Although stents are effective, they can cause bladder spasms, pain, urinary urgency, and other uncomfortable symptoms.\n\nParticipants aged 8 to 18 years will receive both a standard Cook double-J ureteral stent and a Polaris Ultra ureteral stent during two planned procedures. The order in which the stents are used will be assigned at random, and participants and caregivers will not be told which stent is in place during each treatment period. Participants will report bladder spasms, pain, urinary symptoms, and quality of life through questionnaires and symptom assessments. The study will determine whether differences in stent design affect comfort, bladder spasms, urinary tract infections, or other stent-related complications.

Unfortunately, stents are poorly tolerated by a significant number of patients, with up to 100% complaining of bothersome pain and 10% of patients with unplanned healthcare visits. Further complicating kidney stone management is the frequency of concurrent chronic kidney disease (CKD) or acute kidney injury (AKI) that prohibits many patients from taking NSAIDs which limits pain management options. There is now a push to treat these patients with multimodal analgesia to provide better care and reduce opioid use. Suzetrigine is a new a first-in-class selective inhibitor of the NaV1.8 sodium channel that functions as a non-opioid analgesic developed to treat acute pain and neuropathic pain. This study assesses the addition of suzetrigine to standard-of-care multimodal analgesia.
