[Replacement enterocystoplasty in man (except Hautmann): principles and technical considerations].
Orthotopic urinary reservoir using a bowel segment has become the most favoured form of diversion after radical cystectomy. Ideal neobladder has to (i) store the urine with a low pressure bladder substitute, (ii) protect the upper urinary tract and (iii) provide a better quality of life enabling volitional voiding. A lot of techniques have bee described to construct a reservoir, however, all of them are based on the principle of intestinal loop detubulation. Many intestinal segments have been used, but ileum seems to be preferred in Europe. The upper urinary tract is mainly protected by a low neobladder pressure, rather than an additional antireflux flap-valve-type implantation technique which may increase the risk of uretero-enteric stricture. No significant difference in functional outcome can be observed among the several techniques. In selected cases, orthotopic bladder replacement is well tolerated and feasible and appears to be the gold standard after cystectomy.
