“…Typically, patients present with fevers, malaise, weight loss, and urine cultures growing out Escherichia coli , Proteus mirabilis , and Pseudomonas aeruginosa may be polymicrobial. Laboratory abnormalities are often nonspecific, with anemia, leukocytosis, elevated erythrocyte sedimentation rate (ESR), and abnormal liver function tests [2–5]. Such was the case in our patient who had a left-sided staghorn calculus, a polymicrobial culture, elevated WBC, low hematocrit, elevated ESR, and elevated alkaline phosphatase.…”

We present a case of a patient with xanthogranulomatous pyelonephritis (XGP) presenting with a large (18 × 12 cm) left-sided flank mass with worsening left flank pain. CT abdomen/pelvis demonstrated a left kidney with parenchyma replaced by multiple large hypodense collections containing fluid and gas, a left staghorn calculus, and a communication between the kidney and large flank collection. About 4.5 weeks after initial presentation, the patient underwent operative intervention. Pathology revealed an end-stage kidney with scar consistent with xanthogranulomatous pyelonephritis.

“…Diagnosis is often by CT scan, which may also differentiate XGP from emphysematous pyelonephritis [5]. The classic finding on CT with IV contrast is the “bear paw sign,” marked by a centrally obstructing stone with low-attenuating surrounding hydronephrotic parenchyma [1].…”

“…The most common urinary pathogen identified was Escherichia coli [3], and common areas of involvement were the retroperitoneum and psoas muscle. In our patient, the retroperitoneal space was surprisingly not greatly involved, but rather it was the anterior preperitoneal space that had significant adhesions and inflammation.…”

Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic pyelonephritis with progressive loss of renal function. Commonly, obstructing urinary calculi are seen. It is difficult to differentiate between XGPN and malignancy in many cases, and the diagnosis is usually only confirmed post-operatively upon histopathological examination of the specimen. Surgical treatment is often the main treatment modality due to suspicion for malignancy. Here, we present a case of XGPN that presented with abdominal distension, which was eventually discovered to be due to a preperitoneal abscess.

Acute kidney injury from pyelonephritis in an elderly man: case report

et al. 2011

View full text Add to dashboard Cite

Pyelonephritis is rarely considered in the differential diagnosis of acute kidney injury. Acute non-obstructed bacterial pyelonephritis is an infrequent and rarely considered cause of rapidly progressive acute kidney injury. A diagnostic challenge thus develops as it is difficult to clinically differentiate acute kidney injury secondary to ischemic or toxic acute tubular necrosis or papillary necrosis versus acute interstitial nephritis secondary to drugs or infectious pyelonephritis. We describe a case of acute kidney injury due to suppurative pyelonephritis in an elderly immunocompetent man who presented with dysuria, vomiting, and fever and later found to have histologic and radiologic proven pyelonephritis as the cause of acute kidney injury in the absence of hypotension, nephrotoxic agents, non-steroidal analgesics, immunosuppression, urinary tract obstruction, or other structural anomalies. The patient was managed with antimicrobial therapy, hemodialysis, and a short course of corticosteroids.
