"A Boari bladder flap is one of the options for ureteric reimplantation when the diseased ureteric segment is long (e.g. more than 5 cm). It is useful in the management of lower ureteric strictures and can be performed as either an open or laparoscopic procedure. It involves tubularisation of a flap of bladder to extend from the bladder to the ureteral orifice. It is important for radiologists to be familiar with this procedure, especially in post-surgical image interpretation."
