Urethral catheterization is insertion of a flexible catheter through the urethra into the urinary bladder.

Indications

Bladder catheterization can be done for diagnosis and/or treatment.

The main reason to insert a bladder catheter in female children is to

  • Collect a sterile urine sample for testing in very young children who cannot void on command

Less common reasons include

Contraindications

Absolute contraindications

  • Suspected lower urinary tract disruption from recent trauma

In trauma patients, lower urinary tract disruption (suggested by perineal hematoma, bleeding from the meatus, or pelvic bone injury) should be ruled out by retrograde urethrography or vaginal examination (and sometimes cystoscopy) before doing bladder catheterization.

Relative contraindications

Complications

Equipment

Sometimes prepackaged kits are available; if not, equipment required typically includes

  • Sterile drapes and gloves

  • An absorbent underpad

  • Antiseptic solution (eg, povidone iodine, chlorhexidine) with application sticks, cotton balls, or gauze pads

  • Sterile water-soluble lubricant (with or without 2% lidocaine)

  • Sterile cup for collecting urine specimen

  • Urethral catheter size varies with age: neonate (full term) to 6 months—5 to 6 French (Fr); infant or toddler—6 to 8 Fr; prepuberal child—10 to 12 Fr; adolescent—12 to 14 Fr

  • Washcloth for removing antiseptic solution after the procedure

Additional Considerations

Relevant Anatomy

  • The pediatric female anatomy is similar to the adult's, with a difference in size.

  • The female urethral meatus is the first opening below the clitoris and is located above the vaginal opening. It can be difficult to visualize if it appears closed. Also, young girls may have labial adhesions, which can make visualization of the meatus more difficult.

  • The urethra is short and straight and thus easy to catheterize.

Positioning

  • Place the patient in a supine, frog position (hips and knees partially flexed, heels on the bed, hips comfortably abducted).

  • An assistant should hold the legs or knees.

Step-by-Step Description of Procedure

The in-and-out insertion of a catheter will be described here.

  • Allow one or both parents or caretakers to remain present to comfort the child. Having them hold the child's hand, provide a stuffed animal for the child to play with, or engage in other distraction techniques can help. Occasionally sedation is needed.

  • Place all equipment within easy reach on an uncontaminated sterile field on a bedside tray.

  • Open the prepackaged kit, taking care not to contaminate the contents.

  • Place the absorbent underpad with the plastic side down beneath the buttocks.

  • Remove diaper if present and clean the area with a wet washcloth using soap and water. Dry the area with a dry towel. Then wash your hands with soap and water.

  • Put on gloves using sterile technique.

  • Apply the sterile lubricant to the end of the catheter and place on the sterile field.

  • Saturate the application sticks, cotton balls, or gauze with antiseptic solution (eg, povidone iodine).

  • Place the sterile fenestrated drape over the pelvis so that the vulva is exposed.

  • With your nondominant hand, separate the labia to expose the meatus.

  • Cleanse the area around the meatus with each application stick, gauze pad, or cotton ball saturated in povidone iodine. Clean the area with an anterior-to-posterior motion. Discard or set aside the newly contaminated application stick, gauze pad, or cotton balls. If using povidone iodine, clean 3 times then allow the area to dry.

  • Hold the catheter in your dominant free hand. Separate the labia with your nondominant hand. If the meatus is difficult to see, gently pull the vaginal introitus mucosa downward.

  • Advance the catheter gently through the urethra just until urine is obtained. Do not poke repeatedly or force the catheter. Urine should flow freely.

  • If the catheter has entered the vagina, leave that catheter in place as a landmark and obtain another catheter.

  • Collect urine in the specimen container. If the volume is insufficient, gently massage the lower abdomen over the bladder (suprapubic area).

  • Remove the catheter by pulling out gently.

  • Remove all remaining povidone iodine with a wet washcloth.

Aftercare

  • Remove the drapes.

Warnings and Common Errors

Tips and Tricks

  • Do not proceed with continued attempts at catheter placement if significant resistance is met or if the catheter feels as if it is buckling inside and not advancing.

  • If the catheter appears to be in the correct position but urine does not return, lubricant may be obstructing the drainage of urine. With the catheter held in the current position, flush the catheter with normal saline to dislodge the lubricant and see if urine returns prior to proceeding with the remaining steps.

  • If the catheter appears to be in the correct position but urine does not return and there is the possibility of anuria due to dehydration, consider providing hydration (appropriate to the patient's clinical condition) before the procedure is attempted again.

  • Consult a urologist for any issues with catheter placement or guidance on catheter size and style in select clinical scenarios. In certain situations where a catheter cannot be placed, a suprapubic percutaneous aspiration may be indicated.

Mumps
Mumps is an acute, contagious, systemic viral disease caused by a paramyxovirus. It is spread by droplets or saliva and probably enters through the nose and mouth. After a 12- to 24-day incubation period, headache, anorexia, malaise, and low-grade fever usually develop. Then several other symptoms develop over the next few days. Of these symptoms, edema of which of the following structures is most likely to peak on the 2nd day and typically last 5 to 7 days?
