What should you know about left sided nephrolithiasis?

The stone may stay in the kidney or move into the ureter, where it can interrupt urine flow and cause waves of pain. The location and size of the stone, your symptoms, and whether there is infection determine the next step.

Pain from a left-sided stone is often felt in the left flank or back and may spread towards the lower abdomen or groin. Nausea, vomiting, blood in the urine, urinary urgency, or painful urination can also occur. A stone can cause no symptoms when it is not obstructing urine.

Dehydration can make urine more concentrated and may contribute to stone formation. The type of stone and your medical history matter when planning prevention. A clinician may check a urine sample, kidney function, and imaging to see where the stone is and whether urine is blocked.

Arrange a GP consultation if you have new one-sided flank pain, urinary symptoms, or blood in the urine. Assessment can guide pain relief, hydration advice, follow-up, and referral when needed. An abdominal ultrasound may be used to look for a stone or swelling of the urinary system; another scan may be considered if the picture remains unclear.

Take fluids regularly unless a clinician has told you to restrict them, and follow the recommended pain-relief instructions. Do not delay assessment if you cannot keep fluids down or your pain remains difficult to control.

Seek urgent medical care for severe or worsening flank or abdominal pain, fever or chills, repeated vomiting, confusion, faintness, or difficulty passing urine. These symptoms can occur when a stone blocks urine flow or when infection is present, and they need prompt assessment.

Seek advice promptly if you are pregnant, have one functioning kidney, known kidney disease, or a weakened immune system. Bring a list of medicines and describe when the pain started, where it travels, and any change in urination.

Ask where the stone is located, whether urine flow is blocked, what symptoms should trigger urgent review, and how follow-up will confirm that it has passed. You can also ask whether the stone should be tested and what changes could reduce the chance of another stone.
