Intravesical foreign bodies are an uncommon, but significant, cause of urologic consultation. We present 3 patients who all inserted magnetic beads per urethra into the urinary bladder, which subsequently became retained. Endoscopic attempts were unsuccessfully tried in the first 2 cases, necessitating open cystotomy to remove the beads. The third went straight to open removal. Given the failure of minimally invasive techniques, we believe that open removal should be the first-line treatment for these types of foreign bodies.
膀胱内异物是泌尿外科会诊中一种不常见但很重要的病因。我们报告3例患者，他们均经尿道将磁珠置入膀胱，随后磁珠滞留。前2例尝试内镜取出未成功，需行开放性膀胱切开术取出磁珠。第3例直接进行了开放性取出。鉴于微创技术失败，我们认为开放性取出应作为这类异物的一线治疗方法。
