ABSTRACT

A congenital solitary kidney with multiple renal arteries is a rare congenital abnormality that can occur in the presence of multiple other anomalies. We describe an atypical case of a right congenital solitary kidney with three renal arteries (RA) one main RA and two additional renal arteries in a 75-year-old woman with uterine didelphys. The main RA had an intraluminal diameter larger than the diameter of the additional renal arteries (AdRAs) at the origin (0.53 cm for the main RA; 0.49 cm and 0.32 cm for the two AdRAs). Both the AdRAs had a greater length than the main RA (3.51 cm for the main RA; 3.70 cm and 4.77 cm for the two AdRAs). The calculated volume of the kidney was 283 cm³, while the volume of the renal parenchyma was 258 cm³. Knowledge of this variant is extremely important in clinical practice as it has been found to be associated with proteinuria, hypertension and renal insufficiency.
