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 ...
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.
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 ]
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 ...
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.
A Harris flush is a type of enema aimed to evacuate painful flatus from a patient who has undergone abdominal surgery. It differs from a standard enema in that it is intended to alleviate flatus, while the purpose of standard enemas is to principally remove stool. [1] A Harris Flush kit is required.
With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30 and 50 ppb. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers.
