[|Human|] hi! my husband experienced pain in his scrotum that seems to be radiating from his lower back. The next morning, he noticed a yellowish crystal-like substance that came out with his urine. A very small thing like the size of a grain of rock salt. what could it be? And why the pain?
[|AI|]  Good Day, and thank you for being with Chat Doctor ! Your husband has successfully passed out a kidney stone. Blockage of the ureter will cause flank pain and will radiate to the scrotum and inguinal area because of shared nerve distribution. I would suggest getting a kidney ultrasound to check if you have more stones in the kidney. Also ask your husband to Chat Doctor.  I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.ChatDoctor .com/doctors/
