The purpose of this study is to investigate the effect of oxynorm versus morphine after operation for kidney stone (PCNL). In addition the relationship between pain symptoms and referred sensory and trophic changes will be examined in the patients before and after the operation.Finally a blood sample is analysed to investigate pharmaca-genetics.

Arms Assigned Interventions
Active Comparator: oxycodone Drug: oxycodone
intravenous according to patients weight, pn.
Other Name: oxynorm N02A A05
Active Comparator: morphine Drug: morphine
intravenous administration according to patients weight, pn.
Other Name: morphine SAD N02 AA 01

Detailed Description:

Primary outcome: the amount of opioid (morphine or oxynorm) used the first 4 hours postoperatively.

Secondary outcome: side effect to the opioids, pain score, pain threshold to electrical stimulation and pressure before and after operation, pharmacogenetics, size of referred pain area.
