Outcome of α-blockers, with or without methylprednisolone combination, in medical expulsive therapy for lower ureteric stones: A prospective randomised study

Abstract

ObjectivesTo compare the safety and efficacy of tamsulosin, alfuzosin, and their combinations with methylprednisolone, in the medical management of lower ureteric stones. Patients and methodsBetween September 2012 and June 2014, patients diagnosed with a single lower ureteric stone of ⩽10mm (longest dimension) were enrolled. Patients with urinary tract infection, severe hydronephrosis, pregnancy, hypertension, diabetes, ulcer disease, or renal insufficiency were excluded. According to the medication added to the analgesic anti-inflammatory, patients were stratified into four groups, with 53 patients in each. Group I patients received tamsulosin 0.4mg and those in Group II received tamsulosin 0.4mg and methylprednisolone 8mg. Group III patients received alfuzosin 10mg and those in Group IV received alfuzosin 10mg and methylprednisolone 8mg. Treatment was continued until stone expulsion or to a maximum of 2weeks. The patients’ demographics, stone criteria, and stone-free rates were calculated and analysed. ResultsThe mean (SD) maximum stone dimension was 7.8 (1.5), 8.1 (1.3), 7.9 (1.6) and 8.0 (1.4)mm in Groups I, II, III and IV, respectively. Groups II and IV had significantly higher stone-free rates than Groups I and III (P<0.05), whilst there were no statistically significant differences between Groups I and III or between Groups II and IV. There was no statistical difference among the four groups for the time to stone expulsion. Three patients in Group II and two patients in Group IV developed transient hyperglycaemia, which resolved after cessation of methylprednisolone. ConclusionsThe combination of alfuzosin or tamsulosin with methylprednisolone seems to be effective and safe for managing lower ureteric stones of <1cm.
