Introduction: In paediatric practice, the underlying anatomical abnormalities of urinary tract need to be considered in recurrent urinary tract infection. Case Report: A 5 year old girl presented with recurrent urinary tract infection. Ultrasonography revealed rounded anechoic lesion at the vesicle base continuous with dilated tubular structure inferolaterally to the left side of bladder sugges...

OBJECTIVE This is a study concerning ureteroceles associated with a single collecting system of the involved kidney. METHODS Over an eight-year period 9 children (5 boys, 4 girls) had a ureterocele subtending a single collecting system, whereas 63 children had duplex ureteroceles. Malformations of other organ systems were present in only 1 patient. RESULTS Three patients have undergone surg...

OBJECTIVE To assess the results of an upper pole nephrectomy technique on 5 children. MATERIALS AND METHODS Upper pole nephrectomy was performed on 5 children, including 4 females and 1 male. Age ranged from 3 to 6 years old. The technique was performed without initial dissection of the renal pedicle. The upper pole is incised and removed. Upon its complete dissection, the segment that drains...

Mean flow predictions obtained from a host of turbulence models were found to be in poor agreement with recent direct numerical simulation results for turbulent flow distal to an idealized eccentric stenosis. Many of the widely used turbulence models, including a large eddy simulation model, were unable to accurately capture the poststenotic transition to turbulence. The results suggest that ef...
