“…Benign prostatic hyperplasia (BPH) refers to an increase in the number of prostatic stromal and epithelial cells in the transition zone (TZ) and periurethral glands that cause the formation of discrete nodules and prostate enlargement. 5 It develops in response to testosterone after it is converted to dihydrotestosterone. 6 Its prevalence increases with age and affects approximately 75% of men older than 70 years.…”

Non-malignant conditions of the prostate and seminal vesicles are much more common in imaging practice than prostate cancer. They include benign prostatic hyperplasia, infective and inflammatory prostatitis, prostatic and periprostatic cysts, and benign tumors. The advances in magnetic resonance imaging (MRI) of the prostate gland have dramatically improved the ability to identify these entities, many of them being identified incidentally in patients evaluated for other indications. Good knowledge of these conditions can aid in precise diagnosis and avoid interpretation pitfalls. In this article, we present non-malignant conditions of the prostate gland using several imaging modalities, including transrectal ultrasound, MRI, and computed tomography. We also present the pathological correlation for benign tumors.

This study assesses the morphological effectiveness of benign prostatic hyperplasia (BPH) surgery using multislice spiral computed tomography three-dimensional imaging (CT3D) with urethral contrast. Twenty-five male patients with BPH and bladder outlet obstruction (BOO) who underwent bipolar transurethral resection of the prostate were selected. Preoperative and postoperative CT3D indicators of retrograde and voiding cystourethrography, including bladder neck diameter, length of the posterior urethra, and degree of prostate protrusion into the bladder and upper and lower diameter of the prostate were used to assess bladder neck and posterior urethra morphology and BOO severity. In addition, preoperative and postoperative International Prostate Symptom Scores and maximum urine flow rates were compared. Postoperative CT3D was used to evaluate changes following obstruction relief postsurgery. Preoperative CT3D indicated significant BOO, whereas postoperative imaging showed improved patency but with irregular posterior urethral lumens and varying degrees of residual glandular tissue. Comparative analysis of preoperative and postoperative bladder outlet metrics revealed significant changes ( p < 0.05). Urethral contrast CT3D effectively visualizes the prostate, bladder neck, and prostatic urethra. It quantifies changes in the urethral lumen postsurgery, correlating the extent of posterior urethral lumen spaciousness with urinary flow rates.
