Recto-Uterine Recess

The rectal uterine cavity, or excavatio recto-uterina PNA, BNA, JNA (Pocket of Douglas, Douglas space), is the space between the rectum and the uterus. It gets its name from the Latin term excavatio, which means “to dig up,” due to the fact that during pregnancy the uterus increases in size and becomes deeper into the pelvis, while the rectum moves up and to the side. This space is also called the intraperineovaginal canal, which means “inside the perineovaginal canal” (the cavity between the skin of the perineum and the vagina). Unfortunately, the area associated with this canal is often susceptible to infections due to friction in the perineal area, as well as insufficient hygiene procedures in this area. To prevent infections, it is not recommended to use baths, saunas and swimming pools. And to prevent tissue enlargement and enlargement after childbirth, special training of the pelvic muscles is recommended. Common infections in this area: cystitis, inflammatory diseases of the uterus, inflammatory processes of the intestines and pelvis (pyelonephritis, peritonitis, adnexitis, etc.). To cure diseases in this area, it is necessary to contact a gynecologist and an infectious disease specialist.

Rectum - Uterine Recess

The rectum - uterine recess is the area between the rectum and the uterus, which has many important functions. This space is a unique anatomical structure that is divided between two separate reproductive organs - the uterus and the rectum.

**Histological features of the PMU:** 1. The inside of the CME is surrounded by loose connective tissue, and behind the CME is due to the wide fascia into which the levators are sandwiched, which contributes to the stable location of the CME relative to the pelvic walls. 2. From the inner edge of the KMO in
