Urethral blockage treatment: 1. It is recommended to go to the nearest hospital immediately to clarify the cause of urethral blockage. 2. Further urological ultrasound and urethroscopy are needed. If the urethra is blocked for a long time and a large amount of urine is retained in the bladder, it is recommended to give temporary indwelling catheterization treatment. However, if the obstruction in the urethra causes complete atresia, the catheter may not be able to be placed into the bladder; if there is difficulty in catheterization, temporary suprapubic cystocentesis is recommended for drainage.3. Further urethroscopy is needed to determine the cause of urethral obstruction if available. If it is a stone, lithotripsy and stone extraction will be performed under the microscope if necessary to make the urethra open; if it is a urethral tumor, suprapubic cystocentesis and fistula is recommended to obtain a biopsy of the urethral tumor tissue and wait for pathological examination. The actual tumor can be found on the internet. In case of benign prostatic hyperplasia, temporary indwelling catheterization will be performed. The patency of the urethra can be restored by performing surgical treatment of the prostate after completing other systemic examinations and assessing that there are no contraindications.
