One of the early classification systems was introduced by Michaeli et al; the plain radiograph and intravenous pyelogram were used to categorize EPN into three stages: Stage I describes gas in the renal parenchyma or perinephric
tissue; stage II describes gas in the kidney and its surroundings; and stage III indicates extension of gas through fascia or bilateral disease.
In the winter, n-6 PUFA levels were similar in all types of adipose tissue, and they were higher than those noted in subcutaneous, perinephric
and intermuscular fat in the summer.
A pre-and post-contrast CT scan of the abdomen and pelvis revealed a large right perinephric
hematoma within the anterior aspect of the retroperitoneum (Fig.
The post-mortem examination revealed RCC extending into the perinephric
fat and metastases to lymph nodes, liver, and lungs.
The hernia in our case contained perinephric
fat tissue bilaterally and intestinal segments on the left side.
The reported case of concomitant perinephric
and prostatic abscesses remind us of the ability of Staphylococcus aureus to result in metastatic infections and illustrates an emerging role of this pathogen to cause urinary tract infection.
Though a scan can't give any data on kidney function, it can help diagnose hydronephrosis, hydroureter, and perinephric
stranding--all of which are secondary signs of stones, she said.
Localization of retinol-binding protein messenger RNA in the rat kidney and in perinephric
Klebsiella pneumoniae urinary tract infection complicated by endophthalmitis, perinephric
abscess, and ecthyma gangrenosum.
e) Other etiologies include congenital kidney disease (n = 7), drug-induced nephritis (n = 7), nephrectomy for malignancy (n = 6), chronic pyelonephritis (n = 5), multiple myeloma (n = 1), and perinephric
hematoma (n = 1).
Nitrofurantoin is not indicated for the treatment of pyelonephritis or perinephric
Vascular invasion or perinephric
fat extension was reported in 2 tumours (5.
