Percutaneous nephrolithotomy

Case contributed by Mr Andrew Murphy

Presentation

Percutaneous nephrolithotomy for removal of kidney stones

Patient Data

Age: 44
Gender: Female
X-ray

Pre operative imaging

Multiple calculi in the left kidney, centred on the renal pelvis.

No ureteric calculi.

 

X-ray

Intraoperative imaging

Intraoperative imaging illustrating the steps of a nephrolithotomy procedure.

On the lower pole puncture images, prior to scope insertion, the large pelvis stone is shown as a filling defect.

X-ray

Post operative study

Percutaneous drainage tube overlies the left side of the abdomen.

Renal calculi are not perceptible on plain radiography due to marked overlying faecal residue and bowel shadows which obscure the kidneys.

CT

Post operative study

Post left PCNL

Tiny 2 mm residual calcific fragment within a lower pole calyx.

The large pelvis stones are no longer evident. Left hydronephrosis and perinephric stranding likely secondary to treated obstruction.

Case Discussion

Percutaneous nephrolithotomy (PCNL) is a surgical procedure for the extraction of large renal calculi. It is usually performed in the operating theatre either by a urologist or combined urologist-radiologist team.

This case is to illustrate the typical imaging pathway of a percutaneous nephrolithotomy, including the images intra-operatively.
