Australian surgical revision rate for benign prostatic obstruction.

OBJECTIVE: To evaluate the rate of revision surgery following commonly performed procedures for benign prostatic hyperplasia (BPH) is hyperplasia of both glandular and stromal components of prostate especially in periurethral transitional gland, using real-world data from Medicare Australia. METHODS: Prospection is a Healthcare Data Analytics firm that has negotiated access with the Medicare Benefits Schedule (MBS) to provide longitudinal data on the use of specific procedural item codes. We identified patients over the age of 40 years who had undergone primary transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP) or photoselective vaporization of the prostate (PVP) between 2005 and 2010 using MBS item numbers 37203, 37207 and 36854, respectively. Using longitudinal MBS data, primary outcomes included need for revision surgery at 5-years follow-up (2015). The release of these data was approved by Medicare Australia upon application. Data analysis was conducted using chi-squared tests and statistical significance was defined at P < 0.05. RESULTS: The distribution of primary surgical procedures performed between 2005 and 2010 was: TURP 5579 (90%), TUIP 345 (6%) and PVP 258 (4%). TURP was also the most prevalent procedure for treatment of lower urinary tract symptoms in men with BPH requiring revision surgery (75%). At 5-year follow-up the rate of revision surgery for TURP (573/5579), TUIP (47/345) and PVP (30/258) was 10.3%, 13.6% and 11.6%, respectively. The difference was not statistically significant (P = 0.12). There was no significant change (P = 0.59) observed over the years in number of men requiring revision surgery. CONCLUSION: This study indicates that TURP and PVP have a similar durability after 5 years of follow-up.

The Effects of Multimodal Prehabilitation Interventions in Men Affected by Prostate Cancer on Physical, Clinical and Patient Reported Outcome Measures: A Systematic Review.

OBJECTIVES: To synthesize existing evidence on the effects of multimodal prehabilitation interventions in men affected by prostate cancer on physical, clinical, and patient-reported outcome measures. DATA SOURCES: A systematic review was conducted according to the PRISMA 2020 Statement Guidelines. Electronic databases (ie, Medline, Embase, CINAHL and Cochrane CENTRAL, and clinicaltrials.gov) were searched using key search terms. Articles were assessed according to prespecified eligibility criteria. Data extraction and quality appraisal was conducted. The findings were integrated in a narrative synthesis. CONCLUSION: Of the 5863 publications screened, 118 articles were assessed in full text and 17 studies met the prescreening eligibility criteria. There were a range of study designs that included randomized controlled clinical trials (n = 11), quasi experimental (n = 4), cohort (n = 1), and case series (n = 1), covering a total of 1739 participants. The prehabilitation interventions included physical activity, peer support, pelvic floor muscle training, diet, nurse-led prehabilitation, psychological, and prehabilitation administration of phosphodiesterase-5 inhibitors. IMPLICATIONS FOR NURSING PRACTICE: Significant heterogeneity existed in the prehabilitation intervention programs for men affected by prostate cancer in terms of the composition, duration, method of administration, and the outcomes measured to quantify their impact. This systematic review has identified that multimodal prehabilitation interventions are an emerging area for practice and research among men affected by prostate cancer. Importantly, there has been a lack of focus on the inclusion of partners as critical companions during this distressing phase of the cancer care continuum. For the moment, all members of the multidisciplinary team caring for people affected by prostate cancer are encouraged to use the findings in this review to inform holistic models of care.

'Pain-free TRUS B': a phase 3 double-blind placebo-controlled randomized trial of methoxyflurane with periprostatic local anaesthesia to reduce the discomfort of transrectal ultrasonography-guided prostate biopsy (ANZUP 1501).

OBJECTIVE: To determine whether the addition of inhaled methoxyflurane to periprostatic infiltration of local anaesthetic (PILA) during transrectal ultrasonography-guided prostate biopsies (TRUSBs) improved pain and other aspects of the experience. PATIENTS AND METHODS: We conducted a multicentre, placebo-controlled, double-blind, randomized phase 3 trial, involving 420 men undergoing their first TRUSB. The intervention was PILA plus a patient-controlled device containing either 3 mL methoxyflurane, or 3 mL 0.9% saline plus one drop of methoxyflurane to preserve blinding. The primary outcome was the pain score (0-10) reported by the participant after 15 min. Secondary outcomes included ratings of other aspects of the biopsy experience, willingness to undergo future biopsies, urologists' ratings, biopsy completion, and adverse events. RESULTS: The mean (SE) pain scores 15 min after TRUSB were 2.51 (0.22) in those assigned methoxyflurane vs 2.82 (0.22) for placebo (difference 0.31, 95% confidence interval [CI] -0.75 to 0.14; P = 0.18). Methoxyflurane was associated with better scores for discomfort (difference -0.48, 95% CI -0.92 to -0.03; P = 0.035, adjusted [adj.] P = 0.076), whole experience (difference -0.50, 95% CI -0.92 to -0.08; P = 0.021, adj. P = 0.053), and willingness to undergo repeat biopsies (odds ratio 1.67, 95% CI 1.12-2.49; P = 0.01) than placebo. Methoxyflurane resulted in higher scores for drowsiness (difference +1.64, 95% CI 1.21-2.07; P < 0.001, adj. P < 0.001) and dizziness (difference +1.78, 95% CI 1.31-2.24; P < 0.001, adj. P < 0.001) than placebo. There was no significant difference in the number of ≥ grade 3 adverse events. CONCLUSIONS: We found no evidence that methoxyflurane improved pain scores at 15 min, however, improvements were seen in patient-reported discomfort, overall experience, and willingness to undergo repeat biopsies.

High-dose vitamin D supplementation to prevent prostate cancer progression in localised cases with low-to-intermediate risk of progression on active surveillance (ProsD): protocol of a phase II randomised controlled trial.

INTRODUCTION: Active surveillance (AS) for patients with prostate cancer (PC) with low risk of PC death is an alternative to radical treatment. A major drawback of AS is the uncertainty whether a patient truly has low risk PC based on biopsy alone. Multiparametric MRI scan together with biopsy, appears useful in separating patients who need curative therapy from those for whom AS may be safe. Two small clinical trials have shown short-term high-dose vitamin D supplementation may prevent PC progression. There is no substantial evidence for its long-term safety and efficacy, hence its use in the care of men with PC on AS needs assessment. This protocol describes the ProsD clinical trial which aims to determine if oral high-dose vitamin D supplementation taken monthly for 2 years can prevent PC progression in cases with low-to-intermediate risk of progression. METHOD AND ANALYSIS: This is an Australian national multicentre, 2:1 double-blinded placebo-controlled phase II randomised controlled trial of monthly oral high-dose vitamin D supplementation (50 000 IU cholecalciferol), in men diagnosed with localised PC who have low-to-intermediate risk of disease progression and are being managed by AS. This trial will assess the feasibility, efficacy and safety of supplementing men with an initial oral loading dose of 500 000 IU cholecalciferol, followed by a monthly oral dose of 50 000 IU during the 24 months of AS. The primary trial outcome is the commencement of active therapy for clinical or non-clinical reason, within 2 years of AS. ETHICS AND DISSEMINATION: This trial is approved by Bellberry Ethics Committee (2016-06-459). All results will be reported in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ACTRN12616001707459.

A contemporary, nationwide analysis of surgery and radiotherapy treatment for prostate cancer.

OBJECTIVE: To characterize national clinical practice trends in the treatment of prostate cancer (PCa) in Australia. PATIENTS AND METHODS: Population-level data were extracted from existing Medicare Benefits Schedule data for radical prostatectomy (RP) and brachytherapy (2002-2016), as well as external beam radiotherapy (EBRT; 2012-2016). Treatment rates were calculated relative to whole and PCa populations among privately treated patients. Overall age-related and geographical trends were analysed. RESULTS: The use of RP and low-dose-rate (LDR) brachytherapy increased between 2002 and 2009, but subsequently decreased to 124 and 6.9 per 100 000 men, respectively, in 2016. More dramatic decreases were observed for men aged <65 years. From 2012, rates of RP (15% drop) and LDR brachytherapy (58% drop) decreased, while the use of EBRT remained steady, falling by 5% to 42 per 100 000 men in 2016. Overall treatment increased in the age group 75-84 years, with the rate of RP increasing by 108%. CONCLUSION: National claims data indicate there has been a reduction in PCa treatment since 2009, which is mostly attributable to a reduction in the treatment of younger patients and reduced use of brachytherapy. RP is most commonly used and its use is rising in men aged >65 years.

Mini-Review: What Is New in Urolift?

CONTEXT: Lower urinary tract symptoms (LUTS) are one of the most common benign conditions affecting aging men. Among surgical procedures, minimally invasive treatment options have emerged with the main objective to be at least equally effective as current standard techniques, but with a more favourable safety profile. OBJECTIVE: To present the technical principle for prostatic urethral lift (PUL) and review clinical outcomes. EVIDENCE ACQUISITION: Medline, PubMed, the Cochrane database, and Embase were screened for randomised controlled trials, clinical trials, and reviews on PUL. EVIDENCE SYNTHESIS: Data from the L.I.F.T study proved that PUL can provide rapid and durable relief of LUTS without compromising sexual function. The BPH6 trial compared PUL with transurethral resection of the prostate (TURP), and its outcomes indicated that improvement of LUTS was more pronounced after TURP, whereas PUL was superior in terms of quality of recovery, ejaculatory function, and quality of sleep. CONCLUSIONS: PUL is an attractive option for selected patients who seek rapid and durable relief of LUTS with complete preservation of sexual function and fast recovery after intervention. PATIENT SUMMARY: Prostatic urethral lift is an efficient and safe minimally invasive procedure that offers rapid and durable relief of lower urinary tract symptoms without compromising sexual function.

Perioperative antithrombotic therapy in patients undergoing endoscopic urologic surgery: where do we stand with current literature?

The number of patients on chronic anticoagulant or antiplatelet therapy requiring endoscopic urological surgery is increasing worldwide. Therefore, there is a strong demand to standardize the perioperative treatment of this cohort of patients, both from a surgical and cardiological point of view, balancing the risks of bleeding versus thrombosis, and the important possible clinical and medical legal repercussions therein. Although literature is scarce and the quality of evidence quite low, in line with other surgical specialties, guidelines and recommendations for the management of urological patients have begun to emerge. The aim of this review is to analyze current available literature and evidence on the most common endoscopic procedures performed in this high-risk group of patients, focusing on the perioperative management. In particular, to analyze the most frequently performed endoscopic procedures for the treatment of benign prostate enlargement (transurethral resection of the prostate, Thulium, Holmium and greenlight laser prostatectomy), bladder cancer (transurethral resection of the bladder), upper urinary tract urothelial cancer, and nephrolithiasis. Despite the lack of randomized studies, regardless of individual patient considerations, studies would support continuation of acetylsalicylic acid, which is recommended by cardiologists, in patients with intermediate/high risk of coronary thrombosis. In contrast, multiple studies found that bridging with light weight molecular weight heparin can potentially lead to more bleeding than continuation of the anticoagulant(s) and antiplatelet therapy, and caution with bridging is advised. All urologists should familiarize themselves with emerging guidelines and recommendations, and always be prepared to discuss specific cases or scenarios in a dedicated multidisciplinary team.

Evaluation of the changing landscape of prostate cancer diagnosis and management from 2005 to 2016.

BACKGROUND: Approaches to prostate cancer (PCa) diagnosis and treatment have evolved significantly over past decades. There has been an increasing focus on minimizing overdiagnosis and overtreatment of clinically insignificant PCa. The objective of this study was to evaluate the changes in the diagnostic approach and initial treatment strategy that has evolved over time in an Australian urological private practice. MATERIALS AND METHODS: Men with newly diagnosed PCa were identified from the private practice electronic and paper medical records from 2005 to 2016 and data was consolidated into six groups of 2-year intervals. Diagnostic strategy was analyzed with particular reference to the use of multiparametric magnetic resonance imaging (mpMRI) scan and 68Ga-prostate specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) scans. National Comprehensive Cancer Network risk group stratification was correlated with initial treatment strategy and compared over time. RESULTS: Chart review identified 839 men who had a mean age of 65.8 years. In 2011-2012, prebiopsy mpMRI scan was introduced. Its uptake correlated with a decrease in numbers of men diagnosed with low risk cancer (r = -0.80, P = 0.04) and an increase in numbers of men diagnosed with high-risk cancer (r = 0.90, P = 0.01). The use of 68Ga-PSMA PET/CT was associated with decreasing use of CT and bone scans performed. Open radical prostatectomy had a declining trend particularly when robotic surgery (robotic assisted radical prostatectomy (RARP)) was introduced. Pelvic lymph node dissections performed progressively decreased. An increased use of luteinizing hormone receptor hormone (LHRH) antagonists was seen in favor of LHRH agonists. Whilst use of high dose rate brachytherapy declined, there was an increased use of low dose rate brachytherapy. CONCLUSION: Prebiopsy mpMRI has been associated with an increased proportion of newly diagnosed men having clinically significant PCa. Over time, 68Ga-PSMA PET/CT scans, robotic assisted radical prostatectomy (RARP) and LHRH antagonists have increased in use, whilst CT and bone scans, and pelvic lymph node dissections have decreased.

Perioperative adverse events in patients on continued anticoagulation undergoing photoselective vaporisation of the prostate with the 180-W Greenlight lithium triborate laser.

OBJECTIVES: To compare perioperative factors and adverse events (AEs) in men undergoing photoselective vaporisation of the prostate (PVP) with or without continued anticoagulation therapy. PATIENTS AND METHODS: Retrospective review of a PVP database of men treated with the 180-W lithium triborate (LBO) laser from 2010 to 2016. Of 373 men, 59 underwent PVP with continued anticoagulant therapy, which was defined as treatment with heparin, warfarin, clopidogrel, dipyridamol or new oral anticoagulant drugs. Perioperative factors and AEs occurring within 90 days of surgery were analysed. RESULTS: There was no statistically significant difference in the overall incidence of perioperative AEs between those receiving and not receiving anticoagulation therapy (30.5% vs 19.9%, P = 0.07). However, there was a statistically significant difference in the incidence of high-grade Clavien-Dindo events in men who continued anticoagulation during PVP (P = 0.01). No men required blood transfusion. There was no difference in operative times and energy utilisation between the groups. In all, 53 of the 59 men in the anticoagulation group had a high-grade American Society of Anesthesiologists score, compared to 27 of the 272 men in the control group. The anticoagulation group were also significantly older. The anticoagulation group had a significantly longer length of hospital stay and duration of catheterisation compared to the controls. CONCLUSIONS: While continued anticoagulation therapy is not associated with an overall increase in perioperative AEs, it is associated with an increased rate of high-grade Clavien-Dindo events. The findings of this study suggest that there should be caution in extrapolating results about the safety profile of earlier generation lasers to the current 180-W LBO laser for patients on anticoagulation.

The massively enlarged prostate: experience with photoselective vaporization of the ≥100 cc prostate using the 180 W lithium triborate laser.

OBJECTIVES: To determine if there is a role for high-powered photoselective vaporization of the prostate (PVP) in large prostates for the management of bladder outlet obstruction. This study aims to evaluate the safety and efficacy of PVP in prostates ≥100 cc. MATERIALS AND METHODS: A retrospective analysis of a prospectively maintained database (ethics approved), single-surgeon, single-center series, between November 2010 and February 2013 of males with ≥100 cc prostates who underwent PVP. Perioperative and functional outcomes at baseline, 3, and 6 months were evaluated. RESULTS: Thirty-five males were identified, median age 70 (interquartile range [IQR] 66-79) with prostates ≥100 cc (median 132, IQR 118-157). Preoperatively, 11/35 (31%) were in urinary retention and 11/35 (31%) were anticoagulated. Perioperative outcomes showed median laser time 75 minutes, operating time 103 minutes, and energy use 750 kJ. Median postoperative length of stay was 20 hours, catheterization 12 hours, and 33/35 (94%) were discharged catheter free. Twelve adverse events in 11 men were recorded, all Clavien-Dindo Grade I-II with 1 Grade IIIa complication. Paired functional outcomes showed statistically significant (p<0.05) improvements in the median International Prostate Symptom Score (IPSS) (20, 6, 6), quality of life (QoL) Index (4, 1, 1), maximum urinary flow rate (Qmax) (9.5, 20.5, 19.5 mL/s), and postvoid residual (149, 40, 41 mL) (baseline, 3, and 6 months). CONCLUSION: PVP using the 180 W LBO laser in large prostates appears feasible and efficacious, with short duration of catheterization and postoperative length of stay. Acceptable morbidity was recorded. Enormous energy utilization was delivered within acceptable operating times. Early results indicate excellent functional outcomes at 3 and 6 months following PVP.

A Systematic Review and Meta-analysis of Functional Outcomes and Complications Following Transurethral Procedures for Lower Urinary Tract Symptoms Resulting from Benign Prostatic Obstruction: An Update.

CONTEXT: A number of transurethral ablative techniques based on the use of innovative medical devices have been introduced in the recent past for the surgical treatment of benign prostatic obstruction (BPO). OBJECTIVE: To conduct a systematic review of the literature and a meta-analysis of available randomized controlled trials (RCTs), and to evaluate the efficacy and safety of transurethral ablative procedures for BPO. EVIDENCE ACQUISITION: A systematic literature search was performed for all RCTs comparing any transurethral surgical technique for BPO to another between 1992 and 2013. Efficacy was evaluated after a minimum follow-up of 1 yr based on International Prostate Symptom Score, maximum flow rate, and postvoid residual volume. Efficacy at midterm follow-up, prostate volume, perioperative data, and short-term and long-term complications were also assessed. Data were analyzed using RevMan software. EVIDENCE SYNTHESIS: A total of 69 RCTs (8517 enrolled patients) were included. No significant difference was found in terms of short-term efficacy between bipolar transurethral resection of the prostate (B-TURP) and monopolar transurethral resection of the prostate (M-TURP). However, B-TURP was associated with a lower rate of perioperative complications. Better short-term efficacy outcomes, fewer immediate complications, and a shorter hospital stay were found after holmium laser enucleation of the prostate (HoLEP) compared with M-TURP. Compared with M-TURP, GreenLight photoselective vaporization of the prostate (PVP) was associated with a shorter hospital stay and fewer complications but no different short-term efficacy outcomes. CONCLUSIONS: This meta-analysis shows that HoLEP is associated with more favorable outcomes than M-TURP in published RCTs. B-TURP and PVP have resulted in better perioperative outcomes without significant differences regarding efficacy parameters after short-term follow-up compared with M-TURP. Further studies are needed to provide long-term comparative data and head-to head comparisons of emerging techniques. PATIENT SUMMARY: Bipolar transurethral resection of the prostate, photovaporization of the prostate, and holmium laser enucleation of the prostate have shown efficacy outcomes comparable with conventional techniques yet reduce the complication rate. The respective role of these new options in the surgical armamentarium needs to be refined to propose tailored surgical treatment for benign prostatic obstruction relief.

Current methods of analgesia for transrectal ultrasonography (TRUS)-guided prostate biopsy -- a systematic review.

Transrectal ultrasonography (TRUS)-guided prostate biopsy is the most commonly used method of sampling prostate tissue for the diagnosis of prostate cancer. The technique is well recognised to potentially cause severe pain and discomfort for patients and this has led to numerous attempts to devise ways to minimise these problems. This systematic review summarises the techniques that have been described to date, with special reference to studies using either a visual analogue or numerical analogue scale to report outcomes. Commonly used approaches that are effective to minimise pain or discomfort include intravenous sedoanalgesia, inhalational agents and periprostatic infiltration of local anaesthetic. Whilst diclofenac suppositories are more effective than placebo, intra-rectal local anaesthetic gels appear to be of no benefit. Performing TRUS-guided prostate biopsy without any form analgesia is not appropriate.

Minimally invasive prostatic urethral lift: surgical technique and multinational experience.

BACKGROUND: Many men with benign prostatic hyperplasia (BPH) are dissatisfied with current treatment options. Although transurethral resection of the prostate (TURP) remains the gold standard, many patients seek a less invasive alternative. OBJECTIVE: We describe the surgical technique and results of a novel minimally invasive implant procedure that offers symptom relief and improved voiding flow in an international series of patients. DESIGN, SETTING, AND PARTICIPANTS: A total of 102 men with symptomatic BPH were consecutively treated at seven centers across five countries. Patients were evaluated up to a median follow-up of 1 yr postprocedure. Average age, prostate size, and International Prostate Symptom Score (IPSS) were 68 yr, 48 cm(3), and 23, respectively. SURGICAL PROCEDURE: The prostatic urethral lift mechanically opens the prostatic urethra with UroLift implants that are placed transurethrally under cystoscopic visualization, thereby separating the encroaching prostatic lobes. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Patients were evaluated pre- and postoperatively by the IPSS, Quality-of-Life (QOL) scale, Benign Prostatic Hyperplasia Impact Index, maximum flow rate (Qmax), and adverse event reports including sexual function. RESULTS AND LIMITATIONS: All procedures were completed successfully with a mean of 4.5 implants without serious adverse effects. Patients experienced symptom relief by 2 wk that was sustained to 12 mo. Mean IPSS, QOL, and Qmax improved 36%, 39%, and 38% by 2 wk, and 52%, 53%, and 51% at 12 mo (p<0.001), respectively. Adverse events were mild and transient. There were no reports of loss of antegrade ejaculation. A total of 6.5% of patients progressed to TURP without complication. Study limitations include the retrospective single-arm nature and the modest patient number. CONCLUSIONS: Prostatic urethral lift has promise for BPH. It is minimally invasive, can be done under local anesthesia, does not appear to cause retrograde ejaculation, and improves symptoms and voiding flow. This study corroborates prior published results. Larger series with randomisation, comparator treatments, and longer follow-up are underway.

Photoselective vaporisation of the prostate using 80-W and 120-W laser versus transurethral resection of the prostate for benign prostatic hyperplasia: a systematic review with meta-analysis from 2002 to 2012.

CONTEXT: Photoselective vaporisation (PVP) of the prostate is being used increasingly to treat symptomatic benign prostatic hyperplasia, due to the associated lower morbidity. Holmium laser enucleation of the prostate was considered to be the treatment with the highest evidence; however, evidence for PVP has dramatically increased recently. OBJECTIVE: To conduct a systematic review and meta-analysis of level 1 evidence studies to determine the effectiveness of PVP versus transurethral resection of the prostate (TURP) for surgical treatment of benign prostatic hyperplasia. Outcomes reviewed included perioperative data, complications, and functional outcomes. EVIDENCE ACQUISITION: Biomedical databases from 2002 to 2012 and American Urological Association and European Association of Urology conference proceedings from 2007 to 2011 were searched. Trials were included if they were randomised controlled trials, had PVP as the intervention, and TURP as control. Meta-analysis was performed using a random effects model. EVIDENCE SYNTHESIS: Nine trials were identified with 448 patients undergoing PVP (80 W in five trials and 120 W in four trials) and 441 undergoing TURP. Catheterisation time and length of stay were shorter in the PVP group by 1.91 d (95% confidence interval [CI], 1.47-2.35; p<0.00001) and 2.13 d (95% CI, 1.78-2.48; p<0.00001), respectively. Operation time was shorter in the TURP group by 19.64 min (95% CI, 9.05-30.23; p=0.0003). Blood transfusion was significantly less likely in the PVP group (risk ratio: 0.16; 95% CI, 0.05-0.53; p=0.003). There were no significant differences between PVP and TURP when comparing other complications. Regarding functional outcomes, six studies found no difference between PVP and TURP, two favoured TURP, and one favoured PVP. CONCLUSIONS: Perioperative outcomes of catheterisation time and length of hospital stay were shorter with PVP, whereas operative time was longer with PVP. Postoperative complications of blood transfusion and clot retention were significantly less likely with PVP; no difference was noted in other complications. Overall, no difference was noted in intermediate-term functional outcomes.
