Overview
Complications of unilateral renal agenesis (URA) may include signs of renal injury such as: hypertension, microalbuminuria and chronic kidney disease. Prognosis of bilateral renal agenesis (BRA) is extremely poor, and the mortality rate is 100% without prenatal therapy with serial amnioinfusion.
Natural History, Complications, and Prognosis
Natural History
Patients with unilateral renal agenesis (URA) may usually be asymptomatic but may progress to renal insufficiency and end stage renal disease (ESRD).[1]
Complications
Complications of unilateral renal agenesis (URA) may include signs of renal injury such as:[2]
- Hypertension (16%)
- Microalbuminuria (21%)
- GFR <60 mL/min/1.73 m² (chronic kidney disease) (10%)
Prognosis
- Prognosis of bilateral renal agenesis (BRA) is extremely poor, and the mortality rate is 100% without prenatal therapy with serial amnioinfusion.[3]
- URA has a better prognosis compared to BRA.[4]
