Some children develop a pattern of dysfunctional voiding or abnormal urination in which the muscle groups of the urinary tract do not work together in a coordinated manner.
Instead, the bladder and sphincter muscles strain against each other (also called detrusor-sphincter dyssyngeria), which can cause increased bladder pressures, incomplete bladder emptying, and possibly urine backflow to the kidneys.
This process can also lead to involuntary daytime urine accidents or wetness, as well as other undesirable consequences including urinary tract infections, hydronephrosis, and kidney damage. It is necessary to change this uncoordinated pattern of voiding in order to improve urinary tract health.
