title: A rare pediatric case of grossly dilated ureter presenting as abdominal mass.
abstract: Renal masses account for 55% of cases presenting as palpable abdominal mass in children.[1] An eight year male presented with palpable abdominal mass and pain. The patient underwent renal dynamic scan, which raised possibility of left duplex kidney with non-functioning moiety, as the size of left kidney was smaller than seen on Ultrasonography (USG). Magnetic resonance (MR)urography confirmed the findings with patient undergoing left hemi-nephrectomy and is doing well. In case of discrepancy in size of kidney on USG and renal scan, duplex kidney should be considered as differential, other causes being, renal cyst, benign/malignant mass and renal calculi. Gross hydro-ureter presenting as palpable abdominal mass is very rare with few reported cases.[234].
