Symptoms after removal of ureteral stents
BACKGROUND AND PURPOSE: Urology practices frequently encounter individuals who experience various degrees of pain/discomfort after ureteral stent removal. These symptoms have been previously proved to greatly affect functionality, convalescence time, quality of life, and healthcare costs. The etiology is unclear, but the condition is often self-limiting. We counsel individuals on their risk of having post-ureteral stent removal pain based on anecdotal data. We sought to evaluate the incidence of post-ureteral stent removal pain and attempt to find the probable cause. PATIENTS AND METHODS: All individuals who had a ureteral stent placed and subsequently removed for various etiologies (between January 2012 and May 2013) were evaluated by filling a survey conducted by a member of the healthcare team 1 to 3 weeks after ureteral stent removal. Univariate and multivariate analysis were used to assess correlation between demographics, operative procedures, convalescent time, and post-ureteral stent removal symptoms. All statistical analyses were performed using SAS((R)) software, and a P value of less than 0.05 was considered to indicate statistical significance. RESULTS: Of the 104 individuals in the final cohort, 64% had symptoms after stent removal (pain, hematuria, frequency, urgency, or fever), and among those with symptoms, 60% experienced pain/discomfort. On univariate analysis, stone basketing and indwelling stent discomfort correlated positively with pain after stent removal. On the other hand, the use of anticholinergics and a longer indwelling stent duration were associated with less pain after stent removal. On multivariate analysis, correlation with procedures involving basket extraction and indwelling stent discomfort maintained significance. CONCLUSION: Our series suggests that two of three individuals who undergo ureteral stent removal experience symptoms thereafter. Individuals undergoing stone basket extraction and those who experienced stent discomfort were more likely to have pain after stent removal. Anticholinergic use and stents indwelling for a longer time were associated with less pain after stent removal.
