[Results of radical surgery for renal cancer in adults].

For thirteen years, between 1963 and 1976, 120/139 patients with renal cancer were operated. 45 were stage I, 20 were stage II, 45 were stage III and 12 were stage IV (Robson's classification). Of the 45 stage III cancers, 13 had lymphatic invasion and 37 had venous invasion ranging from microscopic stages to invasion of the inferior vena cava. Treatment included: preoperative teleirradiation with cobalt most often a single dose of 500 rads on the day before the operation. Wide excision with primary ligation of the vascular pedicle and node dissection via a lumbar abdominal transperitoneal route remaining the minimum strictly necessary. Sequential monthly chemotherapy over two years of Vincristine and CCNU (chloroethyl cyclo hexylnitroso urea). Postoperative mortality was considerable (14%) but involved patients with advanced cancers, poor general condition (o% stage I, 10% stage II, 22% stage III and 40% stage IV). The long range survival remains excellent in spite of the postoperative losses: 65 p. cent 5 years all stages. However, stage determines the prognosis: 85 p. cent 5 year survival stage I and II and 53 p. cent 5 year survival stage III. Severe affection of the general state of the patient carries a very poor prognosis. Fever does not indicate a worse value except in stage III tumors. In stages I and II it can have value in the paraneoplastic syndrome (terme non familier). The authors, uncertain of the efficacity of preoperative radiotherapy and postoperative chemotherapy, concluded that wide excision with node dissection is the proper fundamental treatment of renal cancer in the adult.

[Concerning 490 renal transplants in the rat, Technical study (author's transl)].

The authors carried out 490 renal transplants in the rat, in order to train two laboratory technicians with no previous surgical competence, in this microsurgery. The different techniques of vascular and urinary anastomoses are looked at with their advantages and disadvantages. Two years were necessary in order to obtain a percentage of immediate success of 75 per cent. But, secondary infections and mainly urinary complications in this experiment, prevent obtaining more than 50 per cent of graft which could be exploited on a long term basis, which limits the scientific value of the method.

[Trial of a synthetic absorbable suture, Polyglactin 910, in 100 urologic patients].

The authors studied the clinical tolerance of Polyglactine 910 (Vicryl) in 100 patients operated upon for urological disorders. The operations were mostly for ureterovesical reimplantations to treat reflux, pyelocaliceal kidney stones and ureteral calculi, and prostatic adenomectomy. The suture appears to be solid, and the knots do not loosen. It slides badly however and is not easy to manipulate. When used to close cavity walls this solid suture did not cause a higher percentage of abscess than catgut, when used to suture the urinary excretory tract the authors observed, in one case only, multiple calcification around the ureterovesical suture points and those used to close the bladder. The suture is not suitable for vaginal repair operations during the surgical treatment of incontinence. The authors conclude by defining the properties of a suture they would like to see become available: one which has the same solidity, is easier to manipulate, slides more easily, and, above all, has a different texture: a monofilament rather than a braided suture.

[Reno-colic fistula, spontaneous rupture of the ureter, triple urter: ureterocoele: an unusual combination (author's transl)].

The authors report a case which is exceptional both on the basis of the association of malformations present as well as the presenting complications. Right triple ureter with ectopic implantation. Spontaneous fistulisation into the colon of a supernumerary pelvis. Rupture of a megaureter into the retroperitoneal space, the initial episode. Finally, double ureter on the left with ureterocoele. The difficulty of precise diagnosis before operation is emphasised. The latter did not permit immediate complete assessment of the lesions, the discovery and treatment of which required several operations.
