Sodium hyaluronate in treatment of diffuse nephrogenic adenoma of the bladder in a child.

Nephrogenic adenoma is a rare, benign lesion of the bladder, occurring as an epithelial response to chronic infection or trauma, probably arising from nephrogenic metaplasia. In contrast to nephrogenic adenomas in adults, who present with this tumor in the entire ureteral tract, it has been observed exclusively in the bladder of children thus far. We report and discuss here the case of a 12-year-old boy with diffuse calculus-producing nephrogenic adenoma successfully treated with sodium hyaluronate.

The use of the Limberg skin flap for closure of large lumbosacral myelomeningoceles.

Closure of the skin defect in myelomeningocele repair is an essential step that determines the quality of the surgical result. In large myelomeningoceles, however, adequate skin coverage may not be accomplished by direct closure or skin undermining. In such cases, the skin defect is best repaired using flaps.

[Antibiotic prophylaxys in pediatric surgery of genito-urinary abnormalities].

Ninety-two patients in the age range of 2,5 and 16 years with hypospadias (28 cases), vescicorenal reflux (22 cases), hydronephrosis (16 cases) and a series of other congenital genitourinary abnormalities underwent one or more surgical interventions performed by an unique surgeon at the department of Pediatric Surgery, S. Bortolo Hospital, Vicenza. The more frequently performed interventions were the plastic of the urethra (28 pts, 30,4%), that of the pyeloureteral joint (15 pts, 16,3%) and the modelling and the reimplantation of the ureter/ureters (12 pts, 13%).
