[Perineal wound with urethral lesion in man. Two cases].

The author reports two cases of perineal wounds with section of the membranous urethra, one operated upon as a delayed emergency (36 hours) and the other as an emergency via a double hypogastric and perineal approach which permitted the opening of the bladder, anterograde catheterisation of the posterior urethra, liberation of the ends of the urethra and their preparation, mobilisation of the anterior urethra and finally end-to-end suture. Both patients seen with a follow-up of 6 months and one year had an excellent mictional result and preservation of erection. The author emphasises the following: --the need for confirming integrity of the bladder by I.V.U.; --the possibility of operating as a delayed emergency after packing of the wound, under cover of bladder drainage via a suprapubic catheter; --the need for a double hypogastric and perineal approach for lesions of the posterior urethra; --the usefulness of urethral catheter for 5 days and drainage of the urine by cystostomy for 3 to 4 weeks. Neither of the patients required secondary dilatation (at least within the limits of the period of postoperative follow-up).

[Carcinoma affecting a single kidney. Conservative surgery. One case (author's transl)].

On the basis of a case of partial nephrectomy of a single functioning kidney performed with immediate success in a 77-year-old woman, the author reviews the main data from the literature concerning this particular treatment of carcinoma of the kidney. In the great majority of cases the carcinoma required partial nephrectomy only because the affected kidney was single. Operative mortality was low : 2.6 %. Three year survival is 61 % of cases and it is important to note that terminal renal failure and recurrences in the remaining portion of the kidney are rare. Metastases represent the chief cause of death. Survivals ranging from 6 to 14 years have been reported. When the fact that the kidney is single is not because of nephrectomy for a carcinoma, the prognosis after partial nephrectomy is the same as that after wide excision for carcinoma (in patients with both kidneys). When the opposite kidney had been the site of a carcinoma and even more so in the presence of metastases, the prognosis becomes far less good. With a single kidney, the development of a carcinoma does not necessarily imply the need for total excision of the kidney followed by intermittent haemodialysis. A partial nephrectomy is worth the attempt when it appears to be reasonable. A number of particular technical features are emphasised : - the need for prior arteriography which defines the respective topography of the tumour and the renal vessels, - the safety of temporary clamping of the renal artery when the kidney is made hypothermic by cooling using ice piled up in contact with the kidney, - the possibility of performing such an excision in situ via an appropriate surgical approach.

Cardiac catheterization by percutaneous femoral venous approach in infants weighing less than 5 kg: observations in 97 cases.

The technique of cardiac catheterization after percutaneous introduction of a catheter can now be accomplished in neonates thanks to the refinement of the equipment and to the physicians' experience. In 100 catheterizations performed in infants of less than 5 kg, the new technique was utilized 97 times. Thanks to the utilization of introducers it permits Rashkind atrioseptostomy. Its main advantage is the preservation of venous integrity and this allows repeat investigations through the same route.

Transposition of the great arteries. New technique for anatomical correction.

We describe a new technique for the correction of transposition of the great arteries by "detransposition". An aortopulmonary window is created and a patch placed over this and the coronary ostia so that the coronary arteries arisen from the new aorta. Thus, direct surgery on the coronary arteries is avoided with all the complications which may result from this in neonates and infants. A 4.2 kg infant, with transposition and ventricular septal defect, was successfully operated on using this technique. We discuss the indications for this type of operation and conclude that, until we have more experience, it should be used only in children with a left ventricular pressure at least half systemic.

Intrarenal teratoma in a newborn child.

A case of intrarenal teratoma in a newborn child is reported. The scarcity as well as the clinical and radiological signs of this lesion are emphasized and the difficulties to distinguish it from a nephroblastoma are analyzed. Solid intrarenal tumours in the infant and the newborn child are in nearly all cases nephroblastomas. All other types of solid tumours (benign or malignant) are exceptional. This induces us to report the present case.

[Use of a membrane oxygenator in extracorporeal circulation in the child. Preliminary conclusions].

The comparison of two types of oxygenators, the bubble and membrane oxygenator, in cardiac surgery under ECC, in infants. The results were not subjected to a statistical study. However, it seems that the membrane oxygenator enables one to obtain a satisfactory hematosis in a simpler fashion (the addition of CO2 being avoided) than with the bubble oxygenator and leads to less hemolysis than the latter. In the cases of closed circuit ECC with recirculation, the use of the membrane oxygenator also gives greater security of manipulation of the blood mass.
