Pelvic actinomycosis presenting as ureteric and rectal stricture

Simultaneous ureteric and rectal stricture due to pelvic actinomycosis is very rare and only a few cases of either rectal or ureteric stricture have been reported. Our aim is to report a case of stricture of the rectum and the right ureter due to pelvic actinomycosis infection in a 63-year-old man.

Explorative laparotomy and biopsies of the inflammatory pelvic mass were the only procedures that led to the definitive diagnosis of actinomycosis. Temporary diverting colostomy, drainage of the right ureter by a pigtail catheter and postoperative treatment with appropriate antibiotics were successful in eradicating the inflammatory process.

Extensive pelvic masses involving pelvic viscera should be biopsied before undertaking any major surgery because of the possibility of pelvic actinomycosis.
