NCT ID: NCT06249100 Recruiting - Renal Stone Clinical Trials

Flexible Mini Percutaneous Nephrolithotomy vs Retrograde Intra-renal Surgery

Start date: January 1, 2024
Phase: Phase 2/Phase 3
Study type: Interventional

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.

NCT ID: NCT06185387 Not yet recruiting - Renal Stone Clinical Trials

Changes Post Percutaneous Nephrolithotomy

KUB
Start date: March 1, 2024
Phase:
Study type: Observational [Patient Registry]

Using color doppler U/S, Abdominal U/S and radioisotope to evaluate changes of renal morphology, function and doppler parameters post Percutaneous nephrolithotomy

NCT ID: NCT06138704 Completed - Renal Stone Clinical Trials

Evaluation of Retrograde Intrarenal Surgery Results and Stone-free Rate in Children With Kidney Stones

Start date: January 1, 2019
Phase:
Study type: Observational [Patient Registry]

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

NCT ID: NCT06131151 Not yet recruiting - Renal Stone Clinical Trials

Comparison Between External Oblique Intercostal Block and Erector Spinae Plane Block in PCNL

Start date: November 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06110247 Active, not recruiting - Renal Stone Clinical Trials

Evaluation of Renal Oxygenation by NIRS in Pediatric Endourologic Stone Surgery

Start date: November 3, 2023
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT06101563 Recruiting - Renal Stone Clinical Trials

Duration Between Drainage and Ureteroscopic Lithotripsy

Start date: May 1, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06085794 Recruiting - Renal Stone Clinical Trials

Standard PCNL Vs Endoscopic Combined Intrarenal Surgery (ECIRS) for Complex Nephrolithiasis in Obese Patients

ECIRS
Start date: July 25, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06070714 Enrolling by invitation - Renal Stone Clinical Trials

Efficiency and Safety of Holmium Laser With Moses Technology Versus SuperPulsed Laser System With Thulium Fiber Laser on Renal Stones

Start date: September 7, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05894668 Not yet recruiting - Renal Stone Clinical Trials

Perioperative Parameter and Treatment Outcomes of ECIRS in Asia

Start date: June 1, 2023
Phase:
Study type: Observational

This is an observational, international, multicenter, cohort study, prospectively collecting clinical data registry on consecutive patients with urinary stone undergoing ECIRS.

NCT ID: NCT05833386 Recruiting - Renal Stone Clinical Trials

Effect of Preoperative Silodosin on Feasibility of Ureteral Access Sheath Insertion

Start date: October 1, 2022
Phase: N/A
Study type: Interventional

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
