Communicating Fistula Between Colocutan and Nephrocutan With Renal Stones and Renal Replacement Lipomatosis. A Case Report

Abstract

Colocutaneous fistula with nephrocutaneous fistula is a rare condition. Renal replacement lipomatosis is the result of the atrophy and destruction of renal parenchyma. We report a 60-year-old male with intermittent drainage mucus and fluid from ulcer of his right lumbar region. Renal ultrasound and plain abdominal X-ray revealed a chronic parenchymal disease with stone of the right kidney. Fistulography showed a fistula tract connecting the skin and the right pelvicalyceal system and the colon. Computerized tomography demonstrated a renal calculus with a massive fatty proliferation. The patient was planned for right nephrectomy and excision of the sinus tract.

Mucinous Adenocarcinoma (Signet Ring Cell Carcinoma) of the Urinary Bladder in Young Male: A Case Report

“…This lesion is associated with long-term intestinal metaplasia, chronic irritation, and obstruction such as schistosomiasis and non-functioning urinary vesicles. Pelvic lipomatosis is also mentioned as a risk factor (8,11). This patient did not have any congenital disorder but the patient had a history of recurrent urinary tract stones.…”

Spontaneous appendico-renal fistula: clinical presentation and management of a previously unreported entity

“…Reno-colic and reno-cutaneous fistula have been described in its presence. Rare presentations, such as reno-pleural fistula, are also described as a complication of chronic pyelonephritis 3–5. However, neither renal pathologies nor appendicitis complications are known to incite appendico-renal fistula as such.…”

A surfacing staghorn: Spontaneous expulsion of a large renal calculus from a nephrocutaneous fistula

“…There are a small number of isolated case reports of spontaneous nephrocutaneous fistulae. The most frequently reported causes of spontaneous nephrocutaneous fistulae in the literature were staghorn calculi or multiple renal stones [10][11][12][13][14][15][16][17][18][19][20][21] associated with infection, particularly xanthogranulomatous pyelonephritis. 10,14,15,17 Other less common causes reported included ureteric stones, 22 renal tuberculosis 18,23 and renal replacement lipomatosis.…”

“…On review of the literature, many patients presented in a similar manner to our patient, with an intermittently discharging lesion from the flank where on examination one or multiple sinuses could be seen. [10][11][12][13][14][16][17][18][19][20][21][22][23] Some had subcutaneous swellings that had increased in size prior to rupturing. 17,21 Duration of symptoms varied from 3 months to 14 years.…”
