<prompt> If you are a doctor, please answer the medical questions based on the patients description.Im a retired RN, concerned about my son who lives in Houston. Im beginning to have doubts about his Urologist and need an objective opinion. My son is a prominent Petroleum Engineer and travels extensively and thus my concern regarding what seems to be, an extended amount of time to correct re-occurring kidney stones. He under went a procedure last week where it reported he had a kidney stone blocking his kidney enough that the urine was not flowing and thus he experience swelling and extensive pain. Im thinking the procedure he had was a lithotripsy, he was put under anesthesia ...return visit today shows the stone still in his kidney. I am thinking we need a new Urologist. May I have your opinion? Thank you Phyllis Nicolls  <response>: Hello Phyllis and welcome to Chat Doctor. As a Urologist, i can understand your anxiety. Often, for impacted stones, we place a DJ stent across the stone and stop. The lithography is planned after days to two weeks, depending on stone size. The other situation is, for large, dense stones, its done in 2 stages. So you may check the discharge summary and clear your doubt. If youve any doubts, send all the reports to me, as a direct question. Chat Doctor. Manga.
