NCT07155005
The goal of this clinical trial is to evaluate the effectiveness and safety of Steerable Ureteroscopic Renal Evacuation (SURE) with the CVAC System versus other commonly used renal-stone interventions.
NCT07211555
This study is being done to evaluate a new robotic system that helps urologists more precisely reach the kidney during surgery to remove large kidney stones. The procedure, called percutaneous nephrolithotomy (PCNL), is typically used for people who have large or difficult-to-remove kidney stones. Traditionally, many urologists rely on radiologists to place a tube into the kidney before surgery. This can cause delays, require multiple procedures, and increase costs. The robotic system being studied - called LARC - is designed to help the urologist safely and accurately guide a needle directly into the kidney during the surgery, without needing a separate procedure beforehand. The robot uses live X-ray images to help align the instruments. Although parts of the robot have been approved by the U.S. FDA, the version used in this study is still investigational and not yet approved for this specific purpose. The study will take place at AdventHealth Celebration and include up to 45 adult patients who are scheduled for PCNL surgery. Participants will be followed for up to 1 month after surgery, and doctors will look at outcomes such as the success of the procedure, the number of kidney stones removed, complications, time in surgery, and radiation exposure. This research may help make kidney stone surgery safer, faster, and more effective in the future.
NCT07101809
The goal of this clinical trial is to compare Steerable Ureteroscopic Renal Evacuation (SURE) using the CVAC System and standard ureteroscopy (URS) with laser lithotripsy for the treatment of urolithiasis. This is a prospective, randomized (1:1), multi-center study.
NCT06422312
This study will compare the time required for a cystoscopy procedure in adult participants using the Redpine® Rflex endo(trademark) High-Definition Cystoscope or the site's standard of care reusable flexible cystoscope in participants requiring urethral stent removal.
NCT06814834
This study aimed to compare oral dissolution therapy (ODT), extracorporeal shock wave lithotripsy (ESWL), and a combination of ESWL and ODT as noninvasive modalities for treating small and medium-sized renal radiolucent.
NCT06681116
We assessed the effect of structured nano-water in the prevention of recurrent stone formation in patients with recurrent calcium oxalate stones and hypercalciuria.
NCT06122129
The aim of this study is to evaluate the flexible ureteroscope (FURS) technique with and without ureteral access sheath (UAS).
NCT06138704
There is a global increase in the prevalence of urolithiasis in children attributed to lifestyle changes, dietary habits, climate changes, childhood obesity, and the wider availability of ultrasonography. The rising incidence of the disease with its recurrent nature emphasizes the need for minimally invasive therapeutic options. Patients in whom RIRS has been performed in the last four years with increasing experience will be presented, and complications, stone-free rates, and technical details will be discussed. This retrospective Cohort study included children who underwent RIRS. Medical history, serum electrolytes, midstream urine culture, urinalysis, serum creatinine, complete blood count, and coagulation assessments were performed preoperatively. Ultrasonography (USG) was performed three months, 6 months, and 1 year after the procedures to evaluate stone recurrence and hydronephrosis. The investigators analyzed the stone-free rate ,complications, and the conversion to open procedure
NCT06085794
Primary aim: comparing the efficacy of standard PCNL and endoscopic combined intrarenal surgery (ECIRS) in the Galdakao-modified Supine Valdivia (GMSV) position in a single session for the treatment of complex nephrolithiasis in obese patients. Secondary aim: comparing safety and complications of standard PCNL and ECIRS in the GMSV.
NCT05833386
The ureteral access sheath (UAS) is an ancillary device widely used by urologists to facilitate fast, repeatable, and safe access to ureters and collecting systems; improve visibility; reduce the risk of infection by reducing intrarenal pressure; and protect ureters and scopes when extracting multiple stones during surgery. Insertion of ureteric access sheath may be difficult due to tight ureter, so sometimes preoperative stenting might be needed. Silodosin is an α1A adrenoceptor with high affinity and selectivity for the ureteric muscle, which may reduce ureteral spasm. Oral a1-blockers can reduce intraureteral pressure, and may reduce maximal ureteral access sheath insertion force.¹ Preoperative silodosin protects against significant ureteral injury related to UAS insertion during fURS and decreases postoperative pain level. Silodosin premedication might be an effective and safe technique to replace prestenting.²
NCT05697341
Nephrolithiasis is the third most common disease of the urinary tract. As minimally invasive technologies develop, shock wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotomy (PCNL) are different surgeries to treat renal stones. Aim of the Study is to compare results, safety and outcome of Ultra mini PCNL versus stented extracorporeal shock wave lithotripsy (SWL) for the management of renal calculi from 10 - 20 mm. Patients were randomized to either Ultra-Mini-Percutaneous nephrolithotomy group or stented SWL group via the closed envelope method. Patient data was collected preoperatively, immediately postoperatively and 2 and 4 weeks postoperatively to assess operative time, hospital stay, complications regarding fever, hematuria and need for blood transfusion, residual stones and need for retreatment.
NCT05648877
Role Of Retrograde Intrarenal Surgery In Management Of Renal Stones: Single Center Experience
NCT04077359
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).
NCT05197088
Aim is to study if 1 week of pre operative tamsulosin would enable easier insertion of ureteral access sheath in primary retrograde intrarenal surgery for renal stone disease
NCT03373617
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.
NCT04578795
To study the Effectiveness of single use flexible Ureteroscopes in treatment of renal stones
NCT03939325
The impact of different frequencies on pattern of disintegration of renal stones
NCT03763539
Ultraslow full-power SWL versus slow power-ramping SWL in stones with high attenuation value
NCT02786446
We want to compare the effect of lignocaine 2 % gel, Naproxen sodium and their combination on the pain control during extracorporial shock wave lithotripsy for renal stones.
NCT02037906
Research Problem: Shock wave lithotripsy (SWL) dramatically changed the management of renal and ureteral calculus disease. In vitro studies suggest that progressive increase in lithotripter energy output voltage could produce the best overall stone comminution in comparison with constant or deescalating energy output. However, it is possible that the beneficial impact of slow rate SWL on comminution of stones and stone free rates has masked any marginal benefits for energy output escalation. The Escalating SW method adds the benefit of less renal tissue injury. Research Significance:The present study will signifies and evaluates the stone free rates of three groups of patients with renal stones treated with different SWL energy outputs (Escalating, Constant and Reduction energy output). Research Objectives: The aim of this research project is to study the effect of dose adjustment strategies on success rate of Shock Wave Lithotripsy in the clinical setting and to optimize the conditions for successful Shock Wave Lithotripsy. Research Methodology: This clinical trial will be conducted at a tertiary care university hospital. 150 patients referred to the Shock wave lithotripsy unit will be evaluated for eligibility to be randomized into three groups (Dose Escalation, Dose reduction and constant dose). Parameter of the three groups will be compared to detect the treatment difference.
