Controversy exists over whether metabolic factors or urinary stasis predominate in the pathogenesis of calyceal diverticular calculi. We performed a study to better define the effects urinary stasis and metabolic abnormalities have in the p...

This investigation highlights the use of infrared microspectroscopy for the morphological analysis of urinary stones. The research presented here has utilized the reflectance mode of an infrared microscope for use in creating chemically spe...
Vitamin B6 deficiency augments endogenous oxalogenesis after intravenous L-hydroxyproline loading in rats [0.03%]
维生素B6缺乏可通过大鼠静脉注射L-羟脯氨酸增加内源性草酸盐生成

To investigate bone mineral densitometry findings in patients with normocalciuric urinary system stone disease, we compared 150 patients with normocalciuric calcium stone disease (group 1) and 60 subjects of a control group (group 2). The p...
In vitro effects of PDE5 inhibitors sildenafil, vardenafil and tadalafil on isolated human ureteral smooth muscle: a basic research approach [0.03%]

A retrospective analysis was done to determine the efficacy of shock wave lithotripsy (SWL) and ureteroscopy in the treatment of paediatric ureteral calculi. We reviewed the records of 67 (35 boys, 32 girls) children (71 ureters) admitted t...
Size does matter: 1.5 Fr. stone baskets almost double irrigation flow during flexible ureteroscopy compared to 1.9 Fr. stone baskets [0.03%]
大小确实有关系：与1.9Fr碎石篮相比，1.5Fr碎石篮几乎将经尿道输尿管镜灌注流加倍

With a new generation of flexible ureterorenoscopes, a new area in stone management is emerging. Limitation of vision with these new instruments is often caused by insufficient irrigation flow, especially when using instruments like stone b...
Inhibition of calcium oxalate crystallization by commercial human serum albumin and human urinary albumin isolated from two different race groups: evidence for possible molecular differences [0.03%]
商业人血清白蛋白和两种不同种族的人尿白蛋白对草酸钙结晶生长的抑制作用：分子差异的证据

Allen L Rodgers et al.
This study was undertaken to investigate the inhibitory activity of urine-derived (as opposed to serum-derived) albumin towards calcium oxalate crystallization and to compare the relative inhibitory strengths of this protein in subjects fro...
Pharmacological effect on pyeloureteric dynamics with a clinical perspective: a review of the literature [0.03%]
