COMPARISON OF PROSTATE VOLUME MEASURED BY TRANSABDOMINAL ULTRASOUND AND TRANSRECTAL ULTRASOUND IN PATIENT WITH LUTS DUE TO BENIGN PROSTATIC ENLARGEMENT
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2017, Vol 4, Issue 45
Abstract
BACKGROUND A filled bladder acts as an acoustic window for transabdominal ultrasound measurements of intravesical prostatic protrusion and volume. The incidence of BPE is 18%, 29%, 40% and 56% of men in their 40s, 50s, 60s and 70s, respectively, having moderateto-severe Lower Urinary Tract Symptoms (LUTS).1 The size of the prostate are determined by Digital Rectal Examination (DRE), Transabdominal Ultrasound and Transracial Ultrasound (TRUS). DRE tends to underestimate true prostate size as determined by transabdominal ultrasound and TRUS. The magnitude of the underestimation increases with increasing prostate size from 25% up to 50% or more.2 TRUS volume measurements using the prostate ellipsoid volume formula (maximum width x height x length /6) are the most widely accepted measure of prostate volume.3 Ultrasound has been increasingly used in the evaluation of patients with Benign Prostatic Enlargement (BPE). It defines prostatic size, shape and volume, which maybe correlated with the degree of bladder outlet obstruction in BPE. Ultrasound also be used to assess the effects of BPE on the upper urinary tracts and bladder.4,5 For transabdominal ultrasound imaging of the prostate, a filled bladder is essential. It acts as an acoustic window, which readily transmits ultrasound waves and effectively serves as a conduit to the postero-caudally situated prostate. The loss of this acoustic window (an empty bladder) and over distended bladder makes ultrasound imaging and measurement of prostate difficult and unreliable.6 The aim of this study is to compare prostate volume measured by transabdominal ultrasound and by transrectal ultrasonography correlating with bladder volume.
