[Computed x-ray tomography in the detection of venous extension in renal cancer].

With reference to eleven cases of renal cancer with involvement of the inferior vena cava, CT semeiology of this venous complication is detailed. Furthermore, the authors suggest that the images are capable of a pathological interpretation which may indicate whether the obstruction is caused by the tumor or a thrombus. Lastly, the value and limitations of CT scan for detecting caval obstructions associated with renal cancer are analyzed.

[Computed tomography in renal trauma (author's transl)].

On the basis of a series of 25 cases of closed recent trauma of the kidney examined by scanner, the authors analyzed the information provided by the method and its correspondence with the various lesions encountered. In the course of this study, the scanner appeared to be the method of investigation which, at the present time, offers the best information concerning the severity of parenchymatous damage, as well as the size, nature and course of the perirenal blood or urine collections. Such data being fundamental to therapeutic decisions, the place of the scanner is essential in the evaluation of renal trauma, and, in severe forms, should be performed immediately after the irreplaceable I.V. urography performed as an emergency.

[The technique of ureteric advancement in vesico-ureteric reflux (author's transl)].

The authors, anxious about the crossed position of the ureteric meatuses after transverse submucosal advancement of the ureters, prefer descending submucosal advancement. They emphasise the widely open nature of the hiatus of penetration of the ureter into the bladder. Tightening of this orifice, distal to the orifice left free for the penetration of the ureter, participates in elongation backwards of the muscular layer upon which the submucosal advancement will take place. If necessary, if the trigone is too short, the vesical muscularis layer is slit in a proximal direction, uretero-vesical penetration withdrawn by an equal amount and suture of the muscular breach behand the ureter elongates a submucosal course which, without the use of this technique, would be too short. The authors have collected a series of 63 ureters. No stenosis, 3 residual reflux and at the time of follow up cystoscopy where applicable, the new meatus is easy to locate and to catheterise.
