abstract background: screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (apn). diuretic tc-99m mercaptoacetyltriglycine (mag3) scintigraphy with zero time injection of furosemide (mag3-f0) was observed to display focal parenchymal disorders. the advantages of mag3 include: lower radiation dose and short duration of the test. the aim of this stu...

endourologic pyeloplasty is being a substitute of open pyeloplasty in management of ureteropelvic junction obstruction. this procedure can be done in different manners like balloon dilation, cold knife and electrosurgical endoureterotomy, accucise and lasers.a 47 year old woman referred with history of previous open pyeloplasty. hydronephrosis of right kidney with unremarkable t ½ was found in ...

FOR SEVERAL years an active program in human organ transplantation has been conducted at our institution (1-3), and since March 1962, 214 patients have received renal transplants. Two thirds of these transplanted kidneys are still functioning and most of these patients are living nearly normal lives. In addition, limited success has been achieved in liver transplantation (4-6). Of 14 recipients...

BACKGROUND This retrospective study was designed to determine the efficacy of broad-spectrum antibacterials combined with percutaneous renal drainage in the treatment of emphysematous pyelonephritis (EPN). METHODS From July 1992 to September 2002, 10 patients (nine females and one male) with EPN were managed at our institution. All patients had diabetes and presented with fever and chills, fl...

The radioactive iodine has been used with great value as a diagnostic and therapeutic method in patients with differentiated thyroid carcinoma previously submitted to total thyroidectomy. False-positive whole-body scans may occur due to misinterpretation of the physiologic distribution of the radioisotope or lack of knowledge on the existence of other pathologies that could eventually present r...

Navicular stress fractures mainly occur in sprinting and push-off athletes. Numerous predisposing factors have been implicated in their development. Within a six-week interval in the summer of 2009, twin brothers, both elite track and field athletes, presented to us with medial foot pain. Plain radiographs were negative but a radioisotope bone scan and CT scan revealed an incomplete navicular f...

We report on two children aged 2 and 6 years, who underwent laparoscopic ipsilateral ureteroureterostomy for their renal duplex anomalies. Both patients had complete duplex and were investigated by ultrasound, micturating cystourethrogram, magnetic resonance urography, and radioisotope scan. One patient had high-grade vesicoureteral reflux to lower moiety complicated with recurrent urinary trac...

Alimentary tract duplications are rare congenital anomalies. The presentation depends on their anatomical location, size and other characteristics. The most common variety is small bowel cystic duplication. We report a case of an eight years old girl who presented with recurrent abdominal pain and melena. Radioisotope technetium scan showed increased uptake of tracer in right lower abdomen and ...

Sources of error in the estimation of ventricular volume from CAT scans are discussed and the accuracy of the measurement assessed. Two methods of calculating ventricular volume from an intraventricular injection of radioisotope are described and compared. Finally, the CAT scan and isotope methods are compared and contrasted. The error associated with a single measurement of volume by any of th...
