بررسی اثر عصاره هیدرو الکلی میوه گیاه سرو کوهی(Juniperus communis)بر انحلال سنگهای ادراری به سنگهای ادراری به صورت In vitro

Background and purpose:Urolithiasis is one of the most common diseases of urinary tract. Abdominal colicky pain, nausia, vomiting and hematuria are the major clinical findings. Treatments including oral drugs, lithitripsy, using ureteroscope and open surgery are expensive and may result in significant complications. The aim of this research was to find medications for dissolution of urinary sto...

[Clinical studies on the recurrence of urolithiasis (5). Diurnal variation in urinary pH and stone compositions].

Correlation of the composition of the urinary calculi with urine pH, especially of diurnal variation, and composition of urinary excretion was studied. Urine pH in the patients with uric acid stones was constantly low and urinary pH in the patients with apatite and struvite stones was always high. Diurnal variation was not observed. In patients with pure calcium oxalate stones, however, urinary...

Seasonal variations in the composition of urine in relation to calcium stone-formation.

1. A retrospective cross-sectional study was carried out on data derived from single 24 h urine collections from 246 male idiopathic calcium stone-formers. 2. The daily urine volume and pH and the exretions of calcium, oxalate, phosphate, creatinine and magnesium were related to the time of year when the urine was collected, and the saturation of urine with calcium oxalate and octocalcium phosp...

Modification of estimation of the urinary ion-activity products of calcium oxalate and calcium phosphate.

Tiselius proposed simplified estimates of the ion-activity products of calcium oxalate, calcium phosphate, and brushite as the AP(CaOx) index, the AP(CaP) index, and the AP(Bru) index, respectively, which allowed assessment of the urinary saturation levels of these lithogenic substances. A number of urinary variables (calcium, magnesium, oxalate, phosphate, citrate, urine volume, and pH) are ne...
