title: Foley catheter entrapment resulting from the formation of a true knot in a female infant: sonographic findings.
abstract: One of the rarest complications of bladder Foley catheter insertion is knotting of the catheter. We present a case of Foley entrapment secondary to formation of a true knot at the proximal end of the catheter in a 6-month-old female infant who was referred to our center for voiding cystourethrograthy. Sonography of the bladder revealed the knotted catheter in the urinary bladder.
