Point-of-care ultrasound: Usage and accuracy within a Canadian urology division

Abstract

Introduction: This research evaluates point-of-care ultrasound's (POCUS) utility and precision in urology, inspired by recent affirmations of its feasibility and value.1,2 Our study provides valuable insights for urologists about POCUS's practical usage. Methods: A prospective study assessed POCUS usage and accuracy in the Division of Urology using data from April 4, 2022, to April 4, 2023. Data include POCUS indications, findings, and correlation with the final diagnosis/gold standard. Additionally, a qualitative survey was conducted among urologists and residents about POCUS's pros, cons, and barriers to integration. Results: Thirty-three patients underwent POCUS examinations, mainly for suspected hydronephrosis (27%, n=9). Other indications included urinary retention, testicular mass, torsion, cryptorchidism, renal mass, eFAST exams, nephrostomy tube placement confirmation, and scrotal hematomas. POCUS findings matched the final diagnosis in most cases, showing 86% sensitivity, with an average exam time of 1–5 minutes. POCUS showed potential for suprapubic tube insertions. Residents (60%, n=20) were the most frequent users, followed by staff (33%, n=10), and students (6%, n=2). The surveyed urologists and residents expressed comfort with POCUS but cited time, cost, and practicality as barriers. Conclusions: POCUS proves accurate and beneficial in urology, particularly for hydronephrosis. Most findings align with the gold standard, and the average exam time is brief. Barriers include time and cost. Further research is necessary to evaluate cost-effectiveness and POCUS's impact on patient outcomes in routine urologic practice.
