What is the cause of urine impassability?

Urinary obstruction is mostly caused by urethritis, bladder stones, prostate hyperplasia and other reasons. The

patient's urethra suffers from pathogen infection, inflammation stimulates urethral mucosa congestion and edema, which can lead to urethral stricture and urinary obstruction; if the patient has stones in the bladder and stones block the urethra, it will cause symptoms such as urinary obstruction, pain, abdominal distension, etc.; if the patient has prostate hyperplasia, the hyperplasia site squeezes the bladder outlet, resulting in bladder outlet blockage, which will also cause dysuria and urinary retention.
