Hello Dear. Your pain seems to be typical of renal calculi or kidney stones. Kindly go to the physician or emergency dept. You need to get urine tested and also get an ultrasound scan of the abdomen to see for urinary stone. Treatment is tailored according to the type of stone. Urine can be strained and stones collected for evaluation. Drinking six to eight glasses of water a day increases urine flow. People who are dehydrated or have severe nausea and vomiting may need intravenous fluids. Other treatment options include: 1. Medication Pain relief may require narcotic medications. The presence of infection requires treatment with antibiotics. Other medications include: i. allopurinol for uric acid stones ii. diuretics iii. sodium bicarbonate or sodium citrate iv. phosphorus solutions 2. Lithotripsy Extracorporeal shock wave lithotripsy uses sound waves to break up large stones so they can more easily pass down the ureters into your bladder. This procedure can be uncomfortable and may require light anesthesia. It can cause bruising on the abdomen and back and bleeding around the kidney and nearby organs. 3. Tunnel Surgery (Percutaneous Nephrolithotomy) Stones are removed through a small incision in your back and may be needed when: i. the stone causes obstruction and infection or is damaging the kidneys ii. the stone has grown too large to pass iii. pain cannot be controlled 3. Ureteroscopy When a stone is stuck in the ureter or bladder, your doctor may use an instrument called a ureteroscope to remove it. A small wire with a camera attached is inserted into the urethra and passed into the bladder. A small cage is used to snag the stone and remove it. The stone is then sent to the laboratory for analysis. Hope i have answered your question. Feel free to contact me if you have any more questions. I ll be glad to help you. All the best With warm regards Dr Sanjay Kini
