Radiographs and point of care ultrasound demonstrated retroperitoneal and peritoneal effusion. Diagnostic abdominocentesis confirmed hemorrhagic effusion. Complete blood count, biochemistry, and coagulation profile showed a regenerative anemia (PCV 32%), thrombocytopenia (platelets 96\u00a0\u00d7\u00a010<jats:sup>9<\/jats:sup>\/L [96\u00a0\u00d7\u00a010<jats:sup>3<\/jats:sup>\/\u00b5l]), azotemia (BUN 38.9\u00a0mmol\/L [109\u00a0mg\/dl], creatinine 512.8\u00a0\u00b5mol\/L [5.8\u00a0mg\/dl]), and coagulopathy (prothrombin time &gt;100\u00a0s, activated partial thromboplastin time &gt;42.3\u00a0s). The client reported access to anticoagulant rodenticide up to 72\u00a0hours prior to presentation. Ultrasonographic examination revealed bilateral pyelectasia and hydroureter with thickened distal ureteral walls at the level of the ureteral\u2013vesicular junctions. The ultrasonographic conclusion was presumptive intramural ureteral hemorrhage resulting in ureteral obstruction. The patient was diagnosed with AKI with likely prerenal, renal, and postrenal components. Treatment included vitamin K and frozen plasma transfusion. The patient recovered fully and was discharged 3\u00a0days after presentation. Two days after discharge, the patient had improvement in azotemia (BUN 10.7\u00a0mmol\/L [30\u00a0mg\/dl], creatinine 176.6\u00a0\u00b5mol\/L [2.0\u00a0mg\/dl]). Gas chromatography\u2013mass spectrometry confirmed presence of diphacinone in the blood. Repeat ultrasound and biochemistry 60 and 210\u00a0days, respectively, after discharge showed resolution of ureteral wall thickening, hydroureter, pyelectasia, and recovery of kidney parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title>New or Unique Information<\/jats:title><jats:p>Although nephropathies secondary to anticoagulant therapy have been described in people, the
