[Dilatation of the urethra by inflatable balloon catheter].

An inflatable balloon catheter of the Gruntzig type was used to dilate the urethra of 25 patients. The procedure involves atraumatic catheterization by a vascular catheter under televised urethroscopy, followed by introduction on a flexible guide of the balloon catheter which is then inflated. The stenosis is visible on the balloon and the rapidity with which it "yields" can readily be appreciated. Control of dilatation is effected by voiding urethrography. This method entails much less discomfort than conventional urethral dilatation. No complication was observed in this series. Stenosis recurred in 3 patients who subsequently underwent a second balloon dilatation.

[Percutaneous renal angioplasty].

Renal angioplasty was performed in twenty hypertensive patients, and good immediate results were obtained in 18 cases. One unsuccessful result was due to insufficient dilatation of a stenosed renal artery, and another from an accident during dissection of the aortic wall in contact with the renal ostium. Repeated dilatation was necessary in two cases following recurrence of stenosis. A high percentage improvement in the hypertension was obtained: 12 cases recovered and there was marked improvement in 4 other patients, treatment being effective, therefore, in 16 of the 20 patients operated upon. The published literature is reviewed, and emphasis placed on the need for treatment by surgeons experienced in angiography examinations, in close collaboration with the medical and surgical team, the later being ready to intervene if the slightest complication of a surgical nature develops.

[Azygography in pre-operative investigation of cancer of the esophagus : a report on 24 cases (author's transl)].

The value of azygography for detecting extension of cancer of the middle third of the esophagus was assessed in 24 patients. The examination was conducted using the retrograde approach, and results were compared with those obtained by the esophagogram and on tracheobronchial fibroscopy. Compression of the azygos vein is a good indicator of the size of the tumor, which can also be evaluated from esophageal transit examinations. The vein can be invaded or even thrombosed due to severe regional spread but this does not mean that excision of the tumor is impossible. The results of azygography alone, therefore, are not a valid reason for contra-indicating esophagectomy. In case of doubt, tracheobronchial fibroscopy appears to be more suitable for deciding whether the tumor is operable, but azygography can assist in making this decision.
