Is a closed bladder neck on preoperative videourodynamic studies an important factor for continence following augmentation ileocystoplasty in myelodysplastic patients?

Purpose: The aim of this study is to evaluate the importance of a closed bladder neck during videourodynamic (VUDE) studies in relation to urinary continence following augmentation ileocystoplasty in myelodysplastic patients. Materials and methods: We retrospectively reviewed the records of 24 myelodysplastic patients who underwent augmentation ileocystoplasty, using a standard technique. All patients had a closed bladder neck during preoperative VUDE studies. Their charts, imaging studies and VUDE data before and after surgery were analyzed. The mean follow-up after augmentation ileocystoplasty was 8.4 years. Results: The overall incidence of urinary incontinence following the augmentation ileocystoplasty was 12.5%. Continence was achieved in 21 of 24 (87.5%) patients without additional outlet procedures. No significant upper tract changes developed. A clinically apparent tethered cord significantly hindered the achievement of continence. No significant correlation was found between the other videourodynamic parameters and obtaining continence. Conclusions: Our study provides evidence that a coexisting cord tethering in this myelodysplastic group can affect bladder neck morphology and function, and subsequent continence.
