Renocolic fistulas are abnormal connections between the upper urinary tract and the colon. Chronic renal obstruction and delayed treatment of obstructive renal stones can lead to loss of renal function, inflammation of the kidney and surrounding structures, and the development of fistulas. However, due to the increased availability of CT scans and cystoscopy for diagnosis and treatment, renocolic fistulas resulting from obstructing renal stones have become rare. This article describes a patient who was found to have a renocolic fistula on antegrade percutaneous nephrostogram. The patient was treated with a laparoscopic nephrectomy and minimally invasive colon repair and recovered.

BACKGROUND Nephro-colic fistulas are uncommon, generally caused by local inflammation, trauma, or neoplasia affecting the kidney or the colon. Their association with a coralliform stone is described in a few case reports, but their management is difficult and differs quite a lot, depending on the clinical situation. We report an atypical clinical case of a reno-colic fistula associated with a staghorn calculus.

Here, we present a unique case of a woman with recurrent pyelonephritis, severe anemia, and unintended weight loss, who was eventually diagnosed with a colo-renal fistula. Delayed imaging following intraoperative fluoroscopy revealed the abnormal connection between the colon and upper urinary tract.

Xanthogranulomatous pyelonephritis is a rare and aggressive form of chronic pyelonephritis, it can occur at all age groups but is more common in women than in men, supposedly relating to the increased incidence of urinary tract infections and chronic nephrolithiasis in woman. Computed tomography (CT) findings are very helpful in making the correct diagnosis, but the definitive diagnosis is still based on histology, as there are many differential diagnoses such as renal cell carcinoma and renal tuberculosis. The complications of this type of pyelonephritis are due to the involvement of adjacent organs.
