Combination of urolithiasis and anomaly: Bifid ureter with fusion in the intramural part

Kidney and upper urinary tract anomalies account for 23% of all birth defects. Partial duplication is slightly more prevalent than complete, 70% and 30%, respectively. A very low fusion of ureters, i.e., in the intramural part, is a rarer case. As a result, the joint section is very short (<1 cm) and may be invisible for radiological diagnosis. This case shows a rare variation of incomplete bifid ureter coupled with urolithiasis, which should be taken into account by the physician when determining urolithiasis treatment.
