To determine whether incorrect placement of an indwelling stent plays any role in the causation of irritative voiding symptoms and loin pain.
Sixty patients with ureteral calculous disease were prospectively requested to analyze the symptoms that they encountered 1 week after stent insertion via a questionnaire handed out at their discharge from the hospital. The answers were analyzed with reference to the intravenous urogram performed at presentation and the plain radiograph taken immediately after stent insertion.
Stents crossing the midline in the bladder and having incomplete loops at the lower end give rise to higher morbidity.
The present series suggests that the position and completeness of the lower loop do influence symptom severity. Proper attention to detail whilst placing a stent should help reduce the incidence and severity of stent-related symptoms.
确定留置支架位置不当是否在刺激性排尿症状和腰痛的病因中起任何作用。
前瞻性地要求60例输尿管结石病患者，通过出院时发放的问卷分析支架置入1周后所遇到的症状。参考就诊时进行的静脉肾盂造影和支架置入后立即拍摄的平片对答案进行分析。
支架在膀胱内穿过中线且下端环圈不完整会导致更高的发病率。
本系列研究表明，下端环圈的位置和完整性确实会影响症状严重程度。放置支架时适当注意细节应有助于降低与支架相关症状的发生率和严重程度。
