Resumen

Following Bricker's^{7 Bricker E.M. Symposium on clinical surgery: Bladder substitution after pelvic evisceration Surg Clin North Am 1960 ; 30 : 1511

The ease of construction, the mobility and reliable vascular arcades of the small bowel mesentery, relative paucity of early complications with the use of silicone stents, and fewer electrolyte disturbances are major advantages. Concerns with late upper tract damage from reflux and urinary infections, however, and stomal complications led to interest in nonrefluxing diversions with colon and ileocolonic segments, and eventually continent reservoirs. One of the earliest continent ileal reservoirs was advanced by Camey,^{7 Camey M., LeDuc A. L'enterocystoplastie avec cystoprostatectomie totale pour cancer de la vessie Ann Urol 1979 ; 13 : 114

Camey's procedure, however, was troubled by nocturnal incontinence from the tubularized bowel contractions. The introduction of detubularization by using reconfigured bowel dramatically lowered intraluminal filling pressures and improved continence.^{20 Kock N.G.

The Kock pouch, initially devised for continent ileostomy, was popularized in the early 1980s as a urinary reservoir by Skinner, who added several revisions to minimize complications associated with the antirefluxing, continent intussuscepted nipples.^{23 Kock N.G., Nilson A.E., Nilsson L.O. , y al.

Neobladders were initially utilized in patients with no evidence of malignancy beyond the bladder neck, but recent experience with neobladders shows a decreased urethral recurrence rate in neobladder patients with prostatic urethral or stromal involvement compared with patients with a cutaneous stoma and defunctionalized urethra. Although this has been mostly limited to men, several recent studies have reported successful orthotopic neobladders in women by carefully preserving the external sphincter in the mid and distal urethra.^{40 Stein J.P., Stenzl A., Esrig D. , y al.
