Active clinical trials for "Urologic Diseases"

This is a single-center, prospective, single-arm clinical study to evaluate the feasibility, safety, and performance of VenoStent's SelfWrap® Bioabsorbable Perivascular Wrap on arteriovenous fistulas (AVFs). All participants are chronic kidney disease (CKD) patients already receiving hemodialysis treatments that are referred for creation of a new arteriovenous fistula (AVF).

This study is designed to assess if there is a significant difference in same day discharge rates after Holmium Laser Enucleation of the Prostate (HoLEP). The investigators attempt to perform HoLEP as a same-day discharge (SDD) procedure, but at Northwestern Memorial, the SDD rate is currently approximately 60%. The limiting factor in SDD is hematuria. Tranexamic acid (TXA) is a clot promoting drug that is commonly used by orthopedic, cardiac and obstetric surgeons to prevent bleeding. The primary outcome will be to assess if there is a difference in SDD rates in those who receive TXA vs. those who do not. Secondary outcomes will assess bleeding complications (defined as unplanned ED visit/clinic visit/procedure/admission related to bleeding, clot retention, clot evacuation, need for perioperative transfusion) between participants who receive TXA vs. those do not. The study will also assess differences in perioperative complications associated with TXA including but not limited to: deep venous thrombosis, pulmonary embolism, cerebrovascular events, between the groups. The study will also assess for the duration of postoperative hematuria between groups as well as differences in operative times between the groups. The investigators anticipate that there may be up to a 25% increase in SDD rates in those who receive TXA vs. those who do not.

To explore the optimal urethral coverage in hypospadias repair by comparing the success rate of both covering techniques: Dartos fascia versus Tunica Vaginalis flap.

Supplements and functional foods are now readily available and usable by the general population. Many supplemnets are commonly used in poly-treated patients where interactions or adverse events may develop, therefore we evaluate in the rela life the use of nutraceuticals, their clinical effects and the development of adverse drug reactions

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.

To determine the safety and efficacy of Amniotic and Umbilical Cord Tissue for the treatment of the following condition categories: Orthopedic, Neurologic, Urologic, Autoimmune, Renal, Cardiac and Pulmonary Conditions. The hypotheses are that the treatments are not only extremely safe, but also statistically beneficial for all conditions. Outcomes will be determined by numerous valid outcome instruments that compile general quality of life information along with condition-specific information as well.

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.

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: Fostering excellence in endourological practice through advocacy, education, research and practice support tools, Leading evidence-based clinical practice through the development of practice standards and guidelines in endourology, Providing continuous professional development for Canadian endourologists along the career-path continuum, Providing leadership in public education for endourological conditions.
