Filter by: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.
Guidelines for endourological procedures during COVID-19 have suggested deferring all elective procedures, while obstructed/ infected stones should undergo urgent decompression. At our centre, screening protocols were implemented with prioritization strategies so that elective care could safely continue at deescalated rates. COVID or septic patients underwent emergency decompression, while non-COVID and non-septic patients underwent primary ureteroscopy (URS) or retrograde intrarenal surgery (RIRS). We aim to report our experience with endourological surgery for stone disease during COVID-19.
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.
Urinary calculi have become a global public health problem, which brings a huge economic burden to society and individuals. The pathogenesis of urinary calculi is not completely clear. Supersaturation of urinary components is a necessary condition for the formation of urinary calculi. The causes of stone formation are closely related to diet, drugs, metabolic disorders, basic diseases, genetic factors, environment and so on. Diet essentially determines the composition of urine, which affects the formation of urinary calculi. The effect of dietary phosphorus intake on stones is not clear. There is a lack of data to support dietary phosphorus as an influencing factor of stone formation. Phosphorus is present in most foods. 24h urine composition analysis is of great value in predicting the occurrence and composition of urinary calculi. However, due to the interaction between urine components, a single urine component can not well predict the occurrence of stones. Therefore, the researchers introduced the relative supersaturation of common stone components in urine to predict the incidence of stones. Therefore, we want to give healthy adults a diet with different phosphorus content for a period of time to clarify the effect of phosphorus in the diet on 24h urine composition level and urine relative supersaturation, so as to further explore the relationship between dietary phosphorus and the incidence of urinary calculi. To provide more clear recommendations for early prevention of urinary calculi, and provide more evidence for clinical decision-making, thereby reducing the incidence rate of urinary calculi.
This is an observation, single site-study with one study visit during which all data and samples will be collected. Study participants will be asked to provide blood, urine, and fecal samples so that the investigators may study the differences in the gut microbiota, vitamin K2 levels, and other parameters between participants who form kidney stones and those who do not.
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 obtain post-market safety and efficacy data for FlexivaTM Pulse High Power Single-Use Laser Fibers during lithotripsy and soft tissue procedure of holmium laser enucleation of the prostate (HoLEP).
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.
