I will second the OP's opinion of BPH. In the 11 years I resided in Phuket went there:
-Motorbike accident about ended up under a car, they cleaned me up, wrapped me like a mummy and I was back partying with friends 3 hours later. Ankle bone showing and when they scrubbed that, well, glad I had some beers under my belt.
-Kidney stones. Showed up frothing white foam, thought something inside me was going to burst, first guy who saw me diagnosed it, stayed the night, was fine next day.
-Laparoscopic hernia surgery. Purple egg sticking out below my beltline, doc said I was lucky I didn't burst it diving on the volleyball court. They went through my belly button, meshed me up, back on the VB court 6 weeks later.
-Dental implant. Spaghetti bolognese at a local restaurant Rawai, meat sauce had mini bones in it, anvil split two of my teeth. One in my front grill, so had the implant procedure, could not have gone better.
Sorry to hear about your friend OP, hope he recovers.
