Detrusor-sphincter dyssynergia refers to failure of the urethral sphincter to relax during detrusor contraction. The cause is a central nervous system lesion located between the brain stem micturition center and the sacral spinal cord. This is an extremely rare condition in cats. It may be confused with a failure of urethral relaxation due to local urethral causes such as inflammation or edema. This article reviews detrusor-sphincter dyssynergia to allow the reader to distinguish this rare condition from more common conditions that prevent bladder emptying.

D009119 Muscle Contraction A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

D009130 Muscle, Smooth Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant.
