Infant Feeding tube is universally used in Paediatric Patients for many diagnostic as well as therapeutic purposes. Intravesical knotting of IFT is rare but having significant morbidity. We here present such a rare case report in 6 month old patient treated endoscopically. Sometimes it is very difficult to remove knotting with various techniques discussed later, but it may cause more trauma to urethra. There are only few reported cases worldwide about it in few journals. But Endoscopic removal being safe among all. In such Urological Emergency, always early Identification is most important to prevent further complications. As neonate and infant’s urethra is small compared to the available smallest Foley catheter (8Fr), a 5 Fr and 8 Fr feeding tubes are practical alternatives to drain urine from the bladder. Intravesical catheter knotting of small feeding tubes placed as urinary diversion from the bladder is rare. The first case of catheter knotting in a pediatric patient was reported in 1976.
