Kidney surgery linked to scrotum swelling? large study investigates

This study looked at health records of 15,000 males in Ontario, Canada, to see if those who had laparoscopic pyeloplasty (a surgery to fix a blocked kidney) were more likely to later need surgery for a hydrocele (a fluid-filled sac in the scrotum). Researchers compared these patients to similar males who did not have the kidney surgery. The goal was to understand if the kidney procedure increases the risk of developing a hydrocele.
