Association Between Qmax/eGFR Ratio and LUTS Severity in Men Over 40

This study will look at how well a measure called the Qmax/eGFR ratio is related to the severity of urination problems in men over the age of 40. Qmax is a test that shows how fast a person can urinate, and eGFR is a number that reflects kidney function. Men who have urinary symptoms will be asked to do a urine flow test, a blood test, and fill out a questionnaire about their symptoms and quality of life. We will study if there is a link between the Qmax/eGFR ratio and how severe their symptoms are. The results may help doctors better understand how kidney and urinary function are related in men with these problems.

Uroflowmetry Curve Types and IPSS in Men With LUTS

This prospective observational study aims to evaluate the relationship between different uroflowmetry curve types and International Prostate Symptom Score (IPSS) domains in men presenting with lower urinary tract symptoms (LUTS). Participants will undergo routine clinical evaluations including uroflowmetry, laboratory assessments, and completion of the IPSS questionnaire. Each participant will be classified into one of five predefined uroflowmetry curve types (normal/bell-shaped, plateau, staccato, intermittent, or tower-like). The IPSS will be analyzed both as a total score and as two subdomains: storage and voiding symptoms. Additional data such as age, comorbidities, medication use, prostate volume, eGFR, and QoL score will also be recorded to assess potential correlations and predictive factors for symptom severity. The goal of this study is to better understand how objective urodynamic findings correlate with patient-reported symptoms and to inform clinical decision-making in men with LUTS.

Uroflowmetry and IPSS Factors Influencing Surgical Decision

This study aims to identify which symptoms or test findings lead men with lower urinary tract symptoms (LUTS) to consider surgical treatment. Male patients who visit the outpatient clinic for LUTS will be asked whether they would consider surgery in the future if their symptoms persist. Along with this, symptom severity scores (IPSS), quality of life scores, and uroflowmetry measurements such as maximum flow rate (Qmax) and post-void residual volume (PVR) will be collected. The goal is to determine which factors are most strongly associated with a desire for surgery. This is an observational, non-interventional study.

Treatment Outcomes Under a Standardized Treatment Protocol in Patients Suffered Substance Abuse Related Voiding Dysfunction

With the increase of substance abuse over the world, substance abuse e.g. ketamine and methamphetamine related voiding dysfunction is becoming an important medical problem. However, while the clinical manifestation of the condition is becoming better defined, the underlying pathophysiology is still poorly understood. Moreover, majority of the current treatment is just based on the experience on some small case series and there is no treatment data for larger patient sample or standard recommended treatment in the literature. In order to improve the management of this condition, investigators have formulated a treatment protocol based on the current literatures on the management of voiding dysfunction and also a similar condition, interstitial cystitis / painful-bladder syndrome (IC/PBS). The protocol basically consists of the following modalities: * Basic information and education on the condition, principle of treatment and psychosocial support. * First line treatment will include a course of oral anti-inflammatory drugs (for the control of the inflammation process and pain) and anticholinergic agents (for the irritative urinary symptoms). * If these simple oral medication are found to be not effective, then further treatment will include other oral medications, such as amitriptyline and gabapentin, and some drugs that directly applied into the bladder cavity (hyaluronate) or bladder muscle (botulinum toxin). * For those patients with intractable symptoms and failed all the above treatments, surgical treatment (hydrodistension, augmentation cystoplasty) will be discussed. The purpose of this research is to assess the effectiveness of the above treatment protocol in the management of substance induced voiding dysfunction and also assess any possible adverse events related to the usage of the drugs.

HOme PElvic Floor Improvement Trainer Trial

This study will gauge the efficacy of a home biofeedback treatment device for pelvic floor dysfunction/voiding dysfunction and pelvic pain. Investigators will test the utility of this device as a treatment alternative and/or temporary treatment for a patient's symptoms prior to or perhaps in lieu of their physical therapy appointment.

The Role of Timed Awakening in Treatment of Enuresis

The goal of this clinical trial is to evaluate the effectiveness of nightly timed awakening in the treatment of nocturnal enuresis in children aged 6-17. The main questions it aims to: * Determine feasibility of nightly timed awakenings * Determine the role, if any, of comorbidities on resolution of enuresis * Determine incidence of daytime accidents * Obtain patient and parental satisfaction scores Researchers will compare a control group to treatment groups to see if there is any impact on nocturnal enuresis. Participants will be woken up by parents in the middle of the night to use the restroom. In addition, participants will receive 30 minute psychotherapy sessions using telehealth.

Efficacy of Alpha-blockers (Tamsulosin) in the Treatment of Symptomatic Dysuria in Multiple Sclerosis in Women

Multiple sclerosis (MS) is the leading non-traumatic cause of severe acquired disability in young people. The disease is defined by relapses, which can affect all neurological functions depending on the location of the new inflammatory lesion(s). The disease can thus manifest itself through bladder and bowel disorders (BWS), which affect approximately 80% of MS patients in all stages. Lower urinary tract dysfunction has a significant negative impact on the quality of life of patients and places a significant burden on the healthcare system in terms of resource allocation. In addition, there is a risk of long-term chronic renal failure, an infectious risk (recurrent cystitis and/or pyelonephritis, sometimes life-threatening) and a lithiasis risk. The most frequently observed urinary symptoms are: urinary frequency, urgency with or without urinary incontinence, dysuria and chronic retention of urine. These disorders most often combine bladder hyperactivity and dysuria. This dysuria may be responsible for recurrent urinary tract infections, lithiasis, alteration of renal function. The only therapeutic class currently used to treat dysuria in MS is alpha-blockers. Tamsulosin, alfusozin and doxazosin induce relaxation of the urethral smooth sphincter and prostatic urethral muscle fibers, facilitating the removal of subvesical obstruction and bladder emptying. The study investigators hypothesize that treatment with tamsulosin 0.4 mg daily in adult MS patients with dysuria will result in symptom improvement as assessed by the International Prostate Symptom Score (IPSS) and Urinary Symptom Profile (USP) scores, a decrease in post-void residual, and an improvement in urine flow and quality of life.
