Asymptomatic renocolic fistula as a complication of staghorn calculus: case report.Arch Esp Urol. 2013 Oct; 66(8):817-9.AE
To report a complication of a staghorn stone in a non-functioning right kidney.
We present a 47 year old female with right lumbar pain and history of recurrent urinary tract infection (UTI). After an acute pyelonephritis episode, a right staghorn stone was diagnosed in a non-functioning right kidney.
During right nephrectomy, we found a renocolic fistula not observed in the imaging studies before surgery. We performed a simple closure of the colon wall after resection of the fistula.
Asymptomatic renocolic fistula is a rare complication of an acute pyelonephritis secondary to a staghorn stone.
