Living Donor Research Living Donor Risks Living Kidney Donor

A Little Less Air Please

Most living kidney donors undergo a laparoscopic procedure, which involves pumping the abdominal region full of gas/air. This lifts the muscle and skin away from the organs and provides the surgeon and surgical tools with a clearer visual field (think about trying to maneuver under a blanket). This air/gas remains in the abdomen for some time, causing bloating and pain.

One set of researchers are finding that less air/gas (7 mmHg vs 14 mmHg) can get the job done just as well and ease the recovery of living kidney donors too.


…low pressure resulted in a significantly higher urine output  (23 ± 35 vs. 11 ± 20 mL/h), lower cumulative overall pain score after 72 hours (9.4 ± 3.2 vs. 13.5 ± 4.5), lower deep intra-abdominal pain score (11 ± 3.3 vs. 7.5 ± 3.1), and a lower cumulative overall referred pain score (1.8 ± 1.9 vs. 4.2 ± 3).


So, for you prospective LKDs out there, consider asking your surgeon just *how much* air they’re pumping in there.
