Experience with various types of orthotopic neobladder in Japanese men: long-term follow-up.
BACKGROUND
The objective of this study was to review the long-term outcomes of orthotopic neobladder (NB) creation.


METHODS
This study included 235 Japanese men who underwent NB reconstruction after radical cystectomy and were followed for at least 3 years. The types of NB used in this series were Studer, Reddy, Hautmann and Mainz NB in 136, 51, 32 and 16, respectively.


RESULTS
Early and late complications occurred in 70 and 33 men, respectively. Of the 235 men, 210 could void spontaneously, and day- and nighttime continence were achieved in 189 and 149, respectively. The mean maximal flow rate, voided volume and post-void residual were 15.9 ml/s, 209.6 and 38.0 ml, respectively. SF-36 survey for postoperative quality of life showed no significant differences in 7 of the 8 scale scores between the 235 men and an age-matched control population in Japan. The 5-year overall and cancer-specific survival rates were 71.2 and 75.7%, respectively. There were no significant differences in any parameters examined among the four groups except for post-void residual, which was significantly smaller in the Reddy group than in the other three groups.


CONCLUSIONS
The orthotopic NB could generally provide satisfactory outcomes on long-term follow-up, irrespective of the types of NB.
