Kidney Stone

  Introduction Kidney stones are a common urinary health problem that can cause severe pain, discomfort during urination, blood in the urine, and other complications. They develop when minerals and salts in the urine form hard deposits inside the kidneys. While small kidney stones may pass naturally, larger stones or those causing persistent pain, blockage, or infection may require medical treatment or surgery. Kidney stone surgery includes several procedures designed to break stones into smaller pieces or remove them from the urinary tract. Modern techniques, including laser lithotripsy, allow many patients to receive minimally invasive treatment with smaller incisions or no external incisions at all. Understanding the different treatment methods, laser procedures, recovery time, potential risks, and treatment costs can help patients make informed decisions. People seeking urological consultation at Brij Lal Hospital can discuss their symptoms and available treatment options with a qualified specialist. What Are Kidney Stones? Kidney stones are hard deposits formed when substances such as calcium, oxalate, uric acid, or other minerals become concentrated in the urine and crystallise. Stones can vary in size, from tiny crystals to larger stones that occupy a significant part of the kidney. They may remain inside the kidney or move into the ureter, the tube that carries urine from the kidney to the bladder. Small stones may pass through the urinary tract without requiring surgery. However, larger stones can obstruct urine flow and cause severe pain or damage if the obstruction persists. The main types of kidney stones include: Calcium stones: The most common type, often containing calcium oxalate. Uric acid stones: May develop when urine is persistently acidic. Struvite stones: Associated with certain urinary tract infections. Cystine stones: Uncommon stones associated with an inherited condition called cystinuria. Identifying the type of stone can help doctors recommend suitable treatment and preventive measures. Symptoms of Kidney Stones Kidney stone symptoms depend on the stone’s size, location, and whether it blocks urine flow. 1. Severe Pain in the Back or Side One of the most common symptoms is sharp pain in the back or side, usually below the ribs. The pain may come in waves and can spread towards the lower abdomen or groin. 2. Pain During Urination A stone moving towards the bladder may cause burning, discomfort, or pain while passing urine. 3. Blood in the Urine Kidney stones can irritate the urinary tract and cause blood in the urine. The urine may appear pink, red, or brown, although blood may also be detectable only through testing. 4. Frequent Urination Some patients experience a frequent or urgent need to urinate, particularly when a stone is close to the bladder. 5. Nausea and Vomiting Severe pain may trigger nausea and vomiting. These symptoms can occur during an episode of renal colic, the intense pain associated with a stone obstructing the urinary tract. 6. Fever and Chills Fever or chills alongside suspected kidney stones may indicate a urinary infection, especially if urine flow is blocked. Important: A blocked kidney combined with infection can be a medical emergency. Seek immediate medical attention if you have fever or chills with suspected kidney stones, severe uncontrolled pain, persistent vomiting, or difficulty passing urine. What Causes Kidney Stones? Kidney stones develop when urine contains more stone-forming substances than it can keep dissolved. Several factors can increase the risk. Common risk factors include: Not drinking enough fluids. High concentrations of calcium, oxalate, or uric acid in urine. A family history of kidney stones. High salt intake. Certain dietary patterns. Obesity and some metabolic conditions. Recurrent urinary tract infections. Certain medicines or inherited disorders. Previous episodes of kidney stones. Not every patient develops stones for the same reason. A medical evaluation, stone analysis, and sometimes specialised urine tests can help identify individual risk factors. How Are Kidney Stones Diagnosed? Doctors use a combination of medical history, examination, and investigations to determine the stone’s size, location, and possible complications. 1. Ultrasound Ultrasound can identify many kidney stones and signs of urinary obstruction. It is often used when avoiding radiation is important. 2. CT Scan A non-contrast CT scan is frequently used when detailed information about a suspected kidney stone is required. It can help determine the stone’s size, location, and density. 3. Urine Tests Urine tests may identify blood, signs of infection, or crystals. A urine culture may be recommended if infection is suspected. 4. Blood Tests Blood tests can help assess kidney function, signs of infection, and relevant mineral or metabolic abnormalities. 5. Stone Analysis If a stone passes naturally or is removed during treatment, laboratory analysis can identify its composition. This information may help guide future prevention. Kidney Stone Treatment Options Not every kidney stone requires surgery. The appropriate treatment depends on the stone’s size, location, symptoms, kidney function, and whether infection or obstruction is present. 1. Conservative Treatment Small stones may pass naturally through the urinary tract. A doctor may recommend adequate fluid intake, pain relief, monitoring, and follow-up imaging. Certain medicines can help selected patients pass a ureteric stone, depending on its size and location. Patients should not force excessive fluid intake during an acute obstruction or follow a self-treatment plan without medical advice. 2. Extracorporeal Shock Wave Lithotripsy (ESWL) ESWL uses focused shock waves generated outside the body to break a kidney stone into smaller fragments. The fragments can then pass through the urinary tract. Potential benefits: No surgical incision. Usually performed without inserting instruments into the urinary tract. Suitable for selected stones, depending on their size, location, and characteristics. ESWL may not work well for every stone. Some patients require repeat treatment or another procedure, and the fragments can cause discomfort while passing. 3. Ureteroscopy Ureteroscopy involves passing a thin instrument through the urethra and bladder into the ureter or kidney. The urologist locates the stone and may remove it using a small basket or break it into fragments. This approach is commonly used for ureteric stones and selected kidney stones. A temporary ureteric stent may be placed to help urine drain after … Read more
