Abstract
Pyelonephritis is one of the most important diseases in the urology. Most of this disease was caused by the infection of bacteria, and the author studied the bacteriological aspect of acute and chronic pyelonephritis.
Patients under study were 63 cases who visited the Urology Department during the. period from May 1971 to April 1973 with some urological symptoms. They were classified into 21 cases of acute and 42 of chronic pyelonephritis. The main symptoms were flank pain, fever and chill, nausea and vomiting, and vesical irritability. As the predisposing factors or combined diseases, urolithiasis and hydronephrosis were most frequently noted.
The total bacterial count of urines showed that 46 cases were more than 10¢¥/mI and there were 17 cases which colony counts were 104 or less.
Bacteria isolated from urines of patients were classified by the description of Edwards and Ewing. Escherichia coli was mostly frequently found with 8 strains in. acute case and 12 in chronic cases, and followed by Kiebsiella, Enterobacter aerogenes and Proteus vulgaris in the decreasing order. Small numbers of Staphylococcus, Pseudornonas aeruginosa and Enterobacter liquefaciens were identified.
Antibody titers in sera of patients were titrated by means of hemagglutination test, and significant antibody production to homologous E. coli was noted in about two-thirds. of patients. The antibody production to the other causative organisms was very weak in most cases with the titer of 80 or less. No special relationship between antibody titer and the bacterial count of urine was noted.
