| 目的 观察超声测量输尿管喷尿参数用于评估保守治疗单发输尿管结石的效果。方法 前瞻性纳入129例接受保守治疗的单发输尿管结石患者,以治疗后随访1个月内CT或腹部平片未见同侧输尿管结石为成功,否则为失败;比较不同结局患者超声资料,包括结石最大径、侧别、位置、肾盂前后径及输尿管喷尿参数(频率、峰值流速及持续时间);采用多因素logistic回归分析筛选临床结局的独立影响因素;以受试者工作特征(ROC)曲线及曲线下面积(AUC)分析各参数的评估效能。结果 保守治疗87例成功(成功组)、42例失败(失败组)。多因素分析结果显示,结石最大径、输尿管喷尿频率、输尿管喷尿峰值流速及输尿管喷尿持续时间均为保守治疗单发输尿管结石成功的独立影响因素(P均＜0.05)。ROC曲线显示,输尿管喷尿频率评估效能最高,其AUC为0.858;以1.45次/分为最佳截断值,输尿管喷尿频率评估保守治疗输尿管单发结石临床结局的敏感度、特异度、阳性预测值、准确率及F1值分别为78.57%、83.91%、70.21%、82.17%及0.742。结论 超声测量输尿管喷尿参数有助于评估保守治疗输尿管单发结石效果。 |

| Objective To observe the value of ureter jet parameters measured with ultrasound for assessing effectiveness of conservative treatment of single ureteral calculus. Methods Totally 129 patients with single ureteral calculus who would undergo conservative treatment were prospectively enrolled. Taken no ipsilateral ureteral calculus showed on CT nor abdominal plain film during 1 month's follow-up after treatment as the standards of successful treatment and the otherwise as failure. Ultrasonic data, including the maximum diameter, side and location of ureteral calculi, the anteroposterior diameter of renal pelvis and ureter jet parameters, i.e. the frequency, peak velocity and duration were compared between patients with different outcomes. Multivariate logistic regression analysis was performed to screen the independent impact factors of clinical outcomes. Then receiver operating characteristic (ROC) curves were drawn, and the area under the curve (AUC) was calculated to evaluate the efficacy of the above parameters. Results Conservative treatment was successful in 87 cases (successful group) but failed in 42 cases (failure group). Multivariate analysis showed that the maximum diameter of calculus, as well as the frequency, peak velocity and duration of ureter jet were all independent impact factors of success of conservative treatment for single ureteral calculus (all P＜0.05). ROC curve demonstrated that the frequency of ureter jet had the best efficacy, with AUC of 0.858. Taken 1.45 times/min as the optimal cut-off value, the sensitivity, specificity, positive predictive value, accuracy and F1 score of the frequency of ureter jet for assessing effectiveness of conservative treatment of singke ureteral calculus was 78.57%, 83.91%, 70.21%, 82.17% and 0.742, respectively. Conclusion Ureter jet parameters measured with ultrasound was helpful for assessing effectiveness of conservative treatment of single ureteral calculus. |
