A prostate cyst with a diameter of 6mm is generally not serious, and most patients do not experience discomfort. For such cases, there is no need for special treatment; it is only necessary to recheck the ultrasonography every six months to a year to monitor any changes in the size of the cyst. If the cyst continues to grow and presses on the urethra, causing symptoms such as frequent urination, incomplete bladder emptying, or urgency, warm water sitz baths or local physiotherapy can be used for improvement. If the cyst is large enough to block the urethra, causing urinary retention or severe difficulties in urination, it is recommended to undergo surgery as soon as possible to remove the cyst and restore urinary flow.
