"Poland's first kidney paired donation transplant was been performed last Tuesday by specialists at the Department of General and Transplant Surgery, University Hospital of the Infant Jesus in Warsaw.
Kidney extraction and transplantation surgeries were performed by Prof. Andrzej Chmura, Prof. Artur Kwiatkowski and Dr. Rafał Kieszek. Transplantation coordinator of the entire project was Aleksandra Tomaszek.
"The Department of General and Transplant Surgery, University Hospital of the Infant Jesus in Warsaw performs 40 percent of all transplants from living donors in Poland. 55 such procedures were performed in Poland in 2014."
And here (in Polish) is an announcement of a lecture on matching algorithms used in kidney exchange:
Teoria gier w służbie transplantologii. Wykład interdyscyplinarny prof. Marka Szopy.
Google Translate renders it like this:
Game theory in the service of transplantation. Interdisciplinary lecture prof. Brand Sheds
(Google translate is thorough: it also tries to translate Polish names...:)
"Today will be a lecture by Professor. Brand Sheds on the use of algorithms in transplantation. The lecture is held in connection with the February first Polish cross-kidney transplant operation. During the lecture, professor of physics will bring the way in which they were matched donor organs and global trends that are based on algorithms."
