Bipolar plasma vaporization versus monopolar TUR and "cold-knife" TUI in secondary bladder neck sclerosis - an evidence based, retrospective critical comparison in a single center clinical setting.

INTRODUCTION: A long term, retrospective study was performed aiming to outline a critical comparison concerning the efficacy, safety and durability of the bipolar plasma vaporization (BPV), standard monopolar transurethral resection (TUR) and "cold-knife" "star" transurethral incision (TUI) in secondary bladder neck sclerosis (BNS) cases. MATERIALS & METHODS: Of the 126 patients included in the trial based on maximum flow rate (Qmax) below 10 mL/s and International Prostate Symptom Score (IPSS) over 19, classical resection was performed in 46 cases, "cold-knife" TUI in 37 cases and bipolar vaporization in 43 patients. The evaluation protocol comprised IPSS, QoL (quality of life) score, Qmax and PVR (post-voiding residual urinary volume) assessment performed at 1, 3, 6, 12, 18 and 24 months after the initial intervention. RESULTS: Significant intraoperative complications (capsular perforation - 8.7%; bleeding - 4.3%) occurred secondary to monopolar resection. "Star" TUI was the fastest technique, followed by plasma-button vaporization (7.2 and 11.4 versus 16.5 minutes). BPV and TUI patients benefitted from the shortest catheterization periods (0.75 and 1 versus 2.0 days) and hospital stays (1.0 and 1.25 versus 2.0 days). Immediate postoperative adverse events consisted of hematuria (6.5% of the TUR cases) and acute urinary retention (8.1% of the TUI group). Significantly higher long term BNS recurrence rates requiring re-treatment were established in the TUI (18.7%) and TUR (12.8%) series by comparison to BPV (5.4%). Among patients that completed the follow-up protocol, equivalent IPSS, QoL, Qmax and PVR features were determined in the 3 study arms. CONCLUSIONS: The plasma vaporization approach was confirmed as a successful match to conventional TUR and "cold-knife" TUI in terms of surgical safety profile, postoperative recovery, therapeutic durability and urodynamic and symptom score parameters.

Bipolar plasma vaporization in secondary bladder neck sclerosis--initial experience with a new technique.

INTRODUCTION: Secondary bladder neck sclerosis (BNS) represents one of the most common long-term complications after prostate surgical treatment. In this retrospective study, we aimed to evaluate our initial experience concerning the bipolar plasma vaporization (BPV) performed in patients with secondary BNS and to assess the efficiency, safety and short-term postoperative results of this approach. MATERIALS & METHODS: Between May 2009 and May 2010, a total of 30 male patients with BNS underwent BPV and were followed for a period of 6 months. BNS was secondary to monopolar transurethral resection of prostate (TURP) in 19 cases, to open surgery for BPH (open prostatectomy) in 8 cases and to radical prostatectomy for prostate cancer in 3 cases. The follow-up protocol included the International Prostate Symptom Score (IPSS), quality of life score (QoL), maximum flow rate (Qmax) and post-voiding residual urinary volume (RV) evaluated at 1, 3 and 6 months after surgery. RESULTS: BPV was successfully performed in all cases. All patients were able to void spontaneously and were continent after catheter removal. The mean operating time was 9 minutes, the mean catheterization period was 18 hours and the mean hospital stay was 24 hours. Preoperatively and at 1, 3 and 6 months after surgery, the mean values for Qmax and RV were 7.2 ml/s and 110 ml, 23.9 ml/s and 20 ml, 23.8 ml/s and 28 ml, and 23.4 ml/s and 26 ml, respectively. Before surgery and at 1, 3 and 6 months, the IPSS and QoL scores were 22.6 and 4.1, 3.4 and 1.2, 3.6 and 1.4, and 3.7 and 1.4, respectively. CONCLUSIONS: BPV represents a valuable endoscopic treatment alternative for secondary BNS with good efficacy, reduced morbidity, fast postoperative recovery and satisfactory follow-up parameters.

OBJECTIVES: The trial evaluated a new endoscopic treatment alternative for large benign prostatic hyperplasia (BPH) cases, the bipolar plasma enucleation of the prostate (BPEP), in terms of surgical efficiency, safety and short-term postoperative results. MATERIALS AND METHODS: A total of 30 patients with prostates larger than 80 ml were included in the study. All cases were investigated preoperatively and at 1 and 3 months after surgery by international prostate symptoms score (IPSS), quality of life score (QoL), maximum flow rate (Q(max)) and abdominal and transrectal ultrasonography. RESULTS: All procedures were successfully performed. The enucleation and morcellation times were 69.8 minutes and 18.5 minutes, while the morcellated tissue weight was 77 grams. The mean hemoglobin drop was 0.8 g/dl and the mean catheterization period and hospital stay were 26.5 hours and 2.3 days. The rate of early irritative symptoms was 10%. At 1 and 3 months, significant improvements were determined concerning the IPSS (5.3 and 4.8), QoL (1.2 and 1.1) and Q(max) (25.9 and 25.1 ml/s). CONCLUSIONS: BPEP represents a promising endoscopic approach in large BPH cases, characterized by good surgical efficacy, reduced morbidity, fast postoperative recovery and satisfactory follow-up parameters.

TURP for BPH. How large is too large?

BPH remains one of the most common diseases that the urologist has to manage. The last decade brought numerous new techniques, aiming to improve the minimally invasive approach to BPH, but, for the moment, none had changed the place of TURP as the gold standard treatment for medium sized prostates. Based on a large personal experience, the authors present a study in which TURP is used for prostates over 80 ml, the cutoff point set by the guidelines of the European Association of Urology. The rationale for this study is that many situations require minimally invasive treatment, based on the express request of the patient, other conditions that makes open surgery very difficult or impossible, or the need for a quick discharge in an overcrowded service. The aim of the study was to prove that TURP is safe and effective even in larger prostates. The technique used is basically the classic one, with minor tactical alterations in some cases. Some cases required a two-stage approach, but offered good functional results after the first stage. The results proved that, with a good technique, a skilled urologist might achieve the same results by using TURP or open surgery for large sized prostates.
