说起这个确实有些残酷，但还是讲讲吧。你可能会好奇，在没有现代医疗技术的时代，在没有现代医疗超声破碎技术的时代，是怎么处理男人肾结石的。说实话，过程非常痛苦。他们会用一根钉子，从尿道插进去对准结石，然后敲打它，把结石敲碎成小块。这样一来，这些小块就能随着排尿排出体外。但这绝不是一蹴而就的事情——这些尖锐的结晶碎片需要通过多次、极其痛苦的排尿过程排出。而且，直到1846年之前，这一切都是在没有任何止痛措施的情况下进行的。听起来是不是很恐怖？
Talking about what is tough, here it goes. You might wonder how men dealt with kidney stones before all the modern tech we have now. Well, it wasn't easy. They used a looooong nail, which they stuck into the urethra, and then hammered it to break up the stones into smaller pieces. These pieces could then be passed when they peed. It wasn't just a quick process—these sharp pieces of crystal had to be peed out in several painful trips to the bathroom. Oh, and all of this was done without any kind of pain relief until 1846.
