Article Synopsis
  • A study was conducted to evaluate the effectiveness of artificial urinary sphincter (AUS) placement in men who previously had a male sling procedure compared to those who had not.
  • Out of 135 patients reviewed, it was found that those with a prior sling procedure experienced shorter device survival and a higher likelihood of needing revision or replacement surgeries.
  • The findings suggest that patients with a history of sling procedures should be informed about the potential for less favorable AUS outcomes if they require further surgeries for incontinence.

Objective: To evaluate how variations in peri-operative urine culture (UCx) and antibiotic prophylaxis utilization following robot assisted laparoscopic pyeloplasty (RALP) affect post-RALP urinary tract infection (UTI) rates in children, then use data to generate a standardized care pathway.

Methods: Patients undergoing RALP at a single institution from January 2014 to October 2018 were retrospectively reviewed. Patients with vesicoureteral reflux, neurogenic bladder, intermittent catheterization, <=2 months follow-up after stent removal, or age >=18 years were excluded.

Purpose: Artificial urinary sphincters (AUS) remain the gold standard to treat male stress urinary incontinence. AUS implantation can be performed through a penoscrotal or perineal incision depending on surgeon preference.

Methods: The present study compares initial AUS implantation through two surgical approaches focusing on outcomes of continence and revision.

Introduction: Interviews are essential to the residency application process. Questions regarding marital status, childbearing, ethnicity and religion violate employment law if asked by the interviewer. In this study we determined rates of discriminatory questions asked during urology residency interviews and assessed for differences by applicant gender.

Introduction And Objective: Studies have linked Black race to prostate cancer (CaP) risk but most fail to account for established risk factors such as 5-ARI use, prostate volume, socioeconomic status, and hospital setting. We assess whether Black race remains associated with CaP and Gleason ≥3 + 4 CaP, after adjusting for clinical setting and socioeconomic and clinical factors at prostate biopsy, with a focus on men aged 40-54 years, who may be excluded from current screening guidelines.

Methods: We recruited 564 men age 40-79 undergoing initial prostate biopsy for abnormal PSA or digital rectal examination (DRE) from three publicly funded and two private hospitals from 2009-2014.

Vesicourethral anastomotic (VUA) disruption with bladder displacement into the abdominal cavity following robot-assisted laparoscopic prostatectomy (RALP) is an exceedingly rare complication. There have been no cited case reports after robotic surgery but case reports after open radical prostatectomy have been noted. Other complications related to VUA include bleeding with or without pelvic hematoma, bladder neck contracture, or severe stress urinary incontinence.

Objective: To describe an anatomically correct simulator for use in suprapubic catheter (SPC) insertion training.

Methods: A scale reproduction of an adult male pelvis with bony landmarks and a subcutaneous fluid-filled reservoir was created using platinum cured silicone rubber. This model was evaluated by 6 expert urologists for content validity with a 16-item 5-point rating scale used to evaluate domains relevant to the simulator—physical attributes, realism of experience, realism of materials, and global rating.

The role of regulatory T cells (T(regs)) in human colon cancer (CC) remains controversial: high densities of tumor-infiltrating T(regs) can correlate with better or worse clinical outcomes depending on the study. In mouse models of cancer, T(regs) have been reported to suppress inflammation and protect the host, suppress T cells and protect the tumor, or even have direct cancer-promoting attributes. These different effects may result from the presence of different T(reg) subsets.
