Abstract:
Cerebrovascular accident and renal hypertension secondary to ureteropelvic junction obstruction (UPJO) are extremely rare. A 6-year-old girl presented with intracranial hemorrhage because of hypertension secondary to the bilateral UPJO. This was successfully treated with craniotomy and subsequent percutaneous nephrostomy placement and bilateral pyeloplasty. Brain computerized tomography revealed right-sided intracranial hemorrhage, and renal ultrasonography confirmed bilateral severe hydronephrosis. Craniotomy with evacuation of intracerebral hematoma and bilateral nephrostomy under ultrasound guidance were performed. One week later, she underwent bilateral pyeloplasty in 2 stages. The patient has been well with normalized renal function and is completely cured of her hypertension in long-term follow-up.
