Iatrogenic ureteral injury associated with lumbar spine surgery is an uncommon but devastating complication with associated medicolegal implications. ⋯ Ureteral injury associated with lumbar spine surgery is overreported in developed or developing countries. It should be considered in the differential diagnosis of any patient who presents with symptoms of acute abdomen after lumbar spine surgery, and patients who underwent restorative surgery had a good prognosis.

Multicenter Study
A multi-institutional analysis of factors influencing surgical outcomes for patients with newly diagnosed grade I gliomas.
To assess the impact of intraoperative magnetic resonance imaging (iMRI), extent of resection (EOR), and other factors on overall survival (OS) and progression-free survival (PFS) for patients with newly diagnosed grade I gliomas. ⋯ Patients with grade I gliomas have extended OS and PFS, which correlates positively with increasing EOR, especially for patients with pilocytic astrocytoma. iMRI may increase EOR, indicated by the rate of gross total resection after iMRI use but was not independently associated with increased OS or PFS.

Comparative Study Observational Study
Comparing standard performance and outcome measures in hospitalized pituitary tumor patients with secretory versus non-secretory tumors.
Patient safety indicators (PSIs) and hospital-acquired conditions (HACs) are reported quality measures. We compared their prevalence in patients with secretory and nonsecretory pituitary adenoma using the National (Nationwide) Inpatient Sample (NIS), Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. ⋯ Lack of significant difference in outcome measures after controlling for covariation is consistent with our finding that patients with nonsecretory tumor have more comorbidities on presentation for treatment. PSIs and HACs have limited ability to measure complications specific to pituitary tumors.

Multicenter Study Observational Study
Regional variation in the management of nontraumatic subdural hematomas across the United States.
Nontraumatic subdural hematomas are a common indication for inpatient hospitalization in the United States, yet there is little high-quality evidence regarding which patients should receive surgical or medical treatment. We sought to assess variation in surgical management and medical treatment with steroids for nontraumatic subdural hematomas across the United States. ⋯ There is considerable variability in surgical management of nontraumatic subdural hematomas across the United States based on age, sex, and region. Future studies should explore the reasons for the variability and attempt to better clarify indications for surgical management of subdural hematomas.

Comparative Study
Clinical features of neurogenic pulmonary edema in patients with subarachnoid hemorrhage.
Neurogenic pulmonary edema (NPE) is a clinical syndrome characterized by acute onset after central nervous system injury. Here, we investigated the clinical features of NPE in patients with subarachnoid hemorrhage (SAH). ⋯ Vertebral artery dissection and severe WFNS grade on admission were confirmed as significant risk factors for NPE. However, neurologic outcomes at discharge did not differ between groups, suggesting that poor outcomes due to NPE could be reduced by appropriate diagnosis and treatment.
