How to Perform ESWL is a practical, fundamentals-based course designed for ESWL operators, including physicians, technicians, and clinical users involved in shock wave lithotripsy procedures.

This course provides a structured step-by-step approach to performing extracorporeal shock wave lithotripsy safely, accurately, and effectively. It focuses on the complete operator workflow, from pre-procedure preparation to patient positioning, stone targeting, acoustic coupling, energy ramping, shock wave frequency, treatment monitoring, and post-treatment technical checks.

Rather than teaching ESWL as a simple shock delivery procedure, this course presents it as a controlled clinical and technical process. Learners will understand why successful ESWL depends on correct patient preparation, accurate stone localization, proper alignment in two X-ray axes, good coupling, gradual energy ramping, appropriate frequency selection, and continuous monitoring throughout the session.

Special emphasis is placed on practical operator decisions, including how to manage stone movement during respiration, when to use abdominal compression, how to avoid common alignment mistakes, how to recognize poor coupling, when to pause or adjust treatment, and why ramping is the backbone of successful ESWL.

This course is device-neutral and focuses on core ESWL principles rather than brand-specific operation. Operators must always follow the official instructions for use, institutional protocols, and manufacturer-specific training for the lithotripter system used in their clinical practice.

By the end of this course, learners will have a clearer understanding of how to perform ESWL as a structured, precise, and patient-focused procedure, with the goal of improving treatment quality, safety, and outcomes.

Prepare the lithotripter system before treatment, including calibration, coupling interface checks, and safety verification
Review patient imaging and identify important stone characteristics such as location, size, density, and visibility
Recognize the importance of patient preparation, including analgesia, hydration, comorbidities, and treatment readiness
Position the patient for stable targeting and an unobstructed shock wave path
Understand the focal zone and why accurate three-dimensional stone alignment is essential
Perform X-ray-guided stone alignment using zero-degree and thirty-degree views
Target stones consistently during the correct respiratory phase to reduce misalignment
Apply gel or water coupling correctly and avoid air bubbles that reduce energy transmission
Reconfirm stone alignment after coupling and before shock wave delivery
Understand why SWL should never start at high energy
Perform controlled energy ramping and understand why ramping is the backbone of successful ESWL
Select shock wave frequency thoughtfully and understand why slower frequencies are often preferred
Monitor stone fragmentation and targeting during treatment using low pulsed fluoroscopy where appropriate
Manage stone movement, patient discomfort, coupling issues, and situations where treatment should be paused or adjusted
Complete the session safely with proper post-treatment checks and documentation

SWL System Basics and Shock Wave Principles
This chapter gives learners the essential technical foundation of SWL, including how shock waves are generated, how the focal zone works, and how different imaging systems support stone targeting.

Pre-Procedure Preparation
This chapter explains how to prepare the lithotripter, imaging system, and patient before treatment begins, with emphasis on safety, readiness, and treatment planning.

Patient Positioning and Focal Zone Awareness
This chapter explains the importance of stable patient positioning, a clear shock wave path, and accurate stone placement within the three-dimensional focal zone.

Respiration and X-ray Guided Stone Alignment
This chapter teaches the practical workflow of X-ray-guided stone alignment, including respiratory phase selection, zero-degree alignment, thirty-degree confirmation, and final re-confirmation.

Acoustic Coupling
This chapter explains how to achieve effective acoustic coupling using gel or water, and why coupling must be checked again before shock wave delivery begins.

Common Targeting and Alignment Errors
This chapter highlights common alignment mistakes that can reduce treatment accuracy and explains how operators can avoid them during SWL.

Energy Delivery and Ramping
Delivery and Ramping This chapter explains how energy should be delivered safely and progressively, why ramping is central to successful SWL, and how operators should adapt ramping during treatment.

Shock Wave Frequency and Shock Count
This chapter explains how shock wave frequency and total shock number influence fragmentation efficiency, patient safety, and operator decision-making.

Monitoring During Treatment
This chapter teaches operators how to monitor stone response, manage movement and pain, and decide when to pause or adjust during the ESWL session.

Completing the Treatment
This chapter explains how to end the SWL session thoughtfully, avoid unnecessary shocks, and complete immediate post-treatment technical documentation.

Operator Responsibility and Course Summary
This chapter reinforces the operator’s role in treatment quality and summarizes the key principles needed for safe, precise, and effective ESWL.

On successful completion, you will receive an official Lithotripsy Academy certificate confirming foundational
