Renal hypertension secondary to perirenal pseudocyst: resolution by percutaneous drainage

We report a case of renal hypertension 6 months after a panhysterectomy for cervical cancer. Clinical investigation revealed that recurrent cancer obstructed the left ureter, resulting in the formation of a gigantic perirenal pseudocyst and, subsequently, hypertension. Constriction of the renal parenchyma was responsible for the overactivity of the renin-angiotensin system (the Page phenomenon). Ultrasound-guided percutaneous drainage relieved the symptomatology completely.
