egrilerinden 1/2 Tmax degerini ve split fonksiyonlarini degerlendirdikleri calismalarinda T1/2 20 dakikanin uzerinde olanlari obstruktif hidronefroz olarak tanimlamislardir (17).
A Micturating Cystourethrogram and Diuretic renogram
was performed in all the cases with SFU 3/4.Four cases refused further evaluation.
The provision of nuclear medicine services in the region of murcia, for patients of the murcian health service, in a health center that has sufficient facilities and means to perform the following diagnostic tests: - thyroid scan, - bone scintigraphy in 3 phases, - 3-phase gammagraphy with iodine or gallium, - pulmonary scintigraphy ventilation, - pulmonary perfusion scintigraphy, - total body bone scan, - renogram
with captopril or furosemide, - lymphoscintigraphy, - sentinel node detection in the operating room.
[.sup.99m]Tc-DTPA can be an alternative for the calculation of relative renal function without a follow-up DMSA scan, particularly in subjects who demand renogram
curve and GFR computations (17).
The current imaging test of choice for the assessment of the function of a hydronephrotic kidney is the MAG3 diuretic renogram
, as it permits assessment of both the differential renal function (DRF) and the drainage time.
Initial delayed graft function was evident from low urine volumes and acute tubular necrosis (ATN) confirmed on 99mTc MAG-3 renogram
. Graft function gradually improved and the patient was discharged on day 17 postoperatively.
A DMSA (dimercaptosuccinic acid) scan showed 36% function of the right kidney and a MAG-3 (mercaptoacetyltriglycine) renogram
suggested moderate to severe right pelviureteric junction (PUJ) obstruction but with preserved renal function.
PTRA was indicated for hemodynamically significant RAS with either of the following: (1) peak systolic velocity [greater than or equal to] 1.8m/sec by RDU, (2) diameter or area stenosis rate [greater than or equal to] 75% by magnetic resonance imaging angiography, and (3) prolonged vascular, functional, and distribution phases by renogram
. Cases without viability of the affected kidneys (RI evaluated by RDU < 0.8 and/or low distribution of the affected kidney evaluated by renogram
) were excluded.
In a study where renal parenchymal thickness ratio is compared to Mag-3 Lasix renogram
, renal PW on CT scan was found to be significantly correlated to renogram
function (correlation coefficient of 0.48, p < 0.001).
documented a significant positive correlation between urinary [beta]2m and serum creatinine and a negative correlation with GFR estimated from the uptake phase of 99m technetium diethylenetriaminepentacetate renogram
(GFR-DTPA) and creatinine clearance .
Patient age, preoperative and postoperative length of follow-up, antero-posterior pelvic diameter (PD) measurement, findings on ultrasound (US), 99mTc-DMSA renal SPECT, diuretic renogram
(DTPA/MAG3) and vesico- cysto-urethrography (VCUG) as well as all relevant complications were recorded.
confirmed ureteral leak, which was repaired surgically.
