Enhanced Clinical Decisions for Management of Benign Prostatic Hyperplasia Using Patient-Reported Outcomes

The goal of this project is to use newly developed patient-reported outcomes to improve the clinical care of patients with benign prostatic hyperplasia. The use of new patient-centered tools will improve evaluation and clinical decision-making by including symptoms not commonly measured in men, such as urinary incontinence, and allow for more frequent assessment of lower urinary tract symptoms through remote surveillance. Through the use of care-coordination checklists, clinicians can be more responsive to post-treatment symptom changes, resulting in reduced bother from lower urinary tract symptoms and higher quality of life in patients with benign prostatic hyperplasia.

Ejaculation-Preserving Versus Conventional Dual Wavelength Diode Laser Vaporization of the Prostate

Surgery to relieve urinary blockage caused by an enlarged prostate works well, but most men lose antegrade ejaculation afterwards, because semen passes backwards into the bladder instead of forwards. For sexually active men this is an important concern and a common reason for delaying or refusing surgery. This study compared two ways of performing the same operation, laser vaporization of the prostate using a dual-wavelength diode laser. In the conventional technique, prostate tissue is removed from the bladder neck all the way to the verumontanum. In the ejaculation-preserving technique, the surgeon deliberately leaves a 10 mm rim of tissue at the bladder neck untouched, and another 10 mm of tissue just before the verumontanum untouched, while removing the blocking tissue in between. Everything else about the operation, including the laser settings, was the same. Men were assigned to one of the two techniques by a computer-generated random sequence. They were assessed before surgery and again at 7 to 14 days, 1 month, 3 months, 6 months and 12 months after surgery. The main question was how many men still had antegrade ejaculation 3 months after surgery. The study also compared urinary symptoms, urine flow rate, residual urine volume, prostate size, erectile function, complications and patient satisfaction, to find out whether preserving ejaculation costs anything in terms of relieving the urinary blockage.

BPH Global Registry

Benign prostatic hyperplasia (BPH) is one of the most common performed surgical procedures in urology. Over the past few decades there have been an increasing development of newer surgical treatment options. Additionally, the outcome parameters for BPH treatments have been standardized. While data are available for the initial pivotal studies, post-market release data are lacking. Under the umbrella of uCARE, we have started a prospective, ongoing international registry for recording demographics and outcomes for patients undergoing surgical treatments for BPH.

Iris Structural Changes With Tamsulosin vs. Silodosin in Benign Prostatic Hyperplasia Patients

Inhibition of alpha-1 adrenergic receptors by drugs such as tamsulosin and silodosin, which are prescribed for the treatment of benign prostatic hyperplasia, can lead to intraoperative floppy iris syndrome (IFIS) during cataract surgery. IFIS is a phenomenon characterized by a small, poorly dilating pupil and causes surgical difficulty. Main objective: To determine and compare changes in the anatomical structure of the iris in patients with BPH before and after treatment with tamsulosin and silodosin. Men aged 50 years and older with a definitive diagnosis of BPH who have no prior history of alpha-blocker use will be enrolled in one of the two treatment arms - tamsulosin or silodosin. Imaging will be performed using an MS-39 device (manufactured by CSO, Italy); assessments will be conducted at two time points - before the start of treatment and after three months of continuous drug use. At baseline and three months after treatment, using AS-OCT, the DMR and SMR regions and other ocular angle indices will be measured. Medication adherence will be assessed by counting the capsules used by each patient. Specific Objectives: 1. To determine changes in the dilator muscle region (DMR) under scotopic, mesopic, photopic, and post-dilation conditions from baseline to the third month in the tamsulosin \& silodosin groups and compare them. 2. To determine changes in SMR under scotopic, mesopic, photopic, and post-dilation conditions from baseline to the third month in the tamsulosin \& silodosin groups and compare them.

Pupil Size and Choroidal Thickness Changes With Tamsulosin vs. Silodosin in Benign Prostatic Hyperplasia Patients

Benign prostatic hyperplasia (BPH) is a common disease in men and is treated with alpha-blockers, particularly tamsulosin and silodosin. Studies suggest that these drugs may affect α1a receptors in the iris dilator muscle, causing structural changes in the iris and pupillary disturbances, and increasing the risk of intraoperative floppy iris syndrome (IFIS) during cataract surgery. Main objective: To compare the effect of tamsulosin and silodosin on pupil size and choroidal thickness in patients with BPH. Men aged 50 years and older with a definitive diagnosis of BPH who have no prior history of alpha-blocker use will be enrolled in one of the two treatment arms - tamsulosin or silodosin. Assessments will be conducted at two time points - before the start of treatment and after three months of continuous. * Pupillography will be performed at three standard illumination levels - scotopic 0.04 lux, mesopic 4 lux, and photopic 50 lux - with pupil diameter automatically recorded under each condition using the MS-39 device (manufactured by CSO, Italy). * Choroidal assessment will use EDI-OCT (Heidelberg) macular imaging, measuring choroidal thickness at the subfoveal position and at 500 and 1000 micron nasal and temporal points. To reduce daily fluctuations related to circadian rhythm, all imaging will be performed within a fixed window of 9-11 a.m. by a single trained operator. drug use.

After completion of radiotherapy the patient will be seen at 12 weeks

Early Electroacupuncture for Post-TURP LUTS

1\. Project Rationale Benign prostatic hyperplasia (BPH) is one of the most prevalent urological disorders among middle-aged and elderly men, and it represents a common chronic condition in the male population. Its incidence increases from 8% in men aged 31-40 years to over 80% in men aged over 80 years. With the intensification of global population aging, the prevalence of BPH and the corresponding burden on global public healthcare systems have been increasing continuously. BPH not only impairs patients' micturition function and reduces their quality of life, but also may lead to multiple complications involving the urinary system, such as urinary tract infection, bladder calculi and renal function impairment. Although the exact etiology of BPH remains incompletely elucidated, existing studies have confirmed that multiple factors including age, altered hormone levels, genetic background and lifestyle are associated with its pathogenesis. The global number of prevalent BPH cases increased from 51 million in 2000 to 94 million in 2019, representing a 70.5% growth in global prevalence during this period. Driven by population aging, changes in lifestyle and the popularization of screening methods such as prostate-specific antigen (PSA) detection, the number of prevalent BPH cases in China increased from 10.2 million in 2000 to 20.3 million in 2019, with a 99.0% growth in prevalence over the period, which exceeds the global average growth rate. Data from the 7th National Population Census of China in 2021 shows that the population aged 60 years and above in China reaches approximately 264 million, accounting for 18.70% of the total population, which is 5.44 percentage points higher than the data from the 6th National Population Census in 2010, and this figure is projected to exceed 400 million by 2050. The intensification of population aging and the corresponding growth in BPH prevalence indicate that BPH has evolved from a common urological disease to a major public health issue that poses a substantial threat to the health of Chinese men. Transurethral resection of the prostate (TURP) and holmium laser enucleation of the prostate (HoLEP) are routine surgical interventions for BPH, which can effectively reduce prostate volume and improve micturition function in patients. However, persistent lower urinary tract symptoms (LUTS) such as urinary frequency, urgency and dysuria after surgery still negatively affect patients' quality of life. Approximately 30% of patients with pre-operative urological symptoms experience persistent symptoms after surgery. Due to symptom persistence, up to 27% of male patients receive pharmacological intervention for LUTS after TURP. This poses a great challenge to patients' physical and mental health, and effective intervention strategies are urgently needed. Currently, the management of post-TURP LUTS mainly relies on conservative interventions such as Pelvic Floor Muscle Training (PFMT) and pharmacological therapy. However, these interventions are typically initiated after urinary catheter removal, which cannot meet the demand for immediate urinary continence after catheter withdrawal. In addition, the therapeutic effect of PFMT requires long-term persistence, which generally leads to poor patient adherence, and the most critical limitation is the lagged intervention timing. Similar issues including delayed intervention and unsatisfactory efficacy also exist in pharmacological therapy. Currently, medications for LUTS secondary to BPH include α-adrenergic receptor blockers, 5-α reductase inhibitors, anticholinergics, β-3 adrenergic receptor agonists and phytotherapy. These agents are routinely used for the management of BPH and BPH-related LUTS, and are widely applied to alleviate persistent or new-onset LUTS after BPH surgery. Although these drugs are generally adopted as standard interventions for post-BPH surgery LUTS, multiple studies have demonstrated that there are no significant differences in objective indicators including symptom score, quality of life index and post-void residual volume between patients receiving these medications after BPH surgery and patients receiving placebo. Currently, there is still a lack of effective and widely accepted intervention regimens for LUTS after BPH surgery. Against the background that existing treatment modalities cannot meet clinical demand, this study proposes early post-operative electroacupuncture as an innovative and scientifically sound intervention strategy. Acupuncture is not merely a simple "alternative therapy", but an effective "non-invasive peripheral neuromodulation technique" validated by modern medical research. Existing studies have shown that acupuncture exerts a certain therapeutic effect on relieving BPH-related LUTS. For example, in a study conducted by Chen Chao et al., clear conclusions were drawn by comparing the efficacy of acupuncture and α-adrenergic receptor blockers in the treatment of 64 patients with BP

The Application of Multimodal Artificial Intelligence Systems in Prostate Cancer Diagnosis and Prognosis Analysis

Prostate-specific antigen (PSA) testing has limited specificity for prostate cancer diagnosis, leading to a high rate of unnecessary biopsies. This multi-center study aims to develop and validate a non-invasive, multi-modal artificial intelligence model that combines cell-free DNA (cfDNA) profiles with multi-parametric MRI (mpMRI). The primary goal is to improve the accuracy of prostate cancer detection and risk stratification, particularly for men with PSA levels in the 4-10 ng/mL "gray zone," thereby providing a robust tool to guide clinical decision-making and reduce avoidable invasive procedures.

Thulium Laser Enucleation With Bladder Neck Incision for Small-Volume Benign Prostatic Hyperplasia

This study will evaluate the safety and effectiveness of different surgical treatments for men with small-volume benign prostatic hyperplasia (BPH). Men with small-volume BPH may still have bothersome lower urinary tract symptoms and bladder outlet obstruction, and the best surgical treatment for this group remains uncertain. In this multicentre, randomized, single-blind, four-arm controlled trial, 932 eligible men aged 40 to 80 years will be assigned in a 1:1:1:1 ratio to one of four groups: thulium laser enucleation of the prostate combined with bladder neck incision, thulium laser enucleation of the prostate alone, transurethral resection of the prostate (TURP), or transurethral incision of the prostate (TUIP). The main goal of the study is to compare the incidence of bladder neck contracture at 6 months after surgery. Secondary outcomes include safety outcomes and changes in urinary symptoms, urinary flow rate, pain score, and symptom response at 3 and 6 months after surgery. Exploratory outcomes include changes in post-void residual urine volume and sexual function scores. Additional exploratory long-term outcomes will also be assessed at 12 months after surgery.

Effect of Different Dosing Regimens of Tadalafil or Tamsulosin Combined With 5α-Reductase Inhibitors on Urinary and Sexual Outcomes in Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH) is a common condition among aging men that causes lower urinary tract symptoms (LUTS) and may negatively affect sexual function. This randomized single-blind controlled clinical trial compares the efficacy, safety, and sexual outcomes of different dosing regimens of tadalafil or tamsulosin combined with 5-alpha reductase inhibitors (5ARIs) in men with BPH and enlarged prostate volume. A total of 240 participants were randomly assigned to six treatment groups and followed for 12 weeks. Changes in urinary symptoms, erectile function, ejaculatory function, prostate volume, prostate-specific antigen (PSA), urinary flow rate, post-void residual volume, and adverse events were evaluated to determine the optimal combination regimen.

MRI-DTI Assessment of Urethral Internal Sphincter Ring and Prostate Base Morphology

This is a single-center, observational imaging study designed to evaluate the in vivo morphology of the male urethral internal sphincter ring using magnetic resonance diffusion tensor imaging (MRI-DTI) fiber tracking and to investigate its relationship with prostate base morphology. Male participants undergoing clinically indicated pelvic, seminal vesicle, or prostate-related MRI-DTI examinations will be included. The study population may include patients with benign prostatic enlargement, younger men undergoing MRI for suspected cryptorchidism or suspected seminal vesiculitis, and patients with prostate cancer scheduled to receive androgen deprivation therapy (ADT). All participants will undergo T2-weighted imaging and DTI. T2WI-DTI image registration, dual-region-of-interest fiber tracking, and three-dimensional reconstruction will be used to visualize ring-like muscle fiber structures in the bladder neck, prostate base, and proximal urethral region. The cross-sectional imaging cohort will be used to assess the associations between prostate-side morphological parameters, including prostate volume, prostate base diameter or area, and intravesical prostatic protrusion, and sphincter-ring parameters, including ring inner diameter and ring area. The ADT paired cohort will undergo MRI-DTI before treatment and during follow-up after ADT to evaluate whether reduction in prostate volume and prostate base morphology is accompanied by corresponding changes in the urethral internal sphincter ring. This study will not alter the participants' existing clinical diagnostic or treatment pathways. Imaging data will be analyzed using standardized post-processing and quantitative measurement procedures. The results may provide in vivo imaging evidence for age- and prostate-related displacement and morphological remodeling of the male urethral internal sphincter and may inform future surgical strategies for identifying, preserving, or reconstructing proximal urinary continence-related structures.

A Study to Track the Safety of Vesomni in Men in South Korea Treated in Routine Clinical Practice for the Urinary Symptoms of Benign Prostatic Hyperplasia (Enlarged Prostate)

Benign prostatic hyperplasia (BPH), also known as an enlarged prostate, happens more often in men as they age. This condition causes a sudden need to pass urine, which is hard to control. Men with an enlarged prostate may need to pass urine many times during the day and night which can affect their wellbeing. There are treatments available, like tamsulosin but they don't work well in some men and can cause further health problems. Vesomni is approved in South Korea to treat urinary symptoms in men with an enlarged prostate, when treatment with tamsulosin doesn't work well enough. This study will track the safety of Vesomni given to men in South Korea who have moderate to severe symptoms from an enlarged prostate, who have previously been treated with tamsulosin and found it didn't work well. The safety of Vesomni is tracked by mainly collecting information from their medical records. The sponsor will ask for extra information to be collected, and if any health problems were caused by Vesomni. In this study, researchers want to learn about the safety of Vesomni and how well it controls symptoms in men with an enlarged prostate. The men's own doctor decides on treatment, as part of routine clinical practice, not the sponsor (Astellas). This study is about collecting information only. Most information about the safety and control of symptoms will be collected from medical records. The sponsor will also ask for extra information to be collected. All information will be collected for up to 24 weeks after the men start treatment with Vesomni.

Selective Median Lobe Surgery Outcomes Study

This prospective multicenter observational cohort study will evaluate clinical outcomes after selective median lobe transurethral surgery for benign prostatic obstruction. Eligible men with lower urinary tract symptoms or urinary retention who are scheduled for selective median lobe-only TURP, HoLEP, or anatomical endoscopic enucleation as part of routine clinical care will be enrolled and followed after surgery. The study will collect preoperative clinical data, symptom scores, uroflowmetry, postvoid residual volume, prostate volume, intravesical prostatic protrusion measurements, cystoscopic anatomical findings, intraoperative variables, and postoperative outcomes. The primary outcome is composite clinical failure at 12 months. The main aim is to identify practical preoperative urology-based anatomical and functional predictors of clinical failure after selective median lobe surgery and to develop an exploratory prediction model that may help improve patient selection in future practice.

Preoperative Anxiety and Surgical Fear in Holmium Laser Enucleation of the Prostate and Transurethral Resection of the Prostate Patients With Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH) is a common condition in older men and may cause bothersome lower urinary tract symptoms that can negatively affect quality of life. Surgical treatment with Holmium Laser Enucleation of the Prostate (HoLEP) or Transurethral Resection of the Prostate (TURP) is often recommended when medical therapy is insufficient. This prospective observational study aims to evaluate whether preoperative anxiety, depression, and surgical fear influence postoperative functional outcomes, urinary continence, erectile function, and patient satisfaction in patients undergoing HoLEP or TURP for BPH. Participants will complete validated psychological and functional questionnaires before surgery and during postoperative follow-up visits at 1 and 3 months. The study will also assess changes in psychological status after surgery and compare outcomes between HoLEP and TURP patients. The findings may help improve preoperative patient counseling and identify patients who could benefit from additional psychological support before surgery.
