Boys with posterior urethral valves have bladder dysfunction of varying severity. Early treatment of these children with anticholinergics is recommended by some teams, although there have never been any clear studies on the subject. To our knowledge, no comparative study of the evolution of valve bladders with or without treatment has been carried out to date. Anticholinergic treatment, although it may be beneficial in patients with abnormal bladder function, such as the neurologic bladders ( in Spina Bifida) for example, may have side effects and may not be of benefit for this valve population. The evolution of the valves could be spontaneously favorable. This study would be the first randomized clinical trial of early therapeutic drug intervention in the posterior urethral valve population.

This is a Phase I clinical study to determine the safety and efficacy of using autologous, engineered urethral constructs for the treatment of urethral strictures in adult males. The proposed study design is a prospective non-randomized and uncontrolled single-center investigation. Autologous urothelial cells (UCs) and smooth muscle cells (SMCs), obtained from enrolled male subjects' bladder tissue samples, will be culture expanded in vitro and used to seed tubular PGA scaffolds to create autologous urethral constructs for the repair of urethral strictures.

The primary objective of this clinical trial is to evaluate the safety of autologous engineered corpora cavernosa + albuginea constructs for treatment of complex penile deformities. Autologous endothelial and smooth muscle cells obtained from enrolled subjects' corpora cavernosa biopsy sample, will be culture expanded in vitro and used to seed decellularized corpora cavernosa + albuginea obtained from cadaveric-donors to create autologous bioengineered corpora cavernosa/albuginea constructs for repair of damaged penile tissues.

This is a single-armed, single-centre, non-blinded phase II trial to assess efficacy of induction chemo-immunotherapy for resectable node-positive squamous cell carcinoma of the penis

This is a multicenter real world study (RWS) initiated by the investigator. Eligible patients will be selected for treatment with second-line treatment including vorolanib and followed up. The real survival data of patients after medication will be collected and compared with the data of CONCEPT study, and multi-factor stratified analysis of the efficacy of voronib will be conducted.

This is a non-blinded phase 2 trial in Stage II-IIIa urothelial cancer randomizing pre-operative nivolumab with or without relatlimab to assess whether bladder preservation after dual immunotherapy would be a viable treatment option for patients responding to treatment

Radium-223 is an established radionuclide therapy for patients with metastatic castration resistant prostate cancer (mCRPC) and symptomatic bone metastasis. Patients are eligible for this treatment when they have mCRPC and bone metastases; limited extraskeletal lesions (local prostate, lymph nodes \<3 cm) on conventional contrast enhanced CT (ceCT) were allowed in the registration trial(1). Previous research revealed that extraskeletal disease on ceCT and bone scans correlates with a poor response. Meanwhile, 68Ga-PSMA-PET/CT emerged as more sensitive imaging strategy that increases the detection of extraskeletal prostate cancer metastases. It is unclear whether these extraskeletal lesions harbour any predictive value in the treatment of mCRPC patients with Radium-223.

This a single-center, prospective, exploratory study. Patients with metastatic castration-resistant prostate cancer (mCRPC) scheduled to undergo Lutetium labelled prostate-specific membrane antigen radioligand therapy (LuPSMA RLT) at the West Los Angeles VA (WLA-VA) will be imaged with a baseline F-18 fluorodeoxyglucose positron emission tomography/computed tomography 18F-FDG PET/CT and a 18F-DCFPyL PET/CT (18F-DCFPyL (2-(3-{1-carboxy-5-\[(6-18F-fluoro-pyridine-3-carbonyl)-amino\]-pentyl}-ureido)-pentanedioic acid)positron emission tomography/computed tomography , as per standard of care in our institution. All patients further undergo eventual follow-up prostate-specific membrane antigen positron emission tomography (PSMA PET) after the 2nd, 4th, and 6th LuPSMA RLT cycle. In this prospective study, an18F-Fluciclovine positron emission tomography/computed tomography ( Axumin PET/CT )will be additionally obtained at baseline (pre-LuPSMA RLT), and after the 2nd, 4th, 6th LuPSMA RLT cycles. Axumin PET/CT will be acquired within 7 days from the PSMA PET. This study is open to Veterans only.
