Abstract:
Various types of bladder dysfunction are associated with urinary tract infection, renal damage and vesicoureteral reflux (VUR). In this article the influence of functional bladder disturbances such as detrusor instability (overactive bladder, OAB) and bladder sphincter dyssynergia (dysfunctional voiding), on the resolution of vesicoureteral reflux are reviewed. In summary, it is important to distinguish between children with dysfunctional voiding (increased activity of the pelvic floor during voiding) and those with OAB (detrusor overactivity during filling) because the latter has less effects on VUR.

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...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
