Case (1) was a 14-year-old boy who presented with intermittent left lower back pain was noted to have left hydronephrosis with an intraureteral mass. Case (2) was a 15-year-old boy who had been complaining of intermittent left lower back pain since he was 10 years of age. MRI showed ureter wall irregularity. Both patients underwent laparoscopic pyeloplasty. Retrograde pyelography showed a filling defect in the upper urinary tract. The ureter containing the polyp was laparoscopically excised intact. The polyp in each of the patients was solitary, and histopathological analysis confirmed it to be a fibroepithelial polyp. For patients with hydronephrosis with recurrent lower back pain, ureteral polyps should be considered as a differential diagnosis. Most of the pediatric ureteral polyps were located near the uretropelvic junction, so that partial resection of the ureter with the stalk by pyeloplasty is often chosen. However, depending on the number or location of the polyps, it is necessary to consider another method, and that it is recommended to perform retrograde urography before the operation. In addition, laparoscopic surgery, which enables us to approach the lesion and zoom in, and thus not leave any residual lesion, is a wise choice.
