2122039 9307815 PCTABS00021 Methods and systems for treatment of vesicoureteral reflux are disclosed in which a detachable balloon catheter (28) is incorporated into an endoscopic instrument, such as a cystoscopic needle (26). The needle is directed through a cystoscope (12) and inserted into the subureteral region (44) of the refluxing ureter (42). A catheter or similar delivery device is inserted into the subureteral region (44), carrying a balloon (30). The balloon is then inflated, preferably filled with an inert biocompatible material, and then sealed. After inflation, the balloon is detached and left in the pocket such that the junction of the bladder (40) and ureter (42) is reconfigured to prevent reflux.
