Can ChatGPT help patients understand their andrological diseases?

We aimed to assess the reliability of Chat Generative Pre-training Transformer (ChatGPT)'s andrology information and its suitability for informing patients and medical students accurately about andrology topics. We presented a series of systematically organized frequently asked questions on andrology topics and sentences containing strong recommendations from the European Association of Urology (EAU) Guideline to ChatGPT-3.5 and 4.0 as questions. These questions encompassed Male Hypogonadism, Erectile Dysfunction and Sexual Desire Disorder, Disorders of Ejaculation, Penile Curvature and Penile Size Abnormalities, Priapism, and Male Infertility. Two expert urologists independently evaluated and assigned scores ranging from 1 to 4 to each response based on its accuracy, with the following ratings: (1) Completely true, (2) Accurate but insufficient, (3) A mixture of accurate and misleading information, and (4) Completely false. A total of 120 questions were included in the study. Among these questions, 50.0% received a grade of 1 (completely correct) (55.4% for 4.0 version). The combined rate of correct answers (grades 1 and 2) was 85.2% for frequently asked questions (88.8% for 4.0 version) and 81.5% for questions obtained from the guideline. The rate of completely incorrect answers (grade 4) was 1.8% for frequently asked questions (0% for 4.0 version) and 5.2% for questions based on strong recommendations. The response rate of version 4.0 to questions created from sentences containing strong recommendations from the EAU guideline was the same as version 3.5. ChatGPT provided satisfactory answers to the questions asked, although some responses lacked completeness. It may be beneficial to utilize ChatGPT under the guidance of a urologist to enhance patients' comprehension of their andrology issues.

Using artificial intelligence to generate medical literature for urology patients: a comparison of three different large language models.

PURPOSE: Large language models (LLMs) are a form of artificial intelligence (AI) that uses deep learning techniques to understand, summarize and generate content. The potential benefits of LLMs in healthcare is predicted to be immense. The objective of this study was to examine the quality of patient information leaflets (PILs) produced by 3 LLMs on urological topics. METHODS: Prompts were created to generate PILs from 3 LLMs: ChatGPT-4, PaLM 2 (Google Bard) and Llama 2 (Meta) across four urology topics (circumcision, nephrectomy, overactive bladder syndrome, and transurethral resection of the prostate). PILs were evaluated using a quality assessment checklist. PIL readability was assessed by the Average Reading Level Consensus Calculator. RESULTS: PILs generated by PaLM 2 had the highest overall average quality score (3.58), followed by Llama 2 (3.34) and ChatGPT-4 (3.08). PaLM 2 generated PILs were of the highest quality in all topics except TURP and was the only LLM to include images. Medical inaccuracies were present in all generated content including instances of significant error. Readability analysis identified PaLM 2 generated PILs as the simplest (age 14-15 average reading level). Llama 2 PILs were the most difficult (age 16-17 average). CONCLUSION: While LLMs can generate PILs that may help reduce healthcare professional workload, generated content requires clinician input for accuracy and inclusion of health literacy aids, such as images. LLM-generated PILs were above the average reading level for adults, necessitating improvement in LLM algorithms and/or prompt design. How satisfied patients are to LLM-generated PILs remains to be evaluated.

Urology pathways for the primary care physician.

Urology provides critical medical treatment that has the potential to save lives and greatly improve quality of life. Although there is a growing need for urological care, South Africa (SA) now faces an unmet need for these services, and junior doctors have limited exposure to urology. SA has a total of 347 urologists who are actively practising and registered with the Health Professions Council of South Africa. This means that there is a ratio of only 0.56 urologists per 100 000 people in the population. The ratio is even more dire if we only include urologists in the public sector. This article offers pragmatic strategies for addressing common urological conditions. These guidelines adhere to international standards and can be adopted at all levels of healthcare, with the exception of a few advanced imaging needs.

Human HPSE2 gene transfer ameliorates bladder pathophysiology in a mutant mouse model of urofacial syndrome.

Rare early-onset lower urinary tract disorders include defects of functional maturation of the bladder. Current treatments do not target the primary pathobiology of these diseases. Some have a monogenic basis, such as urofacial, or Ochoa, syndrome (UFS). Here, the bladder does not empty fully because of incomplete relaxation of its outflow tract, and subsequent urosepsis can cause kidney failure. UFS is associated with biallelic variants of HPSE2, encoding heparanase-2. This protein is detected in pelvic ganglia, autonomic relay stations that innervate the bladder and control voiding. Bladder outflow tracts of Hpse2 mutant mice display impaired neurogenic relaxation. We hypothesized that HPSE2 gene transfer soon after birth would ameliorate this defect and explored an adeno-associated viral (AAV) vector-based approach. AAV9/HPSE2, carrying human HPSE2 driven by CAG, was administered intravenously into neonatal mice. In the third postnatal week, transgene transduction and expression were sought, and ex vivo myography was undertaken to measure bladder function. In mice administered AAV9/HPSE2, the viral genome was detected in pelvic ganglia. Human HPSE2 was expressed and heparanase-2 became detectable in pelvic ganglia of treated mutant mice. On autopsy, wild-type mice had empty bladders, whereas bladders were uniformly distended in mutant mice, a defect ameliorated by AAV9/HPSE2 treatment. Therapeutically, AAV9/HPSE2 significantly ameliorated impaired neurogenic relaxation of Hpse2 mutant bladder outflow tracts. Impaired neurogenic contractility of mutant detrusor smooth muscle was also significantly improved. These results constitute first steps towards curing UFS, a clinically devastating genetic disease featuring a bladder autonomic neuropathy.

[Importance of neuro-urological care in patients with spinal cord injuries/diseases]. / Stellenwert der neuro-urologischen Betreuung von Patienten mit Rückenmarkverletzungen/-erkrankungen.

Integrity, control and regulation of the urinary tract are subject to a complex neuronal regulation, in which portions of the sympathetic, parasympathetic and somatic nervous system are involved. The spinal cord plays a central role in regulation and serves as a transmitter for the motor and sensory pathways. Bladder dysfunction followed by renal dysfunction was the most frequent cause of death in patients with spinal cord injuries/diseases (paraplegia) as recently as half a decade ago. Thanks mainly to diagnostic and therapeutic advances made in neuro-urology, urological problems are no longer life-limiting. A vital role is played not only by the actual function of the urinary tract but also by the complex interactions in patients living with paraplegia. Issues such undertreated hyperactivity of the detrusor muscle with autonomous dysregulation, incontinence with secondary skin changes, or insufficient hand function to perform intermittent catheterisation must be evaluated in an interdisciplinary approach. Spinal cord injury/disease implies numerous functional disorders and secondary impairments of the organism. In addition to bladder function, sexual dysfunction also plays a crucial role. Especially in younger patients who sustain paraplegia before or during the family planning phase, this disruption and limitation is an essential reason for reduced quality of life. Neurogenic intestinal function plays an additional crucial role with regard to quality of life and management of everyday life. In recent years, the range of neuro-urological topics has expanded significantly. The focus of our work shifted from being merely on the urinary tract and urodynamics. In particular, the diagnostic investigation and treatment of neurogenic intestinal dysfunction is increasingly in the hands of neuro-urologists. The complex presentation of paraplegia involves an interaction of bladder, intestinal and sexual dysfunction in a way that these influence one another. Therefore, the sustained care and re-integration of these patients essentially includes lifelong and regular neuro-urological care in a paraplegia centre. Last but not least, it is exactly these neuro-urological topics such as urinary tract infections, urinary and intestinal incontinence and faecal impaction, which most commonly lead to re-hospitalisation.

Epigenetic insights to pediatric uropathology: Celebrating the fundamental biology vision of Tony Khoury.

INTRODUCTION: Many pediatric urology conditions affect putatively normal tissues or appear too commonly to be based solely on specific DNA mutations. Understanding epigenetic mechanisms in pediatric urology, therefore, has many implications that can impact cell and tissue responses to settings, such as environmental and hormonal influences on urethral development, uropathogenic infections, obstructive stimuli, all of which originate externally or extracellularly. Indeed, the cell's response to external stimuli is often mediated epigenetically. In this commentary, we highlight work on the critical role that epigenetic machinery, such as DNA methyltransferases (DNMTs), Enhancer of Zeste Polycomb Repressive Complex 2 Subunit (EZH2), and others play in regulating gene expression and cellular functions in three urological contexts. DESIGN: Animal and cellular constructs were used to model clinical pediatric uropathology. The hypertrophy, trabeculation, and fibrosis of the chronically obstructed bladder was explored using smooth muscle cell models employing disorganised vs. normal extracellular matrix (ECM), as well as a new animal model of chronic obstructive bladder disease (COBD) which retains its pathologic features even after bladder de-obstruction. Cell models from human and murine hypospadias or genital tubercles (GT) were used to illustrate developmental responses and epigenetic dependency of key developmental genes. Finally, using bladder urothelial and organoid culture systems, we examined activity of epigenetic machinery in response to non uropathogenic vs. uropathogenic E.coli (UPEC). DNMT and EZH2 expression and function were interrogated in these model systems. RESULTS: Disordered ECM exerted a principal mitogenic and epigenetic role for on bladder smooth muscle both in vitro and in CODB in vivo. Key genes, e.g., BDNF and KCNB2 were under epigenetic regulation in actively evolving obstruction and COBD, though each condition showed distinct epigenetic responses. In models of hypospadias, estrogen strongly dysregulated WNT and Hox expression, which was normalized by epigenetic inhibition. Finally, DNA methylation machinery in the urothelium showed specific activation when challenged by uropathogenic E.coli. Similarly, UPEC induces hypermethylation and downregulation of the growth suppressor p16INK4A. Moreover, host cells exposed to UPEC produced secreted factors inducing epigenetic responses transmissible from one affected cell to another without ongoing bacterial presence. DISCUSSION: Microenvironmental influences altered epigenetic activity in the three described urologic contexts. Considering that many obstructed bladders continue to display abnormal architecture and dysfunction despite relief of obstruction similar to after resection of posterior valves or BPH, the epigenetic mechanisms described highlight novel approaches for understanding the underlying smooth muscle myopathy of this crucial clinical problem. Similarly, there is evidence for an epigenetic basis of xenoestrogen on development of hypospadias, and UTI-induced pan-urothelial alteration of epigenetic marks and propensity for subsequent (recurrent) UTI. The impact of mechanical, hormonal, infectious triggers on genitourinary epigenetic machinery activity invite novel avenues for targeting epigenetic modifications associated with these non-cancer diseases in urology. This includes the use of deactivated CRISPR-based technologies for precise epigenome targeting and editing. Overall, we underscore the importance of understanding epigenetic regulation in pediatric urology for the development of innovative therapeutic and management strategies.

Clerodendranthus Spicatus: A review of its active compounds, mechanisms of action, and clinical studies in urinary diseases.

Clerodendranthus spicatus (Thunb.) C.Y.Wu (CS) is a widely studied plant that shows potential in treating urinary diseases. Previous studies have focused on its chemical composition, pharmacological effects, and clinical applications. This review aims to provide a comprehensive summary and evaluation of the existing literature on CS. It also suggests future research directions to increase our understanding of its medicinal value. 129 pieces of literature were selected from several databases, including PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), Wan-fang Database, and Google Scholar, and were analyzed. Forty-five active compounds of CS have pharmacological effects such as lowering uric acid, anti-inflammation, anti-oxidation, and kidney protection. The potential mechanisms of these effects may be related to inhibiting transforming growth factor ß1 (TGF-ß1) activation, reducing inflammatory factors such as IL-8, IL-1ß, TNF-α, PGE2, IFN-γ, and IL-6 levels, suppressing the activation of NF-κB, JAK/STAT pathway, enhancing the clearance of ROS, MDA DPPH·, and O2 ̇ -, and regulating the expression of apoptosis-related pathways and proteins. This paper also discusses the quality control of CS and its efficacy and safety in treating urinary diseases. The study concludes that CS has a high potential for treating urinary diseases. Future studies should focus on observing the metabolic changes of CS active compounds in vivo and investigating the effects of CS on key signaling pathways. Additionally, more standardized and reasonable clinical studies and safety evaluation experiments should be conducted to obtain more clinical data.

Emergency endovascular and percutaneous urological interventions encompass various diagnostic and therapeutic procedures to address various genitourinary conditions. These urological interventions are life-saving in addressing complications following biopsy, post-nephrectomy, post-transplant, and post-trauma. Compared to other surgical fields, there are relatively fewer urological emergencies. However, they require prompt radiological diagnosis and urgent interventions. This pictorial essay emphasizes various urological emergencies and urgent interventional management.

Diagnosis in Bytes: Comparing the Diagnostic Accuracy of Google and ChatGPT 3.5 as an Educational Support Tool.

BACKGROUND: Adopting advanced digital technologies as diagnostic support tools in healthcare is an unquestionable trend accelerated by the COVID-19 pandemic. However, their accuracy in suggesting diagnoses remains controversial and needs to be explored. We aimed to evaluate and compare the diagnostic accuracy of two free accessible internet search tools: Google and ChatGPT 3.5. METHODS: To assess the effectiveness of both medical platforms, we conducted evaluations using a sample of 60 clinical cases related to urological pathologies. We organized the urological cases into two distinct categories for our analysis: (i) prevalent conditions, which were compiled using the most common symptoms, as outlined by EAU and UpToDate guidelines, and (ii) unusual disorders, identified through case reports published in the 'Urology Case Reports' journal from 2022 to 2023. The outcomes were meticulously classified into three categories to determine the accuracy of each platform: "correct diagnosis", "likely differential diagnosis", and "incorrect diagnosis". A group of experts evaluated the responses blindly and randomly. RESULTS: For commonly encountered urological conditions, Google's accuracy was 53.3%, with an additional 23.3% of its results falling within a plausible range of differential diagnoses, and the remaining outcomes were incorrect. ChatGPT 3.5 outperformed Google with an accuracy of 86.6%, provided a likely differential diagnosis in 13.3% of cases, and made no unsuitable diagnosis. In evaluating unusual disorders, Google failed to deliver any correct diagnoses but proposed a likely differential diagnosis in 20% of cases. ChatGPT 3.5 identified the proper diagnosis in 16.6% of rare cases and offered a reasonable differential diagnosis in half of the cases. CONCLUSION: ChatGPT 3.5 demonstrated higher diagnostic accuracy than Google in both contexts. The platform showed satisfactory accuracy when diagnosing common cases, yet its performance in identifying rare conditions remains limited.

[Pain therapy in urology-overview of current S3 guideline recommendations]. / Schmerztherapie in der Urologie ­ Überblick zu aktuellen Empfehlungen der S3-Leitlinen.

Dealing efficiently with patients suffering from pain is a central medical task. Pain, as an important function in developmental physiology, warns against damage to the body caused by external noxious agents as well as internal malfunctions and requires special attention in modern medicine. Peri- and postoperative pain is known to have a negative influence on postoperative convalescence. Treatment of tumor-related pain represents another relevant challenge in uro-oncology and palliative medicine. The updated guideline on perioperative pain therapy and palliative medicine for patients with incurable diseases or cancer is dedicated to these two topics.
