It's one of 10 mobile units in the United States. The Prostatron kills excess tissue in the prostate, a gland about the size of a golf ball that sits on top of the urethra in men. For reasons not entirely clear, prostates grow as men age. For some, this is no problem. For others, the clamping on the urethra restricts the flow of urine.
Urination is often difficult, sometimes impossible and often irritating.
In rare cases, the prostate swelling blocks the urethra entirely. Until now, the most common treatments were a lifetime of drugs that help shrink the prostate or a costly, painful surgery called trans-urethral resection of the prostate. Neither option was especially pleasant. With the drugs, there are side effects some men suffer. The surgery requires up to six weeks to recover, and in some elderly patients, the risks of surgery are greater.
