Nitrogen-doped layered porous carbon has been successfully fabricated from the biomass of porcine bladders via carbonization and KOH activation. The effects of KOH dosage on the structure, composition and capacitive property of carbon were investigated by a variety of means (SEM, HRTEM, XRD, Raman, XPS, BET and electrochemical test). Owing to the unique layered structure and rich heteroatom content of porcine bladders, the sample obtained at a KOH/carbon mass ratio of 2 were endowed with appropriate pore structure, large specific surface area (1881...

Female urethral diverticular cancer is a very rare entity with only around 100 cases reported so far in literature and accounts for <1% of all malignancies. In this article, we present a 47-year-old African American female with repeated hospital visits for urinary retention, hematuria, and urinary tract infections. Initial computed tomography imaging and cystoscopy was unremarkable except for a distended urinary bladder. Subsequent magnetic resonance imaging and corresponding cystoscopy eventually indicated the presence of a urethral diverticulum...

The use of shape memory polymers exhibiting water-induced shape recovery at body temperature and water solubility was proposed for the development of indwelling devices for intravesical drug delivery. These could be administered via catheter in a suitable temporary shape, retained in the bladder for a programmed period of time by recovery of the original shape and eliminated with urine following dissolution/erosion. Hot melt extrusion and fused deposition modeling 3D printing were employed as the manufacturing techniques, the latter resulting in 4D printing because of the shape modifications undergone by the printed item over time...

INTRODUCTION: Overactive bladder (OAB) medications often have poor tolerability or lack of efficacy with many progressing to 3 line therapy, such as sacral neuromodulation (SNM). Use of SNM may avoid the potential side effects of OAB medications, while achieving symptom improvement. We evaluated the post-operative rate of discontinuing OAB medications in patients who underwent SNM for refractory OAB. METHODS: A query of a prospectively-collected institutional review board- approved database for patients who underwent SNM was performed...

Macromolecules are potentially useful delivery systems for cancer drugs as their size allows them to utilize the enhanced permeability and retention effect (EPR), which facilitates selective delivery to (and retention within) tumors. In addition, macromolecular delivery systems can prolong circulation times as well as protecting and solubilizing toxic and hydrophobic drug moieties. Overall these properties and abilities can result in an enhanced therapeutic effect. Photodynamic therapy (PDT) combines the use of oxygen and a photosensitizer (PS), that become toxic upon light-irradiation...

BACKGROUND: Epidural catheters are state of the art for postoperative analgesic in abdominal surgery. Due to neurolysis it can lead to postoperative urinary tract retention (POUR), which leads to prolonged bladder catheterization, which has an increased risk for urinary tract infections (UTI). Our aim was to identify the current perioperative management of urinary catheters and, second, to identify the optimal time of suprapubic bladder catheter removal in regard to the removal of the epidural catheter...

Large uterine or cervical leiomyomas may cause acute urinary retention due to bladder outlet obstruction. We report two cases with acute urinary retention caused by cervical leiomyoma. Myomectomies were performed due to their desire of fertility and frozen-section examinations were reported as benign leiomyomas in both cases. The urinary symptoms completely resolved in two patients following myomectomies. In patients who are admitted with the complaint of acute urinary retention, cervical leiomyomas should be considered in differential diagnosis...

BACKGROUND: An intracranial dural arteriovenous fistula (DAVF) consists of a meshwork of arteriovenous shunts. Drainage of the fistula may be into a dural sinus or directly into cortical veins. Rarely, DAVFs drain exclusively into perimedullary veins. Prompt diagnosis is important as the clinical course is potentially life-threatening. CASE DESCRIPTION: A 67-year-old man presented with difficulties in walking and bladder retention. Magnetic resonance imaging (MRI) revealed central myelopathy, edema from C6 to T8, and dilated posterior medullary veins...
