Computed tomographic findings in suburothelial hemorrhage

Area of Science:

• Radiology
• Urology
• Hematology

Background:

• Retroperitoneal hemorrhage with renal pelvis and proximal ureter involvement is a known complication of coagulation defects.
• Previous literature has focused on urographic characteristics of this condition.
• Computed tomography (CT) findings have not been previously reported.

Observation:

• This report describes the CT findings in two cases of retroperitoneal hemorrhage.
• Case 1 involved thrombocytopenia secondary to leukemia.
• Case 2 involved anticoagulant therapy in a patient with Budd-Chiari syndrome.

Findings:

• CT imaging can visualize intramural hemorrhage into the renal pelvis and proximal ureter.
• Specific CT features associated with coagulation defects causing this hemorrhage are presented.
• The utility of CT in diagnosing and characterizing this specific complication is demonstrated.

Implications:

• CT provides valuable diagnostic information for retroperitoneal hemorrhage involving the renal pelvis and ureter.
• Understanding these CT findings aids in the diagnosis and management of patients with coagulation defects.
• This study expands the known imaging characteristics of a rare urological complication.
