Obstructive urolithiasis is one of the major health problems in livestock animals, mainly in young calves. The present study was designed first to investigate the changes in the serum levels of Vitamins A and D in buffalo calves () with obstructive urolithiasis and second to investigate the efficacy of tube cystostomy technique in management of such condition.
One hundred and forty-nine buffalo calves of variable ages ranged from 3 to 7 months with a history of retained urine were examined clinically and ultrasonographically. Then, they were subjected to surgical treatment using the tube cystostomy technique. The serum levels of Vitamins A and D were investigated in retained urine calves in addition to 10 clinically healthy calves of the same age used as a control group.
Based on clinical and ultrasonographic findings, the calves were diagnosed as obstructive urolithiasis with intact bladder (n=64 calves) or with bladder rupture (n=85 calves) with the peak incidence in winter months. Tube cystostomy was an efficient and quick surgical technique for the management of such condition and 95.3% of calves returned their normal urination within 7-14 days after surgery. Significant hypovitaminoses A and D were found between retained urine calves and control ones (p= 0.01 and 0.002, respectively).
Hypovitaminoses A and D suggested predisposing obstructive urolithiasis in buffalo calves, but further clinical studies are recommended for more confirmation. Surgical treatment using tube cystostomy technique is recommended for the management of obstructive urolithiasis in buffalo calves.
梗阻性尿路结石是家畜尤其是幼龄犊牛的主要健康问题之一。本研究旨在首先调查患梗阻性尿路结石的水牛犊牛血清中维生素A和维生素D水平的变化，其次调查套管膀胱造口术对此类病症的治疗效果。
对149头年龄在3至7个月、有尿潴留病史的水牛犊牛进行临床和超声检查。然后，采用套管膀胱造口术对它们进行手术治疗。除了10头同龄临床健康的犊牛作为对照组外，还对有尿潴留的犊牛血清中维生素A和维生素D水平进行了研究。
根据临床和超声检查结果，犊牛被诊断为膀胱完整的梗阻性尿路结石（64头犊牛）或膀胱破裂的梗阻性尿路结石（85头犊牛），冬季发病率最高。套管膀胱造口术是治疗此类病症的一种有效且快速的手术技术，95.3%的犊牛在术后7至14天内恢复正常排尿。有尿潴留的犊牛与对照组之间维生素A和维生素D严重缺乏（分别为p = 0.01和0.002）。
维生素A和维生素D缺乏提示水牛犊牛易患梗阻性尿路结石，但建议进一步进行临床研究以作更确切的证实。建议采用套管膀胱造口术治疗水牛犊牛的梗阻性尿路结石。
