Following the procedure, the prostatic tissue will be swollen and irritated. Urologists often place a Foley catheter to prevent the patient from having urinary retention.

Then a guidewire is inserted through the port needle. The guidewire should not extend past the SA node of the right atrium as it can stimulate the heart arrhythmia. The port needle is then removed and the guidewire is fixed in place. The puncture is then widened by using 11-number knife and mosquito haemostat. [5]
It is performed by treating the area with an antiseptic, such as iodine-based solution, and then making a small incision to puncture the skin using a sterile instrument such as a sharp needle or a pointed scalpel. This allows the pus to escape by draining out through the incision.

A meta-analysis supports the conclusion that endoscopic carpal tunnel release is favored over the open carpal tunnel release in terms of a reduction in scar ...
A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.
The needle is then exchanged for an "introducer sheath" which is a small tube that is advanced over the introducer guide wire and into the blood vessel. The introducer guide wire is removed, and exchanged for a catheter or other medical device to be used to deliver medication or implantation of a medical implant such as a filter or a stent into ...

Breast: Breast biopsy is often performed to assess or diagnose breast cancer, and can be performed by various methods such as fine needle aspirate (FNA), core needle biopsy (CNB), or surgical removal.
