PURPOSE We determined whether increasing the number of cores at first prostate biopsy would improve the cancer detection rate without increasing the detection of clinically insignificant tumors. MATERIALS AND METHODS From January 2009 to January 2010 patients scheduled for prostate biopsy were randomized to 12 or 18-core sampling. Study inclusion criteria(More)
INTRODUCTION Metabolic syndrome (MS) is linked to hormone-dependent cancers. Its prognostic implication in prostate cancer (PCa) is unclear. We analyzed the impact of MS in the survival of men with PCa treated surgically. PATIENTS AND METHODS We studied patients with PCa, treated surgically between 1990 and 2007, and compared the survival of men with MS(More)
OBJECTIVES To develop and to validate the Spanish version of the Ureteral Stent Symptom Questionnaire (USSQ). Describe the prevalence of symptoms associated with the presence of ureteral stent in a Spanish-speaking population.

MATERIAL AND METHODS Of 262 patients admitted with acute pyelonephritis, 18 had CT findings of EPN. The Wan and Huang classifications were used. We assessed the clinical,(More)
OBJECTIVE To analyze the outcomes of emphysematous pyelonephritis (EPN), the impact of different treatment modalities, and to determine risk factors associated with mortality. METHODS We retrospectively reviewed cases of EPN from 3 tertiary care institutions in Mexico. The diagnosis was confirmed with computed tomographic scan. Treatment was classified as(More)
PURPOSE Areas of lower enhancement on computed tomography are frequently seen in renal-cell carcinoma. We investigated whether tumor enhancement on the most prominent hypodense areas correlates with the nuclear grade and other pathologic variables. METHODS From 2004 to 2009, all consecutive patients with a preoperative tomography who underwent radical or(More)
INTRODUCTION We evaluate volumetry and RECIST (Response Evaluation Criteria In Solid Tumors) as methodologies for response after chemotherapy for non-seminomatous germ cell tumour with retroperitoneal lymph node metastases. METHODS We performed a retrospective analysis of non-seminomatous testicular tumours and concurrent retroperitoneal lymph node(More)
OBJECTIVE To evaluate the prognostic impact of early recurrence (within 12 months) after surgery on cancer-specific survival (CSS) of patients with localized clear-cell renal cell carcinoma (ccRCC). METHODS Patients with surgically treated localized ccRCC were studied. Using the Kaplan-Meier method, we calculated CSS; by univariate and multivariate models(More)
OBJECTIVE To assess the prevalence and risk factors of erectile dysfunction (ED) in HIV patients from the HIV clinic of a tertiary referral center in Mexico City. DESIGN Prevalence was obtained from cross-sectional studies, and the International Index of Erectile Function (IIEF), a standardized method, was used to assess ED. METHODS A cross-sectional(More)
