- 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.
