Yen-Chang Chen, Jia-Fong Jhang, Yung-Hsiang Hsu, Hann-Chorng Kuo
Two 31-year-old women who had abused ketamine, 1 for 8 years and 1 for 5 years, presented with ketamine-induced vesicopathy with urinary frequency, decreased bladder capacity, and detrusor overactivity. An enterocystoplasty was performed in both cases. The pathology of the urinary bladders in both women showed ulcerative cystitis and fibrinoid necrosis of vessels; the latter was confirmed by Masson trichrome staining. Fibrinoid necrosis of vessels is a kind of immune complex-mediated vasculitis that induces the release of inflammatory mediators, with subsequent thrombosis, ischemic injury, and eventual tissue necrosis in localized areas, the so-called Arthus reaction...

OBJECTIVE: Lower urinary tract symptoms (LUTS) in males can reduce patients' quality of life (QoL) and affect sexual function and satisfaction. Although this has been documented in the US, Canada, Germany, Italy, UK, and Sweden, data are limited on the effects of LUTS on QoL and sexual function in Asian men. The present subgroup analysis of an Internet-based survey correlated the incidence of male LUTS by severity and category with self-assessed QoL and sexual function and satisfaction measures...

OBJECTIVE: Mirabegron is widely considered as an effective and safe drug for patients with overactive bladder (OAB). However, there is no evidence regarding the efficacy of mirabegron in human T cell lymphotropic virus-1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients with OAB symptoms. The aim of the present study was to clarify the efficacy of mirabegron in HAM/TSP patients with OAB symptoms. METHODS: The present study evaluated the efficacy of mirabegron treatment (50 mg, once daily) in nineteen HAM/TSP patients with OAB symptoms by assessing subjective symptoms using the overactive bladder symptom score (OABSS) and International Prostate Symptom Score (IPSS) before and 12 weeks after administration...

Acromegaly is a rare disease associated with an increased risk of prostate enlargement. Severe prostate enlargement with severe lower urinary tract symptoms (LUTS) in an acromegalic patient is even more uncommon. Herein we report on a 55-year-old man who was diagnosed with acromegaly and prostate enlargement at 40 years of age. Transsphenoidal surgery, postoperative radiotherapy, and octreotide medical therapy failed to control the acromegaly, and growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels remained elevated...

Bladder pain syndrome (BPS)/interstitial cystitis (IC) is a chronic symptom complex that may cause bothersome storage symptoms and pain or discomfort of the bladder, adversely affecting a patient's quality of life. The etiology of IC/BPS remains unclear, and its cause may be multifactorial. Diagnosis of IC/BPS is based on clinical features, and the possibility of other conditions must be ruled out first. Although no definitive treatment is currently available for IC/BPS, various intravesical therapies are used for IC/BPS, including heparin, hyaluronic acid, chondroitin sulfate, pentosan polysulfate, dimethylsulfoxide, liposomes, and botulinum onabotulinumtoxinA (BoNT-A)...

OBJECTIVE: Stress urinary incontinence (SUI) is a common disease condition in elderly women, suggesting that its etiology may be linked to aging. To investigate the hypothesis that urethral dysfunction and histopathological changes are possible contributors to SUI in elderly women, several parameters of urethral function, as well as histological parameters, were compared between young and aged rats. METHODS: Virgin female rats were examined at 3 different ages, namely 3, 12, and 24 months, corresponding to young, middle-aged, and aged rats, respectively...
