Filter by: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.
Rcompare high-energy versus low-energy laser settings in renal stone lithotripsy using low power machines) Holmium YAG 30 watts, examining their respective advantages, limitations, and overall efficacy.
The use of flexible ureteroscopy and minimally-invasive percutaneous techniques, which utilize smaller tract sizes, has been established as a way to decrease the invasiveness of procedures and improve patient outcomes compared to conventional percutaneous nephrolithotomy (PCNL) and flexible mini-PCNL has emerged as a novel technique previously first as an auxiliary procedure and then as a standalone technique. This study aims to assess the feasibility and effectiveness of flexible nephoscopy in improving stone clearance compared to standard retrograde intrarenal surgery using a flexible ureteroscope.
Using color doppler U/S, Abdominal U/S and radioisotope to evaluate changes of renal morphology, function and doppler parameters post Percutaneous nephrolithotomy
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
The aim of the study is to compare the post-operative analgesic effect of USG unilateral External oblique intercostal (EOI) block with Erector spinae plane block (ESPB) for after percutaneous Nephrolithotomy with a hypothesis that both External oblique intercostal fascial plane block and Erector spinae plane block are effective in providing postoperative analgesia.
The study aims to compare renal oxygenation levels in retrograde intrarenal surgery (RIRS) and ureteroscopy (URS) procedures with a control group. Additionally, it seeks to determine if there is a connection between postoperative infection parameters and intraoperative renal oxygenation measurements.
This study will be conducted to compare early (one week) versus delayed (2-4 weeks) definitive ureteroscopic lithotripsy after initial drainage for obstructing ureteral or renal stones associated with infection.
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.
This is a prospective randomized controlled trial designed to assess the efficacy and safety of Lumenis® Pulse™ P120H holmium laser system with the Moses technology (holmium laser with pulse modulation) versus the Soltive™ SuperPulsed Laser System with the thulium fiber laser (thulium fiber laser), in dusting of renal stones during ureteroscopy with laser lithotripsy. 310 participants will be enrolled across 5 research sites.
