Nephrobronchial fistula - a case report.

We report the case of a 58-year-old woman with a hydronephrotic left kidney who presented with a 4-month history of anorexia, weight loss and intermittent left loin pain associated with cloudy urine. Her urine grew lactose fermenting coliforms, and was treated with antibiotics. A computerized axial tomography scan (CT scan) was equivocal and she underwent retrograde ureteric stenting, which drained a pyonephrosis. She went on to develop a chest infection due to a lung abscess. A CT scan revealed a left perinephric collection extending across the diaphragm into the lower lobe of the left lung. She responded to antibiotics and awaits a nephrectomy.
