The composition of 3,084 urinary calculi was determined using an infrared spectrophotometer. Mixed calcium oxalate-calcium phosphate stones were most frequently implicated. Of the urinary calculi analyzed 199 were associated with urinary tract infection. Escherichia coli was most frequently isolated (43 strains) and urease-producing organisms, such as Proteus mirabilis, were cultured from 40 patients. The core culture of 20 staghorn calculi yielded 15 isolates from 14 stones. There were 13 identical species isolated from the urine and stone specimens of 13 patients (65%), including 7 strains of P. mirabilis. These results suggest that cultures of urine specimens of urolithiasis patients, especially those with staghorn calculi, may help to elucidate the bacteriology of the stones.
使用红外分光光度计测定了3084块尿结石的成分。草酸钙 - 磷酸钙混合结石最为常见。在分析的尿结石中，199块与尿路感染有关。最常分离出的是大肠杆菌（43株），并且从40名患者中培养出了产脲酶的生物体，如奇异变形杆菌。20块鹿角形结石的核心培养物从14块结石中产生了15株分离菌。从13名患者（65%）的尿液和结石标本中分离出13种相同的菌种，其中包括7株奇异变形杆菌。这些结果表明，尿路结石患者，尤其是鹿角形结石患者的尿液标本培养，可能有助于阐明结石的细菌学情况。
