About this trial

This is an interventional treatment trial for Stone Clearance

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Subject will be older than 18 years of age
  2. Subject was diagnosed with renal calculi meeting the following criteria:

    • Largest stone measures no more than 2cm on a single diameter and is no less than 0.8cm as defined by X-ray or CT.
    • Accumulative stone burden (addition of all stone diameters) is no more than 2.5cm.
  3. Subject is a candidate for FURS procedure
  4. Subject is willing and has signed the Informed Consent Form

Exclusion Criteria:

  1. Subject has undergone a previous treatment for stones in the same kidney
  2. Subject requires another, concomitant procedure, other than FURS, to be performed during this treatment session.
  3. Female subject is pregnant
  4. Concomitant anticoagulant medication that cannot be suspended during surgery

Arm Type

Experimental

Experimental

Arm Label

Stone breaking

Stone dusting

Arm Description

Lithotripsy will be performed using the Lumenis Pulse 120H holmium laser system with low frequency parameters.

Lithotripsy will be performed using the Lumenis Pulse 120H holmium laser system with high frequency parameters.

Outcomes

Primary Outcome Measures

Stone Clearance
stone clearance will be confirmed by CT or X-Ray at 1 month follow up.
Duration of catheterization time
Duration of catheterization will be measured to evaluate treatment efficiency
Procedure time
duration of the procedure as an indicator for treatment efficiency.
Usage of alternative stone extracting devices
The need of the surgeon to use baskets, forceps or saline flushing to achieve complete stone clearance. This outcome can influence both procedure time and further complication.
hospital stay
hospital duration will be measured to evaluate treatment efficiency

Secondary Outcome Measures

Intraoperative Complications
Intraoperative Complications will be evaluated based on Modified Clavien Classification- Modified Clavien Grading: Grade 1,Grade 2,Grade 3,Grade 3a,Grade 3b,Grade 4,Grade 4a, Grade 4b, Grade 5.
Visibility during procedure
clear vision of the stone and organ compartments as reflected via endoscope and video screen.
Occurrence of retropulsion that interferes with procedure
The subjective degree of stone movement and migration as a result of the laser treatment that interfere with procedure flow.
Fiber performance
The surgeon will evaluate the degree of Fiber flexibility with scope deflection- and any damage to fiber, Fiber durability- deflection without losing energy/ efficiency and any Damage to scope.
