[Transurethral Injection Using Deflux for Vesicoureteral Reflux in Three Adult Women with Frequent Febrile Urinary Tract Infections].

We report three patients with frequent febrile urinary tract infections (fUTI) who underwent transurethral injection therapy with Deflux for vesicoureteral reflux (VUR). The first case was in a 52-yearold woman who was initially diagnosed with right grade II and left grade I VUR at 18 years of age. She frequently experienced fUTI due to VUR. The second case was in a 29-year-old woman. At age 23,she was diagnosed with right grade III VUR when she developed fUTI. After that,she repeatedly developed fUTI. The third case was in a 40-year-old woman who had frequently experienced fUTI since 25 years of age and had gradually become antibiotics-resistant. She was diagnosed with right grade III VUR when she was referred to our hospital. No visible reflux was confirmed by postoperative voiding cystourethrography after the patients underwent transurethral injection using Deflux. One patient developed fUTI once after surgery,but there were no perioperative complications and no recurrences. Transurethral injection using Deflux for VUR might therefore be safe and effective for treating VUR in adult female patients.
