Cystectomy and urinary bladder substitution are rare in children but may be necessary in some cases of bladder exstrophy, in the setting of malignancy, or in other settings in which the bladder is severely dysfunctional. This article details advances in surgical techniques in creating continent urinary diversions in this specialized pediatric population.

The association between animal protein, plant protein, and their substitution with bladder cancer risk: a pooled analysis of 10 cohort studies.
Eur J Nutr
December 2024
Department of Epidemiology, Maastricht University, Universiteitssingel 40 (Room C5.570), Maastricht, 6229 ER, The Netherlands.
Purpose: Although total dietary protein intake has been associated with bladder cancer (BC) risk, the effect of the origin (plant or animal) and the substitutions remain to be understood. This study aimed to investigate the effect of total dietary protein, animal-based protein, plant-based protein, and their substitutions with each other on the risk of BC using a pooled analysis of 10 cohort studies.
Methods: The study was conducted within the "BLadder cancer Epidemiology and Nutritional Determinants" (BLEND) study, including 10 prospective cohort studies from several European countries, the United Kingdom, and the United States.
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.

Background: Catatonia is an underdiagnosed neuropsychiatric condition, with only a few studies focusing on medical sequalae among elderly populations. Delayed treatment results in complications with high morbidity and mortality. Among elderly individuals, one such complication is urinary retention.

Implantable medical devices have played a significant role in improving both medical care and patients' quality of life. Urinary Catheters (UCs) are commonly utilized as a substitute for bladder drainage and urine collection to prevent urinary retention in patients. However, bacterial colonization and biofilm formation on the catheter surface are prone to occur, leading to catheter-associated urinary tract infections (CAUTIs) and other complications.

Background: Antibiotic resistance complicates treatment of urinary infections, particularly when these ascend above the bladder, with few oral options remaining. New oral β-lactamase inhibitor combinations present a potential answer, with ceftibuten/avibactam-now undergoing clinical trials-widely active against strains with ESBLs and serine carbapenemases. To inform its development we undertook mutant selection studies.
