Functional Outcome and Safety of Endoscopic Treatment Options for Benign Prostatic Obstruction (BPO) in Patients ≥ 75 Years of Age.

Background: The selection of suitable patients for the surgical treatment of benign prostatic obstruction (BPO) is a challenge in persons ≥75 years of age. Methods: After a systematic literature search of PubMed, 22 articles were included in this review. Clinical and functional parameters were evaluated statistically. Results: The mean age of the patients was ≥79 years. The mean duration of postoperative catheterization ranged between 2 (d) (ThuLEP, thulium laser enucleation of the prostate) and 4.4 days (TURP, transurethral resection of the prostate). Complication rates ranged between 6% (HoLAP, holmium laser ablation of the prostate) and 34% (PVP, photoselective vaporization of the prostate); the maximum rate of severe complications was 4% (TURP). The mean postoperative maximal urinary flow (Qmax) in mL/sec. ranged between 12.9 mL/sec. (HoLAP) and 19.8 mL/sec (Hol-TUIP, holmium laser transurethral incision of the prostate). The mean quality of life (QoL) score fell from 4.7 ± 0.9 to 1.8 ± 0.7 (HoLEP), from 4.1 ± 0.4 to 1.9 ± 0.8 (PVP), from 5.1 ± 0.2 to 2.1 ± 0.2 (TURP), and from 4 to 1 (ThuVEP, thulium laser vapoenucleation of the prostate). Pearson's correlation coefficient (r) revealed a positive linear correlation between age and inferior functional outcome (higher postoperative International Prostate Symptom Score (IPSS) [r = 0.4175]), higher overall complication rates (r = 0.5432), and blood transfusions (r = 0.4474) across all surgical techniques. Conclusions: This meta-analysis provides the summary estimates for perioperative and postoperative functional outcome and safety of endoscopic treatment options for BPO in patients ≥ 75 years of age. Of particular importance is that all surgical techniques significantly improve the postoperative quality of life of patients in this age group compared to their preoperative quality of life.

Day surgery in the treatment of benign prostatic obstruction with photoselective vaporisation of the prostate: A single‐institution experience

AbstractAimTo assess the feasibility, efficacy and safety of performing photoselective vaporisation of the prostate (PVP) as a day‐surgery procedure for patients with benign prostatic obstruction.Patients and MethodsA prospective single‐arm observational study was performed involving patients with benign prostatic obstruction (BPO) who received PVP between 2017 and 2021. Data were collected on demographics, prostate volume by transrectal ultrasonography, mean peak flow rate (Qmax), post‐void residual urine volume, International Prostate Symptom Score (IPSS) with quality‐of‐life (QoL) index, length of stay, success in weaning off catheter on the day of operation and complications.ResultsPVP was performed successfully in all 37 men between 2017 and 2021. Their mean age was 67 years. The mean prostate volume was 54 mL. The mean duration of operation was 80 min. The mean peak urinary flow rate improved from 9.14 to 16.8, 17.3 and 15.4 mL/s at post‐operative 1, 3 and 12 months, respectively (P = .001). The mean IPSS score improved from 19.5 to 8.94, 6.40 and 5.63 at post‐operative 1, 3 and 12 months, respectively (P < .001). The mean QoL index improved from 4.07 to 2.43, 2.25 and 1.81 at post‐operative 1, 3 and 12 months, respectively (P = .001). The mean duration of catheterisation after PVP was 5.81 h. Thirty‐three (89.2%) patients were discharged on the same day. Overall, the 30‐day complication rate was 27%. The most common complication was haematuria (6 patients, 16.2%). Five patients (13.5%) required readmission and inpatient care. There was one Clavien–Dindo grade III and IV complication (2.6%), respectively.ConclusionThis study demonstrated the feasibility of performing PVP as a day‐surgery procedure with good short‐ and medium‐term functional outcomes and safety profiles.

Evaluation of new treatments for benign prostatic obstruction: ICI‐RS 2023

AbstractAimsTo address how invasive therapies for benign prostatic obstruction (BPO) have been evaluated, what their effect is on BPO, if they can prevent progression to BPO and how new therapies need to be evaluated before implementation into clinical practice.MethodsThe think tank conducted a literature review and looked at the previous and current American Urological Association, European Association of Urology and the International Consultation on Urological Diseases guidelines to see what procedures have been used to treat BPO. They then assessed whether trials have been conducted before implementation of the procedures and whether they have been compared to a “gold” standard treatment. The use of urodynamics has also been addressed in the think tank in relation the clinical trials as well as terminology.ResultsGuidelines vary in the use of terminology when it comes to BPO with some continuing to use the term benign prostatic hyperplasia (BPH). There are several procedures for example, TUNA, which have become obsolete although continues to be mentioned in the guidelines until recently. Majority of procedures have been introduced without comparing to “gold” standard treatment and without any long‐term data. There continues to be many unknowns with regard to the success of some of the BPO procedures and why some of the adverse events develop.ConclusionThere needs to be more robust long‐term clinical trials conducted of new BPO therapies, with men who have both lower urinary tract symptoms and urinary retention, before introduction into clinical practice.

Comparative analysis of robot-assisted simple prostatectomy: the HUGO™ RAS system versus the DaVinci® Xi system.

Robot-Assisted Simple Prostatectomy (RASP) has emerged as a promising alternative in the treatment of benign prostatic obstruction (BPO). However, there is currently a lack of comparative studies evaluating different robotic platforms for performing RASP. Therefore, we aimed to compare perioperative and functional outcomes of RASP performed using the HUGO™ RAS System versus the DaVinci® Xi System. Forty consecutive cases of RASP performed between May 2021 and March 2023 with the HUGO™ RAS and the DaVinci® Xi at OLV Hospital (Aalst, Belgium) were included in this retrospective study. All surgeries were performed by three experienced surgeons using the same approach. Baseline characteristics, peri-operative and functional outcomes were collected and compared between the two groups. The population was equally divided between the two groups with 20 patients in each group. There were no significant differences in preoperative patient characteristics between the two groups, except for the presence of bladder stones prior to the surgery (p = 0.03). No significant differences in total operative time and console time between the two groups were reported (p = 0.3). No cases required conversion to open surgery or additional port placement. During one case performed with the HUGO™ RAS, a malfunctioning monopolar curved shear had to be replaced. However, there was no statistically significant differences in terms of technical robotic problems between the groups (p = 0.3). There was no significant difference between the two groups in perioperative and functional outcomes (all p ≥ 0.2). We did not observe any statistically significant difference in perioperative and functional outcomes in case of RASP performed with the HUGO™ RAS System and with the DaVinci® Xi System. These findings provide compelling support for considering the HUGO™ RAS as a promising tool for robot-assisted procedures, thereby expanding the utilization of robotics for benign conditions.

Transperineal laser ablation as treatment for benign prostatic obstruction: Safety, feasibility and functional outcomes-A pilot study.

Standard surgical treatment for lower urinary tract symptoms (LUTS) due to benign prostatic obstruction (BPO) requires anaesthesia and hospitalization. Transperineal laser ablation (TPLA) is a novel minimally invasive treatment for BPO, which has been performed using local anaesthetics and conscious sedation. The aim of this study is to assess safety, feasibility and functional outcomes of TPLA for the treatment of LUTS in men fit also for standard surgery. This prospective, multicentre, interventional pilot study included 20 patients. Eligible patients were men ≥40 years of age, with urodynamically proven bladder outlet obstruction, a peak urinary flow of 5-15 mL/s and a prostate volume of 30-120 cc. All subjects underwent Soractelite™ TPLA using the Echolaser® X4 system. Two to four fibres were placed in the prostate, whereafter laser light induced coagulative necrosis. Twelve months of follow-up included uroflowmetry, an ultrasound of the prostate and PROMs (IPSS and IIEF). Twenty patients were treated with TPLA using local anaesthetics and optional sedation. Sixteen patients were treated in an outpatient setting, using only local anaesthetics in 12 of them; four were treated in the operating room, whereof two under general anaesthesia. No device related adverse events occurred, nor did any grade ≥3 adverse events during follow-up. Post-TPLA, 10 men continued spontaneous voiding, and 10 men developed a urinary retention treated by a temporary indwelling catheter for 15.2 ± 3.5 days. At 12 months, Qmax improved from 9.7 ± 3.5 to 14.9 ± 6.0 (p = 0.015), IPSS improved from 21.3 ± 5.2 to 10.9 ± 5.5 (p < 0.0001), QoL improved from 4.9 ± 0.9 to 1.9 ± 1.1 (p < 0.0001), IIEF-15 total score remained stable and 11/13 patients (85%) preserved antegrade ejaculation. TPLA is a safe and feasible treatment for men with LUTS due to BPO. TPLA can be performed in an outpatient setting under only local anaesthetics. Functional and quality of life outcomes improved significantly at 12 months, and erectile function remained stable.

Greenlight laser (XPS-180watt) prostatectomy for treatment of benign prostate obstruction, Pursuit of durability

ABSTRACT Objectives To report 5-year outcomes, need and predictors of retreatment post greenlight laser photoselective vaporization (GL.PVP) and vapo-enucleation (GL.PVEP), as long-term data on safety and efficacy of GL.PVP and GL.PVEP and on the prostate using XPSTM system are still pending. Patients and methods Primary outcome was the need for retreatment (medical treatment and reintervention) for recurrent BOO. Time-to-event (retreatment) analysis, perioperative events, change in the urinary outcome measures at different follow-up visits, early and late complications and PSA kinetics were reported. Results Between September 2014 and April 2017, 248 patients underwent GL/XPS procedures. GL.PVP and GL.PVEP were carried out for 157 (63.3%) and 91 (36.7%) patients with mean prostate sizes of 60 ± 18 and 100 ± 22 cc, respectively. After a mean duration of 62 ± 9-month follow-up, overall retreatment rate (medical and interventional) was 23% (57 patients). It was comparable between both GL.PVP and GL.PVEP cases: 38 (24.2%) and 19 (20.9%) patients, P = 0.5, respectively. Significantly more surgical reintervention rate was reported after GL.PVP compared to GL.PVEP (P = 0.03). In retreatment group, more intraoperative bleeding (P = 0.02), early postoperative hematuria (P = 0.03), higher median preoperative PSA (P = 0.02) and less postoperative one-year percent PSA reduction (P = 0.02) were detected. Lower postoperative one-year percent PSA reduction independently predicts retreatment with a cut-off point of 64.2% (58.2% sensitivity, 73.4% specificity, AUC 0.647, 95% CI 0.52–0.76). Median (range in months) time to event was 20 (1–60) for all cases and 13.5 (1–42) and 30 (18–60), P = 0.7, for GL.PVP and GL.PVEP groups, respectively. Conclusion Greenlight laser XPS is an effective, durable and versatile tool in treating benign prostatic obstruction. Durability of the outcome is predictable with more postoperative PSA reduction.

Aquablation Treatment for Benign Prostatic Obstruction

Aquablation Treatment for Benign Prostatic Obstruction Abstract: The surgical BPH treatment is one of the most common urological procedures. With our reference methods: transurethral resection of the prostate (TUR-P), open surgical adenomenucleation over a transabdominal access, and also modern laser procedures. Various effective surgical options are available. However, the quality of the surgical outcome is highly dependent on the surgeons' experience. At the same time, all of the above-mentioned reference methods are associated with a high rate of sexual dysfunction, especially postoperative anejaculation, a symptom complex which is relevant for men, regardless of age [1]. Robotic Aquablation® was developed with the goal to reduce the dependency of the surgical outcome on the expertise of the surgeon, but at the same time achieving a comparable outcome and reduced morbidity. After the "first in human treatment" by Peter Gilling in 2013, the Aquabeam® robot has been used in its current form in clinical studies since 2015 (Water, Water II and Open Water Study) and finally was introduced in clinical routine in August 2017 by Thorsten Bach in Hamburg. The safety and effectiveness of Aquablation® therapy has been proven in various studies and in everyday clinical practice.

No study investigated the actual rate of preservation of the ejaculatory function after TPLA, in comparison to the reference standard trans-urethral resection of prostate (TURP). We aimed to evaluate the reliability of TPLA in preserving the ejaculation compared to TURP. METHODS: In this single-center, prospective, randomized, open-label study, consecutive patients with indication to surgical treatment for BPO were enrolled between January 2020 and September 2021 (NCT04781049). Randomization defined two treatment arms: Group A: patients assigned to TPLA (experimental); Group B: patients assigned to TURP (standard). Primary endpoints included comparison of visual analogue scale (VAS), change in ejaculatory function (by EJ-MSHQ), and changes in sexual function (by IIEF-5) at 1 month after surgery. Secondary endpoints included ΔIPSS and ΔQoL, and Qmax improvement at 6 months. RESULTS: Fifty-one patients (26 TPLA versus 25 TURP) were analyzed. No differences were found in the perception of pain assessed by VAS. No differences in IIEF-5 score were found between groups. Distribution of ejaculatory function assessed by the EJ-MSHQ remained unmodified after TPLA (p=0.2) while a median 31% decrease in EJ-MSHQ score (IQR -67;-14%) was observed after TURP (p=0.01). Retrograde ejaculation was reported in one patient within the TPLA group (18 patients s/p TURP). A statistically significant difference between the treatment groups was found in terms of postoperative Qmax (15.2 (IQR 13.5–18.3) versus 26.0 (IQR 22.0–48.0) ml/s, TPLA versus TURP, p<0.001). Qmax was statistically significantly improved with respect to baseline after TPLA (%ΔQmax+42 (+24; +76), p<0.001). Both treatments significantly improved IPSS and QoL with respect to baseline, with TURP impacting more significantly (%ΔIPSS -35.9 (IQR -54.5; -1.3) versus -66.7 (-82.8; -46.7) and %ΔQoL -33.3 (-50; -8) versus -60.0 (IQR -80; -33), TPLA versus TURP, all p-values <0.03). CONCLUSIONS: TPLA allowed for maintaining ejaculation in 96% of the cases, confirming to be valid option in patients seeking for pairing the relief from BPO to the high probability of preserving ejaculatory function.

Prostatic Artery Embolization for The Treatment of Benign Prostatic Obstruction - A Retrospective Review of The Novel Experience Of 2 Tertiary Urology Centers

Background: Benign Prostatic Hyperplasia (BPH) is common in aging men with worldwide prevalence at 20-62%, while Malaysian prevalence was 39.3% (2001) and increased at 8% per decade. In surgical treatment of BPH, Trans-Urethral Resection of Prostate (TURP) remains the gold standard. Other surgical options would mostly also require general anesthesia (GA). Therefore, more Local-Anaesthesia (LA) based options should be made available for patients who are not fit or unwilling to be under GA. Those currently available LA-based procedure has shown promising results including prostatic stents and trans-urethral lifts, but have drawbacks due to being expensive, not widely available, less suitable in median lobe enlargement or may cause complications including migration, overgrowth of prostatic tissue or foreign-body related complications which may require GA for their treatment. Prostatic Artery Embolization (PAE), initially an LA-based emergency treatment option for persistent life-threatening hematuria from a bleeding BPH, now has been proven to be a safe elective treatment. In Malaysia this novel technique was first reported in 2017 for treatment of post TURP intractable hematuria. Methods and Material: We retrospectively evaluated all 13 catheter-dependent BPH patients in two tertiary urology centres treated with PAE from April 2019 until December 2021 to assess post-treatment efficacy. Results: One patient failed removal of catheter within 3 months post-procedure but 12 out of 13 patients safely got their catheter removed within 1-3 months and resulted in significant IPSS improvement. Conclusion: PAE is a safe and effective treatment option for BPH patients of the Malaysian population but needs prospective evaluation.

Comparison of postoperative functional results in holmium laser enucleation of the prostate, green laser photovaporization of the prostate and transurethral resection of the prostate in the treatment of obstructive prostatic hyperplasia

Objective: To compare the functional results in patients undergoing transurethral resection of the prostate (TURP), photovaporization of the prostate with GreenLight ® laser (FTV) and prostate enucleation with Holmium laser (HOLEP), for the treatment of benign prostatic obstruction at the Central Military Hospital. Material and methods: The international index of prostate symptomatology questionnaire (IPSS), Uroflowmetry (Qmax), pre and post void ultrasonography (PVR) were applied to patients undergoing TURP, VTF and HOLEP pre and postoperatory from January 2018 to March 2019. Shapiro-Wilks tests were analyzed for quantitative variables; parametric behavioral data were analyzed with ANOVA tests, and non-parametric data were analyzed with Mann-Whitney and Kruskal-Wallis U tests. GraphPad PRISM v7.0 statistical package was used. Results: 46 patients underwent to TURP, 62 to HOLEP and 17 to VFT were evaluated, removing those who did not achieve complete postoperative follow-up; describing the demographic characteristics, the most frequent comorbidities and the parameters evaluated preoperatively. At follow-up, HOLEP was slightly better than FTV or TURP; without finding statistical significance between the groups, observing an important improvement in the reference values of IPSS, Qmax and PVR after surgery in all populations. Conclusions: No superiority of any technique was proven in short-term postoperative functional results, so we propose to perform long-term studies, considering adding trans and postoperative parameters in order to demonstrate superiority of these techniques.

The Efficacy and Safety of Laser and Electrosurgical Transurethral Procedures for the Treatment of BPO in High-Risk Patients: A Systematic Review.

ObjectiveTo compare efficacy and safety outcomes of GreenLight, Holmium and Thulium laser techniques with standard monopolar and bipolar transurethral resection of the prostate (TURP) in high-risk patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO).MethodsWe conducted a systematic literature review of studies in patients undergoing BPO surgeries who may be considered high-risk for standard TURP, with higher risk defined as follows: large prostates (≥80 mL) and/or taking antithrombotic agents and/or urinary retention and/or age >80 years and/or significant comorbidity. Outcomes summarised included bleeding complications, re-intervention rates, hospital length of stay, and standard measures of disease and symptom severity for all available timepoints.ResultsA total of 276 studies of 32,722 patients reported relevant data. Studies were heterogeneous in methodology, population and outcomes reported. IPSS reduction, Qmax improvement and PVR were similar across all interventions. Mean values at baseline and after 12 months across interventions were 13.2−29 falling to 2.3−10.8 for IPSS, 0−19 mL/s increasing to 7.5−34.1 mL/s for Qmax and 41.4−954 mL falling to 5.1−138.3 mL for PVR. Laser treatments show some advantages compared with monopolar and bipolar TURP for some adverse events and safety parameters such as bleeding complications. Duration of hospital stay, reinterventions and recatheterisations were lower with GreenLight, HoLEP, Thulium lasers, and bipolar enucleation than TURP.ConclusionsLaser therapies are effective and well-tolerated treatment options in high-risk patients with BPO compared with monopolar or bipolar TURP. The advantageous safety profile of laser treatments means that patients with a higher bleeding risk should be offered laser surgery preferentially to mTURP or bTURP.

Do men with bladder stones benefit from treatment of benign prostatic obstruction?

To identify whether men aged ≥40 years with bladder stones (BS) benefit from treatment of benign prostatic obstruction (BPO). A regional, retrospective study of patients undergoing BS surgery between January 2011 and December 2018 was performed using a prospectively collected database. The primary outcome was BS recurrence after successful removal. Kruskal-Wallis and chi-squared statistical tests were used. A total of 174 patients underwent BS removal and 71 (40.8%) were excluded due to BS formation secondary to causes other than BPO. Hence, 103 men aged ≥40 years had BS successfully removed, of which 40% had a history of upper tract urolithiasis. These men were divided into three groups: those undergoing contemporaneous medical, surgical, or no BPO treatment. Age, diabetes, previous urolithiasis and previous BPO surgery were well matched between the BPO treatment groups. In all, 18 of these men (17%) had BS recurrence after 46 months follow-up. Recurrences were significantly lower following BPO surgery; one of 34 (3%) men versus five of 28 (18%) with no BPO treatment (P = 0.048) and 12 of 41 (29%) with medical BPO treatment (P = 0.003). Recurrences after medical and no BPO treatment were similar (P = 0.280). In all, 34 men (33%) had BPO complications that were similar between groups (P = 0.378). This is the largest reported cohort of men, with the longest follow-up after BS removal. Most men aged ≥40 years with BS benefit from BPO surgery. However, the study findings also support a multifactorial aetiology for BS, which questions the dogma that BS are an 'absolute indication' for BPO surgery, as is stated in the Non-neurogenic Male Lower Urinary Tract Symptoms European Association of Urology Guideline. Assessment and management of all causative factors is likely to enable selection of which men will benefit from BPO surgery and to reduce BS recurrence rates.

Endoscopic Enucleation of the Prostate Is Better than Robot-assisted Simple Prostatectomy

In 2022, endoscopic enucleation of the prostate (EEP) is the treatment of choice for benign prostatic obstruction (BPO) for glands >80 ml and is a valid alternative for patients with bleeding disorders. Unlike robot-assisted radical prostatectomy, EEP has no additional access-related trauma and can be performed using the same instruments as for bipolar enucleoresection. With favorable costs, EEP can serve as a global solution for BPO treatment.

Influence of Prostate Artery Embolization on Different Qualities of Lower Urinary Tract Symptoms Due to Benign Prostatic Obstruction

BackgroundProstate artery embolization (PAE) is an increasingly used minimally invasive treatment for lower urinary tract symptoms secondary to benign prostatic obstruction (BPO) ObjectiveTo analyze the impact of PAE on voiding and storage symptoms. Design, setting, and participantsBetween July 2014 and May 2019, 351 consecutive men with BPO who underwent PAE were included in a single-center study. InterventionPAE is an interventional radiological procedure embolizing the prostatic arteries with microspheres. Outcome measurements and statistical analysisThe primary endpoint represented assessment of the International Prostatic Symptom Score (IPSS) at baseline and at 1, 3, 6, 12, and 24 mo after PAE. Secondary endpoints comprised assessment of IPSS quality of life (QoL), International Index of Erectile Function, peak urinary flow rate, postvoid residual volume, prostate volume, and prostate-specific antigen at the same time points. Data were analyzed using standard statistical methods, generalized estimating equations (symptom improvement over time as odds ratios), and McNemar-Bowker test (degree of improvement compared between symptoms). Results and limitationsClinical success rates for PAE were 68%, 73%, and 66% at 1, 12, and 24 mo, respectively. The median IPSS improved significantly from 22 to 10 points after 2 yr (p < 0.001). Storage (–50%) and voiding (–58%) symptoms improved similarly (each p < 0.001), with nocturia decreasing least frequently but significantly (p < 0.001). After 1 and 2 yr, 35% (95% confidence interval [CI] 29–41%) and 30% (95% CI 21–40%) of patients reported alleviated storage, and 39% (95% CI 33–45%) and 38% (95% CI 29–49%) reported alleviated voiding symptoms, respectively. QoL improved from 5 to 2 points (p < 0.001). The main limitation is the number of patients lost during follow-up. ConclusionsPAE significantly improved voiding and storage symptoms to a similar extent. This study may aid in counseling patients about this minimally invasive BPO treatment. Patient summaryProstate artery embolization (PAE) is a minimally invasive treatment option for patients with voiding and storage symptoms from benign prostate enlargement. Our analysis shows that PAE improves relevant lower urinary tract symptoms.

Extraperitoneal laparoscopic simple prostatectomy with urethra preservation using urethral initiation as the entry point: a practical approach for the treatment of benign prostatic obstruction.

The present study introduces a modified surgical procedure, extraperitoneal laparoscopic simple prostatectomy (LSP) with urethra preservation using urethral initiation as the entry point, and evaluates its feasibility, safety, and efficacy in the treatment of benign prostatic obstruction (BPO). A total of 50 patients with BPO underwent modified LSP from January 2018 to December 2020. The main surgical procedures performed were as follows: transversely incision of prostate surgical capsule at the urethral initiation; creating of the subcapsular plane and the space between urethra and adenoma; removal of lobes with preservation of urethra followed by suturing of capsule. Preoperative, perioperative, follow-up parameters, and complications were recorded and analyzed. Operative time was (106.34 ± 28.00) min and intraoperative blood loss was (98.80 ± 130.58) ml. Continuous bladder irrigation (CBI) was not performed routinely, catheterization duration was (5.26 ± 2.99) days, and postoperative hospital stay was (5.42 ± 1.62) days. Significant improvements were observed in functional outcomes, whereas no retrograde ejaculation, urinary incontinence, and urethral stricture occurred. Urethral rupture was not significantly influenced by operative time, intraoperative blood loss, and prostate volume. However, it prolonged CBI duration, drainage tube retention time, catheterization duration, and postoperative hospital stay. Operative time decreased with an increase in the number of cases, and the surgeon achieved proficiency level after handling 21-25 cases. Extraperitoneal LSP with urethra preservation using urethral initiation as the entry point is a feasible, repeatable, safe, and effective surgical procedure, which is suitable for treating BPO.

Outcomes of bipolar TURP compared to monopolar TURP: A comprehensive literature review.

Transurethral resection of the prostate (TURP) is the commonest surgical procedure for the treatment of benign prostatic obstruction (BPO). Bipolar-TURP (BTURP) is being increasingly used as compared to the long-established Monopolar TURP (MTURP). In this systematic review, we compared the outcomes of BTURP vs MTURP. A systematic review was conducted using PubMed, EMBASE, Scopus, Google Scholar, and the Cochrane library using relevant search terms from inception of databases till June 2020. Using PRISMA methodology, 18 randomized control trials were reviewed comparing MTURP vs BTURP with a total of 8,393 patients. A significant drop in serum sodium was seen in four studies in MTURP vs BTURP and while there was zero incidence of TUR syndrome in BTURP group, there were 1-16 episodes of TUR syndrome across studies in the MTURP group. A significant fall in hematocrit was seen in three of nine studies with MTURP and one with a significant difference in blood transfusion rates. There were no significant differences in the incidence of clot retention across the studies with 1-5 cases in BTURP group vs 2-12 cases in MTURP group. There were no significant differences related to the duration of catheterization, operative time, resection volume, length of stay, quality of life, postoperative urethral stricture, and sexual function. Although both BTURP and MTURP improve urinary symptoms, BTURP is associated with less risk of hyponatremia, TUR syndrome, and blood loss compared to MTURP. There seems to be no significant difference in length of stay, urethral stricture, quality of life, and operative duration.

Learning curve in aquablation: an international multicenter study.

To describe and analyze the learning curve (LC) of aquablation for the treatment of benign prostatic obstruction and determine the number of cases needed to achieve acceptable surgical safety, efficiency, and efficacy. A retrospective analysis of prospectively maintained aquablation databases from France, Lebanon, and Spain was conducted. The combined LC of three surgeons was defined by trifecta and pentafecta outcomes. Trifecta reflected efficiency and safety: operative time < 60min, hemoglobin reduction ≤ 2mg/dL, and no 90day Clavien-Dindo grade ≥ 2 complications. Pentafecta reflected effectiveness: percent reduction in International Prostate Symptom Score (IPSS) and ejaculation preservation. The combined LC was plotted using a moving average with polynomial fitting. The cohort included 175 consecutive patients. Median (IQR) prostate volume was 70 (50-91) cc, and baseline IPSS was 23 (18-27). The achievement of trifecta exceeded 50% after 4 cases, and 70% after 50 cases. Pentafecta achievement exceeded 50% after 38 cases. Logistic regression showed significant improvement in hemoglobin reduction and ejaculation preservation. Grade ≥ 2 complication was not affected by experience, and neither was 3month %IPSS reduction as 94% of patients showed ≥ 50% symptoms' improvement. Aquablation is associated with a quick learning curve for the defined trifecta and pentafecta outcomes. It provided effective LUTS relief and low complication rates independent of surgeon experience. Hemoglobin drop and ejaculatory function preservation were the two factors influenced by the surgeons' LC. Training to reduce operative time, standardization of hemostasis techniques, and early assistance to improve veru-protection zone planning are keys to quicker learning.

Changes in transient receptor potential vanilloid 1 and transient receptor potential vanilloid 4 in patients with lower urinary tract dysfunction.

PurposeWe investigated the association between transient receptor potential vanilloid (TRPV) expression in human urothelium tissue and lower urinary tract dysfunction (LUTD).Materials and MethodsWe prospectively enrolled men who planned to undergo surgical treatment for benign prostatic obstruction to analyze TRPV1 and TRPV4 expression in the urothelium using enzyme-linked immunosorbent assay and immunofluorescence staining. Patients were divided into two groups based on urodynamics: the detrusor underactivity (DU) group and the non-DU group. Levels of TRPV1 and TRPV4 were compared between the two groups. We also divided patients into two groups according to degree of subjective urinary urgency symptoms using a 5-point urinary sensation scale and compared the differences in TRPV1 and TRPV4 levels between the two groups. The correlations between urodynamic parameters with TRPV1 or TRPV 4 in all patients were also analyzed.ResultsThe levels of TRPV1 and TRPV 4 were not significantly different between the DU group (n=10) and the non-DU group (n=11). When we divided the patients according to degree of subjective urgency, the level of TRPV1 was not significantly different between the urgency group (n=10) and the non-urgency group (n =11), but the level of TRPV4 was significantly increased in the urgency group (p=0.029). There was no significant correlation between the level of TRPV1 or TRPV4 and urodynamic parameters in any patients.ConclusionsTRPV4 could be a useful diagnostic biomarker for patients with LUTD.

Surgical treatment options for benign prostatic obstruction: beyond prostate volume.

Many surgical treatment options are available for patients who present with benign prostatic obstruction (BPO). This article reviews the current treatment options available and distinguishes them based on five clinical considerations: antithrombotic therapy, sexual function preservation, ambulatory procedures, anesthesia-related risks and duration of catheterization. A comprehensive review of the literature was performed on 10 BPO procedures. Laser enucleation of the prostate (LEP), bipolar plasma transurethral vaporization of the prostate and photoselective vaporization (PVP) of the prostate reduces the risk of bleeding, which is recommended for anticoagulated men. Ejaculatory function is more likely to be preserved following transurethral incision of the prostate, Rezūm, Aquablation, UroLift and iTind. Same-day discharge is possible for LEP, PVP and prostatic arterial embolization (PAE). For patients with high anesthesia-related risks, procedures compatible with local anesthesia (UroLift, Rezūm, iTind and PAE) should be favored. Catheterization duration is shorter with UroLift, PVP and LEP. BPO treatment options are growing rapidly. The optimal procedure for a given patient is based on factors such as associated risks, recovery and expected outcomes. Besides prostate volume, the clinical considerations in the present article can help elucidate the best surgical BPO treatment option for each patient based on their values, preferences, and risk tolerance.
