Our extensive operative experience with various forms of the continent ileal reservoir in more than 1000 patients over the past 12 years has demonstrated clearly the extreme reliability and durability of this diversion system. Reflux reliably can be prevented and the upper urinary tracts protected. Patients can void or catheterize with confidence. Orthotopic diversions should now be available to most patients, both male and female. Patients should be able to live a more normal life style with a positive self image. We believe that because our modifications of the ileal reservoir systems have decreased the need for reoperation, these forms of continent urinary diversion have emerged as optimal operations and even as the standard of care in cystectomy patients. Ileal conduits should be reserved for poor-risk candidates with short-term life expectancy or for those patients not motivated for continent diversion. The most vocal advocates of the procedures remain those continent diversion patients who have had urinary diversion by another method. Patients still must be aware that complications can occur. Appropriate patient motivation and a thorough understanding of the continent diversion technique and its potential problems continue to be essential prerequisites of the operation. Although minor refinements to these systems will continue to be made, we feel that continent diversion, most often in the form of orthotopic reconstruction, can be offered safely and wisely most to patients.
