Long-term urethral catheterization (greater than or equal to 30 days), a management technique for urinary incontinence, results in polymicrobial bacteriuria. We frequently found urease-producing bacteria: of 1,135 weekly urine specimens from 32 long-term-catheterized patients, 86% had urease-positive bacterial species at greater than or equal to 10(5) CFU/ml. The most common species were Proteus mirabilis and Morganella morganii, each found in over half the specimens. P. mirabilis, but not other urease-positive species, was significantly associated with the 67 obstructions observed in 23 patients. M. morganii had a more complex association and in some way may protect the catheter from obstruction.
长期导尿(大于或等于30天)是一种治疗尿失禁的管理技术,会导致多种微生物性菌尿。我们经常发现产脲酶细菌:在来自32例长期导尿患者的1135份每周尿液标本中,86%的标本中脲酶阳性细菌种类的菌落形成单位(CFU)大于或等于10⁵/ml。最常见的菌种是奇异变形杆菌和摩根摩根菌,每种菌在超过一半的标本中被发现。奇异变形杆菌,而非其他脲酶阳性菌种,与23例患者中观察到的67次梗阻显著相关。摩根摩根菌的关联更为复杂,可能在某种程度上保护导尿管不被堵塞。
