Follow-up on patients with initial negative mpMRI target and systematic biopsy for PI-RADS ≥ 3 lesions - an EAU-YAU study enhancing prostate cancer detection.

PURPOSE: To investigate the detection and predictors of prostate cancer (PCA) and clinically significant prostate cancer (csPCA) in patients with positive multiparametric MRI (mpMRI) followed by a negative MRI - guided target biopsy (TB) and systematic biopsy (SB). MATERIALS AND METHODS: This retrospective multicenter study included 694 patients from 10 tertiary referral centers with an initial positive mpMRI (PI-RADS ≥ 3) and negative results on both MRI-TB and SB. Patients were classified into three groups based on follow-up: Group 1 (prostate re-biopsy without new mpMRI), Group 2 (standardized second prostate mpMRI and subsequent re-biopsy), and Group 3 (follow-up with mpMRIs and biopsy based on clinical and radiological triggers). The primary outcomes were the detection of any PCA and csPCA during follow up. Study groups were compared according to their probability of PCA and csPCA assessed with the ERSPC-MRI risk calculator. Statistical analysis included Kaplan - Meier analysis, Cox regression, and multivariable analysis for the detection of (cs)PCa. RESULTS: The overall detection of PCA and csPCA was 26.8% and 19.3%, respectively, with varying rates in different PI-RADS groups. Group 3 had the highest 2-year and 5-year PCA-free survival (94 and 84%) and csPCA - free survival (96 and 86%). Multivariable analysis revealed a significantly higher risk of PCA and csPCA in Group 1 and 2 compared to Group 3 (p < 0.01). Clinical and radiological predictors for PCA and csPCA included higher age, prostate volume, PI-RADS score, the presence of atypical small acinar proliferation (ASAP), and a smaller number of TB and SB performed during the initial biopsy. Study limitations, include the retrospective design and reliance on clinical and radiological triggers for follow-up decisions. CONCLUSIONS: Patients with positive mpMRI but negative TB and SB results exhibit varying rates of PCA and csPCA depending on the follow up scheme. Tailored follow-up strategies are essential for optimal management in this clinical scenario.

PSMA PET-targeted Biopsy for Prostate Cancer Diagnosis: Initial Experience From a Multicenter Cohort.

OBJECTIVE: To describe the initial experience with PSMA-PET/CT-guided biopsy in European referral centres. METHODS: This multicenter observational cohort study was endorsed by the Young Academic Urologist (YAU) Prostate Cancer Group of the EAU and conducted across 6 tertiary-level European centres. PSMA-guided biopsies were carried out in a cognitive/fusion manner for all the recruited patients with or without MRI-guided biopsies and/or standard biopsy (SB). PCa and clinical significant PCa (csPCA) detection rate (DR) at prostate biopsy was assessed. Uni- and multivariable models were employed to identify features related to csPCA. RESULTS: Overall, 72 patients were recruited. The topographic location of the dominant lesion depicted by PSMA PET/CT was significantly associated with the location of csPCa, especially in the biopsy naïve cohort. The DR for PCa and csPCa of PSMA-PET/CT-guided biopsies was significantly higher than SB (0.40 ± 0.43 vs 0.23 ± 0.29, and 0.36 ± 0.44 vs 0.21 ± 0.30, respectively, both P <.05) but did not surpass MRI-guided biopsies (0.40 ± 0.43 vs 0.47 ± 0.44, and 0.36 ± 0.44 vs 0.47 ± 0.34, respectively, both P >.05). PSMA-PET/CT-guided biopsy performed better in the biopsy naïve than in the repeated biopsy setting. A SUVmax cut-off value equal to 4.8 provided the best results for detecting csPCa. CONCLUSION: Our real-world data illustrate the potentialities of PSMA-PET/CT-guided biopsy in diagnosing PCa. Specifically, in biopsy naïve patients with suspicion of high-risk disease, the use of PSMA-PET/CT-targeted biopsy can be considered. Additionally, in the context of repeated biopsies, a PSMA-PET/CT target biopsy might be advisable over the SB.

Oncologic Outcomes of Incidental Versus Biopsy-diagnosed Grade Group 1 Prostate Cancer: A Multi-institutional Study.

Background and objective: Patients diagnosed with grade group (GG) 1 prostate cancer (PCa) following treatment for benign disease ("incidental" PCa) are typically managed with active surveillance (AS). It is not known how their outcomes compare with those observed in patients diagnosed with GG1 on biopsy. We aimed at determining whether long-term oncologic outcomes of AS for patients with GG1 PCa differ according to the type of diagnosis: incidental versus biopsy detected. Methods: A retrospective, multi-institutional analysis of PCa patients with GG1 on AS at eight institutions was conducted. Competing risk analyses estimated the incidence of metastases, PCa mortality, and conversion to treatment. As a secondary analysis, we estimated the risk of GG ≥2 on the first follow-up biopsy according to the type of initial diagnosis. Key findings and limitations: A total of 213 versus 1900 patients with incidental versus biopsy-diagnosed GG1 were identified. Patients with incidental cancers were followed with repeated biopsies and multiparametric magnetic resonance imaging less frequently than those diagnosed on biopsy. The 10-yr incidence of treatment was 22% for incidental cancers versus 53% for biopsy (subdistribution hazard ratio [sHR] 0.34, 95% confidence interval [CI] 0.26-0.46, p < 0.001). Distant metastases developed in one patient with incidental cancer versus 17 diagnosed on biopsy and were diagnosed with molecular imaging in 13 (72%) patients. The 10-yr incidence of metastases was 0.8% for patients with incidental PCa and 2% for those diagnosed on biopsy (sHR 0.35, 95% CI 0.05-2.54, p = 0.3). The risk of GG ≥2 on the first follow-up biopsy was low if the initial diagnosis was incidental (7% vs 22%, p < 0.001). Conclusions and clinical implications: Patients with GG1 incidental PCa should be evaluated further to exclude aggressive disease, preferably with a biopsy. If no cancer is found on biopsy, then they should receive the same follow-up of a patient with a negative biopsy. Further research should confirm whether imaging and biopsies can be avoided if postoperative prostate-specific antigen is low (<1-2 ng/ml). Patient summary: We compared the outcomes of patients with low-grade prostate cancer on active surveillance according to the type of their initial diagnosis. Patients who have low-grade cancer diagnosed on a procedure to relieve urinary symptoms (incidental prostate cancer) are followed less intensively and undergo curative-intended treatment less frequently. We also found that patients with incidental prostate cancer are more likely to have no cancer on their first follow-up biopsy than patients who have low-grade cancer initially diagnosed on a biopsy. These patients have a more favorable prognosis than their biopsy-detected counterparts and should be managed the same way as patients with negative biopsies if they undergo a subsequent biopsy that shows no cancer.

Observation With or Without Subsequent Salvage Therapy for Pathologically Node-positive Prostate Cancer With Negative Conventional Imaging: Results From a Large Multicenter Cohort.

Background and objective: More than 10% of patients with negative clinical metastatic status (cN0M0) on conventional imaging for prostate cancer (PCa) harbor lymph node involvement (pN+) at final pathology following radical prostatectomy (RP) and lymphadenectomy. Our aim was to assess outcomes of initial observation for cN0M0 pN+ PCa and identify prognostic factors that may help in clinical decision-making. Methods: We performed a retrospective multicenter study of patients with cN0M0 PCa on conventional imaging (computed tomography and/or magnetic resonance imaging, and a bone scan) who were found to have pN+ disease at RP between 2000 and 2021. Biochemical recurrence (BCR) and systemic progression/recurrence were the primary outcomes. Kaplan-Meier curves and Cox proportional hazards model were used for survival and multivariate analysis. Key findings and limitations: A total of 469 men were included in this retrospective multicenter trial. Median prostate-specific antigen (PSA) was 10.1 ng/ml (interquartile range [IQR] 6.6-18.0). Among these patients, 56% had grade group ≥4, 53.7% had stage ≥pT3b, 42.6% had positive margins, and 19.6% had PSA persistence. The median number of positive nodes and of nodes removed were 1 (IQR 1-3) and 20 (14-28), respectively. At median follow-up of 41 mo, 48.5% experienced BCR. The 5-yr BCR-free survival rate was 31.7% (95% confidence interval [CI] 26.33-37.1%). Salvage treatments were needed in 211 patients and included radiotherapy (RT; n = 53), RT + androgen deprivation therapy (ADT; n = 88), ADT alone (n = 68), and salvage lymphadenectomy (n = 2). The 5-yr estimated survival rates were 66.3% (95% CI 60.4-72.1) for metastasis-free survival, 97.7% (95% CI 95.5-99.8%) for cancer-specific survival, and 95.3% (95% CI 92.4-98.1%) for overall survival. On multivariable analysis, PSA persistence was an independent predictor of BCR (odds ratio [OR] 51.8, 95% CI 12.2-219.2), exit from observation (OR 8.5, 95% CI 4.4-16.5), and systemic progression (OR 3.0, 95% CI 1.771-4.971). Conclusions: Initial observation in the management of pN+ cN0M0 PCa is feasible and has excellent survival rates in the intermediate term. Patients with worse disease features, especially PSA persistence, have a higher likelihood of recurrence and progression and may be candidates for more aggressive upfront management. Patient summary: We investigated the value of initial observation for men with prostate cancer with negative scan findings for metastasis who were then found to have positive lymph nodes after surgery to remove the prostate. Our results show that initial observation is a good option for patients with less aggressive prostate cancer features.

Transperineal Versus Transrectal Magnetic Resonance Imaging-targeted Prostate Biopsy: A Systematic Review and Meta-analysis of Prospective Studies.

BACKGROUND AND OBJECTIVE: The benefits of the detection of clinically significant prostate cancer (csPCa) and safety of magnetic resonance imaging (MRI)-targeted transperineal (TP) prostate biopsy (TP-Tbx) versus transrectal (TR) approaches are still a matter of debate. This review aims to compare the efficacy and safety of TP-Tbx and MRI-targeted TR biopsy (TR-Tbx). METHODS: A systematic literature search was performed in PubMed/Medline, Scopus, and Web of Science to identify records of prospective randomized controlled trials (RCTs) comparing TP-Tbx and TR-Tbx published until May 2024. The primary outcomes included detection rates of csPCa (International Society of Urological Pathology [ISUP] ≥2) and rates of complications. KEY FINDINGS AND LIMITATIONS: Three RCTs (PREVENT, ProBE-PC, and PERFECT) met the inclusion criteria. The TR technique was commonly administered with antibiotic prophylaxis to mitigate infection risks or after a rectal swab. No difference was found between TP-Tbx and TR-Tbx in terms of either csPCa (odds ratio [OR] 0.9, 95% confidence interval [CI]: 0.7-1.1) or ISUP 1 prostate cancer (PCa; OR 1.1, 95% CI: 0.8-1.4) detection. Postprocedural infection (OR 0.8, 95% CI: 0.4-1.8), sepsis (OR 0.6, 95% CI: 0.1-4.5), and urinary retention rates (OR 0.5, 95% CI: 0.1-1.6) were similar. Pain during the TP approach was slightly higher than during the TR approach, but after 7 d of follow-up, the differences between the two approaches were minimal. Variations in biopsy numbers per patient, patient selection, use of 5-alpha reductase inhibitors, needle sizes, TP techniques, and pain scores (reported in only one RCT), along with the multicenter nature of RCTs, limit the study. CONCLUSIONS AND CLINICAL IMPLICATIONS: TP-Tbx and TR-Tbx show similar results in detecting PCa, with comparable rates of infections, urinary retention, and effectiveness in managing biopsy-associated pain. TP-Tbx can safely omit antibiotics without increasing infection risk, unlike TR-Tbx. The tendency to exclude from practice TR-Tbx with prophylactic antibiotics due to infection concerns could be moderated; however, the directionality of some key outcomes, as infections and sepsis, favor the TP approach despite a lack of statistical significance. PATIENT SUMMARY: There were no significant differences in the prostate biopsy approaches (transperineal [TP] vs transrectal [TR]) for prostate cancer detection and complications. However, the MRI-targeted TP prostate biopsy approach may be advantageous as it can be performed safely without antibiotics, potentially reducing antibiotic resistance.

Employing the Aviation Model to Reduce Errors in Robotic Gynecological Surgery: A Narrative Review.

The operating room is the environment where harm to the patient is most likely. Robotic surgery was listed as one of the top 10 health hazards as late as 2020. Taking inspiration from other fields of application, such as aeronautics, checklists have been increasingly implemented in medical practice over the years, becoming essential components of the operating theatre. In addition to checklists, simulation has taken on a fundamental importance in reducing errors. This paper aims to provide a narrative review to assess the importance of checklists and training in robotic surgery and how they improve the outcome. A comprehensive literature search from January 2000 to September 2023 was conducted. A total of 97 articles were included in the initial search. Eleven studies were deemed relevant and were considered eligible for full-text reading. Among these, ten studies focused on the analysis of training effectiveness. An article in our review assessed the benefits of introducing checklists in the operating room. Innovations created in aviation, such as checklists and simulation, have entered the medical field to prevent human error. Developing dedicated checklist and surgical teams, through theoretical and practical training, has become essential in modern medicine. Tools such as checklists, training, and simulation are among the best methods to reduce adverse medical events.

Treatment and Staging Intensification Strategies Associated with Radical Prostatectomy for High-Risk Prostate Cancer: Efficacy Evaluation and Exploration of Novel Approaches.

The management of high-risk prostate cancer (PCa) presents a significant clinical challenge, often necessitating treatment intensification due to the potential presence of micrometastases. While radical prostatectomy (RP) constitutes one of the primary treatment modalities, the integration of neoadjuvant and adjuvant therapies suggests a paradigm shift towards more aggressive treatment strategies, also guided by new imaging modalities like positron emission tomography using prostate-specific membrane antigen (PSMA-PET). Despite the benefits, treatment intensification raises concerns regarding increased side effects. This review synthesizes the latest evidence on perioperative treatment intensification and de-escalation for high-risk localized and locally advanced PCa patients eligible for surgery. Through a non-systematic literature review conducted via PubMed, Scopus, Web of Science, and ClinicalTrials.gov, we explored various dimensions of perioperative treatments, including neoadjuvant systemic therapies, adjuvant therapies, and the role of novel diagnostic technologies. Emerging evidence provides more support for neoadjuvant systemic therapies. Preliminary results from studies suggest the potential for treatments traditionally reserved for metastatic PCa to show apparent benefit in a non-metastatic setting. The role of adjuvant treatments remains debated, particularly the use of androgen deprivation therapy (ADT) and adjuvant radiotherapy in patients at higher risk of biochemical recurrence. The potential role of radio-guided PSMA lymph node dissection emerges as a cutting-edge approach, offering a targeted method for eradicating disease with greater precision. Innovations such as artificial intelligence and machine learning are potential game-changers, offering new avenues for personalized treatment and improved prognostication. The intensification of surgical treatment in high-risk PCa patients is a dynamic and evolving field, underscored by the integration of traditional and novel therapeutic approaches. As evidence continues to emerge, these strategies will refine patient selection, enhance treatment efficacy, and mitigate the risk of progression, although with an attentive consideration of the associated side effects.

Short-term effects of bowel function on global health quality of life after radical cystectomy.

BACKGROUND: Radical cystectomy (RC) shows an important impact on quality of life (QoL), for various clinical aspects. The aim of our study was to evaluate the short-term bowel function in patients that underwent RC. METHODS: Two hundred and six patients with MIBC underwent RC with ONB or IC urinary diversion. QoL was measured using the EORTC QLQ C30 and the Short-Form SF-36 questionnaires before surgery and at 12 months postoperatively. Baseline characteristics, including demographic profile, BMI, Charlson Comorbidity Index (CCI), modified Frailty Index (m-FI), pathological tumor stage, Clavien-Dindo grade, and neo-adjuvant chemotherapy were recorded and compared. RESULTS: The uni-variate and multivariate analysis (OR) were performed for constipation, diarrhea and m-FI of patients underwent RC for localized MIBC according to global health status score (poor/good vs. very good). Multivariate analysis showed that constipation medium/high was significant associated with global health status poor/good (OR=2.39; 95% CI: 1.22-4.71; P=0.01); Diarrhea medium/high was associated with global health status poor/good (OR=2.85; 95% CI:1.18-6.92; P=0.02), and m-FI ≥2 score (OR=2.13; 95% CI: 0.99-4.57; P=0.05). CONCLUSIONS: Diarrhea and constipation are associated with a lower QoL in cystectomized patients, both with ONB or IC urinary diversion; such association is especially significant in more fragile patients (Frailty Index ≥2).

Retzius-sparing Robot-assisted Simple Prostatectomy: Perioperative and Short-term Functional Outcomes Assessed via Validated Questionnaires.

Background and objective: Several surgical procedures have been reported for treatment of male patients with lower urinary tract symptoms (LUTS) secondary to large benign outlet obstruction (BOO). The diffusion of robotic surgery offers the possibility to perform open simple prostatectomy (SP) with a minimally-invasive approach. Our aim was to report outcomes of the Retzius-sparing robot-assisted SP (RS-RASP) technique. Methods: This was a single centre, prospective study. Patients with LUTS secondary to BOO and a prostate volume of >100 ml underwent RS-RASP performed with a da Vinci surgical system in four-arm configuration for a transperitoneal approach. Data for intraoperative and perioperative complications were collected. Functional outcomes were assessed via validated patient questionnaires. Univariable and multivariable regression analyses were used to identify predictors of complications and achievement of a trifecta composite outcome. Key findings and limitations: The median patient age was 69 yr and the median prostate volume was 150 ml. The median operative time was 175 min, with estimated blood loss of 350 ml. The median in-hospital stay and median catheterisation time were 3 d and 9 d, respectively. Within 90 d, the incidence of complications was 3% for grade 1, 19% for grade 2, and 2% for grade 3 complications. At 7-mo follow-up, statistically significant improvements in International Prostate Symptom Scores (total score and quality of life), International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) scores, and the maximum flow rate were observed (all p < 0.0001). According to ICIQ-UI SF scores, 20%, 6%, and 3% of the patients had slight, moderate, or severe urinary incontinence (UI), respectively. Urgency UI was experienced by 14% of the patients and stress UI by 10%. Most of the patients with UI reported leakage of a small amount of urine and they did not wear pads. Conclusions: RS-RASP was associated with good perioperative outcomes and a low prevalence of high-grade complications. Significant LUTS relief was achieved, but some patients experienced slight urgency or stress UI at short-term follow-up. Patient summary: We explored a surgical technique called Retzius-sparing robot-assisted simple prostatectomy to treat men with bothersome urinary symptoms caused by a large prostate. The technique led to good results, with minimal bleeding and few complications during surgery. This surgery could be a beneficial choice for patients with stubborn urinary symptoms and a large prostate gland.

Conservative treatment of Peyronie's disease: a guide.

PURPOSE: To review the literature on the topic, to suggest a common line of treatment applicable across a wide community of specialists, and to contribute in maintaining the high level of interest in this disease. METHODS: A comprehensive and exhaustive review of the literature was performed, identifying hundreds of articles on the topic. RESULTS: Peyronie's disease is a condition that has been recognized, studied, and treated for centuries; despite this, if one excludes surgery in cases in which the deformity is stable, no clear treatment (or line of treatment) is available for complete relief of signs and symptoms. Treatment options were divided into local, oral, and injection therapy, and a wide variety of drugs, remedies, and options were identified. CONCLUSIONS: Low-intensity extracorporeal shock wave therapy, vacuum therapy, penile traction therapy, phosphodiesterase type 5 inhibitors, hyaluronic acid, and collagenase of Clostridium histolyticum may be recommended only in specific contexts. Further studies on individual options or potential combinations are required.

Laparoscopic intracorporeal ileal ureter replacement: multi-institutional data from 102 patients.

OBJECTIVE: To present long-term results of our laparoscopic intracorporeal ileal ureter replacement (LIUR) cohort, including more complex cases of laparoscopic ileocalycostomy. MATERIAL AND METHODS: We collected records of patients undergoing LIUR. Follow-up included a chemical profile and urine cultures. Imaging consisted of renal ultrasonography, excretory urography, cystography, and computer tomographic or magnetic resonance urography. RESULTS: One hundred and two patients were included. Stricture location was left (46.1%), right (39.2%), or bilateral (14.7%). No open conversion was performed. Seventy-four patients (72.5%) underwent a total ureteral unit removal. The mean operative time was 289.4 (120 - 680) minutes. The estimated blood loss was 185.2 (10-400) mL. Three patients had intraoperative complications, and fifteen had early postoperative complications. The mean postoperative hospital stay was 12.2 (7-35) days. The mean follow-up duration period was 37.7 (12-162) months. Most patients' follow-up was uneventful (88%), and seven patients presented with Grade 2 late complications. CONCLUSIONS: Intracorporeal laparoscopic ileal ureteral replacement in cases of extensive ureteral lesions offers optimal long-term outcomes and a low complication rate. Ileocalycostomy constitutes a viable option in the small group of patients with long proximal ureteral strictures and intrarenal pelvis.

Role of targeted biopsy, perilesional biopsy, random biopsy, and their combination in the detection of clinically significant prostate cancer by mpMRI/transrectal ultrasonography fusion biopsy in confirmatory biopsy during active surveillance program.

BACKGROUND: Based on the findings of different trials in biopsy naïve patients, target biopsy (TB) plus random biopsy (RB) during mpMRI-guided transrectal ultrasound fusion biopsy (FB) are often also adopted for the biopsy performed during active surveillance (AS) programs. At the moment, a clear consensus on the extent and modalities of the procedure is lacking. OBJECTIVE: To evaluate the increase in diagnostic accuracy achieved by perilesional biopsy (PL) and different RB schemes during FB performed in AS protocol. DESIGN, SETTING, AND PARTICIPANTS: We collected prospectively the data of 112 consecutive patients with low- or very-low-risk prostate cancer; positive mpMRI underwent biopsy at a single academic institution in the context of an AS protocol. INTERVENTION(S): mpMRI/transrectal US FB with Hitachi RVS system with 3 TB and concurrent transrectal 24-core RB. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The diagnostic yield of the different possible biopsy schemes (TB only; TB + 4 perilesional (PL) cores; TB + 12-core RB; TB + 24-core RB) was compared by the McNemar test. Univariable and multivariable regression analyses were adopted to identify predictors of any cancer, Gleason grade group (GGG) ≥2 cancers, and the presence of GGG≥2 cancers in the larger schemes only. RESULTS AND LIMITATIONS: The detection rate of GGG ≥2 cancers increased to 30%, 39%, and 49% by adding 4 PL cores, 14, and 24 RB cores, respectively, to TB cores (all p values <0.01). On the whole, TB alone, 14-core RB, and 24-core-RB identified 38%, 47%, and 56% of all the GGG ≥2 cancers. Such figures increased to 62% by adding to TB 4 PL cores, and to 80% by adding 14 RB cores. Most of the differences were observed in PI-RADS 4 lesions. CONCLUSIONS: We found that PL biopsy increased the detection rate of GGG ≥2 cancers as compared with TB alone. However, the combination of those cores missed a large percentage of the CS cancers identified with larger RB cores, including a 20% of CS cancers diagnosed only by the combination of TB plus 24-core RB.

Which Patients with Prostate Cancer and Lymph Node Uptake at Preoperative Prostate-specific Membrane Antigen Positron Emission Tomography/Computerized Tomography Scan Are at a Higher Risk of Prostate-specific Antigen Persistence After Radical Prostatectomy? Identifying Indicators of Systemic Disease by Integrating Clinical, Magnetic Resonance Imaging, and Functional Imaging Parameters.

BACKGROUND: The role of local therapies including radical prostatectomy (RP) in prostate cancer (PCa) patients with clinical lymphadenopathies on prostate-specific membrane antigen (PSMA) positron emission tomography/computerized tomography (PET/CT) has scarcely been explored. Limited data are available to identify men who would benefit from RP; on the contrary, those more likely to benefit already have systemic disease. OBJECTIVE: We aimed to assess the predictors of prostate-specific antigen (PSA) persistence in surgically managed PCa patients with lymphadenopathies on a PSMA PET/CT scan by integrating clinical, magnetic resonance imaging (MRI), and PSMA PET/CT parameters. DESIGN, SETTING, AND PARTICIPANTS: We identified 519 patients treated with RP and extended lymph node dissection, and who received preoperative PSMA PET between 2017 and 2022 in nine referral centers. Among them, we selected 88 patients with nodal uptake at preoperative PSMA PET (miTxN1M0). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The outcome was PSA persistence, defined as a PSA value of ≥0.1 ng/ml at the first measurement after surgery. Multivariable logistic regression models tested the predictors of PSA persistence. Covariates consisted of biopsy International Society of Urological Pathology (ISUP) grade group, clinical stage at MRI, and number of positive spots at a PET/CT scan. A regression tree analysis stratified patients into risk groups based on preoperative characteristics. RESULTS AND LIMITATIONS: Overall, lymph node invasion (LNI) was detected in 63 patients (72%) and 32 (36%) experienced PSA persistence after RP. At multivariable analyses, having more than two lymph nodal positive findings at PSMA PET, seminal vesicle invasion (SVI) at MRI, and ISUP grade group >3 at biopsy were independent predictors of PSA persistence (all p < 0.05). At the regression tree analysis, patients were stratified in four risk groups according to biopsy ISUP grade, number of positive findings at PET/CT, and clinical stage at MRI. The model depicted good discrimination at internal validation (area under the curve 78%). CONCLUSIONS: One out of three miN1M0 patients showed PSA persistence after surgery. Patients with ISUP grade 2-3, as well as patients with organ-confined disease at MRI and a single or two positive nodal findings at PET are those in whom RP may achieve the best oncological outcomes in the context of a multimodal approach. Conversely, patients with a high ISUP grade and extracapsular extension or SVI or more than two spots at PSMA PET should be considered as potentially affected by systemic disease upfront. PATIENT SUMMARY: Our novel and straightforward risk classification integrates currently available preoperative risk tools and should, therefore, assist physician in preoperative counseling of men candidates for radical treatment for prostate cancer with positive lymph node uptake at prostate-specific membrane antigen positron emission tomography.

Outcomes of Cytoreductive Radical Prostatectomy for Oligometastatic Prostate Cancer on Prostate-specific Membrane Antigen Positron Emission Tomography: Results of a Multicenter European Study.

BACKGROUND: De novo oligometastatic prostate cancer (omPCa) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) is a new disease entity and its optimal management remains unknown. OBJECTIVE: To analyze the outcomes of patients treated with cytoreductive radical prostatectomy (cRP) for omPCa on PSMA-PET. DESIGN, SETTING, AND PARTICIPANTS: Overall, 116 patients treated with cRP at 13 European centers were identified. Oligometastatic PCa was defined as miM1a and/or miM1b with five or fewer osseous metastases and/or miM1c with three or fewer lung lesions on PSMA-PET. INTERVENTION: Cytoreductive radical prostatectomy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Thirty-day complications according to Clavien-Dindo, continence rates, time to castration-resistant PCa (CRPC), and overall survival (OS) were analyzed. RESULTS AND LIMITATIONS: Overall, 95 (82%) patients had miM1b, 18 (16%) miM1a, and three (2.6%) miM1c omPCa. The median prebiopsy prostate-specific antigen was 14 ng/ml, and 102 (88%) men had biopsy grade group ≥3 PCa. The median number of metastases on PSMA-PET was 2; 38 (33%), 29 (25%), and 49 (42%) patients had one, two, and three or more distant positive lesions. A total of 70 (60%) men received neoadjuvant systemic therapy, and 37 (32%) underwent metastasis-directed therapy. Any and Clavien-Dindo grade ≥3 complications occurred in 36 (31%) and six (5%) patients, respectively. At a median follow-up of 27 mo, 19 (16%) patients developed CRPC and eight (7%) patients died. The 1-yr urinary continence rate was 82%. The 2-yr CRPC-free survival and OS were 85.8% (95% confidence interval [CI] 78.5-93.7%) and 98.9% (95% CI 96.8-100%), respectively. The limitations include retrospective design and short-term follow-up. CONCLUSIONS: Cytoreductive radical prostatectomy is a safe and feasible treatment option in patients with de novo omPCa on PSMA-PET. Despite overall favorable oncologic outcomes, some of these patients have a non-negligible risk of early progression and thus should be considered for multimodal therapy. PATIENT SUMMARY: We found that patients treated at expert centers with surgery for prostate cancer, with a limited number of metastases detected using novel molecular imaging, have favorable short-term survival, functional results, and acceptable rates of complications.

Perioperative and Functional Results for Robot-assisted Radical Cystectomy with Totally Intracorporeal Neobladder in Male Patients via the Vesica Patavina (Ves.Pa.) Technique: IDEAL Stage 2a Report.

Background: Robot-assisted radical cystectomy (RARC) offers several advantages over open surgery, but intracorporeal neobladder construction (INC) is a challenging procedure. The vesica patavina (Ves.Pa.) refinement is a modification of the original technique that simplifies the neobladder configuration and reduces the risk of complications. Objective: To present a stage 2a IDEAL (Idea, Development, Exploration, Assessment and Long-term follow-up) report on RARC with INC using the Ves.Pa. technique. Design setting and participants: This was a prospective study of consecutive male patients undergoing RARC and Ves.Pa. INC performed by a single surgeon for muscle-invasive or non-muscle-invasive, bacillus Calmette-Guérin-refractory urothelial bladder cancer in a tertiary referral center. Surgical procedure: RARC with INC using the refined Ves.Pa. technique. Measurements: Complications were classified using the Clavien-Dindo scheme, and functional outcomes were assessed using validated questionnaires. Results and limitations: A total of 20 male patients were treated. The median operative time was 382 min, and the median estimated blood loss was 350 ml. The incidence of high-grade complications was extremely low, with only one patient experiencing a grade IIIa complication. All patients had clear surgical margins. At median follow-up of 12 mo, statistically significant differences in all the functional scores measured were observed. Specifically, 6-mo parameters were all significantly worse than at baseline (all p < 0.05). No patients required intermittent catheterization. Severe urinary incontinence was experienced by approximately 25% of the patients. The median number of pad used was 0 during the day and 1 at night. The study is limited by its small sample size, single-center design, and short follow-up. Conclusions: RARC with the refined Ves.Pa. technique for INC is safe, feasible, and replicable. The technique simplifies the procedure and reduces the risk of complications. The study results suggest acceptable oncological and functional outcomes over short-term follow-up. Patient summary: We report our initial experience with robot-assisted removal of the bladder and construction of a new bladder using our modified technique, called Ves.Pa., in patients with bladder cancer. The technique is simple to perform. We observed a low rate of high-grade complications, and patients had surgical margins negative for cancer in all cases and fair functional outcomes at 12-month follow-up.

The impact of a second MRI and re-biopsy in patients with initial negative mpMRI-targeted and systematic biopsy for PIRADS ≥ 3 lesions.

OBJECTIVE: To evaluate the proportions of detected prostate cancer (PCa) and clinically significant PCa (csPCa), as well as identify clinical predictors of PCa, in patients with PI-RADS > = 3 lesion at mpMRI and initial negative targeted and systematic biopsy (initial biopsy) who underwent a second MRI and a re-biopsy. METHODS: A total of 290 patients from 10 tertiary referral centers were included. The primary outcome measures were the presence of PCa and csPCa at re-biopsy. Logistic regression analyses were performed to evaluate predictors of PCa and csPCa, adjusting for relevant covariates. RESULTS: Forty-two percentage of patients exhibited the presence of a new lesion. Furthermore, at the second MRI, patients showed stable, upgrading, and downgrading PI-RADS lesions in 42%, 39%, and 19%, respectively. The interval from the initial to repeated mpMRI and from the initial to repeated biopsy was 16 mo (IQR 12-20) and 18 mo (IQR 12-21), respectively. One hundred and eight patients (37.2%) were diagnosed with PCa and 74 (25.5%) with csPCa at re-biopsy. The presence of ASAP on the initial biopsy strongly predicted the presence of PCa and csPCa at re-biopsy. Furthermore, PI-RADS scores at the first and second MRI and a higher number of systematic biopsy cores at first and second biopsy were independent predictors of the presence of PCa and csPCa. Selection bias cannot be ruled out. CONCLUSIONS: Persistent PI-RADS ≥ 3 at the second MRI is suggestive of the presence of a not negligible proportion of csPca. These findings contribute to the refinement of risk stratification for men with initial negative MRI-TBx.

Urology: a trip into metaverse.

PURPOSE: Metaverse is becoming an alternative world in which technology and virtual experiences are mixed with real life, and it holds the promise of changing our way of living. Healthcare is already changing thanks to Metaverse and its numerous applications. In particular, Urology and urologic patients can benefit in many ways from Metaverse. METHODS: A non-systematic literature review identified recently published studies dealing with Metaverse. The database used for this review was PubMed, and the identified studies served as the base for a narrative analysis of the literature that explored the use of Metaverse in Urology. RESULTS: Virtual consultations can enhance access to care and reduce distance and costs, and pain management and rehabilitation can find an incredible support in virtual reality, reducing anxiety and stress and improving adherence to therapy. Metaverse has the biggest potential in urologic surgery, where it can revolutionize both surgery planning, with 3D modeling and virtual surgeries, and intraoperatively, with augmented reality and artificial intelligence. Med Schools can implement Metaverse in anatomy and surgery lectures, providing an immersive environment for learning, and residents can use this platform for learning in a safe space at their own pace. However, there are also potential challenges and ethical concerns associated with the use of the metaverse in healthcare. CONCLUSIONS: This paper provides an overview of the concept of the metaverse, its potential applications, challenges, and opportunities, and discusses the implications of its development in Urology.

Chronic Prostatitis/Chronic Pain Pelvic Syndrome and Male Infertility.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is defined as urologic pain or discomfort in the pelvic region, associated with urinary symptoms and/or sexual dysfunction, lasting for at least 3 of the previous 6 months. The rate of symptoms related to prostatitis has a mean prevalence of 8-8.2%. CP/CPPS is most frequent in men younger than 50 years, among whom it is the most common urologic diagnosis. In the last decades, many studies have been published on CP/CPPS and its association with male infertility. The pathophysiologic relation between CP/CPPS and male infertility involves several aspects, which are not well studied yet. A reduction in semen parameters has been demonstrated in patients with CP/CPPS, and several mechanisms have been proposed to represent putative pathophysiological links between CP/CPPS and infertility, including male accessory gland inflammation, metabolic syndrome, inflammatory bowel disease, HPV co-infection and autoimmunity. In light of this evidence, a multidisciplinary approach is advocated for patients with known CP/CPPS, and particular attention is needed for male patients of infertile couples in order to evaluate male accessory glands correctly. In addition, it is advisable that future studies dealing with the treatment of CP/CPPS take into consideration all the different pathophysiological aspects implicated.
