A pretty large renal pelvic calculus

This patient has a pretty large left renal calculus lodged in the renal pelvis. But surprisingly, there are no obstructive changes.

ultrasound findings: a large calculus of 2 cms in the left kidney in the renal pelvis, with no hydronephrosis:

1. A focal, hyperechoic (bright) mass is seen in the left renal pelvis.

2. The calculus is associated with acoustic shadowing.

3. The renal pelvic calculus is approximately 2 cm in size.

4. The rest of the left kidney appears normal.

5.There is no hydronephrosis (dilation of the renal pelvis and calyces).

6. Color Doppler ultrasound shows twinkle artefact posteriorly. 

The prognosis for a large calculus in the left kidney is generally good. In some cases, the calculus will pass on its own within a few weeks or months. This is difficult here due to the large size. If the calculus does not pass, it can be removed surgically or with lithotripsy (a procedure that uses shock waves to break up the calculus).

The management of a large calculus in the left kidney will depend on the size of the calculus, the patient's symptoms, and the patient's overall health. In some cases, the patient may need to be monitored closely with ultrasound to ensure that the calculus does not cause any complications. In other cases, the patient may need to have the calculus removed surgically or with lithotripsy.

Some additional information about large calculi in the left kidney:

* Large calculi are more likely to cause pain than small calculi.

* Large calculi are also more likely to cause complications, such as hydronephrosis, infection, and bleeding.

* If a large calculus does not pass on its own, it is important to seek medical attention to prevent complications.
