RESUMO
Dilation of the ureter with a balloon catheter, 20 cm. long and 6 mm. in diameter, passed over a guide wire introduced into the ureter in a retrograde or antegrade fashion has been followed by prompt painless passage of calculi as large as 6 mm. in diameter in 3 patients. Limited radiographic evaluation has revealed no significant sequelae. Our limited experience indicates that it is a safe and expedient method to facilitate passage of ureteral and renal calculi.

We have reported two unusual cases of osteoid osteoma in small bones of the hand and foot. The roentgenographic appearance of a radiolucent area with a sclerotic rim in these regions and in the proper clinical setting must raise the possibility of osteoid osteoma. Computerized tomography can accurately demonstrate the highly vascular nidus.

Oleothorax as therapy for pulmonary tuberculosis was discontinued some 35 years ago. An oleothorax may expand and cause respiratory distress. Additional complications include bronchopleural fistula and cutaneous fistula. Computed tomography has not previously been used to evaluate oleothorax. This case report describes the use of computed tomography in a patient with a symptomatic oleothorax.

Esophageal dilatation is a safe and effective method for treating most esophageal strictures. Balloon dilatation is primarily used in those strictures in which conventional techniques were initially unsuccessful. We have successfully treated 13 patients with severe esophageal strictures of both benign and malignant etiologies. The patients subjectively felt better and weight gain was uniform. The patients were able to maintain adequate patency of the esophagus with bougie and self-dilatation. The length of follow-up ranged from 2 to 30 months. The various techniques used for balloon dilatation of esophageal strictures are presented. No serious complications were encountered. Dilatation by balloon catheter appears to be a safe method to dilate severe strictures and provides maximum patient benefit with minimal trauma and morbidity.
