[Diagnostic and therapeutic approach to the extension of kidney cancer to the vena cava].

In the light of their experience with 16 cases seen over 5 years, the authors analyze the diagnostic and therapeutic tools for assessment of the vena cava thrombi that complicate 5 to 10% of renal carcinomas. Cavography still plays a central part in the detection of vena cava lesions. Localization of the upper extremity of the thrombus is needed to decide upon the operative technique and can be achieved by free flow inferior cavography for free floating thrombi; for complete thrombi, the two most informative procedures appear to be echocardiography (to evaluate the right atrium and intrathoracic inferior vena cava) and inferior cavography by the superior route; it seems that computed tomography provides no additional information in the assessment of extensive spread to the inferior vena cava.

[Endometriosis and obstruction of the upper excretory pathway. Apropos of 2 cases].

The authors report two new cases of endometriosis of the ureter, one affecting the pelvic ureter as part of a locoregional disorder, and the other, more unusual, affecting the lumbar ureter and apparently isolated. Both patients were treated surgically: one with ureterovesical reimplantation in a psoic ureter, and the other by resection and anastomosis after ureterolysis, because the diagnosis was only made postoperatively on the basis of the anatomicopathological images. Details concerning this rare localization of endometriosis are given on the basis of a review of the literature.

[Prevention of post-operative infections in urologic surgery. Comparative study of cotrimoxazole and cefazolin].

The main point of this study resides in comparing the efficiency and the disadvantages of using cefazoline and cotrimoxazole in the prevention of post-surgery infections of the low urinary tract. 91 patients who were about to undergo urologic surgery were divided in three groups for randomisation. 31 patients received 500 mg of intramuscular cefazoline every eight hours, the day before surgery, the day of surgery and five days following surgery.
