The pelvic-prostatic capsule is an anatomical formation, which is a dense fibro-fatty sac enclosed between the muscular walls of the pelvis and the prostate gland. This unusual capsule is present only in men and plays an important role in the mobility of the prostate and other organs of the reproductive system. Physiology The pelvic-prostatic capsule in women consists of a muscular layer that surrounds the prostate and passes into the bladder. It provides a stable and strong attachment of the gland to the supporting structures of the pelvis. In men, the pelvic capsule is located between the prostate gland and the posterior wall of the bladder. It contains fibrous tissue that helps urine flow in and out of the bladder. Violation of the pelvic-prostate capsule is observed with prostatitis, prostate adenoma, prostate tumors, congestion in the pelvis, as well as after operations on the prostate gland and bladder. If there is obstruction or compression of the gland, congestion may develop in it. This condition leads to disruption of the outflow of prostatic secretions and its stagnation in the tissues. As a result, the normal functioning of the prostate gland is disrupted, up to its complete dysfunction. More than 40% of patients with prostate adenoma have some kind of disruption of the pelvic-prostate connections. When conducting radiation studies complicated by wall porosity, and on ultrasound, chamber asymmetry is often noted
