A case of spontaneous feeding tube knotting over a vesical calculus, in a 3 years child, is presented which had evaded clinical diagnosis and was discovered at open cystolithotomy. A vesical calculus with a firm simple knot of feeding tube over it and stuck at internal urethral meatus was found. Feeding tube was cut and cystolithotomy performed. Postoperative follow-up was without complication.
