Abstract

PURPOSE OF REVIEW:

This article discusses the new imaging techniques in diagnosis and treatment of benign prostatic hyperplasia by reviewing the most recent publications.

RECENT FINDINGS:

Imaging study for the evaluation of patients with lower urinary tract symptoms is not suggested by American Urology Association guidelines; however, European Association of Urology recommends the assessment of the upper urinary tract by modalities like ultrasound. Several new imaging indices like resistive index of capsular artery, presumed circle area ratio, prostatic urethral angle, intraprostatic protrusion, and detrusor wall thickness are used to find a noninvasive way for bladder outlet obstruction diagnosis. In addition to them, 3D transrectal ultrasound, near infrared spectroscopy, and MRI are used to add more practical findings in patient management.

SUMMARY:

Urologists have requested more imaging studies than expected for benign prostatic hyperplasia patients in recent years, and several studies have been done to find a noninvasive way to diagnose bladder outlet obstruction. However, none of them could play the urodynamic studies role in bladder outlet obstruction diagnosis.
