目的：观察比较不同条件下上尿路结石术后双 J 管后形成管壳结石的发生率，进一步了解双J 管壳结石形成的危险因素，指导预防术后结石形成。方法分组统计不同留置时间、尿酸碱值、感染指标下双 J 管壳结石的发生率，利用红外光谱法对我院560例留置双 J 管的尿结石行结石成分分析，统计双J 管壳形成结石的尿石成分比例。结果138例双 J 管留置1个月内，出现14例，占10．1％；258例留置1个月到3个月，出现31例，占12％；102例留置3个月到半年，出现32例，占31％；62例留置半年以上，出现26例，占41．9％。含草酸钙成分的有432例，发生管壳结石56例，占13．0％；含尿酸成分的有89例，发生管壳结石56例，占62．9％。 PH＜6．5、尿白细胞升高的双 J 管壳结石发生率高。结论双 J 管停留时间过长、酸性环境、合并泌尿系感染是双J 管壳结石形成的危险因素，缩短留管时间、碱化尿液可能是预防双 J 管表面结石形成的一种有效的预防方法。

Objective To investigate the elements of stone encrustation on double-J stent in patients underwent upper urinary tract surgery and the risk factors of stone formation postoperatively. Methods 560 patient with double T stent were included in the study..The incidence of stone formation on double J tube shell in different indwelling time,.urine pH,.urine infection were investigated..The ingredient of urinary calculus was analyzed by infra-red sepectrometry. Results In 138 cases indwelling double J tube within one month, there were 14 cases with stone encrustation, accounting for 10.1%. In 258 cases indwelling double J tube for one month to three months , there were 31 cases with stone encrustation,.accounting for 12.0%..In 102 cases indwelling double J tube for three months to six months , there were 32 cases with stone encrustation , accounting for 31%. In 62 cases indwelling more than half a year, there were 26 cases with stone encrustation, accounting for 41.9%. Of 432 cases with calcium oxalate , 56 cases were found stone encrustation , accounted for 13%. Of 89 cases with uric acid component, 56 cases were found stone encrustation, accounted for 62.9%. Those cases with the urine PH less than 6.5, and with urine infection, had a higher incidence of stone encrustation on double J stent. Conclusion Longer residence time of double J tube, acidic environment, combined with urinary system infection are the risk factor for stone encrustation in patients underwent operation of upper urinary tract. Shortening the indwelling time , alkalizing the urine can prevent stone formation.
