いわゆる萎縮腎型腎盂腎炎に関する2,3の考察

Abstract

For the past 3 years (1952-1961) 8 cases of unilateral renal atrophy were observed in the Urologic Clinic of Kyushu University Hospital. There were 6 who had evidence of previous or present infection and 2 without infection. Incidence of hypertension was 25% for the entire group. Although 5 cases who were performed cystography showed unilateral or bilateral vesicoureteral reflux, the findings emphasized the difficulty in deciding clinically the importance of infection as a factor in renal atrophy. It appeared impossible to segregate the surgical specimens into separate pathologic groups. Nevertheless, on the basis of rather meager and unconvincing data, the cases were divided into : (1) 5 of chronic atrophic pyelonephritis ; (2) 3 of chronic atrophic pyelonephritis sup3rimpose3 on congenital hypoplasia and polycystic kidney. In some cases of apparent chronic atrophic pyelonephritis the kidney may have been congenitally small to start with, but there is no way of deciding this problem accurately.
