Manual Dexterity Predictors of Artificial Urinary Sphincter Success.

OBJECTIVE: To determine better in-office measures for artificial urinary sphincter outcomes, we investigated the ability of preoperative timed peg-transfer, pinch strength, grip strength, and Disabilities of the Arm Shoulder and Hand Outcome questionnaire in predicting postoperative satisfaction, confidence, and ease of use of artificial urinary sphincter placement for stress urinary incontinence. MATERIALS AND METHODS: A timed 9-hole peg test, pinch and grip strength assessment, and upper extremity questionnaire were administered during the preoperative visit before sphincter placement. In addition to standard preoperative workup, short-form International Consultation of Incontinence Questionnaire and physician handshake were recorded. Activation occurred 6 weeks after surgery along with assessment of adequacy of pump placement. Three months from surgery a repeat incontinence questionnaire and a survey measuring satisfaction, difficulty of use, and confidence were given. Correlation between preoperative assessment variables and the postoperative questionnaire was assessed. RESULTS: Thirty-nine patients were included. Average age and body mass index were 68.8 years and 28.8 kg/m2, respectively. Prior prostatectomy accounted for 92.3% of patients, and 46.2% had prior pelvic radiation. Postoperatively, 59.0% of patients were very satisfied; 64.1% of patients reported no difficulty of use; 53.8% felt confidence within 1 day; and 66.7% had much better bladder control. Average pad improvement count was 5.3. Pinch test was associated with satisfaction (P = .011) while peg test was associated with confidence (P = .049). Handshake and upper extremity questionnaire were not significant. CONCLUSION: The pinch and 9-hole peg transfer tests are cost-effective and easily performed adjuncts that could be used during artificial urinary sphincter evaluation for patients with unclear manual functional status.

Contemporary Trends of Systemic Neoadjuvant and Adjuvant Intravesical Chemotherapy in Patients With Upper Tract Urothelial Carcinomas Undergoing Minimally Invasive or Open Radical Nephroureterectomy: Analysis of US Claims on Perioperative Outcomes and Health Care Costs.

INTRODUCTION: New evidence indicates that minimally invasive surgery (MIS) (laparoscopic or robotic-assisted [LNU, RANU]) reaches oncologic equivalence compared with Open Radical Nephroureterectomy (ORNU) for high-risk upper-tract urothelial carcinoma (UTUC). Recently, European Association of Urology (EAU) Guidelines suggested implementing neoadjuvant chemotherapy (NAC) to standard treatment to improve oncologic outcomes of high-risk UTUC. We aimed (1) To explore contemporary trends of MIS for RNU in the United States and to compare perioperative outcomes and costs with that of ORNU. (2) To determine the trends of NAC and postoperative intravesical chemotherapy (PIC) administration for high-risk UTUC and to assess their contribution to perioperative outcomes and costs. PATIENTS AND METHODS: The Optum Clinformatics Data Mart de-identified database was queried from 2003 to 2018 to retrospectively examine patients who had undergone LNU/RANU or ORNU with or without NAC and PIC. We evaluated temporal adoption trends, complications, and health care cost analyses. We obtained descriptive statistics and utilized multivariable regression modeling to assess outcomes. RESULTS: A total of n = 492 ORNU and n = 1618 LNU/RANU procedures were reviewed. The MIS approach was associated with a statistically significant lower risk of intraoperative complications (adjusted Odds Ratio [aOR], 0.48, 95% CI:0.24-0.96), risk of hospitalization costs (aOR: 0.62, 95% CI:0.49-0.78), and shorter hospital stay (aOR: 0.20, 95% CI:0.15-0.26) when compared to ORNU. Overall, adoption of NAC and PIC accounted for only n = 81 and n < 37 cases respectively. The implementation of NAC and higher number of cycles were associated with an increased probability of any complication rate (aOR: 2.06, 95% CI:1.26-3.36) and hospital costs (aOR: 2.12, 95% CI:1.33-3.38). CONCLUSION: MIS has become the approach of choice for RNU in the US. Although recommended by guidelines, neither NAC nor postoperative bladder instillation of chemotherapy has been routinely incorporated into the clinical practice of patients with UTUC.

Removing Race from eGFR calculations: Implications for Urologic Care.

Equations estimating the glomerular filtration rate are important clinical tools in detecting and managing kidney disease. Urologists extensively use these equations in clinical decision making. For example, the estimated glomerular function rate is used when considering the type of urinary diversion following cystectomy, selecting systemic chemotherapy in managing urologic cancers, and deciding the type of cross-sectional imaging in diagnosing or staging urologic conditions. However, these equations, while widely accepted, are imprecise and adjust for race which is a social, not a biologic construct. The recent killings of unarmed Black Americans in the US have amplified the discussion of racism in healthcare and has prompted institutions to reconsider the role of race in estimation of glomerular filtration rate equations and raced-based medicine. Urologist should be aware of the consequences of removing race from these equations, potential alternatives, and how these changes may affect Black patients receiving urologic care.

Safety and Feasibility of Outpatient Surgery in Benign Prostatic Hyperplasia: a Systematic Review and Meta-Analysis.

Purpose: Most of the endourologic procedures along the urinary tract have been widely practiced as outpatient operations, including surgery for benign prostatic hyperplasia (BPH). This systematic review and meta-analysis was conducted to assess safety and feasibility of outpatient surgery for patients suffering from symptomatic BPH candidate for endoscopic disobstruction. Materials and Methods: PubMed, Web of Science, Cochrane, and Embase were searched up until March 30, 2020. Methodological index for nonrandomized studies (MINORS) tool was utilized to assess the quality of included studies, and a pooled measure of failure rate (FR) or event rate (ER) estimate was calculated. Further sensitivity analysis, subgroup analysis, and meta-regression were conducted to investigate contribution of moderators to heterogeneity. Results: Twenty studies with a total of 1626 patients treated according to outpatient criteria for endoscopic BPH surgery were included. In total, 18 studies reporting data on immediate hospital readmission and/or inability to discharge after endoscopic procedure presented FR estimates ranging from 1.7% to 51.1%. Pooled FR estimate was 7.8% (95% confidence interval [CI]: 5.2-10.3); Heterogeneity: Q = 76.85; degree of freedom = 17, p < 0.001; I2 = 75.12%. Subgroup analysis according to surgical technique revealed difference among the three approaches with pooled FR of 3% (95% CI: 1-4.9), 7.1% (95% CI: 3.9-10.4), and 11.8% (95% CI: 7-16.7) for transurethral resection of the prostate, Green-light, and holmium laser vaporesection, respectively (p < 0.001). At meta-regression analysis, none of the retrieved covariates was able to significantly influence the cumulative outcomes reported. ER for postoperative complications and early outpatient visit showed a pooled estimate of 18.6% (95% CI: 13.2-23.9) and 7.7% (95% CI: 4.3-11), respectively. Conclusions: Our analysis revealed how transurethral procedures for BPH on an outpatient setting are overall reliable and safe. Of note, there were significant outcome differences between groups with regard to type of surgical procedure, perioperative prostate volume, and discharge protocol suggesting the need for further prospective analysis to better elucidate the best strategy in such outpatient conduct.

Resolution of bilateral testicular masses after viral infection.

We present a case of viral-associated orchitis with bilateral testicular masses initially concerning for malignancy on scrotal ultrasound. In this case, patient underwent observation after discussing management options. Literature search revealed two cases of benign testicular mass after viral infection that was managed with radical orchiectomy. The previously documented case allowed for appropriate counseling to delay surgical intervention and allow for spontaneous resolution of the viral-induced testicular masses.

Sudden PSA rise to ≥20 ng/ml and prostate cancer diagnosis in the United States: A population-based study.

PURPOSE: While prostate-specific antigen (PSA) screening protocols vary, many clinicians have anecdotes of screened men with low PSA levels that rise significantly and are associated with high-risk prostate cancer (PC). We sought to better understand the frequency of high-risk cases that appear suddenly in a screened population. METHODS: We utilized data from a Commercial and Medicare advantage claims database to identify all US men ages 50 and above undergoing PSA screening who then had a sudden interval rise in PSA (e.g., PSA ≥ 20) and diagnosis of PC. We determined associations with age, race, screening intensity, and baseline PSA levels. RESULTS: In all, 526,120 men met entry criteria with an average age of 60.7 and follow-up of 5.6 years. As the baseline PSA increased, the rate of high-risk PC increased from 2/10,000 persons among men with the lowest baseline PSA (<1 ng/ml) to 14/10,000 person-years among men with a baseline PSA < 5 ng/ml. Moreover, as a man's age at baseline PSA increased, the rate of high-risk PC also increased. In contrast, the incidence of high-risk PC did not vary significantly by race/ethnicity. More screening PSAs and shorter intervals between PSA screenings were associated with a lower incidence of high-risk PC. CONCLUSIONS: The incidence of high-risk PC in a screened population is low (<0.1%). Our findings suggest that systematic screening cannot eliminate all PC deaths and provide an estimate for the risk of the rapid development of high-risk cancers that is comparable to that observed in active surveillance populations.

Optic nerve inflammation and demyelination in a rodent model of nonarteritic anterior ischemic optic neuropathy.

PURPOSE: Optic nerve (ON) ischemia associated with nonarteric anterior ischemic optic neuropathy (NAION) results in axon and myelin damage. Myelin damage activates the intraneural Ras homolog A (RhoA), contributing to axonal regeneration failure. We hypothesized that increasing extrinsic macrophage activity after ON infarct would scavenge degenerate myelin and improve postischemic ON recovery. We used the cytokine granulocyte-macrophage colony-stimulating factor (GM-CSF) to upregulate ON macrophage activity, and evaluated GM-CSF's effects after ON ischemia in the NAION rodent model (rAION). METHODS: Following rAION induction, GM-CSF was administered via intraventricular injection. Retinal ganglion cell (RGC) stereologic analysis was performed 1 month postinduction. The retinae and optic nerve laminae of vehicle- and GM-CSF-treated animals were examined immunohistochemically and ultrastructurally using transmission electron microscopy (TEM). RhoA activity was analyzed using a rhotekin affinity immunoanalysis and densitometry. Isolated ONs were analyzed functionally ex vivo by compound action potential (CAP) analysis. RESULTS: Rodent NAION produces ON postinfarct demyelination and myelin damage, functionally demonstrable by CAP analysis and ultrastructurally by TEM. Granulocyte-macrophage colony-stimulating factor increased intraneural inflammation, activating and recruiting endogenous microglia, with only a moderate amount of exogenous macrophage recruitment. Treatment with GM-CSF reduced postinfarct intraneural RhoA activity, but did not neuroprotect RGCs after rAION. CONCLUSIONS: Sudden ON ischemia results in previously unrecognized axonal demyelination, which may have a clinically important role in NAION-related functional defects and recovery. Granulocyte-macrophage colony-stimulating factor is not neuroprotective when administered directly to the optic nerve following ON ischemia, and does not improve axonal regeneration. It dramatically increases ON-microglial activation and recruitment.
