Summary

The electromechanical impactor (EMI) offers a safer alternative for breaking ureteral stones compared to electrohydraulic lithotripsy (EHL). However, its large probe size limits its use in certain patients.

Area of Science:

Urology
Endourology
Medical Devices

Background:

Conventional electrohydraulic lithotripsy (EHL) for ureteral calculi carries a risk of ureteral injury.
The electromechanical impactor (EMI) is an EHL probe modification designed for safer stone fragmentation.

Purpose of the Study:

To evaluate the preliminary safety and efficacy of the electromechanical impactor (EMI) for treating ureteral calculi.
To assess the success rate and complications associated with EMI use in a patient cohort.

Main Methods:

A prospective study involving 23 patients with ureteral calculi treated with the EMI.
Assessment of device employability, need for adjunctive lithotripsy, and fragmentation success.
Endoscopic and postoperative imaging to evaluate for complications.

Main Results:

The EMI could not be used in 9 of 23 patients due to access issues or device malfunction.
Successful fragmentation as the sole modality was achieved in 9 patients (39% success rate).
No complications were directly attributed to the EMI during endoscopic or postoperative evaluation.

Conclusions:

The electromechanical impactor (EMI) appears to be a safe device for intracorporeal lithotripsy of ureteral stones.
The 5F probe size of the EMI limits its applicability with smaller ureteroscopes, potentially restricting its widespread use.
