• Phosphodiesterase 5 inhibitors used in the clinical setting can significantly improve LUTS secondary to BPH, erectile function and quality of life. Maximum urinary flow improvement is not statistically significant. • Future research should focus on pathophysiological principles and cost analysis.
Objective To investigate the association between the severity of erectile dysfunction (ED) and coronary artery disease (CAD) in men undergoing coronary angiography for angina or acute myocardial infarct (AMI).Material and Methods We studied 132 males who underwent coronary angiography for first time between January and November 2010. ED severity was assessed by the international index of erectile function (IIEF-5) and CAD severity was assessed by the Syntax score. Patients with CAD (cases) and without CAD (controls) had their IIEF-5 compared. In the group with CAD, their IIEF-5 scores were compared to their Syntax score results.Results We identified 86 patients with and 46 without CAD. The IIEF-5 score of the group without CAD (22.6±0.8) was significantly higher than the group with CAD (12.5±0.5; p<0.0001). In patients without ED, the Syntax score average was 6.3±3.5, while those with moderate or severe ED had a mean Syntax score of 39.0±11.1. After adjustment, ED was independently associated to CAD, with an odds ratio of 40.6 (CI 95%, 14.3-115.3, p<0.0001). The accuracy of the logistic model to correctly identify presence or absence of CAD was 87%, with 92% sensitivity and 78% specificity. The average time that ED was present in patients with CAD was 38.8±2.3 months before coronary symptoms, about twice as high as patients without CAD (18.0±5.1 months).Conclusions ED severity is strongly and independently correlated with CAD complexity, as assessed by the Syntax score in patients undergoing coronariography for evaluation of new onset coronary symptoms.
Kidney cancer is a common urologic malignancy with either laparoscopic (LPN) or robotic partial nephrectomy as therapeutic options of choice for localized tumors. However, renal resection and suturing are challenging steps of the procedure that can lead to complications such as prolonged warm ischemia, bleeding, and urinary fistulas. LPN with a diode laser is an efficient technique due to its cutting and/or coagulation attributes. Surprisingly, key laser features such as wavelength and power remain undefined. Using a large porcine model, we evaluated the laser range of wavelength and power in a clamp-free LPN and compared it to the established gold-standard LPN technique (i.e., cold-cutting and suturing). By analyzing surgery duration, bleeding, presence of urine leak, tissue damage related to the resected renal fragment and the remaining organ, hemoglobin levels, and renal function, we show that an optimized experimental diode laser clamp-free LPN (wavelength, 980 nm; power, 15 W) had shorter surgery time with less bleeding, and better postoperative renal function recovery when compared to the well-established technique. Together, our data indicate that partial nephrectomy with a diode laser clamp-free LPN technique is an improved alternative to the gold-standard technique. Therefore, translational clinical trials towards human patient applications are readily feasible.
BackgroundMinimally invasive surgeries are increasingly common as the first option for most urological diseases. However, laparoscopic techniques are difficult to master, especially for surgeons who were not trained during their residency programs. Therefore, postgraduate courses are important for such matters. This study aims to evaluate the results of postgraduate courses in minimally invasive urological surgery.MethodsA specific questionnaire was used to evaluate the impact of the course on urologists’ professional activities. The questionnaire also evaluated demographic data and previous surgical experience. The postgraduate course was divided into 10 monthly modules, each one with 36 hours of activities, from March to December. All students of the laparoscopic postgraduate course from the last five years were enrolled in the study.ResultsForty-one students were included in the study. Thirty-nine students were male (95.1%), and the mean age was 39.5 years (range, 30–60 years). Students from all regions of the country were enrolled. Thirty (73.2%) students had minor laparoscopic experience. All students improved their laparoscopic skills and were able to include new procedures in their daily surgical practice. Eleven students (26.8%) had no laparoscopic experience, and all of them started to perform laparoscopic procedures. The median level of impact on professional life was 75 points (range, 0–100 points).ConclusionsThe postgraduate course is an appropriate way to acquire urological laparoscopic skills. The annual course allowed improvement and initiation of laparoscopic procedures, which significantly impacted urologists’ daily activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
