Q1 The water filter installer from the company used to say that; overhead tank cleaning. And a question is framed for water filter; answered as over head tank cleaning And for this .......? Q2 Central AC is only for a large area; windows and split at home; what is the nexus ? Q3 Another half-baked knowledge about the surgery. Today it is invasive surgery and the entire prostate is not removed but smooth passage for urine alone is set in. Illegitimate surgery alone will land people in any surgery.
Radical prostatectomy is surgery to remove the entire prostate gland and surrounding lymph nodes to treat men with localized prostate cancer. A surgeon can perform a radical prostatectomy using different techniques, in cluding: - *Robot-assisted radical prostatectomy.* The surgeon makes five to six small incisions in your lower abdomen to remove the prostate. He or she sits at a console, using instruments attached to a computer-assisted mechanical device (robot). The robotic device allows a more precise response to movement of the surgeon's hands. - *Open radical prostatectomy.* The surgeon typically makes an incision in your lower abdomen to remove the prostate. Less often, simple prostatectomy may be recommended for men with severe urinary symptoms and very enlarged prostate glands. Enlarged prostate glands are known as benign prostatic hyperplasia, or BPH. Simple prostatectomy is usually performed as a minimally invasive procedure with robotic assistance. It's not often done as an open procedure anymore. Simple prostatectomy to treat BPH doesn't always involve removing the entire prostate, as in a radical prostatectomy. Instead, this procedure removes just the part of the prostate that's blocking the flow of urine. The surgery eases urinary symptoms and complications resulting from blocked urine flow, including: A frequent, urgent need to urinate - Difficulty starting urination - Slow (prolonged) urination - Increased urination frequency at night - Stopping and starting again while urinating - The feeling that you can't completely empty your bladder - Urinary tract infections - Inability to urinate Urologists use advanced endoscopic techniques to address these symptoms without incisions in most cases.
