Visceral Pain From the Upper Urinary Tract - a Trial on the Effect of Morphine and Oxycodone in Patients Undergoing PCNL
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.
