Spontaneous Multiple Knotting of a Feeding Tube Urinary Catheter in an Infant with Crouzon Syndrome: A Case Report.

Background and clinical significance: Catheter knotting is a rare but potentially serious complication of urethral catheterization in neonates and infants, particularly when feeding tubes are used due to small urethral caliber. Case Presentation: We report the case of a 6-month-old male infant with Crouzon syndrome who underwent cranioplasty. Intraoperatively, a 6 Fr feeding tube was inserted for bladder drainage. On postoperative day 6, resistance was encountered during catheter removal. Radiography revealed a double knot in the distal urethra and a single knot in the proximal urethra. The catheter was successfully removed surgically via cystotomy, and the infant recovered uneventfully with normal voiding function.

Conclusions

This case demonstrates the exceptional occurrence of simultaneous double and single knots in a urinary catheter. Awareness of this rare complication, careful control of insertion length, and prompt intervention upon resistance are essential to prevent urethral trauma and ensure patient safety.
