Urinary Stones


Stones can form in the urinary tract. Urinary stones might be asymptomatic. On the other hand, some stones  might cause severe pain. Patients might experience nausea and vomiting at the same time. You might have some blood in your urine. Stones might block the flow of the urine. To diagnose the presence of urinary stone, your Dr. would ask for a Urine Test and an Imaging Study like ultrasound or CT scan. CT scan is more accurate.

Notice- Ureteral stone plus fever is a Urological Emergency. 

Possible Locations for Urinary Stones

Urinary stones usually form in the Kidneys. Then they might stay there or they might move and pass through your urinary system. There are 2 long and thin tubes that connect your kidneys to your bladder. These are called Ureters. Stones might get stuck in Ureters and cause severe pain. Sometimes stones form in ureter or bladder if there is a stasis or a foreign body.

Urinary stones

Stones usually form in the kidneys and pass down the ureters. Sometimes they get stuck there and cause severe pain. Most of the time they pass by themselves. However, if they don't, we  would break the stones. There are different methods for doing this. Your surgeon will choose an appropriate method for you base on stone location, size, your preferences and his or her preferences.

Urinary Stones Imaging:

Ultrasound and spiral CT scan without intravenous dye are used to see urinary tract stones. Spiral CT scan is more accurate. Ultrasound might miss some stones in the ureters. Ureters are  tubes that connect kidneys to the bladder.

Extracorporeal Shock Wave Lithotripsy

Extracorporeal shock wave lithotripsy (ESWL) uses sound  waves to break stones into small pieces  that can pass spontaneously.It is  is the most common type of lithotripsy. Other minimally invasive methods include (percutaneous nephrolithotomy and retrograde intrarenal surgery (RIRS).

Retrograde intrarenal surgery:

Retrograde intrarenal surgery or RIRS is one of treatment options for kidney stones when ESWL is not an option.
