USEFULNESS OF BLADDER AUTO-AUGMENTATION IN NUROGENIC BLADDER: A Case Report

Abstract

A 41-year-old male with myelomenigocele underwent a bladder auto-augmentation and endoscopic collagen injections. He has been performing self intermittent catheterization for 10 years but urinary incontinence remained unchanged. Futhermore, he suffered from recurrent pyelonephritis due to the left vesicoureteral reflux. A preoperative fluoroscopic urodynamic study showed a poorly compliant bladder with the maximal bladder capacity of 200ml at 60cmH₂O. The left vesicoureteral feflux was observed at 10cmH₂O. The low compliant bladder was treated with the bladder autoaugmentation and the left vesccoureteral reflux was treated with the endoscopic subureteral injection of collagen 5 months after the previous operation. A fluoroscopic urodynamic study 6 months postoperatively showed the increase of the maximal bladder capacity of 300ml at 18cmH₂O and the reflux disappeared completely. The endoscopic periurethral injections of collagen improved his persisting urinary incontinence.
In patient with neurogenic bladder having a lot of clinical problems, bladder auto-augmentation is less invasive and offers many advantages over enterocystoplasy.
