Retroperitoneoscopic nephrectomy in overweight and obese Japanese patients: complications and outcomes.
BACKGROUND
The objective of the present study was to evaluate the safety of retroperitoneoscopic nephrectomy (RN) in obese Japanese patients.


METHODS
We retrospectively reviewed 190 consecutive RN procedures performed from May 2002 to May 2006. We divided patients into an obese group (BMI >or=25, n = 54) and a normal group (BMI <24.9, n = 136). Operation time, estimated blood loss, and complications were compared between the two groups.


RESULTS
The mean operation time was longer in the obese group than in the normal group (203 vs. 184 min, respectively; p = 0.029). The mean estimated blood loss in the obese and normal groups was 127 and 91 ml, respectively. This difference was not significant (p = 0.39). There was no significant difference in complications and the open conversion rate between the two groups.


CONCLUSIONS
Although the operation time in obese patients was slightly longer than in non-obese patients, RN in obese patients was safely performed.
