[Decrease in time of transurethral laser litotripsy due to micro-drainage applications]

Area of Science:

• Urology
• Minimally Invasive Surgery
• Laser Technology

Background:

• Operative time in urinary stone removal impacts postoperative complication rates.
• Clouding of the fragmentation region prolongs procedures and increases risks.

Purpose of the Study:

• To develop a method for reducing operative time in holmium laser lithotripsy.
• To minimize postoperative complications associated with urinary stone fragmentation.

Main Methods:

• In vivo measurements of stone fragmentation time using a holmium laser lithotripter.
• Utilized semirigid and flexible ureteroscopes for fragmentation.
• Implemented author's percutaneous micro-drainage technique for severe fragmentation region clouding.
• Statistical analysis of measurement data using Excel.

Main Results:

• Increased duration of contact laser lithotripsy correlates with higher postoperative complication rates.
• The developed percutaneous micro-drainage technique reduced average additional washing time by four times.
• This method effectively shortens transurethral contact holmium lithotripsy duration.

Conclusions:

• Percutaneous micro-drainage significantly reduces operative time in holmium laser lithotripsy.
• Reducing fragmentation region washing time by at least fourfold lowers postoperative complications.
• This technique offers a promising approach to improve patient outcomes in urinary stone treatment.
