To assess whether the mild dilatation of the right ureter in women that is sometimes seen on intravenous urography (IVU) represents persistent dilatation after a previous pregnancy.
The intravenous urograms of 71 men, 63 parous and 27 nulliparous women were evaluated prospectively. The two groups of women were divided into those with and without a confirmed history of urinary tract infection (UTI) as the indication for IVU. producing five groups in all. Measurements were taken on both the 5-min and the compressed or release films on each side.
There were no significant differences in ureteric diameters among the five groups for the uncompressed right ureter (P=0.23), the left ureter uncompressed (P=0.32) or compressed (P=0.87). For the compressed right ureter, the difference was significant, with the diameters in the parous women with proven UTIs being larger than in the other groups (P=0.043).
There is a significant increase in the diameter of the compressed right ureter in the group of parous women with a history of proven UTI. Infection or parity alone do not produce this effect: the combination of the two factors is required.
评估女性静脉尿路造影（IVU）时有时可见的右侧输尿管轻度扩张是否代表既往妊娠后的持续性扩张。
前瞻性评估71名男性、63名经产妇和27名未产妇的静脉尿路造影。两组女性根据有无确诊的尿路感染（UTI）病史分为两组，UTI病史作为IVU的指征，共分为五组。在每侧的5分钟片以及压迫或松开片上进行测量。
五组之间，未受压的右侧输尿管（P = 0.23）、未受压的左侧输尿管（P = 0.32）或受压的左侧输尿管（P = 0.87）的输尿管直径无显著差异。对于受压的右侧输尿管，差异显著，有确诊UTI病史的经产妇的输尿管直径大于其他组（P = 0.043）。
有确诊UTI病史的经产妇组中，受压的右侧输尿管直径显著增加。单独的感染或产次不会产生这种影响：需要这两个因素的共同作用。
