Patient's question:
The child underwent hernia surgery and was unable to urinate due to abdominal pain. A catheter was inserted, but it was not very effective and the child still felt very uncomfortable. So, why is the catheter not urinating?Doctor's answer:
Long-term catheterization can lead to a decline in bladder contraction ability, resulting in difficulty urinating. Therefore, during catheterization, the catheter valve should be opened at regular intervals and not kept fully open all the time. Additionally, after removing the catheter, patients can be guided to urinate, such as by having them listen to the sound of running water to induce urination. This may also be due to detrusor muscle relaxation combined with poor bladder contraction and relaxation function, leading to the need for catheterization.
