Prostate cyst is formed by the obstruction of the duct or duct of the prostate and the accumulation of secretion of the prostate. The severity of clinical symptoms is related to the size of the cyst. With the increase of cyst fluid, the local or whole gland of the prostate is enlarged, which compresses the nearby rectum and urethra, resulting in defecation and urination disorders, but it is not much difficult to put the catheter into the bladder. Rectal palpation can feel wave motion, no pain, and asymmetric prostatic enlargement. Abdominal palpation can touch a large lump. Similar to hard tissue block. After B-ultrasound or X-ray examination, localized cystic fluid density can be seen in the abdomen.
There are two types of prostate cysts: congenital and acquired
Prostate cyst is a cystic change of the prostate gland due to congenital or acquired reasons. Congenital cyst is accessory mesonephric duct degeneration imperfection or prostatic vesicle, which is fused at the median line, and forms a deep diverticulum or cyst near the median line under the bladder, opening at the back of the prostate urethra. Acquired cysts are incomplete or intermittent obstruction of acini caused by tough prostatic stroma, which gradually thickens the epithelial cells of acini, and eventually leads to retention cysts, including parasitic cysts, inflammatory retention cysts, and cysts formed by prostate cancer degeneration. Acquired cysts can occur at any part of the prostate or protrude to the bladder neck, with a diameter of 1-2 cm.
Most of the cysts are clear fluid. Smaller cysts are mostly asymptomatic. When the cyst is large, the rectal digital examination touches the cyst on the prostate, and urethrography shows that there is an arc impression on the posterior urethra. Ultrasound and CT can determine its location. Large cysts can cause urinary tract obstruction symptoms such as frequent urination, urgency, poor urination, and residual urine. The rectal digital examination can touch the prostatic cystic mass. Prostate cysts can be complicated by infection and stones. Larger cysts can compress the urethra and cause difficulty in urination. Common symptoms include urgency of urination, frequency of urination, difficulty in urination, thin urine line, and retention of urine. Congenital prostatic cysts are often accompanied by congenital diseases such as hypospadias, cryptorchidism and renal hypoplasia.
