Histopathological alterations were identified as focal nephropathy, glomerulonephropathy
, or tubuloi nterstitial lesions by Byung-il Yoon (College of Veterinary Medicine, Kangwon National University, Chuncheon, Korea).
Focal segmental glomerulosclerosis was present in 7 cases (Figure 3, A), collapsing glomerulopathy in 2 (Figure 3, B), and granulomatous tubulointerstitial nephritis in 2 (Figure 3, C); and there was 1 case each of acute pyelonephritis, thrombotic microangiopathy, atheroembolic disease (Figure 3, D), reflux nephropathy, proliferative glomerulonephropathy
, membranous glomerulonephropathy
, and secondary amyloidosis (serum amyloid A type).
Non-infectious conditions for pyuria include calculous disease, stricture disease, neoplasm, glomerulonephropathy
, or intersitial cystitis.
The primary renal lesion may have been glomerulonephropathy
, which was subsequently associated with tubular oxalosis as the secondary renal lesion.
In addition, Newell et al (99) reported that 50 to 100% of patients with hepatic cirrhosis caused by alcohol have an associated glomerulonephropathy
, histologically identical with immunoglobulin A nephropathy.
19) It was first reported in 1979 by Arakawa et al (20) as a possible new disease entity, who proposed a term collageno-fibrotic glomerulonephropathy
