We experienced transurethral teflon paste injection for 12 refluxing ureters of 7 patients with neurogenic bladder dysfunction. Preoperative assessment of cystometry showed hypoactive bladder function with normal bladder compliance in 4 patients, and low compliance bladder (&lt; 10 ml/cmH2O) in 1. Voiding cystography revealed grade 1 reflux in 2 ureters, grade 2 in 3, grade 3 in 2, grade 4 in 2, and grade 5 in 2. One ureter did not show reflux. Zero point two to 1.6 ml of teflon paste was injected on each ureter under cystoscopic observation. These patients were followed for a mean of 25.1 months. Reflux disappeared immediately after the first operations in all patients, however recurrence was observed in 2 ureters, in which improvement of reflux (grade 5 to 2) was achieved in 1 ureter but no improvement (grade 2 to 2) in another. Pyelonephritis was not encountered in any patients after injection. No complication was observed through the follow up period. In conclusion, we advocate that endoscopic teflon paste injection is a useful alternative to ureteroneocystostomy in the treatment of reflux in patients with neurogenic bladder dysfunction.
