OBJECTIVE To study the effects of a short ureter on renal function and histology in an orthotopic bladder substitution model using a long afferent limb, in a canine model. MATERIALS AND METHODS The study included nine adult mongrel dogs. A 40-cm segment of ileum was isolated, the distal half detubularized, configured into a U-shape and sutured to form a flat plate; this was then used to augme...

PURPOSE To determine the diagnostic value of magnetic resonance (MR) urography in children with urinary tract dilatation. MATERIALS AND METHODS Twenty-five children between the ages of 4 months and 13 years (19 males and 6 females, mean age 6.5 years) were evaluated with T2 weighted and contrast-enhanced T1 weighted MR sequences. Results were compared with findings obtained with ultrasonograp...

Hematuria, symptomatic and incidental, that involves more than three red blood cells per high-power field on two of three properly collected urinalysis specimens warrants some type of imaging to evaluate the upper tracts. Traditionally, excretory urography or the intravenous pyelogram has been the mainstay of the hematuria work-up, but computed tomography urography has more recently been recogn...

OBJECTIVE To evaluate the frequency of adverse events and possible risk factors after the administration of an intravenous contrast medium (CM), iobitridol, in a large multicentre postmarketing surveillance study. SUBJECTS AND METHODS A total of 49,975 patients undergoing intravenous urography were included in this study. A water-soluble, non-ionic CM (iobitridol, 1 ml/kg body weight) was adm...

OBJECTIVE The purpose of this study was to compare the cost-effectiveness of sonography and CT for the evaluation of renal masses discovered at excretory urography. MATERIALS AND METHODS The records of 225 patients with a renal mass shown by urography who then had either sonography or CT within 3 months were reviewed retrospectively. The number, location, and size of lesions; initial and subs...

BACKGROUND Klippel-Feil syndrome is defined as congenital fusion of two or more cervical vertebrae and is believed to result from faulty segmentation along the embryo's developing axis during weeks 3-8 of gestation. Persons with Klippel-Feil syndrome and cervical stenosis may be at increased risk for spinal cord injury after minor trauma as a result of hypermobility of the various cervical segm...

INTRODUCTION Distigmine, a long-acting anti-cholinesterase, is associated with side effects such as Parkinsonism, cholinergic crisis, and rhabdomyolysis. We report a spinal cord injury patient, who developed marked hydronephrosis and hydroureter after distigmine therapy, which led to a series of complications over subsequent years. CASE PRESENTATION A 38-year-old male developed T-9 paraplegia...

A 17 years unmarried female presented to Gastroenterology Department of our hospital for nonspecific symptoms of epigastric pain. The Ultrasonographic examination of the patient revealed triple kidney with horseshoe anomaly. She was then referred to us for further evaluation. We further proceed with Intravenous Urography (IVU) which demonstrated a bilateral duplex system in a asymmetrical horse...
