Urostomy is most commonly performed after cystectomy, such as may be necessary in, for example, bladder cancer.Other indications include severe kidney disease, accidental damage or injury to the urinary tract, surgical complications because of non-related pelvic or abdominal surgery, congenital defects that cause urine to back up into the kidneys, or urinary incontinence.
Capillaria plica (dog bladder worm) is a parasitic nematode which is most often found in the urinary bladder, and occasionally in the kidneys, of dogs and foxes. [1] It has also been found in the domestic cat , and various wild mammals .
Hydronephrosis can also result from the retrograde flow of urine from the bladder back into the kidneys (vesicoureteral reflux), which can be caused by some of the factors listed above as well as compression of the bladder outlet into the urethra by prostate enlargement or fecal impaction in the rectum (which sits immediately behind the ...
In the top-right image, the cystoscope has been bent within the bladder to look back on itself. The bottom two images show an inflamed urethra. If a patient has a stone lodged higher in the urinary tract, the physician may use a much finer calibre scope called a ureteroscope through the bladder and up into the ureter. (The ureter is the tube ...
[1] [2] Urine normally travels in one direction (forward, or anterograde) from the kidneys to the bladder via the ureters, with a one-way valve at the vesicoureteral (ureteral-bladder) junction preventing backflow. The valve is formed by oblique tunneling of the distal ureter through the wall of the bladder, creating a short length of ureter (1 ...
The urinary bladder is the organ that collects urine from the kidneys. It is a hollow muscular , and distensible (or elastic) organ, and sits on the pelvic floor . Urine enters the bladder via the ureters and exits via the urethra during urination .
A nephrostomy is performed whenever a blockage keeps urine from passing from the kidneys, through the ureter and into the urinary bladder. Without another way for urine to drain, pressure would rise within the urinary system and the kidneys would be damaged. [4] The most common cause of blockage necessitating a nephrostomy is cancer, especially ...
Additionally, reflux of urine from the bladder back up the ureters is a condition commonly seen in children. 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.
