Interaction between race and prostate cancer treatment benefit in the Veterans Health Administration.

BACKGROUND: Studies have demonstrated that Black men may undergo definitive prostate cancer (CaP) treatment less often than men of other races, but it is unclear whether they are avoiding overtreatment of low-risk disease or experiencing a reduction in appropriate care. The authors' aim was to assess the role of race as it relates to treatment benefit in access to CaP treatment in a single-payer population. METHODS: The authors used the Veterans Health Administration (VHA) Corporate Data Warehouse to perform a retrospective cohort study of veterans diagnosed with low- or intermediate-risk CaP between 2011 and 2017. RESULTS: The authors identified 35,427 men with incident low- or intermediate-risk CaP. When they controlled for covariates, Black men had 1.05 times the odds of receiving treatment in comparison with non-Black men (P < .001), and high-treatment-benefit men had 1.4 times the odds of receiving treatment in comparison with those in the low-treatment-benefit group (P < .001). The interaction of race and treatment benefit was significant, with Black men in the high-treatment-benefit category less likely to receive treatment than non-Black men in the same treatment category (odds ratio, 0.89; P < .001). CONCLUSIONS: Although race does appear to influence the receipt of definitive treatment in the VHA, this relationship varies in the context of the patient's treatment benefit, with Black men receiving less definitive treatment in high-benefit situations. The influence of patient race at high treatment benefit levels invites further investigation into the driving forces behind this persistent disparity in this consequential group.

The Role of Health Insurance in Patient Reported Satisfaction with Bladder Management in Neurogenic Lower Urinary Tract Dysfunction Due to Spinal Cord Injury.

PURPOSE: Neurogenic lower urinary tract dysfunction is a significant source of morbidity for individuals with spinal cord injury and is managed with a range of treatment options that differ in efficacy, tolerability and cost. The effect of insurance coverage on bladder management, symptoms and quality of life is not known. We hypothesized that private insurance is associated with fewer bladder symptoms and better quality of life. MATERIALS AND METHODS: This is a cross-sectional, retrospective analysis of 1,226 surveys collected as part of the prospective Neurogenic Bladder Research Group SCI Registry. We included patients with complete insurance information, which was classified as private or public insurance. The relationship between insurance and bladder management, bladder symptoms and quality of life was modeled using multinomial logistic regression analysis. Spinal cord injury quality of life was measured by the Neurogenic Bladder Symptom Score. RESULTS: We identified 654 privately insured and 572 publicly insured individuals. The demographics of these groups differed by race, education, prevalence of chronic pain and bladder management. Publicly insured patients were more likely to be treated with indwelling catheters or spontaneous voiding and less likely to take bladder medication compared to those with private insurance. On multivariate analysis insurance type was not associated with differences in bladder symptoms (total Neurogenic Bladder Symptom Score) or in urinary quality of life. CONCLUSIONS: There is an association between insurance coverage and the type of bladder management used following spinal cord injury, as publicly insured patients are more likely to be treated with indwelling catheters. However, insurance status, controlling for bladder management, did not impact bladder symptoms or quality of life.

The Role of Urodynamics in the Pre-transplant Evaluation of Renal Transplant.

PURPOSE OF REVIEW: The goal of this study is to delineate the role of advanced urologic evaluation with urodynamics prior to renal transplantation. We seek to report on its indications, possible findings, and subsequent treatment pathways. RECENT FINDINGS: This body of literature is largely comprised of retrospective, single-site studies. Patient selection for urodynamics can be determined based on patient history and voiding symptoms. Many of these renal transplant patients have urodynamic abnormalities such as decreased bladder capacity and compliance. Appropriate treatment of these abnormalities allows for average rates of graft survival. Urodynamic evaluation is not needed in every renal transplant recipient. However, in patients with oliguria or bladder dysfunction, urodynamics can often reveal significant pathology. The well-selected patient with lower urinary tract symptoms may also benefit from urodynamic evaluation. Treatment options are widely variable, from observation to reconstructive surgery, and should be based on the patient and urodynamic findings.

Transvaginal Paravaginal Native Tissue Anterior Repair Technique: Initial Outcomes.

OBJECTIVE: To present the surgical technique and initial outcomes for a novel lattice-work technique, developed to increase the durability of the native tissue repair. METHODS/ MATERIALS: All patients undergoing transvaginal anterior prolapse repair with a single surgeon with at least 30 days of follow-up were prospectively enrolled starting in 2017. All patients received the same repair (Fig. 1). 2.0 polydioxanone (PDS) sutures are placed at the level of the obturator fascia/arcus tendineus distally and proximally on each side. The midline anterior colporrhaphy is performed with 4 2.0 PDS sutures which are then intertwined with the obturator sutures and tied to form a lattice of sutures to reinforce the cystocele repair and elevate the central defect repair laterally. Clinic notes, objective physical exam, and standardized subjective patient questionnaires (Pelvic Floor Disorders Inventory) were evaluated for patient outcomes. Recurrence was defined anatomically (Pelvic organ prolapse-Q Ba ≥-1) and subjectively (bothersome vaginal bulge). RESULTS: There were 109 patients enrolled with a mean follow-up time was 12 months. Over the follow-up period, there were 12 anatomic recurrences (11%). This was not associated with concomitant apical or posterior repair. Mean time to recurrence was 13.9 months. There were no intraoperative complications. Transient urinary retention was the most notable complication (19%, managed conservatively). Rate of de novo stress urinary incontinence was low at 4%. CONCLUSION: This novel lattice-work technique is simple to perform and has excellent short term anatomic outcomes. Transient postoperative retention was observed; however, all cases self-resolved. Further follow-up is ongoing to characterize the long-term durability of this repair.

The Association of Veterans' PSA Screening Rates With Changes in USPSTF Recommendations.

BACKGROUND: In 2012, the United States Preventative Services Task Force (USPSTF) formally recommended against all prostate-specific antigen (PSA) screening for prostate cancer. Our goal was to characterize PSA screening trends in the Veterans Health Administration (VA) before and after the USPSTF recommendation and to determine if PSA screening was more likely to be ordered based on a veteran's race or age. METHODS: Using the VA Corporate Data Warehouse, we created 10 annual groups of PSA-eligible men covering 2009-2018. We identified all PSA tests performed in the VA to determine yearly rates of PSA screening. All statistical tests were 2-sided. RESULTS: The overall rate of PSA testing in the VA decreased from 63.3% in 2009 to 51.2% in 2018 (P < .001). PSA screening rates varied markedly by age group during our study period, with men aged 70-80 years having the highest initial rate and greatest decline (70.6% in 2009 to 48.4% in 2018, P < .001). Men aged 55-69 years had a smaller decline (65.2% in 2009 to 58.9% in 2018, P < .001) whereas the youngest men, aged 40-54 years, had an increase in PSA screening (26.2% in 2009 to 37.8% in 2018, P < .001). CONCLUSIONS: In this analysis of PSA screening rates among veterans before and after the 2012 USPSTF recommendation against screening, we found that overall PSA screening decreased only modestly, continuing for more than one-half of the men in our study. Veterans of different races had similar screening rates, suggesting that VA care may minimize racial disparities. Veterans of varying ages experienced statistically significantly differences in PSA screening trends.

Mirabegron Versus Solifenacin in Multiple Sclerosis Patients With Overactive Bladder Symptoms: A Prospective Comparative Nonrandomized Study.

OBJECTIVE: To determine the patient-perceived effectiveness and tolerability of mirabegron compared to solifenacin in a multiple sclerosis (MS) population with overactive bladder (OAB) symptoms. MATERIALS AND METHODS: MS patients with OAB symptoms who were not on medication for their urinary symptoms at enrollment were prospectively recruited. Patients enrolled in years 1-2 were prescribed mirabegron, whereas patients enrolled in years 3-4 were prescribed solifenacin. At enrollment and 6-week follow-up, patients completed several patient reported outcome measures. The primary outcome was change in OAB Questionnaire Short Form (OAB-q SF) symptom severity and minimal clinically important difference (MCID) achievement. The Patient Assessment of Constipation Symptoms (PAC-SYM) was used to assess bowel function over the treatment period. RESULTS: Sixty-one patients were enrolled. The majority of the mirabegron (70%) and the solifenacin (69%) group achieved the OAB-q SF symptom severity MCID. The solifenacin group had a statistically significant greater decrease in its end of study OAB-q SF score (Δ = -37.87 vs -20.43, P = .02). Constipation improved in the mirabegron group and worsened in the solifenacin group (ΔPAC-SYM = -0.38 vs +0.22; P = .02), with 30% of patients prescribed solifenacin experiencing worsening above the MCID threshold. CONCLUSION: Among MS patients, we demonstrated similar response rates to mirabegron and solifenacin, with approximately 50%-70% achieving each patient reported outcome measure's MCID. Though this small study showed some short-term evidence that improvement in urinary symptom severity was greater with solifenacin, this potential benefit must be weighed against the observed risk of worsening constipation. Further studies are needed to confirm these findings.

Burden of Disease for Urethral Stricture Managed by Repeat Endoscopic Treatment vs Single Endoscopic Treatment or Urethroplasty in the Veterans Affairs Population.

INTRODUCTION: Male urethral stricture disease is a challenging urological condition that affects nearly a third of men 65 years old or older. Management options include dilation and urethrotomy as well as urethroplasty, an open approach with increased morbidity and durability. Presently optimal management remains debated. In this study we focus on emergent procedures required by male patients in the Veterans Health Administration after stricture treatment as an indicator of clinically significant complications, comparing treatment approaches. METHODS: We performed an institutional review board approved, retrospective, cohort study of male veterans with urethral stricture from 2005 to 2014. Our independent variable was immediate or delayed urethroplasty or continued endoscopic treatments. Our dependent variable was a stricture related procedure performed in the emergent or urgent care setting. We used a binary logistic regression model to model the likelihood of an adverse outcome as predicted by treatment type. RESULTS: In our cohort of 9,632 patients 1.8% underwent immediate urethroplasty and 3% underwent delayed urethroplasty. Of the operated men 5.3% had an adverse outcome (5% following delayed urethroplasty or continued endoscopic treatments and 1% after immediate urethroplasty, p = 0.04). On multivariate analysis repeat endoscopy and delayed urethroplasty trended toward worsening odds of adverse outcomes (p = 0.07 and p = 0.08, respectively). CONCLUSIONS: In the Veterans Health Administration system men who undergo repeated scheduled endoscopic treatments for urethral stricture may be at increased risk for emergent procedures, even if they eventually progress to urethroplasty, compared to men who undergo urethroplasty immediately after a failed endoscopic intervention.

3D printed renal cancer models derived from MRI data: application in pre-surgical planning.

OBJECTIVE: To determine whether patient-specific 3D printed renal tumor models change pre-operative planning decisions made by urological surgeons in preparation for complex renal mass surgical procedures. MATERIALS AND METHODS: From our ongoing IRB approved study on renal neoplasms, ten renal mass cases were retrospectively selected based on Nephrometry Score greater than 5 (range 6-10). A 3D post-contrast fat-suppressed gradient-echo T1-weighted sequence was used to generate 3D printed models. The cases were evaluated by three experienced urologic oncology surgeons in a randomized fashion using (1) imaging data on PACS alone and (2) 3D printed model in addition to the imaging data. A questionnaire regarding surgical approach and planning was administered. The presumed pre-operative approaches with and without the model were compared. Any change between the presumed approaches and the actual surgical intervention was recorded. RESULTS: There was a change in planned approach with the 3D printed model for all ten cases with the largest impact seen regarding decisions on transperitoneal or retroperitoneal approach and clamping, with changes seen in 30%-50% of cases. Mean parenchymal volume loss for the operated kidney was 21.4%. Volume losses >20% were associated with increased ischemia times and surgeons tended to report a different approach with the use of the 3D model compared to that with imaging alone in these cases. The 3D printed models helped increase confidence regarding the chosen operative procedure in all cases. CONCLUSIONS: Pre-operative physical 3D models created from MRI data may influence surgical planning for complex kidney cancer.
