Aims and objectives: This study aimed to determine the effect of music therapy on procedural pain intensity and anxiety and comfort levels in patients during cystoscopy.

Background: Cystoscopy is a procedure that is commonly performed as day surgery in urology clinics in order to diagnose lower urinary tract system symptoms as well as to diagnose and follow up tumors associated with the lower urinary system. During cystoscopy, which is an invasive intervention, individuals may experience pain and anxiety, and their comfort may be negatively affected.

Methods: This study was a prospective, randomized controlled trial. Study participants were randomly assigned to either a control or music group. The outcome measures were assessed using the Visual Analogue Scale, State Anxiety Scale, and General Comfort Questionnaire. This report followed the CONSORT checklist.

1. INTRODUCTION Cystoscopy is a common procedure in urology clinics and has two types: flexible and rigid. Especially recently, there has been an increase in the use of flexibles. Both of these types can be preferred as a diagnostic procedure in hematuria, atypical dysuria, bladder and upper urinary tract cancers, and suspected urethral stenosis. Rigid cystoscopy can be more painful than flexible cystoscopy.
2. BACKGROUND Cystoscopy is a procedure performed in urology clinics to evaluate the lower urinary tract for a large number of symptoms and pathologies, but it is painful and causes anxiety in individuals. It is recommended to perform local anesthesia to the patients during the procedure, to select appropriate cystoscopy equipment, and to make the necessary environmental arrangements in order to reduce the patients' pain and anxiety and increase their comfort levels.

Environmental arrangements to manage interventional pain in cystoscopy include music therapy that has recently been used widely.Music is used as one of the complementary therapies in the treatment of many diseases due to its physical, psychological, and functional effects on individuals. The use of music as therapy in hospitals began to become widespread with the beginning of the world wars, but the introduction of pharmacological methods for the treatment of pain and anxiety has reduced the popularity of music in this context. With the identification of side effects of drugs in the subsequent years, starting again to use music as complementary therapy has come to the fore.

Music therapy in nursing first started in the 1800s with Florence Nightingale. Nightingale described music as an effective method in the recovery process in order to provide and increase patient comfort and reduce their anxiety levels. Music therapy has also been accepted as part of nursing practices within the scope of Nursing Interventions Classification.

In the literature, international studies have been conducted to reduce the pain and anxiety levels of individuals and increase their comfort levels. Considering two systematic reviews related to the subject;some studies noted that music played during flexible cystoscopy did not reduce pain and anxiety, while some studies stated that music could be effective in reducing pain and anxiety during cystoscopy. Controversial results were found in these two studies, which have high evidence levels. Experimental studies with control groups showed that music reduced pain and anxiety and increased comfort levels in patients undergoing flexible cystoscopy. Given the limitations of the studies on the subject and sample power/deficiencies, it may be observed that controversial conclusions have been reached about the effectiveness of music in relieving pain and anxiety. On the other hand, only one study has been found in Turkey regarding this issue. In a study, the effects of various distraction methods applied during the cystoscopy procedure (group 1: music, group 2: stress ball, group 3: video, and group 4: control) on pain, anxiety, and satisfaction were examined. The study found that the patients in the video group had lower pain and anxiety levels than those in the other groups. Considering the national and international studies available in the literature, regarding the topic of music therapy that may be effective in reducing pain and anxiety during the cystoscopy procedure, it is necessary to conduct further studies that provide high levels of evidence and produce scientific knowledge with greater sample sizes and by using randomized-controlled trials that are fundamental in assessing the effectiveness of evidence-based practices. This study aimed to determine the effect of music therapy on procedural pain intensity and anxiety and comfort levels in patients during cystoscopy.
