上部尿路感染に関する2,3の統計的研究 3.逆行性腎孟撮影後の発熱(感染)

Abstract

Incidences of fever after retrograde pyelographies were studied in 163 inpatients both with normal and diseased upper urinary tract or kidney. As is shown in Table 1, 42.3 per cent of the total cases were febrile after the procedure. The incidence was nearly the same in frequency both in the cases with cloudy urine and with clear urine (Table 2, 3, 4). In general, there was no intimate correlation between the degree of turbidity of urine and the degree of fever, though in the cases with turbid renal urine there was correlation to some extent (Table 5, 6). Dilatation of the upper urinary t ract (or stagnation in it) had such great influence upon the onset of fever occurring after retrograde pyelographies that encountered the greatest number of febrile cases (61.1 ro ; Table 1, 11) ; and moreover, once fever occurred its duration was much longer (6-10 days) than was usual. The greater the degree of dilatation, the longer the fever lasted (Table 7). Analyzing the incidence of fever in variou s case groups, the fever disappeared in 5 days in most cases with anatomically normal upper urinary tract. The duration of fever in relation to the turbidity of urine is tabulated in Table 8, 9 and 10. Correlation between the degree of pelvic dilatation and fever is shown in Table 11. When fever continued over 6 days there would be detected some stagnation (or dilatation) of the upper urinary tract, or organic changes of the renal parenchyma (other than tuberculosis) such as nephritis, pyelonephritis and tumor. It was of interest that the fe v er continues over 6 days in all the cases of renal bleeding with febrile after retrograde pyelography. This fact might suggest the existence of some sort of parenchymal lesion in the kidney.
