Controversy exists regarding the need for ureteral stent insertion after routine ureteroscopic stone surgery. We designed a questionnaire to assess and better understand the practice patterns of urologists for stent applications.
A 26-question survey was distributed to 570 community and academic urologists. The answers were anonymously tabulated to determine the practice patterns for stent placement.
Of the 173 respondents, 97.7% performed ureteroscopic surgery, with the majority (77%) performing 1 to 10 procedures per month. Sixty-eight percent of urologists considered more than 70% of their ureteroscopic procedures "routine." Only 21% of urologists dilated the ureteral orifice more than 90% of the time. Those who dilated the ureteral orifice used a balloon (43%), ureteral access sheath (13.5%), or both (21%). The use of an access sheath did not change stenting practices for 75% of urologists. Patterns vary with regard to length of indwelling time, with 85% of urologists maintaining the stent for fewer than 7 days. Most urologists use either cystoscopy (42%) or pull-suture in clinic (37%) to remove stents. Patient tolerance is the most significant problem with stents reported by 97.6% of urologists. The respondents were divided into three experience-based groups: group 1, <2 years of experience; group 2, 2 to 10 years; and group 3, >10 years. Using Fisher's exact test, there were no statistically significant differences between the groups.
A wide variability exists among urologists in the practice patterns of stent insertion after routine ureteroscopic surgery. Most consider their procedures routine and are more likely to place stents after ureteral dilation despite growing evidence to the contrary. Knowledge of the varied practices may aid less experienced urologists in their decision to insert a stent after ureteroscopy.
对于常规输尿管镜取石术后是否需要置入输尿管支架存在争议。我们设计了一份问卷,以评估并更好地了解泌尿外科医生在支架应用方面的实践模式。
向570名社区及学术型泌尿外科医生发放了一份包含26个问题的调查问卷。对答案进行匿名统计,以确定支架置入的实践模式。
在173名受访者中,97.7%进行过输尿管镜手术,大多数(77%)每月进行1至10例手术。68%的泌尿外科医生认为其超过70%的输尿管镜手术为“常规手术”。只有21%的泌尿外科医生在超过90%的情况下会扩张输尿管口。扩张输尿管口的医生中,使用球囊的占43%,使用输尿管通路鞘的占13.5%,两者都使用的占21%。对于75%的泌尿外科医生而言,使用通路鞘并未改变支架置入的做法。留置时间的模式各不相同,85%的泌尿外科医生将支架留置时间维持在7天以内。大多数泌尿外科医生在门诊使用膀胱镜(42%)或牵拉缝线(37%)来取出支架。97.6%的泌尿外科医生报告称,患者对支架的耐受性是最显著的问题。受访者被分为三个基于经验的组:第1组,经验不足2年;第2组,经验为2至10年;第3组,经验超过10年。使用Fisher精确检验,各组之间无统计学显著差异。
泌尿外科医生在常规输尿管镜手术后的支架置入实践模式存在很大差异。大多数医生认为他们的手术是常规手术,并且尽管越来越多的证据表明相反情况,但在输尿管扩张后更有可能置入支架。了解这些不同的做法可能有助于经验不足的泌尿外科医生在输尿管镜检查后决定是否置入支架。
