Renal sonography is frequently employed to exclude obstructive uropathy in patients with uremia. Sonographic findings of moderate bilateral hydronephrosis were encountered in a dehydrated patient undergoing rehydration. Subsequent excretory urography and a follow-up renal sonogram were normal. To investigate the possibility that hydration and bladder distension in an otherwise normal and unobstructed collecting system could result in hydronephrosis detectable by ultrasound, 23 apparently normal volunteers underwent renal sonography in the hydrated and basal states. The filled urinary bladder in a patient undergoing hydration frequently results in the sonographic appearance of hydronephrosis.
肾脏超声检查常用于排除尿毒症患者的梗阻性尿路病。一名正在接受补液治疗的脱水患者出现了双侧中度肾盂积水的超声检查结果。随后的排泄性尿路造影和肾脏超声复查结果均正常。为了研究在原本正常且无梗阻的集合系统中，补液和膀胱充盈是否会导致超声检查可检测到的肾盂积水，23名看似正常的志愿者在补液状态和基础状态下接受了肾脏超声检查。正在接受补液治疗的患者膀胱充盈时，超声检查常显示肾盂积水。
