Özet
Aim: Ureter or pelvicalyceal system is not be vizualized with 99mTechne-tium- dimercaptosuccinic acid (99mTc-DMSA) which is accumulated by renal cortex normally. In this study the cases whose ureters are visible were re-viewed with 99mTc-DMSA scintigraphy. Material and Method: 18 patients (5 females, 13 males) with median age 3.5 years (min 2 months-max 18 years) were included in this study. Twenty ureters and/or pelvis of 18 patients were visible in 99mTc-DMSA scintigraphy. In two patients’s both ureters were visible. Vesicoureteral reflux (VUR) grade, 99mTc-DMSA uptake, renal size, status of pelvicalyceal system, urea, creatinine levels were evaluated in all patients. Results: Three of the visible ureters were actually due to pelvicali-ectasis. These pelvicaliectasic patients were excluded from the study. In the evaluation of the remaining 17 ureters of patients, congenital megaureter was present in three patients. Grade 3 VUR was detected in three patients, grade 4 was in three patients. VUR is seen as grade fıve in eight kidneys of seven patients because one of these patients has bilateral vizualized ureter. Discussion: In patients with congenital megaureter and VUR, ureters can be visible with 99mTc-DMSA scintigraphy and further imaging modalities are recommended for these patients.
