Abstract:
Intravesical capsaicin has been used in the management of selected patients with urge urinary incontinence throughout this decade, but the past 12 months has seen considerable interest in this and related compounds. It is no coincidence that during the same period the capsaicin receptor was cloned and named the vanilloid receptor subtype 1 and the European dual centre study of intravesical capsaicin reported that overall 80% of patients derived some clinical benefit. In spite of this, ultrapotent capsaicin analogues such as resiniferatoxin, which also interact with the vanilloid receptor subtype 1, are being studied. Preliminary reports of the potential advantages of intravesical resiniferatoxin are beginning to emerge, and in the future drugs that manipulate the vanilloid receptor may become universally important in the management of neurogenic overactive bladders.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
