On behalf of the European Section of Urological Research and the Society for Basic Urologic Research They are very pleased to extend an invitation to join the 11th World Congress on Urological Research in Nijmegen, The Netherlands. It is particularly important to organise a focused meeting in which researchers from both sides of the Atlantic will intensively discuss recent advances in molecular classification of urological cancers, tissue engineering, andrology, exosomes and tumor metastasis. Experts from both sides of the the Atlantic have been invited to deliver lectures on the most recent exciting results in progress in their field.
