The physicians and staff were exceptional
If you're considering a medical check-up abroad, here’s my honest take. I traveled from the U.S. to Istanbul for a comprehensive medical examination at Hisar Hospital, arranged through Bookimed. The physicians and staff were exceptional. I found them professional and genuinely caring. On the other hand, the overall efficiency could be improved, particularly with appointment scheduling and the wait times between departments; better coordination would make the experience smoother. Despite the delays, the quality of care and affordability made it worthwhile, and I received valuable insight into my health at a fraction of the U.S. cost.
I recently traveled from the U.S. to Istanbul for a comprehensive medical examination at Hisar Hospital, arranged through Bookimed. The physicians and medical staff were exceptional—professional, thorough, attentive, and genuinely caring. Although there were some scheduling delays and opportunities to improve efficiency, the quality of care and affordability made the experience worthwhile. I received valuable insight into my health at a fraction of what similar care would cost in the U.S. I'm grateful to Bookimed for helping coordinate my visit and to Hisar Hospital for the excellent medical care. I would absolutely recommend both to anyone considering medical tourism!
The overall efficiency could be improved, particularly with appointment scheduling, wait times between departments, and communication throughout the process. Better coordination would make the experience smoother and less time-consuming for patients.

I can confirm that this part of my medical journey was managed with thorough competence
My primary concern before traveling for a PET-CT with Gallium 68 was the logistical side of things and whether every step would be clearly explained and executed in a new medical system. These worries proved to be entirely unfounded. The entire process was managed with clear and direct communication from the staff and the surgeon, which made a significant difference. The clinic's organization was evident. Everything was handled systematically, and each stage of the diagnostic procedure was laid out for me beforehand, so there were no surprises. The approach was very professional. but I can confirm that this part of my medical journey was managed with thorough competence.

The care I received on-site was excellent
The most important thing for future patients to know is to be prepared for new realities. I came ready for a laser enucleation operation for my medium-sized prostate, but I ended up undergoing a steam ablation procedure instead after my consultation. My surgeon was very good. He clearly explained the urination improvement timeline, which was quite reassuring as I begin my recovery. Although there has been little contact from the clinic since I left, the care I received on-site was excellent. My main advice is to go in with an open mind, as your final treatment plan might be different from what you initially expected.
