Ultrasound Kidney Length (US-KL)

US-KL alone can be used to determine whether there is risk of rapid disease progression in ADPKD.*1

MRI is the recommended imaging modality for the most accurate and reproducible measurement of kidney length, kidney cyst burden, and TKV. As such, MRI/CT-calculated TKV is a strong predictor of future renal insufficiency in ADPKD. However, US-measured KL is a useful surrogate when MRI/CT-calculated TKV is not feasible.1

US-measured predictor of rapid progression KL > 16.5 cm in patients less than 45 years old

when rapid progression is defined as CKD stage 3 development within 8 years1,2

Kidney Length > 16.5 cm
