Introduction: Causes of pain after ureteral stent removal are poorly understood. Stent duration may be a factor. We studied the relationship between pain after ureteral stent removal and patient and procedural factors.
Methods: A survey to assess the relationship between quality of life and subsequent treatment decisions was randomly distributed to patients greater than or equal to 18 years of age and with a history of a ureteral stent in seven medical centers across the U.S. participating in an endourology research collaborative between July 2016 and June 2018. Statistical analyses were performed using Chi-square and multiple logistic regression.
Results: A total of 327 completed surveys were analyzed. Twenty seven percent of patients reported increased pain in the hours after ureteral stent removal. Patients with a stent 7 days or less were significantly more likely to experience pain after stent removal compared to those with a stent more than 7 days (33.3% vs. 22.8%, p=0.04). After adjusting for age, gender, and health status, patients with a stent more than one week were significantly less likely to report pain in the hours after stent removal (OR: 0.59, 95% CI: 0.35-0.99). Female gender (OR: 2.41, 95% CI: 1.42-4.10) was associated with increased pain after stent removal, while increasing age was inversely associated (OR: 0.52, 95% CI: 0.36-0.74).
Conclusions: Approximately, one in four patients will experience increased pain after ureteral stent removal. Patients with a ureteral stent in place 7 days or less and who are younger may be more likely to experience an increase in pain in the hours after stent removal. Understanding factors associated with post-stent removal pain could be helpful in appropriately counseling and managing patients at high risk for morbidity after stent removal.
