How to insert a urinary catheter during surgery in men

After surgery, people will not be able to go to the toilet because the patient is very weak. However, urination and defecation are necessary processes for the human body. Therefore, in this case, a catheter needs to be inserted for urination. Men need to insert a catheter into the urethra after surgery, but the male organs are not conducive to the insertion of a catheter. Let's take a look at how to insert a catheter after surgery for men?

1. Catheterization Catheterization is a method of inserting a sterile catheter into the bladder through the urethra to drain urine. Catheterization can cause nosocomial infection. Therefore, during the operation, the aseptic technique should be strictly mastered and the anatomical characteristics of the male and female urethra should be familiar to avoid increasing the pain of the patient.

(I) Purpose 1. To relieve urine retention caused by various reasons. 2. To detect urethra and find no stenosis or obstruction. 3. To check bladder function, measure bladder capacity, pressure and residual urine volume. 4. To inject contrast agent or perform drug infusion therapy.

(II) Supplies 1. The disinfection bag contains 1 small curved plate, 2 forceps, 10 large cotton balls, 2 gauze, and 1 left-hand glove. 2. The catheterization bag contains 1 square plate, 2 treatment bowls, 1 catheter No. 8 and No. 10, 2 hemostatic forceps, 2 small medicine cups, 2 large cotton balls, 1 drape, 2 gauze, and 1 pair of gloves. 3. Also prepare 0.1% Sanitary solution, sterile paraffin, adhesive tape, treatment towels, large towels, and curved plates.

(III) Operation method 1. Female catheterization

The female urethra is short, about 3-5cm long, and is highly dilating. The urethral opening is below the clitoris and is sagittally fissured. In elderly women, the perineal muscles are relaxed and the urethral opening is retracted, so it should be correctly identified when inserting a catheter.

(1) Prepare supplies and go into the ward. Explain the purpose to the patient, obtain cooperation, and shield the patient.

(2) For those who can take care of themselves, instruct them to clean their vulva. For those who cannot get up, assist them to clean their vulva. The patient lies on his back, and the nurse stands on the right side of the patient. The nurse folds the blanket in a fan shape and covers the patient's chest and abdomen. The nurse removes the proximal leg and covers the opposite leg. The proximal lower limb is covered with a large towel. The nurse instructs the patient to bend his knees and spread his legs naturally to expose the vulva.

(3) Place the treatment towel (or disposable diaper) under the buttocks and place the bent tray at the end of the bed. Open the disinfection bag, prepare the disinfectant, wear sterile gloves on your left hand, place the prepared cleaning and disinfection items between the patient's legs, hold the hemostatic forceps in your right hand and use a cotton ball with 0.1% Sanger solution to clean the vulva. The principle is from top to bottom and from inside to outside (1 for the external mound and 1 for each inner thigh). After cleaning, change the hemostatic forceps, use the thumb and index finger of your left hand to separate the labia majora, and use the urethra as the center. The order is: urethra, vestibule, and both sides of the labia majora and labia majora are cleaned with a cotton ball each. The last cotton ball is used to disinfect the urethra to the perineum and anus. Each cotton ball is used only once. The dirty cotton ball and used forceps are placed in the bent tray at the end of the bed.

(4) Open the catheterization bag and prepare 0.1% new gentamicin solution and sterile paraffin. Wear sterile gloves, spread a towel, lubricate the front end of the catheter, separate the labia majora with the thumb and index finger of the left hand, and use the hemostatic forceps and sterile cotton balls in the right hand to disinfect the urethral opening again.

(5) Use another hemostatic forceps to hold the catheter and gently insert it 4-6 cm into the urethra. After urine is seen, insert it another 1-2 cm.
