BACKGROUND Congenital mid-ureteral stricture is a rare malformation of the ureter leading to prenatal and neonatal hydronephrosis. Site characterization of the narrowing is important to optimize the surgical approach to the newborn affected by hydronephrosis. CASE PRESENTATION We report a female EM with a rare form of hydronephrosis, (i.e. mid-ureteral stricture) which was detected early duri...

BACKGROUND Open dismembered pyeloplasty remains the preferred surgical technique for ureteropelvic junction syndrome (UPJS) in most paediatric urology units. The authors present their experience of 230 patients and describe their form of presentation, treatment and early and long-term results. MATERIALS AND METHODS Retrospective analysis of clinical records of 230 patients submitted to dismem...

The main tool of radionuclide techniques applied to paediatric uro-nephrology is the quantitation of function, which is an information not easily obtained by other diagnostic modalities. The radiation burden is low. Drug sedation is only rarely needed, whatever the age of the patient. Accurate determination of glomerular filtration rate can be obtained by means of an intravenous injection of Cr...

This study was performed to evaluate the role of postnatal ultrasonography (US) in predicting the final diagnosis and need of surgery of antenatal hydronephrosis patients. One hundred and twenty six renal units (RUs) of 76 patients with diagnosis of antenatal hydronephrosis (ANH) were studied. An early postnatal US no later than the first week of life was requested. Voiding cystourethrography (...

BACKGROUND Bardet-Biedl syndrome (BBS) is a rare autosomal-recessive disorder characterized by abdominal obesity, mental retardation, dysmorphic extremities, retinal dystrophy, hypogonadism, and kidney structural abnormalities or functional impairment. It is now considered a significant cause of chronic and end-stage renal disease in children. To the best of our knowledge there have been no pre...

The aim of the study is identification of urinary tract infections (UTI) and urinary tract anomalies (UTA) already in the perinatal period. The authors attempted to prevent serious consequences of the above conditions in the examined children. Family history data, certain conditions in pregnancy and appertaining symptoms in children were elaborated to specify selective distinctive criteria for ...

The purpose of this study was to develop a method based on artificial neural networks for interpretation of captopril renography tests for the detection of renovascular hypertension caused by renal artery stenosis and to assess the value of different measurements from the test. A total of 250 99mTc-MAG3 captopril renography tests were used in the study. The material was collected from two diffe...

Tc-99m-EC is a new renal radiopharmaceutical introduced as an alternative for Tc-99m MAG3. Twenty-three normal volunteers and patients in different .stages of renal disease were evaluated with Te-99m EC and Tc-99m DTPA. The mean initial uptake of EC was significantly higher as compared to DTPA. There was a high correlation between rectangular and hand-drawn ROls for kidney and background,...
