👉 The term "perinephric" is a medical term that refers to the area of the abdomen where the urethra enters the female pelvis. In humans, this area is also known as the ureteric opening or urethral meatus. The urethra is the tube through which urine flows from the bladder into the urethral sphincter, which then seals off the urethra and prevents it from being swallowed by food or water.
