Are they releasing any patient follow up statistics? It'd be interesting to compare their post-op complication stats to some of the 'overpriced' facilities.
Looks like you have edited your comment since you first made it.
The success rates are high and on par with western counter parts. Also this is a private hospital , I think you haven't visited a good private hospital in a developing country. Many have US/Uk trained docs and quality of service and care on par with that of developed countries.
Edit: Makes me guess, but what if their success rate is higher than the high priced facilities...
Oh and I would absolutely go for medical tourism. Beyond not being overcharged by the procedure, I wouldn't be pushed the "latest drugs" with debatable results or in a case where the latest drug is needed, it would be avaiable at a lower cost.
