I personally haven't experienced a biopsy, and I wish I would know of a few people who have undergone biopsy of the kidneys and tell me that the biopsy they underwent was worth the trouble. And the only way it's worth the trouble is that knowing the type of glomerulonephritis made a difference in the treatment, and that the treatment at best put them on a path of improving their kidney function or at worst kept the kidneys from deteriorating.Biopsies can be very useful for getting to the root cause. There are over ten types of glomerulonephritis, and the only way to know for certain is to biopsy.
Some glomerulonephritis have good treatment options.
But as "evidence-based" medicine is fond of saying, there is no double-blind RCT study to prove this, even if you had a few people saying it helped them. Chances are I doubt there would be survivors vouching for biopsy, except if those vouching would say the biopsy helped out of their deference to the 'expertise' of their doctor, with little else to back up their claim.
Just because the review authors compiled some references of 'experts' claiming that biopsy helps, and I should take their word because they're the experts? Besides, who's really going to verify if the people interpreting the biopsy really know what they're interpreting? Can they tell an immune complex apart from a peptide from a plaque? Can they really identify the so-called lesions in the fenestrated capillaries in the glomerulus? I doubt they will go to the level of detail that's needed to be very certain of their findings. Who's auditing them anyway? No one.
It's like reading the war criminal John Bolton write a book, and then saying since you can reference a book, you can lay claim to its veracity.
I'd rather be conservative in my approach and not hurt my already ailing kidneys by having it cut up for a biopsy. There's a reason why the kidneys are enclosed and protected by skin, mesentery, and a rib cage. Otherwise, it would be be flapping around like our ear lobe.
I can stick with less invasive ways of diagnosing my kidney problems, and then slowly eliminate the kind of glomerulonephritis it has, not that it's that difficult to pinpoint if I'm really the expert that I claim to be.
