Efficacy of tamsulosin in the medical management of juxtavesical ureteral stones.

PURPOSE: We evaluated the efficacy of the alpha1-adrenergic antagonist tamsulosin for conservative expulsive therapy in patients with ureteral colic due to juxtavesical stones. MATERIALS AND METHODS: A total of 60 consecutive symptomatic patients with stones located in the juxtavesical tract of the ureter were randomly divided into group 1--30 who received oral floroglucine-trimetossibenzene 3 times daily and group 2--30 who received 0.4 mg tamsulosin daily. The 2 groups received 30 mg deflazacort daily for 10 days plus cotrimoxazole 2 times daily for 8 days and 75 mg diclofenac injected intramuscularly on demand. Ultrasound followup and medical visits were performed weekly for 4 weeks. Stone passage rate and time, analgesic use, hospitalization and endoscopical intervention were evaluated. Statistical analysis was performed using the Student t test. RESULTS: The stone expulsion rate was 70% for group 1 and 100% for group 2. Mean stone size was 5.8 and 6.7 mm, respectively (p = 0.001). Mean expulsion time was 111.1 hours for group 1 and 65.7 hours for group 2 (p = 0.020). The mean number of diclofenac injections was 2.83 for group 1 and 0.13 for group 2 (p <0.0001). Ten group 1 patients were hospitalized, of whom 9 underwent ureteroscopy, compared with none in group 2 (p <0.0001 and 0.001, respectively). CONCLUSIONS: Tamsulosin used as a spasmolytic drug during renal colic due to juxtavesical calculi increased the stone expulsion rate and decreased expulsion time, the need for hospitalization and endoscopic procedures, and provided particularly good control of colic pain.[1]
