Automated detection of posterior urethral valves in voiding cystourethrography images: A novel AI-Based pipeline for enhanced diagnosis and classification.

Introduction: Posterior Urethral Valves (PUV) are rare congenital anomalies of the male urinary tract that can lead to urethral obstruction and increased risk of kidney disease. Traditional diagnosis relies on subjective interpretation of imaging techniques. This study aimed to automate and increase accuracy of PUV detection in voiding cystourethrography (VCUG) images using an AI-based pipeline.

Aldehyde free - Bovine Pericardium - A New Option of Graft in Urethral Stricture Treatment.

Objective: The current management for complex urethral strictures commonly uses open reconstruction with buccal mucosa urethroplasty. However, there are multiple situations whereby buccal mucosa is inadequate (pan-urethral stricture or prior buccal harvest) or inappropriate for utilization (heavy tobacco use or oral radiation). Multiple options exist for use as alternatives or adjuncts to buccal mucosa in complex urethral strictures (injectable antifibrotic agents, augmentation urethroplasty with skin flaps, lingual mucosa, bladder mucosa, colonic mucosa, and new developments in tissue engineering for urethral graft material) (1, 2).

Anal Sphincter Reconstruction Using the Posterior Sagittal Approach for Pediatric Perineal Trauma.

Traumatic perineal injuries are rare but can result in significant morbidity, particularly when the anal sphincter is injured. The management of such injuries in the pediatric population is rarely noted in the literature. We aimed to describe reconstruction in such patients using lessons learned in reoperative anorectal malformation surgery.

Verification of a system utilizing heartbeat-induced acoustic pulse waves for estimating the time at which bladder urine increases to a level requiring drainage among individuals with spinal cord injury.

Background: Spinal cord injury (SCI) often leads to the loss of urinary sensation, making urination difficult. In a previous experiment involving six healthy participants, we measured heartbeat-induced acoustic pulse waves (HAPWs) at the mid-back, calculated time-series power spectra of heart rate gradients at three ultralow/very low frequencies, distinguished and formulated waveform characteristics (one characteristic for each power spectrum, nearly uniform across participants) at times of increased urine in the bladder and heightened urges to urinate, and developed an algorithm with five of these power spectra to identify when urination is needed by extracting the waveform portion (continuous timepoints) where all of the characteristics were consistent with the formulated characteristics. The objective of this study was to verify the validity of the algorithm fed with data from measured HAPW of participants with SCI and to adapt the algorithm for these individuals.

Utilizing the Ellik bladder evacuator during cystoscopic retrieval of urocystoliths in 12 dogs.

Incidence of urethrocutaneous fistula after distal and midshaft hypospadias repair does not differ among patients treated with or without a protective second-layer: single tertiary centre experience.

Introduction: Urethrocutaneous fistula (UCF) is the most common complication after hypospadias repair, with an variable incidence of 2-35%, depending on defect type. The interposition of tissue between the neourethra and the skin or glans is considered an important factor to reduce the risk of UCF. Literature has focused on the comparison of different types of second layers, but there is still no consensus regarding the best tissue to adopt.

The Neisseria meningitidis urethritis clade (NmUC) acts as a "chimeric pathogen" during infection of primary, human male, urethral epithelial cells.

Background: Clusters of male urethritis cases, caused by a novel clade of non-groupable Neisseria meningitidis (NmUC, "the clade"), have been reported globally. Genetic features unique to NmUC isolates include: the acquisition of the gonococcal denitrification loci, norB-aniA; a unique factor H binding protein (fHbp) variant; and loss of group C capsule and intrinsic lipooligosaccharide sialylation. We hypothesized that these characteristics might confer a colonization and survival advantage to NmUC during male urethral infection relative to non-clade group C Neisseria meningitidis.

A 36-year-old man with severe Crohn disease complicated by urethral strictures and enterocutaneous and enterovesicular fistulas presented for several weeks of poor appetite, weight loss, failure to thrive, and newly worsening altered mentation. Further history revealed he chronically did not urinate through his urethra, but rather "leaked" through multiple enterocutaneous fistulas in his abdomen and perineum. Medications included ustekinumab (anti-IL12/IL23 monoclonal antibody) for Crohn disease, methadone, and hydrocodone.

Additive outcome of platelet rich fibrin neourethral coverage of tubularized incised plate in primary distal hypospadias repair.

Background: Healing complications are a significant concern after hypospadias repair, often attributed to deficient growth factors and reduced healing potential of hypospadiac tissue. Platelet-Rich Fibrin (PRF), a new generation of platelet concentrates rich in growth factors, has been successfully applied to provide a mechanical barrier and promote healing in different surgical fields. The objective of this study was to assess the role of a PRF membrane covering the neourethra, in addition to a Dartos flap, optimizing the outcomes of primary distal hypospadias repair.
