Summary: This study aimed to determine the effects of virtual reality and stress ball interventions on procedure-related fear, anxiety, and patient satisfaction in patients undergoing ureterorenoscopy. The study is a prospective, randomized controlled clinical trial. The sample size was calculated to ensure sufficient statistical power to detect an effect size of Cohen's f = 0.333, considering α = 0.05, po...

Summary: The purpose of this research is to evaluate if corticosteroid (prednisone) after ureteroscopy and placement of the stent will help alleviate postoperative pain control in addition to other normal postoperative pain medications

Summary: The goal of this prospective, multicenter, randomized controlled trial is to objectively evaluate the clinical efficacy and safety differences between superpulse thulium fiber laser (sTFL) and holmium:YAG laser (Ho:YAG) in flexible ureteroscopy (FURS) lithotripsy in adult patients aged 18-70 years with kidney stones and/or upper ureteral stones (6-20mm). The main questions it aims to answer are: D...

Summary: Comparison of routine postoperative stenting versus no stenting after ureterorenoscopy for ureteral stones to assess the necessity and impact on complication risk.

Summary: This study aims to compare the efficacy and safety of two modern, minimally invasive surgical techniques for the removal of kidney stones: Mini-Percutaneous Nephrolithotomy (Mini-PCNL) and Flexible Ureteroscopy (FURS) with Flexible and navigable suction sheath The primary objective is to determine which procedure results in a higher stone-free rate, as measured by post-operative imaging. Secondary...

Summary: This is a multicenter prospective trial with randomized and observational cohorts assessing patient-reported outcomes and unplanned healthcare utilization following ureteroscopic treatment of renal and ureteral stones, with placement versus omission of a ureteral stent. Eligible participants in the randomization trial will be randomized to ureteroscopy with stent placement or stent omission. Eligi...

Summary: Double-J (DJ) stents are commonly inserted after ureteroscopy. There are several complications associated with the presence of DJ stent: urinary tract infection, stent encrustation, stent migration, and stent-related symptoms (SRS). SRS occur in up to 80% of patients and include pain, hematuria, and dysuria, all of which negatively impact the patient's quality of life. Physicians proposed the dist...

Summary: Ureteroscopy has been considered the best approach when treating renal stones smaller than 2 cm. This procedure is usually performed together with ureteral access sheaths, which helps protect the ureter mucosa and lowers intrarenal pressure. Recently, a new vacuum-assisted ureteral access sheath called ClearPetra has entered US market and allows for continuous stone fragmentation and aspiration. B...

Summary: To compare the efficacy, safety, success rate, operative time, and cost-effectiveness of flexible ureteroscopy versus semirigid ureteroscopy in the management of upper ureteric stones smaller than 2 cm. The investigators' main concern in this study is Upper third ureteric stones to determine which cases can be treated with Semi-Rigid Ureteroscopy, and which one needs flexible ureteroscopy. This de...

Summary: In view of the positive results of the numerous studies conducted on forced diuresis after extra-corporeal lithotripsy, the investigators chose to evaluate forced diuresis by injection of Furosemide associated with intravenous hydration, which has never before been the subject of a specific analysis.

Summary: The aim of this study is to evaluate and assess the outcomes of flexible ureteroscopy (FURS) with flexible and navigable suction UAS (FANS) in the treatment of lower calyceal stones.

Summary: This study is designed as an open-label, single-arm, single-center, phase II clinical trial, aiming to evaluate the efficacy of nephron-sparing treatment combining Tislelizumab and Nab-Paclitaxel for HER-2 expressing renal pelvic cancer (RPC) . Patients enrolled will receive 2-3 cycles of Tislelizumab in combination with Nab-Paclitaxel every 3 weeks and then undergo evaluation. Patients who achiev...
