RESUMEN

BACKGROUND: Lower urinary tract symptoms suggestive for benign prostatic obstruction (LUTS/BPO) are one of the most frequent diseases in men and can have a significant impact on quality of life. Instrumental therapies are common, and many patients seek minimally invasive treatment options. OBJECTIVE: Presentation and evidence-based evaluation of the minimally invasive therapy for benign prostatic syndrome. MATERIALS AND METHODS: Summary and overview of chapters 11-13 on minimally invasive therapies for LUTS/BPO of the current long version of the German S2e guideline. RESULTS: In case of absolute indication for surgery or after unsatisfactory or undesired medical therapy, minimally invasive treatments such as UroLift® (Neotract Inc., Pleasanton, CA, USA), Rezá¿¡m™ (Boston Scientific, Malborough, MA, USA), iTIND™ (Olympus America Inc., Westborough, MA, USA), and prostatic artery embolization (PAE) can be considered. These indirect/delayed ablative therapies offer lower morbidity and the possibility of performing them under local anesthesia, but they are inferior to direct ablative/resective techniques in terms of effectiveness and sustainability. CONCLUSIONS: The updated German S2e guideline summarizes evidence-based recommendations for new minimally invasive therapies for LUTS/BPO, which present alternative treatment options for selected patients.

RESUMEN

Laser Techniques in the Treatment of Benign Prostatic Syndrome Abstract: Lasers have a wide range of applications in endourological therapy. Not only in the treatment of stones, but also in the treatment of benign prostatic syndrome (BPS), their importance continues to grow. The endourological treatment of BPH with different laser techniques will be discussed in more detail in the following. The physical differences between the individual lasers will be explained first, followed by the treatment options that can be performed with a laser. The main focus will be on the concrete comparison of the treatment methods, especially in clinical contexts. In particular, the duration of surgery, length of hospitalisation, risk of post-operative bleeding, catheterisation duration, risk of urinary retention and risk of post-operative complications such as retrograde ejaculation, bladder neck sclerosis, urethra stricture and adenoma recurrence will be listed and compared for the most important methods. Nevertheless, the distribution of TURP to laser is still 30:1 in favour for TURP [1].

RESUMEN

AIMS: Recently, the European Association of Urology recommended hexane-extracted fruit of Serenoa repens (HESr) in their guidelines on management of non-neurogenic male lower urinary tracts symptoms (LUTS). Despite previously lacking recommendations, Permixon® is the most investigated HESr in clinical trials, where it proved effective for male LUTS. In contrast, underlying mechanisms were rarely addressed and are only marginally understood. We therefore investigated effects of Permixon® on human prostate and detrusor smooth muscle contraction and on growth-related functions in prostate stromal cells. MAIN METHODS: Permixon® capsules were dissolved using n-hexane. Contractions of human prostate and detrusor tissues were induced in organ bath. Proliferation (EdU assay), growth (colony formation), apoptosis and cell death (flow cytometry), viability (CCK-8) and actin organization (phalloidin staining) were studied in cultured human prostate stromal cells (WPMY-1). KEY FINDINGS: Permixon® inhibited α1-adrenergic and thromboxane-induced contractions in prostate tissues, and methacholine-and thromboxane-induced contractions in detrusor tissues. Endothelin-1-induced contractions were not inhibited. Neurogenic contractions were inhibited in both tissues in a concentration-dependent manner. In WPMY-1 cells, Permixon® caused concentration-dependent breakdown of actin polymerization, inhibited colony formation, reduced cell viability, and proliferation, without showing cytotoxic or pro-apoptotic effects. SIGNIFICANCE: Our results provide a novel basis that allows, for the first time, to fully explain the ubiquitous beneficial effects of HESr in clinical trials. HESr may inhibit at least neurogenic, α1-adrenergic and thromboxane-induced smooth muscle contraction in the prostate and detrusor, and in parallel, prostate stromal cell growth. Together, this may explain symptom improvements by Permixon® in previous clinical trials.

RESUMEN

OBJECTIVES: To evaluate the impact of prostate size on functional outcomes and perioperative morbidity, we analyzed patients undergoing holmium laser enucleation of the prostate (HoLEP) for lower urinary tract symptoms (LUTS). As LUTS secondary to benign prostatic obstruction (BPO) are a chronic progressive disease, prevalence and prostate size increase with age. HoLEP is a size-independent method for surgical treatment of LUTS/BPO and can be offered in medication-refractory patients with durable long-term results and reduced perioperative morbidity. METHODS: We retrospectively collected data of 852 patients who underwent HoLEP for LUTS secondary to BPO between 2014-2018. Patients were divided into group 1 (≤60 cc), group 2 (>60 < 120 cc), group 3 (≥120 cc). Perioperative parameters, safety and short-term functional outcomes were assessed and analyzed. RESULTS: Patients in group 3 were significantly older and showed a significantly higher median prostate-specific antigen level. Perioperative parameters, such as enucleation time and morcellation time significantly differed in favor of smaller prostate sizes, while enucleation and morcellation speed showed favorable results for larger prostate sizes. Larger prostates ≥120 cc showed a significantly higher postoperative drop in hemoglobin. However, patients did not differ in postoperative functional outcomes or Clavien-Dindo grade ≥II complications (4.8% of all patients [41/852]). There was no difference in perioperative complications between all groups (P = 0.760). CONCLUSION: While larger prostates take significantly longer to operate on, postoperative functional outcomes show no difference between all sizes. In conclusion, HoLEP is a size-independent and effective method for surgical treatment of LUTS/BPO in prostates ≥30 cc.

RESUMEN

OBJECTIVE: To evaluate efficacy and safety of holmium laser enucleation of the prostate (HoLEP), bipolar enucleation of the prostate (bTUEP) and transurethral resection of the prostate (TURP) in medium-sized prostates (50cc). METHODS: We present a retrospective analysis of 2230 patients treated for lower urinary tract symptoms. We analysed perioperative parameters, short-term clinical outcomes and adverse events in matched-pair cohorts. RESULTS: Both HoLEP and bTUEP were superior in terms of efficacy compared to TURP (surgery time: 51min and 50min vs. 60min; P < 0.001; tissue retrieval percentage: 71.4% and 70% vs. 50%; P < 0.001) and showed stronger improvement of LUTS (change IPSS: -15 and -14 vs. -10; P = 0.008). Furthermore, urodynamic parameters (Qmax: +15 ml/s and +19 ml/s vs. +12 ml/s; P < 0.001; PVR: -100 ml and -95 ml vs. - 80ml; P < 0.008) were significantly more improved after enucleation than after TURP. All techniques showed an equally low complication rate (6.9% and 6.9% vs. 10.3%; P = 0.743). No relevant difference of clinical outcomes was identified between HoLEP and bTUEP. CONCLUSION: Both resection and enucleation are efficient and safe procedures in patients with medium-sized prostates (50cc), but irrespective of the technical approach, transurethral enucleation is superior to TURP in terms of perioperative and functional outcomes.

RESUMEN

Introduction: To compare holmium laser enucleation of the prostate (HoLEP) with transurethral resection of the prostate (TURP) in patients under continuous antithrombotic therapy with regard to bleeding complications. Materials and Methods: We conducted a retrospective matched-pair analysis of 221 patients with continuous antiplatelet therapy or anticoagulative medication, who were treated with HoLEP (n = 111) or TURP (n = 110). Matching criteria were prostate size (50 cc) and total surgical time (60 minutes). Patients were further stratified by their antithrombotic medication. We evaluated functional outcomes, perioperative morbidity, and bleeding complications according to Clavien-Dindo (CD). Results: Our perioperative assessment showed a significantly higher percentage of resected tissue for HoLEP (median 71.43%; interquartile range [IQR]: 61.82-78.57) than for TURP (median 45.45% IQR: 39.02-56.20) (p < 0.001). Total perioperative hemoglobin drop was significantly lower for the HoLEP cohort (median 0.7 g/dL; IQR: 0.3-1.1 g/dL) than for the TURP cohort (median 2.20 g/dL; IQR: 1.18-2.80 g/dL) (p < 0.001). For all subgroups, perioperative blood loss was always significantly lower for HoLEP than for TURP. The median hemoglobin drop was 0.5 g/dL vs 1.1 g/dL for the acetylsalicylic acid 100 mg (ASS) subgroup, 0.70 g/dL vs 2.95 g/dL for the ASS+ADP-receptor inhibitor subgroup, 0.65 g/dL vs 2.4 g/dL for the vitamin K antagonist subgroup, and 0.90 g/dL vs 2.70 g/dL for the direct oral anticoagulant subgroup (all, p < 0.001). Perioperative adverse events were significantly less frequent after HoLEP (5.4%) than after TURP (16.4%) (p < 0.05). Conclusion: HoLEP is an efficient and safe procedure for patients under diverse continuous antithrombotic regimens. It provides a superior perioperative hemostatic control and causes less bleeding complications in this high-risk population.

RESUMEN

PURPOSE: To assess the impact of previous transurethral surgery for benign prostate enlargement (BPE) and time interval between procedures on functional outcomes and health-related quality of life (HRQOL) after radical prostatectomy (RP). METHODS: A propensity score-matched patient cohort [n = 685, (513 without previous BPE surgery, 172 with BPE surgery)] was created and HRQOL was pre- and postoperatively assessed using validated questionnaires (EORTC QLQ-C30). Urinary continence was measured via ICIQ-SF questionnaire and pad usage. Multivariable analysis included binary logistic and Cox regression models (p < 0.05). RESULTS: Median follow-up was 18 months. There was no significant difference in recurrence-free survival in multivariate analysis (HR 0.66, 95%CI 0.40-1.07, p = 0.093). We observe higher mean ICIQ-SF scores (5.7 vs. 8.2, p < 0.001) and daily pad usage (1.3 vs. 2.5, p < 0.001), and decreased continence recovery (OR 0.46, 95%CI 0.30-0.71, p < 0.001) for patients with BPE surgery. Postoperative general HRQOL scores were significantly lower for patients with previous BPE surgery (70.6 vs. 63.4, p = 0.003). In multivariate analysis, continence recovery (OR 5.19, 95%CI 3.10-8.68, p < 0.001) but not previous BPE surgery (0.94, 0.57-1.54, p = 0.806) could be identified as independent predictors of good general HRQOL. There was no significant correlation between time interval between both surgeries and continence (p = 0.408), and HRQOL (p = 0.386) outcomes. CONCLUSIONS: We observe favourable continence outcomes for patients without previous BPE surgery. Our results indicate that RP can be safely performed after transurethral BPE surgery, regardless of the time interval between both interventions.

RESUMEN

OBJECTIVES: With holmium laser enucleation of the prostate (HoLEP) a size-independent method for surgical treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO) has been introduced. HoLEP offers durable long-term results with reduced perioperative morbidity. As the risk of disease progression increases with age, the main goals, when offering surgery to an elderly population, are reducing perioperative morbidity and preserving quality of life (QoL). We therefore analyzed the impact of age on outcomes and perioperative morbidity in patients undergoing HoLEP for LUTS at our tertiary referral center. METHODS: We retrospectively collected data of 487 patients who underwent HoLEP for LUTS secondary to BPO between 2018 and 2019. Patients were divided into group 1 (<70 years), group 2 (70-79 years), and group 3 (≥80 years). Perioperative parameters, safety, and short-term functional outcomes were assessed and analyzed. RESULTS: Perioperative Clavien-Dindo grade ≥II complications were seen in 4.1% of patients (20/487). There was no difference in perioperative complications between all age groups (P = .176). Functional outcome was assessed 30 days post surgery. There was significant improvement in median International Prostate Symptom Score of 14, 10, and 8 points for groups 1, 2, and 3 (P < .001), respectively, with constant improvement of median QoL of 3 points for all groups. Median maximum flow rate (Qmax ) showed significant improvement of 14.5, 10.5, and 13 mL/s for groups 1 to 3 (P = .467), respectively. CONCLUSION: HoLEP offers acceptable perioperative complication rates even in the oldest patient cohort (≥80 years). Therefore, HoLEP is a safe and efficient option even in oldest patients.

RESUMEN

OBJECTIVES: To evaluate perioperative parameters, early functional outcomes, and the safety profile in a matched-pair analysis of lower urinary tract symptom (LUTS) patients treated with holmium laser enucleation of the prostate (HoLEP) or transurethral resection of the prostate (TURP). METHODS: We conducted a retrospective, matched-pair analysis of 2011 men treated for LUTS in our institution from 2013 to 2017. In the final analysis, 197 patients (HoLEP n = 97; TURP n = 98) were matched for prostate size (50 cc), age, and body mass index, and both cohorts were compared for demographic parameters, clinical outcomes, and adverse events according to the Clavien-Dindo classification. RESULTS: The perioperative assessment revealed a significantly higher tissue retrieval percentage of 75.4% (interquartile range [IQR] 64-81.2) after HoLEP in comparison to 47.3% (IQR 40-54.7) after TURP (P <.001). A shorter surgery time was reported for TURP with a median time of 55.5 minutes (IQR 48-70.5), whereas the median time for HoLEP was 62 minutes (IQR 51-85) (P =.006). The median improvements in International Prostate Symptom Score (IPSS) were 11 points (IQR 5.5-17) and 7 points (IQR 3-14) for HoLEP and TURP, respectively (P =.007). Peak urinary flow rate (Qmax ) increased more after HoLEP (12.0 mL/s; IQR 7-23) than after TURP (8.5 mL/s; IQR 5-18.25) (P =.028). With an overall incidence of adverse events of 6% (n = 6) compared to 16% (n = 16%), significantly fewer complications occurred after HoLEP than after treatment with TURP (P <.05). CONCLUSIONS: HoLEP is not only an attractive alternative for the enucleation of larger prostates, but it must be considered a size-independent technique with the potential to outdo the current reference method TURP.

RESUMEN

PURPOSE: To analyse the therapeutic efficacy of various phytotherapeutics and their antimicrobial compounds with regard to strain specificity and dose dependence. METHODS: A representative strain collection of 40 uropathogenic bacteria isolated from complicated and uncomplicated urinary tract infection was subjected to various virulence assays (bacterial growth, mannose-sensitive agglutination, and motility) to determine the therapeutic impact of various compounds with antimicrobial activity. We tested proanthocyanidins (PAC), D-mannose, rosemary extract (Canephron®), and isothiocyanates (Angocin®). RESULTS: D-mannose efficiently blocked the adhesive properties of all type 1 fimbriae-positive isolates in low concentration (0.2%), but showed no bacteriostatic effect. PAC also actively blocked agglutination, but the concentration varied considerably among isolates. Escherichia coli required the highest concentration (10%), while Enterobacter cloacae responded to low concentrations (0.1%). Allyl isothiocyanates not only impaired agglutination in all tested isolates, but also had a dramatic impact on flagella-mediated motility in Escherichia coli, Klebsiella pneumoniae, and Proteus mirabilis (p < 0.001). The administration of rosemary extracts revealed a strong bacteriostatic effect in growth assays. All tested strains were strongly inhibited by the addition of 10 µg/ml or 1 µg/ml of purified rosemary extractions with the exception of Serratia marcescens. Morganella morganii responded only to 10 µg/ml. CONCLUSION: Phytotherapeutics and small-molecular compounds like mannosides have the potential to become an integral part in a multi-modal treatment concept for the treatment and prevention of urinary tract infections. Their efficiency can be optimised when strain specificities and therapeutic concentrations are taken into account.

RESUMEN

Minimally-invasive treatment options for patients with LUTS due to benign prostatic obstruction (BPO) become more and more important because they provide equal long-term efficacy compared with the reference method TURP, while having a more favourable safety profile. There are promising results for PUL (Prostatic Urethral Lift - UroLift) with low complication rates. UroLift is clearly superior regarding the preservation of sexual functions without impairment of ejaculatory function.

RESUMEN

The main objective of novel minimally invasive treatment options is to be equally effective to current reference techniques while providing a superior safety profile. Especially the preservation of sexual function, including ejaculatory function, is of great interest to patients facing surgical treatment of lower urinary tract symptoms (LUTS). Ideally, a truly minimally invasive procedure can be performed under local anaesthesia in an outpatient setting. Among emerging medical devices, the prostatic urethral lift (PUL; Urolift) demonstrated rapid and durable relief of LUTS in selected patients without a prominent middle lobe. Compared to the reference method TURP, it was superior in terms of preservation of sexual function and recovery experience. The first clinical evaluation of the "Temporary Implantable Nitinol Device" (TIND) proved its feasibility, efficacy and safety for the treatment of LUTS over a 3-year follow-up period. However, prospective randomised controlled trials are still needed to evaluate its true benefit. New ablative technologies like Rezum are based on convective water vapour energy and have shown good results in a sham-controlled randomised clinical trial for the treatment of LUTS over a follow-up period of 3 years. Of note, this procedure was also successful in patients with a prominent middle lobe, and no impairment of sexual function was reported after Rezum. Innovative technologies like Aquablation (AquaBeam) are still in their infancy, but the first clinical outcomes are promising, even in comparison with the reference method TURP.

RESUMEN

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.

RESUMEN

The key of success of extraintestinal pathogenic Escherichia coli (ExPEC) to colonize niches outside the intestinal tract and to establish infection is the coordinated action of numerous virulence and fitness factors. The so-called high-pathogenicity island (HPI), responsible for synthesis, secretion and uptake of the siderophore yersiniabactin, proved to be an important virulence determinant. In this study we investigated the interaction of the flagellum-mediated motility and the HPI. The impairment of yersiniabactin production by deletion of irp2 or ybtA affected significantly motility. The gain of yersiniabactin production improved motility in both pathogenic and non-pathogenic E. coli strains. The loss of flagella expression had no adverse effect on the HPI. Strikingly, external iron abundance was not able to suppress activation of the HPI during motility. The HPI activity of swarming bacteria was comparable to iron deplete conditions, and could even be maximized by supplementing excessive iron. This fact is the first description of a regulatory mechanism, which does not follow the known hierarchical regulation of siderophore systems. Transcriptional reporter fusions of the ybtA promoter demonstrated that the entire promoter region with all YbtA binding sites is necessary for complete induction in both HPI-positive and HPI-negative strains. Altogether, these results suggest that the HPI is part of a complex regulatory network, which orchestrates various virulence mechanisms to optimize the overall fitness of ExPEC.

RESUMEN

Lower urinary tract symptoms (LUTS) due to benign prostatic enlargement (BPE) represent one of the most common bothersome conditions impairing quality of life in men. Its management comprises conservative treatment, pharmacotherapy, and various surgical techniques. Medication and surgical procedures provide meaningful relief of LUTS, but their therapeutic efficacy has to be counterbalanced against the associated adverse events and morbidity. With the advent of novel minimally invasive treatment options, the surgical standards are challenged for at least equally effective approaches with a much more favorable safety profile. Clinical randomized controlled trials confirmed that PUL is able to provide rapid and durable relief of LUTS without compromising sexual function. However, in order to define the value and true benefit of a novel technique among established surgical procedures, the direct comparison with the reference method TURP is necessary. This was the main objective of the BPH6 study, which evaluated symptom relief, recovery experience, sexual function, urinary continence, and safety of PUL compared to TURP. Over a 2-year follow-up, no relevant negative impact on erectile function, urinary continence, and treatment-related safety was observed for both procedures. Improvement of LUTS was better after TURP, whereas PUL turned out to be superior in terms of quality of recovery, ejaculatory function, and quality of sleep. PUL can be considered in selected patients with bothersome LUTS, with special interest in the complete preservation of sexual function and a rapid and smooth return to daily activity.

RESUMEN

PURPOSE: To evaluate oncologic parameters of men with bothersome LUTS undergoing surgical treatment with HoLEP or TURP. METHODS: Five hundred and eighteen patients undergoing HoLEP (n = 289) or TURP (n = 229) were retrospectively analyzed for total PSA, prostate volume, PSA density, history of prostate biopsy, resected prostate weight, and histopathological features. Univariate and multivariate logistic regression models were used to identify independent predictors of incidental PCa (iPCa). RESULTS: Men undergoing HoLEP had a significantly higher total PSA (median 5.5 vs. 2.3 ng/mL) and prostate volume (median 80 vs. 41 cc), and displayed a greater reduction of prostate volume after surgery compared to TURP patients (median 71 vs. 50%; all p < 0.001). With a prevalence of incidental PCa (iPCa) of 15 and 17% for HoLEP and TURP, respectively, the choice of procedure had no influence on the detection of iPCa (p = 0.593). However, a higher rate of false-negative preoperative prostate biopsies was noted among iPCa patients in the HoLEP arm (40 vs. 8%, p = 0.007). In multivariate logistic regression, we identified patient age (OR 1.04; 95% CI 1.01-1.07, p = 0.013) and PSA density (OR 2.13; 95% CI 1.09-4.18, p = 0.028) as independent predictors for the detection of iPCa. CONCLUSIONS: Despite differences in oncologic parameters, the choice of technique had no influence on the detection of iPCa. Increased patient age and higher PSA density were associated with iPCa. A higher rate of false-negative preoperative prostate biopsies was noted in HoLEP patients. Therefore, diagnostic assessment of LUTS patients requires a more adapted approach to exclude malignancy, especially in those with larger prostates.

RESUMEN

CONTEXT: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition that causes severe symptoms, bother, and quality-of-life impact in the 8.2% of men who are believed to be affected. Research suggests a complex pathophysiology underlying this syndrome that is mirrored by its heterogeneous clinical presentation. Management of patients diagnosed with CP/CPPS has always been a formidable task in clinical practice. Due to its enigmatic etiology, a plethora of clinical trials failed to identify an efficient monotherapy. OBJECTIVE: A comprehensive review of published randomized controlled trials (RCTs) on the treatment of CP/CPPS and practical best evidence recommendations for management. EVIDENCE ACQUISITION: Medline and the Cochrane database were screened for RCTs on the treatment of CP/CPPS from 1998 to December 2014, using the National Institutes of Health Chronic Prostatitis Symptom Index as an objective outcome measure. Published data in concert with expert opinion were used to formulate a practical best evidence statement for the management of CP/CPPS. EVIDENCE SYNTHESIS: Twenty-eight RCTs identified were eligible for this review and presented. Trials evaluating antibiotics, α-blockers, anti-inflammatory and immune-modulating substances, hormonal agents, phytotherapeutics, neuromodulatory drugs, agents that modify bladder function, and physical treatment options failed to reveal a clear therapeutic benefit. With its multifactorial pathophysiology and its various clinical presentations, the management of CP/CPPS demands a phenotypic-directed approach addressing the individual clinical profile of each patient. Different categorization algorithms have been proposed. First studies applying the UPOINTs classification system provided promising results. Introducing three index patients with CP/CPPS, we present practical best evidence recommendations for management. CONCLUSIONS: Our current understanding of the pathophysiology underlying CP/CPPS resulting in this highly variable syndrome does not speak in favor of a monotherapy for management. No efficient monotherapeutic option is available. The best evidence-based management of CP/CPPS strongly suggests a multimodal therapeutic approach addressing the individual clinical phenotypic profile. PATIENT SUMMARY: Chronic prostatitis/chronic pelvic pain syndrome presents a variable syndrome. Successful management of this condition is challenging. It appears that a tailored treatment strategy addressing individual patient characteristics is more effective than one single therapy.
