Filter by:Malignant ureteral obstruction (MUO) is an extrinsic ureteral obstruction caused by malignant diseases. This study aim to compare tandem 6 Fr Percuflex™ stents and single large-caliber 8Fr silicone stent in patients with MUO. The primary endpoint is stent failure rate. The secondary endpoints are patient comfort, quality of life and overall survival.
The goal of this retrospective study is to analyse the outcomes of Robot-Assisted Pyeloplasty in participants younger than 5 years old: - indication criteria - clinical symptoms - operating time - length of stay - complications - follow-up
This research study will compare two procedures commonly used to treat urinary obstruction due to cancer. Sometimes cancer blocks one or both ureters (narrow tubes in the body that carry urine from the kidneys to the bladder). When these ureters become blocked, the body can no longer properly drain urine. This blocking of the ureters is called urinary obstruction, which can lead to kidney problems, infection, and pain. Treatment options for urinary obstruction include ureteral stent placement and percutaneous nephrostomy tube placement. Both treatment options require a doctor to place soft tubes (like a catheter) inside the body to help the ureters properly drain urine. These two treatment options have different success rates, risks, and effects on quality of life. By doing this study, researchers hope to learn which treatment option is best for individuals who develop urinary obstruction because of cancer. Participation in this research will last about 3 months.
In this prospective randomized controlled study, it is aimed to investigate the effects of guidewire advanced through a previously placed double j stent on postoperative complications, operation time and efficacy.
To evaluate the role of both primary and deferred URS in the management of calculus anuria concerning the feasibility, clinical outcome, and cost-effectiveness in children in a comparative study
To investigate the effectiveness of percutaneous nephrostomy catheter placement versus retrograde double J catheter placement in patients with symptoms of obstructive kidney disease (with either infection and/or pain and/or kidney function deterioration) caused by urolithiasis.
A multi-center global registry to obtain post-market safety and efficacy data on Boston Scientific Ureteral and Urinary Diversion Stents
This study will be conducted to compare the efficacy and safety of Trospium chloride versus Tamsulosin for treatment of ureteral stent related symptoms.
