Introduction: 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 is often self limiting. We counsel patients on their risk of having post ureteral stent removal pain based on anecdotal data. Herein, we sought to evaluate the incidence of post ureteral stent removal pain and attempt to find the probable cause. Methods: All the individuals who had a ureteral stent placed and subsequently removed for various etiologies (between Jan'12 & May'13) 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 SASĀ® 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 anti-cholinergics 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 2 out of 3 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 duration of time were associated with less pain after stent removal.
