[Acute abdomen secondary to pyonephrosis. Perinephritic abscess with fistula to peritoneal cavity].

OBJECTIVE

To describe a case of acute abdomen arising from an underlying urological condition.

METHODS/

RESULTS

Herein we describe a patient with acute abdomen arising from a pyonephrotic kidney with fistulization to the peritoneal cavity. The clinical manifestations disappeared following nephrectomy by the anterior approach and drainage of the intraperitoneal cavity.

CONCLUSION

Although infrequent, it should be taken into account that peritoneal abscess and/or pyonephrosis can cause acute abdomen when they fistulize to the peritoneal cavity.
