Video-Assisted Informed Consent in Endoscopic Urology: A Randomized Trial on Ureteroscopy.

Purpose: The aim of this study is to evaluate the possible benefits of using video consent in the preoperative ureteroscopy (URS) consent process. Material and Methods: Prospective randomized trials took place at two Italian tertiary-care centers from March 2022 to September 2022. Patients were randomly assigned to two groups: Group A (standard verbal/written informed consent) and Group B (informed consent supported by video). We investigated the impact of both types of informed consent on patient anxiety levels using the Spielberger State-Trait Anxiety Inventory (STAI) questionnaire both pre- and post-consent. In addition, using the Visual Analogue Scale, analysis of the effect of informed consent on postoperative pain and the number of calls for assistance during hospitalization as secondary outcomes was done. To assess the satisfaction level related to the whole process, patients were asked to rate their experience on a scale of 1-10, with 1 indicating "not satisfied" and 10 indicating "completely satisfied." Results: Overall, 166 patients were randomized 1:1 in each group. The multivariable regression model demonstrated that video-assisted informed consent significantly increased the difference between post- and pre-consent STAI with a reduced level of anxiety. The video-assisted informed consent significantly predicted the number of assistance calls during hospitalization. Conclusions: Video consent for ureteroscopies is a valid tool to improve procedure awareness and satisfaction. Video consent is able to reduce procedure-related patient anxiety and postoperative assistance calls, thus proving to be useful in obtaining better-informed consent for endourological procedures.

The Lifetime History of the First Italian Public Extra-Corporeal Shock Wave Lithotripsy (ESWL) Lithotripter as a Mirror of the Evolution of Endourology over the Last Decade.

Extracorporeal shockwave lithotripsy (ESWL) is the only non-invasive treatment for kidney stones. It does not require an operating room, anesthesia, or hospital stay. Its role evolved over the years and nowadays ESWL is slowly disappearing from many stone centers and urologic departments. We present the history and the role of ESWL treatment since its birth in 1959 and its development through the following years. We also present details of its application and impact on the first Italian stone center in 1985. ESWL has had different roles over the centuries: in the early years it was a great alternative to open surgery and percutaneous nephrolithotripsy (PCNL), then it had its decline with the introduction of the miniscopes. Currently, although ESWL is not considered a treatment of excellence, newer models are emerging. With the application of new technologies and artificial intelligence, this technique can become a good option alongside endourologic treatments.

Oligometastatic Prostate Cancer Treated with Metastasis-Directed Therapy Guided by Positron Emission Tomography: Does the Tracer Matter?

The superior diagnostic accuracy of [68Ga]Ga-prostate-specific membrane antigen-11 (PSMA) ([68Ga]Ga-PSMA-11) compared to [18F]F-Fluorocholine Positron Emission Tomography/Computed Tomography (PET/CT) in Prostate Cancer (PCa) is established. However, it is currently unclear if the added diagnostic accuracy actually translates into improved clinical outcomes in oligometastatic PCa patients treated with [68Ga]Ga-PSMA-11 PET-guided metastasis-directed therapy (MDT). The present study aimed to assess the impact of these two imaging techniques on Progression-Free Survival (PFS) in a real-world sample of oligometastatic PCa patients submitted to PET-guided MDT. Thirty-seven oligometastatic PCa patients treated with PET-guided MDT were retrospectively enrolled. MDT was guided by [18F]F-Fluorocholine PET/CT in eleven patients and by [68Ga]Ga-PSMA-11 PET/CT in twenty-six. Progression was defined as biochemical recurrence (BR), radiological progression at subsequent PET/CT imaging, clinical progression, androgen deprivation therapy initiation, or death. Clinical and imaging parameters were assessed as predictors of PFS. [18F]F-Fluorocholine PET-guided MDT was associated with significantly lower PFS compared to the [68Ga]Ga-PSMA-11 group (median PFS, mPFS 15.47 months, 95% CI: 4.13−38.00 vs. 40.93 months, 95% CI: 40.93−40.93, respectively; p < 0.05). Coherently, the radiotracer used for PET-guided MDT resulted in predictive PFS at the univariate analysis, as well as the castration-resistant status at the time of MDT and the PSA nadir after MDT. However, in the multivariate analysis, castration resistance and PSA nadir after MDT remained the sole independent predictors of PFS. In conclusion, in the present proof-of-concept study, [68Ga]Ga-PSMA-11 provided higher PFS rates than [18F]F-Fluorocholine imaging in oligometastatic PCa patients receiving PET-guided MDT. Although preliminary, this finding suggests that enlarging the "tip of the iceberg", by detecting a major proportion of the submerged disease thanks to next-generation imaging may favourably impact the oncological outcome of oligometastatic PCa treated with MDT.

From women to women-hematuria during therapy for metastatic breast cancer, what to suspect and when to be alarmed; Bladder metastasis from breast cancer-our experience and a systematic literature review.

Breast cancer is one of the most important causes of premature mortality in women worldwide. Around 12% of breast cancer patients will develop metastatic disease, a stage associated with poor prognosis, and only 26% of patients are likely to survive for at least 5 years after being diagnosed. Although the most common sites where breast cancer tends to spread are bones, lungs, brain, and liver, it is important that physicians consider other less frequent organs and viscera, like the bladder, as a target destination. In this article we report our experience with this rare form of metastases and a systematic literature review. We analyzed case reports, case series, and review articles present in PubMED/MEDLINE up to March 2022. We excluded the nonrelevant articles, editorials, letters to the editor, and articles written in other languages. We identified a total of 302 articles, with 200 articles being removed before screening; therefore, the total number of abstracts reviewed was 102. Fifty-five articles were excluded before full text review because they did not meet the inclusion criteria, and one article was not retrievable. Therefore, we included a total of 45 articles in this review. The intention of this review is to highlight the importance of the early detection of bladder metastases and to facilitate the diagnostic process for the responsible physician. The most common signs and symptoms and breast cancer subtype associated with bladder metastases, as well as overall survival after their detection, were all assessed. Bladder metastases from metastatic breast cancer are prevalent in the invasive, lobular breast cancer subtype; most patients present with hematuria (39.5%) and the relative 5-year survival rate is 2%. The main limitations of this review are the low number of cases reported in the literature, clinical and pathological differences between the individual cases, and absence of the control group. This study was not funded.

Atlas of Ex Vivo Prostate Tissue and Cancer Images Using Confocal Laser Endomicroscopy: A Project for Intraoperative Positive Surgical Margin Detection During Radical Prostatectomy.

BACKGROUND: Confocal laser endomicroscopy (CLE) is an optical device that aims to image histological architecture and may be used to reduce positive surgical margins. The ability of CLE to describe prostatic and periprostatic tissues, and prostate cancer (PCa) is still an object of investigation. OBJECTIVE: To create an atlas of ex vivo CLE images of prostatic and periprostatic tissues, and PCa in order to recognise different prostatic structures. DESIGN, SETTING, AND PARTICIPANTS: From November 2017 to February 2018, 15 patients underwent radical prostatectomy for biopsy-proven PCa. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Based on preoperative data and macroscopic examination, tumour location was assessed and confirmed on frozen sections. Prior to ex vivo CLE analysis, prostates were stained with fluorescein 10%. We used a GastroFlex probe to collect images of periprostatic tissue (adipose tissue, fibrous and connective tissues, vessels, nerve sheets, seminal vesicles, and urethra). Normal prostatic glands and tumour tissue according to the Gleason grade were analysed. Each PCa Gleason score was represented. RESULTS AND LIMITATIONS: A total of 139 video clips and 237 pictures of prostatic and periprostatic tissues were collected. Among them, we selected 16 highly representative images. Adipose tissue, fibrous tissue, and connective tissue were supposable in all 15 specimens. PCa glands captured fluorescein in their cytoplasm, normal prostatic glands did not capture fluorescein, and glandular structures were easily recognisable. The principal limitation of this study is its ex vivo nature of the study. CONCLUSIONS: Each CLE image was correlated with the corresponding haematoxylin/eosin/saffron definitive pathology image, allowing building of an atlas as a necessary tool to assess the diagnostic performance of CLE during radical prostatectomy in achieving negative surgical margins. PATIENT SUMMARY: In this study, we aim to provide an atlas of images illustrating prostatic, periprostatic, and PCa tissues obtained using Cellvizio confocal laser endomicroscopy as a tool for further interpretation of intraoperative surgical margins during radical prostatectomy.

Pain and discomfort after Retzius-sparing robot-assisted radical prostatectomy: a comparative study between suprapubic cystostomy and urethral catheter as urinary drainage.

BACKGROUND: The aim of this study is to evaluate differences in discomfort, complications and functional results after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) according to different urinary drainage: suprapubic tube (SPT) and standard urethral catheter (UC). METHODS: Prospective, comparative, consecutive, non-randomized study. In all patients with a water-tight anastomosis, no hematuria, obesity, previous suprapubic surgery or history of bladder cancer, a SPT (two-way Foley 14-Fr catheter) was positioned instead of a Foley 18-Fr UC. One week after surgery, an institutional self-compiled questionnaire was administered. The patients were divided into two groups according to the presence of UC or SPT and were compared concerning pain, perioperative results, complications, functional outcomes. RESULTS: Fifty-six patients with UC and 135 with SPT agreed to participate to the study. Median postoperative pain score was 3 (IQR: 2-5) in UC and 3 (IQR: 1-5) in SPT group (P=0.324); urinary drain-related pain scores were 3 (IQR: 1-5) in UC and 1 (IQR: 0-3) in SPT groups (P<0.001); catheter removal related scores were 1 (IQR: 0-3) and 1 (IQR: 1-3) (P=0.317), respectively. Lastly, 17.8% (UC) and 31.1% (SPT) wore a protection (small or medium pad) while the urinary drainage was in place (P=0.061). No differences related to complications were found (P=0.085); 7.9% of patients in UC group and 4.2% in SPT group (P=0.178) used pads one year after surgery. CONCLUSIONS: We demonstrated suprapubic tube to be more comfortable than transurethral catheter after RARP, with a possible advantage concerning anastomotic postoperative problems.

Outcomes after salvage radical prostatectomy and first-line radiation therapy or HIFU for recurrent localized prostate cancer: results from a multicenter study.

INTRODUCTION: Despite no consensus on the optimal management of recurrent prostate cancer after primary radiation or HIFU therapy, salvage prostatectomy (sRP) is reserved for only 3% of patients because of technical challenges and frequent post-operative complications. We assessed outcomes after sRP in a series of patients with localized PCa and that had received radiation therapy or HIFU as a first-line treatment. MATERIALS AND METHODS: Data from nine French referral centers on patients treated with sRP between 2005 and 2017 were collected. Pre- and post-operative data, including oncological and functional outcomes after first treatment and sRP, were analyzed to determine the predictors for biochemical recurrence (BCR) and cancer-specific survival (CSS) after sRP. RESULTS: First-line treatments were external beam-radiation therapy (EBRT) for 30 (55%), brachytherapy (BT) for 10 (18%), and high-intensity focused ultrasound (HIFU) for 15 (27%). Median (IQR) PSA at diagnosis was 6.4 (4.9-9.5) ng/mL, median PSA at nadir was 1.9 (0.7-3.0) ng/mL, and median (IQR) to first BCR was 13 (6-20) months. Of the 55 patients, 44 (80%) received robot-assisted salvage radical prostatectomy and 11 (20%) received salvage retropubic radical prostatectomy. Restoration of continence was achieved in 90% of preoperatively continent patients; 24% that had received nerve-sparing (NS) procedures were potent after surgery. Prolonged catheterization due to anastomotic leakage was the most common complication. Age, preoperative clinical stage, NS procedure, and a pathological Gleason score were predictors for BCR. CONCLUSIONS: sRP was safe, feasible, and effective using either an open or robot-assisted approach, in experienced hands. Age, preoperative clinical stage, NS procedure, and pathological GS were linked with BCR after sRP.

Does prostate volume have an impact on the functional and oncological results of Retzius-sparing robot-assisted radical prostatectomy?

BACKGROUND: The objective of our study is to evaluate the effect of prostatic volume on the outcomes of Retzius-sparing robot-assisted radical prostatectomy (RSP). METHODS: All the consecutive patients undergoing RSP up to January 2015 were included. The series was divided into three groups based on prostate weight at radical prostatectomy specimen (<40 g, 40-60 g, >60 g). Perioperative, oncological and functional data were prospectively recorded. Potency was defined as erections sufficient for penetration; continence as no pad or one safety liner. Oncological results were reported as positive surgical margins (PSMs) and 1-year biochemical disease-free survival (PSA<0.2 ng/mL). RESULTS: We evaluated 750 patients (366 with <40 g prostates, 272 with 40-60 g prostates, 112 with >60 g prostates). Median follow-up was 22 months; PSA was higher in larger prostates (6.6 vs. 6.8 vs. 8 ng/mL). Nerve-sparing and bladder-neck sparing procedures were in similar percentages. Larger prostates required longer surgeries (90 vs. 100 vs. 100 minutes, P=0.002). Perioperative results were similar (blood loss, discharge, complications, catheter removal). Larger prostates had more frequently localized disease (pT2 in 49.5% vs. 60.7% vs. 68.5%; P=0.001); PSMs were similar both in pT2 (15.5% vs. 9.4% vs. 11.8%) and in pT3 cases (40.1% vs. 42% vs. 34%). In the three study groups, immediate continence was reached by 88%, 89.5% and 81.3% (P=0.045), while no differences were observed concerning continence (93.4%, 94.1%, 94.7%; P=0.892) or potency after follow-up. CONCLUSIONS: RSP is feasible in patients with prostates of any volume, with similar oncological and functional outcomes. Despite being inferior to the figures obtained in low volume prostates, the very high immediate continence rates observed in larger prostates encourage the use of this approach also in larger prostates.

Predicting survival in node-positive prostate cancer after open, laparoscopic or robotic radical prostatectomy: A competing risk analysis of a multi-institutional database.

OBJECTIVES: To investigate cancer-specific mortality and other-cause mortality in prostate cancer patients with nodal metastases. METHODS: The study included 411 patients treated with radical prostatectomy and pelvic lymph node dissection for prostate cancer with lymph node metastases at 10 tertiary care centers between 1995 and 2014. Kaplan-Meier analyses were used to assess cancer-specific mortality-free survival rates at 8 years' follow up in the overall population, and after stratifying patients according to clinical and pathological parameters. Uni- and multivariable competing risk Cox regression analyses were used to assess cancer-specific mortality and other-cause mortality. Finally, cumulative-incidence plots were generated for cancer-specific mortality and other-cause mortality after stratifying patients according to the number of positive lymph nodes and the median age at surgery, according to the competing risks method. RESULTS: Men with prostate-specific antigen ≤40 ng/mL and those with one to three positive lymph nodes showed higher cancer-specific mortality-free survival estimates as compared with their counterparts with prostate-specific antigen >40 ng/mL and >3 metastatic lymph nodes, respectively (all P < 0.001). At multivariable Cox regression analyses, preoperative prostate-specific antigen >40 ng/mL, >3 lymph node metastases and pathological Gleason score 8-10 were all independent predictors of cancer-specific mortality (all P-values ≤0.001). On competing risk analysis, when patients were stratified according to the number of positive lymph nodes (namely, ≤3 vs >3), the 8-year cancer-specific mortality rates were 27.4% versus 44.8% for patients aged <65 years, and 15.2% versus 52.6% for patients aged ≥65 years, respectively. CONCLUSIONS: Three positive lymph nodes represent the best prognostic cut-off in node-positive prostate cancer patients. In those individuals with >3 positive lymph nodes, the overall mortality rate is completely related to prostate cancer in young patients.
