Abstract: To study the changes of blood glucose, sodium, chloride, potassium and hematocrit (HCT) in patients undergoing plasmakinetic transurethral resection of the prostate（PKRP）in the perioperative period. Methods90 patients undergoing PKRP and 87 patients undergoing transurethral resection of the prostate(TURP) were enrolled in this study, and blood samples were phlebotomized for measurements of blood glucose, sodium, chloride, potassium and hematocrit 1 day before the operation (T1), 20 minutes after the operation (T2), right after the operation (T3), and 4 hours after the operation (T4). ResultsIn the PKRP group, there was a significant decrease of HCT, while there was a significant increase of hemoglucose at T2, T3 and T4; there were no significant changes of the other parameters. While in the TURP group, there was a significant decrease of hemosodium and hemochloride and a significant increase of hemoglucose compared with the PKRP group. ConclusionPKRP is a safe method with little interference of blood glucose, sodium, chloride, potassium and HCT in the perioperative period, and it reduces the incidence of cardiovascular events and prevents the transurethral resection syndrome(TURS).
