Urodynamic studies have been carried out in 10 boys with the prune belly syndrome. In spite of gross radiological changes condition is compatible normal voiding dynamics. Filling cystometrograms show a marked shift to right. Pressure/flow may demonstrate an unbalanced mechanism which can be treated by urethrotomy. Following urethrotomy urethral pressure profiles showed significant fall, flow rates increased and residual urine volumes were reduced. Urological treatment syndrome should...
Some patients are diagnosed with asymptomatic meningioma(s) after undergoing a screening CT and MRI for minor ailments or postresection.To help clinicians in decision making treatment of meningiomas.A single center retrospective cohort study 117 122 tumors treated Gamma Knife radiosurgery (GKRS; Elekta AB, Stockholm, Sweden). Patients were followed longitudinal imaging clinical evaluations. Tumor volumetry developments new signs symptoms GKRS the end points study.Median patient age at was 60...
OBJECTIVE Early surgical intervention for patients with pituitary apoplexy (PA) is thought to improve visual outcomes and decrease mortality. However, some may have good clinical without surgery. The authors sought compare the radiological of PA who were managed conservatively versus those underwent early METHODS Patients symptomatic identified. Radiological, endocrinological, ophthalmological data reviewed. progressive deterioration or ophthalmoplegia candidates surgery (within 7 days)....
BACKGROUND Venous sinus injury resulting in thrombosis is a possible complication of skull base surgery and neck dissection. Although usually asymptomatic, can obstruct the dominant cranial venous outflow pathways, leading to cycle increased intracranial pressure secondary congestion, which further compresses remaining sinuses positive feedback loop. This present with symptoms resembling idiopathic hypertension. OBSERVATIONS A patient underwent left mastoidectomy for chronic mastoiditis,...
INTRODUCTION: Arteriovenous malformations (AVMs) may cause intracranial hemorrhaging and are usually identifiable by either non-invasive vascular imaging, such as computed tomography angiography (CTA) or magnetic resonance (MRA), with 2- 3-dimensional angiography. However, some rare micro-AVMs (<1cm) not visible on standard METHODS: We identified all patients undergoing diagnostic for suspected brain AVM. Imaging was reviewed cases were in which a micro-AVM diagnosed exclusively CBCT...
Hematoma expansion is a consistent predictor of poor neurological outcome and mortality after spontaneous intracerebral hemorrhage (ICH). An incomplete understanding its biophysiology has limited early preventative intervention. Transport-based morphometry (TBM) mathematical modeling technique that uses physically meaningful metric to quantify visualize discriminating image features are not readily perceptible the human eye. We hypothesized TBM could discover relationships between hematoma...

BACKGROUND AND IMPORTANCE: Intracranial intraluminal mass lesions are rare and challenging to biopsy using noninvasive methods. Obtaining tissue for diagnosis is critical guiding treatment, yet traditional approaches such as craniotomy pose significant risks. In this case report, we describe the first use of an aspiration catheter stent retrieval system safely successfully perform endovascular in a patient with exclusively meningioma. CLINICAL PRESENTATION: The had history medulloblastoma,...

The role of adenosine 3',5'-cyclic monophosphate (cAMP)-dependent protein kinase A (PKA) in mediating the hydrosmotic effect vasopressin vitro microperfused rabbit cortical collecting ducts (CCDs) was examined. We measured PKA substrate phosphorylation and water permeability [hydraulic conductivity (Lp) = 10(-7) cm.atm-1.s-1], stimulated by substituted cAMP analogues selective for a unique binding site (site or B) on regulatory subunit (R). Synergy between A- B-selective suggests involvement...
OBJECTIVE Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a common problem during the postoperative course after pituitary surgery. Although treatment this condition well characterized, prevention strategies are less studied and reported. The authors sought to characterize outcomes predictive factors SIADH implementation routine fluid restriction for patients undergoing endoscopic transsphenoidal surgery adenoma. METHODS In March 2018, 1000 ml/day 7 days was instituted...
Abstract BACKGROUND Proximal junctional kyphosis (PJK) is a common postoperative complication after adult spinal deformity (ASD) surgery and may manifest with neurological decline, worsening deformity, instability, which warrant reoperation. Rates of PJK be as high 69.4% ASD surgery. OBJECTIVE To evaluate the efficacy tethers for prophylaxis multilevel instrumented minimum 2-yr follow-up. METHODS Single-center retrospective analysis patients (age ≥18 yr) who underwent index operations...
Hematoma and perihematomal edema volumes are important radiographic markers in spontaneous intracerebral hemorrhage. Accurate, reliable, efficient quantification of these will be paramount to their utility as measures treatment effect future clinical studies. Both manual semi-automated methods hematoma volumetry time-consuming susceptible inter-rater variability. Efforts now underway develop a fully automated algorithm that can replace them. A (QUANTUM) study establish inter-quantification...
OBJECTIVE The COVID-19 pandemic caused a significant disruption to residency recruitment, including sudden, comprehensive transition virtual interviews. authors sought characterize applicant experiences and perceptions concerning the change in application, interview, match process for neurological surgery during 2020–2021 recruitment cycle. METHODS A national survey of neurosurgical applicants from application cycle was performed. This developed cooperation with Society Neurological Surgeons...
