What are the differences between prostatic calculi and urethral calculi in the prostate region?

Patient's question:

How to distinguish between prostatic calculi and urethral calculi in the prostate region in clinical diagnosis?

Doctor's answer:

The prostate itself is an organ, and prostatic calculi refer to the recurrence of stones within the prostate gland. Prostatic urethral calculi are a type of urethral calculus. Since the prostate is located posteriorly and inferiorly in the urethra, it consists of two chestnut-sized tissues, while the urethra is a long and narrow tube. The prostate is situated in the adjacent area of the middle segment of the urethra. Therefore, this refers to the discovery of stones in a segment of the urethra located at the prostate region.
If there are stones inside the urethra, symptoms such as urine splitting, incomplete urination, and a lack of smooth flow may occur, which are relatively obvious. Prostatic calculi may also cause urinary difficulties, but these symptoms are often less pronounced or even absent.
