[Medical treatment of ureteral calculi]

Antiinflammatory drugs are the first choice in the treatment of the acute nephretic colic. This is due to their fast and direct action on the ureteral wall. The use of antispasmodics are still controversial and opioïds are not indicated. During the acute crisis, an hydric restriction should be associated to the medical treatment. After the crisis an increase of diuresis could help to "wash out" the stone. A spontaneous elimination can be expected, especially if the stone is small and located in the third part of the ureter. The ureteral rupture is rare but serious and must be treated by antibiotics and some time to be drained. The rapidity of a more aggressive treatment is function of numerous factors.
