kidney stones: What Are the Symptoms?

What Are the Symptoms?

Usually, the first symptom of a kidney stone is extreme pain. The pain often begins suddenly when a stone moves in the urinary tract, causing irritation or blockage. Typically, a person feels a sharp, cramping pain in the back and side in the area of the kidney or in the lower abdomen. Sometimes nausea and vomiting occur with this pain. later, the pain may spread to the groin.

If the stone is too large to pass easily, die pain continues as the muscles in the wall of the tiny ureter try to squeeze the stone along into the bladder. As a stone grows or moves, blood may be found in the urine. As the stone moves down the ureter closer to the bladder, a person may feel the need to urinate more often or feel a burning sensation during urination.

If fever and chills accompany any of these symptoms, an infection may be present. In this case, a doctor should be contacted immediately.

How Are Kidney Stones Diagnosed?

Sometimes "silent" stones - those that do not cause symptoms - are found on x-rays taken during a general health exam. These stones would likely pass unnoticed.

More often, kidney stones are found on an x-ray or sonogram taken on someone who complains of blood in the urine or sudden pain. These diagnostic images give the doctor valuable information about the stone's size and location. Blood and urine tests help detect any abnormal substance that might promote stone formation.

The doctor may decide to scan the urinary system using a special x-ray test caused an IVP (intravenous pyelogram). Together, the results from these tests help determine the proper treatment.

How Are Kidney Stones Treated?

Fortunately, most stones can be treated without surgery. Most kidney stones can pass through the urinary system with plenty of water (2 to 3 quarts a day) to help move the stone along. In most cases, a person can stay home during this process, taking pain medicine as needed. The doctor usually asks the patient to save the passed stone(s) for testing.

Kidney stones in adults [2]

Who Gets Kidney Stones?

For some unknown reason, the number of persons in the United States with kidney stones has been increasing over the past 20 years. White people are more prone to kidney stones than are black people. Although stones occur more frequently in men, the number of women who get kidney stones has been increasing over the past 10 years, causing the ratio to change. Kidney stones strike most people between the ages of 20 and 40. Once a person gets more than one stone, he or she is more likely to develop others.

What Causes Kidney Stones?

Doctors do not always know what causes a stone to form. While certain foods may promote stone formation in people who are susceptible, scientists do not believe that eating any specific food causes stones to form in people who are not susceptible.

A person with a family history of kidney stones may be more likely to develop stones. Urinary tract infections, kidney disorders such as cystic kidney diseases, and metabolic disorders such as hyperparathyroidism are also linked to stone formation.

In addition, more than 70 percent of patients with a rare hereditary disease called renal tubular acidosis develop kidney stones.

Cystinuria and hyperoxaluria are two other rare inherited metabolic disorders that often cause kidney stones. In cystinuria, the kidneys produce too much of the amino acid cystine. Cystine does not dissolve in urine and can build up to form stones. With hyperoxaluria, the body produces too much of the salt, oxalate. When there is more oxalate than can be dissolved in the urine, the crystals settle out and form stones.

Absorptive hypercalciuria occurs when the body absorbs too much calcium from food and empties the extra calcium into the urine. This high level of calcium in the urine causes crystals of calcium oxalate or calcium phosphate to form in the kidneys or urinary tract.

Other causes of kidney stones are hyperuricosuria (a disorder of uric acid metabolism), gout, excess intake of vitamin D, and blockage of the urinary tract. Certain diuretics (water pills) or calcium-based antacids may increase the risk of forming kidney stones by increasing the amount of calcium in the urine.

Calcium oxalate stones may also form in people who have a chronic inflammation of the bowel or who have had an intestinal by-pass operation, or ostomy surgery. As mentioned above, strived stones can form in people who have had a urinary tract infection.

Kidney stones in adults

Overview

Kidney stones are one of the most painful disorders to afflict humans. This ancient health problem has tormented people throughout history. Scientists have even found evidence of kidney stones in an Egyptian mummy estimated to be more than 7,000 years old.

Kidney stones are one of the most common disorders of the urinary tract. More than I million cases of kidney stones were diagnosed in 1985. It is estimated that 10 percent of all people in the United States mill have a kidney stone at some point in time. Men tend to be affected more frequently than women.

Most kidney stones pass out of the body without any intervention by a physician. Cases that cause lasting symptoms or other complications may be treated by various techniques, most of which do not involve major surgery. Research advances also have led to a better understanding of the many factors that promote stone formation.

An Introduction to the Urinary Tract

The urinary tract, or system, consists of the kidneys, ureters, bladder, and urethra. The kidneys are two bean-shaped organs located below the ribs toward the middle of die back. The kidneys remove extra water and wastes from the blood, converting it to urine. They also keep a stable balance of salts and other substances in the blood. The kidneys produce hormones that help build strong bones and help form red blood cells.

Narrow tubes called ureters carry urine from the kidneys to the bladder, a triangle-shaped chamber in the lower abdomen. Like a balloon, the bladder's elastic walls stretch and expand to store urine. They flatten together when urine is emptied through the urethra to outside the body.

What Is a Kidney Stone?

A kidney stone develops from crystals that separate from urine and build up on the inner surfaces of the kidney. Normally, urine contains chemicals that prevent or inhibit the crystals from forming. These inhibitors do not seem to work for everyone, however, and some people form stones. If the crystals remain tiny enough, they will travel through the urinary tract and pass out of the body in the urine without even being noticed.

Kidney stones may contain various combinations of chemicals. The most common type of stone contains calcium in combination with either oxalate or phosphate. These chemicals are part of a person's normal diet and make up important parts of the body, such as bones and muscles.

A less common type of stone is caused by infection in the urinary tract. This type of stone is called a strived or infection stone. Much less common are the uric acid stone and the rare cystine stone.

Urolithiasis is the medical term used to describe stones occurring in the urinary tract. Other frequently used terms are urinary tract stone disease and nephrolithiasis. Doctors also use terms that describe the location of the stone in the urinary tract For example, a ureteral stone for (or ureterolithiasis) is a kidney stone found in the ureter. To keep things simple, the term "kidney stones" is used throughout this booklet.

Gallstones and kidney stones are not related. They form in different areas of the body. If a person has a gallstone, he or she is not necessarily more likely to develop kidney stones.

Walkman History 101

Discussing the beginnings of the walkman probably requires a brief look at the audio scene in the '70s. The audio industry was enjoying success in the growing home stereo market, and the implementation of the transistor for a portable AM band receiver created a pocket radio "boom" in the '60s which continued well into the '70s. "Boomboxes" or battery-powered one-piece stereo systems were growing in popularity near the turn of the decade, with sound eminating through two or more loudspeakers. Consumers appreciated the ability to listen to high fidelity sound without being confined to sitting near a home stereo system. Pocket-sized micro and mini-cassette players were also successfully sold by companies like Panasonic, Toshiba and Olympus.

So, was the development of a "personal" stereo system an obvious step in the evolution of audio? Shu Ueyama of Sony cites that this invention was purely accidental. Organizational changes were taking place at Sony in 1979 and the tape recorder division was pressed to market something soon, or risk consolidation. They came up with a small cassette player capable of stereo playback. The invention was born from a tweaked Pressman (Sony's monaural portable cassette recorder) and a pair of headphones.

Sony chairman and founder Akio Morita heard of the invention and was eager to market it. The final design of the TPS-L2, the personal stereo cassette player was completed on March 24, 1979. Sony then formulated a unique marketing campaign to sell the contraption. But first, what to call it?
The name needed to present the idea of portability, so they considered Stereo Walky. Unfortunately, Toshiba was already using the "Walky" name for their portable radio line. The new product was a descendant of the Pressman so Walkman was proposed next. Senior staff responded to this name with doubts, as it sounded like a Japanse phrase clumsily made English. The name would fly in Japan but the product would be marketed in the US as the Sound-About and in the UK as the Stowaway.

Again, senior staff thought twice about the naming conventions--globally marketing a product with regional labels would prove costly, so Walkman was ambivalently accepted as the name of this new personal stereo system.

Why the World Doesn't Need Hi-Def DVDs

When did you first become cynical about the electronics industry?

Was it when VHS went out of style, and you had to buy all your movies again on DVD? Was it the time(s) you never got the rebate you mailed away for? Or was it when your computer's 90-day warranty expired, and the thing croaked two days later?

Doesn't matter. As it turns out, you didn't even know the meaning of the word cynical. This month, Toshiba's HD-A1 high-definition DVD player hit store shelves. It's the first marketplace volley in an absurd and pointless format war among the titans of the movie, electronics and computer industries.

Just contemplating the rise of a new DVD format is enough to make you feel played. What's wrong with the original DVD format, anyway? It offers brilliant picture, thundering surround sound and bonus material. The catalog of DVD movies is immense and reasonably priced. And DVD players are so cheap, they practically fall out of magazines; 82 percent of American homes have at least one DVD player.

To electronics executives, all of this can mean only one thing: It's time to junk that format and start over.

Of course, the executives don't explain this decision by saying, "Because we've saturated the market for regular DVD players."

Instead, they talk about video and picture quality. A DVD picture offers much better color and clarity than regular TV, but not as good as high-definition TV. The new discs hold far more information, enough to display Hollywood's masterpieces in true high definition (if you have a high-definition TV, of course).

UNFORTUNATELY, this idea occurred simultaneously to both Sony and Toshiba. Each dreamed up its own format for a high-def DVD. Each then assembled an army of partners. Toshiba's format, called HD-DVD, has attracted Microsoft, Sanyo, NEC and movie studios like New Line and Universal. Sony's format, called Blu-ray, has in its camp Apple, Panasonic, Philips, Samsung, Sharp, Pioneer, Dell and movie studios like Sony, 20th Century Fox and Disney. (Some companies, like HP, LG, Warner Brothers and Paramount, intend to create products for both formats.)

The new DVD players will play standard DVD's, but that's as far as the compatibility good news goes. Movies in Toshiba's format won't play in DVD players from Sony's side, and vice versa.

At first, pundits guessed that Sony's Blu-ray format might win, because it had signed up so many more movie studios, its discs have greater capacity, and the PlayStation 3, expected to top best-seller lists this fall, will double as a Blu-ray player.

But Toshiba has two aces up its sleeve. First, its first HD-DVD player is available now, giving it a head start; Blu-ray players aren't expected until the end of June. Second, this new player, the HD-A1, costs $500 — half the price of the cheapest Blu-ray deck.

The HD-A1 is a pretty big box: 17.7 by 13.3 by 4.3 inches, more like an early VCR than a sleek modern DVD player.

The $500 isn't the only price you pay for being an insanely early adopter; this baby is slow — really slow. It takes over a minute just to turn on; menus are sometimes slow to respond; and a newly inserted DVD takes 45 seconds just to get to the F.B.I. warning. (And no, even the brave new DVD format doesn't let you skip over that tiresome warning.)

The remote is a disaster; its buttons are identically shaped and illogically placed. Not only are they not illuminated, but their labels are painted on faintly and in what must be 4-point type. (A sibling model, the HD-XA1, adds minor goodies like a backlit remote — for $300 more.)

Finally, though, the movie begins — and your shield of cynicism begins to waver. As you watch the brilliant colors, super-black blacks and ridiculously sharp detail — up to six times the resolution of a standard DVD — you realize that you've never seen anything quite this cinematic-looking in your home before.

Even high-definition TV doesn't look this good; the amount of information HD-DVD pumps to your screen dwarfs what you get from high-def satellite or cable (36 megabits a second maximum, versus 19 or less).

You need a big screen to benefit from all this picture data, however. The impact of the extra detail begins to evaporate at screen sizes below, say, 35 inches.

Even on a small screen, though, you don't have to interrupt the movie to open the DVD menu (to get access to settings and extras); on a high-def DVD, the menu appears at the bottom or side of the screen as the movie continues to play.

That feature makes it quick and easy to turn on subtitles during a mumbled scene, for example, or to tune in the director's commentary track without losing your place. I watched six beautifully made HD-DVD movies from Warner and Universal, including the gut-churning "Training Day" and a spectacular "Apollo 13." (It's a tough job, but someone's got to do it.) I quickly concluded that the new on-screen menu system makes the old DVD-menu system look confusing and crude in comparison.

The new DVD generation is supposed to offer several other sophisticated features. For example, director and actor commentaries can now include video, not just audio (the director appears in a small picture-in-picture window). Similarly, the A1's built-in Ethernet jack is supposed to let you connect to the Internet for interactive features.

No movies in the first wave include any of these goodies, however. (Shades of the Camera Angle feature that was supposed to be available on movies in the original DVD format? You decide.)

On the videophile blogs, you can find several cautionary notes regarding the HD-A1's audio and video signal outputs — details that will cause average people's eyes to glaze over, but may alarm high-end movie buffs.

For example, don't buy this player if you're hoping to future-proof your home theater. As any geek can tell you, HDTV comes in several degrees of resolution: 720p, 1080i and 1080p. Weirdly, the Toshiba can't send out 1080p, which is the holy grail. (To be sure, this standard is still rare among TV sets, but it's the wave of the future.)

You should know, too, that you're guaranteed the sensational high-resolution HD-DVD picture only if your TV set has an HDMI connector (a slim, recently developed, all-digital jack that carries both sound and picture). If you use S-video or component cables instead, you may see only 25 percent of the resolution you're supposed to get — a maddening antipiracy feature that the studios can invoke at their option. (Most studios have said that they won't "down-res" those jacks, at least at first; they can begin doing so at any time, however.)

The fine print also includes cautions that the A1 contains a fan (though it's mercifully quiet), that your TV may require tweaking to tame the more intense HD-DVD colors, and that the DVD extras are not, generally speaking, in high definition.

Over all, though, the A1 does deliver the spectacular picture and sound promised by Toshiba. Should you buy one, then?

Not unless you're an early-adopter masochist with money to burn.

Reason 1: The average person can see the difference in picture quality, but only on a big, high-def screen, preferably side by side with a standard DVD signal. The leap forward is nowhere as great as it was from, say, VHS to DVD.

Reason 2: For a brand-new technology, the A1 is a reasonably priced razor — but it's got a serious blade shortage. Only 20 will be available by the end of this month, priced at $20 to $40, and only a couple of hundred are expected by year's end. (Tens of thousands are available in the traditional DVD format.)

Reason 3 (and this is the big one): You could be placing a very big bet on the wrong horse.

In fact, this might even be a race that neither horse wins; the public may well decide that regular DVD's are just fine as they are. (Remember SACD and DVD-Audio, two rival "high-definition audio" formats that also required new players and new discs? Didn't think so. Both are well on their way to the great eBay in the sky.)

You, and everyone else, have everything to gain by waiting until prices fall, the movie catalog grows and a single standard emerges. After all, how will you feel if you buy a player and a bunch of movies — and the one you picked turns out to be the Betamax of the new millennium?

Probably more cynical than ever.

On WINNING ROULETTE

Hello, I'm Lucky Ned! That "lucky" handle is what we gamblers call a misnomer, meaning that I'm not lucky. I'm smart! Smart as the smartest rocket scientist, only my science isn't rockets, it's what the casinos naïvely call "gambling." When I walk into a casino, the owners tremble and hold emergency meetings to figure out how they can stop me before I drain their bank accounts. I'm that smart.

Thanks to my smartness, I have created "systems" for winning at games. I've mastered all kinds of games, from whupping my niece at "Go Fish" to walking away from a blackjack table with every chip in the joint. Because I am not only smart but also very nice I am going to let you in on a few of my secrets for roulette.

Roulette is French for "gentleman's wagering wheel game" and it was used in ancient times when the great Monarch of France would play the game against slaves for their lives. The ball was originally a pebble and the roulette wheel was a square until Jesus Christ finally invented the circle. In those days, the number zero did not exist, neither did any numbers higher than 16. I'm not trying to show off my smarts with this information, I'm just giving a little background that will help you better understand the subtle ins and outs of the "gentleman's wagering wheel game".

The Feeling

Many of you are already aware of my incredible skills of intuition. I sense a good situation and I pounce. I sense a bad situation and I skedaddle. But for the challenging game of roulette, you don't need intuitive abilities as powerful as mine.

Ask any of these so-called mathemeticians about the "feeling" and they will laugh at you? Why? Because they are too busy in their ivory towers to understand that there are forces beyond our small minds. I understand, and you probably do too. I do not need to tell you what the "feeling" is because you will know it when you feel it. You will feel it in your nose. Walk up to any table, get as close as you can, and see what you feel. Trust your nose. If your nose says you'll win, sit down. If your nose says you'll lose, walk away. NOTE TO ADVANCED PLAYERS: You can still play even when you feel you are going to be unlucky. Just bet the opposite of everything you would have otherwise bet.

Some casinos are kind of touchy about letting you get near their roulette wheel. I have been dragged out of a few casinos and the security always says I am not allowed to tamper with gaming equipment, but the truth is THEY'RE AFRAID OF ME and my WINNING METHODS!

So, if the casino keeps you from feeling up the game, and you can't otherwise get a sense of the action, use this 100% ACCURATE METHOD: before betting any of your hard earned money, pick a number and watch to see if it comes up. If it did, this is your lucky wheel. If it didn't, ask yourself if the ball WANTED to land in that hole. Did it feel like it did? If the ball was leaning toward your number it is still a good sign. Let's face it, you won't win every time, YOU'LL ONLY WIN ALMOST EVERY TIME. Put your money on the table and get to work! Can't think of a number? Go here for a suggestion.

A Place in the Sun

Looking to beat cold weather at home, snowbirds flock to the warmer confines of the Sun Belt

ALABAMA

The roads radiate out from Birmingham like spokes in a wheel, allowing snowbirds to arrive from Huntsville, Decatur and Gadsden to the north, fill their days in Birmingham, and head south toTuscaloosa or Montgomery - before continuing on to Mobile and the Gulf of Mexico. But before they splay their toes in the fine sands of Orange Beach and Gulf Shores, RVers should explore Birmingham's Civil Rights District, where the Alabama Jazz Hall of Fame gets toes tapping in the historic Carver Theater. The Alabama Sports Hall of Fame appeals to fans of athletic pursuits, particularly if they happen to be partial to native sons such as baseball Hall of Famer Willie Mays and/or luminary trackand-field star Jesse Owens.

As they make their way south through the state, golfers may think they've died and gone to heaven, since time and again they'll come across signs for the Robert Trent Jones Golf Trail - an extensive series of courses designed by one of the game's foremost designers. The general public can play these challenging, varied courses for less cash than they might expect; the readers of no less than Golf Digest have declared the trail the best value among the world's golfing destinations.

Whether golf is addiction or anathema to them, snowbirds can find other ways to enjoy the great outdoors once down at the Gulf. The Bon secour National Wildlife Refuge is a fine way to begin a Gulf exploration. But then again, so is wandering through the back bay by kayak. (800-ALABAMA)
