Erectile dysfunction (ED), a frequent complaint in the primary care setting, is strongly associated with obesity, cigarette smoking and other common cardiovascular risk factors like hypertension, diabetes mellitus (DM), lipid disorders and the metabolic syndrome. The prevalence of these cardiovascular disorders is rising at staggering rates in most Latin American countries. ED is a symptom that mainly affects economically productive men (40–70 years of age) potentially causing major psychosocial repercussions and reduced quality of life. The management of ED in these developing countries is increasingly challenging due to poor patient education and non-adherence to the medical treatment of theses concomitant comorbidities. The financial implications of commonly prescribed medications and surgical procedures limit their use to a minority of patients. For this reason, the clinician must adopt a holistic approach in the management of this disease focusing on preventive measures based on patient education and non-surgical interventions. This review summarizes common associated risk factors of ED and outlines non-pharmacological interventions for the management of this disease.

Objective: Investigate the microbiology and incidence of drug resistance in patients undergoing TURBT and to identify independent risk factors for UTI following surgery. Material & Methods : Retrospective observational study of prospectively collected data of 199 patients who underwent TURBT in a tertiary care center in Mexico City between 2017-2019. Baseline characteristics and microbiological data (frequency of isolated bacteria and antibiotic resistance pattern) were analyzed according to the presence of UTI following surgery. Binary logistic regression analysis was performed to identify independent risk factors for UTI. Results: A preoperative positive urine culture (PUC) was present in 28 patients (14%), the most common isolated pathogens were Escherichia coli(48%), Enterococcus faecalis(24%) and Proteus mirabilis(7%). UTI was documented in 20 patients after TURBT (10%), being E. coli(45%) the most common uropathogen which was resistant to Trimethoprim/Sulfamethoxazole(60%) and Ciprofloxacin(40%). Other common isolated pathogens were E. faecalis(27%) and P. mirabilis(9%). There was significant difference in the presence of a PUC before TURBT and necrosis (p=0.001). On the multivariate analysis the PUC before TURBT was associated with UTI after TURBT (OR7.04 [95%CI 2.11-23.29]). Limitations: Retrospective study with information limited to the clinical file. Originality: There is little information about UTI after TURBT in global literature, in Mexico there is no information, being this study unique in his kind. Conclusions: The incidence of UTI after TURBT was 10%. The strongest associated risk factor for UTI after TURBT was a preoperative PUC. The most common isolated uropathogen was E. coli. Trimethoprim/Sulfamethoxazole(60%) and Ciprofloxacin(40%) were the most resistant antibiotics for E. coli.

Background:The negative impact of tobacco smoking on renal function has been widely studied. However, there is limited knowledge about the effect of smoking on pre-operative and post-operative renal function in living kidney donors. Objective:The objective of the study was to evaluate the short-and mid-term impact of smoking on donor renal function. Methods: This is a retrospective study of 308 patients who underwent living donor nephrectomy (LDN) at a tertiary referral hospital. We compared baseline characteristics as well as functional outcomes following LDN according to history of tobacco smoking. Estimated glomerular filtration rate (eGFR) was calculated with the modification of diet in renal disease equation in 6 time periods: pre-operative, 1 week, 1 month, 6 months, 12 months, and 24 months after surgery. We performed a Kaplan-Meier analysis for chronic kidney disease (CKD) outcome and binary logistic regression analysis to identify risk factors associated with CKD at 24 months of follow-up. Results: Among donors, 106 (34.4%) reported a smoking history before nephrectomy. Smoking donors had worse pre-operative eGFR than non-smokers (90 ± 26.3 mL/min/1.73m 2 vs. 96 ± 27 mL/min/1.73 m 2 , respectively; p = 0.02) and lower eGFR at 1 week (p = 0.01), 1 month (p ≤ 0.01), 6 months (p = 0.01), and 12 months (p = 0.01) after LDN. Tobacco smoking (OR 3.35, p ≤ 0.01) and age ≥ 40 years at donation (OR 6.59, p ≤ 0.01) were associated with post-operative development of CKD at 24 months after LDN. Conclusions: Living kidney donors with a tobacco smoking history had an increased risk of developing chronic kidney disease following nephrectomy. Smoking-cessation strategies should be implemented.
