My parents wanted to know the side effects of creatine so they called the doctor and they mentioned something about kidney stones being a result. Do a lot of creatine users end up with kidney stones? I really want to give creatine a try but this is making me unsure.

I'm pretty sure that only happens when you are underhydrated (and creatine intake requires a LOT of water intake).
But hey, I don't take it (proper nutrition is already complex enough) so await someone else's opinion too.Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.

the problem is when people think "hey, if 10g of creatine is great for you. 20 will be better! and 30 would be better than 20! i'll take 30g a day, but split up over 6 doses". what happens is that your body can process and absorb only so much creatine. after that it is turned into creatinine and filtered out of the body. this is done by your kidneys/liver and can cause damage when they're so overworked for a long time.

Effects of long-term creatine supplementation on liver and kidney functions in American college football players.
The purpose of this study was to determine the effect of long-term Cr supplementation on blood parameters reflecting liver and kidney function. Twenty-three members of an NCAA Division II American football team (ages = 19-24 years) with at least 2 years of strength training experience were divided into a Cr monohydrate group (CrM, n = 10) in which they voluntarily and spontaneously ingested creatine, and a control group (n = 13) in which they took no supplements. Individuals in the CrM group averaged regular daily consumption of 5 to 20 g (mean SD = 13.9 5.8 g) for 0.25 to 5.6 years (2.9 1.8 years). Venous blood analysis for serum albumin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, bilirubin, urea, and creatinine produced no significant differences between groups. Creatinine clearance was estimated from serum creatinine and was not significantly different between groups. Within the CrM group, correlations between all blood parameters and either daily dosage or duration of supplementation were nonsignificant. Therefore, it appears that oral supplementation with CrM has no long-term detrimental effects on kidney or liver functions in highly trained college athletes in the absence of other nutritional supplements.
Long-term creatine supplementation does not significantly affect clinical markers of health in athletes.
Creatine has been reported to be an effective ergogenic aid for athletes. However, concerns have been raised regarding the long-term safety of creatine supplementation. This study examined the effects of long-term creatine supplementation on a 69-item panel of serum, whole blood, and urinary markers of clinical health status in athletes. Over a 21-month period, 98 Division IA college football players were administered in an open label manner creatine or non-creatine containing supplements following training sessions. Subjects who ingested creatine were administered 15.75 g/day of creatine monohydrate for 5 days and an average of 5 g/day thereafter in 5-10 g/day doses. Fasting blood and 24-h urine samples were collected at 0, 1, 1.5, 4, 6, 10, 12, 17, and 21 months of training. A comprehensive quantitative clinical chemistry panel was determined on serum and whole blood samples (metabolic markers, muscle and liver enzymes, electrolytes, lipid profiles, hematological markers, and lymphocytes). In addition, urine samples were quantitatively and qualitative analyzed to assess clinical status and renal function. At the end of the study, subjects were categorized into groups that did not take creatine (n = 44) and subjects who took creatine for 0-6 months (mean 4.4 +/- 1.8 months, n = 12), 7-12 months (mean 9.3 +/- 2.0 months, n = 25), and 12-21 months (mean 19.3 +/- 2.4 months, n = 17). Baseline and the subjects' final blood and urine samples were analyzed by MANOVA and 2 x 2 repeated measures ANOVA univariate tests. MANOVA revealed no significant differences (p = 0.51) among groups in the 54-item panel of quantitative blood and urine markers assessed. Univariate analysis revealed no clinically significant interactions among groups in markers of clinical status. In addition, no apparent differences were observed among groups in the 15-item panel of qualitative urine markers. Results indicate that long-term creatine supplementation (up to 21-months) does not appear to adversely effect markers of health status in athletes undergoing intense training in comparison to athletes who do not take creatine."Whoa, peanut-butter does look a lot like Cum." - Alan Aragon

The experts don't know what causes kidney stones definitively, thats coming from leading authorities on the subject let alone what your local GP suggests.
Secondly, Creatine is just amino acids... do you use a whey powder or eat a lot of red meat/eggs?
BRB why don't you have kidney stones?
Thirdly, its recommended you drink 1-2Gallons of water a day as a bodybuilder...Adding creatine to your diet isn't gonna make your body go "OHshiat, whats this substance, brb my kidneys can't filter this properly causing mineral buildup..." If you are actually a bodybuilder and live the bodybuilding lifestyle you're most likely gonna live in perfect health well into your 80s (or even later with age expectancies going up - estimated 30% of people born today will reach 100 lolwut?)
Fourthly, kidney stones aren't a major issue these days, they hurt but they aren't life threatening and can be dealt with in minor procedures.
Fifthly, Creatine is a supplement... you don't need it to do well, your body already produces it and with a good diet you should already be getting enough in to meet your requirements, it's entirely your call as to whether you want to use it..
