Prevalence and determinants of shared decision-making for PSA testing in the United States

BACKGROUND

Shared decision-making (SDM) is recommended for prostate-specific antigen (PSA) testing but appears underutilized. This population-based study assessed the prevalence and determinants of SDM for PSA testing among US men.

METHODS

We assessed PSA testing rates and SDM engagement in men aged 40 and older without prostate cancer history using the 2019 National Health Interview Survey. SDM was defined as discussing the advantages and disadvantages of PSA testing with a physician. We used multivariable logistic regression with machine learning to identify factors associated with lack of SDM.

RESULTS

Among 9723 eligible participants (mean age 58 years), lifetime PSA testing prevalence was 45.9% and the 1-year testing incidence was 29.1%. Only 24.1% reported engaging in SDM with a physician, while 62.9% never discussed PSA testing. Younger age and lower education levels were the primary determinants of decreased SDM engagement. Men with less education engaged in SDM less than half as often as those with higher education levels across all age groups.

CONCLUSIONS

Societal guidelines recommend SDM for PSA testing. However, most men, regardless of age, have never engaged in SDM conversations with a healthcare provider about PSA testing, especially those with less education. More efforts are needed to improve patient-provider conversations about the potential benefits and harms of PSA testing.

An analysis of benign prostatic hyperplasia surgical treatment reimbursement trends across Canada: Examining provincial changes over the recent decade with comparison to cost of living changes

INTRODUCTION

A variety of procedures for the endoscopic surgical treatment of symptomatic benign prostatic hyperplasia (BPH) refractory to medical therapy have existed for decades. The present study examines trends in surgeon compensation for these treatments within Canada.

METHODS

The physician fee schedule for BPH surgery across 10 Canadian provinces for the years 2010 and 2023 were obtained. A descriptive study examining first, the provincial reimbursement for transurethral resection of prostate (TURP) and laser ablative/enucleation surgery; second, the difference in TURP reimbursement between 2010 and 2023; and third, the annual change in TURP reimbursement juxtaposed with the annual change in the provincial Consumer Price Index (CPI) and annual salary for the working population aged 35-44.

RESULTS

Seven of 10 Canadian provinces reimburse laser BPH surgery equally to TURP. The average provincial TURP reimbursement is $545, ranging from $451 in Ontario to $688 in Saskatchewan. Since 2010, TURP reimbursement has varied by province from a 0% net change in Ontario to an increase of 21% in Nova Scotia. Reimbursement for TURP has increased at a slower pace than the local CPI, and for half of the provinces at a slower pace than the annual salary for people aged 35-44.

CONCLUSIONS

The compensation model for endoscopic BPH surgery does not have a unified structure in Canada that is consistent across provinces, nor does it keep up with inflation, possibly impacting future recruitment, increasing geographic disparities, and most importantly, limiting the adoption of new BPH therapies.

Ablative minimally invasive surgical therapies for benign prostatic hyperplasia: A review of Aquablation, Rezum, and transperineal laser prostate ablation

INTRODUCTION

Benign prostatic hyperplasia (BPH) is one of the most common diseases affecting men and can present with bothersome lower urinary tract symptoms (LUTS). Historically, transurethral resection of the prostate (TURP) has been considered the gold standard in the treatment of LUTS due to BPH. However, TURP and other traditional options for the surgical management of LUTS secondary to BPH are associated with high rates of sexual dysfunction. In the past decade, several novel technologies, including Aquablation therapy, convective water vapor therapy (Rezum), and transperineal prostate laser ablation (TPLA), have demonstrated promising evidence to be safe and effective while preserving sexual function.

METHODS

In this review, we discuss three ablative minimally invasive surgeries: Aquablation, Rezum, and TPLA. We review their techniques, safety, as well as perioperative and functional outcomes. We go into further detail regarding sexual function after these ablative minimally invasive surgical therapies.

RESULTS

Aquablation is a surgeon-guided, robot-executed, heat-free ablative waterjet procedure with sustained functional outcomes at 5 years while having no effect on sexual activity. Rezum is an innovative office-based, minimally invasive surgical option for BPH that delivers convective water vapor energy into prostate adenoma to ablate obstructing tissue. Rezum leads to significant improvements in Qmax, IPSS while preserving sexual function. TPLA is another office-based technology which uses a diode laser source to produce thermoablation. It leads to improvement in Qmax, IPSS, and QoL while preserving ejaculatory function.

CONCLUSIONS

Overall, ablative minimally invasive surgical therapies have demonstrated excellent safety and efficacy profiles while preserving sexual function. These modalities should be discussed with patients to ensure informed and shared decision-making. Ablative minimally invasive surgical therapies may be particularly interesting to patients who value the preservation of their sexual function.

Analyzing the influence of expanding multispecialty adoption of robotic surgery on robotic urologic care: A decade-long assessment of two Canadian academic hospitals

INTRODUCTION

Most robot-assisted surgery (RAS) systems in Canada are donor-funded, with constraints on implementation and access due to significant costs, among other factors. Herein, we evaluated the impact of the growing multispecialty use of RAS on urologic RAS access and outcomes in the past decade.

METHODS

We conducted a retrospective review of all RAS performed by different surgical specialties in two high-volume academic hospitals between 2010 and 2019 (prior to the COVID pandemic). The assessed outcomes included the effect of increased robot access over the years on annual robotic-assisted radical prostatectomy (RARP) volumes, surgical waiting times (SWT), and pathologically positive surgical margins (PSM). Data were collected and analyzed from the robotic system and hospital databases.

RESULTS

In total, six specialties (urology, gynecology, general, cardiac, thoracic, and otorhinolaryngologic surgery) were included over the study period. RAS access by specialty doubled since 2010 (from three to six). The number of active robotic surgeons tripled from seven surgeons in 2010 to 20 surgeons in 2019. Moreover, there was a significant drop in average case volume, from a peak of 40 cases in 2014 to 25 cases in 2019 (p=0.02). RARP annual case volume followed a similar pattern, reaching a maximum of 166 cases in 2014, then declining to 137 cases in 2019. The mean SWT was substantially increased from 52 days in 2014 to 73 days in 2019; however, PSM rates were not affected by the reduction in surgical volumes (p<0.05).

CONCLUSIONS

Over the last decade, RAS access by specialty has increased at two Canadian academic centers due to growing multispecialty use. As there was a fixed, single-robotic system at each of the hospital centers, there was a substantial reduction in the number of RAS performed per surgeon over time, as well as a gradual increase in the SWT. The current low number of available robots and unsustainable funding resources may hinder universal patient access to RAS.

Sacral neuromodulation in the golden years: Treatment outcomes in elderly 75 years and older

INTRODUCTION

Despite high prevalence and increased severity and burden of overactive bladder (OAB) and fecal incontinence (FI) in the elderly, sacral neuromodulation (SNM) is often overlooked as a potential treatment option for this demographic. In this study, we report the outcomes of SNM in patients aged 75 years or older at the time of surgery.

METHODS

We conducted a retrospective cohort study of patients who underwent SNM implantation between 2013 and 2022 performed by a single, high-volume urologist at a tertiary center. Success, complication, and adjunct therapy rates were analyzed by Fisher's or Wilcox rank-sum test as appropriate. We compared outcomes between patients aged 75-79 years and octogenarians.

RESULTS

Of 632 patients, 50 were ≥75 years. Patients had a mean age of 78.4±2.6 years and were predominantly female (84%). The indications for SNM were 66% OAB, 16% FI, 16% non-obstructive urinary retention, and 4% pelvic pain. Within the first year, 94% of patients reported satisfaction and improvement in symptoms, while 76% continued to experience improvement beyond one year. SNM insertion led to reduced oral medication use from 68% to 24% (p<0.0001). The complication rate was 16% and mostly included device pain. No significant difference was observed in treatment success, complication, or adjunct therapy rate between age groups.

CONCLUSIONS

SNM is a safe and effective option in well-selected patients over the age of 75 years. Treatment success rate is comparable to younger cohorts. Advanced age should not preclude third-line therapy options in this population.

Use of the Schelin Catheter for transurethral intraprostatic anesthesia prior to Rezūm treatment

Minimally invasive surgery techniques (MIST) have become newly adopted in urological care.  Given this, new analgesic techniques are important in optimizing patient outcomes and resource management. Rezūm treatment (RT) for BPH has emerged as a new MIST with excellent patient outcomes, including improving quality of life (QoL) and International Prostate Symptom Scores (IPSSs), while also preserving sexual function.  Currently, the standard analgesic approach for RT involves a peri-prostatic nerve block (PNB) using a transrectal ultrasound (TRUS) or systemic sedation anesthesia.  The TRUS approach is invasive, uncomfortable, and holds a risk of infection.  Additionally, alternative methods such as, inhaled methoxyflurane (Penthrox), nitric oxide, general anesthesia, as well as intravenous (IV) sedation pose safety risks or mandate the presence of an anesthesiology team.  Transurethral intraprostatic anesthesia (TUIA) using the Schelin Catheter (ProstaLund, Lund, Sweden) (SC) provides a new, non-invasive, and efficient technique for out-patient, office based Rezūm procedures.  Through local administration of an analgesic around the prostate base, the SC has been shown to reduce pain, procedure times, and bleeding during MISTs.  Herein, we evaluated the analgesic efficacy of TUIA via the SC in a cohort of 10 patients undergoing in-patient RT for BPH.

Comparing prostatic artery embolization to surgical and minimally invasive procedures for the treatment of benign prostatic hyperplasia: a systematic review and meta-analysis

BACKGROUND

To summarize current evidence to report a comparative systematic review and meta-analysis of prostatic artery embolization (PAE) with transurethral resection of the prostate (TURP) and open simple prostatectomy (OSP) for the treatment of benign prostatic hyperplasia (BPH).

METHODS

A systematic literature search was performed to identify studies published from inception until August 2021. The search terms used were (prostate embolization OR prostatic embolization) AND (prostatic hyperplasia OR prostatic obstruction) as well as the abbreviations of PAE and BPH. Risk of bias was assessed using the Cochrane Risk of Bias tool for randomized controlled trials (RCTs) and the Risk of Bias in Non-randomized Studies-of Interventions (ROBINS-I) tool for observational studies. Random-effects meta-analysis was performed using Revman 5.4.

RESULTS

Seven studies were included with 810 patients: five RCTs and one observational study compared PAE with TURP, and one observational study compared PAE with OSP. The included studies had considerable risk of bias concerns. TURP and OSP were associated with more statistically significant improvements in urodynamic measures and BPH symptoms compared to PAE. However, PAE seems to significantly improve erectile dysfunction compared to OSP and improve other outcome measures compared to TURP, although not significantly. PAE appeared to reduce adverse events and report more minor complications compared with TURP and OSP, but it is unclear whether PAE is more effective in the long-term.

CONCLUSION

PAE is an emerging treatment option for patients with symptomatic BPH who cannot undergo surgery or have undergone failed medical therapy. Overall, PAE groups reported fewer adverse events. Future ongoing and longer-term studies are needed to provide better insight into the benefit of PAE compared to other treatment options.

Peri-prostatic nerve block using Clarius EC7 HD₃ handheld ultrasound guidance

Transrectal ultrasound (TRUS) is a common modality used during urological procedures that require real-time visualization of the prostate, such as prostate biopsy and peri-prostatic nerve blocks (PNB) for surgical procedures. Current practice for TRUS-guided PNB requires use of costly, fixed, and non-portable ultrasound machinery that can often limit workflow. The Clarius endocavity EC7 probe, a digital, handheld and pocket-sized endocavity ultrasound (US) device, is an alternative, portable technology which was recently shown to accurately visualize and measure prostate dimensions and volume. Moreover, in recent years, there has been a renaissance of office-based treatments for minimally invasive surgical therapies (MIST) for the treatment of benign prostate hyperplasia (BPH). More specifically, the Rezūm procedure has been demonstrated to offer men a short, outpatient therapy with excellent 5-year outcomes in durability and preservation of antegrade ejaculation. While other anesthetic techniques have been described for Rezūm, including inhaled methoxyflurane (Penthrox), nitrous oxide, IV sedation and general anesthesia (which often mandate the presence of an anesthesiology team), US-guided local blocks offer the urologist an independent method for pain management. While most urologists may not have direct access to expensive, cart-based ultrasound systems, point of care ultrasound (POCUS) technology, such as Clarius (Vancouver, BC, Canada) and Butterfly (Butterfly Network, Inc, Guilford, CT, USA), can provide high-resolution imaging in combination with smart phone technology. Herein, we sought to describe the technique for using Clarius EC7 for TRUS-guided PNB and its use in urological application with the Rezūm BPH procedure.

A scoping review of office-based prostatic stents: past, present, and future of true minimally invasive treatment of benign prostatic hyperplasia

PURPOSE

To conduct a scoping review of the existing literature and recent developments on prostatic stents for the treatment of benign prostatic hyperplasia (BPH).

METHODS

A comprehensive search was performed on Embase, MEDLINE, and Web of Science to identify English literature on prostatic stents for the treatment of BPH. Additional studies and upcoming devices were identified through grey literature search and expert consultation. Study characteristics and stent information were extracted and tabulated narratively.

RESULTS

Of the 1171 search results, 64 studies were included in this review. iTiND was the prostatic stent with the most long-term evidence. iTiND is a safe and effective minimally invasive treatment for BPH that preserves sexual function. Adverse events are mild and transitory. Emerging stents (e.g. Zenflow, Butterfly, Urocross, and Exime) had 7/64 eligible studies, where no studies had long-term follow-up. These newer stents show promising results for quality of life and BPH symptom management; however, long-term monitoring and head-to-head comparisons are needed.

CONCLUSION

Over the last 50 years, prostatic stents have evolved and demonstrated improved clinical efficacy. iTiND provides a safe and effective outpatient treatment of LUTS secondary to BPH preserving erectile and ejaculatory function. Emerging prostatic stents are a promising, effective, and safe intervention in well-selected patients interested in its benefits.

Aquablation in Patients on Antithrombotics: Assessment of Safety, Postoperative Bleeding Rates and Clinical Outcomes

OBJECTIVE

To analyze the impact of perioperative antithrombotic use on the bleeding outcomes following Aquablation.

METHODS

One hundred sixteen men with who underwent Aquablation as part of the WATER prospective trial (NCT02505919) were assigned to 2 groups based on perioperative antithrombotic status. Antithrombotic cessation and restart timing were based on the surgeon's discretion. Methods of achieving intraoperative hemostasis consisted of no-cautery balloon tamponade or cautery. Primary endpoints included immediate postoperative hematuria rates and changes in hemoglobin. Secondary endpoints included 90-day bleeding complications and nonbleeding postoperative adverse events.

RESULTS

Forty-one men took antithrombotic medications in the perioperative period while 75 men had no antithrombotic medication. Preoperative hemoglobin levels were comparable between both groups. Postoperative hemoglobin change from baseline (drop of 1.8 ± 1.5 g/dL among the antithrombotic group vs 1.8 ± 1.7 g/dL among the antithrombotic-naïve group) did not differ between both groups (P = .896). In total, 4 (9.8%) men in the antithrombotic group and 4 (5.3%) patients in the antithrombotic-naïve group experienced a Clavien-Dindo grade 1 complication (P = .451) in the 3-month postoperative period. Eight (19.5%) patients in the antithrombotic group and 11 (14.7%) patients in the antithrombotic-naïve group experienced a Clavien-Dindo grade 2 complication (P = .601), none of which is associated with bleeding in both groups. No men in either group demonstrated de novo erectile dysfunction. One patient (2.4%) in the antithrombotic group and none in the antithrombotic-naïve group required blood products (P = .353).

CONCLUSION

Aquablation demonstrates comparable postoperative bleeding outcomes and other adverse effects for men with benign prostatic hypertrophy who are on antithrombotic therapy.

Procedural Intervention for Benign Prostatic Hyperplasia in Men ≥ Age 70 Years - A Review of Published Literature

Objective

We set out to review studies reporting on the use of surgical intervention to treat Benign Prostatic Hyperplasia in elderly men ≥70 years of age.

Methods

A systematic literature search was conducted using Scopus, PubMed-MEDLINE, Cochrane, and Wiley Online Library databases including studies published between January 2012 through December 2022. This 10-year interval was chosen given the recent plethora of new modalities that have entered the BPH armamentarium, many of which have been marketed as appropriate for older and high-risk patients. The following database search words were used either individually or in conjunction: "BPH", "elderly", "surgical", "ablation", "resection", "embolization", and "aging".

Results

We identified 28 studies for inclusion in this review. The pros and cons of these modalities are presented, specifically as applicable to an older and higher risk population.

Conclusion

There are a wide variety of surgical procedures available for surgically treating BPH in elderly men with varying states of health. Each of these comes with different risks and benefits, supporting that individualized approaches are important. Long-term data and further studies comparing modalities, specifically as regards the elderly and frail, would enhance our approaches to BPH treatment in this patient population.

Performing urological inpatient procedures as same-day procedures during the COVID pandemic A retrospective feasibility study

INTRODUCTION

In line with Canadian provincial directives due to the COVID-19 pandemic, certain elective urologic surgical cases that are normally performed as inpatient procedures were performed as same-day discharge procedures to reduce hospitalization and the usage of scarce healthcare resources. Since the pandemic, we began performing laser enucleation of the prostate (LEP), robotic-assisted radical prostatectomy (RARP), and percutaneous nephrolithotomy (PCNL ) as outpatient surgeries. This was supported by recent evidence demonstrating the safety and feasibility of performing these minimally invasive surgeries as same-day procedures. As such, we sought to retrospectively evaluate the clinical outcomes and safety during the COVID-19 era at our institution for same-day discharge LEP, RARP, and PCNL procedures.

METHODS

All patients operated for LEP, RARP, or PCNL between May 2020 and March 2022 at two academic institutions were included. Surgeries were classified as planned same-day discharge or inpatient surgery. Same-day discharge patients were compared to inpatients for each procedure type. This comparison assessed the occurrence of same-day failure, postoperative complications, and re-admission rates at 30 days. This study was approved by the scientific ethics committee of the Centre de Recherche de l'Université de Montréal (CRCHUM).

RESULTS

A total of 413 subjects were included in this study. Among LEP patients (n=169), 104 (62%) were identified as same-day procedures and 65 (38%) were inpatient. Among RARP patients (n=194), 46 (24%) were identified as same-day procedures and 148 (76%) inpatient. Among PCNL patients (n=50), 38 (76%) were identified as same-day procedures and 12 (24%) were inpatient. Of the patients who underwent planned same-day LEP, RARP, and PCNL, 77.9%, 73.9%, and 71.1% were successfully discharged home, respectively. Patients who underwent LEP as inpatients had a higher incidence of overall postoperative complications compared to same-day LEP (23.1% vs. 8.7%, p=0.017). The rates of 30-day emergency department (ED ) visits and hospital re-admission were similar between inpatient and same-day LEP (9.2% vs. 3.8%, p=0.27; and 4.6% vs. 1.0%, p=0.32, respectively). Inpatient RARP, however, was associated with more 30-day ED visits compared to same-day procedures (17.4% vs. 4.1%, p<0.01). No statistically significant differences were found for postoperative complications (15.2% vs. 6.1%, p=0.097) and re-admission rates (1.4% vs. 4.3%, p=0.51). There were no significant differences on overall postoperative complications, 30-day ED visits, and re-admission rates in inpatient vs. same-day PCNL.

CONCLUSIONS

Our results suggest that same-day discharge for LEP, RARP, and PCNL is safe and feasible in select patients, with an acceptable complication rate. These results should be validated in a larger, prospective clinical trial comparing same-day and inpatient procedures.

Aquablation versus TURP: 5-year outcomes of the WATER randomized clinical trial for prostate volumes 50-80 mL

INTRODUCTION

To report the 5-year efficacy and safety of Aquablation compared with transurethral resection of the prostate for the management of lower urinary tract symptoms secondary to benign prostatic hyperplasia in men with prostate volumes 50-80 mL.

MATERIALS AND METHODS

In a large double-blinded, multicenter, and prospective randomized controlled trial, 96 randomized men with 50-80 mL prostates who underwent Aquablation or transurethral prostate resection were prospectively identified for subgroup analysis. Follow up was performed for up to 5 years. The primary efficacy endpoint was the reduction in International Prostate Symptom Score (IPSS) at 6 months. The primary safety endpoint was the occurrence of Clavien-Dindo (CD) postoperative complications grade 1 persistent and grade 2 or higher at 3 months.

RESULTS

Both groups had comparable baseline characteristics. Reduction in IPSS score was significantly higher in the Aquablation group across 5 years of follow up (-14.1 vs. -10.8, p = 0.02). The Aquablation group achieved a significantly lower rate of CD1P and CD2 or higher events at 3 months follow up (risk difference of -23.1%). Among recorded adverse events, de novo postoperative ejaculatory dysfunction was notably lower in Aquablation (risk difference of -21.9%), while the risk of bleeding remained similar after 6 months. The surgical and medical retreatment rate at 6 months was also lower in Aquablation (risk difference of -14.4%).

CONCLUSIONS

In the 50-80 mL prostate volume subgroup, Aquablation yields superior long-term symptom relief and lower complication rates than standard transurethral resection, with notably lower rates of ejaculatory dysfunction. This further supports the adoption of Aquablation for men with medium-sized prostates.

Evaluation of Canadian urology residency and fellowship program websites

Introduction: There is growing use of online resources in the postgraduate medical education application process to provide applicants program-specific details, thus allowing for informed decision-making. Given the variability and non-standardized electronic training descriptions and objectives, our goal was to assess the availability of program information through program websites for both residency and fellowship urology programs across Canada. Methods: Using the Canadian Residency Matching Service (CaRMS) and the Canadian Urological Association (CUA) websites, we compiled a list of all Canadian urology residency and fellowship programs. We reviewed all programs’ website using a 40-item tool based on seven subcategories, including education, application process, faculty information, trainee/fellow information, research and extra-curricular activities, wellness, and both benefits and career planning. Each website was reviewed by two trained reviewers. Any inter-reviewer discrepancy was resolved by a third-party reviewer. Results: Among 13 Canadian urology residency programs, all had program websites and met 48% of the criteria evaluated. None of the residency program websites reported information on work hours, surgical caseload statistics, or equity diversity and inclusion/community initiatives. Among 37 Canadian urology fellowship programs, 10 programs did not have websites, and the remaining 27 program websites met 28% of the criteria evaluated. Scores were highest for the application process subcategory, while scores were lowest for the wellness and benefits/career planning subcategories among both residency and fellowship programs. Conclusions: With growing reliance and dependence on web resources to access residency and fellowship program information, there is a clear need to standardize and improve Canadian training websites for prospective applicants.

Treating LUTS in Men with Benign Prostatic Obstruction: A Review Article

Benign prostatic obstruction (BPO) is a prevalent condition that affects men, primarily toward their old age. The condition is often accompanied by lower urinary tract symptoms (LUTS), which can significantly impair a patient's quality of life and lead to other medical complications. Accurate diagnosis of BPO is essential for effective management of complications secondary to BPO, and treatment plans should be tailored patients, and occasionally according to surgeon experience. As such, this literature review aims to analyze the current available data on male LUTS secondary to BPO by providing a comprehensive overview of relevant studies, as well as the surgical and medical management guidelines from the Canadian Urological Association (CUA), American Urological Association (AUA), and European Association of Urology (EAU). By synthesizing the existing literature, this review purports to summarize the current body of knowledge surrounding BPO and male LUTS, and support healthcare providers in making informed decisions about the management of male LUTS secondary to BPO, ultimately improving patient outcomes and quality of life.

Aquablation Therapy in Large Prostates (80-150 mL) for Lower Urinary Tract Symptoms Due to Benign Prostatic Hyperplasia: Final WATER II 5-Year Clinical Trial Results

PURPOSE

We report 5-year safety and efficacy outcomes of the Aquablation procedure for the treatment of men with symptomatic benign prostatic hyperplasia and large-volume prostate glands.

MATERIALS AND METHODS

A total of 101 men with moderate to severe benign prostatic hyperplasia symptoms and prostate volumes between 80 and 150 mL underwent a robotic-assisted Aquablation procedure in a prospective multicenter international trial (NCT03123250). Herein we report the final 5-year results.

RESULTS

The study successfully met its safety and efficacy performance goal, which was based upon transurethral resection of the prostate outcomes typically done in smaller prostates, at 3 months. Mean prostate volume was 107 mL (range 80-150) at baseline. Patient symptoms showed a significant improvement where the mean (SD) International Prostate Symptom Score of 22.6 (6.4) at baseline to 6.8 (4.6) at 5 years, resulting in a change score of 15.9 (7.7, P < .001). Uroflowmetry measurements also demonstrated improvement where the mean maximum urinary flow rate increased from 8.6 (SD 3.4) to 17.1 (9.8) mL/s at 5 years, resulting in a change score of 9.2 (11.1) mL/s at 5 years (P < .001). A regression analysis evaluating change in PSA as a function of baseline PSA across all time points out to 5 years resulted in a 50% reduction. A prespecified subgroup analysis using a baseline prostate volume cutoff of 100 mL showed no difference in efficacy outcomes through 5 years. Freedom from a secondary benign prostatic hyperplasia procedure at 5 years was 96.3% based on Kaplan-Meier.

CONCLUSIONS

At 5-years of prospective follow-up, the Aquablation procedure was shown to be safe with durable efficacy and low rates of retreatment in men with large prostates (80-150 mL).

Change in Prostate Volume and Symptom Improvement in Men Treated With Rezūm Water Vapor Therapy

OBJECTIVE

To evaluate the change in prostate volume (PV) and relationship to improvement in urinary symptom scores following Rezūm therapy.

METHODS

Quality of life outcomes and PV were assessed at baseline and 12months postprocedure. Percent change from baseline in outcomes and PV were calculated, as was the number of Rezum injection to baseline PV ratio. Association between total number of injections and changes in outcomes and PV were evaluated using linear regression models.

RESULTS

A total of 49 men (mean age=67.8; standard deviation=9.4) underwent the procedure between April 2019 and September 2020, with a median baseline PV of 71.5 cc (range 24-150) and median number of vapor injections of 11.0 (range 4-21). At 12months, the median percent change in PV was - 34.0% (interquartile range: -49.2%, -16.7%), with 45/49 (91.8%) patients having reduced volume. Among the 45 patients with reduced volume at 12months, every 10% increase in volume reduction was associated with a 7.5% (95% confidence interval, 1.4%-13.6%; P = .02) improvement in the International Prostate Symptom Score. There was no significant association between total number of injections or injection to baseline volume ratio and change in PV.

CONCLUSION

In this cohort of men treated with Rezūm therapy for benign prostatic hyperplasia, it was demonstrated that there is a correlation between greater PV reduction and greater symptomatic improvement. This study showed no association between more injections or the ratio of injections to PV changes, refuting the claim that more injections are better.

Litigation associated with 5-alpha-reductase-inhibitor use: A Canadian legal database review

INTRODUCTION

5α-reductase inhibitors (5ARI) are commonly prescribed medications. There is ongoing controversy about the adverse events of these medications. The aim of this study is to characterize lawsuits in Canada involving medical complications of 5ARIs use.

MATERIALS AND METHODS

Legal cases were queried from CanLII. Cases were included if they involved a party taking a 5ARI who alleged an adverse event. Relevant full cases were retained, and pertinent characteristics were extracted with the help of a legal expert.

RESULTS

Our deduplicated search yielded 67 unique legal documents from December 2013 to February 2019. Twelve of these documents met the inclusion criteria (representing 3 cases, considering each case had several hearings). The medical complaints filed by the plaintiffs were all related to medication side effects (n = 3, 100%). The plaintiffs were commonly patients themselves. Defendants were exclusively pharmaceutical companies. Persistent erectile dysfunction after stopping the medication was cited as a side effect in all complaints. The prescriptions were made for male pattern hair loss (n = 3, 100%) in all cases. All cases represent class actions brought by the plaintiffs, and they have been certified by their respective court. However, the cases are still ongoing.

CONCLUSION

While 5ARI use has been linked to undesired sexual side effects, there have been few litigations on this issue in Canada. Persisting sexual dysfunction after stopping the medication is the only complaint presented in legal action. To date, no judgment against a physician or pharmaceutical company was identified. Cases are still ongoing.

How I Do It: Optilume BPH catheter system

Benign prostatic hyperplasia (BPH) is a common and progressive disease affecting aging men which has a significant impact on quality of life. The Optilume BPH Catheter System (Optilume BPH) is a prostatic dilation system that combines balloon dilation with a localized transfer of paclitaxel to maintain long term patency. Optilume BPH can be deployed using standard rigid cystoscopy without general anesthesia in an office setting. Prospective data indicate that Optilume BPH has favorable functional and sexual patient outcomes. Readers will familiarize themselves with Optilume BPH, significant historical studies and the technique for deploying Optilume BPH.

Enterococcal Urinary Tract Infections: A Review of the Pathogenicity, Epidemiology, and Treatment

Urinary tract infections (UTIs) are among the most common causes of infections worldwide and can be caused by numerous uropathogens. Enterococci are Gram-positive, facultative anaerobic commensal organisms of the gastrointestinal tract that are known uropathogens. Enterococcus spp. has become a leading cause of healthcare associated infections, ranging from endocarditis to UTIs. In recent years, there has been an increase in multidrug resistance due to antibiotic misuse, especially in enterococci. Additionally, infections due to enterococci pose a unique challenge due to their ability to survive in extreme environments, intrinsic antimicrobial resistance, and genomic malleability. Overall, this review aims to highlight the pathogenicity, epidemiology, and treatment recommendations (according to the most recent guidelines) of enterococci.

The role of quantitative MRI-based prostate zonal parameters in predicting clinically significant prostate cancer: A U.S. cohort

INTRODUCTION

We aimed to investigate the clinical utility of quantitative prostatic zonal measurements on in multiparametric magnetic resonance imaging (mpMRI) for the predication of clinically significant prostate cancer (csPCa).

METHODS

A retrospective, single-institution study included 144 men who underwent mpMRI from 2015- 2017. Prostate zone parameters were measured on mpMRI. Correlation and multivariable analysis evaluated relationship between prostate zone parameters and the presence of csPCa.

RESULTS

The mean age was 66.9±7.8 years old. The median (interquartile range [IQR]) prostate volume and prostate-specific antigen (PSA) were 51.6 ml (37.1-74.5) and 6.1 ng/ml (4.5-8.2), respectively. Men with csPCa had significantly smaller total prostate volume (TPV), transitional zone volume (TZV), and transitional zone thickness (TZT), and larger transitional zone density (TZD) compared to those without PCa; however, on multivariate variable analysis, only TZD maintained significance. TZD had a comparable area under the curve to PSA density (PSAD) and PSA (0.74 vs. 0.73 vs. 0.60, respectively). Subgroup analysis of men with PCa, PSAD and TZD were significantly higher in men with Gleason grade group (GG) ≥2 compared to those with GG <2 (p=0.002); however, this significance is not maintained on logistic regression in predicting GG.

CONCLUSIONS

Quantitative features of prostate zones on MRI may aid in identifying better predictors of csPCa. Zonal-based PSA density (TZD) may be a useful marker in identifying csPCa. Further exploration is needed to understand the clinical application of larger TZV in men with csPCa compared to those with insignificant disease.

Cost-utility of minimally invasive therapies vs. pharmacotherapy as initial therapy for benign prostatic hyperplasia A Canadian healthcare payer perspective

INTRODUCTION

Recently, minimally invasive surgical therapies (MIST s) have become an alternative to surgery or pharmacotherapy to manage benign prostatic hyperplasia (BPH ). This study evaluated the cost-utility of water vapor thermal therapy (WVTT ) and prostatic urethral lift (PUL) compared to pharmacotherapy as initial treatment for patients with moderate-to-severe BPH.

METHODS

In this model-based economic evaluation, we simulated BPH progression in men (mean age 65 years, average International Prostate Symptom Score 16.6) over their lifetime and estimated healthcare costs (from the Canadian healthcare payer perspective) per quality-adjusted life year (QALY), discounted at 1.5% annually. In the model, men could receive up to three lines of therapy: 1) initial pharmacotherapy with MIST as second-line, and TURP or pharmacotherapy as third-line; 2) initial MIST (WVTT or PUL) with MIST again, TURP, or pharmacotherapy as second-line, and TURP as third-line. The model was populated using data from the published literature.

RESULTS

The expected lifetime QALYs and costs were 15.50 QALYs and $14 626 for initial treatment with WVTT, 15.35 QALYs and $11 795 for pharmacotherapy followed by WVTT, 15.29 QALYs and $13 582 for pharmacotherapy followed by PUL, and 15.29 QALYs and $19 151 for initial treatment with PUL. Strategies involving PUL procedures were dominated by strategies involving WVTT. The incremental cost per QALY gained was $18 873 for initial WVTT compared to initial pharmacotherapy followed by WVTT.

CONCLUSIONS

WVTT appears to be a cost-effective procedure and may be an appropriate first-line alternative to pharmacotherapy for patients with BPH and prostate volume less than 80 cm3 who seek faster improvement and no lifelong commitment to daily medications.

The impact of 5-ARI on perioperative and functional outcomes of GreenLight PVP: an analysis of the Global GreenLight Group database

INTRODUCTION

  In this study, we sought to investigate the impact of 5-alpha reductase inhibitors (5-ARI) on the perioperative and functional outcomes of 180-Watt XPS GreenLight photovaporization of the prostate (PVP) using a large international database.

MATERIALS AND METHODS

  Data were obtained from the Global GreenLight Group (GGG) database, which includes eight high-volume, experienced surgeons from seven international centers.  All men with established benign prostatic hyperplasia (BPH) with known 5-ARI status who underwent GreenLight PVP using the XPS-180W system between 2011 and 2019 were eligible for the study.  Patients were assigned to two groups based on the preoperative use of 5-ARI.  Analyses were adjusted for patient age, prostate volume, and American Society of Anesthesia (ASA) score.

RESULTS

  We included 3,500 men, of which 1,246 (36%) had preoperative 5-ARI use.  Patients in both groups were similar with regards to age and prostate size.  On multivariable analysis, total operative time was slightly shorter (-3.26 min 95% CI: 1.20 - 5.32, p < 0.01) and required 35.6kJ less laser energy (95% CI: -48.0kJ - -23.3kJ, p < 0.01) for patients on 5ARI compared to those without 5-ARI.  However, no clinically significant difference was appreciated regarding postoperative transfusion rates [OR 0.048 (95% CI -0.82-0.91; p = 0.91)], hematuria rates [OR 0.96 (95% CI 0.72-1.3; p = 0.81)], 30-day readmission rates [OR 0.98 (95% CI 0.71-1.4; p = 0.90)], or overall functional outcomes.

CONCLUSION

  Our findings suggest that preoperative 5-ARI is not associated with any clinically significant different perioperative or functional outcomes for GreenLight PVP using the XPS-180W system.  There is no role for the initiation or discontinuation of 5-ARI prior to GreenLight PVP.

Pharmacotherapy vs. minimally invasive therapies as initial therapy for moderate-to-severe benign prostatic hyperplasia: a cost-effectiveness study

BACKGROUND

Recently, minimally invasive therapies (MITs), such as water vapor thermal therapy (WVTT) and prostatic urethral lift (PUL) have become an alternative to surgery or pharmacotherapy to manage benign prostatic hyperplasia (BPH), offering symptom relief with a favorable safety profile. The objective of this study was to evaluate the cost-utility of MITs (WVTT and PUL) compared to pharmacotherapy as initial treatment for patients with moderate-to-severe BPH.

METHODS

In this model-based economic evaluation we simulated BPH progression in men (mean age 65 years, average International Prostate Symptom Score 16.6) over their lifetime and estimated healthcare costs (from the US public payer perspective) per quality-adjusted life year (QALY), discounted at 3% annually. Various clinical scenarios were evaluated given that most men undergo several lifelong therapies up to surgical intervention and potentially thereafter. As such, in the study model men could receive up to three lines of therapy: (1) initial pharmacotherapy with MIT as second-line, and transurethral resection of the prostate (TURP) or pharmacotherapy as third-line; (2) initial MIT (WVTT or PUL) with MIT again, TURP or pharmacotherapy as second-line, and TURP as third-line. Model was populated using data from the published literature. Probabilistic analyses were performed.

RESULTS

Initial treatment with WVTT led to the highest QALYs (13.05) and the lowest cost ($15,461). The cumulative QALYs and lifetime costs were 12.92 QALYs and $20,280 for pharmacotherapy followed by WVTT, 12.87 QALYs and $22,424 for pharmacotherapy followed by PUL, 12.86 QALYs and $20,930 for initial treatment with PUL. In the cost-utility analysis, WVTT as initial treatment dominated all three strategies, i.e., generated more QALYs at a lower cost.

CONCLUSION

WVTT is an effective and cost-saving procedure, and may be an appropriate first-line alternative to pharmacotherapy for moderate-to-severe BPH patients who seek faster improvement and no lifelong commitment to daily medications.

Safety and efficacy of GreenLight PVP in octogenarians: evaluation of the Global GreenLight Group database

INTRODUCTION

The present study analyzes the largest international GreenLight database, the Global GreenLight Group (GGG), to evaluate the functional and safety profile of GreenLight photoselective vaporization of the prostate (PVP) in octogenarians.

METHODS

The GGG is a database comprised of patients that underwent GreenLight PVP from 2011 to 2019 performed by 8 experienced urologists at 7 international hospitals. Patients 80 years or older at the time of surgery were categorized as octogenarians. They were compared to a similar group of PVP patients below the age of 80.

RESULTS

Among 3,648 patients, 586 men were above the age of 80. Compared to patients under the age of 80, octogenarians had larger prostates (76.0 vs 71.9 ml, p = 0.02) and a lower BMI (25.6 vs 26.7, p = 0.045). Operative time was not significantly longer in octogenarians. The improvement in functional outcomes between 80-year-old patients and control patients was not significantly different at one-year follow-up, with the exception of maximum urinary flow (Q_max) that favoured younger patients (10.3 vs 12.6 ml/s, p = 0.02). The odds of transfusion were greater for older patients [OR 8.2 (95% CI 3.6-18.9, p < 0.01)], but they were not at increased risk of hematuria. Octogenarians had higher readmission rates (23.0 vs 11.9%, p < 0.01).

CONCLUSIONS

GreenLight PVP is a safe option in well-selected octogenarians in a cohort of patients treated by surgeons experienced with the technology. The odds of transfusion were higher in patients over 80, but the absolute risk remains low. The 30-day hospital readmission rate was higher in octogenarians.

Prostatic zonal parameters and lower urinary tract symptoms as quantified via magnetic resonance imaging

INTRODUCTION

Benign prostatic hyperplasia (BPH) is a common diagnosis among aging males; however, the relationship between prostate volume and lower urinary tract symptoms (LUTS) severity is imperfect. The goal of this study was to comprehensively investigate the relationship between various prostate zone-based parameters measured using magnetic resonance imaging (MRI) and LUTS.

METHODS

Data were retrospectively collected for 144 patients who underwent MRI between 2015 and 2017 at a single institution. Prostate volumes were measured on sagittal and axial T2 weighted using the prostate ellipsoid formula.

RESULTS

Only transition zone thickness (TZT) correlated with International Prostate Symptom Score (IPSS) (Pearson's=0.33; p=0.007). The intraprostatic protrusion (IPP) component (rho 0.261; p=0.036), transitional zone volume (TZV) (rho 0.264; p=0.034), and TZT (Pearson's correlation 0.422; p<0.001) all correlated with worsening QoL scores. In total, 97.9% of men had the presence of an IPP (>0 mm) and larger IPPs were found in older men with higher postvoid residual volumes. Larger peripheral zone volume (PZV) (odds ratio [OR] 3.62, 95% confidence interval [CI] 1.07-12.30, p<0.05), TZV (OR 6.00, 95% CI 1.69-21.35, p<0.05), and TZT (OR 4.00, 95% CI 1.17-13.69, p<0.05) were predictive of developing severe LUTS; however, IPP (p=0.122) was not.

CONCLUSIONS

TZV, TZT, and IPP all demonstrated a role in the evaluation of LUTS with predictive capabilities. IPP is very common but not always clinically significant. Clarifying more precise zonal parameters and their relationship with LUTS may ultimately help clinicians guide the need for surgical intervention more precisely.

Age-stratified potency outcomes of bilateral nerve sparing robotic-assisted radical prostatectomy

INTRODUCTION

This study aims to report age-stratified potency outcomes in men undergoing robot-assisted radical prostatectomy (RARP).

MATERIALS AND METHODS

A retrospective review was performed on a database of 1737 patients who underwent RARP for localized prostate cancer between 2007 and 2019. Inclusion criteria consisted of patients undergoing bilateral nerve-sparing RARP. Exclusion criteria were preoperative Sexual Health Inventory for Men (SHIM) score < 17 and postoperative androgen deprivation therapy or radiotherapy. Patients were divided into four cohorts based on age: ≤ 54 years (group 1); 55-59 years (group 2); 60-64 years (group 3) and ≥ 65 years (group 4). Functional outcomes were measured up to 36 months. Kaplan-Meier analysis was performed to compare the time to recovery of potency stratified by age groups using log-rank testing.

RESULTS

A total of 542 patients met the selection criteria. Potency rates were significantly different between groups. Groups 1 through 4 demonstrated potency recovery rates of 64.2%, 52.3%, 36.6% and 20.7% at 1-year follow up, respectively. After 3 years, groups 1 through 4 had potency rates of 77.9%, 67.0%, 50.5% and 35.0%, respectively. Recovery of potency was achieved at a median time after surgery of 199, 340 and 853 days for groups 1-3, respectively. The Cox proportional hazard model showed that older age, higher body mass index (BMI), and lower preoperative SHIM score were associated with significantly higher rates of impotence.

CONCLUSION

This study shows that RARP has acceptable potency outcomes, regardless of age. However, patient factors, including older age and preoperative SHIM were significantly associated with poorer functional recovery. This data is valuable in prognostic evaluation and patient counseling.

Effect of Surgeon and Facility Volume on Outcomes of Benign Prostatic Hyperplasia Surgery: Implications of Disparities in Access to Care at High-Volume Centers

OBJECTIVE

To report the effect of surgeon and facility volume on outcomes of transurethral resection of the prostate (TURP) and laser treatment of benign prostatic hyperplasia (BPH). We also investigate disparities in access to care by identifying demographic predictors of receipt of treatment at high-volume facilities.

METHODS

We used New York State Department of Health Statewide Planning and Research Cooperative System (SPARCS) data. We included 18,041 (41.4%) and 25,577 (58.6%) adult patients that underwent TURP and laser procedures in the outpatient setting between January 2005 and December 2018, respectively. Average annual surgeon and facility volumes were broken down by tertile. The effect of volume on short-term outcomes (30-day and 90-day readmission) was examined using mixed-effect logistic regression models. Cox-proportional-hazard models were used to assess the association between volume and long-term stricture development and reoperation. Demographic predictors of treatment at high-volume facilities were assessed using multinomial logistic regression.

RESULTS

High-volume facilities were more likely to offer laser procedures compared to low-volume facilities. Higher facility and surgeon volume were associated with lower odds of 30 and 90-day readmissions compared to low-volume facilities. There was no difference in reoperation and stricture development between surgeon volume groups. Medicaid insurance, Hispanic ethnicity, and Black race were inversely associated with treatment at high-volume facilities.

CONCLUSION

Higher surgeon and facility volumes were associated with lower odds of readmission. Higher facility volume was associated with lower hazards of reoperation and developing strictures. Medicaid insurance and non-white race were associated with lower odds of treatment at high-volume facilities, highlighting racial and socioeconomic disparities in access to high-volume BPH surgery facilities.

How I Do It: Penthrox in Urology

Penthrox is a portable handheld inhaler that delivers a low dose of methoxyflurane - an anesthetic with analgesic effects, rapid onset of action, and a favorable side-effect profile. It has been widely used for acute pain management in Australia for the past 40 years. Currently, it is approved for use in over 55 countries, including Canada. Prospective randomized studies highlight Penthrox analgesic effectiveness and safety profile for emergency, prehospital and outpatient settings. In addition, the use of multimodal analgesia, specifically Penthrox, can play an important role in the analgesic management of urological procedures, such as prostatic biopsies and office-based minimally invasive surgical therapies. Herein readers will familiarize themselves with Penthrox, significant studies, and technique used for outpatient urological procedures.

Prostatic artery embolization compared to transurethral resection of the prostate and prostatic urethral lift: a real-world population-based study

BACKGROUND

There are growing interests for minimally invasive surgical techniques (MISTs) for the treatment of benign prostatic hyperplasia (BPH)-associated lower urinary tract symptoms (LUTS). Prostatic artery embolization (PAE) uses selective angioembolization of prostatic arteries, thereby reducing size to improve LUTS/BPH. However, real-world data comparing surgical outcomes between MISTs and tissue resective techniques are lacking. We assessed the differences in surgical outcomes between PAE, transurethral resection of the prostate (TURP), and prostatic urethral lift (PUL) in a real-world population for LUTS/BPH.

METHODS

We present an observational population-based study of 12,902 men with BPH in New York State who received PAE, TURP, and PUL in outpatient and ambulatory surgery settings from 2014 to 2018. For short-term outcomes, we report 30-day and 90-day risks of readmission to inpatient and emergency room (ER) with/without complications and compared them across groups using χ² tests and mixed-effect logistic regressions. For long-term outcomes, we report surgical retreatment and stricture rates using Kaplan-Meier failure curves and compared them using Log rank tests and Cox regression models.

RESULTS

Of 12 902 men, 335 had PAE, 11,205 had TURP, and 1362 had PUL. PAE patients had the highest 30-day (19.9%) and 90-day (35.6%) risks of readmission to inpatient or ER (p < 0.01). Non-specific abdominal pain was the main diagnosis associated with 30-day and 90-day readmissions to inpatient or ER after PAE (14.3% and 26.8%, respectively). After 2 years of follow-up, PAE patients had the highest retreatment rate of 28.5% (95%CI 23.7-34.2%) compared to TURP (3.4% (95%CI 3.1-3.8%)) and PUL (8.5% (95%CI 5.6-12.9%)) (p < 0.001).

CONCLUSION

In a real-world population, PAE was associated with the most frequent 30-day and 90-day readmission to inpatient or ER and the highest retreatment rate among all surgical techniques even when controlled for individual patient comorbidities and surgical volume.

Simulation-based prostate enucleation training: Initial experience using 3D-printed organ phantoms

INTRODUCTION

Anatomical endoscopic enucleation of the prostate (AEEP) is an effective treatment for benign prostatic hyperplasia (BPH); however, there is controversy regarding the difficulty of learning such a technique. Simulation-based training can mimic real-life surgeries and help surgeons develop skills they can transfer to the operating room, thereby improving patient safety. This study aimed to evaluate the validity of a novel organ phantom for use in AEEP simulation training.

METHODS

Participants performed AEEP on organ phantom simulators during a Masterclass using one of three energy modalities: holmium:YAG laser, thulium fiber laser, or bipolar energy. The organ phantom is composed of hydrogels and uses 3D molds to recreate prostatic tissue. Participants completed a questionnaire assessing content validity, face validity, feasibility, and acceptability of using the prostate organ phantom.

RESULTS

The novice group consisted of 13 urologists. The median number of AEEP previously performed was 0 (interquartile range [IQR] 0-2). Two experts in AEEP (surgeons having performed over 100 AEEP interventions) also participated. All participants agreed or strongly agreed that there is a role for simulators in AEEP training. Participants positively rated the overall operative experience (7.3/10). Morcellation (4.7/10) and hemostasis (3.1/10) were deemed the least realistic steps. All participants considered it feasible to incorporate this organ phantom into training programs and 92.9% agreed that it teaches skills transferrable to the operating room.

CONCLUSIONS

This study has established content and face validity for AEEP with three different energy sources for an organ phantom. Participants considered its use both feasible and appropriate for AEEP training purposes.

Efficacy and safety of methoxyflurane (Penthrox) for pain control during water vapor thermal therapy (Rezum) for benign prostatic enlargement

INTRODUCTION

The safety and efficacy of low dose methoxyflurane disposable inhaler (Penthrox) was assessed in this study of men undergoing Rezum water vapor thermal therapy (WVTT).

MATERIAL AND METHODS

An open-labeled, single-center study was conducted to demonstrate the safety and efficacy of using methoxyflurane inhaler during a Rezum procedure. Patients assessed current pain intensity using a 10-point Visual Analog Scale (VAS) of Pain at 4 timepoints including (1) before any medication, (2) initially after insertion of the rigid cystoscope and before any Rezum treatment, (3) immediately after final injection of Rezum treatment and (4) at discharge. Patients were asked to fill out the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4) and one question about pain relief at discharge. Treating physician also completed the TSQM 1.4.

RESULTS

Ten patients were recruited. Median prostate volume was 53.4 cc (range 24-158 cc). Patients received a median of 10.5 Rezum injections, with a median procedure time of 4.5 minutes. Median VAS scores were 0, 0.1, 0 (primary efficacy outcome) and 0 (out of scale of 10) at the 4 timepoints, respectively. TSQM scores on effectiveness, side effects, convenience and global median satisfaction rated by patients were respectively 69.4, 100.0, 77.8 and 82.1 (out of scale of 100). Treatment satisfaction on pain relief was rated as 4.0 (very good). There were no observed adverse events.

CONCLUSIONS

Methoxyflurane inhaler (Penthrox) was low cost, rapid, feasible and easy to administer as a pain management strategy for Rezum therapy. Further data from a larger comparative study will be conducted.

Aquablation Outcomes in Men With LUTS Due to BPH Following Single Versus Multi-pass Treatments

OBJECTIVE

To determine whether existing data support the use of multiple passes in Aquablation for LUTS due to BPH.

METHODS

Data were obtained from 2sources. The WATER trial (NCT02505919) is a prospective, multicenter, double-blind, randomized controlled trial of Aquablation vs TURP in prostate volumes of 30 - 80 ml. The WATER II trial (NCT03123250) is a prospective single-arm multicenter trial of Aquablation in prostate volumes of 80-150ml. The number of passes was determined by the procedural data collected and the video recordings of all study cases.

RESULTS

In total, 127 Aquablation subjects underwent a single pass, 90 underwent multiple passes (80 had 2passes and 10 underwent 3passes), and 65 underwent TURP (in WATER only). Men undergoing 2or more passes with Aquablation had larger prostates but few differences in other baseline parameters, including prostate size range. Compared to a single pass, the use of 2or more passes during Aquablation resulted in lower IPSS scores (by ∼4 points, P = .0002) and lower IPSS QoL scores (by ∼0.7 points, P = .0096) at the later timepoints of 24 and 36 months. Similarly, 36-month Qmax values were higher (by ∼5 ml/sec, P = .0220) in those with 2or more passes than in those with 1pass. There was no statistically significant difference in ejaculatory dysfunction between groups.

CONCLUSION

Independent of prostate volume, a multiple treatment pass protocol led to improved voiding outcomes and IPSS improvement.

Age-stratified continence outcomes of robotic-assisted radical prostatectomy

INTRODUCTION

Incontinence after robot-assisted radical prostatectomy (RARP) significantly impacts quality of life. This study aims to compare the age-stratified continence outcomes in Canadian men undergoing RARP.

MATERIALS AND METHODS

A retrospective review was performed on a prospectively maintained database of 1737 patients who underwent RARP for localized prostate cancer between 2007 and 2019. Patients were stratified into five groups based on age: group 1, ≤ 54 years (n = 245); group 2, 55-59 years (n = 302) ; group 3, 60-64 years (n = 386); group 4, 65-69 years (n = 348); and group 5, ≥ 70 years (n = 116). Functional outcomes were assessed up to 36 months. Log-rank and multivariable Cox regression analyses were performed to compare the time to recovery of pad-free continence by age group.

RESULTS

Continence rates of groups 1 to 5 were respectively 90.2%, 79.1%, 80.4%, 71.4%, and 59.8% at 1-year follow up (p < 0.001). After 3 years, groups 1 through 5 had continence rates of 97%, 91.7%, 89.3%, 81.4%, and 77.6%, respectively (p < 0.001). Median time to recovery of continence was 58, 135, 140, 152 and 228 days, respectively. Among men who remained incontinent, older patients consistently required more pads. In Cox proportional hazard model, groups 2, 3, 4 and 5 were respectively 33% (p < 0.001), 34% (p < 0.001), 33% (p = 0.001), and 41% (p = 0.005) more likely to remain incontinent compared to group 1.

CONCLUSIONS

Age is associated with significantly lower rates of continence recovery, longer time to recovery of continence, and more severe cases of incontinence after RARP.

The following video Atlas summary reviews all technical elements of the standardized setup, robotic execution, aquablation procedure, and hemostasis for efficient rapid benign prostate hyperplasia treatment.

Use of the penile cuff test to diagnose bladder outlet obstruction: A systematic review and meta-analysis

PURPOSE

Among noninvasive modalities for assessing bladder outlet obstruction (BOO), the penile cuff test (PCT) is the most used in clinical practice. The purpose of this review was to evaluate the performance of PCT in diagnosing and managing BOO.

MATERIALS AND METHODS

PubMed, Scopus, CINAHL, Embase, Cochrane Library, and Web of Science were searched for studies investigating use of PCT for BOO. Studies evaluating diagnostic parameters, inter-observer agreements, or treatment outcomes using PCT were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol was followed (PROSPERO ID: CRD42022300047). A proportional meta-analysis was done for diagnostic accuracy proportions. The Egger's and the Begg-Mazumdar rank-correlation tests were used to assess publication bias. Risk of bias was assessed using the Gradings of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria.

RESULTS

Of the 272 articles retrieved, 17 were included in qualitative synthesis and meta-analysis was performed on five studies (comprising 448 patients). Two studies evaluating inter-observer agreement demonstrated 95% agreement and five studies evaluating procedures reported a 66%-80% surgical success rate on obstructed patients using PCT. From the proportional meta-analysis, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 0.85 (95% CI 0.71-0.95) 0.78 (95% CI 0.67-0.87), 0.74 (95% CI 0.52-0.91), and 0.87 (95% CI 0.73-0.96), respectively. Publication bias was noted for PPV but not for sensitivity, specificity, or NPV. Based on the GRADE criteria, there were two low, six moderate, and nine high-quality studies.

CONCLUSIONS

PCT performs sufficiently in diagnosing and managing BOO. However, due to variability in obstruction criteria assessment, more studies comparing diagnostic criteria are warranted.

Global experience and progress in GreenLight-XPS 180-Watt photoselective vaporization of the prostate

PURPOSE

To evaluate changes in global perioperative data of GreenLight-XPS 180-Watt photo-selective vaporization of the prostate (GL-XPS) of the Global Greenlight Group (GGG) database.

METHODS

3441 men, who underwent GL-XPS for symptomatic BPH between 2011 and 2019 at seven high volume international centers, were included. Primary outcome measurements were operative time (OT; min), effective laser time (LT; min of OT), as well as intraoperative and postoperative adverse events (AEs), all analyzed by year of surgery (2011-2019) and prostate volume (PV) group (< 80 ml vs. 80-150 ml vs. > 150 ml).

RESULTS

The median age was 70 years (interquartile range 64-77), the median PV was 64 ml (IQR 47-90). The OT and LT slightly increased but stayed highly efficient all in all. Median OT was 60 min (IQR 45-83) and LT was 33 min (IQR 23-46). Median energy use was 253 kJ (IQR 170-375) with an energy density of 3.94 kJ/ml (IQR 2.94-5.02). The relative probability of perioperative AEs decreased by 17% each year (p < 0.001). The relative probability of perioperative transfusion dropped significantly from 2% in 2011 to 0% in 2019 (p = 0.007). The early postoperative complications (within 30 days after surgery) decreased significantly from 48.8% (n = 106) in 2011 to 24.7% (n = 20) in 2019 (p > 0.001).

CONCLUSION

These findings from the GGG demonstrate significant improvement secondary to growing experience with GL-XPS between 2011 and 2019 in intraoperative AEs, including transfusions, and postoperative AEs. While staying highly efficient in OT and LT of GL-XPS within a 9-year period of experience.

Micro-cost analysis of single-use vs. reusable cystoscopy in a single-payer healthcare system

Introduction: Single-use flexible diagnostic cystoscopy has recently been developed with comparable functionality to reusable cystoscopes. Prior studies have demonstrated considerable upfront costs of reusable cystoscopy. The objective of this study was to compare costs of reusable cystoscopy to single-use cystoscopy in a single-payer, socialized healthcare system. Methods: A retrospective micro-cost analysis of reusable cystoscopy in a combined inpatient and outpatient setting at a single institution was performed. The cost analysis was divided into capital, maintenance, reprocessing, and labor. Annual costs were averaged over two fiscal years. Costs were amortized over 5- and 10-year basis as appropriate. The results were compared to theoretical costs of single-use cystoscopes. Results: There were 3415 annual average cystoscopy cases with 171 cases per reusable cystoscope. The capital, maintenance, reprocessing, and labor costs of reusable cystoscopy are $96 000, $99 867, $247 855, and $65 317, respectively. The total annual costs per case for reusable and single-use cystoscopy are $149.06 and $245.57, respectively. The costs of reusable cystoscopy decrease with the number of procedures per year and intersect the costs of single-use cystoscopes at 1265 procedures per year. All costs are CAD. Conclusions: The cost-effectiveness of reusable cystoscopes is dependent on cystoscopy volume due to considerable upfront costs. Single-use cystoscopes are more cost-effective if the total number of cases performed is less than 1265 per year. Additional investigation into the cost-effectiveness of single-use cystoscopes as supplements in the outpatient setting or primary endoscopes in inpatient/emergency settings should be performed.

Rezūm therapy for ≥ 80 ml benign prostatic enlargement: a large, multi-center cohort study

OBJECTIVE

The purpose of this study was to evaluate the efficacy and safety of Rezūm therapy in benign prostatic hyperplasia (BPH) patients with prostates ≥ 80 ml.

METHODS

A prospective registry was established at two high-volume Canadian centers. Patients had baseline medical history documented, and uroflowmetry and questionnaires recorded over 12 months.

RESULTS

83 patients (median age: 69.2 years, IQR 63.2, 74.8) with a prostate size ≥ 80 ml were included. Median prostate volume was 100.0 ml (IQR 88.5, 115.0) and 65% had a median lobe. 21 patients had prior urinary retention. Median number of injections was 13 (IQR 11, 15). Median catheterization length was 9 days (IQR 7, 14). IPSS improved by 24%, 57%, and 59% at 1, 3, and 12 months, respectively (p<0.001). QoL scores improved by 27%, 56%, and 70% at these same timepoints (p<0.001). Qmax improved by 55% at 3 months (p=0.002) and 59% at 12 months, and PVR improved by 58% at 3 months (p=0.006). BPHII scores improved by 57% at 3 months and 71% at 12 months. IIEF-15 scores improved by 15% at 6 months, and MSHQ-EjD function scores improved by 22.4% at 1 month. 3 (3.6%) men observed reduced/anejaculation. No Clavien-Dindo events ≥ Grade III occurred.

CONCLUSION

This study demonstrates for the first-time safety and efficacy of Rezum in large glands >80mL. IPSS improved by 59% and QoL improved by 70% at 12 months. Objective maximum flow measures improved at 12 months by 59%, while erectile and ejaculatory function remained preserved.

Rezūm water vapor therapy for catheter-dependent urinary retention: a real-world Canadian experience

INTRODUCTION

This analysis reported outcomes of treating catheter-dependent urinary retention with Rezūm water vapor therapy.

MATERIALS AND METHODS

A prospective registry was established at two high-volume Canadian centers. Patients had baseline medical and benign prostatic hyperplasia (BPH) history documented. The subgroup of patients with refractory, catheter-dependent urinary retention was analyzed. The primary outcome was the proportion of patients who were spontaneously voiding and catheter-free at 6 months.

RESULTS

Sixteen patients (age: 68.7 years) with catheter-dependent urinary retention were treated with Rezūm. Average prostate volume was 84.4 mL and 75% had median lobe. All patients had at least one recent failed trial without catheter (TWOC) and 87.5% were on BPH oral therapy. Mean number of vapor injections was 14.5. Visibility and bleeding during procedure were assessed using a 5-point scale, and were rated as 1.4 and 1.3, respectively. Anesthesia was either intravenous propofol sedation (n = 13) or self-administered methoxyflurane inhaler (n = 3). Mean catheter duration until first planned TWOC was 28.4 days. Three patients needed catheter replacement due to initial failed TWOC. One patient was lost to follow up, one patient did not return at 1 month, and one patient did not return at 3 months. At 1 month, 13/14 patients were spontaneously voiding and catheter-free. At 3 months, 14/14 patients were spontaneously voiding, and at 6 months, 15/15 patients were spontaneously voiding and catheter-free (1 patient was lost to follow up).

CONCLUSIONS

Rezūm water vapor therapy can successfully treat catheter-dependent urinary retention after initial failed TWOC in an outpatient setting.

GreenLight photovaporization of the prostate in high-medical-risk patients: an analysis of the Global GreenLight Group (GGG) database

PURPOSE

We sought to characterize the adjusted outcomes of GreenLight photoselective vaporization of the prostate (PVP) in high-medical-risk (HMR) patients using data from the largest international database.

METHODS

Data were obtained from the Global GreenLight Group (GGG) database which pools data of eight high-volume, experienced surgeons, from a total of seven international centers. Eligible study participants underwent GreenLight PVP using the XPS-180 W system between 2011 and 2019. HMR patients were defined as patients with ASA III or greater and were compared to non-HMR patients. Analyses were adjusted for patient age and prostate volume.

RESULTS

In the HMR group, patients on average were older and had smaller prostates than the non-HMR control group. Compared to non-HMR patients, transfusions occurred more frequently (2.6% vs. 0.14%, p < 0.01) and the odds of readmission were elevated [OR 2.0, (95% CI 1.4-2.8, p < 0.01)] among HMR patients. Twelve months postoperatively, HMR patients experience greater improvement in QoL than the control group [+ 0.54 (95% CI 0.07-1.0, p = 0.02)]. PVR also decreased 93.1 ml more in HMR than in non-HMR patients after 12 months (95% CI 33.6-152.6, p < 0.01).

CONCLUSION

We found that GreenLight PVP is safe and effective in improving functional outcomes in higher-risk patients with severe systemic disease compared to their lower-risk counterparts. Though absolute risks remain low, GreenLight PVP is associated with higher odds of transfusion and readmission in the high-risk cohort. The findings of our study reaffirm current guidelines that propose PVP as a viable treatment option for HMR patients.

Meta-analysis with individual data of functional outcomes following Aquablation for lower urinary tract symptoms due to BPH in various prostate anatomies

OBJECTIVES

To evaluate functional outcomes following Aquablation in various prostate volume and anatomical subgroups.

DESIGN

A meta-analysis with individual patient data undergoing Aquablation therapy from four prospective, global, clinical studies that have been conducted with Aquablation; WATER, WATER II, FRANCAIS WATER and OPEN WATER.

SETTING

Australia, Canada, Lebanon, Germany, New Zealand, UK and the USA.

PARTICIPANTS

425 men with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) with 1-year follow-up.

INTERVENTIONS

Aquablation therapy is an ultrasound guided, robotically executed waterjet ablative procedure for the prostate.

MAIN OUTCOME MEASURES

The analyses focus International Prostate Symptom Score (IPSS), uroflowmetry, postoperative Incontinence Severity Index (ISI) and surgical retreatment.

RESULTS

425 men with prostates ranging in size from 20 to 150 mL underwent Aquablation therapy. The outcomes from the seven questions in the IPSS questionnaire were grouped by the following; prostates <100 mL, prostates ≥100 mL, prostate anatomy with an obstructive median lobe identifed by imaging, and prostate anatomy without an obstructive median lobe. Regardless of subgroup, all outcomes are consistent and demonstrate a significant improvement from baseline. Specifically, improvements in frequency, urgency and nocturia demonstrated bladder function improvement. Patients entering treatment with severe incontinence, ISI score >4, and regardless of prostate size, showed a reduction in incontinence during patient follow-up. Surgical retreatment due to BPH symptoms occurred in 0.7% (95% CI 0.1%-2.0%).

CONCLUSIONS

Across a variety of prostate anatomies, Aquablation therapy showed remarkable functional improvements following the index procedure. Additionally, men with moderate to severe LUTS/BPH and overactive bladder resulting in urge incontinence showed a reduction in incontinence symptoms postprocedure.

Surgical treatment options for benign prostatic obstruction: beyond prostate volume

PURPOSE OF REVIEW

Many surgical treatment options are available for patients who present with benign prostatic obstruction (BPO). This article reviews the current treatment options available and distinguishes them based on five clinical considerations: antithrombotic therapy, sexual function preservation, ambulatory procedures, anesthesia-related risks and duration of catheterization.

RECENT FINDINGS

A comprehensive review of the literature was performed on 10 BPO procedures. Laser enucleation of the prostate (LEP), bipolar plasma transurethral vaporization of the prostate and photoselective vaporization (PVP) of the prostate reduces the risk of bleeding, which is recommended for anticoagulated men. Ejaculatory function is more likely to be preserved following transurethral incision of the prostate, Rezūm, Aquablation, UroLift and iTind. Same-day discharge is possible for LEP, PVP and prostatic arterial embolization (PAE). For patients with high anesthesia-related risks, procedures compatible with local anesthesia (UroLift, Rezūm, iTind and PAE) should be favored. Catheterization duration is shorter with UroLift, PVP and LEP.

SUMMARY

BPO treatment options are growing rapidly. The optimal procedure for a given patient is based on factors such as associated risks, recovery and expected outcomes. Besides prostate volume, the clinical considerations in the present article can help elucidate the best surgical BPO treatment option for each patient based on their values, preferences, and risk tolerance.

Office-Based Procedures for BPH

PURPOSE OF REVIEW

Benign prostatic hyperplasia (BPH) is a common disease in men. A rapidly rising demand for safe and effective therapy for BPH has generated novel minimally invasive surgical treatments (MISTs). With multiple procedural options in the urology armamentarium for BPH therapy, we describe the current therapies and outcomes for office-based procedures for BPH including quality of life, voiding symptoms, and sexual function.

RECENT FINDINGS

There are three FDA-approved MISTs (Rezūm, Urolift, and iTind) and three emerging MISTs for BPH. Preliminary data suggest improvement in voiding symptoms and quality of life while minimizing unwanted sexual side effects. Long term data is required on the durability and safety of MISTs for BPH. MISTs mark a paradigm shift in BPH management. Sandwiched between conservative medical management and conventional transurethral surgery, these novel technologies promise to combine efficacy approaching that of TURP while sparing the negative side effects. We envision a future where BPH can be diagnosed and treated in an office-based setting with a standard cystoscope in one procedure.

Evaluating the acceptability of an online patient decision aid for the surgical management of lower urinary tract symptoms secondary to benign prostatic hyperplasia

INTRODUCTION

The growing number of surgical options available to treat benign prostatic hyperplasia (BPH), may overwhelm patients and urologists when deciding on an optimal treatment. Therefore, we developed an online patient decision aid (PtDA) that includes all guideline-approved surgical modalities. The objective of this study was to assess the acceptability of the PtDA among former BPH surgery patients and urologists that treat BPH surgically.

METHODS

The International Patient Decision Aids Standards were used to develop a PtDA that includes monopolar transurethral resection of the prostate (TURP), bipolar TURP, GreenLight photovaporization, endoscopic enucleation of the prostate, Rezum, Urolift, Aquablation, open retropubic prostatectomy, and robotic simple prostatectomy as management options. Eleven urologists that regularly treat BPH and 19 patients who received BPH surgery were recruited. Alpha-testing was performed using a validated acceptability scoring system.

RESULTS

For all sections of the PtDA, most urologists agreed that the language used was easy to follow (91.9%), that the amount of information provided was adequate (63.6%), that the length of the PtDA was appropriate (63.6%), and that the outcomes reported were correct (81.8%). All 19 patient participants agreed that the language used was easy to follow, and most found that the amount of information provided was adequate (84.2%), that the length of the PtDA was appropriate (84.2%), and that the outcomes reported were well-explained (89.5%).

CONCLUSIONS

Our PtDA was found to be acceptable among urologists and patients. These results demonstrate that most of the participants either recommend the use of this tool or plan to incorporate it in their clinical practice.

Assessing the Accuracy, Quality, and Readability of Information Related to the Surgical Management of Benign Prostatic Hyperplasia

Objectives: To assess the accuracy, quality, and readability of online educational health information in English related to the most common benign prostatic hyperplasia (BPH) guideline-approved surgical treatments. Methods: The terms "benign prostatic hyperplasia," "BPH," and all eight guideline-approved treatment modalities studied, were searched to retrieve the first five relevant websites and first two paid advertised websites related to the surgical treatment options for BPH. These modalities included transurethral resection of the prostate (TURP), GreenLight photovaporization, endoscopic enucleation of the prostate, Rezum, Urolift, Aquablation, open simple prostatectomy, and robotic simple prostatectomy (RSP). All relevant websites were assessed for their accuracy, quality, and readability using standardized scoring systems. Results: The mean accuracy score for each of the treatment modalities were all indicative of good accuracy, with 76%-99% of the information presented as being accurate. The median quality score was statistically different across the eight treatment modalities (p = 0.015). The median readability grade level was statistically different across the eight treatment modalities (p = 0.009). Websites that described TURP (median readability grade level, 9.00 [interquartile range (IQR) 8.00-10.80]) were significantly easier to read than those related to RSP (median readability grade level, 14.35 [IQR, 11.08-16.50]) (p = 0.011). No other statistically significant differences were found within the other treatment modality websites. Conclusions: The majority of websites retrieved were found to be of high accuracy, good quality, and poor readability. Additionally, it was found that none of the retrieved websites included descriptions for all the other included treatment modalities. Given these findings, the authors recommend the development of centralized resources with all guideline-approved treatment modalities and accurate, readable, and high-quality information related to the surgical treatment of BPH.
