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...

A woman aged 31 had recurrent urinary tract infection with bloody urine. A series image of medullary sponge kidney presented by intravenous urography (IVU) was detected dynamically by retrograde pyelography (RP). Other than ultrasonography and IVU, RP is also a reliable method to detect medullary sponge kidney.

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 two-year-old, male, neutered, domestic shorthair cat was presented after suspected trauma. Diaphragmatic rupture with concomitant displacement of the right kidney into the thorax was diagnosed using ultrasound and intravenous urography. Avulsion of the renal pedicle and diaphragmatic rupture were confirmed and treated surgically with excellent outcome.

PURPOSE To evaluate several protocols for depiction of the urinary collecting system with multi-detector row computed tomographic (CT) urography. MATERIALS AND METHODS Fifty-one patients with hematuria or a suspicious renal mass underwent CT urography, during which thinly collimated (1-mm) pyelographic phase scanning was performed 8-10 minutes after contrast medium administration. Patients we...
