Dr. Allen discusses the growing focus on intrarenal pressure in ureteroscopy
“These are key, because right now our sepsis rates following ureteroscopy are, quite frankly, unacceptable,” says Jordan L. Allen, MD.
In this video, Jordan L. Allen, MD, discusses the increased focus on measuring intrarenal pressure during ureteroscopy. Allen is an endourologist at Allegheny Health Network and an assistant professor at Drexel College of Medicine in Pennsylvania.
Video Transcript:
We have a contract with Boston Scientific, and they're pushing the new LithoVue Elite. I think there's been a big shift in focus on measuring intrarenal pressures during ureteroscopy to reduce sepsis. In my practice, we switched over from the flexible reusable scopes and moved to the single use LithoVue scopes, and our sepsis rates are very low. I always use an access sheath too, to keep the pressures low, and I use a pressure bag so I can always control how high those internal pressures go. I've found sepsis rates are almost non-existent, like .1%, .2% since making those changes. I think the key is always drawing off all the fluid that's in the kidney immediately once you get up there, and then just keeping continuous flow through that sheath to prevent the pyelovenous backflow. [As] urologists, we tend to be stubborn in our ways. So, I think it'd be good to get that information out there, to show what those intrarenal pressures are.
The current LithoVue Elite models only tell you the pressures, they don't have the regulator at this point that will actually control the pressures, but that's on the horizon for them. I know a lot of people use hand irrigation when they're doing ureteroscopy. It's pretty remarkable to see how high those pressures can get with each spurt of that. They can reach over 300 centimeters water pressure, whereas if you have a pressure bag, you can set it at 150 and max it out. These are key, because right now our sepsis rates following ureteroscopy are, quite frankly, unacceptable. We've learned through the dogma of training in urology, that that's just part of the trade. But I think, from my practice, I've found that that doesn't have to be the case.

Alkaline water unlikely to prevent kidney stones, study finds
January 11th 2024"While alkaline water products have a higher pH than regular water, they have a negligible alkali content–which suggests that they can't raise urine pH enough to affect the development of kidney and other urinary stones," says Roshan M. Patel, MD.
Microbiome alterations linked to kidney stone formation
December 21st 2023"If the diversity and robust functional potential of the healthy human microbiome is repeatedly assaulted by the average Westernized lifestyle via antibiotic exposure, diet, and other environmental factors, kidney stone prevalence will continue to increase," the authors write.
