Master S.K., was referred to us with pain on right side of tummy and hematuria (blood in urine) on and off for last one month.
|
|
|
|
Ultrasound scan showed a 1cm sized stone in the pelvis of right kidney. There was minimal hydronephrosis seen.
|
| The child was planned for Extra-corporeal Shock Wave Lithotripsy (ESWL). |
| Under anesthesia, as a first step cystoscopy was done and a DJ stent (a small plastic pipe) was placed into kidney. This DJ stent allows the small stone fragments to be passed without much pain/ blockage. |
| The child was placed on the ESWL table under sedation (sleep). The x-ray machine and ESWL machine was focused on the stone and lithotripsy started. The stone was seen to fragment completely within 30 minutes. |
| Child was sent home in the evening of procedure. A check Ultrasound and x-ray 2 weeks later showed complete clearance of stone fragments and the DJ stent was removed. |

About Extra-corporeal Shock Wave Lithotripsy (ESWL) in Children
|
|
ESWL involves using the shock waves to break the stone into pieces. These shock waves are generated in a machine and transmitted via a globe which is kept in contact with the kid’s body. ESWL is a completely non-invasive procedure and is practically pain free.
|
|
Advantages of ESWL
Non-invasive- no cuts/ scars
Painless
|
|
Disadvantages
Can be used for stones only in selected locations
Cant be used for stones bigger than 1.2 cm or multiple stones
If the stone does not break, a endoscopic surgery may still be required.
