Use of Ohmmeter for Detection of Leak in Hydraulic Penile Prostheses: A Case Report.

Hydraulic urinary prostheses have generally been accepted as
important treatments for erectile dysfunction and urinary
incontinence. Complications of these devices are usually treated
with replacement if they fail after 5-years, based on the recommendations of their manufacturer.

A 67-year-old male with a history of robot-assisted laparoscopic
prostatectomy and bilateral lymph node dissection presented with progressive erectile dysfunction
post-operatively. He failed to respond to conservative therapy and underwent
implantation of an American Medical Service 700 inflatable penile prosthesis approximately 2-years ago.

The patient indicated that the device had worked well for one year but then noted that he had
to pump his inflatable prosthesis multiple times and could never
obtain an erection as rigid as that achieved initially. Eventually, the
patient noted that the pump went flat after about 5 compressions. He denied any fever or chills or pains in his abdomen.

After medical clearance we proceeded to access the penile tubing via the original penoscrotal
incision. Once the silicon tubing to both cylinders and the reservoir were located, we used
an ohmmeter to find the leak. The tubing appeared to be intact so
we accessed the connectors of the tubing of the IPP.

After testing, each of the components it was determined that the leak was in the
reservoir. It was mobilized via a transverse incision in the left lower
quadrant where the reservoir was located.

The tubing helped us track location of the reservoir by slight
traction on the reservoir itself. The tubing
from the new reservoir was then tracked
to the pump for connection using a modified knitting needle.
