[Acute abdomen masking pyelonephritis (author's transl)].

Analysis of 10 case histories shows that the picture of the acute abdomen may predominate in acutely exacerbated pyelonephritis. Viscero-dermal reflexes with hyperalgesia and muscular defense, visero-visceral organ reflexes with shock, vomiting, meteorism and disturbances of intestinal motility and metabolic acidosis are temptations to laparotomy. Fever in particular, pathological urinalysis, renal acidosis and occasionally hyperchloremia suggest the diagnosis of "abdominal type of acutely exacerbated pyelonephritis".
