OBESITY SURGERY AND KIDNEY STONES
ANCHOR LEAD: HAVING A COMMON TYPE OF SURGERY FOR OBESITY PUTS PEOPLE AT RISK FOR KIDNEY STONES, ELIZABETH TRACEY REPORTS
The most common type of obesty operation, known as a roux-en-Y, puts people at increased risk of developing kidney stones, a Johns Hopkins study led by Brian Matlaga has found.
MATLAGA: We had about 4600 patients that we studied, and we found that patients who had undergone roux-en-Y gastric bypass were about twice as likely to be diagnosed with a kidney stone and also a little more than twice as likely to undergo a surgical treatment to remove a kidney stone. Patients are at risk for a kidney stone or to undergo treatment for a kidney stone following roux-en-Y gastric bypass. What we wanted as our take home message was not that that we should abandon roux-en-Y bypass procedures but rather to recognize that these patients are twice as likely to get a kidney stone in the postoperative period. :30
Matlaga says people who’ve had gastric bypass can use dietary measures, such as drinking more water and avoiding many other beverages such as soda, to reduce their risk of developing kidney stones. At Johns Hopkins, I’m Elizabeth Tracey.
