“…Among the different types of fistulas that establish a connection between the urinary and intestinal tracts, reno-alimentary fistulas account for less than 1% of cases. Several underlying pathological processes can give rise to the development of such fistulas [ 2 , 9 ].…”

Reno alimentary fistula, a rare illness characterized by improper connection between the kidney and digestive tract, can lead to urinary tract infections, abscesses, and severe sepsis. It can also be caused by various factors such as chronic infections, malignancy, cryoablation, or abdominal surgical procedures. We present a case of a 60-year-old man with bilateral staghorn stones who was diagnosed with reno-duodenal fistula and underwent a right simple nephrectomy and fistula closure. The histopathology revealed a well-differentiated squamous cell carcinoma that originated from the renal pelvis.

We present a rare case detailing the investigations and subsequent treatment of a lady who presented with a reno-duodenal fistula and perinephric abscess as a complication of staghorn calculus and recurrent upper urinary tract infections. Treatment involved antibiotics, nephrostomy, endoscopic closure of the fistula tract with clips, radiological drain insertion and, ultimately, nephrectomy with primary omental patch closure of the duodenal defect. We discuss the incidence of fistula tract formation as a complication of staghorn calculi, as well as investigations and management strategies employed in the literature to treat such complications, which span from conservative treatment to nephrectomy and closure of the intestinal defect. We illustrate the post-operative complications such patients are prone to and discuss these in context of the case. Whilst such cases are rare clinicians should be vigilant for complications associated with chronic inflammatory processes occurring in the urinary tract and investigate accordingly.

“…Fistulae between upper urinary tract and the bowel are rare, with about a 150 cases described in literature, of which the the most common causes are nephrolithiasis, pyonephrosis and xanthogranulomatous pyelonephritis 1. Among traumatic cases, penetrating abdominal injuries and fistulas secondary to improper boluses piercing the duodenal curve and penetrating in the right urinary tract must be considered.…”

Spontaneous renoalimentary fistula as a complication of upper tract urothelial carcinoma: unknown complication of a rare disease

et al. 2019

Fistulae of the upper urinary tract with the alimentary tract are rare. Most cases of renoalimentary fistulae are secondary to penetrating trauma, which may be iatrogenic or due to locally invasive benign infective processes or complicated nephrolithiasis, or following surgical procedures. Spontaneous renoalimentary fistulae developing secondary to locally advanced malignancies, namely renal cell carcinoma, are very rare, and unknown due to upper tract transitional cell carcinoma. We present a case where a 60-year-old man, presented with clinical symptoms suggestive of upper gastrointestinal tract pathology, with no urological complaints and was diagnosed to have a renoalimentary fistula on cross-sectional imaging and upper gastrointestinal endoscopy with histopathology of duodenal growth biopsy showing high-grade transitional cell carcinoma. Due to unresectable nature of this mass, this patient had a gastric and biliary diversion and was started on palliative chemotherapy. Renoalimentary fistulae due to benign inflammatory causes may be treated by nephrectomy with or without resection of the involved bowel segment. However, all malignant fistulae have to be treated as locally advanced tumours and en bloc resection should be attempted whenever feasible.
