Final answer:
A catheter inserted through the abdomen into the bladder for urinary diversion is known as a Suprapubic catheter.
Step-by-step explanation:
A catheter that is placed in the bladder through a surgical opening in the abdomen for urinary diversion is called a Suprapubic catheter. This type of catheter offers an alternative to the traditional urethral catheter, especially when urethral catheterization is not possible or recommended. A suprapubic catheter is inserted into the bladder above the pubic bone, hence the name 'supra' meaning above and 'pubic' referring to the pubic bone.
