12 Clinical Trials for Various Conditions
The objective of this prospective study is to examine the correlation and effects of bowel dysfunction on outcomes for patients undergoing holmium laser enucleation of prostate (HoLEP) for lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH).The investigator hypothesizes that patients who have more bowel dysfunction based on higher severity scores on patient-reported validated questionnaires will experience more symptoms in the immediate post-operative period and may have slower recovery of urinary control. Assessment of pre, peri, and post-procedural bowel dysfunction via the Constipation Severity Score (CSS) and Vaizey Incontinence Questionnaire will aid the analysis.
Demonstrate and compare the 3D morphology of the bladder wall in full and drained states with 2 different kinds of bladder catheters in place. (Foley Catheter vs. Cystosure Catheter)
This study will evaluate the safety and performance of the Medtronic Hugo™ RAS System when used for urologic RAS procedures.
Numerous studies demonstrate that patients have improved immediate recovery characteristics following desflurane anesthesia compared to other volatile agents, including sevoflurane. There is limited evidence in the literature to suggest that patients undergoing sevoflurane, compared to desflurane anesthesia, may suffer from limitation in function and cognitive ability for an undetermined, but prolonged period of time following surgery. These differences are not explained pharmacokinetically and may be a result of a direct neurotoxic effect of sevoflurane. An unresolved question is the time required for the ability to return to complex tasks, such as driving, following anesthesia. Commonly, patients are advised not to drive or make important decisions for 24 hours following anesthesia, but this is not well-studied and proscribed on an empiric, rather than scientific, basis with very limited data available.This study will better define recovery characteristics and characterize the severity and duration of cognitive impairment following sevoflurane or desflurane anesthesia after brief outpatient urologic surgery in elderly females using tests of cognitive ability coupled with performance on a driving simulator and cognitive task tests to objectively measure not only testing performance, but also cognitive effort in performing these tests.
The purpose of this investigation is to evaluate methods in spinal cord injured individuals to improve reflex urination. Anal dilation will be investigated to reduce high urethral resistance and a vibrator on the patient's bottom will be tested to induce more sustained bladder contractions for better bladder emptying.
The investigators will continue their work with implanted stimulators to improve bladder and bowel function. Electrical stimulation produces simultaneous contraction of sphincters with the target organs, making emptying difficult. By optimizing electrode placement, employing a new electrode design and waveform choice, it is hoped to improve the 50% of subjects able to defecate with existing approaches. This is part of a multi-center study with multiple support sources, including Rehab R\&D, PVA and a commercial stimulator company.
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 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 Connected Catheter is a fully internal, urethral indwelling urinary prosthesis designed for improved bladder management in males with urinary retention disorders requiring catheterization. It is a sterile, extended-use device that resides fully internally to the male lower urinary tract for an intended use life of up to 7 days per catheter.

This is a Phase 2b, prospective, open-label study designed to evaluate the safety, tolerability, PK, and PD of FAST PV and mGFR Technology in healthy subjects and patients with varying degrees of renal impairment.
Injuries to the genitalia are of concern to the military with emphasis placed on the surgical reconstruction and psychological health of these Wounded Warriors. However, despite significant surgical advances in microvascular surgery and autologous free tissue transfer, conventional reconstructions cannot truly replace the complicated structures and functions of the penis including the urethra, erogenous sensation, and erectile corporal bodies. Conventional reconstruction poses several challenges: patients may not have sufficient donor tissue due to other injuries or previous surgery; multiple operations are often needed to restore the neophallus; the final reconstruction only approximates the penis' native form; recreating the urethra is challenging and the new urethra is prone to stricture and fistula formation; the erectile function necessary for sexual intercourse is often lacking; and insufficient protective sensation can lead to penile implant extrusion, infection, subsequent explantation or loss of the reconstruction. The investigators propose this clinical trial to determine functional outcomes and quality of life for Wounded Warriors and civilians who choose to undergo penile allotransplantation. The investigators will combine extensive experience performing total penile reconstruction in a large population affected by congenital, traumatic, and therapeutically extirpated Genitourinary deformities and expertise in reconstructive transplantation using an immunomodulatory protocol to for this study. The investigators anticipate penile transplantation can potentially replace "like with like," restoring the appearance, anatomy, and function of the recipient in a manner far superior to autologous reconstruction. This project will establish the ability to perform penile allotransplantation using an immunomodulatory protocol and will compare outcomes with conventional phalloplasty patient results. Study Design: This is a non-randomized subject self-controlled clinical trial to implement a cell-based immunomodulatory protocol for penile allotransplantation. An intermediate deliverable is achieving allograft survival and functional return with reduced dosing/frequency of maintenance immunosuppression on steroid-free monotherapy (tacrolimus) immunosuppression. The long-term deliverable and goal is to demonstrate superior outcomes when compared to satisfaction and QOL in conventional phalloplasty patients 12-60 months post-transplant.
