cystoplasty

 [sis´to-plas″te]
plastic surgery of the bladder, usually referring to some type of augmentation cystoplasty.
augmentation cystoplasty enlargement of the bladder by grafting to it a detached segment of intestine (enterocystoplasty) or stomach (gastrocystoplasty). Called also bladder augmentation.
sigmoid cystoplasty augmentation cystoplasty using an isolated segment of the sigmoid colon for the graft.

cystoplasty

Any structural surgical procedure performed on the urinary bladder. Clam augmentation cystoplasty is a complex surgical procedure used to treat the condition of unstable or irritable (hyper-reflexive) bladder. The organ is split into two and then reconstituted using a patch of gut taken from the small intestine. This greatly weakens bladder function and prevents full voiding but is effective in controlling involuntary urination.

The choice of a suitable scaffold for cell delivery and /or the ingrowths of bladder wall components are recognized as one of the key factors that determine regenerative capacities and graft function in augmentation cystoplasty. The engineered scaffold must provide optimal structural integrity to withstand in-vivo requirements and appropriate regulation of cell behaviour (5).
The most common surgical option, augmentation cystoplasty, involves placing a "patch" derived from an individual's bowel over a part of the diseased organ in order to increase its size.
