I had a prostate operation via Thulium Laser performed on me in November of 2018 by Dr. Kalchev and Dr. Kefilev. The surgery was quickly and efficiently organized through MedSpa, and I give the latter a lot of credit for their effective and friendly logistical support, including preparing all the necessary documentation for insurance purposes. I was also very happy with the two doctors, from the initial consultation prior to the surgery, to my walking into the operating room, post-operating treatment and finally to my second consultation several days after the surgery. At all times, I felt like I was in the hands of experts, who on top of that, showed a very human touch and professionalism when treating me. I also have only good things to say about the care I got at the hospital where the operation was performed and where I staid overnight, be it from the anesthesiologist to the nurses on night watch. I would recommend Dr. Kalchev and Dr. Kefilev to any man who finds himself in the same situation than I was, that is: With a large enlarged prostate, acute urinary retention due to several years of BPH and the impossibility to continue on using medicines as an option. Add to that that those two doctors use one of the latest Thulium Laser equipment, with ThuLEP being at the top of non-invasive BPH-treatment operating technology now-days. Some other important things: Both doctors gave me their phone numbers while staying in Sofia and recouping, just in case I wanted to contact them for anything. And if you a non-Bulgarian speaker, you can easily communicate with them in either English or French (as it was my case).
