Bladder catheterization

 

This act consists in introducing a probe through the canal of the urethra to the bladder. The bladder The bladder is the reservoir in which urine from the kidneys is stored before being evacuated during urination. The urethra is the exit channel from the bladder.

Why this gesture? Your bladder is not emptying properly. It is necessary to allow the urine to flow outwards to relieve you and before carrying out, if necessary, a treatment of the cause having triggered the urinary blockage Are there other possibilities? Urine can also be evacuated by suprapubic drainage which consists of puncturing the bladder directly through the skin above the pubis under local anesthesia and leaving a tube in place coming out through the stomach. Your urologist will explain to you why he has chosen this method of urine diversion.

Procedures of the gesture The probe is a thin and flexible tube which is introduced into the bladder through the urethra canal: in men the passage of the probe can be felt at the level of the sphincter (muscle of urinary continence) and the prostate . However, in the majority of cases, it is a gesture of little or no pain. Local anesthesia of the urethra is possible. There are several types of catheterization: - Indwelling catheterization: the catheter can be left in place from a few hours to several months - Evacuating catheterization: the catheter is removed as soon as the bladder is empty - Intermittent catheterization: this is repeated regularly evacuating catheterization Apart from evacuating or intermittent catheterization, the bladder catheter is held in place by an inflated balloon in the bladder and a collection bag is connected to the catheter in order to collect urine. There are several types of urine collection bags, including models for the night or for the day. Some day pockets can be concealed easily under clothing. Whatever type of bag you use, you will need to empty it regularly.

Surgical technique A bladder catheter is generally very well tolerated. Temporary bleeding in the urine may occur. The catheter can sometimes cause secondary irritation of the bladder wall, which can result in urination or bladder pain, and sometimes the emission of urine through the urethra between the catheter and the canal. ; Medications can relieve these symptoms but sometimes incompletely. It is necessary to perform regular local care at the point of entry of the probe into the urethra. The ablation of the probe is painless: it requires the balloon to be deflated beforehand. In the case of an “indwelling” catheter, the urine collection bag and the catheter itself must be changed regularly. The periodicity of these changes will be decided by your urologist. Complications of this act are possible but rare: - Impossibility of placement of the probe through the urethra requiring suprapubic drainage - False route and injury to the urethra during the introduction of the probe. This results in a difficulty in positioning the probe and/or hemorrhage occurring through the meatus. Putting the catheter back in the right position generally solves the problem, but sometimes this is not possible and suprapubic drainage must be put in place. - Obstruction of the probe by bleeding in the urine or twisting of the tube - Loss of the probe by accidental tearing out or spontaneous loss by deflation of the balloon - Narrowing of the urethra Infection of the urine or genital organs in men is a more common complication. To reduce the risk of complications, it is necessary to drink plenty of water, do regular local care and prevent the probe from being bent. Your urologist is at your disposal for any information.
