detrusor myectomy
Surgical removal or incision of detrusor muscle fibers to reduce bladder pressure and improve compliance.
Full Definition
Detrusor myectomy is a surgical procedure involving the removal or division of portions of the detrusor muscle to reduce bladder pressure and improve bladder compliance in patients with neurogenic bladder dysfunction. This technique is often performed as part of bladder augmentation procedures or as a standalone intervention to prevent upper urinary tract deterioration. The procedure can be performed as autoaugmentation (where only muscle is removed, leaving mucosa intact) or in conjunction with enterocystoplasty. Detrusor myectomy helps create a low-pressure bladder reservoir while preserving bladder capacity and function.
Usage
Usage note: Distinguish from complete cystectomy; this preserves bladder mucosa.
