Ureteral stents are used in various modern urologic procedures. Although forgotten double-J (JJ) stents are an infrequent problem, they are associated with significant medical problems. Encrustation from excessive indwelling time increases morbidity and may require extracorporeal shock wave lithotripsy to free the coils of the cementing calcerous material. An effective system should be in place to ensure timely removal. The previously used "card" system not only is difficult to manage but has proved unreliable. We describe a computerized program that tracks JJ stents and alerts physicians about stents that need removal.
Two hundred eighteen patients who were stented between January 1997 and December 1998 were tracked through an integrated computerized program. This program keeps a log of all patients who received a JJ stent and determines the last date by which it should be removed. Patients are reminded if they have not returned for removal of the implant 2 weeks before it is overdue.
Two hundred twenty-five JJ stents were placed in 218 patients. Comparison of data between the periods before and after computer program inception showed that the incidence of stents retained longer than their expiration time decreased from 12.5% to 1.2% in the first year of the program and 1.5% in the second year of the program.
Forgotten implants pose a significant management dilemma for physicians. Our tracking program significantly lowered the incidence of overdue JJ stents from 12.5% to 1.2% and 1.5% in the first and second years, of the program respectively (p = .00039). We propose that this technically simple program should be in place for all implants placed in patients. The problems we encountered in the smooth running of this system could be averted by incorporating several recommendations.
输尿管支架用于各种现代泌尿外科手术中。尽管遗忘双J(JJ)支架是个不常见的问题,但却会引发严重的医疗问题。留置时间过长导致的结壳会增加发病率,可能需要体外冲击波碎石术来清除钙化物质的硬结。应该建立一个有效的系统来确保及时取出支架。以前使用的“卡片”系统不仅管理困难,而且已被证明不可靠。我们描述了一个计算机程序,该程序可跟踪JJ支架并提醒医生哪些支架需要取出。
通过一个集成计算机程序对1997年1月至1998年12月期间置入支架的218例患者进行跟踪。该程序记录所有接受JJ支架的患者,并确定应取出支架的最后日期。如果患者在支架到期前2周未回来取出植入物,程序会发出提醒。
218例患者共置入225个JJ支架。计算机程序启用前后各时间段的数据比较显示,在该程序的第一年,支架留置时间超过其到期时间的发生率从12.5%降至1.2%,第二年为1.5%。
遗忘植入物给医生带来了重大的管理难题。我们的跟踪程序在该程序的第一年和第二年分别将过期JJ支架的发生率从12.5%显著降低至1.2%和1.5%(p = 0.00039)。我们建议对所有植入患者体内的植入物都应采用这个技术上简单的程序。通过纳入一些建议,可以避免我们在该系统平稳运行中遇到的问题。
