[Cancer of schistosomiasis-infected bladders. Apropos of 6 cases].

It is a well known fact that patients with urinary schistosomiasis are at risk for carcinoma of the bladder. Although relatively few cases are seen in France. Among 130 patients with urinary schistosomiasis hospitalized in our department from April 1980 to December 1984, 6 cases of carcinoma of the bladder were diagnosed. Our series has a number of specific characteristics: patients are Black Africans, and the anatomoclinical characteristics of these tumors differ from those found in vesical tumors in Europeans free of schistosomiasis, with, apparently, a greater sensitivity to chemotherapy.

[Anatomical study of the verumontanum of the urethra].

Five samples of infra-montanal prostatic urethra, fixed in formalin and stored in liquid nitrogen at -30 degrees C were examined histologically. The results of this study demonstrated that muscle fibres of the striated sphincter extend as far as the level of the veru montanum. The proportion of rapid and slow striated fibres was identical. These striated fibres were mixed with smooth muscle fibres of the urethra. The density of innervation of this muscular tunic was found to increase closer to the striated sphincter; it is composed of equal numbers of adrenergic and cholinergic fibres.

[Development of the human prostate during the first stages of fetal life. Morphometric study].

The initial prostatic development was investigated here with morphometric methods. Five male human fetuses, ranging in crown-rump length from 50 to 92 mm (foetal age 9 to 12.5 weeks) were studied. The morphometric analysis underline the importance of the prostatic mesenchyme and the later growth of the epithelial buds. Some reconstructions showed a crescent-shaped disposition of the supra-deferentials buds, according to the actual hypothesis about a "preprostatic" zone.

[Real-time echography in the evaluation of the venous extension of cancer of the kidney. Prospective study of 50 cases].

Fifty patients with renal carcinoma were evaluated with real time ultrasonography: 15 tumors involved the renal vein (group Ia), 12 of them presented with caval tumor extension (group Ib); 35 tumors did not involve the renal veins (group II). In 3 cases, the renal vein could not be visualized. If the renal veins could be adequately delineated, evaluation of venous extension could be achieved in 100% cases (groups Ia and II). Nevertheless, caval tumor extension could be detected in only 70% cases (group Ib). This prospective study suggests that in the case of renal vein free of thrombus on ultrasonography, further investigations are not necessary to evaluate the venous extension of renal carcinoma. In case of inadequate delineation, or tumor involvement of the renal vein on ultrasonography, evaluation of inferior vena cava is mandatory, either by computed tomography, or inferior cavography.

[Pyelo-duodenal fistula complicating pyelonephritis].

The authors report a case of a pyeloduodenal fistula secondary to a gravidic pyelonephritis. The diagnosis was based on intravenous urography. The etiology was probably an unnoticed dysectasia of the pyelo-ureteral junction. The patient recovered following nephrectomy and duodenal suture. The authors conclude with a discussion of the diagnostic and prognostic interest of percutaneous nephrostomy in the management of this rare complaint.

[Accessory adrenals in the spermatic cord. Apropos of 2 cases].

The authors report two cases of ectopic adrenal glands situated in the spermatic cord and recall the embryological mechanisms for such a location. They stress the fact that the origin of the gonads is very close to that of the adrenal cortex. It is important to be aware of this abnormality, especially in cases in which all sources of adrenal cortical secretion need to be suppressed.

[Disseminated peritoneal leiomyomatosis associated with endometriosis. Apropos of a case].

A rare case of leiomyomatosis Peritonealis Disseminata (L.P.D.) associated with an Endometriosis is reported. A 40 years old non-gravid patient had a laparotomy for uterine fibromas. Multiple sub peritoneal nodules were found and a total hysterectomy with annexectomy was done with the diagnosis of peritoneal metastatic disease. The light and electron microscopy showed a benign multicentric proliferation of myofibroblasts and smooth muscles cells. The association with endometriosis suggests that L.P.D. must have a metaplastic origin, from subcoelomic mesenchymal cells, as speculated by previous authors.

A new member of the polyomavirus family: the hamster papovavirus. Complete nucleotide sequence and transformation properties.

The hamster papovavirus (HapV) is associated with multiple skin epitheliomas of the Syrian hamster. We have sequenced its genome. It is a double-stranded circular DNA of 5366 bp. The hypothetical genomic organization deduced from this nucleotide sequence is clearly of the polyoma type with the two strands coding in the opposite directions from a noncoding region that shows some of the features of a replication origin and a transcription control region. The amino acid sequences predicted from the open reading frames show an average of 50% homology with polyoma-coded polypeptides. The HapV is, after polyoma, the second example of a papovavirus coding for a middle T antigen. The cloned DNA can immortalize primary rat embryo cells and transform an established rat cell line. The viral DNA is stably integrated into the host genome.

Restriction endonuclease cleavage map of the DNA of hamster papovavirus.

A detailed restriction map of hamster papovavirus (HaPV)-DNA has been constructed on the basis of the complete nucleotide sequence of the viral genome. The HaPV DNA restriction map is totally divergent from those of all other recently known papovaviruses. This map will be useful for future functional studies of the HaPV genome.

[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.

[Percutaneous nephrostomy and its applications. Personal experience].

211 percutaneous nephrostomies (PCN) have been performed on 189 patients under combined fluoroscopic and reel time ultra-sound guidance. 4 major complications occurred with consisted in one hemorrhage and 3 septicemias. Indication of the PCN was diagnostic in 35 cases and therapeutic in 176 cases. Decompression of pyelo-caliceal system (89 cases) among with 72 in emergency, drying of an urinary fistula (8 cases), balloon dilatation of benign ureteral stenoses (18 cases) and treatment of 60 renal stones (3 dissolutions and 57 extractions). Results showed the drying of the fistula in all cases, the long term success of the balloon dilatation in 50% cases and 80% success rate of stone extraction.

[Hemostasis of the preprostatic veins in total cystoprostatectomy. Anatomical bases].

An anatomical study has enabled the authors to propose a diagrammatic description of pre-prostatic veins, the haemostasis of which is one of the difficult stages in total cystoprostatectomy for cancer. These veins are surrounded by the pubovesical ligaments but they are separated from the membranous urethra by a cleavage plane which can be used to control venous bleeding.

Anatomical bases of kidney transplantation in man.

Kidney transplantation is a well codified operation. The way to reduce surgical complications (urological and vascular) lies in a precise knowledge of the anatomy of the renal pedicle, as well as of the ureter and its vascularization. The choice of a site for implantation depends on anatomical arguments which aim at using a well vascularised ureter, and so a short one, and a renal pedicle without tension, with therefore a long or extended renal vein. A privileged site for transplantation is the right or left iliac fossa; transplantation in the lumbar fossa remains exceptional.

Anatomical basis of the surgical approach to the membranous urethra.

The pars membranacea is the short segment of the urethra traversing the floor of the perineum. The main anatomical obstacles encountered in the approach to the membranous urethra are the perineal body posteriorly, and the deep dorsal vein of the penis and preprostatic venous plexus, anteriorly. These obstacles must be borne in mind when performing a surgical approach to the membranous urethra. The perineal body is the main obstacle to the perineal approach and can be avoided by incision of the sagittal raphes (anobulbar and rectourethral raphes) posterior to it and up to the apex of the prostate. When the trans-symphysial or transpubic approach is used, detachment of the suspensory ligament and roots of the penis allows exposure of the preprostatic venous plexus whose inferior part lies over the membranous urethra.
