Safely Treat Kidney Stones In Obese Patients With Lumenis MOSES Technology

Certain treatments for large kidney stones can be gruelling and invasive, with methods including surgery through an incision in the back (Percutaneous Nephrolithotomy) or removing the stones via a scope through the urethra. These less than ideal measures can make it difficult to treat individuals who are not the average idea of a ‘healthy’ person.

An obese patient, for example, can be extremely complex and sometimes impossible to treat for kidney stones with these more conventional options. Obese patients typically have more than one comorbidity, such as heart disease, hypertension, diabetes and breathing difficulties. This can pose additional risks during treatment, with prolonged use of anaesthesia and difficulties gaining access to the stones through thick, fatty walls.

In addition to this, studies have shown that factors of obesity, such as a high body mass index and weight gain can actually increase one’s risk of getting kidney stones. Therefore, it’s essential there are options better suited to this type of patient profile.

Lumenis’ MOSES™ Technology minimizes procedural time with a good safety profile, providing a safe and suitable alternative for almost all patients grappling with a variety of kidney stones of different locations, sizes, and densities. 1-4

Using high-power Holmium laser, the MOSES Technology works to fragment the stones in the urinary tract quickly and efficiently. With capabilities of up to 120 Watts and a maximum repetition rate of 120 Hz, the laser offers superior stone ablation by up to 85%, reducing treatment time by 20% and fragmentation time by 33%, therefore, diminishing the risk of prolonged use of anesthesia. 1

MOSES’ unique pulse modulation offers a 50% reduction in retropulsion, minimizing ureteral stone migration into the kidney and reducing the need for additional time devoted to stone retrieval, avoiding unnecessary stress on the body. 1 Using the Lumenis Pulse 120H laser system with ureteroscopy poses an optimal option for obese patients as it removes the need for invasive incisions, meaning fewer obese patients will be denied treatment due to lack of access.

Offer your patients a safe and effective solution to kidney stones with Lumenis’ MOSES technology. Expand your client possibilities and provide a treatment that is compatible with the needs of obese patients, without compromising efficiency.
