What are the Ureters?

Although their functions may appear simple, the ureters perform essential excretory work for the body. These two slender tubes transport urine from the kidneys to the bladder. The ureters use a process called peristalsis, the contracting, rhythmic movement of smooth muscles, to push the urine into the bladder. The organs prevent urine from backing up or standing still, which protects the body from developing kidney and bacterial infections.

The ureter is my friend

Our training, our specialty, our daily work as Gynaecologists is associated with the imperative anxiety to harm the ureter. WE FEAR THE URETER! Well, lets take it to another level and not talk about fear and complication avoidance. But rather about friendship and managing the relationship with our friend, the ureter, in a positive way. "The ureter is our friend“. Remembering the efficient, respectful but fearless dissection of the ureter, pushing it away from affected tissue, I understand that the implications of the ureter being a friend are:

The Ureters

The Ureter Proper measures from 25 to 30 cm. in length, and is a thick-walled narrow cylindrical tube which is directly continuous near the lower end of the kidney with the tapering extremity of the renal pelvis. It runs downward and medialward in front of the Psoas major and, entering the pelvic cavity, finally opens into the fundus of the bladder.

Ureter: Anatomy, Functions and Disorders

The ureter is a muscular tube in the urinary system that connects each kidney to the urinary bladder. Its primary function is to transport urine from the kidneys, where it’s produced, to the bladder, where it’s stored until expelled from the body during urination. The ureter employs peristaltic contractions to propel urine downward, overcoming gravity. Common disorders of the ureters include obstruction, stricture, reflux, injury, calculi, and tumors. Congenital anomalies, such as UPJO, duplex collecting systems, ureteral duplication, ectopic ureter, ureterocele, and ureteral atresia, can affect its structure and function.

Ureters

The ureter is a fibro muscular tube, which is 41 to 46 cm long, through which the urine passes from the kidneys to the bladder. Present in each of the two kidneys, the duct mucosal muscle can ideally be divided into an abdominal portion and a pelvic portion (since it originates in the abdomen and ends in the urinary bladder).

Uro-words making history: Ureter and urethra

The history of the terms “ureter” and “urethra” is exemplary of the difficulties with which the development of a precise urologic terminology had to struggle. The story behind the words also clarifies why even today we still have imprecise or misleading terms.

What are Ureters?

The ureters have been identified for at least two thousand years, with the word "ureter" stemming from the stem uro- relating to urinating and seen in written records since at least the time of Hippocrates.

The ureters are collapsible S-shaped channels, each about 25 cm in length. They are widest at the renal pelvis and narrow progressively as they enter the urinary bladder in the concavity of the true pelvis.

StatPearls

The ureters are bilateral thin tubular structures with a 3 to 4 mm diameter that connect the kidneys to the urinary bladder. These muscular tubes transport urine from the renal pelvis to the bladder. The ureter's muscular layers are responsible for the peristaltic activity that moves urine from the kidneys to the bladder.

The ureters are two thick tubes which act to transport urine from the kidney to the bladder. They are approximately 25cm long and are situated bilaterally, with each ureter draining one kidney.The Ureters
