一位46歲男性膀胱轉型細胞癌患者接受了膀胱根除手術及被命名爲「Studer囊袋(Studer pouch)」的膀胱重建。當他接受鎝－99m-MDP全身骨骼掃描時發現右側骨盆腔有明顯的骨骼外放射活性聚集。這個發現被認爲是具有放射活性的尿液聚集於Studer囊袋。

The 46-year-old male was a victim of transitional cell carcinoma of urinary bladder. Radical cystectomy and a neobladder reconstruction, Studer pouch, were performed. The 99mTc-MDP whole-body bone scan after the operation showed significant accumulation of radiotracer in the right pelvis. The scintigraphic finding was thought to be stasis of radiolabeled urine in the Studer pouch.
