Prostatic cysts are an uncommon diagnosis in men. However, in these cases, the cysts are typically asymptomatic and are discovered incidentally during examinations of the abdomen or rectum. These cysts are so rare that existing literature is mostly in the form of isolated case reports. Symptomatic cysts are more often than not associated with abscesses or chronic prostatitis, conditions between which it may be difficult to differentiate. A prostatic abscess is most often caused by an accumulation of pus within the prostate gland. These conditions tend to cause pelvic pain and be associated with urinary tract infections and are more frequent in men with diabetes or a form of immunosuppression.
There are a few medical tests that may detect the presence of a prostatic cyst or abscess. Evidence may be found in a urine test; failing this, more completed procedures may be used, such as a contrast-enhanced CT scan or an ultrasound. If a cyst or abscess is found, your doctor may want to drain it. Until fairly recently, a prostatic abscess was drained through the urethra. It has since been discovered, however, that fewer complications arise when a prostatic cyst is drained through the rectum. Your doctor will work with you to help determine the best course of treatment if it is needed.
