Common Objects and Foreign Bodies Removed by Doctors
Emergency physicians frequently remove swallowed or embedded foreign objects from patients. In the United States, poison control centers handle over one million cases of foreign body ingestion annually, with children under six representing the largest group. Common items include coins, button batteries, and small toys, which can cause serious injury if not extracted quickly. Hospitals use endoscopes and specialized instruments to retrieve these objects safely from the esophagus, stomach, or airway.

Another common category involves sharp or pointed objects that penetrate the skin or deeper tissues. Emergency departments regularly treat patients with embedded fish bones, glass shards, metal fragments, and wood splinters. The World Health Organization reports that injuries from sharp objects account for a significant share of emergency visits worldwide. Doctors use imaging tools like X-rays and CT scans to locate these items before performing minor surgical extraction. Proper removal reduces the risk of infection, nerve damage, and long-term complications.
Medical Devices and Implants Extracted During Procedures
Surgeons routinely remove medical devices that have fulfilled their purpose or caused complications. Joint replacements, such as hip and knee implants, may require revision surgery after years of wear. The American Academy of Orthopaedic Surgeons notes that hundreds of thousands of revision procedures occur globally each year. During these operations, doctors extract worn-out prosthetics and replace them with new components. Infection, loosening, and implant failure are the primary reasons for removal.
Cardiac devices like pacemakers and implantable cardioverter-defibrillators are also removed when they malfunction, become infected, or need replacement. The Heart Rhythm Society reports that device infections occur in a small but significant percentage of implantations, requiring full extraction of the leads and generator. Surgeons use specialized techniques to free the device from scar tissue and blood vessels. In some cases, patients receive a new device immediately after the old one is taken out.
Stents, Catheters, and Other Temporary Implants
Doctors also remove temporary implants such as urinary catheters, central venous lines, and vascular stents. Urinary catheters are among the most commonly inserted and removed devices in hospitals, with guidelines emphasizing short-term use to prevent infections. Central lines, used for delivering medication or monitoring heart function, are extracted once treatment ends. Endovascular specialists remove stents from blood vessels when they are no longer needed or if blockages recur. The Society for Vascular Surgery provides protocols for safe extraction of these devices.
Tumors, Stones, and Biological Material Surgically Extracted
Oncological surgery focuses on removing tumors and cancerous tissue from the body. The American Cancer Society reports that surgery remains one of the most common treatments for many types of cancer, with millions of procedures performed worldwide each year. Surgeons extract malignant masses along with a margin of healthy tissue to ensure complete removal. Lymph nodes are also often pulled out and examined to determine whether the disease has spread.
Kidney stones and gallstones are another category of material doctors routinely extract. The National Institute of Diabetes and Digestive and Kidney Diseases states that kidney stones affect about one in ten people at some point in their lives. Urologists use procedures like lithotripsy and ureteroscopy to break up and remove stones from the urinary tract. Similarly, gallbladder removal, or cholecystectomy, is one of the most common surgeries performed globally, with over 700,000 procedures done annually in the United States alone, according to the American College of Surgeons at https://www.facs.org/.
