The stinging sensation after inserting a urinary catheter in men, which will be eliminated within 24 hours in most cases, is mainly due to local mucosal irritation and a slight inflammatory reaction. The main purpose of inserting a urinary catheter is to drain urine, which will not cause significant damage to the entire urethra, but it can still cause local tingling due to mucosal irritation during the operation. The corresponding tingling sensation is generally not particularly intense, and most of them will disappear within 24 hours, and the corresponding symptoms of urinary tract infection will also be more persistent. During the recovery period, we should pay attention to drink more water, try to eat a light diet, do not eat spicy and stimulating food. If the symptoms do not disappear for a long time, you need to be admitted to the hospital in a timely manner, under the guidance of the clinician to carry out standardized treatment, to avoid causing delays in the condition.
