The tube that carries urine from the kidneys to the bladder is known as the ureter. The ureters are long, thin tubes that connect the kidneys to the bladder and play a crucial role in the urinary system. Function of the Ureters: The primary function of the ureters is to transport urine from the kidneys to the bladder. Once urine is produced in the kidneys, it flows down through the ureters into the bladder, where it is stored until it is expelled from the body through the urethra. The ureters also help maintain the flow of urine by preventing backflow from the bladder to the kidneys. Structure of the Ureters: The ureters are approximately 10-12 inches long and are made up of three layers: an inner mucous membrane, a muscular middle layer, and an outer fibrous layer. The muscular layer of the ureters contracts in a wave-like motion to propel urine towards the bladder, a process known as peristalsis. Common Ureteral Disorders: Several conditions can affect the ureters, including kidney stones, ureteral strictures, and ureteral obstructions. Kidney stones are solid masses that form in the kidneys and can become lodged in the ureters, causing pain and potential blockages. Ureteral strictures are narrowed areas in the ureters that can impede the flow of urine, while obstructions can occur due to tumors or other blockages. If you are experiencing symptoms such as severe back pain, blood in the urine, or difficulty urinating, it is important to seek medical attention promptly. A healthcare provider can perform tests such as imaging studies or a ureteroscopy to diagnose and treat any issues with the ureters. For more information on the ureters and the urinary system, visit Mayo Clinic or Urology Health. In conclusion, the ureters are vital structures in the urinary system that transport urine from the kidneys to the bladder. Understanding the function and structure of the ureters can help individuals recognize and address any potential issues with their urinary health.
