Electrohydraulic cystolithotripsy

Area of Science:

• Urology
• Biomedical Engineering

Background:

• Urinary tract stones (calculous disease) pose a significant clinical challenge.
• Conventional lithotripsy methods have limitations in efficacy and ease of use.

Purpose of the Study:

• To outline the protocol and technique of electrohydraulic cystolithotripsy using the SD-1 instrument.
• To evaluate the safety and effectiveness of this method for bladder calculi fragmentation.

Main Methods:

• Electrohydraulic cystolithotripsy procedure utilizing the SD-1 device.
• Fragmentation of various types of bladder calculi (urate, phosphate, carbonate, oxalate, uric acid).

Main Results:

• The SD-1 instrument is deemed safe and effective for bladder stone crushing.
• Urate, phosphate, and carbonate calculi were easily fragmented.
• Oxalate and uric acid stones demonstrated greater resistance to fragmentation.
• The procedure was found to be superior to conventional blind or optical lithotriptors.

Conclusions:

• Electrohydraulic cystolithotripsy with the SD-1 is a safe and effective adjunct for urologists.
• The technique is easy to learn and can be combined with other urologic procedures.
• This method offers a new approach to treating urinary calculous disease.
