Detailed Description

Urinary retention is the inability to urinate despite a full bladder and is a common complication of surgery and anesthesia. Excessive urinary pressure and bladder distension are emergencies that can lead to kidney damage or dysfunction. Various methods are used to prevent urinary retention, including imitating the sound of running water, massaging the bladder, taking a warm bath, and perineal water flow. A literature review found no studies examining the effect of the sound of running water on pain, but found studies on other distraction methods used during painful procedures in children. Therefore, this study aimed to investigate the effects of watching a quiet video and listening to the sound of water in a virtual reality setting on urination, fear, and pain in the postoperative period.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control group
A group that will not receive any intervention and will be observed. After surgery, children are told not to hold their urine and are observed. 35 children are evaluated.
Experimental: Experimental group-1 (listening to water sound)
The group that will listen to the sound of water. After the surgery, children are made to listen to the sound of water and their urination times, fear and pain levels are evaluated. 35 children are evaluated.
Other: Listening to the sound of water
Urination status will be examined by listening to the sound of water or watching a video with water sound through VR glasses.
Other Names:
  • Watching videos with mute sound using VR glasses
Experimental: Experimental group-2 (watching videos with VR glasses)
The group will watch a video with the sound of water using virtual reality. After the surgery, children are shown a video with the sound of water using VR glasses to assess their urination, pain, and fear. 35 children are evaluated.
Other: Listening to the sound of water
Urination status will be examined by listening to the sound of water or watching a video with water sound through VR glasses.
Other Names:
  • Watching videos with mute sound using VR glasses

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Wong Baker Facial Pain Assessment Scale
Time Frame: After the research is completed, approximately 6 months

This scale will be used to assess the level of pain during urination in children

before and after surgery. A scoring system of 0-10 will be used. 0 indicates no pain, and 10 indicates the most severe possible pain.
After the research is completed, approximately 6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Child Fear Scale
Time Frame: After the research is completed, approximately 6 months
This scale will measure a child's fear of urination before and after surgery. A score of 0-4 will be given, where 0 represents no fear at all and 4 represents the highest possible level of fear.
After the research is completed, approximately 6 months
