Tissue-engineered urinary conduit: the forerunner of regenerative medicine in urologic surgery.

In muscle-invasive and high-risk non muscle-invasive bladder cancer (BC), the procedure of choice is radical cystectomy (RC). Subsequently, a urinary diversion is formed using a segment of the gastrointestinal tract, typically the small bowel, exposing the patient to early and late complications. 

The main role of regenerative medicine in the cystectomy population would be to spare healthy bowel tissue and functionally replace diseased tissue by the creation of tissue-engineered urinary conduits (TEUCs). The aim is to produce a tissue-engineered urinary conduit with three different approaches: 

  1. animal (pig) 

  2. human (cadaver) SIS decellularized with the technique developed by Gerosa et al. to avoid toxic effects and then re-seeded with adipose-derived smooth muscle cells and urothelial cells

  3. a tubular scaffold made of PGA/PLGA polymer with the use of a 3D-bioprinter (seeded with autologous-derived adipose-derived smooth muscle cells).

 Each product will be tested for precisely controlled mechanical features. The long-term idea is to translate these techniques to more complex urological structures such as ureteral replacements or bio-engineered neobladders.
