Female urethral stricture disease is very rare, but can cause bothersome urinary tract symptoms. Because of rarity, knowledge of how to treat true female urethral strictures can be lacking. Strictures can be caused by infection, trauma, instrumentation, or prior urethral surgery. Treatment options vary depending on patient goals and overall health, as well as the location, length, and severity of the stricture. These include serial dilation, internal urethrotomy, or urethroplasty. Local vaginal flaps and buccal free grafts can be used for onlay urethroplasty with good success rates, although many other techniques are described. Pelvic fracture urethral distraction defects (PFUDs) in women are especially rare. Acutely, they may require urgent repair with primary anastomosis (in contradistinction to male PFUDs which are not reanastomosed acutely), and chronic cases may require urethroplasty. © 2013 Springer Science+Business Media New York.

Impairment of hippocampus-dependent cognitive processes has been proposed to underlie age-related deficits in navigation. Animal studies suggest a differential role of hippocampal subfields in various aspects of navigation, but that hypothesis has not been tested in humans. In this study, we examined the association between volume of hippocampal subfields and age differences in virtual spatial navigation. In a sample of 65 healthy adults (age 19-75 years), advanced age was associated with a slower rate of improvement operationalized as shortening of the search path over 25 learning trials on a virtual Morris water maze task. The deficits were partially explained by greater complexity of older adults' search paths. Larger subiculum and entorhinal cortex volumes were associated with a faster decrease in search path complexity, which in turn explained faster shortening of search distance. Larger Cornu Ammonis (CA)1-2 volume was associated with faster distance shortening, but not in path complexity reduction. Age differences in regional volumes collectively accounted for 23% of the age-related variance in navigation learning. Independent of subfield volumes, advanced age was associated with poorer performance across all trials, even after reaching the asymptote. Thus, subiculum and CA1-2 volumes were associated with speed of acquisition, but not magnitude of gains in virtual maze navigation. © 2015 The Author. Published by Oxford University Press.

Purpose To assess whether diverse tumor location(s) show differences in percutaneous cryoablation (PCA) outcomes of cancer control, morbidity, and ablation volume reduction for many soft-tissue tumor types. Materials and Methods A total of 220 computed tomography (CT)- and/or ultrasonography-guided percutaneous cryotherapy procedures were performed for 251 oligometastatic tumors from multiple primary cancers in 126 patients. Tumor location was grouped according to regional sites: retroperitoneal, superficial, intraperitoneal, bone, and head and neck. PCA complications were graded according to Common Terminology Criteria for Adverse Events (version 4.0). Local tumor recurrence and involution were calculated from ablation zone measurements, grouped into 1-, 3-, 6-, 12-, 18-, and 24-month (or later) statistical bins. Results Tumor and procedure numbers for each site were 75 and 69 retroperitoneal, 76 and 62 superficial, 39 and 32 intraperitoneal, 34 and 34 bone, and 27 and 26 head and neck. Average diameters of tumor and visible ice during ablation were 3.4 and 5.5 cm, respectively. Major complications (ie, grade >3) attributable to PCA occurred after five procedures (2.3%). At 11 months average follow-up (range, 0-82 mo), a 10% total recurrence rate (26 of 251) was noted; three occurred within the ablation zone, for a local progression rate of 1.2%. Average time to recurrence was 4.9 months, and, at 21 months, the initial ablation zone had reduced in volume by 93%. Conclusions CT-guided PCA is a broadly safe, effective local cancer control option for oligometastatic disease with soft-tissue tumors in most anatomic sites. Other than bowel and nerve proximity, PCA also shows good healing if proper visualization and precautions are followed. © 2013 SIR.

Vaginal microbiome studies provide information that may change the way we define vaginal flora. Normal flora appears dominated by one or two species of Lactobacillus. Significant numbers of healthy women lack appreciable numbers of vaginal lactobacilli. Bacterial vaginosis (BV) is not a single entity, but instead consists of different bacterial communities or profiles of greater microbial diversity than is evident from cultivation-dependent studies. BV should be considered a syndrome of variable composition that results in different symptoms, phenotypical outcomes, and responses to different antibiotic regimens. This information may help to elucidate the link between BV and infection-related adverse outcomes of pregnancy.

Trauma is the leading cause of death between the ages of 1 and 44 years in the USA. While stabilization of life-threatening injuries is the primary goal in the evaluation of all trauma patients, subsequent diagnosis and treatment of secondary injuries are requirements for good trauma care. The genitourinary system is involved in 10% of trauma cases, and these injuries can be associated with considerable morbidity and mortality. Accordingly, physicians involved in the initial evaluation and subsequent management of trauma patients should be aware of the diagnosis and treatment of injuries that can occur in the genitourinary system. In 2009, the European Association of Urology provided specific recommendations for the evaluation, diagnosis and management of genitourinary trauma. Here, we review and discuss these recommendations in order to provide a concise summary for clinicians involved in the evaluation and management of trauma patients and their associated genitourinary injuries. © 2010 Macmillan Publishers Limited.

Contaminated sediments are a pervasive problem in the United States. Significant economic, ecological, and social issues are intertwined in addressing the nation's contaminated sediment problem. Managing contaminated sediments has become increasingly resource intensive, with some investigations costing tens of millions of dollarsand the majority of remediation projects proceeding at a slow pace. At present, the approaches typically used toinvestigate, evaluate, and remediate contaminated sediment sites in the United States have largely fallen short of producing timely, risk-based, cost-effective, longterm solutions. With the purpose of identifying opportunities for accelerating progress at contaminated sediment sites, the US Army Corps of Engineers-Engineer Research and Development Center and the Sediment ManagementWork Group convened a workshop with experienced experts from government, industry, consulting, and academia. Workshop participants identified 5 actions that, if implemented, would accelerate the progress and increase the effectiveness of risk management at contaminated sediment sites. These actions included: 1) development of a detailed and explicit project vision and accompanying objectives, achievable short-term and long-term goals, and metrics of remedy success at the outset of a project, with refinement occurring as needed throughout the duration of the project; 2) strategic engagement of stakeholders in a more direct and meaningful process; 3) optimization of risk reduction, risk management processes, and remedy selection addressing 2 important elements: a) the deliberate use of early action remedies, where appropriate, to accelerate risk reduction; and b) the systematic and sequential development of a suite of actions applicable to the ultimate remedy, starting with monitored natural recovery and adding engineering actions as needed to satisfy the project's objectives; 4) an incentive process that encourages and rewards risk reduction; and 5) pursuit of sediment remediation projects as a public-private collaborative enterprise. These 5 actions provide a clear path for connecting current US regulatory guidance to improved practices that produce better applications of science and risk management and more effective and efficient solutions at contaminated sediment sites.

Although straightforward male urethral stricture disease is commonly encountered in the scope of general urologic practice, complex urethral strictures are less common and require a more systematic approach. Complex urethral stricture surgery for long and panurethral strictures, after failed hypospadias repair, and for recurrent posterior urethral distraction defects requires a dynamic treatment paradigm. A multistaged urethral reconstruction is often necessary owing to hostile urethral tissue, especially after multiple previous procedures. A perineal urethrostomy sometimes offers improved quality of life for patients with complex urethral stricture disease, particularly if they have undergone previous failed repairs. Recurrent posterior urethral distraction defects are best treated with excision of the scarred urethral segment and re-anastomosis. Urethral stricture disease after treatment for prostate cancer requires multiple treatment approaches given the often poor tissue quality and likelihood of stricture recurrence. © 2010 Macmillan Publishers Limited.

Background: Fundamentals of Laparoscopic Surgery (FLS) certification is reliable and valid; the American Board of Surgery requires FLS certification. Dynamics of skill retention after FLS training effect training schedules for residents. We hypothesized that the initial elevation of performance levels after FLS training would deteriorate predictably with time. Methods: FLS performance data on 16 new surgical residents (R01s) was examined retrospectively. These R01s trained at 16 weekly sessions. Training included 4 FLS tasks, VR simulator tasks, and open surgical skills. FLS skills were practiced weekly with feedback but no instruction. Performance was tested PRE, POST, and DELAY. Outcome metrics were task completion times (TCTs). Results: POST TCTs were below PRE TCTs in all R01s for all FLS tasks (P < 0.05). No difference was seen between the DELAY TCT and POST TCT for peg transfer (P = 0.726) and pattern cut (P = 0.114). The DELAY TCTs were longer than POST TCTs for extra- and intra corporeal knot-tying (P < 0.0001 and P = 0.029). Relative retention was 103% for peg transfer, 85% for pattern cut, 47% for extracorporeal knot tying, and 59% for intracorporeal knot tying. However, many individual's displayed DELAY TCT equal to or lower than POST TCT implying full retention. Conclusions: This study extends the data on FLS skill retention to an actual "production" training curriculum. This FLS training provided effective learning in R01s. Although performance levels fell across these tasks on average and for the majority of individual R01s, significant skill retention remained at 7-8 months. Early training will enable R01s to maintain or elevate skill levels with additional training sessions. © 2010 Elsevier Inc. All rights reserved.

The 2015 William H. Harridge lecture of the 2015 Midwest Surgical Association concentrated on the evolution and performance characteristics of nonoperative management of even severe renal injury. One of the first mentions of nonoperative renal trauma occurs after World War II. Since that time through the early 2000s, only 1 or fewer papers per year appeared in the literature. The mid-2000s had an explosion of interest and publications on the subject, resulting in our modern understanding of the principles. The principles of nonoperative management are as follows: (1) operate immediately if the patient is bleeding to death; (2) observe initially, but step in with metered responses as necessary; (3) use ureteral stents for symptomatic or growing urinoma; (4) use angioembolization for nonemergent bleeding or for urgent bleeding if your center can manage this; and (5) do open surgery when needed (not "never"). © 2016 Elsevier Inc.

Approximately 4-14% pelvic fractures cause a posterior urethral injury. Pelvic fractures associated with straddle injuries or large trauma accidents are more frequently involved with this kind of lesions. Primary open repair of the urethral injury is discouraged in the acute setting. 3-6 months after urinary diversion a formal open reconstruction can be safely attempted. This gives time for scar maturation, reabsorption of pelvic hematomas, and relative restoration of anatomical fascial layers. The complexity of such interventions can be minimized following proper diagnostic and surgical protocols. Anastomotic urethroplasty under the precepts of the progressive perineal approach provides an excellent treatment option for these patients. The aim of this paper is the detailed description of the procedure for the treatment of such injuries.
