Abstract
Abstract
Background/Purpose: Whether the length of stent affects stent-related symptoms after urological procedures remains controversial. We aimed to evaluate the predictive factors for stent-related urinary tract symptoms after uncomplicated ureteroscopy.
Methods: We prospectively assessed a total of 50 patients who underwent double -j- stent and 6-Fr double-J ureteral stent placement. the demographic and perioperative data and stent characteristics, including the length (26 or 28cm), position of proximal end (upper calyx or pelvis), position of distal end (crossing midline or not), and configurations of both ends (complete or incomplete curl) were recorded. All patients completed a ureteral stent symptoms questionnaire to evaluate the double -j- stent-related urinary symptoms and pain 1 week and 1 month after the procedure. All variables were analyzed to assess the symptoms and their severity and to determine the factors that were significantly associated with stent-related symptoms.
Results: Twenty-three (46%) male and 27 (54%) female patients were enrolled in this study. In multivariate analysis, we found that percentage of patients with urge incontinence increased significantly after 1 month in comparison with first week after double -j- placement and the length of stent (28cm) aggravated the urgency, urge incontinence and dysuria and we noted that patients with position of proximal end of the stent in renal pelvis had significantly urgency. Crossing the midline of the distal end was significantly associated with urge incontinence.
Conclusion: The length of stent and crossing the midline of the distal end were significantly associated with stent-related symptoms after URS. selection of the proper length of double-J stent is the most important factor in minimizing stent-related symptoms.
