Usefulness of measuring renal papillae in Hounsfield units in stone - forming patients.

Introduction: The aim of this work is to study the density of the renal papillae in stone-forming patients and to determine its usefulness.

Materials And Methods: This study included a total of 79 patients diagnosed with renal stones and on whom a computed tomography without contrast was performed from June 2014 to May 2015. The patients were divided into two groups: Group 1 (single ep¬isode) included 43 patients, and Group 2 (recurrent episodes) included 36 patients.

Use of urinary concentrations in mg/dl in relation to absolute values in 24-hour samples for the evaluation of lithogenic factors in stone forming patients.

Objective: The aim of this study is to analyze urine concentrations (mg/dl) of different lithogenic factors in a sample of 24 h as a predictor of these changes rather than absolute values depend on the volume of diuresis.

Methods: A total of 131 patients from the North Almeria Health Management Area (Spain) with urinary calstone disease in whom a metabolic study was indicated were included from June 2014 to May 2015. The concentrations of calcium, oxalate, uric acid, citrate and magnesium were measured in the urine, and the calcium/citrate ratio was calculated.

Outpatient holmium laser treatment for recurrent low-grade superficial bladder cancer under local anesthesia.

Background: The aim of this paper is to analyze the results of a prospective study conducted on a cohort of patients undergoing outpatient holmium laser fulguration. The "gold standard" treatment of superficial bladder cancer is transurethral resection, although in recent years improvements in laser technology and endoscopy equipment have allowed further therapeutic alternatives.

Methods: This is a descriptive study of a cohort of 37 patients with low-risk recurrent superficial bladder cancer undergoing holmium laser fulguration after bladder instillation of local anesthesia.

Seminal vesicle biopsies: an useful staging procedure-exposure of seminal vesicle biopsies protocol and review of the literature.

Background And Objectives: Although new MRI techniques have a high sensitivity but varying specificity with regard to diagnosing the seminal vesicle invasion (SVI) of prostate cancer, the low availability and high cost involved demands incorporating an inexpensive and accessible technique that might support adequate staging. Currently, uniformity does not exist with regard to the indication criteria of seminal vesicle biopsies (SVBs). Our objective is to analyse the protocol of SVBs at Morales Meseguer Hospital and conduct an exhaustive review of the literature in this field.
