What are the criteria for dividing the upper, middle, and lower segments of the ureter?

The standard of upper, middle, and lower segments of the ureter is segmented based on some body surface landmarks. The standard of upper, middle, and lower segments of the ureter generally refers to the location of the upper, middle, and lower segments of the ureter, which aids in the auxiliary diagnosis of the location of diseases. It is recommended to promptly undergo detailed examinations at a formal nephrology department of a hospital, and the segmentation should be carried out according to reasonable methods.

The ureter originates from the end of the renal pelvis and terminates at the bladder, with a total length of approximately 20 to 30 centimeters. It includes the abdominal segment, pelvic segment, and bladder of the ureter. The upper end of the ureter is generally located at the connection site between the renal pelvis and the ureter, the middle segment is located at the connection site between the ureter and the bladder, and the lower segment is mainly located at the connection site between the bladder and the urethra. The upper, middle, and lower segments can be distinguished based on the length of the ureter.

It is usually possible to promptly understand the health status of the ureter. It is necessary to regularly maintain the ureter to prevent damage to it, which may affect the health of the urinary system and cause urinary system diseases such as frequent urination and incomplete urination, which may affect normal urination.
