Application of real-time reverse transcriptase-polymerase chain reaction in urological oncology.

Purpose: During the last decade numerous different reverse transcriptase-polymerase chain reaction (RT-PCR) techniques have been described. However, the lack of highly sensitive, quantitative and reliable methodology has been responsible for its limited use in modern urology. Early semiquantitative RT-PCR techniques often proved not to produce consistent results and have a high failure rate due to complicated working models.
