Title: Xanthogranulomatous pyelonephritis, the gatekeeper's dilemma: a contemporary look at an old problem. Author: Nataluk EA, McCullough DL, Scharling EO. Journal: Urology; 1995 Mar; 45(3):377-80. PubMed ID: 7879331. Abstract: OBJECTIVES: To review 12 patients with a clinicopathogenic diagnosis of xanthogranulomatous pyelonephritis (XGP) and to determine if a computed tomography (CT) scan is the imaging procedure of choice for diagnosis. METHODS: A retrospective review, over the last 12 years, of patients with XGP at our institution. RESULTS: Nine of 10 patients (90%) who were evaluated by CT scan had the correct diagnosis made prior to nephrectomy. The most common presenting symptoms and signs were flank pain (64%), leukocytosis (73%), and anemia (82%). Seventy-five percent of the patients had a ureteropelvic junction stone or a staghorn stone in the affected kidney at the time of clinical presentation. Proteus was the most common organism cultured. CONCLUSIONS: After reviewing the clinical features of these 12 patients, we recommended CT scan to evaluate the patient in whom clinical suspicion of XGP is entertained. CT has proven to be the most accurate imaging study to evaluate this disease.[Abstract] [Full Text] [Related] [New Search]
