A hybrid technique using bipolar energy in transurethral prostate surgery : a prospective , randomized comparison . PURPOSE We assessed the efficacy and safety of transurethral resection and vaporization with bipolar PlasmaKinetic energy . MATERIALS AND METHODS During a 2-year period 101 men with benign prostatic hyperplasia were randomly assigned to PlasmaKinetic surgery or standard transurethral prostate resection ( TURP ) . Patient demographics , indications for surgery , preoperative and postoperative International Prostate Symptom Score , uroflowmetry scores , operative time , catheterization duration , hospital stay and complication rates were compared . RESULTS Complete data on 96 patients with a mean age +/- SD of 69.1 +/- 6.1 years was available at a mean followup of 18.3 +/- 6.7 months ( range 12 to 23 ) . In the PlasmaKinetic and TURP groups mean operative time was 40.3 +/- 11.4 ( range 30 to 60 ) and 57.8 +/- 13.4 minutes ( range 45 to 75 ) , respectively ( p < 0.01 ) . The mean volume of saline irrigation during the PlasmaKinetic procedure was significantly lower than that of hyperosmolar solution irrigation during TURP ( p < 0.05 ) . Patients in the PlasmaKinetic and TURP groups were catheterized a mean of 2.3 +/- 0.7 ( range 2 to 4 ) and 3.8 +/- 0.7 days ( range 3 to 5 ) , respectively ( p < 0.05 ) . The mean improvement rate from baseline at month 12 in International Prostate Symptom Score and the maximal urinary flow rate was similar in the 2 groups . Severe irritative symptoms were the most common complaints after PlasmaKinetic surgery , as observed in 6 cases ( 12.2 % ) . Recatheterization was necessary in 3 cases ( 6.1 % ) cases in the PlasmaKinetic group and in 1 ( 2.1 % ) in the TURP group . During followup urethral stricture formation was observed in 3 patients ( 6.1 % ) cases in the former group and in 1 ( 2.1 % ) in the latter group ( p = 0.002 ) . Reoperation was required in 2 ( 4.1 % ) and 1 ( 2.1 % ) cases in the PlasmaKinetic and TURP groups , respectively . CONCLUSIONS : Transurethral surgery with PlasmaKinetic bipolar energy seems to be a promising alternative to prostatic tissue removal with shorter operative , catheterization and hospitalization times , although increased rates of postoperative irritative symptoms and urethral stricture formation must be further evaluated .
