Objective To compare the clinical effects of two different methods in the treatment of colic caused by ureteral calculi. Methods 120 patients with acute renal colic caused by ureteral calculi were divided into two groups. The experimental group used ESWL for analgesia, while the control group used Demerol for analgesia. To evaluate two different analgesic methods. Results The analgesic effect of ESWL in the treatment of acute renal colic caused by ureteral calculi was significantly better than that of the control group. Conclusion ESWL has a rapid analgesic effect on acute renal colic caused by ureteral calculi, and achieves the therapeutic purpose.
Clinical analysis of ESWL in the treatment of drug-induced acute colic
In order to effectively relieve and treat the pain of acute renal colic in patients with ureteral calculi, our department used HK-ESWL-VI-865 water bladder lithotriptor to perform extracorporeal shock wave lithotripsy on patients with acute colic, which greatly alleviated the pain of patients, with obvious analgesic effect, short pain time and obvious better curative effect than clinical routine drugs. The report is as follows.
1 objects and methods
1. 1 General data From June 2004 to June 2006, 120 patients with acute renal colic caused by ureteral calculi were randomly divided into ESWL experimental group and dolantin control group, all of which met the typical diagnosis of acute renal colic caused by ureteral calculi, and the stones were single. Location of stones: 72 cases in the upper ureter, 9 cases in the middle and lower ureter and 39 cases in the lower ureter (including the end of ureter), aged from 23 to 68 years, including 82 males and 38 females. There were 39 males and 265,438 0 females in ESWL experimental group, and 43 males and 65,438 0 females in drug treatment control group. There was no significant difference in sex, age and stone site between the two groups.
1.2 method
1.2. 1 ESWL In the experimental group, HK-ESWL-VI-865 water bladder lithotriptor was used in our department, and X-ray and B-ultrasound were used according to the patient's condition (B-ultrasound completely located upper ureteral calculi). Upper ureteral calculi lie in supine position, and lower ureteral calculi lie in prone position. During operation, the impulse voltage is 10. The impact frequency is 1500 ~ 3000 times, and the impact frequency is 60 ~ 70 times/min. Two patients experienced nausea and vomiting during the operation. After intramuscular injection of 4 ml of Amal, the treatment was completed.
1.2.2 drug control group: 75 ~ 100 mg of dolantin was injected intramuscularly in our department, and those who had no obvious analgesic effect after injection were injected again with ureteral dilator. The main component of pethidine hydrochloride is pethidine hydrochloride, which is the most commonly used synthetic powerful analgesic. This product is an agonist of μ and K receptors in the central nervous system, and has analgesic and sedative effects. After intramuscular injection 10min, it has analgesic effect and lasts for 2 ~ 4 hours. It is a commonly used analgesic in clinic. Both groups were given a certain amount of anti-inflammatory drugs to control and prevent urinary system infection.
Evaluation method of 1.3 The patients in the two groups started timing after each method was used to treat colic caused by ureteral calculi, and the pain relief of patients was fed back at 30min, 2h and 24h respectively, with painless as the count.
1.4 statistical methods χ2 test was used for data analysis.
Two results
See table 1. This study found that the ESWL experimental group was significantly better than the drug control group in relieving acute colic caused by ureteral calculi, and the difference was very significant.

3 discussion
Obviously, the rapid analgesic effect of ESWL in the treatment of acute colic caused by ureteral calculi is obviously better than that of Demerol. ESWL gradually smashes stones into particles that can be naturally discharged by means of shock waves generated by repeated discharges [1], which reduces the stimulation of stones on ureteral smooth muscle and achieves the purpose of relieving pain. More importantly, ESWL can not only relieve the acute attack of renal colic caused by ureteral calculi, so that it can quickly relieve pain, but also discharge stones in a short time, greatly reducing the incarceration time and inflammation of stones in the ureter, which can not only relieve pain but also achieve the purpose of treatment. Demerol is a stimulant of the central nervous system, which can improve the tension of ureteral smooth muscle, but it can not reduce the stimulation of calculus on ureteral smooth muscle, and relieve colic slowly and in a short time, which can not achieve the purpose of treating calculus. Therefore, we believe that ESWL treatment is the first choice once ureteral calculi cause acute renal colic.
