title: [Renal lithiasis: the internist's viewpoint 1986].
abstract: This study is presented as a debate on nephrolithiasis by a urologist and an internist. The reason is that in 1986 the urologist has become successful at desintegrating almost any stone without open surgery, whereas the internist's approach to the same problem is entirely based upon an understanding of pathophysiological mechanisms. After having reviewed the major risk factors for renal stone disease, i.e. small urine volume, hypercalciuria, hyperoxaluria, hyperuricosuria, very high or very low urine pH and hypocitraturia, the author shows that now it is not only possible to selectively correct each of these disorders, but that in doing so the internist does change the natural history of the disease. For instance, definite remissions have been obtained by advising patients to increase water intake, by administering thiazides to hypercalciurics, pyridoxine to some hyperoxalurics, allopurinol to hyperuricosurics, urease inhibitors to struvite stone formers and citrate to hypocitraturics. Therefore, the author concludes that the role of the urologist and that of the internist are complementary: although the former now desintegrates the stone without open surgery, the latter, who takes care of the same patient next, is now largely able to prevent relapse of nephrolithiasis after determining the cause of the disease.
