Robot-Assisted Radical Prostatectomy in a Patient with a Preexisting Three-Piece Inflatable Penile Prosthesis

We report a rare case of robot-assisted laparoscopic radical prostatectomy (RARP) in a patient with a preexisting penile prosthesis. In this case, we completed RARP without removing the reservoir by using a deflation-inflation technique, and there were no complications related to the prosthesis. The patient had a negative surgical margin. The preserved three-piece inflatable penile prosthesis continued to function properly in 1 month. Reservoir-preserving RARP is technically feasible and safe. However, it is important to be aware of device-related complications. Long-term studies on the mechanical survival rate and patient satisfaction should be also performed.

Variations of the Superficial Brachial Artery in Korean Cadavers

The superficial brachial artery (SBA), a branch of the axillary artery, is one of the most common arterial variations in this area. While it is more vulnerable to accidental arterial injection or injury, it could be useful for the nourishment of a medial arm skin free flap. To analyze the relationship between the SBA of axillary origin and segmental variation of the axillary artery, we dissected 304 arms of Korean cadavers. We found an SBA of axillary origin in 12.2% of cadaveric arms. Unilateral occurrence was detected in 16 cadavers and bilateral in 10. SBAs gave rise to radial and ulnar arteries in the cubital fossa (8.9%), continued in the forearm as the radial artery (2.3%), or ended in the upper arm (1.0%). The SBA ended as ulnar artery was not found in any of the cadavers. The bifurcation of the SBA into the radial and ulnar arteries, presence of an SBA that ends in the upper arm, and the lack of continuation as the ulnar artery are characteristics of SBAs in Korean cadavers.
