Summary
A forgotten surgical dressing in an 11-year-old boy's bladder mimicked a bladder stone. This unusual foreign body, undetected for eight years, highlights diagnostic challenges in pediatric urology.
Area of Science:
- Urology
- Pediatric Surgery
- Medical Imaging
Background:
- Foreign bodies in the urinary bladder are uncommon in children.
- Recurrent bladder stones can present with similar symptoms, complicating diagnosis.
Observation:
- An 11-year-old boy presented with symptoms suggestive of recurrent bladder stones.
- Ultrasound initially suspected a bladder stone.
- Open surgery revealed a retained surgical dressing from a prior operation eight years earlier.
Findings:
- The foreign body was a surgical dressing, overlooked for eight years.
- The patient experienced no significant clinical symptoms or infectious complications during this period.
- Diagnosis was delayed due to the typical presentation of bladder stones.
Implications:
- This case underscores the importance of considering retained foreign objects in the differential diagnosis of pediatric bladder conditions.
- It highlights potential diagnostic delays when clinical presentation is misleading.
- The long-term asymptomatic presence of a foreign body raises questions about host response and surveillance methods.

3.2K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

01:30Types of Building Stone
404
Building stones, essential materials for construction, are extracted from natural rock deposits and processed into specific forms and dimensions suitable for various building applications. These stones are broadly classified into three types based on their geological formation: igneous, sedimentary, and metamorphic.
Igneous rocks are formed from the solidification of magma or lava. An example is granite, known for its durability and resistance to weathering, making it ideal for parts of...

01:15Quarrying of Stone

Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

01:29Stone Masonry
445
Stone masonry is a construction technique that uses individual stones to build structures and can be categorized into two main types: rubble and ashlar. Rubble masonry uses uneven, naturally shaped stones such as river rocks or fragments from quarries. This method often requires the mason to select and possibly shape each stone to fit the designated space, ensuring a proper build, even with irregular stone sizes and shapes. Ashlar masonry, on the other hand, employs uniformly cut stones that...
