Left kidney measures 5.4 x 2.9 cm and shows homogeneous parenchymal echogenicity with smooth outlines. Right kidney is not visualized at its expected normal position in the right renal fossa as well as in the remaining abdominopelvic cavity.

Scan shows well-outlined left kidney with good cortical tracer uptake. No functioning renal tissue is noted in the right renal area or anywhere else in the abdomen to suggest ectopic kidney.
Case Discussion
Sonographic and DMSA scan findings are consistent with unilateral renal agenesis which is an isolated finding in this asymptomatic patient.
