Current methods of bladder reconstruction include the use of gastrointestinal tissue. However, while this method is effective in improving the function of the bladder, it can actually increases the risk of cancer, and can cause other complications, such as infections, urinary stones, and electrolyte imbalance.
The trigone (also known as the vesical trigone) [1] is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, stretch receptors in the urinary bladder signal the brain of its need to empty ...
The bladder (from Old English blædre ' bladder, blister, pimple ') is a hollow organ in humans and other vertebrates that stores urine from the kidneys.In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination.
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites , and regulate blood pH .
The bladder also contains β 3 adrenergic receptors, and pharmacological agonists of this receptor are used to treat overactive bladder. The mucosa of the urinary bladder may herniate through the detrusor muscle. [6] This is most often an acquired condition due to high pressure in the urinary bladder, damage, or existing connective tissue ...
The urinary bladder forms from the urogenital sinus. Over time, as the bladder enlarges, it absorbs the surrounding parts of the primitive ureters. [ 8 ] Finally, the entry points of the ureters into the bladder move upwards, owing to the upward migration of the kidneys in the developing embryo.
Papillary urothelial neoplasm of low malignant potential (PUNLMP) is an exophytic (outward growing), (microscopically) nipple-shaped (or papillary) pre-malignant growth of the lining of the upper genitourinary tract (the urothelium), which includes the renal pelvis, ureters, urinary bladder and part of the urethra.
The urinary bladder is formed partly from the endodermal cloaca and partly from the ends of the Wolffian ducts. In other words, the allantois takes no share in its formation. After the separation of the rectum from the dorsal part of the cloaca, the ventral part becomes the primary urogenital sinus. [2]
