Efficacy and safety of tamsulosin oral-controlled absorption system, solifenacin, and combined therapy for the management of ureteric stent-related symptoms

Abstract

ObjectivesTo evaluate the efficacy of solifenacin, tamsulosin oral-controlled absorption system (OCAS), and the combination of both drugs on JJ stent-related symptoms using the validated Arabic version of the ureteric stent symptom questionnaire (USSQ). Patients and methodsIn all, 260 patients who had undergone JJ stenting of the ureter for different endoscopic urological procedures were postoperatively randomly assigned into four equal groups. Patients in Group I received no treatment and served as the control group, Group II patients received tamsulosin OCAS 0.4mg daily, Group III patients received solifenacin 5mg daily, and Group IV patients received a combination of both drugs. Before stent removal, all patients completed the Arabic version of the USSQ. ResultsIn all, 234 patients completed the study, comprised of 56 in Group I, 59 in Group II, 58 in Group III, and 61 in Group IV. Baseline characteristics and indications for JJ stenting were comparable in the four groups. There were highly significant differences in all items of the USSQ between the treatment groups and the controls, while Group II and III were comparable. The USSQ score was significantly lower in Group IV vs Groups II and III. Crossing of the distal curl of the stent to the midline had a significant positive correlation with the severity of the urinary symptoms, body pain, general health, and work performance in the medicated groups. ConclusionsCombined therapy with tamsulosin OCAS 0.4mg daily and solifenacin 5mg daily is a safe and well-tolerated management for stent-related symptoms. However, stent position remains a significant factor affecting response to medical therapy and patients’ health-related quality of life.
