Objectives: To evaluate the long‐term functional outcomes of various types of orthotopic neobladder (NB). Methods: Eighty‐nine patients who underwent orthotopic NB reconstruction after radical cystectomy and were followed for at least 60 months after surgery were included in this retrospective study. The types of NB in this series were: modified Studer type, Hautmann type, Mainz type, Goldwasser type and modified Reddy type in 36, 9, 15, 10 and 19 patients, respectively. Results: Sixty‐seven (75.3%) patients could void spontaneously, 15 (16.8%) voided with clean intermittent catheterization (CIC) assistance and seven (7.9%) with CIC alone. After excluding the seven voiding with CIC alone, daytime and night‐time continence was achieved in 63 and 50 of the remaining 82 patients, respectively. In addition, the proportion of daytime continence in the modified Studer group was significantly greater than that in the Mainz group, whereas there was no significant difference in the proportion of night‐time continence among these groups. Uroflow examination indicated that despite the lack of significant differences in the maximal flow rates and the voided volumes, the post‐void residual in the modified Reddy group was significantly smaller than that in the modified Studer group. Blood gas analysis in the 82 patients showed that there were no significant differences in the pH, bicarbonate, chloride and base excess among these groups. Conclusions: Orthotopic NB created with intestinal segments generally has acceptable functional outcomes on long term follow up. These outcomes differ according to the type of NB. To define the optimal procedure for NB reconstruction, it is necessary to understand the long‐term functional prospects, on which the subjective success of NB creation is based.
