Radionuclide renography: a seldom used test for the detection of vesicoenteric fistula.

Hellenic Journal of Nuclear Medicine ñ September December 2007 of a colorectal or bladder malignancy [7]. Most vesicoenteric fistulas in children are congenital and associated with anorectal malformation or cloacal anomalies [8]. The clinical manifestations are principally urological in the form of recurrent urinary infection and terminal pneumaturia. The most useful diagnostic techniques are cystoscopy serial voiding cystourethrography (SVCU), retrograde urethrography and pyelography. In up to 50% of patients with vesicoenteric fistula, conventional diagnostic methods fail. Uro-radiological and endoscopic methods are unreliable and symptoms are often nonspecific [9]. In these conditions radionuclide renography can be very useful [10]. Correspondence
