According to WebMD and the NHS, one of the primary symptoms of kidney stones in men is sudden, severe pain that comes in waves, especially around the back, side, abdomen, groin or genitals, including the testicles and scrotum. Symptoms may also include nausea, painful urination or blood in the urine.
MayoClinic also lists symptoms such as frequent urination; red, brown, cloudy or foul-smelling urine; or vomiting that results from nausea. It is important to note that symptoms for kidney stones may not show until a stone actually moves around in the kidney or passes through to the ureter, which is the tube that connects the kidney to the bladder. As a result, it is possible for a person to have kidney stones without experiencing any noticeable symptoms.
Kidney stones have also been known to cause infections if a stone blocks the ureter completely, according to the NHS, which can lead to fever and chills. Other symptoms caused by the blockage are feeling tired or weak. Immediate medical attention should be sought if someone experiences symptoms including blood in the urine; difficulty passing urine; pain in the areas around the abdomen and genitals accompanied by fever and chills or nausea and vomiting; or severe pain that makes it impossible to find a comfortable position, according to MayoClinic.
