What is aquablation (AquaBeam) of the prostate?

The AquaBeam system allows an innovative treatment of benign prostate enlargement. It removes the excess prostate tissue with a computer-controlled water jet. This procedure is also done endoscopically by way of the urethra under general anaesthetic. No electric current or heat is used to ablate the tissue and the surrounding tissue is, thus, spared as much as possible. The surgical robot, which ablates the area previously determined by the surgeon with the help of an ultrasound scan, guarantees maximum precision. This precision and the relatively moderate ablation of the tissue and the absence of heat are the reasons why ejaculation can be preserved in many cases.

Who is the procedure suitable for?

In principle, aquablation of the prostate is suitable for patients with medium to large-sized prostate glands. Patients actively taking anticoagulants are not suitable for this technique. This procedure has met with broad acceptance, particularly due to the fact that, in most cases, ejaculation can be spared.

What are the advantages of this procedure?

The procedure has been scientifically examined in various studies and, among others, compared to the results of a TURP procedure. Given a comparable improvement of urination with aquablation, there was in particular a very high number of patients in whom both ejaculation and sexual function could be preserved. Because no heat is applied during tissue ablation, patients suffering from an irritable bladder after the operation are rare.

What are the known risks and disadvantages?

Aquablation is a recently developed surgical procedure. That’s why currently there is not yet any long-term data covering more than 3 years to compare with TURP. At the moment, the data show an improvement in symptoms comparable to the TURP standard procedure. The number of patients requiring another operation was about 4% after 3 years. Post-operative bleeding is possible after aquablation, too, however rare due to the endoscopic bleeding control and treatment (haemostasis) performed by the alta uro medical team throughout the operation. The risk of involuntary loss of urine after aquablation is also very low.
