Establishing initial resting abdominal pressure in children undergoing urodynamics.

Kidney and Urology Institute, Medanta Hospital, Lucknow, India.
Introduction: The International Continence Society recommends zeroing of transducers to the atmospheric pressure for invasive urodynamics. The range of abdominal pressure relative to atmospheric pressure is well-known in adults but has not been described in children. This prospective observational study was carried out to establish baseline abdominal in children.

Rationale And Objectives: To investigate the feasibility of amide proton transfer-weighted (APTw) and diffusion-weighted Magnetic Resonance Imaging (MRI) as a means by which to add value to the Vesical Imaging Reporting and Data System (VI-RADS) for discriminating muscle invasive bladder cancer (MIBC) from nonmuscle invasive bladder cancer (NMIBC).
Materials And Methods: This prospective study enrolled participants with pathologically confirmed bladder cancer (BCa) who underwent preoperative multiparametric MRI, including APTw and diffusion-weighted MRI, from July 2020 to January 2023. The exclusion criteria were lesions smaller than 10 mm, missing smooth muscle layer in the operation specimen, neoadjuvant therapy before MRI, inadequate image quality, and malignancy other than urothelial neoplasm.

Bladder neck contracture after prostate surgery is a rare but feared complication. The treatment of choice is endoscopic incision or resection of fibrotic tissue. In case of ineffective transurethral correction, bladder neck reconstruction has to be done.

Background: Persistent uroliths after a cystotomy in dogs are a common cause of surgical failure.
Objectives: This study examined the following: the success rate of retrograde urohydropropulsion in male dogs using non-enhanced computed tomography (CT), whether the CT mean beam attenuation values in Hounsfield Units (mHU) measured could predict the urolithiasis composition and whether the selected reconstruction kernel may influence the measured mHU.
Methods: All dogs and cats that presented with lower urinary tract uroliths and had a non-enhanced CT preceding surgery were included.
The urethra in continence and sensation: Neural aspects of urethral function.

Experimental Biology Unit, Department of Biomedicine, Faculty of Medicine of Porto, University of Porto, Porto, Portugal.
Aims: Traditionally, the urethra has been considered a mere conduit to guide urine from the bladder to the external side of the body. Building evidence indicates that the urethra may directly influence bladder function via mechanisms restricted to the lower urinary tract (LUT).
Methods: Here, we discuss the tissue arrangement of the urethra and addressed the contribution of new paraneuronal cells to LUT function.
