In a nutshell

This study compared two different types of surgery to remove kidney stones. The study found that an incision through the skin increased the chances of removing large kidney stones.

Some background

Kidney stones are a common problem which can cause severe pain in patients. Retrograde intrarenal surgery (RIRS) involves the use of a tube inserted through the urethra and bladder to remove kidney stones. Percutaneous nephrolithotomy (PCNL) involves removing stones by accessing the kidneys through an incision in the skin. It is necessary to compare treatments to find out which one is more effective.

Methods & findings

The results of 11 studies were pooled into a single analysis. The studies included compared the effectiveness of RIRS and PCNL. The studies were assessed for quality and relevance.

Overall, an 11% higher rate of being free of kidney stones after surgery was seen in patients who underwent PCNL. 9 studies found that PCNL was superior to RIRS with a 7% increased chance of being free of kidney stones after surgery.

The bottom line

The study concluded that both procedures are safe and effective in treating large kidney stones. However, the likelihood of being stone-free was higher with PCNL.

The fine print

More research may be required on RIRS vs PCNL in treating smaller kidney stones.
