Clinical Trial Summary

This is a prospective, double-blind, randomized, open-label, single-center trial of up to 78 participants who are adult patients (aged 18-80 years) and are undergoing unilateral retrograde ureteroscopy with planned ureteral stent placement for treatment of urinary tract stones. Eligible patients will be randomly and divided into two groups in a 1:1 ratio. Group A will receive fexofenadine 180 mg once daily in addition to standard of care treatment. Group B will receive placebo in addition to standard of care treatment. The routine standard of care treatment will consist of oral non-steroidal anti-inflammatory drugs (NSAIDs). The primary outcomes of the study are the Ureteral Stent Symptom Questionnaire (USSQ) urinary symptom score and pain score. Secondary outcomes include (i) number of office phone calls due to urinary symptoms; (ii) duration of analgesic use; (iii) duration and quantity of narcotic use; (iv) number of emergency department visits; (v) drug-related adverse effects; (vi) other domains of the USSQ.

Description:

Ureteral stents treat ureteral obstruction, allow for passive dilation of the ureter, maintain urine flow to the bladder, and aid in the recovery of the ureter after endoscopic surgery or ureteral injury. These stents are routinely utilized after urologic procedures for the treatment of urolithiasis and are generally kept in place for 1-2 weeks following the procedure. Despite their advantages, indwelling ureteral stents cause discomfort and reduce patient quality of life. These symptoms are partially attributed to local irritation to the ureter and bladder. Bothersome stent-related symptoms include urinary urgency, frequency, flank pain, hematuria, dysuria, sexual side effects, and emotional distress. The majority of patients with ureteral stents experience symptoms post-operatively. Several studies have indicated that agents such as antimuscarinics or alpha-1 adrenergic receptor antagonists may improve stent-related symptoms. The indications for anticholinergic medications are based on blocking involuntary bladder muscle contraction; however, the efficacy of these drugs is still controversial. Furthermore, these medications have potential adverse side effects. Antihistamines also show potential in alleviating stent-related symptoms. Multiple in vitro studies have shown H1 receptor activity involved both in ureteral peristalsis and in bladder contraction. Both first- and second-generation H1 antagonists have shown activity in the urinary tract. In clinical practice, antihistamines are commonly utilized in the management of bladder pain caused by interstitial cystitis. Additionally, a randomized controlled trial found efficacy of antihistamines for pain management in the setting of renal colic from obstructing ureteral stones. There is novel evidence that in patients with indwelling stents, there are inflammatory changes in the bladder with an associated eosinophilic reaction. Eosinophilic cystitis is commonly associated with bladder irritation or allergy, and these findings point to a novel paradigm of treating patients with antihistamines. To our knowledge, no studies have evaluated the efficacy of antihistamines for managing stent-related symptoms.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in USSQ urinary symptom score	Ureteric Stent Symptoms Questionnaire (USSQ) is a self-administered questionnaire to evaluate the overall impact of ureteral stents on different aspects of life. Urinary symptom will be assessed at different time points. The urinary symptom section consists 11 questions. A sum of the total score can range from 11 to 54 points. High score indicates worse outcome.	At time of initial visit (prior to surgery - baseline), at time of stent removal (1-2 weeks after surgery), at time of follow-up (4-6 weeks after stent removal)
Primary	Change in USSQ body pain score	Ureteric Stent Symptoms Questionnaire (USSQ) is a self-administered questionnaire to evaluate the overall impact of ureteral stents on different aspects of life. Body pain will be assessed at different time points. The body pain section consists 7 questions. A sum of the total score can range from 6 to 37 points. High score indicates worse outcome.	At time of initial visit (prior to surgery - baseline), at time of stent removal (1-2 weeks after surgery), at time of follow-up (4-6 weeks after stent removal)
