This study gives the urodynamic and functional results of orthotopic urinary diversions, with particular reference to the Camey II, Studer and VIP, used the most in our country. Data show that function is satisfactory, especially with regard to bladder voiding and daytime continence. Nocturnal continence, however, seems to be the weak point of the procedure. The differences between the various types of orthotopic reservoirs are also analysed.

Enlarging enterocystoplasty (EA) is widely used to restore bladder function in patients with neurologic bladder or severe fibrosis of the bladder wall. Results are excellent regarding the creation of a suitably sized and compliant reservoir, while voiding and urinary continence depend on the functional conditions of the original bladder. Intermittent catheterism (CI) or restoration of sphincteric function are often necessary. The indications, choice of intestinal segment, EA functional assessment criteria and results are discussed.
