Sulfamonomethoxine-Induced Urinary Calculiin Pigs

The authors report a case of swine urolithiasis caused by improper administration of sulfamonomethoxine and which was diagnosed by examination of urinary sediments and analyzing the composition of the uroliths. The chemical composition of urinary calculi obtained from affected pigs with urolithiasis was further confimed as sulfamonomethoxine by fourier transform infrared (FTIR). It is suggested that appearance of typical fanlike or wheat bunchy crystals in urinary sediments under observation of lightmicroscope and determination by FTIR for the crystals are helpful in diagnosing sulfa calculi causced swine urolithiasis.
