  Bladder Cancer - Patient Guide - UrologyChannel
Bladder cancer accounts for approximately 90% of cancers of the urinary tract (renal pelvis, ureters, bladder, urethra).
Urine is produced by the kidneys, carried to the bladder by the ureters, and discharged from the bladder through the urethra.
Bladder cancer usually originates in the bladder lining, which consists of a mucous layer of surface cells that expand and deflate (transitional epithelial cells), smooth muscle, and a fibrous layer.

The peritoneum is carried by it from the vertex of the bladder on to the abdominal wall to form the middle umbilical fold.
The vertex of the bladder is joined to the umbilicus by the remains of the urachus which forms the middle umbilical ligament, a fibromuscular cord, broad at its attachment to the bladder but narrowing as it ascends.
The nerves of the bladder are (1) fine medullated fibers from the third and fourth sacral nerves, and (2) non-medullated fibers from the hypogastric plexus.

At the lowest part of the urinary bladder (known as the neck) is an opening into a tube-shaped structure known as the urethra that drains urine from the body.
The opening from the bladder to the urethra is normally kept tightly closed by a circular muscle known as a sphincter.
The urinary bladder is also known as the bladder, vesica urinaria, vesica, urocyst, urocystis, and cystis urinaria.

 AllRefer Health - Urinary Tract Infection (Bladder Infection, Cystitis, UTI)
A urinary tract infection, or UTI, is an infection that can happen anywhere along the urinary tract -- the kidneys, the ureters (the tubes that take urine from each kidney to the bladder), the bladder, or the urethra (the tube that empties urine from the bladder to the outside).
Most commonly, infections affect the lower urinary tract (bladder and urethra), which is called cystitis.

 Urinary
Cats with urinary problems typically strain to urinate or make frequent trips to the litter box and get in the position but not much comes out; that's because the bladder is more or less empty, but the inflammation and irritation of the disease makes them think it's time to go.
Thus, a urolith is a urinary tract stone that may be located in the kidneys (nephrolith; nephro is Greek for kidney), ureters (ureterolith), urinary bladder (urocystolith), or urethra (ure-throlith).
Meanwhile, a few comments.  Most urinary tract problems turn out to be short lived bladder infections that quickly respond to a short course of antibiotics and anti-inflammatories.  Many of our seminar speakers on the subject go as far to say that many urinary tract "infections" are not infections at all and would heal without treatment.

Urinary obstruction is one of the most common causes of chronic and acute renal failure.
The symptoms of urinary obstructions are not immediately visible and thereby the risk is greater for internal damage by the time a patient manifests the symptoms.
Since the extent and time of the obstruction are the two main factors leading to renal dysfunction, it is important that these be diagnosed and treated as early as possible to prevent renal loss.
