“…Also, the capacity increase after detrusor myotomy is smaller than after myectomy. No dierence in capacity increase between the two techniques was found in rabbits, 22 but in this study all animals developed mucosal ®brosis.…”

Bladder autoaugmentation in adult patients with neurogenic voiding dysfunction

et al. 1997

Bladder autoaugmentation oers an alternative to enterocystoplasties for patients with low capacity high pressure bladders caused by non-malignant pathology. In particular for patients with neuropathic hyperre¯exive bladders, refractory to less invasive therapy, bladder autoaugmentation will attain comparable results with less impact on life quality compared to other bladder augmentation procedures. The procedure does not preclude later enterocystoplasty or deaerentations. Over the last 7 years, 50 patients were treated by this method, some of them for other than neurogenic voiding dysfunction. Substantial increase of bladder capacity and compliance resulted, at the cost of increased residual urine and the need for intermittent catheterisation in most patients. Some patients are able to perform complete voiding at will. The time lapse between surgery and functional rehabilitation of the bladder (substantial increase of capacity and detrusor compliance) cannot be predicted yet. In most patients this amelioration was observed 1 ± 6 months after surgery, but in some the eect was equivocal for a year or longer. Low-dose anticholinergics appear to speed up the therapeutic eect. One patient had enterocystoplasty and one deaerentation later, one had rupture of the bladder, probably from the use of an arti®cial sphincter, and two are rated as failures because of psychogenic bladder-centred problems. Bladder autoaugmentation is a favourable treatment for patients who are motivated to wait possibly longer for functional changes to occur and are willing to perform intermittent catheterisation afterwards.

“…15,16,22 The reason may be found in technical variations, as discussed above, or in interspecies dierences. No post-operative extravasation 11,23 has been noted, probably because we have full access to the mucosa and ligate any perforations immediately.…”

“…This is the reason that Snow and Cartwright [11] described intermittent bladder filling or a minimal blad der tension during the time the catheter is in place. In the rabbit model of Johnson et al [12] the surface area of the autoaugmentation was decreased by 51.8% by 12 weeks postoperatively and there was a thickening of the autoaug mentation site by 500%. Even omental interposition to prevent healing or fibrotic contraction over the scar does not prevent this [13], Another surgical technique, vesicomyectomy, resulted in the same urodynamic, histologic, and radiographic findings as vesicomyotomy [12], Stöhr er et al [9] reported that patients who underwent vesicomyectomy without improvement had intraoperative com…”

“…Some authors have described only slight improvements in bladder capacity, whereas others have noted improvements in capacity with persistently high bladder pressures (70–72). In the series reported by Stothers et al (71) simple vesicomyotomy was performed in their patients after earlier experimental work had suggested detrusor excision offers no advantage over detrusor incision (73). That same experimental work has shown that histologically the autoaugmented area was characterized by a fibrous infiltrate with an increase in thickness of 500% in comparison to the thickness immediately after augmentation.…”

The Evolution of Bladder Augmentation: From Creating a Reservoir to Reconstituting an Organ

Bladder augmentation was first described in 1899. The goal at the time was to establish the ideal method to create a simple capacious reservoir for the safe storage of urine. That simple idea has over the last 100 years grown into one of the most dynamic areas in Pediatric Urology. Creative minds and hands from individuals in multiple disciplines have led us from creating a reservoir to the threshold of recreating a functional organ. In this review, we look at the historical evolution of bladder augmentation and how it exponentially grew in scope from those initial descriptions of intestinocystoplasty to the work being reported today in the field of tissue engineering.
