SONOGRAPHIC ASSESSMENT OF POSTVOID RESIDUAL URINE VOLUMES
INTRODUCTION
Significant postvoid residual (PVR) urine volume is a frequent manifestation of benign prostatic hyperplasia. Assessment of this volume forms an important routine investigation, as serial measurements may indicate clinical progress. Bladder catheterization is, however, widely regarded as the gold standard of measurement. Nevertheless, it carries the risk of infection and trauma to the urethra. In addition, it has been reported to be inaccurate to some extent. Ultrasonography, as a nonin-vasive method of rapidly assessing residual urine
volume has thus been recommended as an alternative to catheter estimations by many authors.
However, while some workers advocate caution when interpreting PVR measurements by transabdominal ultrasound, others consider it sonographic evidence of dilatation of the upper renal tract and vesical diverticula. Mean age was 64.98±9.57 years (range 47-100 years). Each patient had two examinations, the first of which was with a full bladder and the second of inaccurate. Against this background, we present our experience in PVR measurements of urine in patients with benign prostatic hyperplasia. online canadian pharmacy
