Prostate cysts are cystic changes occurring in the prostate gland, usually detected through ultrasonic examination of the urinary system. Most prostate cysts are small and asymptomatic, thus requiring no treatment. Larger cysts are less common and may compress the urethra, causing difficulty urinating, frequent urination, urgency, strained urination, thinning of the urine stream, and even acute urinary retention. For symptomatic prostate cysts, treatment options include ultrasound-guided transrectal or perineal prostate cyst aspiration followed by the injection of a sclerosing agent. Another surgical option is transurethral resection of the prostate cyst, which is a minimally invasive surgery.
