[Newborn infants diagnosed prenatally with uropathies].

UNLABELLED: A clinical study of 111 newborns (NB) with prenatal diagnosis (PD) of urinary tract pathology was performed. The weight and size at birth, physical examination, incidence of uropathies, associated malformations and postnatal diagnostic studies were analyzed. MATERIAL AND METHODS: All data corresponding to 111 neonates with PD of urinary tract pathology were submitted to the Student's t and Chi square tests and contingency tables. RESULTS: Uropathies were more frequent in male NB (69%) and on the left side (2/1). Pyelocaliceal dilatation (PCD) was present in 46% of the patients. The mean weight and size was normal. However, NB with PCD had a mean weight of 249 grams below that observed in the remaining group (p = 0.016). Thirteen newborns (12%) had associated anomalies. An abdominal mass was present in 17 neonates with obstructive uropathies (15%). Serum urea and creatinine were normal in 101 neonates (91%). SUMMARY: 1) PCD is the most frequent uropathy diagnosed prenatally. 2) The incidence of fetal uropathies, diagnosed prenatally, is higher in males. 3) The left side is more frequently involved. 4) The mean weight and size of NB with uropathies is normal. 5) The mean weight of NB with DCP is 249 grams lower than the rest of the group. 6) Serum urea and creatinine were found elevated only in severe bilateral obstructive uropathies.

Bilateral multifocal Wilms' tumor.

A three-year-old boy who presented with symptoms of peritonitis was found to have four Wilms' tumors affecting both kidneys. Individual enucleation of three tumors in the right kidney plus left lower nephrectomy were performed. Chemotherapy was administered for one year. The diagnosis of Wilms' tumor was confirmed on each specimen by the histologic studies. The child remains asymptomatic and developing normally six years after the initial surgical treatment. Bilateral partial nephrectomies is the most conservative of the surgical treatments available for bilateral Wilms' tumor.

[Fluid loss pressure in 45 children with congenital neurogenic bladder].

OBJECTIVE: This study analyzed the relation between leak point pressure (LPP) at first urodynamic evaluation and the status of the upper urinary tract (UUT) and renal reflux (RR). METHODS: The study comprised 45 myelodysplastic children, one week to 13 years of age; 19 (42%) were less than one year old. LPP was measured when liquid started to come out through the urethral meatus, around the 5-6 Fr catheter. UUT was evaluated by ultrasound and RR by voiding cystography. RESULTS: 19 children had LPP < 30 cm H2O; all cases had a normal UUT, although 5 (26%) had RR. Twenty-six cases (58%) had LPP > 30 cm H2O; 12 (46%) had abnormal UUT and 6 of these had RR; 7 cases had RR but normal UUT. The group with LPP > or = 30 cm H2O was analyzed according to LPP values. The UUT was abnormal in 31% of cases with LPP 30-60 cm H2O and 37% had RR; UUT was abnormal in 70% of cases with LPP > 60 cm H2O and 70% had RR. Of the 19 patients less than one year old 9 (47%) had LPP < 30 cm H2O, no patient had abnormal UUT and only two (22%) had RR; 10 cases had LPP > or = 30 cm H2O, 6 of these had abnormal UUT and 5 had RR. CONCLUSIONS: In this study UUT was normal when LPP was < 30 cm H2O. Renal impairment and RR increased with LPP. Urethral functional obstruction carries a worse prognosis of pediatric neurogenic bladder. In these cases clean intermittent catheterization is recommended, regardless of patient age and sex.
