Effects of an alpha-blocker and Terpene Mixture for Pain Control and Spontaneous Expulsion of Ureter Stone / 대한비뇨기과학회지

ABSTRACT

PURPOSE: It was known that alpha-1 receptors are present in ureteral smooth muscle. We aimed to reveal the effect of an alpha-blocker (tamsulosin) and terpene mixture (Rowatinex(R)) on the expulsion of ureter stone (size less than 1cm), as well as its affect on the relief of pain. Material and Methods: The patients were classified into group A in which the size of the ureter stone less than 4mm (144 subjects) and group B in which the size of stone was between 4mm and 10mm (48 patients). Each study group was also further divided into 3 sub-groups group 1 with analgesics only, group 2 with Rowatinex(R) as well as analgesics, and group 3 with 0.4mg of tamsulosin as well as analgesics. RESULTS: It was shown that the expulsion rates of ureter stone in sub-group 1 of group A, at the end of first week, was statistically lower (p<0.05) compared to that of sub-group 2 with Rowatinex(R). It was also shown that compared to sub-group 1, the expulsion rate of ureter stone at the end of first week in sub-group 3 was statistically significant (p<0.05). Compared to the consumed amount of analgesics in group A, it was revealed that sub-group 2 and sub-group 3 used statistically fewer ampules of than sub-group 1 (p<0.05). CONCLUSIONS: Our study clearly showed that both alpha-blocker and Rowatinex(R) are effective means of controlling colicky pain and they speed up excretion of ureter stones that are less than 4mm in size, at the end of first week. Therefore, we conclude that an alpha-blocker and Rowatinex(R) should be considered as an adjuvant regimen and this is beneficial for patients with ureter stone less than 4mm in size.
