Question

If you do a paracentesis of the bladder just above the pubic symphysis, What will the needle pass through in order?

Answer 1

The needle for a paracentesis of the bladder just above the pubic symphysis passes through the skin and subcutaneous tissue, the anterior abdominal wall muscles, the peritoneum, and the bladder wall.

Step-by-step explanation:

When performing a paracentesis of the bladder just above the pubic symphysis, the needle would pass through the following structures in order:

1. The skin and subcutaneous tissue
2. The anterior abdominal wall muscles
3. The peritoneum
4. The bladder wall

The bladder lies posterior to the pubic bone and anterior to the rectum. The needle would enter the bladder wall obliquely, reaching the bladder cavity for drainage of urine.
