Constructing artificial urinary conduits: current capabilities and future potential.

INTRODUCTION: Intestinal segments are currently used in reconstructive urology to create urinary diversion after cystectomy. Ileal conduit (IC) is dominant type of urinary diversion. Nevertheless, IC isn't an ideal solution as the procedure still requires entero-enterostomy to restore the bowel continuity. This step is source of relevant complications that might prolong recovery time. Fabrication of artificial urinary conduit is tempting idea to introduce alternative form of urinary diversion which might improve cystectomy outcomes. Area covered: The aim of this review is to discuss available research data about artificial urinary conduit and identify major challenges for future studies. Expert opinion: Fabrication of artificial urinary conduit is in range of current tissue engineering technology but there are still many challenges to overcome. There is an urgent need for studies to be conducted on large animal models with long follow up to expose limitation of experimental strategies and to gather data for translational research.
