Pielonefritis xantogranulomatosa: Revisión de 10 casos

Abstract

Xanthogranulomatous pyelonephritis (XP) is a chronic and unusual inflammatory-infectious disease with acute episodes involving renal parenchyma. Most cases appear in medium aged women. Histopathologic study offers the accurate diagnosis. Antibiotic therapy avoids septic complications. Total or partial nephrectomy is the definitive treatment. We propose nephrostomy because it facilitates the microbiological diagnosis and surgery (nephrectomy).

Xanthogranulomatous pyelonephritis with calculus migration into the psoas abscess: an unusual complication

“…3 However, Leoni et al observed a mortality rate of 10% in a series of 10 patients, despite the nephrectomy. 11 Since our case could not be managed conservatively with only on antibiotics regimen, the abscess drainage and a left-sided nephrectomy were necessary to prevent the development of a septic shock. In cases of absence of the typical signs like staghorn calculus, the differential diagnosis of XGP, based strictly on imaging, includes renal tuberculosis, renal cell carcinoma, renal abscess, and renal angiomyolipoma.…”

Clinicopathological spectrum of xanthogranulomatous pyelonephritis

“…Clinical symptomatology of XGP is often nonspecific with fever, flank pain, palpable mass, malaise, anorexia, and weight loss being commonly observed. [818] Dysuria, frequency, pyuria, or hematuria may be experienced. Abscess formation (paranephric and psoas), fistula formation (renocutaneous and renocolonic), and sepsis are known complications.…”

Xanthogranulomatous pyelonephritis: A rare entity

“…It mainly occurs in adults with preponderance in females of younger age group. It usually involves single kidney and is associated with renal stones in 2/3 of cases and con-comitant infection with E. coli, Pro-teus mirabilis, Klebsiella spp, Staphylococcus au-reus, Enterococcus spp, Pseudomonas spp, Strep-tococcus spp , including anaerobic organisms[2]. …”
