Read important information about studies and the participation in them.

Dear Patient,

As one of the leading European centers’ supply in robotic surgery and uro-oncology, the continuous recording of the data and the implementation of clinical trials are an important aspect of our activity. The study center of the Department of Urology and the PZNW is responsible for the planning, the coordination and the implementation of national and international studies. It focuses on the oncological diseases of the genitourinary tract, including the cancer diseases of the prostate, the kidney and the bladder. Here we have compiled for you essential information on studies and participation opportunities.

Many studies mostly include the accurate recording of data and treatment outcomes, while other studies compare different therapeutic procedures. A self-evident principle in the studies is that the participated patients do not suffer from any disadvantage during the treatment. If you are asked during your treatment to participate in a study, we would ask you to consider this favorably.

For more information on clinical trials and the currently ongoing studies, please turn to the team and their two leaders, Petra Lange and Clio Gruel, who would be happy to answer you.

Frequently Asked Questions:

  • Are patients ‘guinea pigs’ during the study?

No! We do not perform any experiment with our patients, but you will receive the best therapy which is based on the present science. They examine during the study if there exists a better treatment. Without such studies, we could not find out if there is a better treatment option. Developments in the treatment of diseases would not be possible. Making clinical studies means to work to improve the medical treatment options.

  • Who decides if you are going to be treated in a study?

Of course there is only one who decides: YOU yourself.

  • Who benefits from the trial?

Naturally you, as part of the study protocols, the monitoring of the treatment outcome is more accurate than in usual care. Future patients will also benefit from the trial what we have performed in the past. Without studies for example would not be known today that in many cases nerve-sparing prostate cancer can be operated. Due to clinical trials, at the majority of men the nerve bundles during prostate cancer surgery can be obtained wholly or partially.

  • What happens during a clinical trial?

There are different types of clinical trials. Some collects data about illnesses and the quality of life, or tissue samples are examined within the framework of the study. Other studies compare treatment methods. Here, for example therapeutic methods are compared, among which is not known whether the one or the other method offers advantages. During them a random classification is made (also called randomization) into different treatment arms. When the trial is over, by medical statistical analysis is determined, which therapy shows better results. Often many patients’ data must be analyzed to eliminate individual influential factors. It will only work if the data of the disease, treatment and results are well documented. This is exactly what a ‘study’ makes.
