Objective: The aim of this paper was to assess the relationships among chemical, phase and structural composition and etiopathogenic factors of non-infectious phosphate calculi formed in patients with low and high urinary phosphate concentrations, and to characterize the mechanism of their formation related on biochemical results. Material and Methods: Twelve samples of phosphate renal calculi ...

IJANTITATIVE CHEMICAL ANALYSES of urinary calculi have been done in these laboratories for some twenty years. During this time almost two thousand stones have been examined. In the early days of this period, the only quantitative method available was that of a complete analysis of the inorganic ions and organic compounds present, which was quite difficult and tedious. After the development of t...

Objective: To analyze the chemical components of prostatic calculi. Method: An infrared automatic analyzer was used to determine the chemical components of prostatic calculi from 86 patients, and the causes of formation and related clinical data were examined. Results: Magnesium ammonium phosphate and carbapatite were found in 84.9% of calculi, and the difference in the comparison with urinary ...

Bladder calculi, a rare condition in the pediatric population, occur most commonly as a result of either migration from the kidney or urinary stasis in the bladder. We report the case of a 3-year-old boy with recurrent urinary tract infections (UTI) secondary to bladder calculi formation on the sutures from a previous herniorrhaphy.A 3-year-old boy with previous history of herniorrhaphy present...

To investigate whether prostatic calculi might influence the urinary retention (UR) probability, the quality of life (QOL) and the positive rate of cancer after prostate biopsy in middle-aged and old male with PSA higher than normal. This study comprised a retrospective analysis of data from 685 patients (prostatic calculi group 325 VS non-prostatic calculi group 360), those who had undergone t...

OBJECTIVE To determine the mineral composition of calculi, anatomic locations of the calculi, and findings of urinalysis and bacteriologic culture of urine and calculi in guinea pigs with urolithiasis. DESIGN Cross-sectional study. ANIMALS 127 guinea pigs. PROCEDURES Records of urinary calculi that had been submitted to the University of California Stone Laboratory from 1985 through 2003 ...

Male Wistar-strain rats which had been fed a glycolic-acid diet developed severe nephrocalcinosis with urinary calculi within 4 weeks. Rats fed the same diet with citrate salts added had, however, either slight or no nephrocalcinosis without any stones in the urinary system. Nephrocalcinosis intermediate between those in the citrate groups and the glycolic-acid group, with some urinary calculi,...

Urinary calculus is a medical condition characterized by the formation of hard deposits in urinary tract. It also known as kidney stones and can cause severe pain discomfort. The most common type composed calcium, but it be made other substances such uric acid or struvite. Risk factors for developing include dehydration, family history, certain conditions, medications. Urinary calculi ar...

Urinary calculi are the third most prevalent disorder of urinary tract and nearly 80% these composed calcium oxalate. There very few drugs available for management urolithiasis. Medicinal plants contained many constituents that work with minimum side effects to a large population. The current review focused on antiurolithiatic natural sources, hoping it was beneficial general public attract res...
