Self-knotting catheter post urethroplasty: a case report.

Intravesical catheter knotting is a rare and challenging complication. This case report aims to report the management of a self-knotted catheter following urethroplasty in a pediatric patient. We report a 6-year-old male patient, 14 days after urethroplasty, who complained of urinary retention and a stuck catheter. Abdominopelvic x-ray and urology ultrasonography showed a suspicion of material surrounding the catheter. Transcutaneous cystoscopy showed a knotting catheter. Removal of the tied catheter segment resulted in the successful removal of the urethral catheter. Even though knotting catheters is a rare complication, it is a potential cause of failed catheter removal.
