RESUMO
PURPOSE: Prostatic urethral lift has been an effective ejaculation sparing treatment for benign prostatic hypertrophy. The aim of this study was to evaluate the effect on male semen parameters. METHODS: Between July 2014 and January 2022, 20 young men with urinary symptoms of BPH, unresponsive to drug treatment and motivated to preserve ejaculation for eventual paternity, underwent UroLift. Semen analysis was performed before and 6 month after surgery with evaluation of pH, volume, sperm concentration, total motility, vitality and morphology according to WHO 2011. All underwent digital rectal examination, transrectal prostate ultrasound to measure prostate volume, PSA, uroflowmetry, cystoscopy and urodynamics test if necessary. Objective and subjective urinary function was scheduled at 1, 3, 6, 12 month than yearly with UFM, IPSS, IIEF-5, and MSHQ-EjD-SF. RESULTS: At a mean follow-up of 36 month (range 12 to 63), no retroejaculation or changes in seminal parameters occurred. Mean age was 44.5 (range 36.5 to 48) years. Mean operative time was 15 (range 10 to 20) min and 2.5 (range 2 to 4) implants per patients were used. At 6 month there were no difference in terms of total sperm count, volume, pH, motility, vitality, morphology, liquefaction, leucocytes (p = 0.9; p = 0.8; p = 0.7; p = 1; p = 1; p = 1; p = 0,2; p = 0.5). At last, Q-max increased by 64.4% (p = 0.001), post-void residual volume decreased by 66.6% (p = 0.016), and IPSS decreased by 60% (p < 0.001). IIEF and MSHQ-EjD-SF were preserved (p = 0.14, p = 0.4). CONCLUSIONS: UroLift appears safe technique to correct LUTS from BPH in young men desirous to preserve seminal analysis.

PURPOSE: This study identified risk factors for neurogenic lower urinary tract dysfunction (NLUTD) in patients with acute ischemic stroke (AIS) through multidimensional analysis of the medical records of patients, aiming to reduce the incidence of NLUTD, improve prognosis, and facilitate rehabilitation. MATERIALS AND METHODS: In this case-control study, patients with AIS were recruited from two tertiary general hospitals in Shenzhen, China, from March 2021 to October 2023. Patients were divided into NLUTD and non-NLUTD groups based on the presence and absence of NLUTD, respectively. Comparative analysis was performed using the Mann-Whitney U and chi-square tests, with significant variables being included in logistic regression analysis. RESULTS: Of the 652 participants enrolled in this study, 119 participants (18.3%) developed NLUTD. Bivariate analysis showed that 39 of 54 screened factors exhibited a significant correlation (p<0.05) with the incidence of NLUTD after AIS. Significant variables identified through logistic regression analysis included Glasgow coma scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) scores, anemia, aphasia, pneumonia, brainstem involvement, multiple lesions, urine clarity (CLA), random venous blood glucose (GLU) and hemoglobin (HGB) levels, and white blood cell (WBC) count. CONCLUSIONS: A total of 11 risk factors for NLUTD were identified in this study. This finding provides valuable guidance for reducing the incidence of NLUTD after AIS and improving the quality of life of patients.

PURPOSE: The management of bowel bladder disorder (BBD) has only been indicated for subjective constipation without objective evidence. We attempted to highlight the radiological findings in patients with BBD and construct a scoring system to identify patients with BBD prior to treatment. MATERIALS AND METHODS: Forty-five patients with lower urinary tract dysfunction (LUTD) received polyethylene glycol for 2 months before bladder medication for LUTD. Based on partial response to LUTD following treatment, we divided the patients into LUTD-fecal impaction (FI) and LUTD not attributed to FI (LUTD-NFI) groups. Pre/post-treatment kidney, ureter, and bladder (KUB) were compared with respect to several radiographic parameters. Items with significant changes after treatment were included in the scoring system. The accuracy and inter-rater agreement were also evaluated. RESULTS: Cecal dilation, descending colon dilation, fecal quality, and overall haziness were found to undergo significant changes after laxative treatment. We assigned 0 to 2 points for each item, with a total score of 8. Receiver operating characteristic curve analysis revealed a cutoff value of 5 between LUTD-FI and LUTD-NFI, with 79% sensitivity and 88% specificity. The scoring system was instructed to six doctors who were unaware of it and was then tested on previous patients, which showed a substantial concordance rate (κ=0.79, p<0.05). CONCLUSIONS: Fecal scoring system based on KUB was beneficial in identifying children with LUTD attributed to FI. This may provide an opportunity to obtain objective FI data as an alternative to subjective assessment of constipation.

OBJECTIVE: The global population is aging and the burden of lower urinary tract symptoms (LUTS) is expected to increase. According to the National Health Insurance Research Database, our previous studies have showed LUTS may predispose patients to cardiovascular disease. However, it is difficult to provide a personalized risk assessment in the context of "having acute coronary syndrome (ACS) and stroke." This study aimed to develop an artificial intelligence (AI)-based prediction model for patients with LUTS. MATERIAL AND METHODS: We retrospectively reviewed the electronic medical records of 1799 patients with LUTS at Chi Mei Medical Center between January 1, 2001 and December, 31, 2018. Features with >10 cases and high correlations with outcomes were imported into six machine learning algorithms. The study outcomes included ACS and stroke. Model performances was evaluated using the area under the receiver operating characteristic curve (AUC). The model with the highest AUC was used to implement the clinical risk prediction application. RESULTS: Age, systemic blood pressure, diastolic blood pressure, creatinine, glycated hemoglobin, hypertension, diabetes mellitus and hyperlipidemia were the most relevant features that affect the outcomes. Based on the AUC, our optimal model was built using multilayer perception (AUC = 0.803) to predict ACS and stroke events within 3 years. CONCLUSION: We successfully built an AI-based prediction system that can be used as a prediction model to achieve time-saving, precise, personalized risk evaluation; it can also be used to offer warning, enhance patient adherence, early intervention and better health care outcomes.

PURPOSE: The study aimed to determine the typical clearance and volume of distribution values of tamsulosin in patients with benign prostatic hyperplasia (BPH), and to identify factors with a measurable impact on the drug's elimination. METHODS: This open-label, single-arm population pharmacokinetic study involved 65 adult men with BPH who had been on tamsulosin therapy for at least seven days. The steady-state serum concentrations of tamsulosin were measured using liquid chromatography-tandem quadrupole mass spectrometry. Population pharmacokinetic parameters, their variability, and influencing factors were estimated based on a two-compartment pharmacokinetic model using NONMEM software. RESULTS: The estimated tamsulosin clearance in BPH patients was 0.719 L/h, and the steady-state volume of distribution was 32 L. Neither renal nor liver function parameters had a statistically significant effect on tamsulosin clearance. However, a positive correlation was observed between hemoglobin levels and tamsulosin clearance in the BPH patient cohort. CONCLUSION: Our investigation reveals significant associations between tamsulosin pharmacokinetics and specific characteristics of patients with lower urinary tract symptoms (LUTS) due to BPH. The study highlights that tamsulosin clearance is associated with hemoglobin levels in patients with LUTS/BPH. This study underscores the importance of considering patient-specific factors when managing BPH treatment with tamsulosin, emphasizing associations rather than causative relationships.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a condition commonly seen among men aged over 40, significantly affecting their quality of life and typically accompanied by lower urinary tract symptoms (LUTS). Acupuncture presents a potentially effective treatment option; however, the exact effects remain uncertain. Therefore, we design this multicentre randomised trial to evaluate the efficacy and safety of electroacupuncture (EA) for relieving LUTS in men with BPH. METHODS AND ANALYSIS: A two-arm, sham-controlled, subject-blinded and assessor-blinded trial will be conducted in 11 hospitals in China to compare EA with sham electroacupuncture (SA) in treating moderate to severe LUTS of BPH among men aged 40-80. A total of 306 eligible male patients will be recruited and assigned at a 1:1 ratio to receive either EA or SA for 24 sessions over a succession of 8 weeks, with 24 weeks of follow-up. The primary outcome will be the proportions of participants with at least 30% reduction in the International Prostate Symptom Score total score from baseline at weeks 8 and 20. All statistical analyses will be conducted in accordance with the intention-to-treat principle, and a two-tailed p value less than 0.05 will be considered statistically significant. ETHICS AND DISSEMINATION: The trial has been approved by the institutional review board of Guang'anmen Hospital (2022-203-KY), as well as other recruitment centres. Each participant will receive the detailed information of the trial, and sign the written informed consent. The results of the trial are expected to be published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT05585450.

BACKGROUND: Benign prostatic hyperplasia (BPH) commonly causes lower urinary tract symptoms (LUTS) in men. Holmium (HoLEP) and thulium (ThuLEP) laser enucleation are established techniques for BPH treatment. Thulium fiber laser (TFL) for prostate enucleation (ThuFLEP) shows promising outcomes. METHODS: A prospective randomized multicenter study was conducted. Patients with BPH and LUTS unresponsive to medical therapy were enrolled. Preoperative, surgical, perioperative and postoperative data were recorded with follow-up at 3 and 6 months. The primary outcome was functional improvement, and the secondary outcome was safety in terms of complications. RESULTS: Two hundred patients were included (HoLEP 100, ThuFLEP 100). No significant baseline difference was found between groups. At 3 and 6 months we found statistically significant improvements from baseline for both HoLEP and ThuFLEP in efficacy: International Prostatic Symptoms Score (IPSS), IPSS-Quality of Life (QoL), maximum urinary flow rate (Q

Benign prostate hyperplasia (BPH) affects a large number of men and can be treated with behavioral, medical, or surgical treatments. The newest addition to medical therapy is ß3-agonists for overactive lower urinary tract symptoms. Multiple new surgical treatments have become available in the past decade, including several clinic-based minimally invasive surgical techniques (eg, UroLift, Rezum, Optilume BPH), OR treatments (eg, Aquablation, single port robotics), and prostate artery embolization. The growth of options allows providers to better tailor BPH treatment to the specific disease factors and patient preferences.

BACKGROUND: This study aims to determine the effect of pelvic floor function exercise on the improvement of lower urinary tract symptoms in patients with uterine fibroid surgery. METHODS: The clinical data of 188 patients who underwent uterine fibroid surgery in our hospital from February 2020 to December 2022 were retrospectively analysed. The patients were divided into a control group and an observation group according to the nursing methods recorded in the data. The observation group received targeted nursing combined with pelvic floor function exercise based on routine intervention. General demographic data, disease and surgery-related characteristics of the patients were collected. Propensity score matching was used to balance the baseline data of the two groups. Lower urinary tract symptoms, pelvic floor function, pelvic floor muscle strength and quality of life were compared between the two groups after matching. RESULTS: A total of 130 patients were included in the two groups, and their baseline data were not statistically significant. At 3 months after the operation, the total incidence of lower urinary tract symptoms in the observation group (10.77%) was lower than that in the control group (30.77%, p < 0.05). Before the intervention, the pelvic floor function, pelvic floor muscle strength and quality of life scores of the two groups were basically the same (p > 0.05). At 3 months after the operation, the pelvic floor function score of the observation group was lower than that of the control group, but the pelvic floor muscle strength index and quality of life score of the observation group were higher than those of the control group (p < 0.05). CONCLUSIONS: Targeted nursing combined with pelvic floor function exercise for patients with uterine fibroids surgery can prevent the occurrence of lower urinary tract symptoms and improve the pelvic floor function, pelvic floor muscle strength and quality of life of patients and is thus worthy of promotion.

OBJECTIVE: This study aimed to analyse the effect of pelvic floor function exercises based on the enhanced recovery after surgery (ERAS) concept on lower urinary tract symptoms after radical hysterectomy for cervical cancer. METHODS: The retrospective study was conducted using clinical data of patients admitted to our hospital from January 2021 to December 2022 and underwent radical hysterectomy for cervical cancer. In accordance with the nursing method, the patients were divided into the routine group (conventional care) and the ERAS pelvic floor function exercise group, for which ERAS concept-based pelvic floor function exercises were carried out on the basis of the former group. The confounders between the two groups were matched by propensity score, and the scores of urination, pelvic floor muscle strength, lower urinary tract symptoms and quality of life (QoL) were compared between the two groups after matching. RESULTS: A total of 180 patients were included in the study, of whom 60 patients were identified after propensity score matching, consisting of 30 patients each in the ERAS and routine groups. The baseline characteristics of the two groups were balanced, and the difference was not statistically significant (p > 0.05). Compared with the routine group, the observation group showed significantly shorter first spontaneous urination time, greater first urination volume (p < 0.05), better pelvic floor muscle strength, considerably lower urinary tract symptoms and better QoL at discharge and 3 months after discharge (p < 0.05). CONCLUSIONS: Pelvic floor function exercises based on the ERAS concept can relieve lower urinary tract symptoms, accelerate urination and improve pelvic floor muscle strength and QoL after radical hysterectomy for cervical cancer.

INTRODUCTION: Prostate cancer is the second most common malignancy in men worldwide. Genomic VPAC receptors are expressed on malignant prostate cancer cells and can be targeted and imaged optically by a peptide labeled fluorophore. The objective of our study was to assess the feasibility of detecting cancer of the prostate using a voided urine sample. MATERIALS AND METHODS: Patients ≥ 40 years old, with lower urinary tract symptoms and serum PSA > 4 ng/mL formed the study group. The first 50 mL of voided urine sample was collected and processed. The cells that were shed in the voided urine were fixed and stained with a peptide TP4303 and incubated. The slide was then stained with DAPI which binds with the DNA in the nucleus. All patients underwent a standard 12-core TRUS-guided prostate biopsy. RESULTS: A total of 318 patients were included in the study, of these 158 were histologically confirmed cancers. Voided urine samples were positive for VPAC receptors in 154 (97.46%) of these. The remaining 160 patients had no cancer on the HPR examination and none of these patients were positive for VPAC receptors. CONCLUSIONS: This study validates our belief that patients with prostate cancer shed malignant cells in the urine that can be identified by targeting the VPAC receptors. If these results are further validated by multicentric studies, then this could form the basis for indications for a preliminary prostate biopsy in patients with elevated serum PSA but normal digital examination or in patients needing a repeat biopsy.

PROBLEM: The aim of this study was to evaluate the change in LUTS in patients treated with RALP and to assess factors that may predict an improvement of LUTS. MATERIALS AND METHOD: In our institutional prospective research registry, 1935 patients operated in the period between 2009 and 2021 with complete baseline- and 12-month EPIC-26 questionnaire were eligible for the study. Also SF-12 data estimating general quality of life (QoL) were analyzed. A LUTS summary score was constructed from the two questions concerning voiding stream/residual and frequency, and transformed linearly to a 0-100 scale with higher scores representing less symptoms A change of 6 points or more were considered Meaningful Clinical Differences (MCD). Two summary scores were calculated from the SF-12 - a mental component score (MCS-12) and a physical component score (PCS-12). Multivariate regression was used to estimate covariates associated with postoperative MCD, MCS-12 and PCS-12. RESULTS: Mean change of LUTS-score showed an increase of 10 points 12-months post-RALP. 52% of patients achieved MCD. In multivariate logistic regression, preoperative LUTS was statistically significant associated with MCD. Reduction of LUTS was associated improved mean score of MCS-12 and PCS-12. DISCUSSION AND CONCLUSION: Along with information about risk for urinary incontinence after RALP, patients with LUTS at baseline must be informed that these symptoms may be reduced after RALP. In our study, this LUTS reduction was associated with better general QoL.

BACKGROUND: The International Prostate Symptom Score (IPSS) is a patient-reported measurement to assess the lower urinary tract symptoms of bladder outlet obstruction. Bladder outlet obstruction induces molecular and morphological alterations in the urothelium, suburothelium, detrusor smooth muscle cells, detrusor extracellular matrix, and nerves. We sought to analyze MRI-based radiomics features of the urinary bladder wall and their association with IPSS. METHOD: In this retrospective study, 87 patients who had pelvic MRI scans were identified. A biomarker discovery approach based on the optimal biomarker (OBM) method was used to extract features of the bladder wall from MR images, including morphological, intensity-based, and texture-based features, along with clinical variables. Mathematical models were created using subsets of features and evaluated based on their ability to discriminate between low and moderate-to-severe IPSS (less than 8 vs. equal to or greater than 8). RESULTS: Of the 7,666 features per patient, four highest-ranking optimal features were derived (all texture-based features), which provided a classification accuracy of 0.80 with a sensitivity, specificity, and area under the receiver operating characteristic curve of 0.81, 0.81, and 0.87, respectively. CONCLUSION: A highly independent set of urinary bladder wall features derived from MRI scans were able to discriminate between patients with low vs. moderate-to-severe IPSS with accuracy of 80%. Such differences in MRI-based properties of the bladder wall in patients with varying IPSS's might reflect differences in underlying molecular and morphological alterations that occur in the setting of chronic bladder outlet obstruction.

BACKGROUND: There are a variety of medical and surgical treatment options available today for the management of lower urinary tract symptoms (LUTS) secondary to bladder outlet obstruction due to benign prostatic hyperplasia (BPH). OBJECTIVE: The aim of this paper is to highlight the various treatment options available for the management of bladder outlet obstruction secondary to BPH and discuss the benefits and potential drawbacks of each. DISCUSSION: Lifestyle and dietary modification and medical therapies, such as an alpha-1 blocker as monotherapy, should be considered as first-line when initially counselling a patient for LUTS secondary to bladder outlet obstruction due to BPH. If bothersome LUTS persist despite medical management, or if medical management is not suitable or preferable, then surgical interventions can be considered. The mainstay of surgical intervention has traditionally been transurethral resection of the prostate (TURP); however, the treatment landscape is rapidly evolving with the development of minimally invasive procedures.

BACKGROUND: Lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) significantly impact quality of life among older men. Despite the prevalent use of the American Urological Association Symptom Index (AUA-SI) for BPH, this measure overlooks key symptoms such as pain and incontinence, underscoring the need for more comprehensive patient-reported outcome (PRO) tools. This study aims to integrate enhanced PROs into routine clinical practice to better capture the spectrum of LUTS, thereby improving clinical outcomes and patient care. METHODS: This prospective observational study will recruit men with LUTS secondary to BPH aged ≥ 50 years from urology clinics. Participants will be stratified into medical and surgical management groups, with PRO assessments scheduled at regular intervals to monitor LUTS and other health outcomes. The study will employ the LURN Symptom Index (SI)-29 alongside the traditional AUA-SI and other non-urologic PROs to evaluate a broad range of symptoms. Data on comorbidities, symptom severity, and treatment efficacy will be collected through a combination of electronic health records and PROs. Analyses will focus on the predictive power of these tools in relation to symptom trajectories and treatment responses. Aims are to: (1) integrate routine clinical tests with PRO assessment to enhance screening, diagnosis, and management of patients with BPH; (2) examine psychometric properties of the LURN SIs, including test-retest reliability and establishment of clinically meaningful differences; and (3) create care-coordination recommendations to facilitate management of persistent symptoms and common comorbidities measured by PROs. DISCUSSION: By employing comprehensive PRO measures, this study expects to refine symptom assessment and enhance treatment monitoring, potentially leading to improved personalized care strategies. The integration of these tools into clinical settings could revolutionize the management of LUTS/BPH by providing more nuanced insights into patient experiences and outcomes. The findings could have significant implications for clinical practices, potentially leading to updates in clinical guidelines and better health management strategies for men with LUTS/BPH. TRIAL REGISTRATION: This study is registered in ClinicalTrials.gov (NCT05898932).

INTRODUCTION: This study evaluated the perioperative and early postoperative outcomes of transurethral water vapour thermal therapy (WVTT) under local anaesthesia alone for benign prostatic enlargement in Chinese patients. METHODS: This retrospective review of transurethral WVTT for benign prostatic enlargement focused on 50 Chinese patients who exhibited clinical indications (acute retention of urine or symptomatic lower urinary tract symptoms due to benign prostatic enlargement) for surgical treatment between June 2020 and December 2021 in Hong Kong. Exclusion criteria included active urinary tract problems and urological malignancies. Follow-up was conducted at 3 months postoperatively. RESULTS: The median patient age was 71.5 years. The mean preoperative prostatic volume was 56.7 mL. The mean operation time was 25.1 minutes. All procedures were performed under local anaesthesia alone. The mean pain scores for transrectal ultrasound probe insertion, transperineal local anaesthesia injection, and transurethral WVTT were 2, 5, and 4, respectively. Forty-nine patients (98%) were discharged on the same day with a urethral catheter. Forty-eight patients (96%) successfully completed a trial without catheter within 3 weeks postoperatively. Five patients (10%) had unplanned hospital admission within 30 days postoperatively due to surgical complications (Clavien-Dindo grade 1). CONCLUSION: Transurethral WVTT, an advanced surgical treatment for benign prostatic enlargement, is a safe procedure that relieves lower urinary tract symptoms with minimal hospital stay. It can be performed in an office-based setting under local anaesthesia, maximising utilisation of the surgical theatre.

INTRODUCTION: Treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) has shifted over the last decades, with medical therapy becoming the primary treatment modality while surgery is being reserved mostly to patients who are not responding to medical treatment or presenting with complications from BPH. Here, we aim to to discuss the optimal timing of surgical management of LUTS/BPH. MATERIALS AND METHODS: A literature search was conducted on Pub-Med/MEDLINE database to identify reports published from January 1990 until January 2022 by combining the following MeSH terms: "Lower Urinary Tract Symptoms"; "Prostatic Hyperplasia"; "Prostatic Hyperplasia/therapy"; "Prostatic Hyperplasia/complications"; "Treatment Outcome"; "Time-to-Treatment". Evidence supporting or not early surgical treatment of BPH was examined and reported in a pros and cons form. RESULTS: The "pro early surgery" highlighted the superior efficacy and cost-effectiveness of surgery over medical treatment for BPH, as well as the possibility of worse postoperative outcomes for delayed surgical treatment. The "con early surgery" considered that medical therapy is efficient in well-selected patients and can avoid the serious risks inherent to surgical treatment of BPH including important sexual side effects. CONCLUSIONS: Clinical trials comparing the outcomes for prolonged medical therapy versus early surgical treatment could determine which approach is more beneficial in the long-term in context of the aging population. Until then, both approaches have their advantages and patients should be involved in the treatment decision.

OBJECTIVE: The aim of this study was to investigate whether urinary glycosaminoglycans (GAG) levels reflect clinical status in men with lower urinary tract symptoms and if they could be used as a marker in management of overactive bladder (OAB). METHODS: A total of 34 patients were recruited who were admitted with LUTS and diagnosed as having clinically bladder outlet obstruction (BOO) due to prostate enlargement. These newly diagnosed, never treated patients underwent routine investigation, consisting of history, physical examination, PSA, ultrasound, uroflowmetry, assessment of symptoms scored by both International Prostate Symptom Score (IPSS) and Marmara- Overactive Bladder Questionnaire (M-OBQ). The patients were divided into two groups as those with an initial M-OBQ score < 12 (group 1) and ≥ 13 (group 2). Alfa blocker was initiated in eligible patients. Further evaluations included prostate volume measurement, pre- and post-treatment urinary GAG levels, IPSS and M-QAOB values and maximum urine flow rate (Qmax). RESULTS: Before treatment, urinary GAG level was 21.5 mg/gCr (6.1-45.5) in Group 1, and 23.35 mg/gCr (15.6-32.6) in Group 2 (p =0.845). After the treatment, the GAG level in Group 1 and Group 2 were found to be 19.8 mg/gCr (7.4-70.5) and 18 (7.6- 41.7), respectively (p = 0.511). No difference in GAG levels was found in subgroup analysis for patients with or without OAB. CONCLUSIONS: In recent years, there have been many studies investigating the relationship between LUTS and urinary markers. However, in our prospective study, no relationship was found between pre- and post- treatment urinary GAG levels in patients with LUTS with or without OAB.

PURPOSE: Our objective was to investigate structural changes in brain white matter tracts using diffusion tensor imaging (DTI) in patients with overactive bladder (OAB). MATERIALS AND METHODS: Treatment-seeking OAB patients and matched controls enrolled in the cross-sectional case-control LURN (Symptoms of Lower Urinary Tract Dysfunction Research Network) Neuroimaging Study received a brain DTI scan. Microstructural integrity of brain white matter was assessed using fractional anisotropy (FA) and mean diffusivity. OAB and urgency urinary incontinence (UUI) symptoms were assessed using the OAB Questionnaire Short-Form and International Consultation on Incontinence Questionnaire-Urinary Incontinence. The Lower Urinary Tract Symptoms Tool UUI questions and responses were correlated with FA values. RESULTS: Among 221 participants with evaluable DTI data, 146 had OAB (66 urinary urgency-only without UUI, 80 with UUI); 75 were controls. Compared with controls, participants with OAB showed decreased FA and increased mean diffusivity, representing greater microstructural abnormalities of brain white matter tracts among OAB participants. These abnormalities occurred in the corpus callosum, bilateral anterior thalamic radiation and superior longitudinal fasciculus tracts, and bilateral insula and parahippocampal region. Among participants with OAB, higher OAB Questionnaire Short-Form scores were associated with decreased FA in the left inferior fronto-occipital fasciculus, P < .0001. DTI differences between OAB and controls were driven by the urinary urgency-only (OAB-dry) but not the UUI (OAB-wet) subgroup. CONCLUSIONS: Abnormalities in microstructural integrity in specific brain white matter tracts were more frequent in OAB patients. More severe OAB symptoms were correlated with greater degree of microstructural abnormalities in brain white matter tracts in patients with OAB. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02485808.

INTRODUCTION: To report ejaculatory and urinary results in patients who underwent holmium laser enucleation of the prostate (HoLEP) with selective laser enucleation of the median lobe (MLHoLEP). METHODS: Patients with lower urinary tract symptoms (LUTS)/benign prostatic obstruction (BPO) who underwent MLHoLEP to preserve ejaculatory function in a single center were retrospectively identified. Urinary function was assessed using International Prostate Score Symptom (IPSS), IPSS-Quality of Life index (IPSS-QoL), peak urinary flow (Qmax) and postvoid residual (PVR). Erectile function was assessed using International Index of Erectile Function (IIEF-5). In patients with preoperative antegrade ejaculation, retrograde ejaculation was routinely screened at each follow-up visit. Sexual and urinary functions at 3 and 12 months were compared with baseline values. RESULTS: A total of 55 patients met our inclusion criteria. A significant improvement in the IPSS, IPSS-QoL, PVR and Qmax was found at 3 and 12 months, compared with baseline (all P<0.05). Eight patients (14.5%) required surgical reintervention due to persistant LUTS/BPO. No significant changes in the erectile function were found at 3 (P=0.3) and 12 months (P>0.9). In patients with preoperative antegrade ejaculation (n=32), only four cases of de novo retrograde ejaculation were recorded postoperatively. CONCLUSION: MLHoLEP represents a new alternative for men with LUTS/BPO who wish to preserve their ejaculatory function. Patients should be aware that improvement in urinary function may be inferior to the traditional technique, with a higher reintervention rate due to persistent LUTS. LEVEL OF EVIDENCE: Grade 4.
