Hematuria Dysuria Palpable mass Guided biopsy/cystocenteisis Monitor Therapy
*View ultrasound urogenital lecture; slide 3
Left kidney.
Long axis and short axis
*Looks like tomato
*View ultrasound urogenital lecture; slide 5
Right kidney lives in the renal fossa of the liver.
*Observe mild pelvic dilation.
Renal pelvis dilation..
Mild
Physiologic
Acute pyelonephritis
Early obstruction
Renal pelvis dilation..
Moderate or severe dilation..
Pyelonephritis or obstructive nephropathy.
Are the ureters normally seen on ultrasound?
NO

Pyelectasia (dilation of the renal pelvis)
*View ultrasound urogenital lecture; slide 9 + 10
Hydronephrosis
If both of the ureters are dilated.. the problem is in the..
bladder!
