Ultrasound

Ultrasonography is the preferred tool for the diagnosis of ADPKD due to its safety profile and low cost. In patients with a positive family history, the diagnosis of ADPKD is based on the detection of bilateral fluid-filled renal cysts. Ultrasound imaging is highly sensitive and can detect cysts > 1 cm in diameter. The diagnostic criteria include:

• Two or more unilateral or bilateral cysts in patients <30 years old
• Two or more cysts in each kidney in patients 30-59 years old
• Four or more cysts in each kidney in patients ≥60 years of age or older.
