Ureter (ureter) is paired tubular body measuring about 25-30 cm, its diameter is 5-7 mm. Extends in the retroperitoneum, for abdominal cavity, but also has a part that enters into the abdominal cavity of the pelvis and a part extending through the wall of the bladder and orifice so called. Trine bladder (deltoid area in the fundus / scum / bladder enclosed outcome ureters and the mouth of the urethra).

Function ureter

Ureter is transported definitive urine produced by the kidneys to the bladder. The plot is active, ie. Through peristalsis. To contractions occur every 10 to 12 seconds. In the case of wedge urinary stone it is the peristaltic movements which form undulující / volatile / pain, i.e. colic.

Peristalsis of the ureter is controlled plexus, in its upper part are known. Pacemaker rhythm indicating neurons, nerve cells. When the inflow of urine into the ureters, urinary spindles formed, ie. Portions of urine in a relaxed part of the ureter. This spindle is further advanced through contraction and relaxation of individual sections of the ureter. In the case of normal urine production at one point located in only one ureter bladder and ureter spindle turns. This condition is known as normotonická response ureters. At increased urine production occurs and the ureters to accelerate peristalsis.

When transporting the urine to the bladder closes the pressure in the filling with urine bladder urethra so as to prevent backflow of urine. The function of the ureters can be recorded using elektrouretrografu.
