Abstract
Thirty four kidneys in 26 patients demonstrating all grades of hydronephrosis were examined with B scan ultrasound. In moderate hydronephrosis, the pelvic echo pattern has a C, ring, or ovoid shape. Severe hydronephrosis may be recognized by a series of cyst like echo patterns radiating from the pelvis or the development of a featureless, sonolucent sac. In ureteropelvic junction obstruction, a 'figure 8' double circle pattern may occur.
