Abstract Bladder cancer (BCa) diagnosis relies heavily on cystoscopy and imaging. Both have limited sensitivity and accuracy, particularly for muscle-invasive disease. Artificial intelligence (AI) has emerged as a promising tool for improving detection, grading, and staging by extracting imaging features that exceed human perception. We conducted a narrative review of peer-reviewed, English-language studies published between 2015 and 2025. We identified 75 articles and synthesized data from 35 key studies retrieved via PubMed, Google Scholar, Scopus, and Embase. Data were synthesized narratively, emphasizing diagnostic performance, clinical relevance, and study limitations. In cystoscopy, AI models achieved high accuracy… More >

Abstract Ketamine is a potent anaesthetic drug that has been used for decades. Ketamine abuse is an increasingly common problem, particularly among young people. Over one quarter of ketamine users will have at least one bothersome urological symptom, with heavier and longer use leading to potentially irreversible damage to the lower and upper urinary tract. Hence, this study carried out a narrative review focusing on ketamine-induced uropathy pathophysiology, clinical presentation, and treatment options. It was found that ketamine uropathy is an inflammatory condition affecting predominantly the bladder but also the upper urinary tracts. A hypersensitivity reaction… More >

Abstract Pediatric patients with functional or anatomical lower urinary tract obstruction, including neurogenic bladder, require effective bladder drainage to maintain low intravesical pressures, prevent infections, and preserve renal function. Clean intermittent catheterization (CIC) is the standard approach, but it is not always feasible due to patient- or anatomy-related factors. In these cases, continent or non-continent urinary diversion techniques are considered. Among non-continent options, vesicostomy has traditionally been used but is associated with significant morbidity and long-term complications. The cystostomy button (CB), originally developed for enteral feeding, has emerged as a minimally invasive, catheterizable alternative for bladder More >

Abstract Backgrounds: Holmium laser enucleation of the prostate (HoLEP) is a widely accepted technique for treating benign prostatic hyperplasia (BPH). Developed in the 1990s, its safety and efficiency have improved with adenoma morcellation. Multiple morcellation devices exist, with oscillatory systems offering higher efficiency and safety. Notable among these are the DrillCut Storz™ (DC) and the Multicut SOLO Jena Surgical™ (MC). Currently, evidence on the efficiency of MC is limited, and no comparative analysis exists between oscillatory morcellators. The objective of this study is to compare the morcellation efficiency (g/min) of the DC and the MC. A… More >

Abstract Background: Interstitial cystitis (IC) is a chronic condition characterized by frequent urination, urgency, and pelvic pain. While its pathogenesis remains incompletely understood, the prevailing epithelial theory suggests that a defective glycosaminoglycan (GAG) layer increases bladder permeability, allowing urinary toxins to chronically stimulate the detrusor muscle and activate mast cells. Current therapies, such as intravesical hyaluronic acid instillation, have demonstrated limited efficacy. This study aimed to evaluate the feasibility of sterile recombinant human collagen type III (rHCIII) in mitigating bladder injury and its histological effects on urothelial integrity.

Abstract Erectile dysfunction (ED) has evolved from a quality-of-life concern to a recognized marker of systemic vascular disease and an early harbinger of cardiovascular events. The Princeton IV Consensus underscores that men presenting with erectile dysfunction should be presumed at increased cardiovascular risk until proven otherwise, advocating integrated risk stratification and lifestyle optimization. Beyond established risk scores, advances in omics, vascular imaging, and digital health promise precision tools for early detection and prevention. This review aims to examine erectile dysfunction as an early marker of cardiovascular disease and to summarize current and emerging approaches to cardiovascular More >

Abstract Background: Retrograde urethrogram (RUG) remains the gold standard for diagnosing urethral stricture disease, however no widely available diagnostic modality currently quantifies stricture characteristics using cross-sectional area or tissue compliance. We hypothesized that pressure-derived metrics could improve diagnostic accuracy and guide treatment. We aimed to develop an in vitro latex urethra model to simulate “healthy” and “strictured” states and directly measure luminal pressure as an initial step toward compliance assessment. Methods: Ten 20-cm latex tubes were studied; five contained 1.5-cm simulated strictures. All tubes were clamped at both ends to prevent leakage. Strictures were created by clamping… More >
