Ketamine-associated CT findings of damage in liver and gall and urinary system

Objective: To investigate the image signs of damage e in urinary system and liver and gall system and diagnostic value of CT findings in abuse of ketamine. Methods: With ethics committee approval, a retrospective analysis of 10 patients with a history of taking K powder (1 to 10 years) was done with abdominal CT scan and enhanced scan data to analysis the imaging findings of ketamine-related abdominal organ damage. Results: CT images of the 10 patients showed different degrees of reduced bladder capacity, bladder wall thickening range of 3∼14 mm. Of which the wall were thickened on both sides with the waist-shaped in 5 patients. Bilateral hydronephrosis and hydroureterosis was found in 3 cases with uniform wall thickening of both ureters. 4 cases of renal multi-lesion papillary necrosis was found, of which 2 patients showed multi-lesion ischemic changes in renal parenchyma in both kidneys. Expansion of the common bile duct appeared in 3 cases, of which 2 cases with merger intrahepatic bile duct dilation. Conclusion: CT findings of ketamine associated abdominal organ injuries in the bladder and renal may have certain characteristics. It is helpful to make diagnosis with the combination of favorable clinical data and medical history. (authors)
