Replacing Invasive Cystoscopy With Urine Testing for Non-muscle Invasive Bladder Cancer Surveillance

This Phase 2 study is exploring whether urine tests can replace the need for cystoscopy, an invasive procedure used to monitor non-muscle-invasive bladder cancer. For patients, this could mean fewer uncomfortable and invasive exams while still keeping a close watch on cancer status. The trial is currently recruiting 240 participants across eight locations in the United States.

Comparison of Radical Prostatectomy Performed by Robot-assisted Laparoscopy or Conventional Laparoscopy or by Laparotomy

This study compares three surgical techniques for prostate cancer removal to determine which method best preserves urinary function after surgery. Maintaining urinary control is important for quality of life, so the results may help patients and doctors choose the surgery that leads to better recovery. The trial is recruiting 2,000 patients in France.

Efficacy of Intracavernosal Xeomin With Tadalafil for Mild-Moderate Erectile Dysfunction: A Randomized Crossover Pilot Study

This Phase 2 trial is testing a new combination treatment for men with mild to moderate erectile dysfunction who may not respond well to oral medications alone. By combining an injection called Xeomin with tadalafil taken as needed, the study aims to offer an additional option for improving erectile function. The trial plans to enroll 30 participants and is not yet recruiting.

Relief Efficacy of Lidocaine Versus Morphine for Acute Renal Colic in the Emergency Department

This study compares lidocaine and morphine for relieving the intense pain caused by kidney stones in emergency settings. If lidocaine proves effective, it may provide a pain relief choice that reduces the use of opioids and their related risks. The trial plans to enroll 250 patients and focuses on improving pain management for people experiencing kidney stone attacks.

Brain Activity Among Children With Overactive Bladder and Daytime Urinary Incontinence and Healthy Children

This trial looks at a non-drug treatment called sacral transcutaneous electrical nerve stimulation (TENS) for children who have overactive bladder and daytime wetting. By studying brain activity before and after 10 weeks of treatment, researchers hope to understand how this therapy can improve bladder control. The study is recruiting in Denmark.
