Bipolar plasmakinetic transurethral resection of the prostate vs. transurethral enucleation and resection of the prostate: pre- and postoperative comparisons of parameters used in assessing benign prostatic enlargement

Introduction : Transurethral enucleation and resection of the prostate (TUERP) may offer a better treatment for benign prostatic enlargement. We compared the perioperative parameters and outcome following bipolar plasmakinetic transurethral resection of the prostate (TURP) and TUERP. Methods : Data from two independent institutions were reviewed retrospectively. 50 and 45 consecutive patients were enrolled in the TURP and TUERP groups, respectively. Preand postoperative parameters, including prostatic specific antigen (PSA), prostate volume (PV), International Prostate Symptom Score (IPSS), quality of life (QOL) score, uroflowmetry and prostate volume (PV), were compared. Results : Age at surgery, preoperative PSA (5.8 +/− 4.0 versus 7.6 +/− 5.9 ng/ml) and PV (55.8 +/− 31.6 versus 53.2 +/− 26.8 g) showed no significant difference (p-value greater than 0.05). However, postoperative PSA (2.8 +/− 3.0 versus 0.8 +/− 0.4 ng/ml; p-value less than 0.05) and PV (15.2 +/− 7.7 versus 10.5 +/− 5.4 g; p-value less than 0.01) differed significantly between the TURP and TUERP groups, respectively. There were no significant differences in IPSS, QOL, and Qmax between the two groups during follow-up (p-value is 0.62, 0.68 and 0.13, respectively). However, for the TUERP group, the postoperative post-void residual urine volume (PVR) was significantly better (13.8 +/− 19.5 versus 25.2 +/− 18.7 ml; p-value less than 0.01). Conclusion: The TUERP technique achieved more complete resection than TURP, with a smaller post procedure PV and lower PSA and PVR after surgery. This may predict better long-term results for patients who had TUERP.
