What is hyperalgic nephritic colic?

- It corresponds to a pain of nephritic colic not calmed by a symptomatic analgesic treatment well conducted with use of NSAID IV and morphine IV in titration. - It then requires hospitalization with reassessment of pain. If the pace and severity of crises do not disappear, emergency urine drainage is necessary. - Sometimes, the pain arises suddenly. This corresponds to the rupture of the excretory pathway or rupture of fornix (junction of the excretory pathway on the renal straw) . In this case, if the obstacle persists, it can cause a large perineal urinoma, also requiring emergency drainage of the excretory tract.
