Analysis Of Influential Factors Of Extracorporeal Shock Wave Lithotripsy In Treatment Of Urinary Calculi

Objective:To explore the factors influencing the effect of ESWL in the treatment of urinary calculi,and providing reference for clinical practice.Methods:Selection of our hospital lithotripsy from January 2011 to October 2016 Application Baiyun Mountain BYS liquid B-type positioning in vitro shock wave lithotripsy and Siemens MODULARIS Variostar electromagnetic double positioning extracorporeal shock wave crushing machine extracorporeal shock wave gravel ESLL)treated 4101 cases of urinary tract stones,a total of 4101 cases,including 2740 cases of male and female 1361 cases,aged 9 to 84 years,mean 43.05 ± 13.13 years,of which 745 cases of kidney stones,3180 cases of ureteral calculi,bladder stones 176 cases.Absolute contraindications to the exclusion of extracorporeal shock wave gravel are: distal obstruction of stones,hemorrhagic disease,severe cardiovascular and cerebrovascular diseases,pregnancy,obesity can't focus or because of severe bone,joint deformity affect the position,placement of pacemakers and so on.This study also excluded the ureteral stenosis,renal nonfunction,renal congenital dysplasia and other special circumstances into the extracorporeal shock wave gravel taboo.All patients in this group were diagnosed by B-ultrasonography,KUB / IVU,or CT,and the data were completed before operation,postoperative and postoperative follow-up.The treatment results were evaluated after 3 months follow-up.Stones completely discharged or residual stone ?3mm and accompanied by hydronephrosis as a successful treatment,stones did not discharge or residual stone> 3mm and hydronephrosis without reduction or aggravating treatment failure.The factors influencing the effect of extracorporeal shock wave lithotripsy on urinary calculi were analyzed by statistical method.Results:All patients who underwent ESWL treatment were followed up for 3 months.The success rate was 83.3%,the rate of stone(rate of success)was 82.98%;698 cases of stone failure and residual failure(treatment failure)were 17.02% Stones can't be crushed without row of 595 cases(85.24%),after the debris can't be completely discharged 103 cases(14.76%).All patients receiving ESWL in 6 patients after renal subcapsular hematoma,after conservative treatment half a year review CT,hematoma disappeared.According to the treatment effect,the patients were divided into two groups,the stones were completely discharged or the residual stone ? 3mm for the successful group,the stones were not discharged or the residual stone> 3mm for the failure group,the application(statistical method)?~2 test two data.Conclusion:The results showed that the types of crusher,the age of the patients,the body mass index(BMI),the location of the stones,the distance from the stone distance(SSD),the way of positioning and the way of the shock wave,the frequency of the shock wave and the energy Way is an important factor affecting the therapeutic effect of ESWL.Patients in the line before the treatment of ESWL,select the appropriate gravel models,a comprehensive assessment of the indicators,the correct mode of operation,for the treatment effect has a very important guiding significance.
