[Rare testicular tumors. Apropos of 15 cases].

In a series of 141 patients treated over the last ten years for testicular tumour, 15 presented lesions considered to be rare: 9 Leydig cell tumours, 3 epidermoid cysts, 1 leiomyoma, 1 primary testicular lymphoma and one testicular localisation of a known leukaemia. The clinical, endocrine and histological features of these different tumours are reviewed on the basis of the present series and a wider discussion of other rare testicular tumours. Leydig cell tumours, epidermoid cysts, mature benign teratomas and testicular lymphomas are the most frequent. Leiomyomas, metastatic tumours and connective tissue tumours are exceptional. Sertoli cell tumours are rare and are similar to Leydig cell tumours in that they raise problems concerning their possible endocrine activity and the evaluation of their malignant potential. The general therapeutic rule of radical orchidectomy for any testicular tumour is still valid.

[Neuroanatomical study of micturition].

There are three superimposed centres of micturition: the sacral spinal centre, which is the oldest centre controlled by the pontine centre situated in the brain stem, which in turn is under the control of multiple subconscious structures: cerebellum, striate nucleus, hypothalamus and conscious structures: limbic cortex, frontal ascending and parietal ascending circumduction. The nervous pathways consist of the classical spinal pathways as far as their point of emergence. The innervation involves 2 systems:--a supra-levator system consisting of the essentially sympathetic superior hypogastric plexus and the essentially parasympathetic inferior hypogastric plexus which innervates the seminal tract, the bladder and the prostatic urethra;--a infra-levator system consisting of the internal pudendal nerve which innervates the striated sphincter.

[Treatment of neoplastic thromboses of the inferior vena cava secondary to adenocarcinomas of the kidney. Study of 40 cases].

The extension of renal cell cancer into the vena cava is not inaccessible to treatment. In the absence of any other effective treatment, only surgical resection is able to provide a chance of long term survival. The authors report their experience of 40 cases, 24 of which underwent complete resection of their lesions. The survival rates in these cases were 47.6% at 1 year, 28.6% at 2 years, 15% at 3 years and 9.5% at 5 and 7 years. A selective approach to the right auricle was performed in three patients and the technique of this operation is outlined. The global mortality was 8.8%. The various technical possibilities and the prognostic factors are also reviewed.

[Responsibility of the left renal vein and inferior vena cava in certain cases of myelitis and syringomyelia. Value of ligation of the venous reno-spinal trunk. Apropos of 30 cases].

Certain diffuse forms of myelitis may be due to raised intra-spinal venous pressure resulting in veritable "varicose veins of the spinal cord". The origin of this increased pressure is often multifactorial, but may be due to venous reflux of blood from the left kidney into the intraspinal plexuses via the reno-spinal trunk. Ligation of this trunk results in a considerable and often complete improvement in the neurological syndrome. This operation was performed for the first time by our team in 1973 and since then has been successfully performed on 30 occasions for 21 cases of myelopathy and 9 cases of syringomyelia.

[Similar evolution, with cerebral metastases, of testicular cancers in 2 non-twin brothers].

The authors describe two cases of germinal carcinoma of the testis. The two patients were brothers, but not twins. The evolution of the disease was the same in both cases, with cerebral metastases. The etiology was not discovered but the localization of the metastases in the brain would seem due to the fact the antimitotic drugs used in therapy failed to cross the brain blood barrier.

[Ureteral metastasis of a prostatic cancer].

The authors report the case of a patient treated medically for prostatic cancer, who presented with a ureteric metastasis suggestive of a tumour of the excretory tract. Histological examination revealed that this lesion was actually a suspended metastasis of prostatic cancer.

[What should be done in the presence of isolated microscopic hematuria in man in the work environment?].

Microscopic haematuria was detected by the strip technique in 3.5% (normal: 1.8%) of 2100 men over 40 years of age, systematically examined at their place of work. Thirty-two agreed to undergo further investigations. Eight (25%) were found to have a urinary tract disease: kidney stones (2), prostatic adenoma (2), vesical diverticulum (1) and, notably, vesical tumour (2). Intravenous urography detected these abnormalities in 75% of the cases but missed the vesical tumours which were detected only at cystoscopy, urine cytology being also negative. The data obtained by cystoscopy were confirmed by vesical echography in 1 case. Thus, we believe that in the presence of even a single episode of microscopic haematuria in a man over 40, an intravenous urography should be performed. If the results are normal, and if the subject is a smoker or presents with an occupational or familial risk of cancer, this examination should be followed by cytology and vesical echography. If both are negative, then cystoscopy is necessary.

[Topographic anatomy of the caliceal stem: the colonic risk].

Body-section roentgenograms were taken of seventy five patients examined for non-urological complaints. These were studied and the axes of the ventral and dorsal calices were measure. The axis of the ventral calix passes through the left or right colon. The axis of the dorsal calix follows the avascular line and passes to the lateral border of the paravertebral muscles, avoiding the left and right colon. These anatomical data confirm that the dorsal calix is the route of choice in the percutaneous approach to the kidney.

[Urologic manifestations of aortocaval fistulas].

The authors report two cases of aortocaval fistula, resulting from the rupture of an abdominal aneurysm, and revealed by lumbar pains and hematuria. In both cases, the left kidney was mute, and was possibly responsible for the hematuria.
