Analysis of Four Automated Urinalysis Systems Compared to Reference Methods.

Background: The aim of this study was to compare four automated urinalysis systems: the Iris iQ200 Sprint (Iris Diagnostics, U.S.A.

[Metaphylaxis in the first occurrence of urolithiasis].

Background: Urolithiasis is a socially important disease with a high tendency to recurrences. By specific medicamentous metaphylaxis it is possible to achieve an as high as tenfold reduction of recurrences, however, regular check-ups focussed on possible side-effects are required. The objective of the project was to assess prospectively the effectiveness of non-medicamentous metaphylaxis in patients with the first kidney stone.

A prospective study of nonmedical prophylaxis after a first kidney stone.

Objective: To assess, in a multicentre prospective randomized study, the effectiveness of specific nonmedical prophylaxis and nonspecific dietary prophylaxis in patients treated after experiencing their first idiopathic calcium-containing kidney stone.

Patients And Methods: From 1991 to 1994, 242 patients with idiopathic calcium urinary stones from three urological centres were randomly assigned into two groups. In group 1 (intervention, 113 patients), a specific dietary regimen was recommended and thereafter corrected according to a comprehensive metabolic evaluation.

Development of metaphylaxis in calcium urolithiasis: a restriction of conventional drug therapy.

Between 1978 and 1992 (mean 9.2 years), metaphylaxis was introduced to 110 patients originally hospitalized for recurrent urinary calcium stones (mostly bilateral or multiple). Patients with hyperparathyroidism or with sponge kidney were excluded from the study.

[Detection of metabolic disorders as a cause of urolithiasis in clinical practice].

Metabolic disorders are the most frequent risk factor for the development of urolithiasis. They are manigenic substances or deficiency of inhibitors of crystalgenic substances or deficiency of inhibitors of crystallization and aggregation. The authors use for their diagnosis a modification of Pak's procedure.
