URINARY RETENTION AND SPACE-OCCUPYING LESIONS OF THE FRONTAL-CORTEX

The authors present 2 cases in which urinary retention was related to supratentorial cortical lesions. These cases support the presence and function of a supratentorial center involved in control of the voiding reflex loop and indicate that lesions affecting this center can resul t in urinary retention rather than the syndrome of incontinence, urgen cy, and increased urinary frequency that is generally attributed to dy sfunction of this system. In such cases, a clinical presentation of ur inary retention in the absence of associated remarkable neurological d eficits renders clinical evidence as a localizing sign.
