To identify the characteristics of patients with sepsis or acute pyelonephritis (APN) combined with ureteral calculi and to analyze the risk factors in its causation. Methods: We included patients with sepsis or APN caused by ureteral calculi who received treatment in the United States from January 2003 to December 2017 using the Optum® deidentified Clinformatics® Datamart. Demographic factors and risk factors for the receipt of sepsis or APN were subsequently analyzed for statistical significance. Results: Of 467,502 urinary stone patients, age-matched multivariate analysis revealed that a history of urinary tract infection (OR 11.31, 95% CI 10.68–11.99, p < 0.0001) and female gender (OR 2.73, 95% CI 2.62–2.84, p < 0.0001) were significantly related to an increased risk of sepsis or APN. Conversely, a previous past medical history of urolithiasis (OR 0.91, 95% CI 0.87–0.95, p < 0.0001) and cancer (OR 0.91, 95% CI 0.87–0.95, p < 0.0001) were associated with a decreased risk of sepsis or APN. With regards to comorbidities, when more than one comorbidity was present, there was an additive effect with higher OR point estimates, rising to 11.31 (10.68–11.99) when three or more comorbidities present. History of urinary tract infection and female gender are risk factors for sepsis or APN in patients with ureteral calculi. Conclusions: This large national cohort reveals the characteristics of sepsis or APN combined with ureteral stone and provides an important baseline for the treatment of urolithiasis in the future.

Background: Transurethral resection of the prostate (TURP) is the gold-standard treatment for benign prostatic hyperplasia (BPH). However, laser surgery techniques (e.g., photoselective vaporization of the prostate (PVP), holmium laser, thulium laser enucleation of the prostate (HoLEP or ThuLEP)), and minimally invasive treatment options (e.g., UroLift) are increasingly replacing TURP. This study seeks to report the annual incidence, management trends, and costs of BPH procedures in the U.S. Methods: Data analyses of U.S. health insurance claims from 2004 to 2017, collected from the de-identified Optum Clinformatics Claims Database, were performed to determine the number of BPH patients and the treatment selected. Results: A total of 51,448 patients underwent BPH procedures from 2004 to 2017. There was a significant increase in the annual rate from 770 in 2004 to 6571 in 2017. The mean patient age (±SD) increased from 67.6 years old (±8.4) in 2004 to 73.4 years old (±8.4) in 2017. More than 60% of patients underwent cystourethroscopy and a post-void residual urine check for workup prior to surgical management. TURP was the most-common, and PVP was the second-most-common BPH procedure. Medical and total treatment costs increased, while the detection rate of prostate cancer after BPH surgery gradually decreased from 19.87% in 2004 to 5.78% in 2017. Conclusions: Our study demonstrates a recent trend in BPH management that replaces the traditional TURP technique with alternative methods. Due to rising costs, future studies should assess whether these newer methods are cost effective over the long term. [ABSTRACT FROM AUTHOR]
