The Spanish version of Qualiveen functions similarly to the English language version retaining its discriminating power. It has shown it could be a valid instrument for discriminating between patients in a cross-sectional survey, as well as for measuring within subject changes over time thus evaluating the extent to which MS patients' HRQoL is impaired by urinary-related problems.

Objectives: To determine the incidence of computed tomography (CT) identifiable Randall plaques in a CT explored population; to determine the clinical relevance of this radiological finding by a 7-year follow-up; to determine a cut point to identify a population with high risk of developing calcium stone disease (SD). Materials and Methods: Retrospective study of all patients explored by abdominal CT in our center between January and March 2005. Inclusion criteria: age 30-60 years and no SD. Papillae attenuation was measured on nonenhanced CT in Hounsfield units (HU) and the mean of all papillae was calculated. Patients were reevaluated after 7 years to identify calcium stone formers. Anamnesis and already available CT, ultrasound, kidney, ureter, and bladder radiograph (KUB) or intravenous urography (IVU) images performed as part of their follow-up were used. In patients with no follow-up, ultrasound and KUB were to be performed. Pearson correlation, Student t-test, and the receiver operator curve were used for statistical analysis. Results: A total of 362 patients fulfilled the inclusion criteria and were analyzed; 12 developed calcium SD after 7 years. A significant difference was encountered between the papillae attenuation of stone formers (SF) versus non-SF (47.2HU vs. 35.5HU, p = 0.001). There was good correlation between papillae attenuation and the possibility of developing SD (R = 0.87). An optimal cut point of 43HU with a sensitivity of 81% and specificity of 97%, area under the curve 0.91, separated SF and non-SF. Conclusion: Patients with high papillae density have a higher risk of developing SD. A cut point of 43HU could accurately be used to identify a high-risk population.

We found no statistical difference between water and air cystoscopy in patients without hematuria. Air cystoscopy had higher sensitivity and specificity for diagnosing active hematuria while adding almost no specific complications to the procedure.
