A Study is published in China in 2003 about the long term effects of vasectomy on benign enlargement of the prostrate. (BPH) The study concludes that vasectomy reduces the incidence rate of BPH significantly.
Robotic vasectomy reversal is first performed on rats in 2004. A study was done using a new microsurgical robot that had FDA approval in 2000. It was used to perform two types of reversal procedures on rats. The robot does not have the shaking hands that humans do. The initial results were that the robotic group had less obstruction or blockage than the group where humans performed the procedure. The incidence of granulomas was also much lower in the robotic groups.
A 2005 publication of research into the “no needle” technique of using a high pressure injector to administer anesthetic shows results of less discomfort to patients and is much faster acting than needle administered anesthetic.
The Vasclip which was FDA approved in 2003, has its first independent study into the effectiveness and short term complications of the device published in2006. In 2007 the Vasclip website went dead. It was found that it was not easier to reverse this procedure than a regular vasectomy. Many men got the Vasclip thinking that it would be easier to reverse when they wanted to have children again. In many cases it did more damage to the vas deferens.
Dr. Shu has performed no scalpel vasectomy for 15 years. He invented two-finger technique in facilitating the local anesthesia and holding the vas during the surgery. In 2008, Dr. Steven Shu opened his own clinic, One Stop Medical Center in Edina and Shoreview, MN which is focused on in-office procedures including no-scalpel vasectomy. In 2009 Dr. Steven Shu also adds the “no needle” vasectomy. The clinic has been doing many more vasectomies every year after the procedure-oriented clinic gained more reputation and became the number one vasectomy clinic in Minnesota. Dr. Shu was an assistant professor in the University of Minnesota medical school from 2006 to 2012, teaching no scalpel vasectomy and other office procedures.
