Laser resection
of bladder tumors

What is bladder cancer?

Bladder cancer is one of the most common urological malignancies. It arises from the cells lining the inside of the bladder wall and can present at different stages. The majority of cases are initially non-muscle-invasive, meaning the tumor is confined to the superficial layers of the bladder and has not yet penetrated the muscle.

In these early stages, endoscopic surgery — performed entirely through the natural urinary passage without any external incision — is the standard treatment. Precise and complete removal of the tumor is essential both for accurate staging and for reducing the risk of recurrence.

En-bloc laser resection

En-bloc Resection of Bladder Tumors (ERBT) is a modern, minimally invasive endoscopic technique. Using a thulium or holmium laser, the entire tumor is removed in a single piece — together with the underlying muscle layer — through the natural urinary passage, without external cuts.

Unlike conventional transurethral resection (TURBT), which fragments the tumor during removal, en-bloc resection preserves the specimen intact. This provides the pathologist with an undisturbed tissue sample including the muscle layer, enabling accurate staging and more reliable treatment decisions.

The laser energy achieves precise tissue cutting with simultaneous sealing of blood vessels, dramatically reducing intraoperative bleeding. The technique is suitable for a wide range of tumor sizes and locations within the bladder.

Why choose laser resection?

01.
Less bleeding

The laser seals blood vessels as it cuts, providing excellent hemostasis throughout the procedure. This leads to a clearer operative field, reduced risk of clot formation, shorter catheter time, and a faster, more comfortable recovery.

02.
Less pain

The procedure is performed entirely endoscopically without external incisions. Patients typically experience significantly less postoperative discomfort compared to conventional resection, with a shorter hospital stay and faster return to daily activities.

03.
Greater precision

The focused laser beam allows highly controlled, tissue-sparing dissection along natural tissue planes. This precision protects the surrounding healthy bladder wall and reduces the risk of perforation, even for tumors in technically challenging locations.

04.
Greater effectiveness

By removing the tumor in one intact piece with the muscle base, en-bloc resection ensures complete excision and provides a high-quality specimen for pathological analysis. This leads to more accurate staging, better-informed treatment planning, and a lower rate of residual tumor at re-resection.
