9-13 cm: With an ultrasound evaluation, the normal kidney size is 9-13 cm. One kidney may be up to 1.5 CM difference in size from the other and still be in acceptable range. Kidney sizes in females may be some smaller than in males but evenso a kidney smaller than 9 CM is abnormally small.
Each kidney is scanned in longitudinal section and cross section. The upper pole is located more dorsally than the lower pole, the transducer must be tilted to the dorsum. Transducers use either sector or curved-array technology with 3.5 to 5 MHz. Normal Renal Ultrasound Findings Size if the Kidney. Length: 100â115 mm; Width: 50â70 mm; Depth: 30â50 mm
