PurposeTo evaluate the clinical factors that impact ureteral stent-related lower urinary tract symptoms (LUTS) after ureteroscopic ureterolithotomy, including the stent position and medication.
Materials and MethodsFifty-three patients who underwent ureteroscopic ureterolithotomy with indwelling a stent were distributed into three groups. On demand analgesics were given to the group 1 (n=18). Daily tamsulosin 0.2 mg was added for group 2 (n=15) and daily tamsulosin 0.2 mg and tolterodine 4 mg was added for group 3 (n=20). The patients were also subclassified into appropriate or inappropriate group according to stent position. All the patients completed a visual analogue scale (VAS) and International Prostate Symptom Score (IPSS) on the 1st and 7th postoperative days. The VAS and IPSS were analyzed according to the medication groups and the stent position.
ResultsIn the appropriate stent potion group, only the storage symptom scores of groups 2 and 3 on the 1st postoperative day were significantly lower than those of the group 1 (p=0.001). This medication effect on LUTS was not observed in the inappropriate stent position group. In this group, total IPSS (p=0.015) and storage symptom scores (p=0.002) were higher than in the appropriate stent position group on the 7th postoperative day.
ConclusionsCorrect placement of the stent was more important than medication for lessening stent-related storage symptoms.
