Question
What could be the reason for a child not being able to urinate after having their hernia surgery?
Answer
Long-term use of a catheter may cause a decrease in the bladder’s contraction ability, leading to difficulty urinating. During the catheter use period, it is advisable to open the catheter valve at regular intervals and not to keep it fully open all the time. Additionally, after removing the catheter, you can help the patient promote urination, such as by letting the child listen to running water sounds to guide them to urinate. Difficulty urinating may be caused by detrusor relaxation and poor contraction and relaxation function of the bladder, so urinary catheterization is necessary for urination.
