  Hann-Chorng KuoTaiwan Moderator ACU Lecture: Videourodynamic Study for Precision Diagnosis and Management of Lower Urinary Tract DysfunctionVideourodynamic Study in the Precision Diagnosis and Management of Lower Urinary Tract Dysfunctions Hann-Chorng Kuo, M.D. Department of Urology, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Tzu Chi University, Hualien, Taiwan As a urologist, we are dealing with patients with lower urinary tract symptoms everyday. We did transurethral resection of the prostate (TURP) for elderly men with bothersome lower urinary tract symptoms (LUTS). We put a suburethral sling for women with stress urinary incontinence (SUI). We prescribed alpha-blocker for those who had difficulty in urination. We add antimuscarinics for patients with urgency urinary incontinence. Our seniors always told us these treatments are effective in treating patients with LUTS. However, patients still had LUTS after TURP, women still complained of urgency and dysuria after anti-incontinence surgery. Medication based on storage or emptying LUTS do not work all the time. Why? Because symptoms are not reliable, a large prostate does not indicate bladder outlet obstruction (BOO), and SUI is not solely a result of urethral incompetence. Therefore, in diagnosis and management of LUTS, we need precision medicine to direct an accurate pathophysiology of LUTS, and to guide an appropriate management based on the bladder and bladder outlet dysfunction. When we encounter patients who have LUTS refractory to the treatment based on our initial diagnosis, when we are treating patients who have complicated storage and emptying LUTS, when we are not sure patients could benefit from the invasive procedures for their LUTS, or patients who had both lower and upper urinary tract dysfunctions, videourodynamic study (VUDS) is an essential investigation for diagnosis and management of LUTS. In additional to benign prostate hyperplasia (BPH) and BOO, male patients with emptying LUTS might result from detrusor underactivity (DU), bladder neck dysfunction (BND), urethral sphincter dysfunction, or a hypersensitive bladder, which is not related with the prostate. Patients with BPH and LUTS might have latent neurogenic lesion, such as minor stroke, Parkinson's disease, or early dementia, causing LUTS. TURP without known the neurological disease might exacerbate LUTS after surgery. Mixed SUI comprises intrinsic sphincter deficiency (ISD) and detrusor overactivity (DO). The overactive bladder (OAB) symptoms may also result from an incompetent bladder outlet. Without comprehensive VUDS, we might cure the SUI, but OAB remains after placing a mid-urethral sling. Bladder pain is the cardinal symptoms of interstitial cystitis. However, bladder pain perceived by the patient might also originate from BOO or pelvic floor fascitis. VUDS can help in discrimination. DU and low compliant bladder and ISD could result in complicated storage and emptying LUTS. Large post-void residual (PVR) should alert us to investigate whether it is originated from low compliance or ISD. Dysfunctional voiding (DV) and BND in women with emptying LUTS. OAB symptoms are not always coming from the DO. BOO such as BND, DV, or urethral stricture might exist in men and women without voiding symptoms. Urinary difficulty in women is usually a result from low detrusor contractility, due to DU, or through inhibitory effect from a poorly relaxed pelvic floor or urethral sphincter. A simple bladder neck incision can effectively restore spontaneous voiding in men or women with dysuria due to DU or BND. However, a tight BN is necessary to predict a successful treatment outcome. Patients with central nervous system (CNS) disorders or spinal cord injury usually have complicated LUTD, including DO, BND, DV, detrusor sphincter dyssynergia (DSD), and vesicoureteral reflux (VUR). Management of LUTS in CNS disorders or SCI patients should know the current bladder and bladder outlet dysfunctions. Pediatric incontinence, children with myelomeningocele, DV, or recurrent urinary tract infection are complicated and need precision diagnosis before treatment. Especially when surgery is planned. Lower urinary tract dysfunctions is a dynamic condition. The bladder and bladder outlet dysfunction might change with time. Although VUDS is considered as an invasive investigation with radiation exposure, the advantages in accurate diagnosis and guiding management outweigh these disadvantages.

  Chi Wai ManHong Kong, China Speaker UAA Honorary Member Lecture: Learning through Giving Expert Opinion, a Hong Kong Case BookLearning through giving expert opinion, a Hong Kong urology case book Dr Man, Chi Wai MBBS HK FRCS Edin FRCS Glas FCSHK FHKAM Dip Urol Lond LLB Beij Consultant Urologist, Tuen Mun Hospital In Hong Kong older urologists are often asked to give expert opinions to various parties including the Coroner and the Medical Council. The expert must give unbiased assistance to the justice system. I also try to explain that there are factors other than the urologist care to account for the outcome, and to look for possible improvements in our care. Thanks for allowing me to share with you my humble experience. The Coroner in HK has the duty to determine the cause of death. If the cause is mishap, civil or disciplinary action will follow. I need to explain why death was not preventable when that was the case. The Medical Council is the statutory body responsible for overseeing professional registration and discipline. It carries out inquiries into complaints of misconduct against doctors. Most of these were about unfavourable outcome and disregard of professional responsibilities. Medical Council actively collects evidence required for proof of medical negligence. Defence could be made by disproving damage or causation of damage. In most cases, proof of no breach of duty by focusing on standard of care is required. I need to explain in such cases that despite appropriate and proper care, an unfavourable outcome could still occur. While the Bolam principle still applies to most aspects of patient care, it is no longer the case in warning patients of risks since the Montgomery case. The most important lesson I learned was that good contemporaneous documentation in medical records is the most important line of defence for urologists.

  Rajeev KumarIndia Moderator Troubleshooting in Endoscopic Stone Surgery: How to Handle Unexpected Challenges in RIRS and ECIRSProstate Cancer Nomograms and Their Application in Asian MenNomograms help to predict outcomes in individual patients rather than whole populations and are an important part of evaluation and treatment decision making. Various nomograms have been developed in malignancies to predict and prognosticate clinical outcomes such as severity of disease, overall survival, and recurrence-free survival. In prostate cancer, nomograms were developed for determining need for biopsy, disease course, need for adjuvant therapy, and outcomes. Most of these predictive nomograms were based on Caucasian populations. Prostate cancer is significantly affected by race, and Asian men have a significantly different racial and genetic susceptibility compared to Caucasians, raising the concern about the generalizability of these nomograms. There are very few studies that have evaluated the applicability and validity of the existing nomograms in in Asian men. Most have found significant differences in the performance in this population. Thus, relying on such nomograms for treating Asian men may not be appropriate and collaborative efforts are required within Asian countries to develop locally relevant nomograms.What Is Critical Appraisal?Critical appraisal is the process of systematically evaluating research studies to assess their validity, relevance, and trustworthiness. The goal is to determine whether a study’s results are credible and useful for clinical decision-making, research, or policy. This has become increasingly important as there has been a massive increase in the number of scientific journals and not all published research is of equal quality. Critical appraisal helps healthcare professionals avoid being misled by poor-quality studies, make evidence-based decisions and improve patient outcomes. The key purposes are to assess validity of the study and its results and determine applicability to the specific population. It involves assessing the study design, methodological quality, completeness of reporting, potential sources of bias and potential for misconduct. There are number of reporting guidelines that can be used for performing critical appraisal. Additionally, being aware of essential reporting standards and common problems with studies can help readers make informed decisions.Scientific Misconduct and PitfallsNo abstractExample of the “Ideal” AbstractNo Abstract
