Most lumbar intradural schwannomas present initially as radiculopathies with sensory disturbances. However, neurogenic bladder dysfunction may be one of the earliest manifestations and can cause long-term disability. We present the case of a patient with a L3-4 schwannoma (newly diagnosed owing to recurrent urinary retention and urinary tract infection) who finally underwent surgical resection. Improvement of bladder sensation was documented by urodynamic study and the patient was subsequently weaned off her Foley catheter with satisfactory outcome...

Introduction Transurethral resection of the prostate (TURP) is considered the gold standard surgical treatment for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia. The number of TURPs performed has declined significantly over the last three decades owing to pharmaceutical therapy. TURP data from a single institution for the years 1990, 2000 and 2010 were compared to assess the difference in performance. Methods A retrospective analysis was undertaken of all patients who underwent TURP between January and December 2010...

PURPOSE: PSMA-targeted PET in patients with prostate cancer (PCa) has a significant impact on treatment decisions. By far the most frequently used PSMA ligand is68 Ga-labelled PSMA-11. However, due to the availability of larger amounts of activity,18 F-labelled PSMA ligands are of major interest. The aim of the present study was to evaluate the biodistribution and performance of the novel18 F-labelled ligand PSMA-1007 at two different time points. METHODS: This retrospective analysis included 40 consecutive patients (mean age 68...

A spontaneous, non-traumatic, urinary bladder rupture is a rare condition. We describe a case of a 23-year-old male with a spontaneous bladder rupture secondary to urinary retention, due to an urethral stricture. He presented to the emergency department with voiding difficulties, severe abdominal pain and renal failure. Abdominal ultrasound revealed large amounts of ascites. After an unsuccessful attempt to place a Foley catheter a cystoscopy was performed which showed an urethral stricture. On CT-cystogram an intra-peritoneal bladder rupture was diagnosed and the patient underwent laparoscopic repair of the bladder wall...

Urothelial carcinoma of the bladder in childhood is extremely rare. We report on a 12-year-old girl with urothelial carcinoma of the bladder who presented with gross hematuria. Immunohistochemical staining showed normal levels of cytokeratin 20 expression and decreased levels of Ki67 and p53 expression. Human papillomavirus, which can be a cause of urothelial carcinoma of the bladder, was not detected by polymerase chain reaction. We reviewed the literature focusing on diagnostic tools for urothelial carcinoma of the bladder and determined that abdominal ultrasonography, with an extremely high sensitivity of 98%, could be a useful tool for postoperative follow-up in childhood...

In peripheral nerve (PN) injuries requiring surgical repair, as in PN transection, cellular and ECM remodeling at PN epineurial repair sites is hypothesized to reduce PN functional outcomes by slowing, misdirecting, or preventing axons from regrowing appropriately across the repair site. Herein this study reports on deriving and analyzing fetal porcine urinary bladder extracellular matrix (fUB-ECM) by vacuum assisted decellularization, fabricating fUBM-ECM nerve wraps, and testing fUB-ECM nerve wrap biocompatibility and bioactivity in a trigeminal, infraorbital nerve (ION) branch transection and direct end-to-end repair model in rat...

Interstitial cystitis (IC) is a chronic urinary tract disease that is characterized by unpleasant sensations, such as persistent pelvic pain, in the absence of infection or other identifiable causes. We previously performed comprehensive metabolomics profiling of urine samples from IC patients using nuclear magnetic resonance and gas-chromatography/mass spectrometry and found that urinary α-oxoglutarate (α-OG), was significantly elevated. α-OG, a tricarboxylic acid (TCA) cycle intermediate, reportedly functions to suppress the proliferation of immortalized normal human bladder epithelial cells...

Background -Venous thromboembolism can be a presenting symptom of cancer, but the association between lower limb arterial thrombosis and cancer is unknown. We therefore examined cancer risk and prognosis of cancer in patients with lower limb arterial thrombosis. Methods -Using nationwide population-based Danish medical registries, we identified all patients diagnosed with first-time lower limb arterial thrombosis (1994-2013) and followed them until the occurrence of any subsequent cancer diagnosis, emigration, death, or 30 November 2013, whichever came first...

Endometriosis and adenomyosis are histologically defined. The frequency of endometriosis cannot be precisely estimated in the general population. Endometriosis is considered a disease when it causes pain and/or infertility. Endometriosis is a heterogeneous disease with three well-recognized subtypes that are often associated with each other: superficial endometriosis (SUP), ovarian endometrioma (OMA), and deep infiltrating endometriosis (DIE). DIE is frequently multifocal and mainly affects the following structures: the uterosacral ligaments, the posterior vaginal cul-de-sac, the bladder, the ureters, and the digestive tract (rectum, recto-sigmoid junction, appendix)...

PURPOSE OF REVIEW: Recent advances in next-generation sequencing have allowed for detailed molecular analysis of urothelial carcinomas, with potentially significant clinical implications for personalized treatment. Our objective in this review is to highlight studies from the past year that have furthered the understanding of urothelial cancer genomics. RECENT FINDINGS: Recent studies by The Cancer Genome Atlas consortium further characterized urothelial carcinomas via molecular subtyping, and a schema was proposed to match each subtype with potential therapeutic implications...

Female pelvic organ prolapse (POP) is a common condition and the correction of prolapse remains a major challenge for the surgical community. A retrospective study of women with POP undergoing pelvic reconstructive surgery with the Elevate System followed-up for 48 months. A total of 138 women with POP were included in the study. We observed an objective cure rate of 94.9% for the anterior wall after 4 years' follow-up. The subjective cure rate was 97.1%. Improvement in the urinary symptoms was seen after the surgery: the number of asymptomatic patients increased from 14...

INTRODUCTION AND HYPOTHESIS: Mixed urinary incontinence (UI) is, on average, more severe than urgency UI or stress UI. We tested the hypothesis that mixed UI is a more advanced stage of UI by comparing transition probabilities among women with stress, urgency, and mixed UI. METHODS: We used data from the General Longitudinal Overactive Bladder Evaluation Study-UI, which included community-dwelling women, aged 40+ years, with UI at baseline. Study participants completed two or more consecutive bladder health surveys every 6 months for up to 4 years...

Neuroendocrine bladder cancer is a relatively rare but often lethal malignancy, with cell of origin, oncogenomic architecture and standard treatment poorly defined. Here we performed comprehensive whole-genome and transcriptome sequencing on a unique cohort of genitourinary neuroendocrine neoplasms, mainly small cell carcinomas of the urinary bladder. The mutational landscape and signatures of neuroendocrine bladder cancer strikingly resembled those in conventional urothelial carcinoma, along with typically mixed histologies, supporting a common cellular origin...

Early diagnosis of bladder cancer is crucial for improvement of cancer specific survival and recurrence rate. We analyzed the possible role of fluorescence urine analysis in bladder cancer diagnosis. The cohort consisted of 20 healthy controls, 40 patients with hematuria and 75 patients with hematuria and histologically proven bladder tumor. Synchronous fluores- cence spectra with a 70 nm wavelength difference were recorded for (1:1-1:128) urine dilutions. Concentration matrices of synchronous spectra (CMSS) were used to classify samples into tested groups...

INTRODUCTION: Laparoscopic lateral pelvic lymph node dissection (LPLD) is technically challenging because of the complicated anatomy of the pelvic wall. To overcome this difficulty, we introduced preoperative 3-D simulation. The aim of the study is to investigate the usefulness of preoperative 3-D simulation for the safe conduct of laparoscopic LPLD for rectal cancer. METHODS: After undergoing colonoscopy, patients were brought to the radiology suite where multi-detector row CT was performed...

AIMS: To evaluate whether baseline symptoms and outcomes are influenced by gender in a matched cohort undergoing neuromodulation. METHODS: Patients in our prospective neuromodulation database that had a tined lead placed were reviewed. Those that had implantable pulse generator (IPG) placed were matched on age and urologic diagnosis. History, voiding diaries, satisfaction, Interstitial Cystitis Symptom/Problem Index (ICSIPI), and overactive bladder symptom severity (OABq ss)/health-related quality of life (HRQOL) preimplant and over 3 years were evaluated using descriptive statistics, repeated measures, and matched pair GEE or mixed analyses...

BACKGROUND: Distinguishing between urinary tract infection (UTI) and colonization (UTC) in patients with neurogenic bladders who require clean intermittent catheterization (CIC) is difficult. Urinary neutrophil gelatinase-associated lipocalin concentrations (uNGAL) are increased in UTIs. Our objective was to determine the predictive accuracy of uNGAL for UTI in CIC-dependent children. METHODS: Cross-sectional study of CIC-dependent patients from August, 2015 to November, 2016...

Currently, we have assessed the neuronal control of the urinary bladder in radiation cystitis and whether interstitial cells contribute to the condition. Fourteen days following bladder irradiation (20 Gy) rats were sedated and the urinary bladder was cut in two sagittal halves where electrical field stimulation (EFS; 5-20 Hz) was applied on the pelvic nerve afferents or stretch (80 mN) on one half of the urinary bladder, while contractions were registered on the contralateral half of the urinary bladder in the absence and presence of increasing doses of imatinib (1-10 mg/kg; inhibitor of c-kit+ interstitial cells), atropine (1 mg/kg; to block muscarinic M3 receptors) or PPADS (2 mg/kg; to block P2X1 purinoceptors)...

Spinal cord epidural stimulation (SCS) represents a form of neuromodulation for the management of spasticity and pain. This technology has recently emerged as a new approach for potentially augmenting locomotion and voiding function in humans and rodents after spinal cord injury. However, the effect of SCS on micturition has not been studied extensively. Here, SCS was first applied as a direct stimulus onto individual segmental levels of the lumbar spinal cord in rats to map evoked external urethral sphincter (EUS) electromyography activity and SCS-induced voiding contractions...

BACKGROUND: In veterinary medicine, contrast-enhanced ultrasonography allowed the accurate quantification of liver, splenic and kidney vascularization in healthy dogs and the differentiation between malignant and benign hepatic, renal, and splenic nodules in dogs and cats based on perfusion patterns. The utility of contrast-enhanced ultrasonography in other applications is still under study. The aim of this study was to develop diagnostic criteria by contrast-enhanced ultrasonography in 8 client-owned adult dogs affected by urinary bladder transitional cell carcinoma with definitive diagnosis made by cytopathologic evaluation after suction biopsy...
