Ureteroscopic Laser Modality on Total Lasing Time and Total Energy in Patients With Large, Dense Renal Calculi
May 12, 2023 updated by: Luay, Albany Medical College
This study will examine the effects of ureteroscopic lasing technique (dusting, fragmentation and a hybrid approach) on total lasing time and total energy in patients with a large renal calculi burden of single or multiple stones with the sum of its longest diameters between 10-20 mm and having mean Hounsfield units of 1000 or more.
Study Overview
Detailed Description
This study will examine the effects of ureteroscopic lasing technique (dusting, fragmentation and a hybrid approach) on total lasing time and total energy in patients with a large renal calculi burden of single or multiple stones with the sum of its longest diameters between 10-20 mm and having mean Hounsfield units of 1000 or more.
Additionally, we will observe the impact of these parameters on total operative time.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
- Adult
- Older Adult
Accepts Healthy Volunteers
Yes
Description
Inclusion Criteria:
- Adults between the ages of 18-80.
- Any gender, race or ethnicity may be included- these factors play a small, if any role on renal calculi formation and ability to withstand procedure.
- Must be suitable for a flexible ureteroscopy as determined by the MD
- Large renal calculi burden of single or multiple stones with the sum of its longest diameters between 10-20 mm
- An average stone density of at least 1000 Hounsfield units.
Exclusion Criteria:
- Those with a stone burden less than 10mm or more than 20mm.
- Those with an average stone density below 1000 Hounsfield units.
- Patients who are dependent on mandatory anticoagulation therapies and cannot stop for surgery
- Patients that cannot undergo ureteral access sheath placement
- Patients with abnormal anatomy such as horseshoe kidney
Patients with a history of:
- Ipsilateral upper urinary tract reconstructive procedures on the side of the renal calculi
- Ipsilateral ureteral strictures
- Prior radiotherapy of the abdomen or pelvis
- Neurogenic bladder
- Spinal cord injuries
- Those who are pregnant
- Currently being treated for infection or cancer
