Urethral intervention to clean the prostate is a treatment for prostatitis that can reduce inflammatory irritation, but can easily damage the urethra or cause retrograde infections. Urethral intervention to clean the prostate is commonly used in the treatment of prostatitis, which usually requires the insertion of a catheter into the position of the prostate, and then the use of saline, levofloxacin solution and other medications to clean the prostate and reduce inflammatory irritation. This method usually needs to be combined with oral medications such as levofloxacin hydrochloride tablets and diclofenac sodium extended-release tablets, together with the treatment. If you go to an irregular hospital, or the doctor’s aseptic operation is not standardized, when the urethra is intervened to insert the catheter, it may damage the mucosa of the urethra, which may easily lead to urethral bleeding, or retrograde bacterial infection. If you suffer from prostatitis, you should go to a regular hospital, under the guidance and advice of the doctor, choose the appropriate treatment, and take the medication as prescribed by the doctor, so as to avoid adverse consequences.
