Effortless urination requires pressure on the abdomen to urinate, which may be due to urinary system obstructive diseases, neurological dysfunction, bladder detrusor dysfunction and other reasons. 1. Obstructive diseases of the urinary system: such as prostatic hyperplasia, bladder and urethral stones, etc. can cause dysuria, dyspareunia, and may require pressure on the abdomen to urinate. 2. Neurological dysfunction: such as spinal cord inflammation, spinal cord tumors, etc. lead to lack of power, need to press the abdomen to urinate. 3. Urinary bladder muscle dysfunction: for example, dysfunction of the urethral muscle – sphincter, resulting in dysfunction of the urethral muscle, leading to urinary effort and the need to press the abdomen in order to urinate out. It is recommended that the person who needs to press the abdomen to urinate out of the difficulty in urination should go to the hospital in time, to clarify the cause of the disease, and carry out standardized treatment under the guidance of the doctor.
