Chest radiographs show dextrocardia (A). Abnormal placement of stomach and liver (B). Computed tomography demonstrating a 78 x 50 mm diverticulum communicating with the bladder (C). Computed tomography demonstrating dilated hydronephrosis in the upper segment of the right-side ureteral (D).

Chest radiographs revealed dextrocardia (Figure 1A), and computed tomography and ultrasonography confirmed the diagnosis of SIT (Figure 1B). Pelvic computed tomography showed cystic low-density lesions on the right side of the bladder that communicated with the bladder cavity (Figure 1C), approximately 78 mm x 50 mm in size, accompanied by compression of the right pelvic segment of the ureter and dilatation of the upper segment (Figure 1D), showing the characteristics of bladder diverticulum.
The protuberant diverticulum (arrow head) located in the right side of the bladder (A). The sigmoid colon located on the right side of the abdominal cavity (B). The narrow diverticulum orifice (arrow head) (C). Suture the bladder under the guidance of balloon (D).

After visualizing the protuberant bladder diverticulum, the peritoneum was cut open with a median incision to expose the diverticulum fully (Figure 2A). Due to the mirror location of the organs, the sigmoid colon on the right side of the bladder caused the operating space to be squeezed (Figure 2B). Next, we dissociated the diverticulum completely along the surface, cut the bladder at the upper edge of the diverticulum, absorbed the urine, and resected the diverticulum circumferentially along the diverticulum orifice (Figure 2C). Under the guidance of the balloon, the bladder incision was sutured and closed continuously with a 2-0 inverted thorn suture (Figure 2D).
