[The megaureter-megabladder syndrome. Apropos of a case].

The authors report the observation of a five year old boy who presents recurrent urinary tract infections with infrequent voiding and without residual urine. Uroradiologic investigations show a megaureter-megabladder syndrome. Pathogenesis and management of this syndrome are then discussed.

Blind ureterocele.

Ureterocele without corresponding renal tissue (blind ureterocele) represents a very rare malformation which is of special interest for the understanding of the embryogenesis of this anomaly. Two cases, the first without corresponding kidney seen in an adult and the second in connection with a small multicystic kidney observed in a boy, are considered. In light of the observation of the disappearance of antenatally diagnosed multicystic kidney, these lesions are considered to represent two different stages of the same anomaly.

Queyrat's erythroplasia of the prepuce: a case-report.

A case of Queyrat's erythroplasia of the prepuce is reported. The Authors emphasize the precancerous role of the lesion because of its high frequency of malignant transformation. Local excision appears to be the only adequate form of treatment.

Leiomyosarcoma of the prostate in adults.

Three cases of prostatic leiomyosarcoma and a brief review of the literature are presented. The authors emphasize the differences in clinical features, management and prognosis between the sarcomas occurring in childhood and the rarest leiomyosarcoma of elderly patients.

[Neurogenic bladder caused by spinal cord traction].

A neurogenic bladder was the presenting syndrome in three cases of spinal cord traction. Of the typical symptomatic triad: neuro-orthopedic, cutaneous and urologic, the latter was of primary importance. Symptoms in the first case were incomplete bladder retention with distention of upper urinary tract, right-sided vesicorenal reflux and renal insufficiency.

Open instillation of formalin for cyclophosphamide-induced hemorrhagic cystitis in a child.

A child with massive hematuria, produced by cyclophosphamide-induced cystitis, was treated with open bladder instillation of formalin. To prevent vesicoureteral reflux, we inserted two Fogarty catheters. Intraoperative retrograde cystography was made to confirm that there was no reflux, extravasation or passage of contrast per urethra.

Upper urinary tract obstruction in children caused by Candida fungus balls.

2 children with upper urinary tract obstruction from Candida fungus balls are reported. A presumptive diagnosis, made on the basis of clinical and radiological findings, was confirmed by microscopic examination of urinary sediment. Medical treatment was successful in both patients.

[Alcoholic myopathy. Histochemical and ultrastructural study].

Muscles of alcoholic rats undergo histochemical and ultrastructural study. Significative alterations have not been found. The authors compare their experimental data with analogous human pathology, pointing out the possible biochemical and immunological differences.

Cervical uterine atresia with hematometra: a rare cause of urinary retention in a girl.

Atresia of the cervix is a rare congenital anomaly of the female genital system. We describe a girl with urinary retention caused by hematometra and other urinary malformations, for which prior operations had been performed.
