39 Clinical Trials for Various Conditions
Renal autotransplantation (RAT) is a method of removing a kidney from its place of origin in a patient, repairing it, and transplanting it in another location of the body, generally the iliac fossa of the same patient.RAT is a relatively new technique; the first ever RAT procedure in the US was performed in 1963. Advances in preservation and transplantation techniques have made RAT a modality that can be utilized in complex renal diseases. RAT is indicated for conditions such as renal vascular disease, nutcracker syndrome, pelvic venous congestion, pelvic trauma, refractory stone disease and, in some cases, loin pain hematuria syndrome and conventionally unresectable renal tumors. Irrespective of the excellent outcomes shown by RAT, the conventional open approach requires a large midline xiphoid-to-pubis or flank incision for donor nephrectomy with a second pelvic incision for renal transplantation into the iliac fossa.The current gold standard approach to RAT is a laparoscopic nephrectomy followed by open auto-transplantation. However, this approach still requires a large pelvic incision. Robotic technology enables us to perform more complex minimally invasive surgery. Gordon et al. performed and reported the first completely intracorporeal robotic RAT to repair a ureteral injury in 2014.
Unrecognized abdominal and pelvic injuries can result in catastrophic disability and death. Sporadic reports of "occult" injuries have generated concern, and physicians, fearing that they may miss such an injury, have adopted the practice of obtaining computed tomography on virtually all patients with significant blunt trauma. This practice exposes large numbers patients to dangerous radiation at considerable expense, while detecting injuries in a small minority of cases. Existing data suggest that a limited number of criteria can reliably identify blunt injury victims who have "no risk" of abdominal or pelvic injuries, and hence no need for computed tomography (CT), without misidentifying any injured patient. It is estimated that nationwide implementation of such criteria could result in an annual reduction in radiographic charges of $75 million, and a significant decrease in radiation exposure and radiation induced malignancies. This study seeks to determine whether "low risk" criteria can reliably identify patients who have sustained significant abdominal or pelvic injuries and safely decrease CT imaging of blunt trauma patients. This goal will be accomplished in the following manner: All blunt trauma victims undergoing computed tomography of the abdomen/pelvis in the emergency department will undergo routine clinical evaluations prior to radiographic imaging. Based on these examinations, the presence or absence of specific clinical findings (i.e. abdominal/pelvic/flank pain, abdominal/pelvic/flank tenderness, bruising abrasions, distention, hip pain, hematuria, hypotension, tachycardia, low or falling hematocrit, intoxication, altered sensorium, distracting injury, positive FAST imaging, dangerous mechanism, abnormal x-ray imaging) will be recorded for each patient, as will the presence or absence of abdominal or pelvic injuries. The clinical findings will serve as potential imaging criteria. At the completion of the derivation portion of the study the criteria will be examined to find a subset that predicts injury with high sensitivity, while simultaneously excluding injury, and hence the need for imaging, in the remaining patients. These criteria will then be confirmed in a separate validation phase of the study. The criteria will be considered to be reliable if the lower statistical confidence limit for the measured sensitivity exceeds 98.0%. Potential reductions in CT imaging will be estimated by determining the proportion of "low-risk" patients that do not have significant abdominal or pelvic injuries.
The primary aim of this investigation is to prospectively and clinically validate a novel, reproducible method of quantitative application of compressive stress to a LC1 pelvic ring injury of indeterminate stability for the purpose of assessing quantitative pelvic ring displacement.
Pelvic ring fractures in the geriatric population are a rising problem for surgeons in industrialized countries. Many of these low-energy fractures are treated nonoperatively; however, pain is a significant factor in recovery of these patients and often inhibits their ability to mobilize. Most of these fractures are lateral compression type 1 injuries which are defined as an impaction to the sacrum with varying amounts of anterior/pubic root/rami fractures. Many of these patients in the geriatric population suffer from osteoporosis and the injuries are often sustained from a low-energy mechanism like a fall. The tenet of treatment for all osteoporotic fractures is early mobilization. It is well known that extended periods of bed rest will lead to pneumonia, decubitus ulceration, deep venous thrombosis, and, in the case of the pelvis, not prevent subsequent deformity. Calcitonin is a polypeptide containing 32 amino acids, and it plays a role in the regulation of bone metabolism as a hormone that prevents bone resorption. Intranasal salmon calcitonin (ISC) has been demonstrated to decrease pain and improve the level of activity in patients with acute vertebral osteoporotic compression fractures when administered within the first 5 days of onset of pain/injury. It has also demonstrated an immediate post analgesic effect in osteoporotic distal radius fractures treated nonoperatively. The antihyperalgesic action of calcitonin appears to be mediated by serotonin receptors. The purpose of this study is to evaluate the analgesic effect of ISC on geriatric patients with pelvic ring injuries who are treated nonoperatively.
The purpose of this study is to compare subcutaneous internal fixation and open plating of the symphysis in patients with a disruption of the symphysis requiring stabilization.
The purpose of this study is to determine whether displacement on one or all of the standard radiography views done within 6 months and 1 year after a pelvic injury is related to health related quality of life outcomes of patients with an isolated pelvic ring injury.
Obstetric anal sphincter injuries (OASIS) cause significant morbidity and are well known risk factors for sexual dysfunction, urinary and anal incontinence. Postpartum and breastfeeding are relative hypoestrogenic states with risk factors for dyspareunia and vaginal atrophy. Estrogen deficiency results in changes in the vaginal epithelium and poor tissue quality which results in poor wound healing. For postmenopausal women with vaginal atrophy undergoing surgery for pelvic organ prolapse, early administration of topical vaginal E2 therapy resulted in improved markers of tissue quality. Currently, there are limited studies to reference for proposed treatment modalities to improve sexual function and incontinence in this population. In this proposed randomized, placebo-controlled trial, women who sustain OASIS will be recruited and randomized to begin intravaginal estrogen therapy or placebo at their 2-week follow-up visit after hospital discharge. Participants will complete validated questionnaires relating to sexual function and pelvic floor disorders (urinary and anal incontinence) symptom distress and impact. The primary outcome of this study will be sexual dysfunction symptom severity measured by the female sexual function index (FSFI) at 6 months postpartum. Secondary outcomes will be urinary and anal incontinence distress and impact measured by St. Mark's score and the fecal incontinence quality of life (FIQOL) questionnaire for anal incontinence and urogenital distress inventory (UDI-6) for urinary incontinence. The objective of this study is to determine if intra-vaginal estrogen therapy improves sexual function and incontinence symptom distress and impact for postpartum women after OASIS.
The purpose of this study is to investigate of the differences in pelvic floor anatomy and function in women who have undergone a vacuum assisted vaginal delivery (VAVD) versus a forceps assisted vaginal delivery (FAVD) using three-dimensional ultrasound imaging. Women within 1-5 years after first delivery who did not have an internal delivery will be included. The total number of subjects is forty. This will include ten primiparous subjects who have undergone vacuum delivery, ten who have undergone forceps delivery, ten who had spontaneous vaginal delivery and ten who have undergone primary elective cesarean section.
The purpose of this study is to determine if patients with third and fourth degree obstetric lacerations benefit from a short course of pelvic floor physical therapy in the immediate postpartum period.
This study is designed to evaluate the safety and effectiveness of the Materna Prep Device in reducing pelvic muscle injuries during vaginal delivery. Subjects are randomized to Materna Prep Device or Standard of Care without use of the Materna Prep Device Intervention with the Materna Prep Device is expected to be a one-time use of approximately 30-90 minutes during the 1st stage of labor. Subject participation in the study is targeted to be 3 months from the time of the use of the device during delivery with optional long-term follow-up.
This study is designed to evaluate the safety and effectiveness of the Materna Prep Device in reducing pelvic muscle injuries during vaginal delivery. Subjects are randomized to Materna Prep Device or Standard of Care without use of the Materna Prep Device Intervention with the Materna Prep Device is expected to be a one-time use of approximately 30-90 minutes during the 1st stage of labor. Subject participation in the study is targeted to be 12 months from the time of the use of the device during delivery.
This study is investigating the use of tranexamic acid (TXA) in patients with pelvis and/or hip socket fractures that require surgery. TXA is FDA-approved in patients with hemophilia for short-term use to reduce hemorrhage and the need for replacement blood during tooth extraction. However, it has also been used extensively in severely injured patients after major trauma and during elective hip and knee replacements. Previous studies indicate TXA may reduce blood loss and the need for blood transfusions while being safe for use in most patients. TXA is fairly inexpensive and easy to obtain. The purpose of this study is to determine if TXA will make surgery in patients with pelvis and/or hip socket fractures safer and more cost efficient.
The purpose of this study is to determine the bone to skin depth for groups of lean, obese and morbidly obese patients. This information will be potentially helpful with implant design for obese and lean patients.
Pelvic fracture urethral injuries (PFUI) occur in up to 10% of pelvic fractures. It remains controversial whether initial urethral realignment after PFUI decreases rates of urethral obstruction and the need for subsequent urethral procedures. The retrospective record review should determine the utility of acute urethral realignment after PFUI.
The Materna device aims to prevent pelvic tissue damage by preventing overstretching of pelvic floor muscle fibers during delivery. The device is a single use, disposable, mechanical dilator that penetrates the first 4 cm or ½ of the vaginal canal and gradually expands the vagina from a resting diameter of 2-3 cm to the fully expanded size of a delivering fetus, roughly 8-10 cm. The Materna device will be used during the first stage of labor, for roughly 1-2 hours, in a hospital Labor and Delivery unit, under the supervision of trained clinical labor and delivery providers
The mechanical demands placed on the pelvic floor structures during vaginal delivery often exceed physiological tissue limits, resulting in maternal childbirth trauma, considerable postpartum morbidity, and increased risk of pelvic floor disorders(PFD). Injury to the perineum, vaginal supportive tissues, and pelvic floor muscles cause pain, infection, and dyspareunia, as well as pelvic organ prolapse(POP).Pregnancy and vaginal delivery are considered as a main risk factors in weakening the pelvic floor support and development of SUI, AI, and POP. CS is not only available countermeasure to reduce occurrence of obstetric trauma. Tactile imaging allows acquisition of 3D stress-strain data and 3D elasticity imaging or soft tissues.
This project will develop and preliminarily examine RESPECT, a trauma-sensitive psychological and physical therapy intervention to treat chronic pelvic pain, posttraumatic stress symptoms (PTS), and dysfunctional sexual behavior among women with sexual abuse histories. Patients will be recruited after being referred to pelvic floor physical therapy for treatment of chronic pelvic pain. Participants will complete seven sessions of individual cognitive behavioral psychotherapy. Physical therapy will be provided by clinicians who have been trained in trauma-sensitive treatment techniques. Treatment acceptability and outcomes will be assessed at baseline, mid intervention, post-intervention and follow-up via self-report measures. The RESPECT protocol is expected to be feasible to implement among sexual abuse survivors and to be well liked by patients. RESPECT is expected to reduce chronic pelvic pain, PTS, dysfunctional sexual behavior, treatment avoidance.
Abdominopelvic CT (CTap) utilization rose significantly in blunt trauma patients over the last decade. However, the observed increases failed to reduce mortality or missed injury rates. Several investigators have derived (citation) and validated (citation) clinical decision rules that attempt to identify a subset of low risk pediatric and adult patients in whom abdominopelvic CT imaging can be safely eliminated. Thus far these efforts failed to significantly reduce utilization. The investigators propose an alternative and complimentary strategy to decrease radiation by selectively eliminating the pelvic imaging portion of the abdominopelvic CT in low risk patients. In stable, alert patients without clinically evidence of pelvis or hip fractures, abdominal CT imaging alone (diaphragm to iliac crest) identifies clinically significant intra-abdominal injury (cs-IAI) as accurately as routine abdominopelvic imaging (diaphragm to greater trochanter) and results in a clinically important decrease in radiation exposure. The study will investigate this by comparing the accuracy of an imaging protocol using CT abdomen alone versus CT abdomen and pelvis to detect cs-IAI among stable, blunt trauma patients without suspected pelvis or hip fractures in two age groups: ages 3-17 years and 18-60. Patients will undergo CT imaging as deemed clinically indicated by the treating clinician. Among those who have abdominopelvic CT scans, the study will determine the test characteristics of CT abdomen alone versus CT abdomen plus CT pelvis imaging for the identification of cs-IAI. The reference standard will include initial radiology reports, with structured follow up of indeterminate scans, operative reports, and 7-day medical record review.
The aim of this project is to assess the effectiveness of the IlluminOss pelvic implants in patients with pelvic metastatic disease presenting with pain, risk of pathologic fracture, non-displaced or minimally displaced pathologic fracture of the pelvis, and geriatric patients with pelvic fragility fractures. Results from this study will be used to confirm preliminary clinically and possibly statistically significant reductions in pain and improvements in function among these patients.
The purpose of this study is to explore the impact of pelvic floor physical therapy during pregnancy on delivery and the impact on the woman's body and function. Currently there have not been any studies to our knowledge that have examined this relationship and the outcomes for the pregnant patient. The current research that is available is on pelvic floor training and perineal massage during pregnancy with positive outcomes. The questions we are looking to answer include: 1. Does pelvic floor physical therapy during pregnancy decrease the severity of perineal trauma during delivery? 2. Does pelvic floor physical therapy during pregnancy decrease the length of the second stage of labor (pushing)? 3. Does pelvic floor physical therapy during pregnancy decrease the occurrence of emergency C-section?
The purpose of this study is to evaluate the use of precision methods that quantify injury and response to injury to predict how short-term clinical outcomes are affected by initial and staged orthopaedic interventions in multiply injured patients (MIPs) who sustain major orthopaedic trauma.
Pressure ulcers (PU) are skin breakdowns that often form after blood flow in the skin is reduced from prolonged and repeated exposure to externally applied forces. As many as 85% of individuals with a spinal cord injury (SCI) report the occurrence of at least 1 PU since being injured. Despite the increasing attention and emphasis on prevention, PUs still represent a major health risk for persons with SCI. PUs and other skin breakdowns are at risk for becoming infected; it is not uncommon for many different types of "bugs" to be found in the wound. It has been assumed that the presence of these organisms did not impede wound healing or skin graft survival. The current proposal will use a new type of procedure that involves the direct injection of an antibiotic (in saline) into the skin beneath the wound; it is then distributed throughout the wound using a second device that uses sound waves. The study will determine if the antibiotic treatment and the standard of care improves the rate wound closure compared to the standard of care alone in persons with SCI and a chronic pelvic-region PU.
The submitted proposal is designed to reduce morbidity and mortality to injured children. Significant variability in the initial trauma assessment exists among institutions. The proposed project is a prospective, observational, multi-institutional study of children following blunt abdominal trauma. The specific goals of the project are to: 1) Document history, physical exam findings, imaging, and laboratory values, which are available to physicians during the initial trauma resuscitation prior to a decision on whether to order an abdominal computed tomography (CT) to evaluate for potential intra-abdominal injury; and 2) Derive and validate a multi-variable clinical prediction rule based on data variables readily available during the pediatric trauma resuscitation to identify patients at low risk for intra-abdominal injury, in which unnecessary CT might safely be avoided. Information from this study could be used to develop a more standardized approach to the evaluation for intra-abdominal injury following blunt trauma in children. This information could lead to significant improvement in the early recognition of injury and to improved resource utilization.
Tranexamic acid is an antifibrinolytic drug that has been used to decrease post-operative blood loss. This study is a prospective, randomized controlled trial investigating the use of tranexamic acid in fracture surgery around the hip and knee, in which significant blood loss (\>300mL) is expected. The hypothesis of this study is that tranexamic acid will be associated with a decrease in post-operative blood loss, as well as a decreased need for allogenic blood transfusion, in patients who have fracture surgery around the hip and knee.
It is the belief of the investigators that the current trends in complication rates associated with fixation of pelvic ring injuries and acetabular fractures in the obese are unacceptable. The overwhelming majority of these complications can be attributed to problems with surgical wound healing. The investigators feel that if a cost effective and easily performed intervention can be prospectively utilized in a specific at-risk orthopaedic trauma population in order to control a potentially devastating complication, then efforts in discovering such an intervention may prove valuable. It is our hypothesis that obese patients treated with V.A.C. therapy after standard closure of trauma-related, operative orthopaedic incisions will have fewer postoperative wound complications.
The purpose of this study is to see if fetal head circumference can be used as a predictor for who will experience a sphincter laceration while delivering.
We will rigorously test whether modulation of the motor cortex by transcranial direct current stimulation (tDCS) is an effective treatment for patients with chronic pelvic pain through the following specific aims: A) The primary aim of this study is to determine whether transcranial direct current stimulation applied to the motor cortex in patients with chronic pelvic pain induces a significant decrease in the pain or symptoms as compared with sham tDCS. We will also measure changes in the clinical symptom scores of multiple pelvic organs, drug intake (narcotic), anxiety, depression, traumatic stress, as well as overall improvement in the quality of life to assess the effects of this treatment. B) Determine the duration of the clinical effects of tDCS. We will therefore compare the amelioration of pain and related symptoms between active and sham tDCS for one year following treatment. C) Determine whether tDCS changes the threshold for pain detection as compared with sham tDCS. Patients with chronic pelvic pain have a lower threshold for pain as compared to healthy subjects and we hypothesized that this threshold will increase after stimulation with tDCS. D) Finally, we will examine whether 5 days of tDCS treatment is safe for use in chronic pelvic pain patients. Safety will be assessed through neuropsychological tests and adverse event reporting.
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)
For too many women, childbirth results in devastating consequences: involuntary loss of feces or urine (fecal or urinary incontinence). In fact, up to 50 percent of women with severe tears during childbirth may develop these problems. These new mothers avoid leaving home in order to stay close to a toilet, wear protective pads every day, and avoid activities they previously enjoyed such as exercise and sexual intercourse. It is not surprising that many of these women suffer from postpartum depression, and bonding with their newborns is compromised. Fecal and urinary incontinence occur due to injuries to the pelvic nerves and muscles during childbirth. Many researchers have focused on what can be done to prevent these injuries; however, few have investigated how to help the countless women who have already suffered from these injuries to the nerves and muscles. In other fields such as orthopedics and neurology, research shows that electrical stimulation can provoke nerve regeneration after injury. Applying this technology to women who have recently suffered from nerve injury during childbirth could have profound and life-changing effects. Investigators hypothesize that electrical stimulation immediately postpartum will markedly help pelvic nerves regenerate, minimizing rates of fecal and urinary incontinence for this vulnerable population of new mothers.
