Objective To investigate the clinical effect, influencing factors of 1 280 patients with ureteral calculi undergoing ESWL.Methods The data of 1 280 patients with ureteral calculi treated by ESWL for the first time in our hospital were retrospectively studied.There were 962 males and 318 females,age 23~78 years old,average 45.7 years old.Stones were located in the left ureter in 810 cases and right ureter in 470 cases.All patients were treated with ESWL for the first time.The lithotripsy rate, stone free rate, influencing factors and the incidence of complications after ESWL were compared over follow up period of there months.Results The overall successful fragmentation rate for all levels of stone in single session achieved 97.6%(1 249/1 280).The failure rate was 2.4%(31/1 280).Conclusion ESWL is indicated as a first choice in the treatment for patients with ureteral stones.The concrete impacted in ureteral mucosa is the key cause of failure to ESWl in ureteric stone.Once the fragments has not been cleared after ESWL, it suggests that other therapy modality should be selected.

Objective To evaluate the efficacy and safety of the pneumatic lithotripsy through ureteroscope for the treatment of ureteral calculi.Methods A total of 920 patients underwent ureteroscopic lithotripsy using pneu-matic lithotripsy 259 upper,375 middle,and 286 lower ureteral stone were treated.Results The overall successful fragmentation rate for all levels of ureteral stones in a single session achieved 94.0% (864 /920),failure rate 6.0%(56 /920).28 cases failed because of ureteral stricture.24 cases of stone moved up into the kidney.All worst -cases were in dewelled shock wave lithotripsy ESWL.Conclusion Ureteroscopic lithotripsy using pneumatic lithotripsy is a highly effective,minimally invasive and safe therapy for ureteral calculi.It is indicated as a first choice for treatment patients with ureteral stones,especially for the ones with the middle and lower uneteral stones.Develop particularly suitable for basic hospital.

Objective: To assess dietary and urinary risk factors for urolithiasis by a case-control study. Methods: A retrospective analysis was made on the pathogenic factors of 1 151 patients with urolithiasis admitted to the People′s Hospital of Chenghai District from January 2016 to June 2018, and including external environmental factors and internal personal factors. Results: The proportion of male and female patients was 1.69∶1, and the peak age at onset of disease ranged from 21 to 60 years.Most of patients were diagnosed as upper urinary tract calculi.The following variables were found to have significant effects on the morbidity of urinay calculi: less intake of water, over intake of protein, fat and salt. Conclusion The diet and increase water intake and with low-protein, low-fat and low-salt diet are helpful to prevent urolithiasis.
