Ask-Upmark Kidney: Etiology and Symptoms
Definition of the Ask-Upmark Kidney
The Ask-Upmark kidney is a segmental hypoplasia of the kidney often caused by vesicoureteral reflux (VUR).
The Ask-Upmark kidney is the result of vesicoureteral reflux and chronic pyelonephritis. Segmental hypoplasia with scarring of the renal parenchyma leads to renin release, secondary hyperaldosteronism and arterial hypertension.
Signs and Symptoms of the Ask-Upmark Kidney
- Severe arterial hypertension
- Onset around the 10th year of life
- Hypertensive retinopathy
- Patients with bilateral manifestation are at risk for end-stage renal failure.
Treatment of Ask-Upmark Kidney
Unilateral Ask-Upmark kidney with severe hypertension is treated with nephrectomy. Medical treatment of arterial hypertension and chronic kidney disease is crucial for bilateral disease.
