Introduction
Most congenital ureteral strictures occur at the ureteropelvic or ureterovesical junction in children. Mid‐ureteral stricture is very rare and can cause congenital hydronephrosis. Only a few studies have reported on coexisting mid‐ureteral stricture with ipsilateral atrophic kidney in young adults.
Case presentation
A 16‐year‐old girl presented with repeated urinary tract infection. Computed tomography revealed a right atrophic kidney and hydroureter. Retrograde pyelography showed a mid‐ureteral stricture. Laparoscopic nephroureterectomy was performed, and histological examination revealed mid‐ureteral stricture with hyperplasia of the fibrous connective tissue and an atrophic kidney.
Conclusion
Mid‐ureteral stricture in a young adult is extremely rare. Appropriate imaging studies including retrograde pyelography are necessary for accurate diagnosis of mid‐ureteral stricture.
