Filter by:Urinary tract obstruction is a serious health problem due to kidney damage. Relative renal function has an important role in the treatment of obstructed kidneys. Nephrectomy can be recommended when the relative renal function is 10% or less in radionuclide examinations. Recently, however, nephron sparing approaches have come to the fore. This indicated the need to evaluate the possibility of recovering the function of the kidney before nephrectomy. The aim of this study is to compare relative functions of obstructed kidneys in technetium 99m dimercaptosuccinic acid scintigraphy (DMSA) before and 2 weeks after nephrostomy tube.
The investigators propose a pilot clinical trial on the use of perioperative pregabalin in order to decrease ureteral stent related symptoms and decrease opioid usage after ureteroscopy with stent placement. Patients undergoing ureteroscopy with stent placement will receive a single dose of 300 mg pregabalin PO in the preoperative area. This work will assess safety and feasibility of studying this regimen at our institution, with the aim of performing a randomized, placebo-controlled, double-blinded study in the future.
The purpose of this study is to evaluate the efficacy and safety of DCR-PHXC in Children and Adults with Primary Hyperoxaluria Type 1 (PH1) and Primary Hyperoxaluria Type 2 (PH2)
Obesity is not a homogeneous condition and that the regional distribution of adipose tissue is important to understanding the relation of obesity to disturbances in glucose and lipid metabolism. Central abdominal fat is composed of abdominal subcutaneous fat and visceral fat. Regional distribution appears to be an important indicator for metabolic alterations since an inconstant correlation between body mass index (BMI) and these disturbances have been found. Visceral obesity is associated with increased adipocytokine production, proinflammatory activity, deterioration of insulin sensitivity, increased risk of developing diabetes, "high-triglyceride/low-HDL cholesterol dyslipidemia," hypertension and atherosclerosis. It might be more precise to divide central abdominal fat into subcutaneous(S) and visceral (V) fat surface area and volume and even ratio (S/V); risk factors for cardiovascular disease, particularly those related to glucose and lipid metabolism and hypertension, being>0.4; with evaluation of visceral fat functionality by visceral adiposity index (VAI) with integration with lipid profile. Adding bladder wall thickness with perivesical fat as a factor may impair bladder function and contribute to dysregulation. The data on the association between central adiposity with OAB symptoms and Urodynamics is not mature.
Benign complex cystic and vascular adrenal tumors comprise a group of lesions characterized by significant rarity. But, their detection is increasing due to improved radiologic imaging techniques. Nevertheless, they are still conflicting with other lesions. the investigators reviewed their experience with complex cystic benign adrenal tumors in adults, review previous reports to determine the appropriate diagnosis and management of these tumors.
To evaluate the safety and efficacy of LithoVue ureteroscope system in Chinese population.
1. The muscle relaxants can improve the conditions of laryngeal mask incubation and reduce the related complications (such as laryngeal spasm and postoperative throat pain) 2. The dosages of muscle relaxants used in various researches vary greatly. 3. We are planning use the most classical method for determining the ED50 or half effective concentration of cis-atracurium using sequential method, which is also called " up and down method" and " ladder method".
The investigators want to verify whether the surgical outcome of vessel-sparing anastomotic repair in isolated short bulbar urethral strictures is not inferior to the surgical outcome of transecting anastomotic repair. Furthermore, the investigators compare the functional outcome of both techniques verifying if there is less erectile dysfunction after vessel-sparing anastomotic repair than after transecting anastomotic repair.
Our hypothesis is: the nutritional supplement Ocoxin-viusid improves the quality of life of patients, including a better tolerance to neoadjuvant chemotherapy.
The investigators attend to conduct a prospective randomized study to assess safety and efficacy of trigonal-involved vs. trigonal-sparing botox injection technique, quality of life measurement and post-injection anticholinergics use efficacy. Assessing safety by identification of side effects like constipation, urine retention....etc. efficacy is measured using Over Active Bladder Symptoms Score(OABSS) and urodynamics measures after 6 months follow up.
