The object of this study is to evaluate the functional and urodynamic characteristics of 16 patients who had undergone the Camey II orthotopic bladder replacement after radical cystoprostatectomy. Questionnaires regarding the voiding pattern and urinary continence were answered by 14 patients. Daytime continence was achieved in 13 of 14 patients (93%) at a mean interval of 3 months postoperatively. Eight patients (62%) attained their nighttime continence at an average interval of 10 months. Six of these 8 patients had to void to keep dry at night. Urodynamic studies were completed in 13 patients at an average of 11 months (range 6–23) postoperatively. Patients with nighttime continence had a significantly higher cystometric filling capacity (323 vs. 196 ml, p < 0.001), lower basal pouch pressure (24.5 vs. 35.2 cm water, p = 0.04), lower maximal voiding pressure (62.1 vs. 88.0 cm water, p = 0.01) and higher maximal urethral closure pressure (65.5 vs. 44.0 cm water p = 0.03). There is no significant difference among the parameters of the age at operation, the amount of residual urine and the functional profile length between these two groups of patients. The antireflux procedure was successful in 11 of 12 patients (92%). We conclude that the Camey II operation could fulfill all the criteria of ideal bladder substitution with adequate volume, low resting pressure, satisfactory continence rate and antireflux characteristic.
