The urograms of 186 boys and 145 girls were scrutinized in order to reveal the incidence of ureteral jets demonstable during intravenous pyelography (IVP). In this series a unilateral jet was observed in 26 cases and a bilateral jet in 6 cases. Ureteral jets were almost three times as common in patients with normal urograms compared with those revealing urinary abnormalities. The incidence of a positive jet sign, usually unilateral, varies with the employed technique of examination, but the highest incidence in routine IVP seems to be about 30%. Although infrequent, significant ipsilateral vesico-ureteral reflux (VUR) may occur. This fact together with the reported low rate of bilateral jets restricts the value or Unilateral jets being used as an indicator of absence of gross VUR. The need for micturition cysto-urethography (MCU) at the uro-radiological work-up remains unchallenged.
对186名男孩和145名女孩的尿路造影进行了仔细检查，以揭示静脉肾盂造影（IVP）期间可显示的输尿管喷射的发生率。在该系列中，观察到26例单侧喷射和6例双侧喷射。与显示泌尿系统异常的患者相比，尿路造影正常的患者中输尿管喷射几乎是其三倍。阳性喷射征（通常为单侧）的发生率因所采用的检查技术而异，但在常规IVP中最高发生率似乎约为30%。虽然不常见，但可能会发生明显的同侧膀胱输尿管反流（VUR）。这一事实以及报告的双侧喷射发生率较低限制了将单侧喷射用作无明显VUR指标的价值。在泌尿放射学检查中进行排尿膀胱尿道造影（MCU）的必要性仍然没有受到质疑。
