Active Surveillance Versus Adjuvant Intravesical Chemotherapy in Liquid Biopsy-Defined Low-Shedding Intermediate-Risk NMIBC

This trial is exploring whether some patients with intermediate-risk non-muscle-invasive bladder cancer can avoid additional chemotherapy after tumor removal if their liquid biopsy test before surgery is negative. For patients, this could mean fewer side effects and less time spent on treatment without compromising safety. The study is enrolling 670 patients in China to better understand when active surveillance might be a safe option.

Comparison of New SUREcore Biopsy of Needle to Standard of Care During Transperineal Prostate Biopsies

This study is testing a new type of biopsy needle designed to improve the quality of tissue samples taken during prostate biopsies. Better samples can help doctors detect prostate cancer more accurately and understand its characteristics, which may lead to better-informed treatment decisions. The trial is currently recruiting about 50 men in the United States.

Use of Sildenafil for Treatment of Urinary Incontinence

This Phase 1 trial is investigating whether sildenafil, a medication commonly used for other conditions, can help strengthen pelvic floor muscles and reduce urinary leakage. If successful, it could offer a new approach to managing urinary incontinence. The study is recruiting a small group of 24 participants at a single site in the United States.

Transcutaneous Tibial Nerve Stimulation for Urinary Incontinence After Radical Prostatectomy

This study is testing a non-invasive nerve stimulation treatment combined with pelvic floor exercises to help men regain bladder control after prostate surgery. This approach could improve quality of life by reducing urinary leakage without the need for more invasive treatments. The trial is recruiting 104 participants in Turkey.

Nebulized Glubran 2-Assisted Tubeless PCNL Versus Conventional PCNL

This trial compares two surgical methods for removing medium-sized kidney stones, focusing on whether a new sealant technique can reduce pain, bleeding, and hospital stay after surgery. For patients, this could mean a faster, more comfortable recovery. The study plans to enroll 100 participants in Egypt.
