To determine how the LURN-SI-10, a novel questionnaire developed by the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN), compares with the International Prostate Symptom Score (IPSS) in men with lower urinary tract symptoms (LUTS) attributed to benign prostatic hyperplasia (BPH). Specifically, to assess convergent validity and determine how frequently the LURN-SI-10 identifies symptoms not captured by the IPSS.Men presenting with BPH/LUTS were prospectively administered LURN-SI-10 and IPSS questionnaires. Urinary incontinence (UI) including post-void dribbling (PVD), urgency urinary incontinence (UUI), stress urinary incontinence (SUI), as well as bladder pain were considered present if the patient reported "about half the time or more" on LURN-SI-10. Correlations between LURN-SI-10 and IPSS were assessed as continuous and categorical variables. Multivariable linear regression analysis was performed to determine associations with symptom scores.LURN-SI-10 and IPSS were highly correlated in men with BPH/LUTS (r = 0.82, n = 429), as were respective bother and quality of life scores (ρ = 0.74). The LURN-SI-10 identified additional symptoms including PVD (24%), UUI (13%), SUI (2%), and pain (8%). Men with any UUI, SUI, or PVD had on average a 7.6-point higher LURN-SI-10 score than those without UI (P.001) and 8.0-point higher IPSS score than those without UI (P.001).The LURN-SI-10 correlates strongly with the IPSS, but the LURN-SI-10 identifies additional important symptomatology in men with LUTS. This additional information may improve the evaluation and treatment of men with BPH/LUTS. Further prospective studies of the LURN-SI-10 is warranted.

INTRODUCTION AND OBJECTIVE:The Lower Urinary Tract Dysfunction Research Network (LURN) developed a 10-item symptom index (LURN SI-10) designed for practical clinical use in both men and women for t...

Renal angiomyolipomas are benign tumors of the kidney that belong to the ‘PEComa: perivascular epithelioid cell’ family. Epithelioid AMLs (eAML) are a rare monotypic subtype with malignant potential, that can occur sporadically or be associated with tuberous sclerosis (TSC). Due to their epithelioid nature, eAMLs can closely resemble high-grade renal cell carcinoma ( RCC ), which may result in misdiagnosis . Multiple clinicopathologic parameters are predictive of worse outcomes for patients with eAML. Those can be used to stratify patients into groups with low, intermediate and high risk for disease progression. A high index of suspicion and a thorough immunohistochemical study are required to correctly diagnose eAML. Radiographically, eAMLs are also a diagnostic challenge as they share features with RCC on CT and MR imaging. Due to this close mimicry, the true incidence of eAML is thought to be much higher than 200 cases as reported in the literature. We report a series of four patients diagnosed with eAML and compare their clinical courses. We also report on the successful treatment of a patient with pulmonary metastasis from eAML using the mTOR inhibitor, everolimus. By identifying eAML and recognizing its high-risk features, it is possible mTOR inhibitors may have a meaningful role in the adjuvant treatment of these patients.
