Objective To evaluate the clinical efficacy of Memotherm TM stent,a type of metallic stent in the management of secondary ureteropelvic junction obstruction. Methods From October 1995 to June 2001,13 cases (10 males and 3 females,mean age of 41 years) of secondary ureteropelvic junction obstruction underwent the Memotherm TM stenting.They were all followed up for an average of 26 months by B ultrasound,IVU,radionuclide renography and ureteroscopy. Results Of the 13 case,8 were cured,and 3 achieved improvement,while 2 cases failed.The main complications of endoprosthetic fibrotic stricture occurred in 5 cases.The forceps or YAG laser through ureteroscopy was used to remove the endoprosthetic fibrotic tissues. Conclusions Memotherm TM stent is mostly effective in the treatment of patients with secondary ureteropelvic junction obstruction,especially for patients who has undergone multiple operations or those are ineligible for open surgery.This procedure can significantly reduce the recurrence of ureterostenosis.

Objective To summarize the causes of failed drainage of double J ureteral stents following ureteroscopy. Methods From June 2000 to March 2003,the double J ureteral stents were placed for 3972 patients (2184 males and 1788 females)following ureteroscopy.The stents were placed through retrograde approach in 3138 cases,through antegrade approach in 1497 cases.The patients were followed up until the ureteral stents were retrieved. Results Of the 4635 cases,failed drainage of double J ureteral stent was found in 115 cases (2.48%).The main causes were severe extra luminal obstruction,serious steinstrasse,severe ureteral stricture and overperiod placement of ureteral stents. Conclusions Correctly identifying the indications for ureteroscopy and the placement of double J ureteral stents as well as close follow up are the keys to reduce the failure rate of drainage of double J ureteral stents following ureteroscopy.
7.Study of space distribution law of death cases of hemorrhagic fever with renal syndrome in Kaijiang county,Dazhou city, Sichuan province
Chinese Journal of Endemiology 2013;(2):205-207
Objective To study the space distribution probability model of death cases of hemorrhagic fever with renal syndrome,so as to provide basic information for hemorrhagic fever with renal syndrome prevention and control policy making.Methods Poisson distribution and negative binomial distribution were used to fit the hemorrhagic fever with renal syndrome deaths spatial distribution in Kaijiang county,Dazhou city,Sichuan province between 1979-2010.Results The actual distribution of death cases of hemorrhagic fever with renal syndrome in Kaijiang county was not Poisson distribution (x2 =40.64,P < 0.01),but subjected to the negative binomial distribution(x2 =1.86,P > 0.50).Conclusions The space distribution of death cases of HFRS in Kaijiang county is not random,but has strict regional aggregation,which may be related to the local medical conditions,patient' s lack of knowledge about health care and other factors.
