UNESPECTED COMPLICATION OF TIP URETHROPLASTY: THE DIVERTICULUM OF NEO-URETHRA

Surgical or conservative treatment of congenital hydronephrosis. Ten years' experience

Controversy exists concerning the ideal management of hydronephrosis diagnosed in the perinatal period. Different opinions depend on the absence of an accurate tool and of well-defined cut-off values for each test. For these reasons we retrospectively evaluated our management protocol.Two-hundred and seventy-two patients with single system hydronephrosis were evaluated. Patients with bilateral hydronephrosis or with other renal or ureteral abnormalities were excluded. Diagnosis and grading of hydronephrosis were done by ultrasound. Before 1995, grade II or greater hydronephrosis was also evaluated with diuretic intravenous urography, but in cases studied afterwards, a functional evaluation …

[Recent advances on retroperitoneal neuroblastoma]

Neuroblastoma, a malignant tumor of infancy and childhood, has some very interesting peculiars: good prognosis, even with disseminated disease, propensity to occasionally undergo spontaneous regression, its ability to undergo spontaneous or induced differentiation to a benign ganglioneuroma. Neuroblastoma may originate anywhere along the sympathetic nervous system chain. The most common site of primary tumor is, however, within the abdomen either in the adrenal gland or in a paraspinal ganglions. A great deal of progress has been made in advancing the knowledge of human neuroblastoma at the cellular and molecular viewpoint. The genetic predisposition to develop the tumor is clarified, a spe…

Multicenter Italian survey for varicocele treatment in pediatric age.

Fertility problems will arise in about 20% of adolescents with varicocele. (level of evidence: 1). The recommended indication criteria for varicocelectomy in children and adolescents are the following: varicocele associated with a small testis, additional testicular condition affecting fertility, bilateral palpable varicocele, pathological sperm quality (in adolescents older than16 years of age), varicocele associated with a supranormal response to LHRH stimulation test, symptomatic varicocele. Repair of a large varicocele physically or psychologically causing discomfort may be also considered.The aim of this multicenter study is to evaluate the management and treatment of varicocele in dif…

Polycystic ovary and gonadoblastoma in Turner's syndrome.

Turner's syndrome (TS) is characterized by typical facial features, short stature, hypergonadotropic hypogonadism, streak gonads, infertility, hearth and kidney malformations. Typical karyotype is 45,X0; however, 6% of TS have mosaic patterns including Y chromosome or fragments of Y. This karyotype is a risk factor of developing a dysgerminoma in dysgenic gonads. Furthermore, rare cases of polycystic ovary are described in young-adult patients with TS. We describe the clinical case of a 12-year-old girl with TS treated with GH who showed a good response to treatment. She developed an ovary with histological polycystic pattern and a contralateral gonadoblastoma in the streak gonad. Laparosco…
