Evaluation of perioperative risk factors for bladder neck contracture after bipolar transurethral resection of the prostate.

Bladder neck contracture after transurethral resection of the prostate is a common complication but without clear predisposing factors. In this prospective study, we evaluated the perioperative risk factors associated with bladder neck contracture after bipolar transurethral resection of the prostate. The study included 391 patients who were admitted for bipolar transurethral resection of the prostate between October 2020 to October 2023 by three experienced surgeons. Forty three patients had bladder neck contracture and their perioperative parameters were compared with randomly chosen 172 patients without bladder neck contracture. There were no significant differences between the studied groups regarding the general and present history characteristics. Re-catheterization after transurethral resection of the prostate, post-operative recurrent urinary tract infection, resection speed, and associated urethral stricture were significantly higher among the bladder neck-contraction group (P < 0.05), while total PSA, total prostate weight, post void residual urine volume, resected gland weight, resection time and catheter duration were significantly lower among the bladder neck-contraction group (P < 0.05). Bladder neck contracture after bipolar transurethral resection of the prostate is more common among patients with small fibrotic prostate, low total PSA, small post- void residual urine volume, those with a higher incidence of post-operative recurrent urinary-tract infection and patients with a higher incidence of re-catheterization after transurethral resection of the prostate.

Application of Urethral Contrast Computed Tomography Three-Dimensional Imaging in the Postoperative Assessment of Prostate Hyperplasia.

This study assesses the morphological effectiveness of benign prostatic hyperplasia (BPH) surgery using multislice spiral computed tomography three-dimensional imaging (CT3D) with urethral contrast. Twenty-five male patients with BPH and bladder outlet obstruction (BOO) who underwent bipolar transurethral resection of the prostate were selected. Preoperative and postoperative CT3D indicators of retrograde and voiding cystourethrography, including bladder neck diameter, length of the posterior urethra, and degree of prostate protrusion into the bladder and upper and lower diameter of the prostate were used to assess bladder neck and posterior urethra morphology and BOO severity. In addition, preoperative and postoperative International Prostate Symptom Scores and maximum urine flow rates were compared. Postoperative CT3D was used to evaluate changes following obstruction relief postsurgery. Preoperative CT3D indicated significant BOO, whereas postoperative imaging showed improved patency but with irregular posterior urethral lumens and varying degrees of residual glandular tissue. Comparative analysis of preoperative and postoperative bladder outlet metrics revealed significant changes (p < .05). Urethral contrast CT3D effectively visualizes the prostate, bladder neck, and prostatic urethra. It quantifies changes in the urethral lumen postsurgery, correlating the extent of posterior urethral lumen spaciousness with urinary flow rates.

Beware of Bipolar Transurethral Resection of Prostate in Patients with Previously Inserted Metallic Prostate Stapling Devices

Metallic prostate stapling (e.g., UroLift) is a minimally invasive treatment option for men with bladder outlet obstruction from benign prostatic hyperplasia (BPH). While it provides rapid relief and preserves sexual function, unexpected interactions with other medical devices can compromise surgical procedures. In this letter, we highlight five cases where stapled metallic implants resulted in damage to bipolar energy device during transurethral resection of the prostate (TURP) and stimulation of obturator nerve. Laser may also reflect off metallic prostate implants which can result in laser equipment malfunction. Monopolar TURP should be considered in patients with existing metallic prostate implants who need further transurethral surgery for obstructive BPH to prevent bipolar instrument damage and obturator kick.

Reoperation Rate for Residual/Regrowth Adenoma Following Transurethral Interventions for Benign Prostatic Enlargement: Results from a Systematic Review and Meta-Analysis of Comparative Randomized Studies.

Objective: To perform a systematic review to assess the incidence of reoperation rate for residual/regrowth adenoma after transurethral surgeries for benign prostatic enlargement. Materials and Methods: A systematic literature search was performed on November 12, 2023, using Cochrane Central Register of Controlled Trials, PubMed, and Scopus. We only included randomized studies comparing monopolar (M)/bipolar (B) transurethral resection of the prostate (TURP) vs ablation vs enucleation procedures. Incidence of reoperation was assessed using the Cochran-Mantel-Haenszel Method and reported as risk ratio (RR), 95% confidence interval (CI), and p-values. Statistical significance was set at p < 0.05. Evidence synthesis: Forty-eight studies were included. Six studies compared enucleation vs TURP, 41 ablation vs TURP, and 1 study enucleation vs ablation vs TURP, encompassing 457 patients in enucleation, 2259 in ablation, and 2517 in the TURP group. The pooled incidence of reoperation was 6.2%, 0.7%, 2.3%, and 4.3% after ablation, enucleation, M-TURP, and B-TURP, respectively. Meta-analysis showed that the incidence of reoperation was significantly lower in the enucleation group (RR 0.28, 95% CI 0.10-0.81, p = 0.02), but the difference accounted only in studies with follow-up between 1 and 3 years (RR 0.18, 95% CI 0.04-0.85, p = 0.03). The incidence of reoperation was significantly lower in the enucleation compared with the B-TURP group (RR 0.14, 95% CI 0.03-0.77, p = 0.02). Meta-analysis showed that the incidence of reoperation was significantly higher in the ablation group (RR 1.81, 95% CI 1.33-2.47, p = 0.0002), but there was no difference in studies with follow-up up to 1 year (odds ratio 1.78 95% CI 0.97-3.29, p = 0.06) longer than 5 years (RR 2.02, 95% CI 0.71-5.79, p = 0.19). The incidence of reoperation was significantly higher in the ablation compared with the M-TURP group (RR 1.91, 95% CI 1.44-2.54, p < 0.0001). Conclusions: In mid-term follow-up, reoperation rate for residual/regrowth adenoma was significantly lower after enucleation, although was significantly higher after ablation compared with TURP.

Comparison of Bipolar and Monopolar Transurethral Resection of the Prostate, Functional Outcomes and Analysis of Factors Predictive of Complications: A Prospective Study

Introduction: In Morocco, RTUP-m is considered the gold standard for the surgical treatment of prostate adenomas, recommended for prostates with a volume suitable for resection in less than 60 minutes. Additionally, the challenge arises when dealing with patients on antiplatelet or anticoagulant medications due to the associated risk of bleeding, hence the significance of RTUP-b. The objective of our study is to compare the functional outcomes and immediate postoperative complications between these two techniques and to identify predictive factors for complications. Methods: This is a prospective randomized study conducted between January 2022 and September 2022. The variables age, BMI, surgical indication, transrectal prostate volume, ASA classification (American Society of Anesthesiologists), previous pharmacological treatments, IPSS score, quality of life index (QLI), maximum flow rate (Qmax) and postoperative complications were collected. The Chi2 test and Student's t-test were used for statistical analysis. Results: Sixty-nine consecutive patients were included, 38 patients in the monopolar TURP group and 31 in the bipolar TURP group. Both groups were homogeneous in their baseline characteristics. The overall pre-surgical IPSS/QLI/Qmax score was 24,03/4,73/9,47. Functional results at 1st and 3rd month are shown in Table 1. For complications, see Table 2 and 3. These differences were not statistically significant (p = 0,427): the most frequent were hematuria (9,4%) and febrile urinary tract infections (9,4%). Only one patient presented hyponatremia due to glycocol reabsorption in the monopolar group. All complications were Clavien 1 or 2. We found no significant differences between the two groups with regard to complications or their predictive factors. Conclusion: Analysis of our data over the first three months reveals no differences between the two techniques in terms of functional results and postoperative complications, and there are no predictive .........

Outcome of Monopolar versus Bipolar Transurethral Resection of Prostate

Introduction: Transurethral resection of the prostate is the gold standard surgical treatment for benign prostatic hyperplasia with the lower urinary tract symptoms. Bipolar system is a new in technology to lower the adverse effects of monopolar system. This study was designed to find out clinic-demographic data and peri-operative outcomes of the monopolar versus bipolar transurethral resection of prostate. Methods: This prospective comparative study was conducted from June 2022 to March 2023, in the Department of Urology of Bir Hospital, National Academy of Medical Sciences, Nepal. Ethical approval of research was taken from Institutional Review Board, NAMS: Ref No. 735/2079/80. Microsoft Excel was used for descriptive analysis for clinic-demographic and outcome variable data, were presented in frequencies and percentages and their relation were analyzed by chi-square test/fisher’s exact test. A p-value of &lt;0.05 statistically significant. Result: A total 80 patients were compared, bipolar(40 cases) and monopolar(40 cases). There were no differences in the incidence of hyponatremia, clot retention and evacuation rate, re-catheterization rate, mean hemoglobin loss, and mean length of hospital stay. The longer duration of operation time (&gt;60 min) was observed in bipolar transurethral resection ( p=0.001). The transurethral resection syndrome was found only in M-TURP. Conclusion: Both monopolar and bipolar transurethral resection of prostate showed no statistical differences in the amount of resected prostatic tissue, the incidence of hyponatremia, length of hospital stays, blood transfusion rate, re-catheterization rate, clot retention and evacuation rate. The shorter duration of surgery and the trans-urethral resection syndrome was observed in M-TURP.

Two-year follow-up comparing Rezūm therapy versus bipolar transurethral resection of the prostate for treating benign prostatichyperplasia. A prospective randomized study.

Comparison of the efficacy and safety of Rezūm therapy and bipolar transurethral resection of prostate (B-TURP) for the management of benign prostatic hyperplasia (BPH) of 50-120 g size. One hundred patients with BPH who met the inclusion criteria were included and split into two equal groups to undergo Rezūm therapy or B-TURP. The two groups were compared for efficacy using international prostate symptom score (IPSS), quality of life (QoL), maximum urinary flow rate (Qmax), operative time, catheter time, hospital stay, post-void residual urine (PVR), prostate-specific antigen (PSA), and residual prostate size and safety using the incidence of complications. Rezūm significantly ameliorated IPSS from the baseline score by 55.3%, QoL by 50%, Qmax by 62.5%, International Index of Erectile Function (IIEF) by 7.1%, PVR by 50%, residual prostate size by 28.1% and PSA by 42% at 2 years. Meanwhile, the improvement in B-TURP was significantly higher than Rezūm group, Rezūm therapy had a significantly shorter duration of operative time and hospital stay. Also, it had fewer complications in comparison with B-TURP. Rezūm is a minimally invasive procedure that provides significantly improved symptomatic relief of BPH and quality of life with preservation of erectile and ejaculatory functions. However, it is not as effective as B-TURP.

Assessing the Safety and Effectiveness of Bipolar Technology in Transurethral Prostate Resection: A study in a Tertiary Care Private Hospital

Background: Benign enlargement of prostate (BEP) is a common affliction among aging males, predominantly emanating from the transition zone of the prostate, resulting in lower urinary tract symptoms. Despite the availability of diverse treatment modalities, transurethral resection of prostate (TURP) has conventionally served as a benchmark intervention. Recently, there has been a growing interest in bipolar energy techniques, spurred by their potential advantages in mitigating complications such as TUR syndrome and surgical bleeding. Objectives: The main aim of the study to evaluate the safety profile (including serum sodium and hemoglobin reductions, clot retention, TUR syndrome, catheterization duration, and hospital stay) and efficacy (resection rate, maximum flow rate increase, and International Prostate Symptom Score reduction) within the bipolar technique for the TURP. Methods &amp; Materials: A prospective observational study was conducted at the Department of Urology, Square Hospitals Ltd, Dhaka, Bangladesh, spanning December 2020 to November 2021. The study employed comprehensive preoperative assessments, including bipolar transurethral resection of the prostate (B-TURP) using Olympus ESG-400 energy platform. Surgical parameters, postoperative monitoring, and statistical analysis were meticulously executed to evaluate outcomes and complications for symptomatic benign enlargement of prostate. Results: In a sample of 50 individuals undergoing bipolar transurethral resection of the prostate (B-TURP), the distribution of ages revealed 66.97±7.95 years as the bipolar system's average age, ranging from 53-82 years. The majority resided in urban areas (62%), with family income predominantly in the 25000-50000 bracket (42%). Preoperative baseline variables, including IPSS, Qmax, serum hemoglobin, and sodium levels, exhibited similar values between groups. Intraoperatively, the mean resection rate was 0.56±0.16 gm/min. Postoperatively, B-TURP resulted in a slight ......

Comparison of the results of bipolar transurethral enucleation and resection of the prostate with and without morcellation in treatment of benign prostatic hyperplasia

Objective: To compare the result of bipolar transurethral enucleation and resection of the prostate with morcellation (B-TUERP-M) and without morcellation (B-TUERP) in treatment of benign prostatic hyperplasia. Materials and Methods: This was a prospective single centre cohort study of 101 patients with prostate enlargement of more than 60 ml who underwent B-TUERP by a single surgeon between January 2020 and June 2022. Patients were divided into two groups, a B-TUERP group of 49 patients and a second group of 52 patients classed as B-TUERP-M. The perioperative outcomes followed up at 1, 3 and 6 months after surgery were evaluated. Results: There were no significant differences in the preoperative parameters of the two groups. Comparisons between the two groups showed a shorter operative time (63.94 ± 12.01 vs 77.77 ± 11.80 min, p-value 0.000), more resected prostate tissue (65.73 ± 14.67 vs 60.73 ± 5.45 gm, p-value 0.027) and a higher post-operative hematocrit level (35.16 ± 3.97 vs 33.18 ± 3.22%, p-value 0.007) in the patients who underwent B-TUERP with morcellation. At 6 months after the procedure, better results were found in patients who had undergone B-TUERP-M regarding urine flow rate (26.33 ± 5.33 vs 20.66 ± 5.08 ml/sec, p-value 0.000), post-void residual urine volume (24.19 ± 10.93 vs 36.04 ± 16.90 ml, p-value 0.000), post-operative PSA (0.72 ± 0.43 vs 1.22 ± 0.54 mg/ml, p-value 0.000) and International Prostate Symptom Scores (5.01 ± 1.36 vs 5.71 ± 1.33, p-value 0.001). Conclusion: Better outcomes occurred following B-TUERP with morcellation with regard to operative time, resection weight of prostatic adenoma, post-operative urine flow rate, Post-void residual urine volume, PSA and International Prostate Symptom Score than in patients treated with B-TUERP without morcellation.

The Safety and Efficacy of Bipolar Plasma-Kinetic Transurethral Resection of The Prostate in Patients Taking Low-Dose Aspirin.

To explore the safety and efficacy of bipolar plasma-kinetic transurethral resection of the prostate in patients taking low-dose aspirin. Benign prostatic hyperplasia (BPH) patients who underwent surgical treatment from November 2018 to May 2020 were retrospectively analyzed, and divided into two groups according to whether taking 100mg aspirin daily aspirin or not. The perioperative indexes, complications and sequelae also were used to evaluate safety. The efficacy was evaluated by the functional outcomes in 3,6,12 months. There were no statistical differences in the baseline characteristics or perioperative indicators and complications and sequelae, except for a longer operative time(90.49 ± 14.34 vs 84.95 ± 15.49; 95%CI: 0.26-10.83; P = .040) and a shorter hospital stay time(HST) (8.52 ± 1.55 vs 9.09 ± 1 .50; 95% CI: 0.21-1.11; P = .042) in the non-aspirin group. During the 12-months follow-up period, the functional outcomes of the two groups were significantly improved except International Index of Erectile Function (IIEF-5). Based on our research results, PKRP a safe and effective method for patients with BPH who taking 100mg aspirin daily.

The effect of tranexamic acid on perioperative blood loss in transurethral resection of the prostate: A double-blind, randomized controlled trial.

Bleeding and bleeding-related complications remain common after bipolar transurethral resection of the prostate (TURP) for benign prostatic hyperplasia. This may possibly lead to prolonged postoperative irrigation, catheterization, and hospital stay. The objective of this trial was to evaluate the effect of high-dose tranexamic acid (TXA) on perioperative blood loss in patients treated with bipolar TURP for prostate sizes between 30 and 80 g. We conducted a single-center, prospective, double-blind, randomized controlled trial. Eighty patients were screened for inclusion between March 2020 and January 2023. After exclusion, 65 patients were randomized in two comparable groups. The TXA group (31 patients) received a TXA intravenous loading dose of 10 mg/kg over 30 min before induction, followed by a maintenance dose of 5 mg/kg/h over 12 h. The placebo group (34 patients) received an equal dose of saline infusion. We measured age, weight, preoperative prostate size, anticoagulant use, 5-alpha reductase inhibitor use, preoperative urinary tract infection, American Society of Anesthesiologists score, difference in pre- and 24 h postoperative hemoglobin and hematocrit levels, operative time, resected adenoma weight, duration of postoperative irrigation, total amount of postoperative irrigation fluid, indwelling catheter time, duration of hospital stay, blood transfusion rate, and 4-week complication rate. Baseline characteristics in both groups were comparable. Postoperative hemoglobin decrease in TXA versus placebo group was 1 versus 1.6 mg/dL, respectively (p = 0.04). In addition, the amount of postoperative irrigation fluid (10.7 vs. 18.5 L), irrigation time (24.3 vs. 37.9 h), catheterization time (40.8 vs. 53.7 h), and hospital stay (46.9 vs. 59.2 h) were statistically significant in favor of TXA use. No blood transfusions were carried out. Four-week complication rate was comparable between the two groups. Perioperative high-dose TXA seems beneficial in reducing hemoglobin loss, postoperative irrigation, catheterization time, and hospital stay in bipolar TURP for prostate sizes between 30 and 80 g, without increased risk of TXA-related thromboembolic events.

Combination of 180-W GreenLight XPS laser and bipolar transurethral resection of prostate for the treatment of large prostates beyond 100ml: a novel hybrid technique.

The aim of this study was to evaluate the safety and efficacy of the 180-W GreenLight laser (GL) XPS™ plus bipolar transurethral resection of the prostate (TURP) for the treatment of a prostate volume (PV) beyond 100ml. From January 2014 to December 2022, 79 patients with PV > 100ml who underwent GL-XPS plus bipolar TURP were enrolled. The median follow-up time was 13.7months. The International Prostate Symptom Score (IPSS), PV, uroflow study, post-void residual (PVR) volume, and prostate-specific antigen (PSA) before and after the operation were recorded. Subgroup analysis was performed to compare the outcomes between the patients with follow-up times of < 36months and > 36months. Statistically significant improvements in all the postoperative parameters were observed in both < 36months and > 36months groups. There was no blood transfusion or transurethral resection (TUR) syndrome in this series. Most of all, a second TURP was unnecessary during the follow-up. Only one (1.3%) Clavien-Dindo grade 3b complication was noted. The hybrid technique of 180-W XPS™ GreenLight laser plus bipolar TURP can be safely and efficiently performed on patients with a prostate volume of > 100ml.

Personalized Approach to the Surgical Treatment of Benign Prostatic Hyperplasia by Bipolar Transurethral Resection of the Prostate

Comparison of holmium laser, bipolar and conventional monopolar transurethral resection of bladder tumour in primary non-muscle invasive bladder cancer.

To compare the efficiency and safety profile of conventional monopolar, bipolar plasmakinetic and holmium laser techniques for transurethral resection of bladder tumour. The prospective comparative study was conducted from July 2019 to May 2021 after approval from the ethicsreview committee of Kafrelsheikh University, Egypt, and comprised patients of either gender with primary non muscle invasive bladder cancer who qualified for transurethral resection of bladder tumour. The patients were stratified into low-risk group A, intermediate risk group B and high-risk group C in accordance with the guidelines of the European Association of Urology. Comprehensive cystoscopy and panendoscopy were done in all cases. Once panendoscopy was done, tumour resection was performed with monopolar resectoscope in group A, plasmakinetic resectoscope in group B and holmium laser in group C). Data was collected at preoperative, peroperative, postoperative and follow-up stages. Data was analysed using SPSS 21. Of the 84 patients, 67(79.76%) were males and 17(20.23%) were females. There were 27(32.14%) patients in group A; 21(77.8%) males and 6(22.2%) females withy mean age 60.63±11.76 years. Group B had 32(38%) patients; 26(81.2%) males and 6(18.8%) females with mean age 65.34±7.55 years. Group C had 25(29.76%) patients; 20(80%) males and 5(20%) females with mean age 59.48±12.6 years. The mean follow-up period was 12.97±2.70 months in group A, 12.81±2.75 monthsin group B and 13.48±3.3 monthsin group C. Visualised complete resection was done in 23(85.8%) group A patients, 29(90.6%) group B patients and 24(96%) group C patients(p=0.018). Visualised complete resection, tumour multiplicity, tumour size, catheter duration, and hospital stay were significant predictors (p<0.05). Survival analysis showed 26(96.3%), 30(93.75%) and 25(100%) cases in groups A, B and C, respectively. Bipolar plasmakinetic and holmium laser techniques were found to be more effective and safer than the conventional monopolar technique for transurethral resection of bladder tumour in patients with primary non-muscle invasive bladder cancer.

Role Of Prostate Ultrasonography To Predict The Efficacy Of Bipolar Prostatectomy In Benign Prostatic Hyperplasia.

To evaluate the role of prostatic ultrasonography in predicting the clinical outcomes of bipolar transurethral resection of the prostate. The prospective study was conducted at the Urology Department, Kafrelsheikh University Hospital, Cairo, Egypt from December 2018 to June 2019, and comprised male patients complaining of lower urinary tractsymptoms due to benign prostatic hyperplasia. The patients were subjected to pelvi-abdominal and transrectal ultrasonography and values were noted for the international prostate symptom score, uroflowmetry, post-void residual urine volume, ejaculatory domain, and the erectile function domain of the international index of erectile function. The safety of the procedure was assessed using the modified Clavien classification of complications. This was followed by cystourethroscopy under spinal anaesthesia, and then by bipolar resection of the prostate by a single experienced urologist. Operating time, length of hospitalisation, intraoperative and postoperative complications, catheterization time, and changes in haemoglobin levels were recorded. All evaluations were done at baseline and postoperatively at 1, 3 and 6 months. Data was analysed using SPSS 21. There were 109 male patients with mean age 65.53±6.27 years, mean body massindex 24.6±1.7kg/m2 . Mean total prostate volume at baseline was 86.32±43.61gm (range: 30-195m). There was a significant decrease postoperatively (p<0.001). This was associated with a concomitant improvement of international prostate symptoms score, uroflowmetry and post-void residual urine volume over six-month follow-up (p<0.001 ). Overall, 63(57.8%) subjects were sexually active, and there was no significant difference in the international index of erectile function score at baseline and postoperatively (p>0.05). Prostate ultrasonography can be used as a single investigating tool to evaluate the clinical outcomes after bipolar transurethral resection of the prostate.

Can the Sandwich Method Be an Alternative Treatment Choice for BPH Patients With Large Prostates?

ObjectiveTo compare the efficacy and safety of the sandwich method with GreenLight photoselective vaporization (GLPVP) and bipolar transurethral resection (B-TURP) with those of the enucleation method in patients with BPH and a prostate volume ≥ 80 g. MethodsPatients with BPH who underwent either the sandwich method with GLPVP and B-TURP or the enucleation method between 2014 and 2021 were included in the analysis. The primary outcome was the comparison of uroflowmetry results between the 2 groups. Safety analysis of the complication rates was also compared. ResultsThe cohort included 55 patients in the sandwich group and 41 patients in the enucleation group. In the efficacy analysis, both groups showed comparable uroflowmetry results, except for a higher postoperative average flow rate in the enucleation group. Regarding perioperative parameters, the sandwich method required a longer operating time, and the enucleation group had a higher incidence of manual Foley irrigation. Both groups demonstrated similar postoperative complications. ConclusionThe sandwich method exhibited comparable efficacy and safety to the enucleation method in patients with BPH with a prostate volume ≥ 80 g. Thus, for surgeons who are familiar with GLPVP and B-TURP, the sandwich method may be an alternative surgical approach for BPH patients with large prostates.
