Urinary Tract Calculi VI: Surgical Management

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...

Area of Science:

Urology
Medical Technology
Laser Applications

Background:

Lasers are versatile tools in urology for treating conditions like stones, BPH, and tumors.
Despite benefits, laser use involves risks influenced by wavelength, energy, and tissue interaction.
Optimal laser application knowledge is vital for reducing adverse outcomes.

Purpose of the Study:

To review the principal risks associated with laser applications in urology.
To analyze potential complications for patients, healthcare professionals, and equipment.
To summarize injury mechanisms and preventive strategies for safe laser use.

Main Methods:

A narrative literature review was conducted.
The Medline database was searched using keywords: laser, safety, risk, adverse effects, complications, urology.
Relevant articles were identified and analyzed to summarize laser-related risks.

Main Results:

Laser use in urology presents risks including patient thermal injury, strictures, vascular issues, and skin burns.
Healthcare professionals face ocular, cutaneous, and auditory damage risks.
Equipment, particularly ureteroscopes, can also be damaged.

Conclusions:

While the overall risk of laser adverse events in urology is low, consequences can be severe.
Comprehensive risk awareness is essential for urologists.
Implementing preventive measures is a fundamental requirement for safe laser practice.
