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).
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.
Retrograde intrarenal surgery (RIRS) with flexible ureteroscopy is based on video monitoring of urinary tract during operation. Therefore, shaking vision on monitor can bother surgeons and make them tired. This can lead in tissue injury from lasing. The purpose of this study is to investigate the stability of monitoring of surgical field which is assessed by surgeon.
The purpose of this study is to assess whether one of two ureteral access sheaths is safer for patients undergoing ureteroscopy. Both sheaths are FDA approved devices and commercially available. The investigators will compare the ability of sheaths to access the kidney through the ureter and will compare damage done to the ureter after completion of the procedure. Access sheaths are standard of care for this procedure; this study seeks to optimize outcomes for patients. Patients undergoing ureteroscopy who do not have ureteral stents in place and who have not had an ipsilateral procedure within 90 days will be recruited and consented.
The objective of the this study was to examine the amount and duration of tea consumption in relation to the risk of renal stone disease.
Prospectively randomized study in patients with renal pelvic stones who are candidate to standard PCNL procedure. One to one, controlled clinical trial. Patients will be randomly allocated into two groups, 20 patients in each group. Group A will be scheduled to receive routine standard PCNL. Group B will be scheduled to receive Robot assisted pyelolethotomy.
