To answer your question, disputing will not extend the time a derogatory is on credit report, however, you should never ever dispute accurately reporting derogatory items on your credit report. Disputes are for removing inaccurate information from your credit report. By disputing accurate derogatory information, it will be updated and drop your FICO score.

I will have to disagree with the statement of item dispute and update causing a fico drop, I have had 2 updated items in the last month , independently cause a slight bump in one CB or the other. I have also seen inquiries on major CCs cause up to a 10 point bump in one CB or the other. Not sure if these events are situational or file specific to me , but they defy everything I have learned and normal activity for others .
Unfortunately, disputing a derog caused my score to drop quite a few points. It was a medical collection for $1,600, and I was trying to get an early exclusion with Experian. They said the DoFD was Jan 2012 and it would come off Jan 2019. So when I disputed it, it came back verified, and the collection started updating monthly. Before that, it was just some long ago forgotten debt that probably wasn't impacting my score all that much. I just had to be impatient... Funny thing is it actually fell off my report on Monday. So much for Jan 2019! Apparently EX does exclude these things 3 months early.
