Urethral catheterization with 5 or 8F feeding tubes in 5 boys was complicated by stochastic knotting within the bladder thereby impeding removal. The common factor in these patients was insertion of excessive length within the bladder. Percutaneous endoscopic retrieval was done successfully in 1 child. This technique may avoid urethral trauma associated with catheter removal, particularly in younger boys.
