目的 探讨彩色多普勒在输尿管结石伴肾盂积水治疗中的临床应用价值。方法 检测 42只输尿管结石伴肾盂积水采用输尿管切开取石术前的肾内血流动力学指标 ,并与术后 1 5d、1月、3月检测的肾内血流动力学指标相比较 ,观察其变化情况并与术后肾功能恢复情况相联系 ,了解其相关性。结果 36只输尿管结石伴肾盂轻中度积水肾内血管彩色血流信号欠丰富 ,主肾动脉峰值流速 (Vmax)和肾脏血流量 (CO)明显低于对侧正常组 (P <0 0 5) ,RI值两者无显著性差异 (P >0 0 5)。 6只输尿管结石伴肾盂重度积水肾内血管彩色血流信号显示稀疏或缺乏 ,Vmax和CO也明显低于对侧正常 ,但RI值升高 ,与对侧正常比较差异显著 (P<0 0 5)。手术后肾内彩色血流信号、Vmax和CO与术前比较有明显改善 (P <0 0 5) ,重度积水者其RI值恢复至正常范畴。结论 彩色多普勒在手术前即能判断患侧肾功能 ,能够较为准确地预测手术后肾功能恢复的状况
Objective To investigate the clinical value of color Doppler in the treatment of ureteral calculi associated with hydronephrosis. Methods Forty-two ureteral calculi with hydronephrosis and ureterolithotomy were enrolled in this study. Intrarenal hemodynamic parameters were detected and compared with those measured at 15 days, 1 month and 3 months after operation. Observe the changes and correlate with the postoperative recovery of renal function to understand their correlation. Results Thirty-six ureteral calculi with mild or moderate hydronephrosis showed a low abundance of color flow signals in the renal vessels. The Vmax and CO in the renal arteries were significantly lower than those in the contralateral normal controls (P <0.05 ), There was no significant difference between RI values (P> 0.05). 6 ureteral calculi with renal pelvis hydronephrosis showed sparse or lack of color flow signals, Vmax and CO were also significantly lower than the normal contralateral, but RI value increased significantly compared with the contralateral normal (P <0 0 5). Renal color flow signals after surgery, Vmax and CO were significantly improved compared with preoperative (P <0 05), severe hydrocephalus RI values returned to normal. Conclusions Color Doppler can judge the ipsilateral renal function before surgery and predict the recovery of postoperative renal function more accurately
