Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Summary

A fluid management system (FMS) maintained consistent irrigation flow during laser lithotripsy, significantly reducing temperature rise compared to a pressure bag in benchtop models. This suggests FMS can mitigate thermal risk during laser procedures.

Area of Science:

  • Urology
  • Medical Devices
  • Laser Surgery

Background:

  • Laser lithotripsy generates heat, posing a thermal risk to renal tissue.
  • Effective irrigation is crucial for managing intrarenal temperatures during laser lithotripsy.

Purpose of the Study:

  • To compare temperature changes during laser activation with irrigation delivered by a pressure bag versus a fluid management system (FMS).

Main Methods:

  • Benchtop experiments used a flexible ureteroscope in a kidney model with saline irrigation.
  • Systems were pressurized to 200 mmHg; laser activation (20-60W) followed.
  • Flow rate, pressures, and calyceal temperature were continuously recorded.

Main Results:

  • FMS maintained stable flow (~45 mL/min) vs. pressure bag decline (~38 to ~25 mL/min).
  • Temperature rise at 20W was 7.9°C (pressure bag) vs. 6.4°C (FMS) (P=0.02).
  • At 60W, temperature rise was 17°C (pressure bag) vs. 12.4°C (FMS) (P=0.02).

Conclusions:

  • Consistent irrigation flow rate is critical for managing thermal risk in laser lithotripsy.
  • An automated FMS effectively mitigates temperature rise and thermal dose in benchtop models.
  • FMS offers a potential advantage in enhancing safety during laser lithotripsy procedures.
