RECTAL DRAINAGE - UNUSUAL EVOLUTION OF A PSOAS ABSCESS

We report two cases of primary psoas abscess in two patients of 15 mon ths and 4 years of age. As the first case showed the natural history o f this process the second one was large enough to produce a huge urete rohydronephrosis and to drain through the rectal wall to the rectum sp ontaneously, although this natural way did not achieve complete draina ge. Both were treated by open drainage and systemic antibiotics with g ood response. They were discharged at the 7th and 12th postoperative d ay. 5 months later no complication has come up. Etiological, clinical and therapeutic aspects of this unusual pathology are reviewed.
