Filter by:This is a prospective case series study. To compare urine sample of recurrent stone-formers and non-stone former by multiomics approach to identify potential markers for stone recurrence.
Urosepsis is one of major cause of the overall sepsis leading to high morbidity and mortality, which commonly resulted from urinary tract calculi. The investigator aim to identified the incidence and risk factors of urosepsis in the patients with urinary tract calculi underwent surgical intervention in tertiary-care university hospital.
This is a prospective data registry to assess the treatment outcomes and complications of different treatment approaches for different surgical treatment of urolithiasis in our hospital clusters.
The minimally-invasive extracorporeal shockwave lithotripsy (ESWL) procedure is generally considered the best first-line treatment option for most adults and children with nephrolithiasis, especially when the calculi are smaller than 2 cm in size. Despite some promising results, few clinical trials have assessed the impact of furosemide on the outcome of ESWL. This study seeks to determine the effect of furosemide on ESWL outcomes when treating renal and ureteral calculi, hypothesizing that it will result in better outcomes for patients. The present double-blind, randomized clinical trial includes 500 adults aged 18-60 years referring to the ESWL Clinic of Shahid Faghihi Hospital. Using block randomization, the patients are randomly assigned to one of two groups. All patients are to receive sedation with intravenous midazolam and 1000 ml of normal saline 30 minutes before ESWL. The only difference between the groups is that in the furosemide group, 40 mg of furosemide is added to the normal saline in the drug preparation room before administration. All patients are kept under heart monitoring and pulse oximetry until recovery. Pain will be checked for all participants via a telephone interview 24 hours later. The outcomes and possible side effects of ESWL will be evaluated for all patients after two and twelve weeks.
The aim of this trial is to compare the efficacy and safety of flexible ureteroscope with intelligent control of renal pelvic pressure (FURL-ICP) and traditional flexible ureteroscope(f-URL) in the treatment of upper urinary stones ≤ 2cm in diameter. It is designed as a multicenter, parallel randomized controlled trial with two arms. At least 449 patients with upper urinary stones ≤ 2cm in diameter will be invited to participant in this study. Patients will be assigned to intervention group (FURL-ICP group) or control group (f-URL) by a simple random sampling technique with a rate of 1:1. The baseline of participants include demographic data, urine analysis, blood cell analysis, blood biochemical analysis, and urinary computer tomography (CT) with a slice thickness of 2mm. The primary outcomes are postoperative stone-free rate (SFR) of one month by CT scan and postoperative fever rate (body temperature > 38.5 ℃ within 3 days after operation). Secondary outcomes include operating time, degree of ureteral injury, SFR of one day.
The investigators aim to compare the performance of the Super Pulse Thulium fiber laser (SP TFL) with that of the standard Holmium: Yttrium-Aluminium-Garnet (Ho:YAG) laser. The investigators hypothesize that the electronically-modulated laser diodes, of the TFL offers the most comprehensive and flexible range of laser parameters among laser lithotripters leading to more efficient (4 times more) and effective stone dusting resulting in production of finer dust particles obviating the need for postoperative ureteric stenting which remains a major source of patient discomfort.
To compare intraoperative as well as postoperative outcomes of SOLTIVE Thulium laser compared to Ho:YAG laser for the treatment of urolithiasis. The hypothesis is that utilizing the SOLTIVE Thulium laser for the treatment of urolithiasis will result in a more efficient procedure, with comparable stone free rate to that of Holmium laser and subjective improvement in physician satisfaction.
In this study, the investigators aim to evaluate the intervention preferences of patients with obstructive urinary stones who are suitable for operation during the COVID-19 pandemic. The secondary aim is to compare and evaluate the preferences compared to the pre-pandemic period and to gain a perspective on how the decision-making process has changed from the patient's point of view. Thus, by trying to understand how the COVID-19 epidemic affects the treatment choice decisions of patients, the investigators aim to determine how the state of anxiety changes these preferences.
The femur or thigh bone is the strongest and longest bone of the body and about 45 cm long in an average man that means approximately one fourth of the height of individual. It has upper end, lower end and a cylindrical shaft. Upper end consists of head, neck. The neck is about 5 cm long, connects the head to the shaft and is directed upward, medially and slightly forward and making an angle about 125 with shaft but the angle is wider in children. The neck-shaft angle (NSA ) is defined as the angle formed by the neck axis and long axis of the shaft of femur.The knowledge of the neck shaft angle is valuable in the diagnosis and treatment of fracture of upper end of femur. The aim of the study is : 1. to evaluate the normal values of femoral neck-shaft angle 2. to detect factors that may affect this angle as age, and sex, in Egyptian adults from Sohag.
The purpose of the study is to identify bacterial and fungal microbiome associated with calcium oxalate (CO) urolithiasis and renal cell carcinoma (RCC).
