Bipolar transurethral enucleation and resection of the prostate: Whether it is ready to supersede TURP?

ABSTRACT: Objective:According to the EAU Guidelines, transurethral resection of the prostate (TURP) has so far still been considered as the gold standard for surgical treatment for patients with obstructing clinical benign prostate hyperplasia (BPH). However, its relatively high rate of complications and postoperative recurrence necessitates further modification and innovation on the surgery technique. We reported the patient outcomes with our technique. Methods:We retrospectively analyzed 52 patients with obstructing clinical BPH who underwent bipolar transurethral enucleation and resection of the prostate (B-TUERP) between March 2015 and September 2015. Pre- and perioperative parameters were obtained from medical charts. Postoperative follow-ups were administrated at 1, 3, 6, 12 and 24 month(s) after surgery, respectively. Results:All the operations were performed successfully with a mean operative time of 43.1 min and an average tissue removal rate of 74.7%. Qmax was significantly improved immediately after surgery, followed by a continuous improvement throughout the follow-ups. Following a steep decrease in mean prostate specific antigen (PSA) and post void residual (PVR) observed within the first half year after surgery, the serum PSA was then maintained at a constant level of 0.61 ng/mL. Temporary urinary retention was found in four cases (7.7%). Stress urinary incontinence occurred in five patients (9.6%), with the condition resolved in 1-2 weeks without extra treatment. Urethral strictures and bladder neck contractures, as the most commonly observed long-term complications, developed in four patients (7.7%). No recurrence was found during 2 years of follow-ups. An improvement in International Index of Erectile Function (IIEF-5) scores was witnessed in 17 patients preoperatively with normal sexual function during the first 6 months after surgery, and sustained throughout the 24-month period. Conclusions:Enucleation reflects an improvement on surgical technique in many ways with a need for surgical equipment that can be broadly accessible in clinical practice. Currently, bipolar resection is a commonly employed procedure in clinical settings, and its similarity shared with bipolar enucleation technique warrants a quick learning of B-TUERP by urologists. Based on these findings, we believe that the substitution of TURP by TUERP as the gold standard for prostate endoscopic procedure can be expected in the future.

Project description:BackgroundBipolar Transurethral Enucleation of the Prostate (B-TUEP) is recommended as a first-choice treatment for benign prostatic obstruction in prostates >80 ml. Differently, B-TUEP is only considered as an alternative option after TURP for smaller prostates (30-80 ml). The aim of our study is to assess the relation between prostate size and surgical outcomes after B-TUEP.MethodsWe performed a retrospective analysis of data collected from 172 patients submitted to B-TUEP. Patients were segregated according to tertiles of prostate volume (PV) (≤60 ml, 61-110 ml, >110 ml). For each group we evaluated enucleation efficacy (enucleated weight/enucleation time), complication rates, urinary and sexual function parameters. Functional and sexual parameters were compared between groups at baseline, 1 and 3 months follow up. Descriptive statistics and linear and logistic regression models tested the association between PV and postoperative complications/outcomes.ResultsOperative time and weight of enucleated adenomas increased along with prostate volumes (all p≤0.01). Enucleation efficacy was higher in men with PV >110 ml compared to other groups (p≤0.001). Length of hospital stay, catheterization time and rates of postoperative complications, such as transfusion and clot evacuation rates and bladder neck/urethral strictures, were comparable between groups. Urinary symptoms improved at 1-and 3-months in each group as compared to baseline evaluation (all p<0.01) but they did not differ according to PV. In each group maximum urinary flow and post-void residual volume significantly improved at 3 months compared to baseline (all p≤0.01), without differences according to PV. Sexual symptoms were similar between groups at each follow up assessment. At multivariable linear and logistic regression analysis, prostate volume was not associated with postoperative functional outcomes and complications. Conversely, patient's comorbid status and antiplatelet/anticoagulation use were independently associated with postoperative complications.ConclusionAccording to our findings, B-TUEP should be considered a "size independent procedure" as it can provide symptom relief in men with prostates of all sizes with the same efficacy and safety profile.

Project description:ObjectiveTo compare prostatic artery embolisation (PAE) with transurethral resection of the prostate (TURP) in the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia in terms of patient reported and functional outcomes.DesignRandomised, open label, non-inferiority trial.SettingUrology and radiology departments of a Swiss tertiary care centre.Participants103 patients aged ≥40 years with refractory lower urinary tract symptoms secondary to benign prostatic hyperplasia were randomised between 11 February 2014 and 24 May 2017; 48 and 51 patients reached the primary endpoint 12 weeks after PAE and TURP, respectively.InterventionsPAE performed with 250-400 μm microspheres under local anaesthesia versus monopolar TURP performed under spinal or general anaesthesia.Main outcomes and measuresPrimary outcome was change in international prostate symptoms score (IPSS) from baseline to 12 weeks after surgery; a difference of less than 3 points between treatments was defined as non-inferiority for PAE and tested with a one sided t test. Secondary outcomes included further questionnaires, functional measures, magnetic resonance imaging findings, and adverse events; changes from baseline to 12 weeks were compared between treatments with two sided tests for superiority.ResultsMean reduction in IPSS from baseline to 12 weeks was -9.23 points after PAE and -10.77 points after TURP. Although the difference was less than 3 points (1.54 points in favour of TURP (95% confidence interval -1.45 to 4.52)), non-inferiority of PAE could not be shown (P=0.17). None of the patient reported secondary outcomes differed significantly between treatments when tested for superiority; IPSS also did not differ significantly (P=0.31). At 12 weeks, PAE was less effective than TURP regarding changes in maximum rate of urinary flow (5.19 v 15.34 mL/s; difference 10.15 (95% confidence interval -14.67 to -5.63); P<0.001), postvoid residual urine (-86.36 v -199.98 mL; 113.62 (39.25 to 187.98); P=0.003), prostate volume (-12.17 v -30.27 mL; 18.11 (10.11 to 26.10); P<0.001), and desobstructive effectiveness according to pressure flow studies (56% v 93% shift towards less obstructive category; P=0.003). Fewer adverse events occurred after PAE than after TURP (36 v 70 events; P=0.003).ConclusionsThe improvement in lower urinary tract symptoms secondary to benign prostatic hyperplasia seen 12 weeks after PAE is close to that after TURP. PAE is associated with fewer complications than TURP but has disadvantages regarding functional outcomes, which should be considered when selecting patients. Further comparative study findings, including longer follow-up, should be evaluated before PAE can be considered as a routine treatment.Trial registrationClinicaltrials.gov NCT02054013.

Project description:BACKGROUND: Holmium laser enucleation (HoLEP) in surgical treatment of benign prostate hyperplasia (BPH) potentially offers advantages over transurethral resection of the prostate (TURP). METHODS: Published randomized controlled trials (RCTs) were identified from PubMed, EMBASE, Science Citation Index, and the Cochrane Library up to October 10, 2013 (updated on February 5, 2014). After methodological quality assessment and data extraction, meta-analysis was performed using STATA 12.0 and Trial Sequential Analysis (TSA) 0.9 software. RESULTS: Fifteen studies including 8 RCTs involving 855 patients met the criteria. The results of meta-analysis showed that: a) efficacy indicators: there was no significant difference in quality of life between the two groups (P>0.05), but compared with the TURP group, Qmax was better at 3 months and 12 months, PVR was less at 6, 12 months, and IPSS was lower at 12 months in the HoLEP, b) safety indicators: compared with the TURP, HoLEP had less blood transfusion (RR 0.17, 95% CI 0.06 to 0.47), but there was no significant difference in early and late postoperative complications (P>0.05), and c) perioperative indicators: HoLEP was associated with longer operation time (WMD 14.19 min, 95% CI 6.30 to 22.08 min), shorter catheterization time (WMD -19.97 h, 95% CI -24.24 to -15.70 h) and hospital stay (WMD -25.25 h, 95% CI -29.81 to -20.68 h). CONCLUSIONS: In conventional meta-analyses, there is no clinically relevant difference in early and late postoperative complications between the two techniques, but HoLEP is preferable due to advantage in the curative effect, less blood transfusion rate, shorter catheterization duration time and hospital stay. However, trial sequential analysis does not allow us to draw any solid conclusion in overall clinical benefit comparison between the two approaches. Further large, well-designed, multicentre/international RCTs with long-term data and the comparison between the two approaches remain open.

Project description:BackgroundTransurethral resection of the prostate (TURP) was considered the golden standard to treat benign prostatic hyperplasia (BPH) for decades. However, TURP was associated with low efficiency to alleviate the lower urinary tract symptoms (LUTS) and a significantly higher risk of bladder neck contracture (BNC) for patients with small-volume BPH. Our study aims to compare the therapeutic effect of a transurethral split of the prostate (TUSP) with TURP for patients with small-volume BPH (<30 mL).MethodsIn this study, 101 small-volume BPH patients were randomly divided into two groups (TUSP and TURP group). The patient's baseline characteristics and perioperative outcomes were recorded. The follow-up was done at six months, one year and two years after surgical treatment.ResultsNo significant differences were observed between the two groups for the baseline characteristics, including age, prostate volume, prostate-specific antigen (PSA) level, concurrent disease, post-void residual (PVR), maximum urinary flow rate (Qmax), international prostate symptoms score (IPSS), and quality of life (QoL) score. The operative time and hemoglobin decrease were significantly lower in the TUSP group compared to the TURP group. However, no significant differences were observed between both groups for catheterization time, postoperative hospital stay, and incidence of transurethral resection syndrome (TURS). However, of the late complications, the incidence of BNC in the TUSP group was significantly lower than the TURP group. No significant differences were found between both groups for other complications, including postoperative bleeding, micturition urgency, micturition frequency, micturition pain, urinary tract infection, recatheterization, transient incontinence, and continuous incontinence. Follow-up results showed that the IPSS of the TUSP group was significantly lower than the TURP group, while the Qmax of the TUSP group was significantly higher than the TURP group.ConclusionsThis study shows that TUSP may be an efficient and safe treatment for small-volume BPH (<30 mL) with a lower incidence of postoperative BNC and better longtime clinical outcomes than TURP. It suggested that TUSP could be an ideal treatment choice for small-volume BPH.
