Xanthogranulomatous Pyelonephritis with Renocolic Fistula and Coexistent Contralateral Renal Carcinoma

Abstract

The presence of contralateral renal tumour in a case eventually found to have Xanthogranulomatous Pyelonephritis (XP) resulted in a wrong preoperative diagnosis of tumour with bowel fistula. The patient's prior history of bladder tumour and multiple renal cysts is also discussed, along with the retrospective finding of very minor changes in an early angiogram.

Fistula and Sinus Formation in Xanthogranulomatous Pyelonephritis; A Clinicopathological Review and Report of Four Cases

“…Malek and Elder (1978) reported a patient with post-operative duodenocutaneous and colocutaneous fistulae. Tolia et al (1980) described a patient with XPN and persistent nephrocutaneous fistula and List et al (1983) reported a cast: of XPN with a renocolic fistula. Friedland et al (1983) described fistulae extending to other par1 s of the urinary tract, the gastrointestinal tract, the skin (even extending to unusual sites such as the buttock or axilla) and the lung.…”

Xanthogranulomatous Pyelonephritis: Clinical Experience with 62 Cases

“…Patients are typically in the fifth or sixth decade and the occurrence of pediatric cases, with peculiar aspects of the disease, is quite exceptional [29,38], Females are more frequently involved than males because of the higher incidence of urinary tract infections, and a 2:1 ratio has been reported [2], Renal cell carcinoma has occasionally been found to be associated with XGP [17,21,27].…”

Die Xanthogranulomatöse Pyelonephritis: Eine Übersicht mit Kasuistiken zur Differentialdiagnose und verlaufsorientierten Therapie

“…Es zeigt sich ein Druck-und Klopfschmerz in der betroffenen Flanke bei oft palpablem Tumor. Langdauernde Krankheitsverläufe können in selteneren Fällen mit der Ausbildung von Fistelgängen (reno-kolisch, reno-kutan, uretero-kolisch) und Arthritiden einhergehen (6,12,22,24,32,33,40).…”
