Introduction: A lower ureteric calculus is one of the most commonly encountered conditions in daily urological practice. There are various options for management of lower ureteric calculus, which includes watchful waiting, extracorporeal shock wave lithotripsy (ESWL), and ureteroscopic lithotripsy (URSL). The aim of our study was to evaluate the efficacy of following drugs in the expulsion of a lower ureteric calculus ≤ 10 mm. The drugs used are (1) tamsulosin, (2) naftopidil, (3) tamsulosin and deflazacort, and (4) naftopidil and deflazacort.
Methods: A prospective study was carried out in the Department of Urology from August 2012 to January 2013. A total of 150 patients were enrolled and were randomized into 5 equal groups of 30: A (control), B (naftopidil), C (tamsulosin), D (naftopidil and deflazacort), and E (tamsulosin and deflazacort). Complete hemograms; blood urea; serum creatinine; urine routine examination and culture and sensitivity; X-ray of the kidney, ureter, and bladder (KUB); and/or ultrasonography were done in all cases. Cases were followed up to 30 days or upon spontaneous passage of the calculus, whichever was earlier. X-ray KUB and/or ultrasonography were done to confirm the passage of the stone.
Results: The expulsion rate for a calculus ≤ 10 mm was statistically significant in all the groups in comparison to the control group. The mean days of expulsion and use of analgesics was also low in all the groups compared to control. Amongst all groups, the stone expulsion rate was highest, and episodes of pain and mean days of expulsion were lowest for the D group.
Conclusion: It is concluded that alpha-adrenergic blockers facilitate the expulsion of lower ureteric stones ≤ 10 mm and decreases the episodes of colic, which is further improved by the addition of deflazacort. Naftopidil plus deflazacort gives the best results in regards to stone expulsion rates, mean days of expulsion, and episodes of colic.
