    • 00:05The kidney's primary job is
    • 00:08to filter the blood of
    • 00:09excess waste, minerals,
    • 00:12and fluid.
    • 00:13So anything that you've consumed
    • 00:15in excess that the body
    • 00:16doesn't need or is trying
    • 00:17to get rid of, the,
    • 00:18kidneys will filter the blood,
    • 00:19convert it into urine, and
    • 00:21then pass it on to
    • 00:21the urinary tract or the
    • 00:23bladder.
    • 00:24If the concentration or the
    • 00:26amount of minerals relative to
    • 00:28the fluid is high, then
    • 00:30a crystallization of minerals can
    • 00:32come together and form a
    • 00:33stone.
    • 00:35The classic kidney stone symptom
    • 00:37is severe pain and that
    • 00:39usually happens when a small
    • 00:41enough kidney stone gets on
    • 00:42the move and tries to
    • 00:44pass. And as it's going
    • 00:45down the ureter, which is
    • 00:46the narrow tube that connects
    • 00:48the kidney to the bladder,
    • 00:50it can block the ureter
    • 00:51almost like a cork in
    • 00:52a bottle. And as the
    • 00:54ureter becomes blocked, the urine
    • 00:56being created by the kidney
    • 00:57starts to back up into
    • 00:58the kidney,
    • 00:59balloon the kidney up, and
    • 01:01stretch the capsule or the
    • 01:02skin of the kidney, and
    • 01:03that's where all the nerves
    • 01:04are. And so with that
    • 01:06stretching,
    • 01:07you get really bad pain
    • 01:08referred to as a colic,
    • 01:09very similar to really severe
    • 01:11gas pain.
    • 01:14When a kidney is blocked
    • 01:15by a kidney stone and
    • 01:17the kidney starts to back
    • 01:18up with urine,
    • 01:19that kidney becomes congested.
    • 01:22If the kidney's blocked for
    • 01:23a long period of time
    • 01:24with poor blood flow, it
    • 01:25can deteriorate the kidney. And
    • 01:26so even if someone is
    • 01:28not having symptoms necessarily from
    • 01:30a blocked kidney, we don't
    • 01:31like to sit on that
    • 01:32for too long. We'll give
    • 01:33them a chance to try
    • 01:34to pass the stone if
    • 01:34it's practical.
    • 01:36However, at some point, we
    • 01:37need to unblock that kidney
    • 01:38because you could deteriorate the
    • 01:40kidney over time, and it'll
    • 01:41affect your kidney function.
    • 01:47Most patient stones are treated
    • 01:50via ureteroscopy.
    • 01:52This is a procedure in
    • 01:53which we would pass a
    • 01:54very small flexible camera into
    • 01:57the urinary tract, up the
    • 01:58ureter, and into the kidney,
    • 02:00see the stone, visualize it,
    • 02:02break it with a laser,
    • 02:03and then recover the stone
    • 02:05fragments.
    • 02:06The main benefit of ureteroscopy
    • 02:09is that you have incredible
    • 02:10flexibility
    • 02:11to address stones in any
    • 02:12region of the urinary tract.
    • 02:14So all the way down
    • 02:15low in the ureter close
    • 02:16to the bladder, higher up
    • 02:17in the kidney throughout multiple
    • 02:19spots in the kidney.
    • 02:21Under a single anesthesia, they
    • 02:22can have all of their
    • 02:23stones treated. They're less likely
    • 02:25to need multiple procedures to
    • 02:26get them out. It's less
    • 02:28invasive in that we're not
    • 02:30making an incision into the
    • 02:31body to get to the
    • 02:32stones.
    • 02:34It is generally an outpatient
    • 02:36procedure.
    • 02:37People are back to normal
    • 02:39activities within a couple days
    • 02:40and fully recovered usually about
    • 02:42a week afterwards.
    • 02:45One of the things I'm
    • 02:46most proud about here at
    • 02:47Yale is being on the
    • 02:48cutting edge of surgical interventions
    • 02:50for kidney stones.
    • 02:52We offer
    • 02:53the whole host of operations
    • 02:55and procedures available to treating
    • 02:57kidney stones.
    • 02:58Within the realm of ureteroscopy,
    • 03:00we've adopted aspiration
    • 03:02sheets, which are almost like
    • 03:04a Dyson vacuum cleaner that
    • 03:05we can maneuver throughout the
    • 03:06kidney, break up the stones,
    • 03:08and suck out the pieces
    • 03:10and the dust,
    • 03:11which is the best predictor
    • 03:12of preventing a stone event
    • 03:14in the future, getting every
    • 03:16single morsel of stone out.
    • 03:17It also has allowed us
    • 03:19to tackle larger stones that
    • 03:22previously had to be addressed
    • 03:23through an incision in the
    • 03:25back of percutaneous nephrolithotomy.
    • 03:27Now we can go in,
    • 03:28dust them up with a
    • 03:29high power laser, suck out
    • 03:31all the pieces, and convert
    • 03:32it to an outpatient procedure
    • 03:33with a much easier recovery
    • 03:35for the patient.
    • 03:37So we've really been able
    • 03:39to miniaturize
    • 03:40and minimize the amount of
    • 03:42morbidity and pain and recovery
    • 03:44period for patients
    • 03:46requiring kidney stone surgery.
