Prospective, randomized, double-blind, multicenter study to evaluate the safety and efficacy of an implantable tibial nerve stimulator in subjects with urgency urinary incontinence (UUI).
Sorry, accepting new patients by invitation only
The proposed study is designed to provide patients previously enrolled in Phase 1 and 2 studies of DCR-PHXC and their siblings (<18 years old) long-term access to DCR-PHXC, and to evaluate the long-term safety and efficacy of DCR-PHXC in patients with PH.
Safety and Feasibility Study of Autologous Engineered Urethral Constructs for the Treatment of Strictures
Sorry, not yet accepting patients
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.

Placement of a ureteral stent is a common urological intervention. For decades there was no valid measures available to assess quality of life issues in patients with ureteral stents, which has hampered the understanding of such symptoms and their true impact. In order to improve the outcomes associated with the placement of a stent, a validated tool is needed to measure its impact and the amount of undesirable effects it produces on patients requiring the placement of a stent. In 2003, the team of the Bristol Urological Institute developed a validated questionnaire called the: URETERAL STENT SYMPTOM QUESTIONNAIRE (USSQ). The questionnaire contains 38 items included in 6 sections. Despite the obvious need of a validated questionnaire, the latter remains unused by the community of peer urologists. Many of urologists consider it too long to be used in clinical practice and even for research purposes. This issue motivated the Canadian Endourology Group (CEG) to work collaboratively on the development of the CANADIAN ENDOUROLOGY GROUP STENT SYMPTOM SCORE (CEGSSS) in order to provide clinicians with a more useful and validated tool. To fulfill this objective, the CEG proceeds in three phases. Phase 1. A systematic, deliberative, and participatory approach mostly through face to face meetings, including patients, clinicians, and researchers in the field of Endourology to identify a minimum needs-based set of domains and items that are, clinically relevant to be included in the CEGSSS in order to ensure optimal uptake in the clinical setting. Phase 2. A pilot study to assess feasibility/acceptability and further refine the proposed set of items selected in phase 1 of the study. Phase 3. A multicentric prospective study to evaluate the validity, reliability and sensitivity to change of the CEGSSS. This research project is conducted by the Canadian Endourology Group (CEG), a panel of experts in the field of endourology in Canada. The CEG is a national member-based organization dedicated to enabling the profession to provide the highest possible standards of endourological care and to advance the science of endourology by collaboratively: 1. Fostering excellence in endourological practice through advocacy, education, research and practice support tools, 2. Leading evidence-based clinical practice through the development of practice standards and guidelines in endourology, 3. Providing continuous professional development for Canadian endourologists along the career-path continuum, 4. Providing leadership in public education for endourological conditions.
