I actually loved OBGYN. The variety is awesome, the people aren't sick. Babies are dope. I decided I really don't think I have the personality to deal with being a male in that field and I moved on.IR also is extremely fast growing and making up procedures as they go. Everything is going more minimally invasive if it can. You would be surprised as what IR is doing these days. Anything they can get their hands on. As for it being "relatively minor procedures" sure compared to open surgery but you still get to do cool stuff like break up clots in stroke care and the procedures are fast so monotony won't be as much of an issue when you're not operating for 6 hours on the same case.
@Tankstah have you looked into OBGYN? You mention you like the medicine and surgical aspect of Urology plus the variety. OBGYN has a good amount of medicine involved, lots of endocrine and pharm, OR cases, and in office procedures, plus L and D is its own beast. You can do robotic cases just like urology but yea probably not the same level of surgical variety. And different pathways depending on your interests after residency, i.e. more surgical or medicine oriented fellowships depending what you like.
Granted it takes a certain personality fit if you're a guy seeing as you deal with private female parts all day every day but the patient population is generally healthy which you say you prefer.
