【摘要】：目的探讨输尿管双J支架管置入术后再次梗阻的影响因素。方法回顾性分析121例肿瘤性肾盂积水置入输尿管双J管的临床资料,对肿瘤进展、尿盐结垢、肾小球滤过功能、每日尿量、尿路感染、留管时间、下尿路功能及双J管内径等因素总结,分析输尿管再次梗阻的原因及预防方法。结果 121例患者48例再梗阻,其中肿瘤进展、尿盐结垢、尿路感染、留置时间是主要影响因素,占87.5%;肾小球滤过功能、每日尿量及下尿路功能也是重要因素,占12.5%。另外,双J管内径也是影响再梗阻的因素。通过局部控制肿瘤、改善饮用水及按时换双J管等相应措施,44例未再梗阻,4例因肿瘤进展再梗阻改外引流。结论输尿管双J管置入后,积极抗肿瘤治疗、降低饮用水硬度、改善肾功能、多饮水排尿、预防尿路感染、缩短留管时间、纠正下尿路功能障碍能有效地延缓或预防双J管再次梗阻。
[Abstract]:Objective to investigate the influencing factors of re-obstruction after ureter double J stent implantation. Methods the clinical data of 121 cases of malignant hydronephrosis inserted into double J tube of ureter were analyzed retrospectively. the factors such as tumor progress, urinary salt scaling, renal filtration function, daily urine volume, urinary tract infection, retention time, lower urinary tract function and double J tube diameter were summarized. The causes and prevention methods of reobstruction of ureter were analyzed. Results there were 48 cases of re-obstruction in 121 patients, in which tumor progress, urinary salt scaling, urinary tract infection and indwelling time were the main influencing factors, accounting for 8.5%, and renal filtration function, daily urine volume and lower urinary tract function were also important factors (12.5%). In addition, the inner diameter of double J tube is also the factor affecting re-obstruction. By controlling the tumor locally, improving drinking water and changing double J tube on time, 44 cases were not obstructed again and 4 cases were changed to external drainage because of tumor progress. Conclusion active anti-tumor therapy, reduction of hardness of drinking water, improvement of renal function, more drinking water urination, prevention of urinary tract infection, shortening of indwelling time and correction of lower urinary tract dysfunction can effectively delay or prevent re-obstruction of double J tube after double J tube implantation.
