为了恢复输尿管的运动和排出力而电刺激上尿路是治疗输尿管结石病人的方法之一。但是间接电刺激至今还不能在机体深部组织成功地建立足够的电流密度,而且上尿路的神经肌肉组织的特点是对电流刺激作用极不敏感。本文作者将电极直接安置到肾盂而行直接电刺激,这种方法创伤很小。静注X线造影剂行排泄性尿路造影,用X线电视屏监视上尿路情况。用普通X片和或电视磁带录像作资料记录。借助膀胱镜将双接头电极放入输尿管,该电极直径相当于4号或5号输尿管导管。刺激电极放在肾盂,记录电极低于刺激电极15cm。用柔韧、弹性好的导管就容易将电极放到结石上方。在病人腰部皮肤上将外刺激电极固定到面积为8×12cm的不阻档X线的导电碳质网。为描
One of the ways to treat ureteral calculi is to electrically stimulate the upper urinary tract in order to restore ureteral movement and discharge. However, indirect electrical stimulation has so far not been able to successfully establish sufficient current density in the deep body tissues, and neuromuscular characteristics of the upper urinary tract are extremely insensitive to current stimulation. The authors placed the electrode directly to the renal pelvis and direct electrical stimulation, this method trauma is very small. Intravenous X-ray contrast agent excretion urography, X-ray TV screen to monitor the situation on the urinary tract. With ordinary X-ray or video tapes for data records. A cystoscope is used to place the double-ended electrode in the ureter, which is equivalent to a No. 4 or No. 5 ureteral catheter. Stimulation electrodes were placed in the renal pelvis and the recording electrodes were 15 cm below the stimulation electrodes. With a flexible, flexible catheter it is easy to place the electrode over the stones. External stimulation electrodes were fixed on the patient’s lumbar skin to an electrically conductive carbonaceous mesh of 8 × 12 cm non-blocking X-ray. For the description
