Welcome to this video demonstration of the Mediplus Suprapubic Catheter Introduction Set. The Suprapubic Catheter Introduction Set is prepared, the catheter bag and inflation syringe are connected in advance to allow speedy insertion when needed.
The first step is to fill the bladder. In this case, we're using a flexible cystoscope but a urethral catheter would be perfectly adequate. The bladder is palpated to ensure that it's full enough to safely insert the catheter. As usual, this catheter will be positioned about 2 to 3 centimeters above the superior border of the pubic symphysis in the midline.
The small needle is used to infiltrate the skin over the insertion site with local anesthetic. A small incision about 1 centimeter in length is made in the skin to allow easier insertion of the dilator later on. The long needle is then used to anaesthetize the track down to the bladder.
Once fluid can be aspirated from the bladder, the needle is in position. The syringe is removed and the needle is left in place. The guidewire is inserted, floppy end first, through the needle into the bladder, up to the first black mark.
Holding the guidewire steady, the needle is now removed, leaving the guidewire in position in the bladder. The trocar and sheath can then be inserted over the guidewire through the incision, previously made in the skin, down the anaesthetized track until it reaches the second black mark when it will be safely in position in the bladder. The guidewire and trocar can be removed from the outer sheath, and the catheter inserted to approximately the midpoint of its length.
The retention balloon of the catheter is then inflated with 5 ml of sterile water for injection. The syringe is detached and the sheath removed from the suprapubic tract and pulled apart.
In this instance, the position of the catheter was checked with a flexible cystoscope, but this isn't necessary. It's clear that fluid is draining freely from the bladder. A little bleeding is quite common initially.
The patient should be encouraged to maintain a high fluid intake after the procedure. A dressing can now be applied to the site as normal.
