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 ]
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 ...
Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
Water to be filtered is then applied to the filter surface until the filter clogs and the backwash cycle needs to be repeated. [3]: 264–8 [4]: 10.53–10.58 [5]: 937–9 [6]: 8.11–8.18 [7]: 353–6 Some water treatment filters use surface wash systems that break up the heavily clogged, granular media surface layer.
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.
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms ...
