Suprapubic catheterization is the medical term for the surgery performed to relieve urinary retention when placing a urethral catheter is unsuccessful or is contraindicated because of certain reasons.
During this surgery, a thin, sterile suprapubic catheter is inserted into the urinary bladder through an incision on the lower intra-abdominal wall. Once the tube has been inserted, a small bulb on its distal end is inflated to keep the catheter in place. The proximal end of the catheter is connected to a urinary bag which collects the urine.
Suprapubic catheterization is performed when transurethral catheterization is not possible or is contraindicated. The common indications for this procedure are:
Suprapubic catheterization is a painful procedure which should not be taken under proper anesthesia. It is an invasive procedure and there are high chances of damage to the bladder if the patient is agitated and moving.
A patient undergoing suprapubic catheterization is usually calmed with the help of parenteral analgesia with or without sedation.
It is advisable to localize the urinary bladder with the help of ultrasonography before undertaking the procedure. One should not attempt blind catheterization in people who have undergone previous lower abdominal surgery. Even if a patient has not undergone any lower abdominal surgery, if the distended bladder is not palpable because of obesity, blind catheterization should not be done.
Once the urinary bladder has been localized with the help of ultrasound, the patient is anesthetized. The surgeon then gives an incision on the abdominal wall overlying the bladder. The suprapubic catheter is then introduced into the bladder under all aseptic precautions.
Suprapubic catheterization is contraindicated in certain conditions. These include:
Some of the complications that may arise because of suprapubic catheterization include:
