title: Nephrobronchial fistula. Complication of perinephric abscess secondary to ureteral obstruction and pyonephrosis.
abstract: A case of nephrolithiasis complicated by obstruction leading to pyonephrosis, perinephric abscess, and nephrobronchial fistula is presented. The patient was treated successfully by nephrectomy and drainage of the subphrenic space and the pleural cavity. Nephrobronchial fistula, while a rare complication of perinephric abscess, should be considered when a patient presents with perirenal suppurative process and chest x-ray findings consistent with pleural effusion or pulmonary infiltrates.
