  3. [해외논문]   Current aspects of epidemiology and nutrition in urinary stone disease.  

    Hesse, A , Siener, R
    World journal of urology v.15 no.3 ,pp. 165 - 171 , 1997 , 0724-4983 ,

    초록

    Current examples for the development of urinary stone disease are discussed by means of data from the literature and our own studies. Urinary stone disease has gained increasing significance due to changes in living conditions, i.e., industrialization and malnutrition. Changes in prevalence and incidence, the occurrence of stone types and stone location, and the manner of stone removal are explained. The importance of nutrition in the prevention of calcium oxalate stone disease is discussed in terms of fluid intake, calcium and oxalate metabolism, and dietary fat intake. The results of a study on a standardized mixed diet or an ovo-lactovegetarian diet show that well-balanced nutrition with consecutive high intake of fluids leads to a significant decrease in the risk for urinary stone formation (calculated as relative supersaturation with calcium oxalate by the computer program EQUIL).

  4. [해외논문]   Prospective therapeutic studies in nephrolithiasis.  

    Ackermann, D K
    World journal of urology v.15 no.3 ,pp. 172 - 175 , 1997 , 0724-4983 ,

    초록

    Prospective randomized trials with respect to stone prophylaxis deal mainly with idiopathic calcium stone disease. There is a lot of evidence that alkali citrate, thiazides and allopurinol are effective in many patients. However, appropriate patient selection seems to be crucial. Alkali citrate and allopurinol have proven clinical efficacy in patients with hypocitraturia or hyperuricosuria, respectively. The correct method of patient selection for treatment with thiazides remains unclear. Despite the lack of prospective randomized trials, it is generally accepted that the first steps in the prophylaxis of idiopathic calcium stone disease are high fluid intake and a sensible diet.

  5. [해외논문]   Risk formulas in calcium oxalate urolithiasis.  

    Tiselius, H G
    World journal of urology v.15 no.3 ,pp. 176 - 185 , 1997 , 0724-4983 ,

    초록

    In order to reflect the risk of calcium stone formation, risk formulas have been described in the literature with the objective of being able to predict the further course of the stone disease. Some of these formulas are reviewed in this paper. Various results were obtained when different risk expressions were related to the severity of the stone disease. Although a reliable prediction of the future course of the disease most certainly cannot be made by analysis of the variables included in these expressions, several of the risk formulas differed significantly between patients with and without recurrent stone formation during a reasonable follow-up period. Some risk formulas might thus be helpful, at least to some extent, in selecting those patients in whom continuous stone formation can be anticipated and in whom active therapeutic measures should be beneficial and worthwhile. With an increased understanding of the mechanisms of calcium oxalate stone formation and our possibilities of measuring the relevant risk factors, it is likely that improved risk formulas with an increased predictive power can be developed. Until this becomes a reality, in most cases we have to combine important information on the history and clinical observations of the disease with a risk formula that offers a high degree of discrimination with respect to the risk of further stone formation.

  6. [해외논문]   Genes in idiopathic calcium oxalate stone disease.  

    Goodman, H O , Brommage, R , Assimos, D G , Holmes, R P
    World journal of urology v.15 no.3 ,pp. 186 - 194 , 1997 , 0724-4983 ,

    초록

    An examination of the urinary excretions of 101 normal subjects indicated that the major genetic influence on calcium excretion is a codominant pair of alleles giving rise to three phenotypes, low, intermediate and high (hypercalciuric) excretors. This inference was based on variance, Hardy-Weinberg and segregation analyses. Similar independent gene pairs also appear to influence oxalate and citrate excretion, A 3-locus Hardy-Weinberg table using estimates of gene frequencies derived from the study of normals suggests that only 3 or 4 leading genes are involved in oxalate stone disease. Strong candidate genes identified from molecular and physiological studies cannot be proposed at present, but it is assumed that they influence the transport of these ions in either the intestine, kidney or both organs. The identification of the genes involved should be facilitated by the reduction of dietary influences on urinary excretions through the use of formula diets.

  7. [해외논문]   Treatment update on pediatric urolithiasis.  

    Esen, T , Krautschick, A , Alken, P
    World journal of urology v.15 no.3 ,pp. 195 - 202 , 1997 , 0724-4983 ,

    초록

    At the doorstep of the twenty-first century the role of extracorporeal shock-wave lithotripsy (ESWL) as the treatment of choice for more than 80% of all stones in children is established. ESWL is safe and effective, with very few differences in success rates being observed among different lithotriptors. The present problem with ESWL appears to be the residual stone fragment, which has a proven clinical significance. A thorough metabolic evaluation and metaphylaxis is indicated in all children, and this will enable physicians to deal with the residual fragments in a more cause-specific manner and prevent regrowth. Another subject that needs prospective randomized studies to be unveiled is the assumption that a specific or universal metaphylaxis, possibly with alkaline citrates, will enhance stone clearance, lower the incidence of residual stone fragments, and optimize the ESWL results. Finally, both percutaneous nephrolithotomy and ureteroscopic stone removal have been established in children as safe and effective treatment options. This gives the clinician the opportunity to choose from a wide range of treatment alternatives, including open surgery, and only this approach will ensure 100% stone removal in individual patients along with the prevention of recurrence and, thus, the elimination of long-term morbidities in this vulnerable patient population.

  8. [해외논문]   Multiple primary tumors: 17 cases of renal-cell carcinoma associated with primary tumors involving different steroid-hormone target tissues.  

    Di Silverio, F , Sciarra, A , Flammia, G P , Mariani, M , De Vico, A
    World journal of urology v.15 no.3 ,pp. 203 - 209 , 1997 , 0724-4983 ,

    초록

    The aim of this study was to analyze the characteristics of 17 women with renal-cell carcinoma (RCC) associated with other primary neoplasms occurring in steroid-hormone target tissues. The reproductive history of these patients and the use of exogenous hormones were taken into consideration. In all, 10 RCCs were associated with breast carcinoma; 4, with endometrial carcinoma; and 3, with ovarian carcinoma. The presentation of a second primary tumor was described as synchronous or metachronous by evaluation of the interval between the discovery of the two neoplasms. Hormone and surgical treatment as well as pathologic findings for each primary tumor were also reported. In these 17 RCCs the overall rate of disease-specific survival recorded after a mean follow-up period of 32.7 months (range 9-66 months) was 58.8%; 7 patients died of metastatic disease after surviving for a mean of 14.7 months. In terms of the pathologic stage of RCC, a significant difference in mean survival was found between pN0 (mean survival 22.1 +/- 3.4 months) and pN1 RCCs (mean survival 13.7 +/- 3.5 months). A total of 13 (76.4%) women were postmenopausal at the time of diagnosis of the first primary tumor; the mean age of these women at menopause was 51.7 +/- 1.2 years. No prior use of oral contraceptives was reported by 12 (70.5%) of the 17 patients. Plasma 17-beta-estradiol and estrone levels were determined in only 7 patients at the diagnosis of each of the primary tumors. High plasma estrogen levels were found in 4 women with RCC and breast carcinoma and in 1 patient with RCC and endometrial carcinoma; in the remaining 2 patients low-normal values were found. A relationship appears to exist between certain reproductive and hormone-related factors and the risk of developing these tumor associations. Data emerging from the present study do not provide strong support for the hypothesis of hormone dependency of RCC; however, a role for estrogens in cases in which RCC is associated with other primary tumors involving steroid-hormone target tissues can be hypothesized.
