Nevertheless, obstruction rarely can occur without hydronephrosis, when the ureter and renal pelvis are encased in a fibrotic process and unable to expand. In contrast, mild dilation of the collecting system of no functional significance is not unusual. Even obvious hydronephrosis in some cases may not be associated with functional obstruction [70]. Diuresis renography is helpful when the funct...

PURPOSE The objectives of the study were to use the International Atomic Energy Agency (IAEA) software package for the analysis of scintigraphic renal dynamic studies to obtain values of curve parameters and excretory parameters in children with hydronephrosis and to validate the reliability of these numerical outputs by comparing with values established by consensus reports. PATIENTS AND MET...

In renovascular hypertension adaptive mechanisms in the poststenotic kidney are a probable cause of the 20 to 25% false-negative findings during rapid sequence urography or [123I]o-iodohippurate renography. We blocked the renin-angiotensin system in an effort to increase the yield of these diagnostic procedures. Chronically instrumented, salt-depleted conscious dogs were used in which a light (...

many of injured children will require surgical treatment with involvement of the anesthesiologist. the anesthesia providers may have to take care of pediatric patients on following occasions: 1- initial stabilization in the emergency department 2- providing sedation and monitoring for imaging 3- preoperative management of emergent surgical procedures such as laparotomy or craniotomy 4- manageme...

conclusions sever thrombocytopenia and bleeding may be the presentation of brucellosis. case presentation we report on an eight-year-old boy who presented epistaxis and gum bleeding. the physical examination revealed petechiae, purpura, ecchymosis, and cervical while inguinal lymphadenopathy and splenomegaly were noted. brucella agglutinin titer was positive. after five days of specific therapy...

objective(s): appendicitis remains the most common condition in the pediatric population requiring emergency abdominal operation. management of acute simple appendicitis is well described but controversy remains as to the optimal treatment of complicated appendicitis. common complications of acute appendicitis include: localized peritonitis and abscess formation, flegmon and general peritonitis...
