Suprapubic Tap or Aspiration

CHAPTER 114 Suprapubic Tap or Aspiration



Suprapubic aspiration is a valuable diagnostic procedure, and, occasionally, it may even be a valuable therapeutic tool. In most cases, suprapubic aspiration can be performed safely at the bedside or in the clinician’s office. (For insertion of suprapubic catheters, see Chapter 113, Suprapubic Catheter Insertion and/or Change.)


To review the anatomy, clinicians should be aware that the dome of the bladder has peritoneal attachments and that needle penetration into this area can cause injury to bowel or an intraperitoneal bladder perforation. The colon lies posterior and inferior to the bladder, so the clinician should avoid advancing the needle through both walls of the bladder. Alongside the bladder, in the pelvis, lie significant vascular structures, including the common iliac and hypogastric vessels. Aspiration in this area may lead to inadvertent and significant hemorrhage.


A properly directed needle will penetrate only the skin and subcutaneous tissue of the lower anterior abdominal wall, the rectus sheath, the peritoneum, and the anterior bladder wall.
