It is an outpatient or office-based procedure. The equipment consists of a vapor generator and a transurethral delivery device. The latter is similar to a cystoscope with an optical system with a 90° extending retractable 10.25 mm long injection needle (diameter 1.3 mm). From this needle water vapor is circumferentially delivered via 12 holes ...
It has been the standard treatment for BPH for many years, but recently alternative, minimally invasive techniques have become available. [1] This procedure is done with spinal or general anaesthetic. A triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. The outcome ...
Aquablation therapy (AquaBeam) is a surgical procedure for men with lower urinary tract symptoms resulting from benign prostatic hyperplasia (BPH). It is in the early stages of study. [ 1 ] It is not categorized as minimally invasive as general anesthesia is required. [ 2 ]
The treatment involves inserting a special microwave urinary catheter into the hyperplastic prostatic urethra. The microwave antenna within the catheter then emits microwaves to heat and destroy the surrounding prostatic tissue. [citation needed] The procedure can take from 30 minutes to one hour and is well tolerated by patients.
Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically ...
Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
Although oxidation processes involving ·OH have been in use since late 19th century (such as Fenton's reagent, which was used as an analytical reagent at that time), the utilization of such oxidative species in water treatment did not receive adequate attention until Glaze et al. [1] suggested the possible generation of ·OH "in sufficient ...
In water treatment, coagulation and flocculation involve the addition of compounds that promote the clumping of fine floc into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve ...
