Antibiotic resistance in patients undergoing serial prostate biopsies: risk factors and impact on clinical outcomes.

Introduction: We evaluate the rate of developing ciprofloxacin resistance in patients undergoing repeat prostate biopsies (PBx), associated risk factors, and impact on complications.

Materials And Methods: We retrospectively evaluated pre-procedural rectal culture (RCx) data in men undergoing PBx from 1/1/2016 to 1/15/2021. Univariate and multivariate logistic regression were utilized to identify risk factors associated with development of antibiotic resistance.

Incidence of Benign Renal Masses in a Contemporary Cohort of Patients Receiving Partial Nephrectomy for Presumed Renal Cell Carcinoma.

Introduction: Over the past decade and a half, advances in diagnostic imaging as well as an increased utilization of active surveillance (AS) and renal mass biopsy (RMB) have led to an improved ability to identify benign lesions prior to partial nephrectomy (PN). We seek to examine the incidence of benign pathology at the time of PN in a contemporary cohort of patients undergoing PN for presumed renal cell carcinoma (RCC).

Patients And Methods: We performed a chart review on a prospectively maintained database on a series of patients who underwent PN between January 1, 2006 and December 31, 2021 for solid renal masses concerning for RCC.
