Ultrasound
The kidneys are orthotopic and maintain their sizes, outline and parenchyma morphology. The right kidney measures 123 ml while the left kidney measures 174 ml in volume. No renal focal lesions, calculi or features of ureterohydronephrosis bilaterally.
Anterior and frank approaches used to indirectly evaluate the intra-renal (segmental arcuate and interlobar; upper poles, mid poles and lower poles) arterial spectral Doppler waveforms. The renal arteries show normal wall outline/ caliber and also demonstrate low resistance profiles with continuous forward flow throughout the cardiac cycle. The intra-renal arterial waveforms show normal acceleration times and early systolic peak with no pulsus Tardus or pulsus Parvus waveforms.
The renal artery peak systolic velocity is within normal limits bilaterally. The bilateral intra-renal arcuate and interlobar arterial resistive indices of 0.55, 0.56, 0.61, 0.58, ,0.54, and 0.55 for the right kidney and; 0.57, 0.64, 0.65, 0.46, 0.51 and 0.54 for the left kidney noted are within normal limits.
The urinary bladder is unremarkable as well with a pre-void volume of 254 ml and empties completely on voiding with no residue on immediate post voiding examination assessment.
