The orthogonal and unitary calculi give a method to study functors from the category of real or complex inner product spaces based topological spaces. We construct between complexification-realification adjunction These allow for movement versions calculi, comparisons Taylor towers produced by both calculi. show that when inputted functor is weakly polynomial, tower restricted through realifica...

Primary renal squamous cell carcinoma (SCC) is a rare primary malignancy of the kidney. Diagnosis is usually delayed because of its lack of characteristic clinical and imaging features and inherent aggressive nature. We present a case of primary renal SCC in a 66-year-old woman with bilateral renal calculi and a complex right lower pole renal mass. The diagnosis of primary renal SCC was establi...

Percutaneous nephrolithotomy has revolutionized the ability of the urologist to remove large burdens of renal stones over the last 15 years. In the United States, it has largely replaced open stone surgery for the treatment of large sized stones. One of the key factors in optimizing outcomes for this procedure is accurate percutaneous renal access. The guiding principles for effective renal acc...

Experience with horseshoe kidney transplantation is limited. Horseshoe kidney may be underutilized for transplantation because of the greater incidence of vascular and other associated urological anomalies. Nowadays, owing to a greater number of patients waiting for a kidney donation and to a shortage of organs donated, more suitable organ acceptance criteria have been formulated. The aim of th...

We single out some problems of Schubert calculus of subspaces of codimension 2 that have the property that all their solutions are real whenever the data are real. Our arguments explore the connection between subspaces of codimension 2 and rational functions of one variable.

INTRODUCTION Twitter is a popular microblogging platform for the rapid dissemination of information and reciprocal exchange in the urological field. We aimed to assess the activity, users and content of the online discussion, #KidneyStones, on Twitter. METHODS We investigated the Symplur Signals analytics tool for Twitter data distributed via the #KidneyStones hashtag over a one year period. ...

Isolated involvement of the kidneys by ray fungus is very rare. Cope (1938) had found only 20 cases in the literature. Baron and Arduino (1949) reported what they considered the twentieth case of primary or solitary actinomycosis of the kidney. Wilson-Pepper (1951) published the report of a case of actinomycosis of the right kidney which was also the seat of calculus pyonephrosis. The case repo...

The prevalence of kidney stone disease is increasing, and newer research is finding that stones are associated with several serious morbidities. These facts suggest that emphasis needs to be placed not only on stone treatment but also stone prevention. However, there is a relative dearth of information on dietary and medical therapies to treat and avoid nephrolithiasis. In addition, studies hav...
