A plastic tube self-inserted into the urethra by an 11-year-old boy mimicked nephritis symptoms. Removal of the bladder foreign body resolved urinary abnormalities, highlighting the importance of considering self-inserted objects in pediatric urinary issues.
Area of Science:
- Pediatric Urology
- Nephrology
Background:
- Self-inserted foreign bodies in the pediatric bladder via the urethra can cause urinary symptoms.
- Common symptoms include urinary tract infection, dysuria, abdominal pain, and hematuria.
Observation:
- An 11-year-old boy presented with microscopic hematuria, proteinuria, and leukocyturia.
- Progressive proteinuria and elevated antistreptolysin titre initially suggested glomerulonephritis.
- Ultrasound revealed echogenic material in the bladder; pelvic X-ray showed a 30 cm tube.
Findings:
- The patient admitted to inserting a plastic tube into his urethra two years prior.
- Cystoscopic removal of the foreign body was successful.
- Post-removal, hematuria, leukocyturia, and proteinuria resolved within four weeks.
Implications:
- Foreign bodies in the bladder can present with symptoms mimicking nephritis.
- This case underscores the need for thorough investigation, including imaging, in pediatric urinary abnormalities.
- Considering self-inserted foreign bodies is crucial for accurate diagnosis and treatment in children.
