Longterm Ureteral Stenting: Assessment of Stent- Associated Morbidity, Associated Costs and Impact of Biofilms

This study is performed to analyze various aspects of biofilms on ureteral stents in a longterm setting.

The study is performed to provide a better understanding of the influence of biofilms on ureteral stents on the entire spectrum of stent-associated morbidity in a longterm setting.

In addition, the trial is intended to give an overview of the incidence of complaints, the occurrence of complications and their economic aspects.

The influence of biofilms on the morbidity associated with longterm ureteral stenting is assessed.

• Informed consent
• responsible patients

Exclusion Criteria:

• ongoing therapy: OAB, LUTS, urinary incontinence, chronic prostatitis, chronic pelvic pain syndrome
