In carefully screened kidney donors, survival and the risk of end-stage renal disease appear to be similar to those in the general population.  However, women who have donated a kidney have a higher risk of gestational hypertension and preeclampsia than matched nondonors with similar indicators of baseline health.  Traditionally, the donor procedure has been through a single incision of 4–7 inches (10–18 cm), but live donation is being increasingly performed by laparoscopic surgery . This reduces pain and accelerates recovery for the donor. Operative time and complications decreased significantly after a surgeon performed 150 cases. Live donor kidney grafts have higher long-term success rates than those from deceased donors.  Since the increase in the use of laparoscopic surgery, the number of live donors has increased. Any advance which leads to a decrease in pain and scarring and swifter recovery has the potential to boost donor numbers. In January 2009, the first all-robotic kidney transplant was performed at Saint Barnabas Medical Center through a two-inch incision. In the following six months, the same team performed eight more robotic-assisted transplants. 
From 1998 to 2010, Beltre put up roughly 52 WAR. In his six seasons since then, he’s added another 38 WAR. Although he’s in his age-38 season, he was worth more than 6 WAR just last year, and projection systems like ZIPS and Steamer forecasted another 3 to 4 in 2017. (Beltre missed nearly two months to start the season with a calf injury, which is a real risk of age, but he’s been great since returning and should still reach those projections.) If Beltre sticks around another four seasons or so (through age 41), he should be able to creep his second-career WAR total into the mid-to-high 40s.
