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.

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.

Partial gland ablation with high intensity focal ultrasound impact on genito-urinary function and quality of life: our initial experience

INTRODUCTION

  Partial gland ablation (PGA) using high intensity focal ultrasound (HIFU) is an alternative to active surveillance for low to intermediate risk localized prostate cancer.  This pilot study assessed quality of life (QoL) outcomes during the implementation of PGA-HIFU at our institution.

MATERIALS AND METHODS

  We prospectively enrolled 25 men with a diagnosis of localized low/intermediate risk prostate cancer who elected to undergo PGA-HIFU in a pilot study at our institution between 2013 and 2016.  Patients underwent pre-treatment mpMRI and transrectal ultrasound-guided biopsies.  The primary endpoints were impact on patient-reported functional outcomes (erectile, urinary function, QoL) assessed at 1, 3, 6- and 12-months.

RESULTS

  The median age was 64 years old (IQR 59.5-67).  Baseline median International Index of Erectile Function-15 score was 50, which decreased to 18 at 1 month (p < 0.0005), returned to baseline by 3 months and thereafter. International Prostate Symptom Score median at baseline was 8, which worsened to 12 at 1 month (p = 0.0088), and subsequently improved to baseline thereafter.  On the UCLA-Expanded Prostate Cancer Index Composite urinary function, there was a decrease in median score from 92.7 at baseline to 76.0 at 1 month (p < 0.0001), which improved to or above baseline afterwards.  QoL remained similar to baseline at each follow up period as assessed by EQ-5D and the Functional Cancer Therapy-Prostate score.

CONCLUSIONS

  In this initial cohort of PGA-HIFU men at our institution, patients demonstrated a slight, but transient, deterioration in urinary and erectile function at 1 month prior to normalization.  All QoL metrics showed no impact upon 1 year of follow up post-treatment.

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.

Evaluating the perceptions of Canadian urology residents and program directors regarding the current training in genitourinary imaging

INTRODUCTION

Competency in interpreting genitourinary (GU) imaging is an important skill for urologists; however, no nationally accredited GU imaging curriculum exists for Canadian urology residency training programs. The main objectives of our study were to 1) characterize GU imaging training in Canada; (2) evaluate residents' self-perceived competencies in interpreting GU imaging; (3) explore program directors' (PD) and residents' perceptions regarding the current imaging curriculum and suggestions for future directions.

METHODS

From November to December 2022, a survey examining current imaging education in residency, perceived resident imaging knowledge, avenues for improvement in imaging education, and the role of point-of-care ultrasound within urology was distributed to all Canadian urology PDs and residents.

RESULTS

All PDs (13/13) and 40% (72/178) of residents completed the survey. Only two programs had a formal GU imaging curriculum. PDs and residents reported trainees were least comfortable interpreting Doppler ultrasound of renal, gonadal, and penile vessels. PDs reported that residents were most comfortable with non-contrast computed tomography (CT) scans (9.5/10), CT urogram (9.3/10), and retrograde pyelography (9.3/10). All but one PD favored increasing imaging training in their program. PDs highlighted the lack of time in the curriculum (n=3) and lack of educators (n=3) as the primary barriers to increasing imaging training in their program.

CONCLUSIONS

Most PDs and residents believe there needs to be more imaging training offered at their institution; however, addressing this is challenging due to the limited time in the curriculum and the need for available educators.

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.

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.

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.

What is the prevalence of hepatic steatosis on ultrasonography in patients followed for nephrolithiasis?

INTRODUCTION

Patients with non-alcoholic fatty liver disease (NAFLD) have higher prevalence of nephrolithiasis. The aim of the present study was to determine prevalence of hepatic steatosis on ultrasonography in nephrolithiasis patients.

METHODS

Charts of 318 consecutive nephrolithiasis patients seen in stone clinic between January and February 2018 were retrospectively reviewed. Ultrasound reports were reviewed for hepatic steatosis. Subsequent liver investigations were noted. Patients' demographic predictors of hepatic steatosis were identified using univariable logistic regression models.

RESULTS

A total of 162 patients was included, of which 76 (46.9%) were found to have hepatic steatosis and 22 (13.6%) were found to have moderate-to-severe hepatic steatosis. Median followup was 2.03 years. Predictors of hepatic steatosis included higher body mass index and smoking (both p<0.05). Progression of fatty liver on ultrasound was noted for 13 (17.1%) and regression was noted for two (2.6%). Of the 16 patients with a Fibrosis-4 (FIB-4) score, four (25.0%) patients required further investigation and 12 (75.0%) were unlikely to have advanced fibrosis. Of 12 patients who underwent fibroscan, one (8.3%) had both fibrosis and cirrhosis, two (16.7%) fibrosis only, and two (16.7%) moderate-to-severe steatosis.

CONCLUSIONS

Hepatic steatosis on ultrasound followup of nephrolithiasis patients is common, especially in smokers and overweight patients. Current recommendations suggest that primary care physicians calculate a FIB-4 score upon the detection of hepatic steatosis on ultrasound. The decision to refer to hepatology for a corroborative fibroscan is then based on the FIB-4 score.

Clinical Applications of Machine Learning for Urolithiasis and Benign Prostatic Hyperplasia: A Systematic Review

INTRODUCTION

Previous systematic reviews related to machine learning (ML) in urology often overlooked the literature related to endourology. Therefore, we aim to conduct a more focused systematic review examining the use of ML algorithms for benign prostatic hyperplasia (BPH) or urolithiasis. In addition, we are the first group to evaluate these articles using the STREAM-URO framework.

METHODS

Searches of MEDLINE, Embase, and the Cochrane CENTRAL databases were conducted from inception through July 12, 2021. Keywords included those related to ML, endourology, urolithiasis, and BPH. Two reviewers screened the citations that were eligible for title, abstract and full-text screening, with conflicts resolved by a third reviewer. Two reviewers extracted information from the studies, with discrepancies resolved by a third reviewer. The data collected was then qualitatively synthesized by consensus. Two reviewers evaluated each article according to the STREAM-URO checklist with discrepancies resolved by a third reviewer.

RESULTS

After identifying 459 unique citations, 63 articles were retained for data extraction. Most articles consisted of tabular (n=32) and computer vision (n=23) tasks. The two most common problem types were classification (n=40) and regression (n=12). In general, most studies utilized neural networks as their ML algorithm (n=36). Among the 63 studies retrieved, 58 were related to urolithiasis and five focused on BPH. The urolithiasis studies were designed for outcome prediction (n=20), stone classification (n=18), diagnostics (n=17), and therapeutics (n=3). The BPH studies were designed for outcome prediction (n=2), diagnostics (n=2), and therapeutics (n=1). On average, the urolithiasis and BPH articles met 13.8 (SD 2.6), and 13.4 (4.1) of the 26 STREAM-URO framework criteria, respectively.

CONCLUSIONS

The majority of the retrieved studies successfully helped with outcome prediction, diagnostics, and therapeutics for both urolithiasis and BPH. While ML shows great promise in improving patient care, it is important to adhere to the recently developed STREAM-URO framework to ensure the development of high-quality ML studies.

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.

An Approach to the Management of Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH) is a condition that affects up to 50% of men over the age of 50; the condition’s  prevalence  increases with age, particularly after the age of 40. BPH can lead to lower urinary tract symptoms (LUTS) which can have a significant negative impact on health-related quality of life (HRQoL). Men presenting with a gradual onset of LUTS are often suspected to have BPH. However, the clinician must recognize that LUTS possess many different aetiologies. This article aims to provide medical students with a stepwise approach to the diagnosis and management of LUTS that are secondary to BPH. The outlined approach describes the differential diagnoses, required investigations, and management-related details for LUTS that are secondary to BPH. This approach is based off of relevant Canadian, American, and European urological association guidelines.

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.

Pilot trial of telemedicine in urology: Video vs. telephone consultations

INTRODUCTION

In the past year, due to the COVID-19 pandemic, in-person clinical activities have been drastically restricted, driving the already growing interest in the use of telemedicine in the urban setting to reduce unnecessary commute. Therefore, there has been a rapid shift to telephone and video consultations in outpatient practice. We sought to conduct a pilot trial to establish feasibility and acceptability of video consultations as an alternative to telephone consultations in urology patients to inform the design of a future randomized controlled trial.

METHODS

We conducted a single-center, prospective, non-randomized pilot trial comparing telephone consultations (TC) vs. video consultations (VC) for urology outpatient visits. Two patient questionnaires were used to collect demographic information, as well as data about acceptability, feasibility, satisfaction, cost, and issues with telemedicine. Questions were identical for both VC and TC except for certain questions inquiring about issues specific to each technology.

RESULTS

Forty-eight TC patients and 66 VC urology patients were included in this study. Patients believed that telemedicine visits did not significantly hinder their ability to communicate with their urologists and that these visits would be associated with cost savings. There was 1/48 (2.1%) failed TC and 16/66 (24.2%) failed VC. VC failures were concentrated at the beginning of the trial prior to giving feedback to the VC platform creators, with only one failure occurring thereafter. When comparing TC to VC, differences between the two patient groups were small but tended to be in favor of VC. Patients' satisfaction was greater with VC compared to TC. Both modalities were associated with many cost benefits for patients.

CONCLUSIONS

Despite more technical issues with VC, this modality is feasible and acceptable to patients, likely due to improved shared decision-making with VC. Future considerations for trials comparing VC and TC should include adequate Wi-Fi infrastructure and choice of platform. For the VC, continuous knowledge transfer between investigators and platform engineers plays an important role in limiting failed encounters.

Is a contralateral testicular exploration required at microdissection testicular sperm extraction for men with nonobstructive azoospermia, cryptozoospermia or severe oligozoospermia?

OBJECTIVES

Men with nonobstructive azoospermia (NOA), cryptozoospermia and severe oligozoospermia are candidates for microdissection testicular sperm extraction (micro-TESE) and intracytoplasmic sperm injection (ICSI). We sought to evaluate micro-TESE outcomes and the need for bilateral testicular exploration in the three groups of men.

METHODS

We conducted a retrospective study of 233 consecutive micro-TESEs in men with nonobstructive azoospermia (n = 173), cryptozoospermia (n = 43) and severe oligozoospermia (n = 17). The decision to terminate the micro-TESE after a unilateral or bilateral testicular exploration was determined at the time of surgery and was based on the presence or absence of mature spermatozoa in the harvested micro-biopsies. Final assessment of sperm recovery, on the day of ICSI, was reported as successful (available spermatozoon for ICSI) or unsuccessful (no spermatozoon for ICSI).

RESULTS

Unilateral testicular exploration resulted in successful sperm retrieval in 43% (75/173), 79% (34/43) and 100% (17/17) of men with NOA, cryptozoospermia and severe oligozoospermia respectively. Therefore, 57%, 21% and none of the men with NOA, cryptozoospermia and severe oligozoospermia, respectively, required a bilateral micro-TESE. Overall, micro-TESE resulted in successful sperm retrieval in 52% (90/173), 91% (39/43) and 100% (17/17) of men with NOA, cryptozoospermia and severe oligozoospermia respectively.

CONCLUSION

Our data indicate that men with severe oligozoospermia are unlikely to require a bilateral testicular exploration at micro-TESE. Moreover, most cryptozoospermic men will have a successful sperm retrieval by micro-TESE with the majority of these patients requiring a unilateral exploration. In contrast, over 50% of the men with nonobstructive azoospermia will require a bilateral micro-TESE.

Global Greenlight Group: largest international Greenlight experience for benign prostatic hyperplasia to assess efficacy and safety

INTRODUCTION

Greenlight photo-selective vaporization of the prostate (GL-PVP) has gained international acceptance as a safe and effective alternative procedure for the treatment of benign prostatic hyperplasia (BPH), especially in anticoagulated men. This descriptive analysis aims to characterize the current state of GL-PVP, pooling data from international centers.

METHODS

Data from 3627 patients who underwent GL-PVP with the XPS-180 W system in seven international centers performed by eight expert surgeons between 2011 and 2019 were retrospectively analyzed. Demographic, perioperative, and postoperative data were collected, including IPSS, QoL, Qmax, PVR, and PSA, and complications.

RESULTS

At baseline, median age, prostate volume, PSA, and IPSS were 70 years (interquartile range 64-77), 64 (47-90), 3.1 ng/mL (1.8-6), and 22 (19-27), respectively. Median lasing and operative time were 34 (23-48) and 62 min (46-85), respectively. Median energy use was 250.0 kJ (168.4-367.9), with 92.6% of procedures being completed with one laser fiber. In 60.1% of cases, catheter was removed on postoperative day 1 with median length of 2 days. All-cause mortality within 30 days was 0.3%. Median PSA reduction at 3 months and 60 months compared to baseline was 43.9 and 46.4%, respectively (p < 0.001). All functional outcomes (IPSS, QoL, Qmax, and PVR) were significantly improved across study period when compared to baseline (p < 0.001). For those men with longer follow-up available, the observed surgical BPH retreatment rate was 1.5% CONCLUSION: Using the largest multi-user, international database of GL-PVP, Greenlight XPS laser treatment in experienced hands is a safe, effective, and durable BPH treatment option.
