[Post-cystectomy derivations - a rule or control of technical skills?].

Limitations in gaining better understanding of bladder tumor responsiveness do exist, and accordingly the therapeutic interventions undertaken in diverse forms of the disease are conspicuous for discrepancies (M. J. Droller, 1990). E. Bricker in 1950 is the first to practically implement ileal conduit for urine derivation, and thus initiates the new and newest continent derivations. Over the period 1992-1998, in the Chair of Urology are performed 76 cystectomies with different urine derivations, using seven methods for the purpose: [table: see text] Also discussed are the conditions a derivation should mandatorily meet. Emphasis is laid on the fact that the choice of derivation is still largely dependent on the skill and experience of urologists.
