We describe a 75-year-old man with undifferentiated prostate cancer that was treated with radiation therapy. He presented at a nearby general hospital with dysuria and pain upon micturition. He was diagnosed with undifferentiated prostate cancer by a needle biopsy and referred to our hospital for further examination and treatment. Enhanced computed tomography and magnetic resonance images showed prostate cancer and right obturator lymph node metastasis measuring 2.5 cm. Cystoscopy and colonoscopy revealed direct invasion of the urinary bladder and rectum...

PURPOSE: Overactive bladder (OAB) causes urinary urgency, usually accompanied by frequency and nocturia. Alpha 1-adrenergic receptor (α1-AR) antagonists are known to improve lower urinary tract symptoms associated with OAB. The α1-AR antagonists constitute a variety of drugs according to the receptor subtype affinity. This study investigated the efficacy of tamsulosin, naftopidil, and a combination of the two on OAB rats. METHODS: The OAB rat model was induced by an intraperitoneal injection of cyclophosphamide for 14 days...

INTRODUCTION: Overactive Bladder (OAB) accounts for 40-70% cases of incontinence. The etiology is unknown though detrusor instability is found in urodynamic evaluation of almost all cases. Detrusor instability or hyperreflexia can be inhibited by direct inhibition of impulses in the pre-ganglionic afferent neuron or by inhibition of bladder pre-ganglionic neurons of the efferent limb of micturition reflex. Transcutaneous Electrical Nerve Stimulation (TENS) is based on the gate control theory of abolishing the local micturition reflex arc...

INTRODUCTION: Primary nocturnal enuresis is one of the sleep related phenomena characterized by disruption in the relationship between arousal and urination. Corticotropin-releasing factor (CRF) is a neurohormone released from the paraventricular nucleus of the hypothalamus into the median eminence to elicit release of adrenocorticotrophin from the anterior pituitary. It may act to modulate autonomic function and behavior in concert with the endocrine effects. Conflicting animal studies about the role of CRF in micturition, either facilitating or inhibiting, have been raised...

INTRODUCTION: Primary female bladder neck obstruction is a rare clinical condition characterized by the absence/incomplete bladder neck opening during the voiding phase of micturition. METHODS: We present the cases of two women complaining dysuria, abdominal straining and sensation of incomplete bladder emptying. Videourodynamic evaluation was fundamental for a correct diagnosis. RESULTS: Videourodynamic evaluation showed a high detrusor pressure during emptying phase, partial use of abdominal strain, very low urine flow rate and significant postvoid residual; imaging showed a defect in the physiological funneling of the bladder neck, absent or incomplete...

Differentiated non-invasive diagnostic procedures allow a discrimination between nocturnal enuresis and behavior-linked urinary incontinence in children with daytime symptoms, which are different entities of a pathological pediatric micturition syndrome. The article describes the diagnostic procedure as well as the therapeutic approach to all forms of micturition disorders in childhood. All behavioral, medical and biofeedback therapeutic methods according to the recently published S2k guidelines from the Association of the Scientific Medical Societies in Germany (AWMF) on enuresis and non-organic (functional) incontinence in children and adolescents are mentioned and discussed...

BACKGROUND: Traditional tibial nerve stimulation (TNS) has been used to treat overactive bladder syndrome (OAB), but there are some shortcomings. Thus, a novel alternative is needed for the treatment of OAB. The study investigated the effects of a new type of tibial nerve microstimulator on the micturition reflex in cats. METHODS: An implantable wireless driver microstimulator was implanted around the tibial nerve in 9 α-chloralose anesthetized cats. Cystometry was performed by infusing 0...

OBJECTIVE: Pelvic floor muscle training is effective and necessary in the prevention and treatment of pelvic floor dysfunction during pregnancy and after childbirth. But because of the high prevalence of perineal pain observed in women after childbirth, many women and caregivers fear to start pelvic floor muscle training immediately after childbirth. However, it is unknown whether pelvic floor muscle contractions (PFMC) provoke perineal pain in women shortly after childbirth. Therefore, the main objective is to study whether PFMC performed immediately after childbirth is painful or not...

INTRODUCTION: The brain has two goals: survival of the individual and survival of the species. It ensures that the body resides in safe circumstances and can obtain sufficient drink and food. It also has to produce and protect offspring. Its most important tool is its motor system, which consists of the voluntary and emotional motor systems. AIM: To explain how the brain uses its emotional motor system to control the pelvic organs. METHODS: Anatomic and physiologic data in cats and humans are used to find out how this motor system works and what parts of the brain and brainstem are involved...

REVIEW
Claire McDonald, Kristian Winge, David J Burn
Lower urinary tract symptoms (LUTS) are common in Parkinson's disease (PD), effecting 27-85% of patients with PD. Irritative symptoms predominate and urodynamic studies confirm high prevalence of detrusor overactivity in PD. LUTS are present early in PD and are more common in PD than in age matched controls. The assessment of LUTS in PD is complicated by coexisting bradykinesia and cognitive impairment. Although LUTS become more troublesome as PD progresses it remains unclear if LUTS severity correlates with motor symptoms and/or duration of PD...

PURPOSE OF REVIEW: A specialized epithelial cell with chemosensory properties of taste cells known from the mouth has been newly identified in the urethra and linked to pathogen recognition. We here describe its properties and its link to defence mechanisms, showing parallels to similar sentinel cells in the respiratory and gastrointestinal tract. RECENT FINDINGS: In the urethra, slender epithelial cells with apical microvilli ('brush cells') express bitter and umami taste receptors and the downstream signalling cascade known from oropharyngeal gustation, utilizing it to monitor for bacterial products and bacterial growth facilitating conditions...

INTRODUCTION AND HYPOTHESIS: Disorders of micturition result from a wide variety of conditions and evaluation often involves multiple diagnostic modalities. However, the sensitivity and specificity of these techniques are highly variable and may not always yield a diagnosis. Novel imaging techniques such as ultrasound shear wave elastography may help to improve diagnostic accuracy. METHODS: Continent women were recruited from outpatient gynecology offices from a tertiary medical system...

Treating recurrent vesicovaginal fistula (VVF) is a major clinical problem. We present a technique and special precautions taken during treatment of a small recurrent VVF with the help of combined cystoscopic and/or transvaginal injection of cyanoacrylate in two patients. Except for frequency of micturition in the first patient, postoperative follow-up was uneventful. Endoscopic management with cyanoacrylate is a simple and effective alternative to major reconstructive surgery.
