This randomized, crossover clinical trial evaluated the efficacy and safety of tadalafil compared with darifenacin in managing lower urinary tract symptoms (LUTS) and pain related to indwelling ureteric stents. A total of 150 patients who underwent ureteric stent insertion after endoscopic treatment of ureteric stones were enrolled. Patients were randomized into two groups: Group 1 received tadalafil 5 mg once daily for 3 weeks, followed by a 1-week washout, then darifenacin 7.5 mg once daily for 3 weeks. Group 2 received the reverse sequence. The primary outcome was change in LUTS as measured by a shortened International Prostate Symptom Score (IPSS). The secondary outcome was stent-related pain measured by the Numeric Pain Rating Scale (NPRS). Drug safety and tolerability were also assessed.
