently, a larger series of RCTs has proven the oncological safety of robot-assisted radical cystectomy (RARC). Beyond survival outcomes, the comparison between RARC and open surgery in terms of peri-operative morbidity is still ongoing. We present a single-center experience of RARC with intracorporeal urinary diversion. Overall, 50% of patients had an intracorporeal neobladder reconstruction. The series confirms a low rate of complications (Clavien Dindo ≥ IIIa 7.5%) and wound infections (2.5%) and the absence of thromboembolic events. No atypical recurrences were found. To discuss these outcomes, we reviewed the literature related to RARC including level-1 evidence. PubMed and Web of Science searches were performed using the medical subject terms "robotic radical cystectomy" and "randomized controlled trial (RCT)". Six unique RCTs comparing robot and open surgery were found. Two clinical trials dealt with RARC with an intracorporeal reconstruction of UD. Pertinent clinical outcomes are summarized and discussed. In conclusion, RARC is a complex but feasible procedure. The transition from extracorporeal urinary diversion (UD) to a complete intracorporeal reconstruction could be the key to improving peri-operative outcomes and reducing the whole morbidity of the procedure.

Digital real-time microscopy of ex-vivo tissues: A novel strategy to control surgical accuracy.

INTRODUCTION: Ex-vivo FCM is a novel digital optical technique that provides images of fresh tissues in a real-time fashion with magnification to subcellular details of a flattened unprocessed sample. Digital images are hematoxylin-eosin-like and can be shared and interpreted remotely. In urology, FCM has been successfully applied for prostate tissue interpretation, either during biopsy and radical prostatectomy. Possible applications of FCM may reflect those of frozen section analysis and can be extended to all fields in which the intra-operative microscopical control is advisable. MATERIALS AND METHODS: This is an investigative prospective case series that aims to explore FCM feasibility in novel surgical settings and provide a depiction of FCM digital images in those fields. The definite purpose is to check the accuracy of surgical specimen during the following interventions: (a) trans-urethral resection of bladder tumors, to confirm the presence of muscular layer; (b) biopsy of a retroperitoneal mass, to check for the location and quality of cores; (c) training in robotic radical prostatectomy, to control surgical margins after a nerve sparing performed by a trainee. To this aim, we collected FCM images during seven surgical procedures. FCM findings were compared to those from the final histopathological analysis and the agreement was assessed. RESULTS: In all cases, FCM digital images were obtained in the OR. FCM was able to confirm the presence of muscular layer in TURB specimen, the presence of lymphomatous tissue, surgical margins at prostate specimen. FCM intra-operative interpretation was consistent with final histopathology in all cases. CONCLUSIONS: Ex vivo FCM may represent a novel approach to control the quality of specimens, likely to tailor surgical strategy in a real-time fashion. Moreover, digitalization represents a step toward the implementation of telepathology in clinical practice.

First case of robot-assisted radical cystectomy and intracorporeal neobladder reconstruction with the Hugo RAS system: step-by-step surgical setup and technique.

Robotic assisted radical cystectomy (RARC) is a standard option for the treatment of bladder cancer. Currently, novel platforms are entering the market and the Hugo RAS (Medtronic, Minneapolis, MN, USA) is a new system consisting of an open console with 3D-HD screen and a multi-modular fashion. Even if several series are already available for radical prostatectomy, to now a full description of RARC performed with Hugo RAS is still lacking. We report the first case of RARC with intracorporeal neobladder performed with the Hugo RAS-and another case of RARC with ureterostomy. Both patients were affected by MIBC. Case 1 was a 61-year-old patient without comorbidities (CCI 4), in which a Bordeaux ileal neobladder was scheduled after previous NAC. The second was the case of a 70-year-old one with CCI 7 and BMI 35; in this case, a ureterostomy was planned. Details of the robotic system: one 11 mm endoscope port was placed on the midline 2 cm above the umbilicus. Another two 8 mm robotic ports were symmetrically placed under vision on a transversal line-located 1 cm below the umbilicus. A third robotic port was positioned on the left side in a W configuration. All ports were located at least 9 cm between each other. Finally, two assistant ports were positioned in the right abdominal site. All arm-carts were parked 45-60 cm from the operative bed, before the docking process begins. Three arm-carts were parked on the left side, the assistant and the scrub nurse worked on the right side, while the energy tower stayed at the foot of the bed, according to the previous description of Hugo RAS robotic radical prostatectomy. The endoscope arm-cart is docked first, then the adjacent left carts are docked; finally, the surgeon's right-hand cart is docked from the right side of the bed. The docking angles and tilt we applied were: endoscope: 175°; minus 45°; surgeon left hand 140°; minus 30°; surgeon right hand 225°; minus 30°; fourth arm 125°; plus 15°. The instruments we used were those fitting our conventional four-instrument setup for RARC: monopolar shears, Maryland forceps, needle driver and Cadiere as the fourth arm. The procedures were completed without technical errors or technological failures-requiring a change in surgical strategy. Docking time was approximately 35 min; console time up to urethral dissection was 150 and 140 min in Case 1 and 2. The time for pelvic nodal dissection was approximately 37 min for both. The multi-modularity fashion of the Hugo RAS allowed an easy management of the bowel in Case 1; the absence of robotic staplers required the use of the laparoscopic ones, managed by an adjunctive assistant with room within the cart. In conclusion, RARC with the Hugo RAS is a feasible procedure able to reproduce all surgical steps without critical errors or complications requiring a change in surgical planning. Urinary diversion with intracorporeal reconstruction is feasible as well, with adequate preliminary outcomes.

Multimodular robotic systems (Hugo RAS and Versius CMR) for pelvic surgery: tasks and perspectives from the bed-side assistant.

The Hugo RAS and Versius are new robotic systems with a multimodular configuration, requiring a dedicated positioning of units, arms and trocars. While promising flexibility and multiquadrant opportunities-with an enhanced range of motion-the presence of multiple units around the patient should be effectively managed by the assistant and requires a new background of tasks. The article represents a practical guide while providing an overview on assistants' perspectives.

Three-Dimensional Customized Imaging Reconstruction for Urological Surgery: Diffusion and Role in Real-Life Practice from an International Survey.

Despite the arising interest in three-dimensional (3D) reconstruction models from 2D imaging, their diffusion and perception among urologists have been scarcely explored. The aim of the study is to report the results of an international survey investigating the use of such tools among urologists of different backgrounds and origins. Beyond demographics, the survey explored the degree to which 3D models are perceived to improve surgical outcomes, the procedures mostly making use of them, the settings in which those tools are mostly applied, the surgical steps benefiting from 3D reconstructions and future perspectives of improvement. One hundred responders fully completed the survey. All levels of expertise were allowed; more than half (53%) were first surgeons, and 59% had already completed their training. Their main application was partial nephrectomy (85%), followed by radical nephrectomy and radical prostatectomy. Three-dimensional models are mostly used for preoperative planning (75%), intraoperative consultation and tailoring. More than half recognized that 3D models may highly improve surgical outcomes. Despite their recognized usefulness, 77% of responders use 3D models in less than 25% of their major operations due to costs or the extra time taken to perform the reconstruction. Technical improvements and a higher availability of the 3D models will further increase their role in surgical and clinical daily practice.

Prior Robotic Console Expertise May Improve Basic Skills at the New Hugo RAS Simulator: Results from a Cohort Trial and Implications for Skill Transference Across Platforms.

Background: Robot-assisted surgery ensures minimal invasiveness; since the expiry of the Da Vinci patent, new robotic systems have entered the market. Recently, the Hugo RAS received CE approval for several surgical procedures. However, more is needed to know about skill acquisition at the new simulator. Objective: This study aims to analyse the factors impacting basic surgical skills at the Hugo RAS simulator. Design setting and participants: We present a cross-sectional study involving 71 participants of different backgrounds invited to a hands-on session with the Hugo RAS simulator voluntarily. All of them had no prior expertise with the system. Participants were recruited among medical/nurse students, residents, and laparoscopic and robotic surgeons. Intervention: All participants underwent a hands-on "pick and place" exercise at the Hugo RAS simulator; the metrics of a second-round pick and place exercise were recorded. Outcome measurements and statistical analysis: Metrics were analysed with regard to the following variables: demographics, videogame use, and prior surgical experience (no surgical expertise, experience with laparoscopy, and experience with robotic console). Results and limitations: All participants completed the test. Of them, 77.5% were naïve to surgery, 8.5% had prior laparoscopic expertise, and 14.1% had prior robotic console experience. The time to complete the pick and place exercise was significantly lower (p < 0.001) among prior robotic surgeons (38 s, interquartile range [IQR] 34-45) compared with both naïve participants (61 s, IQR 53-71) and laparoscopists (93 s, IQR 53-162). The overall score of the exercise decreased with age (p = 0.046); however, the overall scores were significantly and steadily higher among surgeons experienced in robotic consoles across all age groups (p = 0.006). Neither gender (p = 0.7) nor videogame use (p = 0.9) correlated significantly with the metrics. Conclusions: This is the first study analysing factors impacting basic skill acquisition at a new robotic simulator. Experience with robotic consoles may represent a major factor, raising the hypothesis of the transferability of basic robotic skills across different robotic systems. Further studies are required to explore this issue. Patient summary: In the present study, we analysed which characteristics may affect the basic surgical skills at a novel robotic platform.

Impact of hands-on practice with HugoRAS and Versius System simulators on the attractiveness of robotic surgery among medical and nurse undergraduate students.

The scenario of robotic surgery is rapidly evolving with the introduction of new robotic systems. A structured learning program in robotic surgery during academic education is often lacking, especially for undergraduates; as a result, many students may be unaware of indications to robotic surgery and technological progress. The aim of the study is to evaluate the knowledge and interest toward robotic surgery of medical and nurse students, and to analyze how the attractiveness may change after a hand-on training course with new simulators of Hugo RAS and Versius System. We performed a cross-sectional study involving medical and nurse students recruited on a voluntary basis at ASST Santi Paolo and Carlo, Milan; participants were invited to join a hands-on practice simulation with the Hugo RAS and/or Versius Trainer Simulator. Before the hand-on exercise, students were asked to fulfill an online anonymous questionnaire addressing knowledge and interest toward robotic surgery. After a 2-h hands-on exercises at the Hugo RAS and/or at the Versius Trainer simulator (preceded by a brief lecture on robotic surgery and new systems), participants were asked to complete a second-round questionnaire to evaluate changes in attractiveness toward robotic surgery. Data were recorded in a database; after a descriptive analysis of the variables, median values were compared with the Mann-Whitney U test, frequencies with the Fisher's exact test and in the case of paired observations (before and after the simulation), the Mc Nemar test was used. Forty-one undergraduates agreed to participate. Twenty-three nursing students and 18 medical students were recruited. Some of them had a basic knowledge in robotic surgery and were able to figure out some surgical indications, given the presence of a robotic program already settled up at the institution. Before the hands-on course, 44.0% nurse students and 36.6% of medical students were interested in surgical disciplines and robotic surgery. After the simulation, all students (100%) reported a high level of interest in robotic surgery and some of them required for a dedicated internship (p < 0.001). The students provided also feedback on the perceived ease-of-use of the robotic simulators (on a scale 0-10); overall, the median score was 8, IQR [7-8], with no differences between nursing and medical students (p = 0.482). In conclusion, the study demonstrates a great interest toward robotic surgery as a part of medical and nurse education. A hands-on simulation further improved the interest of undergraduates from both backgrounds. The technological progress with the availability of new surgical systems will be the future challenge of training programs and should be considered at all levels of education.

Pelvic lymph node dissection in prostate and bladder cancers.

Prostate cancer and bladder cancer accounts for approximately 13.5% and 3% of all male cancers and all newly diagnosed cancers (regardless sex), respectively. Thus, these cancers represent a major health and economic burden globally. The knowledge of lymph node status is an integral part of the management of any solid tumor. In the urological field, pelvic lymph node dissection (PLND) is of paramount importance in the diagnosis, management, and prognosis of prostate and bladder cancers. However, PLND may be associated with several comorbidities. In this narrative review, the most recent updates concerning the patterns and incidence of lymph node metastasis, the role of different imaging studies and nomograms in determining patients' eligibility for PLND, and the anatomical templates of PLND in urologic patients with bladder or prostate cancer will be discussed.

May Outcomes of Robotic Radical Prostatectomy Performed After an Initial Surveillance Strategy Differ from Those from Immediate Surgery? A Propensity Score-Matched Analysis on 362 Patients Undergoing Surgery at a Referral Center.

Introduction: Active surveillance (AS) is a treatment strategy for low-risk prostate cancer (PCa) patients, with extended indication to some intermediate-risk PCa. However, active treatment is necessary in case of disease progression and robotic radical prostatectomy (RALP) is one of the treatment modalities. The aim of the study is to compare outcomes of a delayed RALP after an initial heterogeneous surveillance strategy with those of immediate RALP in a single referral center. Methods: Data from patients who underwent RALP after initial assumed "active surveillance" (referred from different institutions and backgrounds) were compared to those of patients who underwent an immediate RALP after propensity score (PS) matching. The PS analysis was performed matching ISUP score at the time of entering surveillance with ISUP at RALP for the control group; other matching covariates at the time of surgery were considered (including age, prostate-specific antigen, body mass index, prostate size, cT, pre-op Sexual Health Inventory for Men, etc.). Perioperative, functional, and oncological outcomes were compared between groups. Results: Three hundred sixty-two RALP patients were included (181 after surveillance and 181 immediate RALP). Patients after surveillance had a worse pT and ISUP score (p < 0.001); LVI and EPE were higher in the surveilled group (13% vs. 5%, p = 0.001; 38% vs. 22%, p = 0.001), without significant difference in positive surgical margin. At a median follow-up of 24 months, the risk of biochemical recurrence (BCR) was significantly higher for delayed RALP (hazard ratio: 4.0; 95% confidence interval: 1.4-12; p = 0.013), whereas potency and continence rate did not differ significantly. Conclusions: At a referral center receiving patients from diverse backgrounds, outcomes of RALP after heterogeneous surveillance strategies are variable and less predictable, maybe attributable to different protocols and surgical planning. The higher BCR rate in a high-risk surveilled cohort may suggest an increased burden of cancer-related care for RALP patients after surveillance.

Low-intensity Extracorporeal Shockwave Therapy for the Management of Postprostatectomy Erectile Dysfunction: A Systematic Review of the Literature.

Context: Erectile dysfunction (ED) following radical prostatectomy is a concern for patients and their partners. Low-intensity extracorporeal shockwave therapy (LI-ESWT) can potentially enhance tissue repair and regeneration. The aim of the current study was to systematically review the literature to assess the role of LI-ESWT in the management of patients with postprostatectomy ED. Evidence acquisition: Two authors independently performed a systematic search of the PubMed and Web of Science databases to identify all relevant articles. Non-English reports, case reports, reviews, letters, and editorials were excluded. Risk of bias was assessed according to the GRADE guidelines. Evidence synthesis: Nine articles met the inclusion criteria and were included in the qualitative analysis. All the studies included were published between 2015 and 2022 and the majority of them compared phosphodiesterase type 5 inhibitors (PDE5Is) alone versus a combination of LI-ESWT and PDE5Is. Only three studies were randomized controlled trials (RCTs). In general, there is no standardized protocol for LI-ESWT for postprostatectomy ED. In comparisons of LI-ESWT + PDE5Is versus PDE5Is alone, some authors found a statistically significant improvement in erectile function with LI-ESWT + PDE5Is. The starting time for LI-ESWT differed among the studies, ranging from 3 d to 6 mo after surgery. The main limitations of the review are the scarcity of studies, small sample sizes, high risk of bias, and high heterogeneity among studies. Conclusions: There is currently limited evidence on the use of LI-ESWT either alone or in combination with PDE5Is in penile rehabilitation protocols after prostatectomy. However, small clinical trials with short follow-up show that LI-ESWT could potentially play a role in the management of postprostatectomy ED in the future. Further RCTs with larger sample sizes are needed. Patient summary: Despite limited reports in the literature, low-intensity shockwave therapy after removal of the prostate is a promising noninvasive treatment for dealing with erectile dysfunction after surgery.

Psychological distress among patients awaiting histopathologic results after prostate biopsy: An unaddressed concern.

BACKGROUND: Prostate cancer is the most commonly diagnosed neoplasm in men. From the introduction of PSA testing, an increasing number of men undergoes prostate biopsy (PBX). While the physical side effects of PBx have been well investigated, its psychological impact has been under-evaluated. AIM: The aim of our study is to investigate the presence of psychological distress (anxiety and depression) in patients waiting for histopathological results after prostate biopsy (PBx). METHODS: From February to April 2019, 51 consecutive patients undergoing prostate biopsies at our institution were included. Age, PSA, DRE, familiarity for prostate cancer, number of previous biopsies, type of anesthesia, number of cores were recorded. All patients filled the Hospital Anxiety and Depression Scale (HADS), a psychometric Likert-scale questionnaire, before receiving the histopathological results of their PBx. RESULTS: The prevalence of psychological distress among patients awaiting histopathologic results is 41% (21/51 patients), with anxiety being the main component of their distress. On multivariate analysis, PSA, family history, and repeat biopsy were significantly associated with anxiety and depression. CONCLUSION: Patients undergoing PBx experience a burden of psychological distress waiting for histopathologic results, especially anxiety. Appropriate counseling should be offered to patients at high risk of developing psychological distress after PBx. Future goals would include technological improvements to shorten the time between biopsy and definitive results.

Current and future perspectives of digital microscopy with fluorescence confocal microscope for prostate tissue interpretation: a narrative review.

Fluorescence confocal microscopy (FCM) is an optical imaging technique providing digital microscopical images of fresh tissue in a real time fashion, without conventional processing. FCM has been widely applied in several fields of dermatology, including the detection of basal cell carcinoma and of cutaneous inflammatory diseases. The aim of the paper is to provide an overview of FCM applications in the field of prostate tissue interpretation and prostate cancer (PCa) detection. A Literature search (PubMed & Web of Science) was performed to identify articles concerned with the clinical and surgical applications of FCM in prostatic and periprostatic tissues interpretation. Overall, six articles were identified. All articles investigated the level of agreement between FCM and conventional histopathological analysis (hematoxylin-eosin, HE) for the discrimination between normal and PCa tissues. An investigative article on prostate samples retrieved from radical prostatectomy (RP) specimens and an atlas of FCM digital images from the same series were found. Two prospective clinical trials, comparing FCM and HE, pointed out a "substantial" to "almost perfect" discriminative performance of FCM for the diagnosis of PCa on prostate biopsy core. Finally, two studies investigated the intra-operative role of FCM during RP for the control of surgical dissection. In this setting, FCM could be used to analyse samples retrieved from suspicious peri-prostatic areas; FCM has also been tested for an en-face evaluation of flat slices obtained from the systematic sampling of the posterolateral aspects of the prostate, in a NeuroSAFE-like approach. Generally, FCM provides digital microscopical images of fresh tissue in a real time fashion, without requiring conventional processing. Currently, available studies confirmed a high concordance with conventional pathology for the detection of PCa. Further studies are required to validate the technology, to evaluate ISUP score attribution and to implement the fields of application of FCM for the treatment of prostate diseases.
