Mykoniatis I, Renterghem KV, Sokolakis I. How can we Preserve Sexual Function after Ablative Surgery for Benign Prostatic Hyperplasia? Curr Drug Targets 2020; 22:4-13. [PMID: 32981500 DOI: 10.2174/1389450121666200925143916] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2020] [Revised: 05/28/2020] [Accepted: 07/08/2020] [Indexed: 12/22/2022]
Abstract
Our aim was to provide a narrative review regarding the prevalence, the associated pathophysiologic pathways and the potential management methods of sexual dysfunction related to ablative surgical techniques for Benign Prostatic Enlargement (BPE). Men suffering from BPE are at high risk of sexual dysfunction due to the disease itself, comorbidities, and pharmacological/surgical treatments. Transurethral resection of the prostate, as the gold standard treatment option for BPE, has historically been associated with relatively high rates of postoperative sexual dysfunction problems, mainly retrograde ejaculation but also erectile dysfunction. Ablative surgical techniques, including photoselective vaporization of the prostate (PVP), transurethral needle ablation (TUNA), Transurethral Microwave Therapy (TUMT), Convective Water Vapor Energy Ablation (Rezum®) and Aquablation®, have been proposed as treatment methods able to reduce treatment-related complications for BPE patients, including adverse effects on erectile and ejaculatory function, without compromising the efficacy rates for BPE. The neurovascular bundles can be damaged during TURP due to posterolateral capsular perforation. Ablative techniques and especially PVP theoretically seem to skip this hazard, as the distance created from the necrotic area to the capsule is generally larger compared to the distance induced after TURP. However, indirect thermal injury of erectile nerves, which could also be induced by the majority of available ablative techniques, could potentially lead to ED. Two special technical characteristics (physiological saline use for tissue ablation and real time penetration depth control) of Aquablation® could be proved beneficial with regard to the effect of the method on erectile function. In general, ablative techniques seem to have a minor impact on sexual function. However, low methodological quality characterizes most of the studies included in this review mainly due to the impossibility, in many cases, to perform blind randomization. Also, many studies did not have an erectile and ejaculatory function as primary outcomes limiting that way their statistical power to identify significant variations. Management of sexual dysfunction problems arising from ablative surgeries for BPE treatment could be divided into two levels. Firstly, intraoperatively the avoidance of manipulation of crucial structures regarding ejaculatory (bladder neck or ejaculatory ducts) and erectile function (neurovascular bundles) could possibly decrease the negative effect of these procedures on sexual function. Thus, in this direction, modifications of classic ablative techniques have been proposed resulting in encouraging outcomes regarding postoperative sexual function. Secondly, if EjD and/or ED are established, the already known treatment choices should be chosen in order for sexual function rehabilitation to be achieved. Thus, regarding ED: PDE5i daily or on-demand remains the gold standard first-line treatment choice followed by intracavernosal alprostadil injections in cases of failure, while penile prosthesis implantation must be kept as the final definitive solution when all the other methods have failed. Regarding ejaculation disorders (retrograde ejaculation or anejaculation): medical therapy with a-agonists (pseudoephedrine), sperm retrieval from the urine, bladder neck reconstruction, prostatic massage, electroejaculation, penile vibratory stimulation and surgical sperm retrieval are the available treatment options. Furthermore, high-quality studies are required to investigate the potential side effects of BPE surgery on sexual function and efficient treatment methods to manage them.

Abstract
Purpose To evaluate the impact of photoselective vaporization of the prostate (PVP) with a 120-W GreenLight high-performance system on erectile function in a 2-year follow-up study. Materials and Methods One hundred seventy-seven patients who underwent PVP during 2008 to 2012 were analyzed retrospectively. The patients were divided into 5 groups according to their preoperative 5-item International Index of Erectile Function (IIEF-5) scores: Group I (IIEF-5: 5~7, n=28), II (IIEF-5: 8~11, n=47), III (IIEF-5: 12~16, n=43), IV (IIEF-5: 17~21, n=34), and V (IIEF-5: 22~25, n=25). The patients were assessed before surgery and 6, 12, and 24 months after the PVP. Their International Prostate Symptom Score/quality of life, maximum urinary flow rate/post-void residual urine volume, and IIEF-5 scores were measured at each visit. Results The mean age and presence of hypertension were significantly different among the 5 groups. Perioperative parameters and postoperative complication rates showed no statistical differences. After PVP, voiding parameters were significantly improved in all the groups and sustained during the 2-year follow-up. The postoperative IIEF-5 scores fell slightly overall, while group V showed the largest significant deterioration. In multivariate analysis, body mass index (BMI) was the only independent predictor of decreased erectile function after PVP. Conclusions Erectile function declined in all the groups after PVP, with the most extensive deterioration observed in patients with normal erectile function preoperatively. Preoperative BMI was the only independent risk factor for a meaningful decrease in erectile function after PVP.

Abstract
Benign prostatic hyperplasia (BPH) is a common pathology causing lower urinary tract symptoms (LUTS) and may significantly impact quality of life. While transurethral resection of the prostate (TURP) remains the gold standard treatment, there are many evolving technologies that are gaining popularity. Photoselective vaporization of the prostate (PVP) is one such therapy which has been shown to be non-inferior to TURP. We aimed to review the literature and discuss factors to optimise patient outcomes in the setting of PVP for BPH. A comprehensive search of the electronic databases, including MEDLINE, Embase, Web of Science and The Cochrane Library was performed on articles published after the year 2000. After exclusion, a total of 38 papers were included for review. The evolution of higher powered device has enabled men with larger prostates and those on oral anticoagulation to undergo safely and successfully PVP. Despite continued oral anticoagulation in patients undergoing PVP, the risk of bleeding may be minimised with 5-Alpha Reductase Inhibitor (5-ARI) therapy however further studies are required. Pre-treatment with 5-ARI’s does not hinder the procedure however more studies are required to demonstrate a reliable benefit. Current data suggests that success and complication rate is largely influenced by the experience of the operator. Post-operative erectile dysfunction is reported in patients with previously normal function following PVP, however those with a degree of erectile dysfunction pre-operatively may see improvement with alleviation of LUTS.

Abstract
This study aimed to evaluate the impact of thulium:yttrium-aluminum-garnet (Tm:YAG) (RevoLix®) laser prostatectomy for the treatment of benign prostatic obstructions on erectile function (EF). A total of 208 patients who underwent Tm:YAG laser prostatectomies participated in this study. All cases were evaluated preoperatively and at 3, 6, and 12 months postoperatively using the International Prostate Symptom Score (IPSS), quality of life (QoL) score, and the International Index of Erectile Function (IIEF-5) questionnaires. Patients were divided into groups A (severe erectile dysfunction [ED]), B (moderate ED), and C (mild-to-normal ED), according to their IIEF-5 scores. The median patient ages were 69, 65, and 62 years in groups A, B, and C, respectively. Significant improvements occurred in the IPSS and QoL score within the groups during the 12-month follow-up period. The IIEF-5 scores at 3 months postoperatively were lower than the preoperative scores in groups B and C. The IIEF-5 scores subsequently improved during the 12-month follow-up period. The slope of the relationship between the IIEF-5 score and the time since Tm:YAG laser prostatectomy had a ß value of 0.2210 (95% confidence interval 0.103 to 0.338, p = 0.0003); hence, each postoperative month was associated with an increase of 0.2210 in the IIEF-5 score. The IIEF-5 scores gradually increased and reached the preoperative levels by the 12-month follow-up assessment. Although the IIEF-5 score dropped significantly during the first 3 months postoperatively, it improved over the following 12 months. Tm:YAG laser prostatectomy did not impact on EF ultimately.

Abstract
Treatment of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) may affect the quality of sexual function and ejaculation. The effect of new surgical procedures, which are currently available to treat BPH, on erection and ejaculation, has been poorly studied. This study aimed to assess the effect of thulium laser enucleation of the prostate (ThuLEP) on sexual function and retrograde ejaculation in patients with LUTS secondary to BPH. We performed a prospective study in 110 consecutive patients who had undergone ThuLEP to analyze changes in sexual function and urinary symptoms. To evaluate changes in erection and ejaculation, and the effect of urinary symptoms on the quality of life (QoL), five validated questionnaires were used: the ICIQ-MLUTSsex, MSHQ-EjD, International Index of Erectile Function 5, International Prognostic Scoring System (IPSS) questionnaire, and QoL index of the intraclass correlation coefficients. Patients also underwent IPSS and flowmetry to assess the outcome of flow. Patients were evaluated before surgery and 3–6 months after ThuLEP, whereas those with previous abdominal surgery were excluded. The patients’ mean age was 67.83 years. Postoperative urinary symptoms improved after surgery. No significant differences in erectile function before and after surgery were observed. As compared with other techniques described in the literature, the percentage of patients with conserved ejaculation increased by 52.7% after ThuLEP. ThuLEP positively affects urinary symptoms and their effect on the QoL of patients as assessed by questionnaire scores. While endoscopic management of BPH (e.g. transurethral resection of the prostate) causes retrograde ejaculation in most patients, those who undergo ThuLEP have conserved ejaculation and erectile function.

Abstract
INTRODUCTION Lower urinary tract symptoms (LUTS) because of benign prostatic hyperplasia (BPH) are a highly prevalent condition in men over 50 years old, and their incidence increases with age. The relationship between LUTS and erectile dysfunction (ED) has received increased attention recently because both diseases are highly prevalent, frequently co-associated in the same aging male group, and contribute significantly to the overall quality of life. In this review, we will examine the literature to assess the impact of surgical and minimally invasive treatments for LUTS/BPH on the male's sexual health. METHODS The impact of the various surgical and minimally invasive treatments for LUTS/BPH was reviewed to ascertain the impact on erectile and ejaculatory function. RESULTS Sexual side effects of treatment for LUTS/BPH are underappreciated by urologists but likely play a prominent role in patient decision making, creating a disparity between provider and patient. Almost all accepted therapies for LUTS (surgical or medical) can affect some aspect of sexual health, making it imperative that health-care professionals understand their patients' concerns and motivations in these two linked diseases. The incidence of newly diagnosed postoperative ED in patients treated with monopolar transurethral resection (TURP) is around 14%, with reported values in various studies ranging from 0-32.5%, 7.7%, 6.5%, 17%, to 14%. Importantly, there is no significant difference reported between bipolar and monopolar TURP on sexual function. CONCLUSION The risk of sexual side effects is an important one to consider in discussing the implications for any LUTS intervention as they play a prominent role in patient motivation, acceptance of bother and decision making concerning surgical intervention, thus creating a potential disparity between provider and patient.

Abstract
PURPOSE The aim of this study is to investigate the efficacy and safety of 180-W XPS GreenLight laser technology for photoselective prostate vaporization. PATIENTS AND METHODS A systematic search of the electronic databases was performed. Inclusion criteria were: full-text peer-reviewed journal article, with original data analysis that evaluates the feasibility and the outcome only of 180-W XPS GL laser system. Data at baseline and during follow-up have been taken into account. Intra-operative and postoperative (functional results and complications) data were collected and analyzed. RESULTS We found 165 articles in our research, among which only nine articles were selected (total 991 patients). A certain grade of variability is present in all the studies in terms of scientific design, sample size and methods of reporting functional results and complications. Nevertheless, a homogenous benefit for patients in terms of symptom score improvement, post-void residual volume reduction and urinary max flow rate improvement was shown. According to Clavien-Dindo classification, 292 (83.7%) adverse events were recorded ≤ grade 2. Adverse events ≥ grade 3 were 57 (16.3%), among which bleeding, urinary retention and residual obstructive tissue represented the wide majority. No mortality was reported. Male sexual function was poorly investigated. CONCLUSIONS The 180-W XPS GL laser technique is feasible and safe, with a remarkable clinical benefit. Long-term evidence on outcomes and complications are suitable even in the sphere of male sexuality.

Abstract
Transurethral resection of prostate (TURP) has long been the most commonly performed surgical procedure for the management of benign prostate enlargement (BPE), but has several associated limitations. Over the years, laser techniques have developed as major contenders as alternative therapies for BPE. However, simultaneously, TURP has also flourished and with relatively recent development of resection in saline (bipolar TURP), the tussle between laser techniques and TURP has further gained momentum. A systematic search was performed on Medline using the various Medical subject headings related to the surgical management of BPE including TURP, bipolar, lasers, holmium laser enucleation of prostate (HoLEP), photo-selective vaporization of prostate (PVP), etc., All articles types including meta-analysis randomized controlled trials, review articles, guidelines from various urological associations, single center studies from 2002 onward were considered for review. Bipolar TURP, HoLEP, and PVP provide equivalent outcomes for large prostate adenoma (<60 g). For extremely large glands (<150 g), HoLEP is a very efficacious endoscopic alternative to open prostatectomy and has proven long-term results over more than a decade. Bipolar TURP and PVP are attractive with a minimal learning curves and equivalent short term durability. Surgical management of large prostate should be individualized based upon patient's comorbidities and surgeon's expertise.

Abstract
INTRODUCTION A better understanding of ejaculatory disorders has led to an increasing interest in nonpremature ejaculatory dysfunction (non-PE EjD). Current reviews on the subject use a symptom-based classification to describe ejaculatory dysfunction even when it is a single case report. While these reviews provide important information on the disorder, a clearer picture of the prevalence of non-PE EjD in relation to the community and various pathophysiologic states is needed. OBJECTIVES The objective of this study was to provide a systematic review of studies of non-PE EjD excluding single case reports. METHODS A systematic review of Medline for terms including ejaculation, orgasm or hematospermia. Association with terms delay, pain or headache was made. The search was restricted to male gender and articles written in English. Abstracts were reviewed and those mainly concerned with premature ejaculation were excluded. RESULTS A total of 333 articles on non-PE EjD were identified. The condition was reported in community-based studies. In certain patient populations, non-PE EjD was commonly reported in association with antidepressant and antipsychotic treatments, in patients with chronic prostatitis/chronic pelvic pain syndrome, patients with lower urinary tract symptoms particularly in association with medical or surgical treatment, patients with retroperitoneal surgery and in patients with neurological diseases. Few articles were concerned with treatment options. CONCLUSION There is a significant prevalence of non-PE EjD in the community and in association with particular disease states or as a side effect of medical or surgical interventions. There is a need to direct efforts to prevent and treat these conditions.

Abstract
Abstract Background and Purpose: Photoselective vaporization of the prostate (PVP) has emerged as a minimally invasive alternative to transurethral resection of the prostate for treatment of benign prostate hyperplasia (BPH) with lower urinary tract symptoms (LUTS). Very few prospective studies have addressed the effect of PVP on sexual function. We performed this prospective study to assess the short-term effect of PVP on erectile function in patients who present with LUTS secondary to BPH. Patients and Methods: There were 150 consecutive patients who presented with LUTS secondary to BPH who underwent PVP and who were enrolled prospectively in this study. Patients were categorized in two groups: Group A, International Index of Erectile Function (IIEF) ≥19; group B, IIEF <19. PVP was performed by using an 80 W GreenLight laser. Patients preoperative, perioperative, and follow-up data were recorded. Erectile function was assessed preoperatively and postoperatively at 1, 3, 6, and 12 months using IIEF-5. In follow-up, Ultrasonography of the kidneys, ureters, and bladder for residual prostate and postvoid residual urine, uroflowmetry, kidney function tests, and urine culture were performed at each visit. Cystoscopy was performed at 3 months. Data were analyzed statistically. Results: The two patient groups were comparable in their preoperative and perioperative data. Both groups showed improvement in International Prostate Symptom Score, maximum flow rate, quality of life, and decrease in postvoid residual urine at 1, 3, 6, and 12 months with no statistical significance. IIEF-5 scores in Group A, however, were 21.1, 19.2, 17.1, 16.2, and 16.1, respectively, at preoperative, postoperative month 1, 3, 6, and 12, respectively (P=0.02). IIEF-5 scores in Group B were 13.2, 12.1, 11.3, 11.2, and 10.9, respectively, at preoperative, postoperative month 1, 3, 6, and 12, respectively (P=0.45). Conclusions: In patients with normal preoperative erectile function, PVP resulted in significant decrease in EF up to follow-up of 1 year. In patients with preoperative ED, however, PVP did not significantly decrease EF.
