Abstract

Duplication of the kidney and ureter is a relatively rare congenital malformation compared with other systemic malformations. It is even rarer for the duplicate to have stones inside; therefore, the present study reports the case of a patient with complete repetitive ureteral malformations combined with occult stones who showed marked improvement in symptoms and good recovery after surgical treatment. The patient received a timely diagnosis and achieved a good treatment outcome. The patient was satisfied with the treatment and had a good follow‑up. Early and accurate diagnosis and timely treatment are crucial for patients with recurrent ureteral malformations combined with occult stones, and can effectively improve patient prognosis.
