Duplex right kidney with bifid ureter, appearing to unite at the level of the pelvic brim. Ureteric calculus in the lower moiety ureter, just prior to the apparent union, and results in moderate right lower moiety hydronephrosis and adjacent fat stranding.
Renal calculi in the right upper moiety with dilatation of the calyces proximally indicating some obstruction. Non- obstructive right lower moiety calculus. Normal appearing left kidney with two calculi in the left lower pole.
Case Discussion
Duplex kidneys are the result of abnormal fusion and can result in a wide range of abnormalities. Duplicated ureters are more common in symptomatic patients.
