[Bladder sphincter disorders in multiple sclerosis: symptomatology and evolution. 100 cases]

The semiology and evolution of vesicosphincteral disorders have been studied in a series of 100 cases of multiple sclerosis. All the patients underwent a complete checkup and were followed over a period of 6 years. Mictional problems appear within the first five years in 60 p. cent of cases. When they occur later on, they tend to follow the evolution of the disease on their own. There exist regular correlations between the gravity of the motor and sphincteral handicap, and between the size of the postmictional residue (over 20 p. cent of the miction), the time elapsing since the onset of the mictional disorders, and the appearance of uronephrological complications.
