Diagnosis and conservative treatment of tubercular rectoprostatic fistula

To present our experience with three cases of rectoprostatic fistula with special emphasis on diagnosis and conservative management.

Three middle-aged men presented to us differently. All had spontaneous rectoprostatic fistulas. Biopsy showed tuberculosis though three consecutive urine samples for acid-fast bacilli were negative. None of the patients were immunocompromised. Their upper tracts were normal and all had a past history of pulmonary tuberculosis. They were started on antitubercular drugs and urinary diversion with or without faecal diversion.

All fistulae healed completely within 6 weeks of starting antitubercular treatment. One patient healed with bladder neck stenosis that required bladder neck incision. Voiding was normal on 1-year follow-up.

Spontaneous tubercular rectoprostatic fistulae are rare. There should be a strong clinical suspicion in endemic areas. Prostatic biopsy proves the diagnosis. Conservative management with antitubercular drugs and urinary diversion with or without faecal diversion has a high success rate and should be the first line of treatment even if urine is negative for acid-fast bacilli.
