Talwar R, Dobbs RW, Stambiako H, et al. - Researchers sought to attain further insight into the degree and time to resolution of pain in the post-operative period via capturing patient-reported pain intensity and interference prospectively in patients following ureteroscopy for nephrolithiasis. They included patients undergoing ureteroscopy for renal/ureteral stones who all received non-opioid postoperative pain control. PROMIS-Pain Intensity and PROMIS-Pain Interference instruments were prospectively completed by participants preoperatively on POD 0 and via email on POD 1, 7, and 14. Analysis revealed immediate elevation of pain intensity and interference, but by POD 7, intensity normalizes, while interference remains raised until POD 14. Intensity and interference were both influenced by age and indwelling ureteral stent. Lower intensity and interference at POD 1 were evident with increasing age. Higher intensity and interference were noted at POD 7 in the presence of a postoperative stent.
