The prostatic utricle (Latin for "small pouch of the prostate") is a small indentation in the prostatic urethra, at the apex of the urethral crest, on the seminal colliculus (verumontanum), laterally flanked by openings of the ejaculatory ducts.
Abdominal ultrasound examination of the prostate and kidneys is often performed to rule out hydronephrosis and hydroureter. Incidentally, cysts, tumours, and stones may be found on ultrasound. Post-void residual volume of more than 100 ml may indicate significant obstruction. [52] Prostate size of 30 cc or more indicates enlargement of the ...
Transrectal ultrasonography, or TRUS in short, is a method of creating an image of organs in the pelvis, most commonly used to perform an ultrasound-guided needle biopsy evaluation of the prostate gland in men with elevated prostate-specific antigen or prostatic nodules on digital rectal exam.
Prostatic calculi (PC), prostatic stones, prostatic calcification or prostatic lithiasis, are hyper-echoic mineral deposits in the prostate that are frequently detected incidentally during transabdominal ultrasonography, transrectal ultrasonography, or computed tomography.
The prostate gland enlarges and compresses the adjacent urethra, making it difficult for men to control frequency and/or urgency of urination. [21] First-line therapy involves medication, though long-term treatment for symptoms that are persistent despite medical optimization typically involves transurethral resection of the prostate (TURP) as ...
The prostate is an accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation.

A similar paper in European Radiology found that when correlated with histopathology, PI-RADS v2 correctly identified 94-95% of prostate cancer foci ≥0.5 mL, but was limited for the assessment of GS ≥4+3 (significant) tumors ≤0.5 mL; in their series, DCE-MRI offered limited added value to T2WI+DW-MRI.
