BACKGROUND The differentiation of the nature of a fluid collection as a complication of kidney transplantation is important for management and treatment planning. Early and delayed radionuclide renography can play an important role in the evaluation of a urine leak. However, it is sometimes limited in the evaluation of the exact location and extent of a urine leak. CASE PRESENTATION A 71-year...

OBJECTIVE The objective of this study was to compare 2 diuretic renography procedures: F-15 versus F+10(sp) for diagnosis of obstructive uropathy in adults. METHODS Thirty-six patients with unilateral or bilateral hydronephrosis had 2 consecutive Tc-MAG3 diuretic renograms within 7 days, using the widely used procedure F-15 in supine position, and a new seated-position procedure whereby the p...

Infantile hydronephrosis detected by ultrasonography poses a clinical dilemma on how to treat the condition. This article reports a retrospective study to evaluate infantile hydronephrosis due to suspected ureteropelvic junction (UPJ) obstruction by means of standardized diuretic renography and to speculate its usefulness for quantitative assessment and management of this condition. Between Nov...

A 47-year-old Hispanic woman developed a chronically obstructed left kidney, due to a long-segment ureteric stricture deemed not amenable to reimplantation, following left ovarian cyst excision in 2004. Therefore, a ureteral stent requiring exchange every 3 months was necessary, due to hydronephrosis, recurrent urosepsis, chronic pain, and a poor quality of life. Her medical history was complic...

OBJECTIVES To assess the feasibility and results of the endoscopic treatment of vesicoureteral reflux (VUR) after a failed ureteral reimplantation. METHODS From January 1996 to October 2006, 28 patients underwent endoscopic treatment for VUR grade II to V persisting after open ureteral reimplantation. VUR was bilateral in 11 patients, for a total of 39 ureteral units (UU) treated. The endosco...

Purpose: Controversies persist on pyeloplasty follow-up, and the aim of this study was to assess the differences and interpretations in results of postoperative ultrasonography and diuretic renograms. Materials and Methods: The study population consisted of 46 patients who underwent pyeloplasty between 1997 and 2003. The average patient age was 7.0 months (range, 2-36 months). Serial changes in...

BACKGROUND Scintigraphic image analysis of 99mTc-mertiatide (Mag-3, mercaptoacetyltriglycine) clearance provides the determination of the blood flow, the tubular transit time and the excretion as well from both kidneys. Radiopharmaceutical routine recommends a radiochemical purity control before administration of the product to a patient. The main objective of this study is to develop a Mag-3 l...

OBJECTIVES This study was done to evaluate the feasibility and efficacy of beta-radiation therapy with a rhenium-188-mercaptoacetyltriglycine ((188)Re-MAG(3))-filled balloon after rotational atherectomy for diffuse in-stent restenosis (ISR). BACKGROUND Rotational atherectomy has been shown to be safe and efficient for the treatment of ISR, but the recurrence rate is still high. Intracoronary ...

Material and methods: 125 patients (IDDM:10, NIDM:115), including 62 men, ages 18-84 years, were studied. In all cases GF (Cr 51 EDTA), ERPF (I-hippuran), kidney split function (obtained from the mTc-MAG3 renogram) and basal serum creatinine (SC) were evaluated at the beginning of the study and patients were clinically followed up for 5 years by SC. Ultrasound and/or intravenous digital angiogr...
