Urinary Stone



Hardened mineral deposits formed in the kidney are called urinary or kidney stones (calculi). These originate as microscopic particles and over the course of time develop into stones. Medically this condition is known as nephrolithiasis or renal stone disease. The kidneys filter waste products from the blood and add them to the urine. When waste materials in the urine do not dissolve completely and the kidney is unable to evacuate them, crystals and kidney stones are likely to form. Some stones may pass out of the kidney or get lodged in the ureter (tube that carries urine from the kidney to the bladder) and cause severe pain that starts from the low back and radiates to the side or groin. A lodged stone can block the flow of urine and build a backpressure in the affected ureter and kidney. Increased pressure results in stretching and spasm causing severe pain

Sign & Symptoms of Kidney Stone (Urinary Stone)

Small and smooth kidney stones may remain in the kidney or pass without causing pain (called “silent” stones). Stones that lodge in the ureter (tube that carries urine from the kidneys to the bladder) cause spasm in the urinary system and produce pain. This pain is unrelated to the size of the stone.

Other symptoms of kidney stones may include the following:

  • Blood in the urine
  • Increased frequency of urination
  • Nausea and vomiting
  • Bladder neck incision
  • Pain and burning during urination
  • Fever, chills, loss of appetite
  • Urinary tract infectionDiagnosis of Kidney Stone






Diagnosis of Kidney Stone

Laboratory Tests

  • Complete Blood Count
  • Kidney Function Test
  • Urine Routine & Microscop



  • Whole Abdomen with Kidney, Ureter & Bladder (KUB)
  • Intravenous Pyelogram (IVP)
  • X-Ray KUB




Treatment of Kidney Stone (Urinary Stone)

Ureterorenoscopic Lithotrispy with Holmium Laser is performed under epidural and spinal Printanaesthesia to treat stones located in the middle or lower ureter. A small, fiberoptic instrument (ureteroscope) is passed into the ureter. Large stones are fragmented using 100-Watt Coherent Holmium Laser.

The laser fragments the stone into sand like particles, which are then flushed out through the natural urinary passage. The advantage of Holmium Laser is its ability to fragment stones of all compositions with precision.

Thus, it is the most effective laser for the treatment of urinary stones. Patients are generally admitted on the same day of the treatment and are discharged next day, which means only 24 hours of hospitalization is required.
