Bladder Outlet Obstruction Relief and Symptom Improvement Following Medical and Surgical Therapies for Lower Urinary Tract Symptoms Suggestive of Benign Prostatic Hyperplasia: A Systematic Review.

BACKGROUND AND OBJECTIVE: Symptomatic benefit and urodynamic obstruction relief represent relevant outcomes of therapies for lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). We summarized evidence from studies concurrently assessing variations in terms of symptoms severity and invasive urodynamic measures of obstruction following medical and surgical therapies for LUTS/BPH. METHODS: We performed a systematic review of PubMed, Scopus, and Web of Science in June 2023. KEY FINDINGS AND LIMITATIONS: We identified 29 publications: 14 (872 patients) and 15 (851 patients) studies addressing medical and surgical therapies, respectively. The mean percentage total International Prostate Symptom Score (IPSS) improvements ranged from -2.5% to 56.3% and from 35.1% to 82.1% following medical and surgical therapies, respectively. The corresponding mean percentage Bladder Outlet Obstruction Index (BOOI) improvements ranged from 7.8% to 53.5% and from 22.4% to 138.6%, respectively. Holmium laser enucleation of the prostate (HoLEP) provided IPSS improvements in the higher range and the greatest BOOI reduction. CONCLUSIONS AND CLINICAL IMPLICATIONS: Globally, based on available evidence, more pronounced symptomatic benefits are observed following treatments providing greater deobstructive effect. In detail, patients undergoing surgery exhibit greater IPSS and BOOI improvements than those receiving medical therapy. PATIENT SUMMARY: Treatments for lower urinary tract symptoms suggestive of benign prostatic hyperplasia providing greater urodynamic improvements also provide greater symptomatic benefit. Surgical procedures provide greater symptomatic and urodynamic outcomes than medical therapies. Maximal obstruction relief, together with symptomatic benefits in the higher ranges, is observed following holmium laser enucleation of the prostate.

Antibiotic prophylaxis in invasive urodynamics, a Delphi consensus of the Italian Society of Urodynamics (SIUD).

INTRODUCTION: Although antibiotic prophylaxis (AB) demonstrated a statistically significant reduction in bacteriuria after invasive urodynamics (UDS), no significant decrease in the incidence of urinary tract infections (UTI) has been confirmed. No absolute recommendations on the use of AB in case of relevant potential risk of UTI have been reported, though some categories of patients at increased infective probability after UDS have been recognized. The aim of this study is to report the experts' consensus on the best practice for the use of AB before UDS in the main categories of patients at potential risk of developing UTI. MATERIALS AND METHODS: A systematic literature review was performed on AB before UDS in males and females. A panel of experts from the Italian Society of Urodynamics, Continence, Neuro-Urology, and Pelvic Floor (SIUD) assessed the review data and decided by a modified Delphi method on 16 statements proposed and discussed by the panel. The cut-off percentage for the consensus was a ≥70% of positive responses to the survey. The study was a Delphi consensus with experts' opinions, not a clinical trial involving directly patients. RESULTS: The panel group was composed of 57 experts in functional urology and UDS, mainly urologists, likewise gynaecologists, physiatrists, infectivologists, pediatric urologists, and nurses. A positive consensus was achieved on 9/16 (56.25%) of the statements, especially on the need for performing AB before UD in patients with neurogenic bladder and immunosuppression. Urine analysis and urine culture before UDS are mandatory, and in the event of their positivity, UDS should be postponed. A consensus was reached on avoiding AB in menopausal status, diabetes, age, gender, bladder outlet obstruction, high postvoid residual, chronic catheterization, previous urological surgery, lack of urological abnormalities, pelvic organ prolapse, and negative urine analysis. CONCLUSIONS: Antibiotic prophylaxis is not recommended for patients without notable risk factors and with a negative urine test due to the potential morbidities that may result from antibiotic administration. However, AB can be used for risk categories such as neurogenic bladder and immunosuppression. The evaluation of urine analysis and urine culture and postponing UDS in cases of positive tests were considered good practices, as well as performing AB in the neurogenic bladder and immunosuppression.

Advances in Urinary Diversion: From Cutaneous Ureterostomy to Orthotopic Neobladder Reconstruction-A Comprehensive Review.

Bladder cancer ranks as the 10th most prevalent cancer globally with an increasing incidence. Radical cystectomy combined with urinary diversion represents the standard treatment for muscle-invasive bladder cancer, offering a range of techniques tailored to patient factors. Overall, urinary diversions are divided into non-continent and continent. Among the first category, cutaneous ureterostomy and ileal conduit represent the most common procedures while in the second category, it could be possible to describe another subclassification which includes ureterosigmoidostomy, continent diversions requiring catheterization and orthotopic voiding pouches and neobladders. In this comprehensive review, urinary diversions are described in their technical aspects, providing a summary of almost all alternatives to urinary diversion post-radical cystectomy.

Role of spinal anesthesia in robot-assisted radical prostatectomy: Gamble or opportunity?

To the Editor, Although postoperative pain associated with robot-assisted radical prostatectomy (RARP) is less than pain following the open technique, it remains a fundamental issue as it can be a significant source of discomfort for the patient and lengthen recovery times after surgery. The optimal management of pain after RARP is far from being fully elucidated and many factors have to be evaluated to choose the best analgesic approach. [...].

Functional and oncological outcomes after radical prostatectomy in patients with history of surgery for lower urinary tract symptoms related to benign prostatic enlargement: A systematic review with meta-analysis.

BACKGROUND: Outcomes of radical prostatectomy (RP) in men with history of lower urinary tract symptoms related to benign prostatic enlargement (LUTS/BPE) surgery represents a controversial issue. We performed an updated systematic review and meta- analysis evaluating oncological and functional outcomes of RP in this subset of patients. METHODS: Eligible studies were identified from MEDLINE, Web of Science and the Scopus databases. The following outcomes were evaluated: incidence of positive surgical margins (PSM), incidence of biochemical recurrence (BCR), 3-mo and 1-year urinary continence (UC) rates, incidence of nerve-sparing (NS) procedures, 1-year erectile function (EF) recovery rates. We estimated pooled Odds ratios (OR) and 95% confidence intervals (CI) using random effects models. Sub-analyses were performed according to the type of RP and LUTS/BPE surgery. RESULTS: Twenty-five retrospective studies including 11,101 patients undergoing RP were included in the analysis (2113 with history of LUTS/BPE surgery, and 8898 controls). PSM rate was significantly higher in patients with history of LUTS/BPE surgery (OR 1.39, 95% CI 1.18-1.63, p < 0.001). No statistically significant difference in terms of BCR emerged between patients with or without history of LUTS/BPE surgery (OR 1.46, 95% CI 0.97-2.18, p = 0.066). Three-months and 1-year UC rates were significantly lower in patients with previous LUTS/BPE surgery (OR 0.48, 95% CI 0.34-0.68, p < 0.001 and OR 0.44, 95% CI 0.31-0.62, p < 0.001; respectively). Although not statistically significant differences between the two groups emerged in terms of adoption of NS procedures (OR 0.59, 95% CI 0.32-1.12, p = 0.107), 1-year EF recovery was significantly lower in patients with history of LUTS/BPE procedures (OR 0.60, 95% CI 0.40-0.89, p = 0.010). CONCLUSIONS: In conclusions, RP in patients with history of previous LUTS/BPE surgery is associated with increased incidence of PSM, lower UC rates at both 3-months and 1-year follow-up as well as lower rates of EF recovery at 1-year follow-up.

Voice Assistants as Consultants for Male Patients with Sexual Dysfunction: A Reliable Option?

The aim of this study was to evaluate the ability of Google Assistant, Alexa, and Siri to recognize and answer questions about male sexual health. Each VA was tested on a smart speaker: Alexa on Amazon Echo Dot 4th Gen., Google Assistant on Google Home Mini, and Siri on Apple HomePod. A pool of patients' frequently asked questions regarding erectile dysfunction (ED), premature ejaculation (PE), Peyronie's disease (PD), male infertility, and other aspects of male sexual health were identified by authors. The recognition of question was evaluated ("yes" or "not"). For each recognized question, the response characteristics (domains) were rated on a scale from 0 to 10 (according to the quality). We chose the recognition rate of the questions as the primary outcome and the quality of the answers as the secondary outcome. Overall, the best VA in recognizing questions was Siri, with a total of 83.3% questions compared with 64.0% for Alexa (p = 0.024) and 74.0% for Google Assistant (p = 0.061). Siri was associated with a significantly higher recognition rate than Alexa for PE (80% vs. 40%; p = 0.002) and PD (66.7% vs. 33.3%; p = 0.010). The quality of the responses was classified as low in 57 out of 105 cases (54.3%), intermediate in 46 cases (43.8%), and high in only 2 cases (1.9%), highlighting an overall intermediate-low quality of the answers. Male infertility was the condition associated with the highest mean scores in "Targeted response to the problem" (7.32 ± 2.57), "Scientific correctness of the answer", (5.9 ± 2.76) "Completeness of the answer" (5.14 ± 2.56), and "Understandability of the response for a patient" (5.3 ± 2.51) domains. Siri was associated with significantly higher scores than Alexa (p < 0.05) in several domains of all conditions evaluated. The question recognition rate of VAs is quite high; however, the quality of the answers is still intermediate-low. Siri seems superior to Alexa in both question recognition and response quality. Male infertility appears to be the sexual dysfunction best addressed by VAs.

Hand-Sewn Versus Stapled Small Bowel Anastomoses in Patients With Secondary Mesenteric Ischemia.

INTRODUCTION: Although stapled anastomoses have been widely evaluated in the context of the elective surgery, few reports compared manual with stapled anastomoses in patients undergoing emergency surgery. The aim of this study is to compare the outcome of hand-sewn end-to-end anastomoses with stapled side-to-side and stapled end-to-side anastomoses in patients undergoing small bowel resection for acute mesenteric ischemia secondary to intestinal obstruction. METHODS: From January 2015 to June 2021 all the hemodynamically stable patients undergoing emergency surgery with small bowel resection for intestinal obstruction were enrolled in this study. According to surgical technique in performing anastomosis, the patients were divided into three groups: group 1: hand-sewn end-to-end anastomosis, group 2: stapled end-to-side anastomosis, and group 3: stapled side-to-side anastomosis. RESULTS: Although the anastomosis failure rate was higher in group 3, it was not significantly different between the three groups (P = 0.78: chi-square test). Likewise, no significant differences in the median hospital stay were found between the patients' groups (P = 0.87: Kruskal-Wallis test). The median operating time was similar in patients undergoing stapled anastomoses and was significantly higher in patients undergoing hand-sewn anastomoses (P = 0.0009: Kruskal-Wallis test). CONCLUSIONS: In patients undergoing emergency small bowel resection for complicated intestinal obstruction, a similar outcome in terms of dehiscence rate and hospital stay can be achieved performing stapled or hand-sewn anastomoses, even if restoring the intestinal continuity with stapled technique is associated with lower operating time.

Could YouTubeTM encourage men on prostate checks? A contemporary analysis.

OBJECTIVES: To assess YouTube™ videos' quality on prostate checks, especially on the digital rectal exam (DRE), and to investigate if they can inform patients correctly and eradicate their beliefs and myths. METHODS: A search using as keywords "digital rectal exam for prostate cancer" was performed on the YouTubeTM platform. We selected the first 100 videos. To assess video quality content, Patient Education Materials Assessment Tool for audio-visual content (PEMAT A/V) and Misinformation tool were used. RESULTS: Seventy-three videos were suitable for the analyses. The median PEMAT A/V Understandability score and PEMAT A/V Actionability score were 46.2% (interquartile range [IQR]: 30.8-76.9) and 50.0% (IQR: 25.0-75.0), respectively. The medi-an PEMAT A/V Understandability and Actionability scores were 69.2% (IQR: 46.2-88.5) vs 46.2% (IQR: 30.8-61.5) (p = 0.01) and 100.0% (IQR: 87.5-100.0) vs 25.0% (IQR: 25.0-68.8) (p < 0.001), for healthcare workers vs patients, respectively. According to the Misinformation tool, the median misinforma-tion score of the overall videos was 2.2 (IQR:1.7-2.8). According to the target audience, the misinformation score was 2.8 (IQR: 2.4-3.5) vs 2.0 (IQR: 1.5-2.8) (p = 0.02), for healthcare workers vs patients, respectively. CONCLUSIONS: Currently, based on our analyses, YouTubeTM videos' quality on DRE resulted unsatisfactory according to the PEMAT A/V score and the Misinformation tool. Videos targeted to healthcare workers got higher quality scores if compared to videos targeted to patients. Therefore, YouTubeTM videos' may not be considered a reliable source of information on DRE for patients.

ß3 Relaxant Effect in Human Bladder Involves Cystathionine γ-Lyase-Derived Urothelial Hydrogen Sulfide.

It is now well established that the urothelium does not act as a passive barrier but contributes to bladder homeostasis by releasing several signaling molecules in response to physiological and chemical stimuli. Here, we investigated the potential contribution of the hydrogen sulfide (H2S) pathway in regulating human urothelium function in ß3 adrenoceptor-mediated relaxation. The relaxant effect of BRL 37344 (0.1-300 µM), a selective ß3 adrenoceptor agonist, was evaluated in isolated human bladder strips in the presence or absence of the urothelium. The relaxant effect of BRL 37344 was significantly reduced by urothelium removal. The inhibition of cystathionine-γ-lyase (CSE), but not cystathionine-ß-synthase (CBS), significantly reduced the BRL 37344 relaxing effect to the same extent as that given by urothelium removal, suggesting a role for CSE-derived H2S. ß3 adrenoceptor stimulation in the human urothelium or in T24 urothelial cells markedly increased H2S and cAMP levels that were reverted by a blockade of CSE and ß3 adrenoceptor antagonism. These findings demonstrate a key role for urothelium CSE-derived H2S in the ß3 effect on the human bladder through the modulation of cAMP levels. Therefore, the study establishes the relevance of urothelial ß3 adrenoceptors in the regulation of bladder tone, supporting the use of ß3 agonists in patients affected by an overactive bladder.

Male Sexual Dysfunction and Infertility in Spinal Cord Injury Patients: State-of-the-Art and Future Perspectives.

Spinal cord injury (SCI) is a relevant medical and social problem. According to the World Health Organization, the commonly estimated worldwide annual incidence of SCI is 40 to 80 cases per million population. After the SCI experience, most men present with sexual dysfunction (erectile dysfunction (ED) and ejaculatory dysfunction), fertility problems (such as impaired spermatogenesis, abnormalities in sperm viability, motility, and morphology), and systemic disorders such as genitourinary infection and endocrine imbalances. The best options available for managing the ejaculatory disorders in patients suffering from SCI are penile vibratory stimulation (PVS) and electroejaculation (EEJ). Furthermore, the treatment of ED in SCI patients consists of medical therapies including phosphodiesterase 5 inhibitors (PDE5i), intracavernosal injections (ICI), vacuum erection devices (VEDs), and surgical as penile prosthesis (PP). This review provides a snapshot of the current evidence for the mechanisms of sexual dysfunction and infertility in SCI patients, discusses the best management strategies for these conditions, and offers our perspective on the direction of future research.

Prostate Cancer Diagnosis, Treatment and Outcomes in Patients with Previous or Synchronous Colorectal Cancer: A Systematic Review of Published Evidence.

The management of patients with prostate cancer (PCa) and previous or synchronous colorectal cancer (CRC) represents a challenging issue. A systematic review was performed in May 2022 to summarize available evidence about the diagnosis, management, and outcomes of these patients. Twenty-seven studies involving 252 patients were identified. Overall, 163 (64.7%) and 89 (35.3%) patients had synchronous and metachronous PCa and CRC, respectively. In patients with synchronous diseases, PCa treatment involved active surveillance in 1 patient, radical prostatectomy (RP) in 36 patients, radiotherapy (RT) in 60 patients, RP plus RT in 1 patient, proton beam therapy in 1 patient, and cryoablation in 1 patient. In patients with previous CRC treatment, prostate biopsy was mostly performed by transrectal approach (n = 24). The trans-perineal and suprapubic approaches were adopted in 12 and 6 cases, respectively. Surgical PCa treatment in these cases involved endoscopic extraperitoneal RP, robot-assisted RP, and not otherwise specified RP in 30, 15, and 2 cases, respectively. Biochemical recurrence rates ranged from 20% to 28%. Non-surgical PCa treatment options included brachytherapy, RT plus androgen deprivation therapy, and RT alone in 23, 2 and 4 patients, respectively. PCa specific survival was reported by one study and was 100%.

Hyperbaric oxygen therapy as adjuvant treatment for surgical site infections after male-to-female gender affirmation surgery: A 10-year experience.

INTRODUCTION: Several urological conditions that share an impairment of tissue oxygenation can benefit from hyperbaric oxygen therapy; limited evidence is available of its impact on patients undergoing male-to-female gender affirmation surgery. AIM: To evaluate the efficacy and safety of hyperbaric oxygen therapy as adjuvant treatment for surgical site infections in patients undergoing male-to-female gender affirmation surgery. METHODS: This research was conducted as an observational retrospective study. Patients undergoing male-to-female gender affirmation surgery at the principal investigators' institution from January 2009 to September 2019, with a discharge diagnosis of complicated superficial or deep wound infections, were included. All patients underwent standard management of wound infection. Subjects received/not-received hyperbaric oxygen therapy at the surgeon's discretion and were assigned to the hyperbaric oxygen therapy versus non-hyperbaric oxygen therapy group accordingly. Complete wound healing rate (primary outcome), duration of antibiotic therapy, perineal drain time, bladder catheter time, and hospital stay were recorded. All adverse events that occurred during the study period were described. RESULTS: A total of 156 patients underwent male-to-female gender affirmation surgery in the study period. Thirty-three patients were enrolled. Fifteen subjects belonged to the hyperbaric oxygen therapy group, the other 18 to the non-hyperbaric oxygen therapy group. No statistically significant differences were found between the two groups at baseline. Penile inversion vaginoplasty and intestinal vaginoplasty were performed in nine (60%) and six (40%) patients of the hyperbaric oxygen therapy group. Only penile inversion vaginoplasty was performed in subjects of the non-hyperbaric oxygen therapy group. Complete wound healing was obtained in 15 patients (100%) of the hyperbaric oxygen therapy group and 17 patients (94.4%) of the non-hyperbaric oxygen therapy group (p = 0.35). Duration of antibiotic therapy, perineal drain time, bladder catheter time, and hospital stay were significantly lower in the hyperbaric oxygen therapy group (p < 0.05). CONCLUSION: Our preliminary data suggest a role of hyperbaric oxygen therapy as adjuvant treatment for surgical site infection in patients undergoing male-to-female gender affirmation surgery. Randomized controlled trials properly powered are needed to confirm our findings.

COVID-19 Quarantine Dramatically Affected Male Sexual Behavior: Is There a Possibility to Go Back to Normality?

We performed a monocentric longitudinal study on sexually active male patients, from May 2021 to October 2021, with SARS-CoV-2 infection confirmed with a nasopharyngeal reverse transcriptase polymerase chain reaction (RT-PCR). The questionnaires were delivered by email. The study period was divided into the periods before getting tested (T1), during quarantine (T2), 1 month after a negative test (T3), and 3 months after a negative test (T4). All participants were invited to complete these questionnaires: 10- and 6-item questionnaires, a sexual distress schedule (SDS), and the international index of erectile function questionnaire of 15 items (IIEF-15). The primary endpoint was to evaluate the impact of quarantine on male sexual function (SF) during and after the SARS-CoV-2 infection. A total of 22 male patients met the inclusion criteria. The differences for both SDS and IIEF-15 scores, between T1−T2 (27 (IQR 24.0−32.2) vs. 37.5 (IQR 34.2−45.5), 45 (IQR 38.0−50.2) vs. 28.5 (IQR 19.5−38.0)), T2−T3 (37.5 (IQR 34.2−45.5) vs. 28 (IQR 24.0−31.0), and 28.5 (IQR 19.5−38.0) vs. 39.5 (IQR 35.5−44.2)) were statistically significant (p < 0.001), respectively. Moreover, between T1−T4, no statistically significant difference (p > 0.05) was recorded in both SDS (27 (IQR 24.0−32.2) vs. 26.5 (IQR 24−30.2)) and IIEF-15 (45 (IQR 38.0−50.2) vs. 28.5 (IQR 19.5−38.0)). In 20 patients (90.9%), SARS-CoV-2 had a huge impact on relationship and sexual life, but no patient attended a clinic for sexual difficulties. In conclusion quarantine has negatively influenced SF in infected patients; however, 3 months after the rRT-PCR negative test, a promising return to the preinfection SF values is observed.

Metastasis-Directed Radiation Therapy with Consolidative Intent for Oligometastatic Urothelial Carcinoma: A Systematic Review and Meta-Analysis.

The management of patients with oligometastatic urothelial carcinoma (UC) represents an evolving field in uro-oncology, and the role of metastasis-directed therapies, including metastasectomy and metastasis-directed radiation therapy (MDRT), is gaining increasing attention. Herein, we summarize available evidence about the role of MDRT with consolidative intent in oligometastatic UC patients. A systematic review was performed in December 2021. Six studies involving 158 patients were identified. Most patients (n = 120, 90.2%) had a history of bladder cancer and the most frequent sites of metastases were lymph nodes (n = 61, 52.1%) followed by the lungs (n = 34, 29%). Overall, 144 metastases were treated with MDRT. Median follow-up ranged from 17.2 to 25 months. Local control rates ranged from 57% to 100%. Median Overall Survival (OS) ranged from 14.9 to 51.0 months and median progression-free survival ranged from 2.9 to 10.1 months. Rates of OS at one and two years ranged from 78.9% to 96% and from 26% to 63%, respectively. Treatment-related toxicity was recorded in few patients and in most cases a low-grade toxicity was evident. MDRT with consolidative intent represents a potential treatment option for selected patients with oligometastatic UC.

Androgen deprivation therapy and cardiovascular risk in prostate cancer.

Androgen-deprivation therapy (ADT), with or without palliative local treatments, is the standard of care for many patients with locally-advanced and/or metastatic prostate cancer. However, the possible cardiovascular (CV) risks associated with gonadotropin-releasing hormone (GnRH) antagonists and agonists continue to be the subject of concern, especially in a patient population that may already be at increased CV risk. The present review provides a narrative summary of the evidence regarding the CV risks associated with GnRH antagonists and agonists from randomized clinical trials (RCTs), real-world evidence, and meta-analyses. From RCTs, it appears clear that there is a direct class effect for CV risk in patients with prostate cancer being administered GnRH agonists and antagonists, with the latter being associated with reduced CV risk. Real-world data and the available meta-analyses largely indicate that CV risk is lower with GnRH antagonists than with GnRH agonists. A review of the pathophysiological mechanisms of gives further support to the possibility that GnRH antagonists are associated with lower CV risk than agonists. It can be highlighted that when treating patients with advanced or metastatic prostate cancer it is important to screen for underlying comorbidities prior to choosing the most appropriate therapy; moreover, patients should be closely monitored for factors associated with CV risk in order to optimize outcomes. Further studies are needed to define the most appropriate treatment according to the individual patient characteristics.

Looking for cystoscopy on YouTube: Are videos a reliable information tool for internet users?

OBJECTIVE: The Internet is an important and easily accessible source of information. The aim of the current study was to investigate the quality of YouTube videos on cystoscopy and to establish if they can be used as a reliable information tool for internet users. MATERIALS AND METHODS: The search term "cystoscopy" was used on YouTube platform and the first 120 YouTube videos were analyzed. To assess the video quality Patient Education Materials Assessment Tool (PEMAT) for Audiovisual (A/V) Materials (Understandability and Actionability sections), Misinformation score and Global Quality Score (GQS) were used. RESULTS: Of all 120 videos, 72 were included in the analyses. Of all videos, 59.7% (n = 43), and 40.3% (n = 29) were targeted to General Public and Healthcare Workers. Moreover, "technical aspects" was the main topic addressed (n = 29, 40.3%). The median PEMAT A/V Understandability and Actionability scores were 50.0% (IQR: 39.1-70.0) and 66.7% (IQR: 33.3- 100.0), respectively. The median Misinformation score ranged from 1.0 to 3.0. According to GQS, 22 (30.6%), 26 (36.1%), 16 (22.2%), 8 (11.1%) videos were poor, generally poor, moderate, and good, respectively. No video was evaluated as excellent. CONCLUSIONS: Today, YouTube videos on cystoscopy are more frequently uploaded by healthcare workers, who share information about specific aspects of this procedure. However, the quality of YouTube contents on cystoscopy is still poor. Therefore, currently users interested in cystoscopy cannot rely on YouTube to get good informative material on this topic. In consequence, future authors should focus on improving the quality of video contents on cystoscopy.
