  • Title: Management of vesicoureteral reflux secondary to neurogenic bladder.
    Author: Morioka A, Miyano T, Ando K, Yamataka T, Lane GJ.
    Journal: Pediatr Surg Int; 1998 Oct; 13(8):584-6. PubMed ID: 9799381.
    Abstract:
    The authors encountered 108 cases of vesicoureteral reflex (VUR) in 231 cases of neurogenic bladder complicating spina bifida. Bladder compliance and percent volume (% vol.) were measured pre- and postoperatively and the patients were divided into four groups retrospectively according to the treatment. Ninety-five percent of low-grade VUR (grades I and II) disappeared spontaneously with conservative therapy or after augmentation cystoplasty without antireflux surgery; 92% of high-grade VUR (grade III or more) required ureteral reimplantation with or without bladder augmentation. Reflux did not recur in any case of ureteral reimplantation with bladder augmentation, however, it did recur in 20.4% of the cases of simple ureteral reimplantation without bladder augmentation. Percent volume and bladder compliance in cases of recurrence following simple ureteral reimplantation were significantly lower than in the successful cases. This study suggests that low-grade VUR can resolve spontaneously with conservative therapy or with a suitable maneuver to improve bladder compliance. High-grade reflux in cases of preserved bladder volume (% vol.>75%) and compliance (>7 ml/cmH2O) can be treated successfully with simple ureteral reimplantation, however, in cases of low volume (% vol.<60%) and low compliance (<4 ml/cmH2O), reimplantation with bladder augmentation is recommended.
