Objective: To investigate the safety, efficacy, and surgical approach of percutaneous bladder calculi removal in adult patients with prior lower urinary tract reconstruction utilizing bowel using a single-institution database.
Methods: Twenty patients with prior history of lower urinary tract reconstruction (continent cutaneous urinary reservoir, augmentation enterocystoplasty with catheterizable channel, or ileal neobladder) who underwent percutaneous cystolitholapaxy from 2014 to 2020 were identified from an IRB-approved database. Analysis of patient demographics, operative details, stone composition, stone-free rates, recurrence, and associated complications was performed.
Results: Percutaneous access and either ultrasonic lithotripter or laser lithotripsy were utilized to remove bladder stones. Over half of the patients also underwent concomitant renal stone removal via percutaneous removal or retrograde ureteroscopy. Postoperative computed tomography imaging revealed complete bladder stone clearance in 90% of patients. There were no notable complications from percutaneous bladder stone removal and most patients were discharged either the same day or within 24hours. Urine and stone analysis revealed infection was present in the majority of patients. Bladder stones recurred in 45% of patients after more than 2years of follow-up, on average.
Conclusion: Percutaneous cystolitholapaxy is a safe and effective approach for the removal of moderate-sized bladder calculi in adults with prior lower urinary tract reconstruction utilizing bowel. Its efficacy and minimally invasive nature make it the approach of choice at our institution.

Comparing integrative ventilatory and renal acid-base acclimatization in lowlanders and Tibetan highlanders during ascent to 4,300 m.

With over 14 million people living above 3,500 m, the study of acclimatization and adaptation to high altitude in human populations is of increasing importance, where exposure to high altitude (HA) imposes a blood oxygenation and acid-base challenge. A sustained and augmented hypoxic ventilatory response protects oxygenation through ventilatory acclimatization, but elicits hypocapnia and respiratory alkalosis. A subsequent renally mediated compensatory metabolic acidosis corrects pH toward baseline values, with a high degree of interindividual variability.

Transrectal (TR) biopsy has traditionally been the gold standard for diagnosis, but transperineal (TP) biopsy is increasingly favoured due to its lower infection risk. However, debate remains regarding which method has superior cancer detection rates.

Background: Plasma membrane tension-related genes (MTRGs) are known to play a crucial role in tumor progression by influencing cell migration and adhesion. However, their specific mechanisms in bladder cancer (BLCA) remain unclear.
Methods: Transcriptomic, clinical and mutation data from BLCA patients were collected from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases.

Background: In patients undergoing orthopaedic trauma surgery, acute kidney injury (AKI) can develop post-operatively and is a major cause of increased mortality and hospital stay time. Development of AKI is associated with three main processes: inflammation, ischaemia-reperfusion injury (IRI) and hypoperfusion. In this study, we investigated whether ratios of urine and blood anti-inflammatory biomarkers and biomarkers of hypoperfusion, IRI and inflammation are elevated in patients who develop post-trauma orthopaedic surgery acute kidney injury (PTOS-AKI).
