Zusammenfassung der Studie

This study is conducted at the Department of Urology and the Women's Clinic of the University Hospital of Basel. After consenting to participate, patients will be randomly assigned to either group "A=Bladder irrigations with hyaluronic acid-chondroitin sulfate (Ialuril®)" or group "B=Bladder irrigations with saline solution". In both groups, 7 bladder irrigations will be performed: in the first month weekly, in the second month every two weeks, concluding after one month. To ensure equivalent treatment for all patients, neither patients nor doctors know which group assignment is in place. At the beginning of the study, all patients will be given the opportunity to document additional symptoms and tolerability via an app or paper questionnaire. We plan to enroll 70 patients in the study over 10 months.
