Among all the circuits in urology, the catheter should be the most well-known. In front of the urology clinic, there are rows of old people with urine bags on their bodies, which should be the stereotype of many people about urinary catheters and urology. Why put a urinary catheter in the end? How is the catheter placed? How to take care of the urinary catheter? How many types of urethra are there? Let Mr. Bird Science answer for you.
Why put a urinary catheter? Intuitively, I would feel telemarketing list that the urinary catheter must be unable to urinate, so it needs to be put. It is true that this is the situation encountered by most patients, but in addition to some special conditions, doctors will also recommend temporary catheter placement: After bladder related surgery: Bladder surgery like curettage of a bladder tumor or a biopsy of the bladder, a catheter is placed after surgery to monitor bleeding and to rest the bladder.
And usually a three-channel urinary catheter is placed, one channel will be continuously filled with saline, and the other will drain the urine and saline from the bladder. After prostate surgery: If the prostate surgery is a curettage of prostate hypertrophy, a urinary catheter will also be placed to monitor the bleeding situation. More particularly, on the day after the operation, we will tighten the urinary catheter and use urine.
