Filter by:This is a randomized controlled clinical study evaluating the use of next-generation sequencing (NGS) to improve antibiotic prescribing before ureteroscopy or percutaneous nephrolithotomy.
Several studies were conducted to compare extracorporeal shockwave lithotripsy (SWL) and percutaneous nephrolithotomy (PNL) as treatment options for medium size lower caliceal high dense stones. However, no studies compared these options for non- lower polar stones. In the present study the investigators will compare mini-PNL and SWL in treatment of non- lower polar, medium size, high dense renal stones in reference to the stone free rate and safety of the procedures. Pre-operative evaluation including abdominal non-contrasted computed tomography will be performed for all patients. Patients will be randomly allocated into two equal groups and will be treated by either mini-PNL or SWL. postoperative, patients will be followed by regularly for 3 months. the outcome of the procedures will be evaluated and compared between groups.
The investigators aim to investigate the effect of peritubal local anesthetic infiltration on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy.
The primary objective is to evaluate whether one-phase nephrographic CT (experimental) is sufficient to detect urothelial cell carcinoma in patients with hematuria compared to the traditional four-phase CT (control).
- The primary aim is to study the natural history of single-calyx asymptomatic nonobstructing stone disease. - The Secondary aim is to determine the predictors of the need for intervention and of cure in such population.
The impact of different frequencies on pattern of disintegration of renal stones
This prospective pre and post-quasi-descriptive single group interventional study will be done at urology and nephrology center -Mansoura University during the year 2019, for a 3-month duration, starting 1-2-2019 till 1-4-2019 after approval of IRB (Institutional Review Board) code no R/18.03.103 on 5/5/2018, Mansoura Faculty of Medicine. correlating Basic hemodynamics with noninvasive cardiac output for diagnostic reliability during percutaneous nephrolithotomy hidden bleeding under spinal anesthesia
The investigators aim at this study to prospectively assess procedure-related outcomes after RIRS for renal calculi less than 20 mm, including stone free rate (SFR), predictors of successful outcome, complications types/rate, readmission rate and the need of auxiliary procedures. In addition, patient-reported outcomes after this modality of intervention are going to be assessed.
Having the advantages of being minimally invasive and simple, extracorporeal shock wave lithotripsy (SWL) remains one of the treatment options for renal stones less than 2cm. Although SWL is the most minimally invasive surgical approach for stone, there are still some concern about its short and long term side effect. While, there are some evidences that SWL might lead to increase in new onset hypertension, investigator's recent study suggested it might also cause worsening of blood pressure control in patient with known hypertension. Therefore, further studies are needed to confirm the initial finding. This study recruits patients who have hypertension and are currently diagnosed to have renal stone and planned for SWL, in order to to investigate the effect of SWL on blood pressure control. After informed consent and background information have been obtained, patients will be randomized to either have routine SWL (treatment arm) or 6 months later (control arm). Group 1 patients will have blood pressure monitored for one day at home by an handy automated blood pressure measuring machine before SWL and 6 months after SWL. Group 2 patients will have blood pressure monitoring immediately and then 6 months later, just prior to the SWL.
The purpose of this research study is to compare how well two treatments work for removing kidney stones. The two study groups include ureteroscopy with long/short pulse lithotripsy to remove kidney stones. Both of these options are considered standard of care and are used currently in surgery.
