Objective To summarize the impact factors of extracorporeal shock wave lithotripsy (ESWL) in ureteral calculi patients.Methods The data of 287 patients with ureteral calculi from January 2010 to December 2012 in the Aerospace General Hospital of Beijing who received the ESWL were retrospectively analyzed.The relationship between ESWL' s effect and patients' gender, age, the stone' s size, the stone's location, the length of the course and the stone bed' s polyps hyperplasia was analyzed.Results The Partial correlation course and chi-square test showed that, there was statistically significant difference between the ESWL treatment effect and patient' s age, patient' s length of the disease course and patient' s stone size (P＜0.01).The value of OR between patient' s age and ESWL treatment effect was 1.905, showed that with the age of the patients increased every 10 years, the success rate of ESWL was reduced by 1.905 times.The value of OR between the patient' s length of the disease course and ESWL treatment effect was 2.809,indicated that with the duration of the course of prolonged every 1 month, the ESWL success rate decreased by 2.809 times.The value of OR between stone size and ESWL effect was 2.277, showed that the ratio between the stone diameter of 1.1-2.0 cm and 0.6-1.0 cm, the ESWL success rate reduced by 2.277 times.For the surgery patients who were failure to ESWL treatment,we found that there has statistical significance between the patients' length of disease course and stone bed' s polyps hyperplasia(P＜0.01), but the relationship between the stone bed' s polyps hyperplasia and the gender, the age, the stone' s position, the stone ' s size had no statistical significance (P ＞ 0.05) .Conclusion The patient ' s age, the length of the disease course, the stone ' s size and stone' s position are significantly affect to the effect of ESWL.There have closely relationship between the length of the disease course and the stone bed' s polyps hyperplasia, which is the reason why the longer length of the course, the worse the ESWL' s effect.This has very important instructed meaning for anticipating the treatment effect by the comprehensive evaluation of the patients before ESWL treatment.

Objective To observe the clinical effects of laparoscopic varicocelectomy to ejaculum quality in patients with varicocele.Methods Fifty patients with varicocele were treated by laparoscopic varicocelectomy.The patients were grouped into Group A and Group B according to venous diameter.Semen parameters including semen volume,sperm density,sperm motilities (a + b + c),sperm motilities (a + b),sperm motilities (a),total sperms,normal spermmorphology rate and sperm survival rate were measured and recorded before operation and 1,3,6 months after operation.Results After the follow-up of 6 months above in 50 cases,there is no significant difference about semen volume preoperative and postoperative at different follow-up time(P ＞ 0.05).In some semen parameters(sperm density,sperm motilities,total sperms,normal spermmorphology rate),there is no significant difference between preoperative and postoperative 1 month(P ＞ 0.05),but there is significant difference between postoperative 3 months and postoperative 6 months(P ＜ 0.05).There is no significant difference in preoperative semen parameters between the 2 groups(P ＞ 0.05),but there is significant difference in postoperative 6 month(P ＜0.05).In Group A,there is significant difference in sperm density between preoperative and postoperative 1 month (P ＜0.05).In Group B,there is significant difference in sperm density,sperm motilities and normal spermmorphology rate between preoperative and postoperative 1 month(P ＜ 0.05).Conclusions Laparoscopic varicocelectomy has a positive effect on sperm parameters,it can significantly improve postoperative semen parameters.Semen parameters improve to a relatively stable level by 3 months following operation.
