To evaluate the changes of peak systolic velocity(PSV), end-diastolic velocity(EDV), and resistive index(RI) of renal and arcuate arteries at the ipsilateral and contralateral kidneys during the retrograde intrarenal surgery.
The patients who had RIRS for the treatment of renal stones were prospectively included in the study. An experienced radiologist performed doppler ultrasonography of the ipsilateral and contralateral kidney before the surgery just after the anesthesia and at the end of the surgery before stenting. The PSV, EDV, and RI of renal and arcuate arteries at the ipsilateral and contralateral kidneys were measured.
A total of 53 patients were included in the study. The postoperative mean PSV, EDV, and RI of renal arteries at the ipsilateral and contralateral arteries were similar to preoperative values. The mean PSV and RI of the arcuate arteries at the ipsilateral kidney significantly increased postoperatively (P = 0.032, P = 0.012) The postoperative mean PSV, EDV, and RI of arcuate arteries did not change significantly during the surgery. The age, gender, and flexible ureteroscopy time did not affect the change of renal and arcuate arterial PSV, EDV, and RI at the ipsilateral and contralateral kidneys.
The elevation of intrarenal pressure during RIRS did not change the blood flow at the major arteries of the ipsilateral and contralateral kidneys. On the other hand, there was a significant increase at the RI of the arcuate arteries in the ipsilateral kidney which was proposed to be related to the vasoconstriction of minor vasculature of the kidney.
评估逆行性肾内手术期间患侧和对侧肾脏肾动脉及弓形动脉的收缩期峰值流速（PSV）、舒张末期流速（EDV）和阻力指数（RI）的变化。
前瞻性纳入因肾结石接受逆行性肾内手术（RIRS）治疗的患者。一名经验丰富的放射科医生在麻醉后手术前以及手术结束支架置入前对患侧和对侧肾脏进行多普勒超声检查。测量患侧和对侧肾脏肾动脉及弓形动脉的PSV、EDV和RI。
本研究共纳入53例患者。患侧和对侧动脉术后肾动脉的平均PSV、EDV和RI与术前值相似。患侧肾脏弓形动脉的平均PSV和RI术后显著升高（P = 0.032，P = 0.012）。手术期间弓形动脉的术后平均PSV、EDV和RI无显著变化。年龄、性别和软性输尿管镜检查时间不影响患侧和对侧肾脏肾动脉及弓形动脉PSV、EDV和RI的变化。
RIRS期间肾内压力升高并未改变患侧和对侧肾脏主要动脉的血流。另一方面，患侧肾脏弓形动脉的RI显著增加，这可能与肾脏小血管的血管收缩有关。
