Ureteral calculi, for one.
Ureteral calculi, for one.
Because of the one-way valve system of the ureters, which connect the kidneys to the bladder. If these ureter valves do not work properly, they can cause urine to back-flow into the ureters and toward the kidneys.
Bladder
Urine is stored in the bladder before excretion.
The bladder.
Your bladder stores your urine until you want to eliminate it.
If the Urine is in the bladder and does not flow, you put a catheter through the urethra.
While emptying the bladder, the last step is the emptying of the bladder via the urethra. The urethra sends urine out of the bladder while preventing the back-flow of the urine using a back-flow valve mechanism.
A urine flow test can indicate problems in bladder function, such as an obstruction, that will need further tests to diagnose.
The job of the Uriter is to handle the flow of urine from the Kidney's to the bladder.
Kidneys, ureters, bladder, urethra
This sphincter is around the neck of the bladder. This, with the internal sphincter, control the flow of urine from the bladder.
Urinary bladder mainly contains two types of musces 1. Smooth muscles, forming the wall of the bladder ( Detrusor muscle ) and the internal urethral sphincter ( which controls the flow of urine which is involuntary ), and 2. Skeletal muscle, which forms the external urethral sphicter with which we can control the flow of urine.. ( voluntary control of flow )
AlkaptonuriaVesicoureteral reflux is the backflow of urine into the kidneys.
The bladder stores urine before it is urinated out of the body.
Ureters go from the pelvis of the kidney into the urinary bladder. From the urinary bladder, the urethra is the tube that carries the urine to the outside the ureters are tubes that exit the kidneys at the Hilus, coveying urine into the bladder, approximatly 25cm long. The urethra exits the bladder and takes urine out of the body, in males it is approximatly 20 cm long, females 3-4 cm long. Ureter is the (tube) flow channel from kidney to bladder, Urethra is the (tube) flow channel from the bladder to the outside of your body.
Normally, a ureteral stent re-establishes the flow of urine from the kidney to the bladder. Postoperative urine flow will be monitored to ensure the stent has not been dislodged or obstructed.
kidneys produce urine & its collected in the bladder for excecretion.
