BACKGROUND Conventional X-ray urography is one of the basic imaging techniques in urinary tract diseases in children. CT urography (CTU) employing standard Filtered Back Projection (FBP) reconstruction algorithms is connected with higher radiation dose. Advanced iterative reconstruction techniques enable lowering the radiation dose to the level comparable with conventional X-ray urography with ...

IF~ ~~' Pyelograms from two identical twins. (a) Case 1, showing left chronic pyelonephritis; renal outlines have been pencilled in for clarity. (b) Case 2, showing normal appearances apart from a minor degree of duplex bilaterally. Case reports Case 1-This patient was investigated at the age of 18 for recurrent urinary infection. She had been aware of symptoms only for the preceding few months...

OBJECTIVE To assess multidetector-row computed tomographic (MDCT) urography for detection of recurrence of bladder tumor after transurethral resection (TUR), and to assess significance of the MDCT findings like urothelial enhancement or thickening as a recurrence. METHODS A total of 216 MDCT urography examinations were performed for 100 patients undergoing follow-up after TURs were reviewed b...

PURPOSE To assess the effect of diuretic administration on the image quality of excretory magnetic resonance urography (MRU) obtained following intravenous hydration, and to determine whether intravenous hydration alone is sufficient to produce diagnostic quality studies of nondilated upper tracts. MATERIALS AND METHODS A total of 22 patients with nondilated upper tracts were evaluated with c...

BACKGROUND Prune Belly Syndrome (PBS) is a rare entity, usually found in male neonates. It comprises complex urinary tract anomalies, bilateral undescended testis and absence of anterior abdominal wall muscles. Patients with unilateral abdominal wall deficiency, unilateral undescended testis and female neonates with abdominal wall laxity are classified as Pseudo Prune Belly syndrome (PPBS). Rep...

AIM Introduction and assessment of an obstruction score in patients with obstructive uropathy, based on a diuresis renography time-activity curve. METHODS Twenty-eight adults with unilateral pelviureteric junction obstruction were assessed by ultrasound scan, furosemide-enhanced intravenous urography and modified (F-15) 99mTc-DTPA diuresis renography. Renal unit drainage pattern was assessed ...
