[Epidemiology of tumors of the testis in Indre-et-Loire from 1978 to 1987].

All the testicular tumors found among the inhabitants of the Indre-et-Loire department between 1978 and 1987 were reviewed. There was a total of 122 tumors, i.e. a direct standardised incidence rate of 4.55/100,000. The incidence increased over the years 1978-1982, with an abrupt decrease at 50% in 1983 and the increase since then has been minimal. There was an excessive morbidity rate of 22% for patients living in an urban environment. There was no preferential side for the tumor. The histological types of the tumors permit to distinguish three types of populations: non seminiferous germ cell tumors (51.3%) at the age of 30 years; seminoma (41.3%) at the age of 40 years and lymphoma (7.4%) at the age of 74 years. An indirect standardisation revealed an excessive rate of 22% for the socioprofessional category of employers and a rate of 28% for artisan, business men and company directors. The study confirms the known notions about the age and the histologic distribution of testicular tumors. The highest incidence rate of all the French departments, the drop in the rate of this growth curve in 1983 and the over representation of the employee category appear to be the most specific notions in the Indre-et-Loire department.

[Ureterovesical reimplantation after failure of endoscopic treatment of reflux by Teflon injection. Apropos of 4 cases].

In a homogeneous series of 54 children (94 ureteric units) treated endoscopically for vesicorenal reflux, 19 patients (24 ureters) presented with recurrent reflux after 3 months. Four of them (6 ureteric units) underwent a secondary Cohen's antireflux plasty. In the light of these 4 cases, the authors consider that the submucosal injection of Teflon paste does not modify the immediate postoperative course of anti-reflux plasty. This constitutes another element in the discussion of the justification of this type of treatment.

[Renal leiomyoma. Apropos of a case].

Leiomyoma of the kidney is a rare tumor, for which little investigational imaging data is available, and which is poorly characterized by histological methods. We are here concerned with one case that benefitted from an extensive radiological workup, and we provide a comparison with other cases mentioned in the literature.

[Ureteral lithiasis: excision by ureteroscopy].

The authors report the first 6 cases in the world of removal of ureteric stones under visual control with the aid of a rigid ureteroscope . In 5 of the 6 cases, the authors were able to extract the stone endoscopically. The only failure was a case in which the stone was too large for the Dormia basket. The only source of difficulty was passing the ureteric meatus. A very small meatotomy may be required. Only the future will tell whether this results in reflux.

[Recto-sigmoid carcinoma after uretero-sigmoidostomy. One case, with a review of the literature (author's transl)].

A case of recto-sigmoid adenocarcinoma, developing 25 years after bilateral uretero-sigmo dostomy for extrophia vesicae in a 29 year old man. A study of the literature emphasises the long delay before its appearance, the gastrointestinal nature of the tumour and its grave prognosis. The pathogenesis of this lesion is unknown at present, and consideration should be given to the effects of urine on the digestive mucosa and the role of a possible inflammatory granuloma, but also the possibility of a urinary tract origin, despite the apparent histological contradiction.

[Xanthic lithiasis in the child. A study of one case. Review of the literature (author's transl)].

Seeking medical help because of an acute urinary retention, a 3-year-old child showed at intravenous urography (IVU) multiple radiotransparent lithiases. Hypouricemia suggested a diagnosis of xanthuria. The problems of this condition due to a congenital deficiency in xanthine oxydase are studied in a review of the literature. 56 xanthic lithiases have been published and since the work of Dent and Philpot, 28 xanthinurias have been reported.
