Hi,
How are you? Majority of
stones 4 mm or less in size usually will pass spontaneously, however majority of
stones larger than 6 mm will require some form of intervention. Before doing any surgical intervention, many doctors try conservative measures such as alpha adrenergic blocking agent ( Flomax, Uroxatral, terazosin or doxazosin), which acts to reduce the muscle tone of the ureter and facilitate stone passage.
