Background: Our objective was to describe day-to-day evolution and variations in patient-reported stent-associated symptoms (SAS) in the STudy to Enhance uNderstanding of sTent-associated Symptoms (STENTS), a prospective multicenter observational cohort study, using multiple instruments with conceptual overlap in various domains.
Methods: In a nested cohort of the STENTS study, the initial 40 participants having unilateral ureteroscopy (URS) and stent placement underwent daily assessment of self-reported measures using the Brief Pain Inventory short form, Patient-Reported Outcome Measurement Information System measures for pain severity and pain interference, the Urinary Score of the Ureteral Stent Symptom Questionnaire, and Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index. Pain intensity, pain interference, urinary symptoms, and bother were obtained preoperatively, daily until stent removal, and at postoperative day (POD) 30.
Results: The median age was 44 years (IQR 29,58), and 53% were female. The size of the dominant stone was 7.5 mm (IQR 5,11), and 50% were located in the kidney. There was consistency among instruments assessing similar concepts. Pain intensity and urinary symptoms increased from baseline to POD 1 with apparent peaks in the first 2 days, remained elevated with stent in situ, and varied widely among individuals. Interference due to pain, and bother due to urinary symptoms, likewise demonstrated high individual variability.
Conclusions: This first study investigating daily SAS allows for a more in-depth look at the lived experience after URS and the impact on quality of life. Different instruments measuring pain intensity, pain interference, and urinary symptoms produced consistent assessments of patients' experiences. The overall daily stability of pain and urinary symptoms after URS was also marked by high patient-level variation, suggesting an opportunity to identify characteristics associated with severe SAS after URS.

Voiding cystourethrography (VCUG) is indicated for evaluating the anatomy of the urethra and bladder. It is primarily used to diagnose vesicoureteral reflux (VUR) and posterior urethral valves (PUV), especially in cases of febrile urinary tract infections (UTIs), significant ureteral dilation on ultrasound, and-in continent children-urinary symptoms suggestive of infravesical obstruction. VCUG exposes children to a non-negligible dose of radiation and requires urethral catheterization, which can be painful-particularly in males-and carries a low but present risk of post-procedural UTI.

Tamsulosin is a highly selective α1A adrenergic receptor antagonist that can relax smooth muscles in the urethra, bladder neck, and prostate and improve urinary disorders. It is therefore widely used to treat lower urinary tract symptoms caused by benign prostatic hyperplasia. The aim of this study is to evaluate the pharmacokinetic (PK) characteristics and bioequivalence of 2 different formulations (tamsulosin sustained-release tablets and tamsulosin sustained-release capsules) in healthy Chinese subjects.

The human kidneys play a pivotal role in regulating blood pressure, water, and salt homeostasis, but assessment of renal function typically requires invasive methods. Deuterium metabolic imaging (DMI) is a novel, noninvasive technique for mapping tissue-specific uptake and metabolism of deuterium-labeled tracers. This study evaluates the feasibility of renal DMI at 7-Tesla (7T) to track deuterium-labeled tracers with high spatial and temporal resolution, aiming to establish a foundation for potential clinical applications in the noninvasive investigation of renal physiology and pathophysiology.

Introduction Nephrogenic diabetes insipidus (NDI) is a rare condition caused by renal resistance to the action of antidiuretic hormone (ADH) at the level of the distal tubule, resulting in impaired urinary concentration and consequent polyuria. NDI may be hereditary, most commonly X-linked due to AVPR2 gene mutations, or acquired. Objective To characterize the clinical features, management strategies, and outcomes of patients with NDI followed at a tertiary pediatric nephrology center.
