We present three cases of urinary tract leiomyoma — two located in the bladder and one in the ureter. Both bladder leiomyomas were treated with transurethral resection of bladder tumor (TURBT) with no evidence of recurrent disease, while the upper tract leiomyoma was managed with surveillance by patient preference, which to our knowledge, has not been previously described. The ureteral leiomyoma has remained stable at five years followup from initial diagnosis. Given the benign nature of leiomyomas and the overall low recurrence rate reported in the literature, bladder-sparing options should be emphasized when feasible, with active surveillance potentially applicable for highly select patients.

Applicant perceptions of multiple interview components were queried to identify program specific and interview modality specific strengths or weaknesses in the 2020-2021 Urology Match. METHODS A 12-question multiple choice and free text survey was emailed to 66 virtually interviewed applicants for open residency positions at a metropolitan training program after conclusion of interviews. Items of interest included interview type preference, overall interview impression, and recommendations for improvement. RESULTS A total of 50/66 (76%) applicants completed the survey corresponding to approximately 11% of the 2020 national urology...

METHODS Using the Westlaw legal database, a search was done for the keyword "priapism" between July 1, 1980 and July 1, 2020. Cases were evaluated for plaintiff demographics, reasons for filing claims, management outcomes, legal verdicts and awards and further categorized based upon the timing of the alleged malpractice. RESULTS Alleged negligence during the pre-management period was cited in 30 cases. Administration of psychotropic medications was the most common reasons for filing pre-management claims 22/56 (39.3%). Delay in care accounted for 18/56 (32.1%) and complications of surgery were 5/56 (8.9%) of claims. The majority of the completed cases were in favor of the defendants (39/47; 83.0%). There was no association between type of health care provider or timing of alleged malpractice and ultimate verdict. CONCLUSIONS Prescribing psychoactive medications without warning of the adverse effect profile is the most common reason for claims filed against providers with trazodone as the leading medication. Medical providers should ensure that patients are well informed of this adverse effect prior to prescription. Regardless, the majority of medical malpractice cases carry a verdict in favor of the defendant.

This dedicated imaging confirmed HK with a heterogeneously enhancing right upper pole 3.1 cm×3.7 cm×2.7 cm mass. Due to suspicion for aberrant vasculature on CECT, renovascular angiography was performed, which revealed recruitment of a right paravertebral vessel alongside two right renal moiety arteries and multiple right renal moiety veins. Based on vascular complexity and the surgical exposure required for arterial clamping, open transperitoneal right partial nephrectomy was preferred to minimally invasive techniques. Postoperative course was complicated by ileus, which resolved with standard management. Pathologic analysis revealed complete resection of a 5.0 cm Fuhrman grade II clear cell renal cell...

Here, we show that highly crystalline and nonagglomerated colloidal CuCo2S4 nanoparticles can be synthesized in solution at 200 °C, which is significantly lower than previously reported methods. The CuCo2S4 nanoparticles were found to be highly active electrocatalysts for the oxygen evolution reaction (OER) under strongly alkaline conditions (1.0 M KOH, pH 14), requiring an OER overpotential of 395 mV to produce a current density of 10 mA cm(-2). X-ray photoelectron spectroscopy (XPS) studies showed evidence of oxide formation, suggesting, in conjunction with the observed electrocatalytic properties, that the mixed-metal sulfides may serve as precursors to oxides and/or hydroxides, which are likely to be the catalytically ac...
