The prostate belongs to the male reproductive system, and the urethra belongs to the urinary system. However, due to the close anatomical position of the male genitourinary organs, the relationship between the two is very close.
The prostate is located below the bladder and above the urogenital septum. The urethra passes through the center of the prostate, and the prostate wraps around the urethra. The section of urethra surrounded by the prostate is called the urethra prostate. It starts from the bladder neck and directly reaches the urogenital septum, with an average length of about 3 cm. This section of urethra runs through the whole prostate from the bottom to the top, and is located in the prostate parenchyma. It is slightly narrow at both ends and widened in the middle, which is the largest diameter of male urethra. On the posterior wall of the urethral prostate, its median line is a longitudinal ridge, called the urethral ridge. The central protrusion of the urethral ridge expands into a dome, which is called the seminal caruncle. The center of the seminal caruncle has a round or slender longitudinal fissure, called the prostate sac. Below the prostate sac are the openings of two ejaculatory tubes. The groove on both sides of the urethral ridge, called the prostatic sinus, has many openings for the prostatic excretory tube, from which the prostatic fluid can be discharged into the urethra.
When the prostate is hyperplastic, the enlarged prostate can compress the prostate of the urethra, making it tortuous and narrow, resulting in difficulty in urination. Inflammation of the prostate is often associated with inflammation of the urethra and prostate. Similarly, diseases of the urethra and prostate can also affect the prostate. Therefore, the prostate and urethra are closely related in anatomy, physiology and pathology.
