Does size matter? A single institution's comparison of Aquablation in prostates greater than or less than 150 mL.

Background: Surgical management options for lower urinary tract symptoms due to benign prostatic hypertension have remained limited in prostates of large volume. The advent of the Aquablation has created a potential minimally invasive option for treatment in prostates of all volumes. Thus, this study aims to evaluate outcomes and complications of Aquablation in clinical practice based on prostate volume.

Association of Baseline Magnetic Resonance Imaging Prostate Imaging Reporting and Data System Score With Prostate Cancer Active Surveillance Early Biopsy Reclassification: Data From the Michigan Urological Surgery Improvement Collaborative (MUSIC).

Purpose: The purpose of our study was to evaluate the association of baseline MRI Prostate Imaging Reporting and Data System (PI-RADS) score with biopsy reclassification in a multicenter active surveillance (AS) cohort.

Materials And Methods: We identified men in the Michigan Urological Surgery Improvement Collaborative registry (46 hospital-based/academic/private practice urology groups) with National Comprehensive Cancer Network (NCCN) low-risk and favorable intermediate-risk prostate cancer who underwent MRI within 6 months before or after initial biopsy and enrolled in AS from June 2016 to January 2021. The primary objective was to determine the association of baseline MRI PI-RADS score (≥4 lesion) with reclassification to high-grade prostate cancer (≥grade group 3) on surveillance biopsy.

Prevalence and Causes of Discontinuation of Androgen Receptor Inhibitors in Advanced Prostate Cancer Patients and Analysis of Physician Management to Increase Duration of Therapy.

Objective: To investigate the prevalence and cause of early discontinuation (DC) of androgen receptor inhibitor (ARi) in advanced prostate cancer (PCa) patients. Additionally, to study the effect of changing ARi vs dose reduction on duration of treatment (DOT).

Materials And Methods: A retrospective cohort study of 333 patients with advanced PCa who started ARi between 2016 and 2020 was performed.

Impact of the bladder detrusor muscular ring on lower urinary tract symptoms due to benign prostatic hyperplasia: A quantitative MRI analysis.

Background: The etiology of lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH) remains uncertain.

Objective: The purpose of our study was to quantitatively analyze anatomic characteristics on magnetic resonance imaging (MRI) to assess novel independent factors for symptoms.

Methods: This retrospective single-institution study evaluated treatment-naïve men who underwent prostate MRI within 3 months of international prostate symptom score (IPSS) scoring from June 2021 to February 2022.

Which measurement method should be used for prostate volume for PI-RADS? A comparison of ellipsoid and segmentation methods.

Purpose: Prostate volume and PSA density (PSAd) are important in the risk stratification of suspected prostate cancer (Pca). PI-RADS v2.1 allows for determining volume via segmentation or ellipsoid calculation.

Benign prostate hyperplasia as a potential protective factor against prostate cancer: Insights from a magnetic resonance imaging study of compositional characteristics.

Purpose: The structural relationship between benign prostate hyperplasia (BPH) and prostate cancer (Pca) is controversial. The purpose of our study was to examine the association between quantitative prostate compositional metrics by magnetic resonance imaging (MRI) and Pca.

Methods: We identified 405 patients who underwent prostate MRI and biopsy and/or prostatectomy from January 2019 to January 2021 at our institution.

Predictors and Barriers to Faculty Scholarly Activity in United States Urology Residency Programs.

Objective: To determine factors and barriers associated with scholarly activity among faculty members at urology residency programs in the United States.

Methods: An online survey was sent to all 134 urology residency program directors. The survey assessed program characteristics including size, location and definition of scholarly activity.
