The hemostatic properties of transurethral plasmakinetic resection of the prostate: comparison with conventional resectoscope in an ex vivo study.
OBJECTIVE
To compare the hemostatic properties of transurethral plasmakinetic resection of the prostate (PKRP) and standard transurethral resection of the prostate (TURP) ex vivo, as perioperative bleeding is still regarded as one of the major complications of transurethral prostatectomy.


METHODS
Isolated normal saline (NS)-perfused porcine kidneys were used to determine the hemostatic efficacy of PKRP and TURP. The perfusion fluid loss was semiquantitatively measured in relation to tissue ablation for the two techniques and specimens were evaluated histologically.


RESULTS
The PKRP group had a significantly smaller loss of NS than the TURP group (4.16 +/- 1.25 and 6.39 +/- 1.05 g/min, respectively, p < 0.01). Compared with the measurements with TURP, the depths of the coagulation zones with PKRP were significantly larger (225.09 +/- 35.77 and 146.84 +/- 18.91 microm, respectively, p< 0.01).


CONCLUSIONS
PKRP ex vivo was associated with significantly better hemostasis than TURP.
