Anatomy
The normal bladder epithelium consists of transitional cell lining, up to seven cell layers thick. Deep to the urothelium is the subepithelial connective tissue (lamina propria or submucosa) which contains irregularly arranged smooth muscle fibers. The muscularis (detrusor muscle) is adjacent to the lamina propria and is surrounded by perivesical fat.

Genetics
Numerous factors have been reported to be associated with bladder cancer. Al- though some genetic abnormalities have been associated with bladder cancer (p53, Rb, erbB-2, and loci on chromosome 9), these findings have not been uniform. Certain environmental exposures have been shown to correlate with bladder cancer.
The Reservoir : Prostate cancer

The “ideal reservoir” should be compliant and accommodate a large volume under low pressure, without reflux or absorption of urinary constituents. The con- cept of detubularization and folding of the bowel into a spherical form greatly in- creases the storage capacity with significantly lower internal filling pressures without coordinated peristaltic contractions.

In general, patients considered appropriate surgical candidates for radical cystectomy should also be potential candidates for a continent urinary diversion. Relative contraindications relate to the ability of the patient to perform self-catheterization and to care for a neobladder owing to mental or physical impairments. Poor renal and hepatic function should also be considered a contraindication [...]

Pheochromocytoma is the tumor of the adrenal medulla. It produces high levels of catecholamines (epinephrine and norepinephrine) and leads to hypertension, of- ten episodic, but usually sustained. The most common symptoms are hypertension, palpitation, severe pounding headaches, and excessive and inappropriate sweating. Familial heochromocytomas are seen in patients with multiple endocrine neopla- sia (MEN) syndrome.
