What are the main causes of urethral obstruction?

Various diseases of the urinary system and lesions of other organs adjacent to the urinary tract can cause obstruction in different parts of the urinary tract.

(1) Urethral lesions: urethral stenosis, urethral stenosis, posterior urethral valve, prostatic hypertrophy or prostate cancer, urethral injury, urethral foreign body, urethral stones, etc.

(2) Bladder lesions: Neurogenic bladder - nerve damage caused by congenital meningocele, acquired trauma, drug effects, bladder stones, bladder neck tumors, ureterocele, blood clot obstruction in the bladder, bladder neck contracture, etc.

(3) Ureteral lesions: ureteral stones, tumors, trauma, accidental ligation during surgery, extensive retroperitoneal fibrosis, etc.

(4) Kidney diseases: kidney stones, renal pelvic tumors, blood clots caused by tumor bleeding, congenital stenosis of the junction of the renal pelvis and ureter, etc.

(5) Obstruction of the urinary tract caused by lesions other than the urinary system: such as compression of the ureter by retroperitoneal or pelvic tumors, and infiltration of cervical cancer into the posterior wall of the bladder, causing obstruction of one or both ureters entering the bladder.
