“…Also in our trial, the B-TUVP had lesser mean hemoglobin drop than B-TURP (0.53 vs. 1.39g/dL) due to superior hemostasis and coagulation (12,34). The published experiences reported the mean postoperative hospitalization and catheterization periods of 1.4-2.08 and 2.2-3.54 days for bipolar vaporization (12,20,44,45). No significant differences were seen in catheterization and hospitalization duration between bipolar electrovaporization (1193 minutes, 1.45 days) and TURP (1007 minutes, 1.5 days) in Dunsmuir and co-workers trial (16 (17)).…”

ARTICLE INFO ______________________________________________________________ ______________________Objective: To compare the outcomes of bipolar transurethral vaporization of the prostate (TUVP) with bipolar transurethral resection of the prostate (TURP). Materials and Methods: In a prospective randomized trial, 88 patients with moderate to severe lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH) underwent bipolar TUVP (N = 39) or bipolar TURP (N = 49) from October 2010 to November 2011. The inclusion criteria were age > 50 years, prostate volume of 30-80mL, serum PSA < 4ng/mL, IPSS ≥ 20, Q max ≤ 10mL/s and failed medical therapy. The perioperative and postoperative outcomes were evaluated and the IPSS and Q max were assessed preoperatively and 3 months after procedure in all cases. Results: Both groups were similar in patient age, prostate volume, preoperative IPSS and Q max . The TUVP group had significantly lower mean values of operative time, hospital stay, catheterization period, irrigation fluid volume and serum hemoglobin, creatinine, sodium and potassium changes compared with TURP group. No significant differences were seen between two groups regarding complications (TUVP = 10.3%; TURP = 12.2%) and modified Clavien classification of complications. No TUR syndrome, obturator reflex or epididymitis occurred in both groups. Re-hospitalization and transfusion due to clot retention (N = 2) and urethral stricture (N = 1) were reported only in the TURP group. Three patients experienced urinary retention after catheter removal in the TUVP group. Two patients were re-catheterized temporarily and one patient required repeat bipolar TUVP. Three months after surgery, two groups had significant improvement in IPSS and Q max . But the TUVP group had significantly lower IPSS and higher Q max than TURP group. Conclusions: Bipolar TUVP is a safe, effective and low cost procedure among minimally invasive surgeries of BPH. Compared with bipolar TURP, the bipolar TUVP had similar complications, better perioperative and postoperative outcomes, superior hemostasis and higher efficacy.

“…The operating time had the means of 61 and 63 minutes for B-TUVP and the median of 55 minutes for bipolar plasmakinetic electrovaporization in the published experiences (12,20,45). In Dunsmuir and co-workers trial, the bipolar electrovaporization and TURP had similar operation time (33 vs. 26 minutes, P = 0.78) (16).…”

Introduction and Objectives: Bipolar plasma vaporization (BPV) has been introduced as an alternative to transurethral resection of the prostate (TURP). Promising short-term results, but inferior mid-term results compared to TURP have been reported following first-generation bipolar electrovaporization. Outcome data following second-generation BPV are still scarce. The aim of this investigation was to evaluate the intra-and postoperative outcomes of contemporary BPV in a center with long-standing expertise on laser vaporization of the prostate. Methods: A consecutive series of 83 patients undergoing BPV in a tertiary referral center was prospectively evaluated. The investigated outcome parameters included the maximum flow rate (Qmax), postvoid residual volume, International Prostate Symptom Score (IPSS)/quality of life (Qol), and prostate-specific antigen (PSA) tests. Follow-up investigations took place after 6 weeks, 6 months, and 12 months. The Wilcoxon signed-rank test was used to compare pre-and post-treatment parameters. Results: The median (range) preoperative prostate volume was 41 mL (17-111 mL). The preoperative IPSS, Qol, Qmax, and residual volume were 16 (2-35), 4 (0-6), 10.1 mL/s (3-29.3 mL/s), and 87 mL (0-1000 mL), respectively. One third of the patients were undergoing platelet aggregation inhibition (PAI). No intraoperative complications occurred. Postoperatively, 13 patients (15.7%) had to be recatheterized. Three patients (3.6%) had clot retention and 28 patients (34%) reported any grade of dysuria. After 6 weeks, all outcome parameters improved significantly and remained improved over the 12-month observation period [IPSS: 3 (0-2); Qol: 1 (0-4); Qmax: 17.2 mL/s (3.2-56 mL/s); residual volume 11 mL (0-190 mL)]. The PSA reduction was 60% at study conclusion. Three patients (3.6%) developed a urethral stricture and four patients (4.8%) bladder neck sclerosis. Re-resections were not necessary. Conclusions: Contemporary BPV is a safe and efficacious treatment option even for patients undergoing PAI. Early urinary retention and temporary dysuria seem to be specific side effects of the treatment. Bleeding complications are rare. Long-term follow-up is needed to confirm these promising short-term results.

“…The positive and negative poles are on the same axis and are isolated from each other by a ceramic connecting piece. 7 The Plasmakinetic Generator (Gyrus Medical) generates strong, pulsatile, bipolar energy, which generates the working temperature on the cutting tool, permitting maximum tissue dissection with minimum collateral damage. In addition to allowing effective cutting, it has been constructed to achieve optimum hemostasis and prevent adherence to the tissue.…”

We compared bipolar and monopolar TURP in a prospective controlled study at two urology centers. The objective of the study was to establish whether there were differences between the two methods with regard to frequency of the transurethral resection (TUR) syndrome, amount of fluid absorbed during surgery, risk of hemorrhage, duration of postoperative catheterization and duration of hospitalization. The duration of surgery, improvement in maximum flow rate (Q-max), residual urine volume, International Prostate Symptom Score (IPSS) and Quality of Life (QoL) score were also compared. Overall, our study showed that there were no major differences between bipolar and monopolar TURP. During follow-up, the clinical efficacy of bipolar TURP has been maintained to the same degree as with the traditional method, with no significant differences for Q-max, IPSS and QoL scores after 1 year. Although the risk of developing TUR syndrome seemed to be smaller with bipolar resection (serum sodium change bipolar versus monopolar: þ 1.2 versus À0.1 mmol l À1 ), the bleeding tendency with both methods was the same (14.0 g l À1 hemoglobin loss after 1 day in both groups). On the basis of our findings, we think that the monopolar technique has still a place in TURP.
