چکیده

یکی از مهم­ترین عواملی که در پاتوژنز سنگ­های ادراری نقش دارد، کریستال­اوری می­باشد. نوع کریستال می­تواند با عفونت باکتریایی دستگاه ادراری مرتبط باشد و متعاقبا موجب تغییر pHادرار ­گردد. مطالعه حاضر، با هدف ارزیابی فراوانی کریستال­اوری و باکتری­اوری، در سگ­های خانگی اهواز صورت گرفت. بدین منظور، ادرار 101 قلاده سگ سالم  و به روش کاتترزدن اخذ شد. در ارزیابی فیزیکی نمونه­های ادرار، وزن مخصوص، رنگ، شفافیت و ویژگی­های ظاهری و در آنالیز بیوشیمیایی آن­ها، وجود هموگلوبین، گلوکز، پروتئین و اجسام کتونی در ادرار بررسی و نیز pHادرار سنجیده شد. رسوب ادراری، از نظر حضور کریستال­ها، کست­ها و سلول­ها هم ارزیابی شد. همچنین نمونه­های ادرار از نظر حضور باکتری­­های استافیلوکوکوس، پروتئوس و اشریشیا کولای بررسی شدند. در مجموع، در 20 مورد (80/19 درصد) کریستال­اوری مشاهده گردید، که از این تعداد، 15 مورد (75 درصد) استروویت، 2 مورد (10 درصد) اگزالات­ کلسیم ­دی­هیدرات، 2 مورد (10 درصد) مخلوط استروویت و اگزالات ­کلسیم ­دی­هیدرات و 1 مورد (5 درصد) مخلوط اگزالات ­کلسیم­ دی­هیدرات و بیلی­روبین بودند. از 101 نمونه، در 40 مورد (60/39 درصد) کشت ادرار  مثبت بود، که از این تعداد، 16 مورد (40 درصد) استافیلوکوکوس اپیدرمیدیس و 12 مورد (30 درصد) اشریشیا کولای بود. در هیچ­کدام از نمونه­ها، پروتئوس جدا نشد. در مطالعه حاضر، ارتباط معنی­داری بین جنس و نژاد با باکتری­اوری و کریستال­اوری به­دست نیامد (05/0<p)، اما تفاوت از نظر سن معنی­دار بود به­نحوی که با افزایش سن، میزان کریستال­اوری و باکتری­اوری افزایش یافت (05/0>p). همچنین مشخص گردید که همبستگی نزدیکی بین کریستال­اوری و باکتری­اوری در سگ­ها وجود دارد.

چکیده [English]

Crystalluria is one of the most important factors contributing to the pathogenesis of urinary stones. The type of the present crystal in urine can be associated with urinary tract infection and bacteriuria. The aim of the present survey was to evaluate the frequency of crystalluria and bacteriuria in companion dogs of Ahvaz district. For this purpose, the urine of 101 healthy dogs was obtained by catheterization. Physical assessment was initially carried out for specific gravity, color, clearance and apparent characteristics, and then the biochemical analysis was performed on the presence of hemoglobin, glucose, protein, ketone bodies and pH in urine. Urinary sediment was also evaluated for the presence of crystals, castes and cells. Urine specimens were investigated for the type of Staphylococcus, Proteus and Escherichia coli bacteria. Overall twenty cases (19.80%) had crystalluria; of these numbers, fifteen cases (75%) were struvite, two cases (10%) oxalate calcium dehydrate, two cases (10%) mixed of struvite and oxalate-calcium dehydrate and one case (5%) mixed of oxalate calcium dehydrate and bilirubin. From out of 101 samples, 40 cases (39.60%) had positive urine culture; of that number, sixteen cases (40%) were positive for Staphylococcus epidermidis and twelve (30%) for E. coli. Proteus was not isolated in any of samples. There was no significant relationship between gender and breed with bacteriuria and crystalluria (p>0.05), but a significant difference was observed for age; so that with age rising, crystalluria and bacteriuria were increased (p
