The prevalence of asymptomatic hydronephrosis, now detected by ultrasonography, has increased. However, definitive management guidelines for the management of congenital hydronephrosis have not been established. The Japanese Society of Pediatric Urology created a "medical management guide" based on new findings for physicians practicing pediatric urology. We developed a medical management guide focused on congenital hydronephrosis caused by ureteropelvic junction obstruction. This medical management guide consists of the definition, pathophysiology, epidemiology, diagnosis, classification, treatment using a clinical management algorithm of hydronephrosis and the long-term course of the disease. The aim of hydronephrosis management is to determine whether surgery should be carried out to avoid renal dysfunction, as there is a possibility for improvement without intervention. Ultrasonography is essential to make treatment decisions. Management is determined by a comprehensive assessment, including the degree of hydronephrosis, anterior-posterior diameter of the renal pelvis and, if necessary, a nuclear medicine evaluation of the status of urine drainage and renal function.
Aim : Erectile dysfunction (ED) is common in patients with diabetes mellitus (DM) as well as those undergoing hemodialysis (HD). The purpose of this study is to investigate the frequency and severity of ED in HD patients with DM and those without DM. In addition, we examined the relationship between erectile function and several risk factors, including presence of DM and hemoglobin A1c levels in HD patients.Methods : This study involved 180 patients on HD, including 66 HD patients with DM (DM-HD) and 114 patients without DM (non-DM-HD). We evaluated erectile function using an abridged fiveitem version of the international index of erectile function (IIEF-5). Logistic regression analysis was used to investigate the relationship between presence of ED and several risk factors. Results : The total score of IIEF-5 in DM-HD patients (9.5 ± 4.2) was significantly lower than in non-DM-HD patients (13.5 ± 5.7). The prevalence of severe ED was 42.4% and 18.4% in DM-HD patients and non-DM-HD patients, respectively. Age, cardiovascular disease history, and DM were identified as independent risk factors for the presence of ED. Furthermore, age and elevated hemoglobin A1c levels were identified as independent risk factors for the presence of severe ED. Conclusion : DM-HD patients are more likely to have ED, and particularly severe forms of ED, than non-DM-HD patients. DM and elevated hemoglobin A1c levels were associated with the presence of ED or severe ED, respectively. Aging was identified as an independent factor in both ED and severe ED.
The present study showed that the early removal of the urethral catheter, and preoperative dementia and/or delirium had significant correlations with POUR. The femoral neck fractures and the surgical procedure used for the hip surgery do not induce damage to the bladder and nerve system related to the voiding function, and the voiding function in all of the patients recovered after short-term intermittent catheterization. Physicians should not place permanent indwelling urethral catheters without carrying out urological assessments.
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.
