Computed tomography detected pyelovenous backflow associated with complete ureteral obstruction

INTRODUCTION: Pyelovenous backflow is a rare condition resulting from an increase in pressure in the renal pelvis due to urinary obstruction. CASE PRESENTATION: A 49‐year‐old woman developed high‐grade fever and right‐sided hydronephrosis after undergoing hysterectomy. Although the hydronephrosis wa...

description INTRODUCTION: Pyelovenous backflow is a rare condition resulting from an increase in pressure in the renal pelvis due to urinary obstruction. CASE PRESENTATION: A 49‐year‐old woman developed high‐grade fever and right‐sided hydronephrosis after undergoing hysterectomy. Although the hydronephrosis was mild, retrograde pyelography revealed complete obstruction of the right ureter. Excretory phase scans of contrast‐enhanced computed tomography showed pyelovenous backflow, which presumably decompressed the hydronephrosis. The pyelovenous backflow immediately disappeared after ureteroneocystostomy. CONCLUSION: We were presented with a patient showing pyelovenous backflow detected by contrast‐enhanced computed tomography, which completely disappeared after ureteral obstruction release.
