is rarely practical.
Feed the tip of the catheter into the urethra and up to the bifur-

the shaft of the penis with some gauze (Figure 18.4c) and retract
the foreskin if necessary.
Remove your fi rst pair of gloves, clean your hands with alcohol
cation of the catheter (Figure 18.4e,f). In males position the
penis at 45° to straighten the urethra. Encourage the patient
to take slow deep breaths in and out, especially in males as
you pass through the prostate. If you are having diffi culty,
change the angle at which you are holding the penis and gen-
tly try a twisting motion - this may help you to get past the
prostate. Remember, you may not see urine draining straight
away as there may be some lubricant temporarily blocking the
Once urine is draining, fi ll the balloon up with 10 mL of sterile
gel and put on the second pair of sterile gloves.
Remove the catheter from its plastic covering and place it in the
provided kidney dish from the catheter pack.
Take the sterile white sheet from the catheter pack and tear a
small hole in the middle fold (unless already fenestrated). Place
this across the patient with the hole over the genital area giving
access to the urethra.
Insert lubricant into the urethra (Figure 18.4d). In males hold
the penis at 90° and squeeze the tip of the penis gently to keep
the gel in. In theory you should allow 5 minutes for preparations
