Endoscopic correction of vesicoureteral reflux in patients with neurogenic bladder dysfunction.

Transurethral injection of Teflon paste (TUI) was carried out in 24 ureters of 16 patients with vesicoureteral reflux (VUR) secondary to neurogenic bladder dysfunction at an age ranging from 4 to 77 years, and the results were compared with those of conventional open surgery. During the mean follow-up period of 20.1 months, reflux disappeared in 19 ureters (79%), so that the success rate of endoscopic operation was considered to be satisfactory as compared with that of conventional open surgery, in which reflux disappeared in 16 (80%) of 20 ureters in 16 patients with neurogenic bladder dysfunction at our department. No exacerbation of hydronephrosis was observed postoperatively, and no complication was noted. This procedure, which is minimally invasive and technically simple, may be regarded as the first choice for VUR secondary to neurogenic bladder dysfunction.
