Chronic acid ingestion promotes renal stone formation in rats treated with vitamin D3

OBJECTIVE: Although hypercalciuria, a well-established adverse effect of vitamin D3, can be a risk factor of renal stone formation, the risk of nephrolithiasis has not been well defined. The consumption of a diet high in acid precursors is often cited as a risk factor for the development of calcium-based kidney stones. In the present study, we investigated the effect of chronic acid ingestion on kidney stone formation in rats treated with calcitriol (1-25[OH]2 D3). METHODS: Control rats (C-C), calcitriol-treated rats (C-V; three treatments of 0.5 microg of calcitriol per week) and acid-ingested (water containing 0.21 mol/L NH4Cl), calcitriol-treated (three treatments of 0.5 microg of calcitriol per week) rats (A-V) were fed in metabolic cages. After 1 month, urine, blood, kidney and bone samples were analyzed. RESULTS: The A-V rats exhibited elevated serum calcium concentrations, urinary calcium and phosphate excretion, urinary type I collagen cross-linked N-peptide (NTx)/creatinine values, mRNA expression of osteopontin in the kidney, and renal calcium contents as well as decreased bone mineral densities, compared with the C-C and C-V rats. Urinary citrate excretion was lower and NaDC-1 mRNA expression in the kidney was higher in the A-V rats than in the C-C and C-V rats. Calcium phosphate kidney stones were found in the A-V rats. CONCLUSIONS: The ingestion of NH4Cl, an acid precursor, promotes calcium phosphate kidney stone formation in calcitriol-treated rats. The chronic intake of a diet rich in acid precursors may be a risk factor for the development of kidney stones in subjects who are being treated with calcitriol.     

Percutaneous nephrolithotomy of a staghorn stone in thoracic ectopic kidney

Congenital thoracic ectopic kidney is a very rare developmental anomaly and the rarest form of all ectopic kidneys. It is usually asymptomatic and discovered incidentally on routine chest radiography. Herein we reported the first case of staghorn stone in a thoracic kidney managed successfully by percutaneous nephrolithotomy.     

128例肾输尿管结石临床分析

目的为探讨肾输尿管结石的临床特点,以提出更好的防治措施。方法对原西南师范大学医院1997-2004年治疗的128例肾输尿管结石病例的临床资料进行统计分析。结果本组病例男女之比为2.05∶1,29岁以下发病103例,占80.5%。2001年起发病呈上升趋势,2003年最高。每年9-10月是发病高峰,占本组病例的31.2%。经体外震波碎石99例,3个月结石排净率为83%,与文献报道的基本一致。结论该校肾输尿管结石患者,男性多于女性,30岁以下居多。发病近年增加,体外震波碎石疗效好。     

Abdominal ultrasonography in the diagnostic work-up in children with recurrent abdominal pain

We report on our experience with routine abdominal ultrasonography in 120 children (aged 3–15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. Conclusion The diagnostic value of abdominal ultra‐sonography in unselected children with recurrent abdominal pain is low. However, the direct visualization of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain.

Direct effect of cadmium on citrate uptake by isolated rat renal brush border membrane vesicles

High incidence of multiple kidney stone formation has been observed among workers exposed to cadmium (Cd). Citrate is known to be a protective factor against renal stone formation. To study the direct effect of cadmium on citrate uptake by the renal brush border membrane, we exposed isolated rat renal brush border membrane vesicles (BBMV) to cadmium and determined their citrate uptake characteristics. BBMV were prepared by the divalent cation precipitation method. Citrate uptake was measured by the Millipore rapid membrane filtration technique. Preincubation of BBMV with 2 and 10 mM CdCl₂ for 1 min significantly inhibited citrate uptake compared with that of BBMV without Cd. Analysis of the time course of citrate uptake during 30-min preincubation of BBMV with 0.5 mM Cd also revealed significant reduction of the uptake compared with that of the control BBMV without preincubation. These findings indicate that preincubation of BBMV with cadmium results in time-dependent and concentration-dependent inhibition of citrate uptake.     

THE INFLUENCE OF MULTIPLE FACTORS ON GALL BLADDER PRESSURE AFTER AURICULAR POINT STIMULATION

The study has explored 11 correlative variables which might affect the gallblad-der pressure GBP of patients with gall stone after auricular electrical stimulation by means of multiplestepwise regression. It was found that the size of gallbladder stone (X9), cholecystolithiasis (X4),sex (X1), and the baseline of GBP (X10) could affect the GBP change range (Y1) depressingly orreinforcingly. Also the baseline of GBP (Y1) could be affected by the variables X1 (sex), X2 (age),and X6 (long diameter of the gallbladder, LDGB), etc.. The result shows that the change in GBPafter auricular electrical stimulation is comprehensively influenced by multiple factors. And it providessome useful information for predicting the curative effect of auricular therapy on gallbladder stone inclinic.
