If you still can’t urinate after removing the urinary catheter after prostate surgery, it is considered to be related to the decrease of bladder function, prostate hyperplasia, urethral stenosis and other factors, you need to go to the hospital for further examination to clarify the cause of the disease, and then consult the doctor in a timely manner. 1. Reduced bladder function: generally due to decreased bladder contraction function, resulting in bladder neck obstruction, thus causing the phenomenon of still not being able to urinate after the removal of the urinary catheter after prostate surgery. Reduced bladder function can be relieved by developing the habit of regular urination and prolonging the duration of urination. 2. Prostatic hyperplasia: usually due to the indwelling urinary catheter for a long time, resulting in some damage to the prostate, thus causing the phenomenon of prostate surgery after the removal of the urinary catheter still can not urinate. Prostatic hyperplasia can be treated with surgery such as transurethral resection of the prostate. 3. Urethral stenosis: It may be due to the narrowing of the urethra, which will affect the normal urine discharge, when the urethral stenosis is more serious, the urine will not be able to be discharged normally. The above phenomenon may also be caused by other factors, if there is prostate surgery after the removal of the urinary catheter or the phenomenon of urine, you should promptly go to the regular hospital for consultation and treatment, so as to avoid delays in the condition of the disease, the adverse consequences.
