Definition

Infantile polycystic kidney disease is an autosomal-recessive disorder.

Clinical Features

  • Incidence

    It occurs in 1:6000–1:14,000 live births.

  • Age

    It affects both children and adults.

  • Sex

    Slight male predominance is reported (male-to-female ratio 2:1).

  • Site

    The kidneys are bilaterally involved.

  • Treatment

    For patients who survive infancy, approximately 50% require dialysis by age 20 due to renal failure.

  • Outcome

    Children develop arterial hypertension and end-stage renal failure. Hepatic fibrosis and biliary dysgenesis are frequent. Approximately one third die of lung hypoplasia. No association with renal neoplasms has been documented.

Macroscopy

In this condition, the kidneys are symmetrically enlarged and retain a reniform configuration and appear diffusely sponge on section. The parenchyma exhibits cylindrical dilated collecting ducts radiating from the medulla to the cortex, their long axis perpendicular to the renal surface, obscuring the cortical-medullary junction.
