Factors associated with unplanned clinical encounters for ureteral stent-related symptoms.

Abstract

Ureteral stent-related symptoms (USRS) often result in unplanned phone calls and ER visits. We hypothesize that patient factors can be identified to predict these unplanned encounters. Retrospective analysis of indwelling ureteral stent placements from 2014 to 2019 at a single institution by CPT code was performed. Patient demographics, discharge medications, and clinical factors were evaluated using multiple logistic regression with respect to postoperative telephone and emergency room (ER) encounters for USRS. Of 374 patients, 75 (20.1%) had one or more encounters for USRS: 48 (12.8%) called the clinic and 39 (10.4%) returned to the ER. Chronic opioid use was predictive of calls to clinic and ER visits (OR 3.21 [CI 1.42-6.97], p < 0.01 and OR 3.64 [CI 1.45-8.98], p < 0.01). Survival analysis stratified by history of chronic opioid use and discharge opioid prescriptions demonstrated that opioid naïve patients receiving opioids at discharge had unplanned encounters sooner and more often [Calls p = 0.025, ER p = 0.041]), whereas patients with chronic opioid usereturned to the ER sooner and more frequently when prescribed additional opioids (Calls p = 0.4, ER p = 0.002). Patients with a history of chronic opioid use may experience more intense USRS or have a lower threshold to seek medical care than opioid naïve patients and tend to bypass calling the clinic for the ER. Given that none of the studied medications reduced unplanned patient contact for USRS, urologists should consider upfront definitive management of urinary obstruction when appropriate.
