To evaluate the accuracy of Color Doppler ultrasonography for diagnosing post pyeloplasty elimination of obstruction in Ureteropelvic Junction Obstruction patients.
Patients with the diagnosis of UPJO enrolled in the study and underwent open pyeloplasty. Three to 6 months after the operation, patients were recalled and underwent isotope scan as the gold standard test and renal color Doppler ultrasonography to assess the success rate of pyeloplasty.
A total of 39 patients were evaluated and analyzed. The average follow-up time for patients was 9.1 months. The success rate of surgery in the study population was 100%. The mean RI of the affected side before the operation was 0.69 ± 0.01 and after the pyeloplasty, it reached to 0.65 ± 0.01. The difference between the mean RI of the affected side before and after the operation is 0.04 (P < 0.001). Age, type and severity of obstruction and the technique of surgery did not have any impact on these parameters. The difference between the RI of the affected and healthy side was termed ΔRI. ΔRI before and after the operation was 0.084 and 0.014, respectively. The decrease of ΔRI in the case of pyeloplasty is 0.07 on average (P < 0.001), which can be predicted for pyeloplasty success.
Color Doppler ultrasonography can be used as a non-invasive, fast, non-expensive, and available modality for evaluating the outcome of pyeloplasty instead of the nuclear scan or IVP.
评估彩色多普勒超声检查在诊断肾盂成形术后输尿管肾盂连接部梗阻患者梗阻解除情况的准确性。
诊断为输尿管肾盂连接部梗阻的患者纳入本研究并接受开放性肾盂成形术。术后3至6个月，召回患者并进行同位素扫描作为金标准检查以及肾脏彩色多普勒超声检查，以评估肾盂成形术的成功率。
共评估分析了39例患者。患者的平均随访时间为9.1个月。研究人群的手术成功率为100%。患侧术前平均阻力指数为0.69±0.01，肾盂成形术后达到0.65±0.01。患侧术前和术后平均阻力指数的差异为0.04（P<0.001）。年龄、梗阻类型和严重程度以及手术技术对这些参数没有任何影响。患侧与健侧阻力指数的差值称为ΔRI。术前和术后的ΔRI分别为0.084和0.014。肾盂成形术时ΔRI平均下降0.07（P<0.001），这可预测肾盂成形术的成功。
彩色多普勒超声检查可作为一种无创、快速、廉价且可获得的方法，用于评估肾盂成形术的结果，替代核素扫描或静脉肾盂造影。
