PURPOSE: Radiotherapy is effective in the treatment of tumors in the pelvic area but is associated with side effects such as cystitis and proctitis. Hyperbaric Oxygen Therapy (HBOT) has emerged as a treatment modality for radiation-induced side effects. In a rat model for radiation cystitis, we studied the effects of HBOT on oxidative stress and pro-fibrotic factors. MATERIALS AND METHODS: Sedated Sprague-Dawley rats underwent bladder irradiation of 20Gy with and without 20 sessions of HBOT during a fortnight...

Endomyocardial fibrosis (EMF) is a neglected restrictive cardiomyopathy of unknown aetiology and unclear natural history, which causes premature deaths in endemic areas. We present the case of a 13-year-old boy from a highly endemic area, presenting with concurrent signs of chronic EMF and severe hypereosinophilia associated with active schistosomal cystitis. We discuss the possible role of this parasitic infection in determining the progression of EMF in endemic areas for both conditions.

Long-term ketamine abuse has been shown to affect the lower urinary tract and result in interstitial cystitis-like syndrome. However, the causative mechanism of ketamine-induced dysfunction remains unclear. The present study aimed to investigate the physiological, histological and molecular changes on ketamine‑associated cystitis (KC) in a mouse model. Both male and female Balb/c mice were separately distributed into the control group (normal saline) and ketamine group, which received ketamine hydrochloride (100 mg/kg/day) daily by intraperitoneal injection for a total period of 20 weeks...

PURPOSE: Xerostomia is a common radiation sequela, which has a negative impact on the quality of life of patients with head and neck cancer. Current treatment strategies offer only partial relief. Botulinum toxins (BTX) have been successfully used in treating a variety of radiation sequelae such as cystitis, proctitis, fibrosis, and facial pain. The purpose of this study was to evaluate the effect of BTX on radiation-induced salivary gland damage. METHODS AND MATERIALS: We used a previously established model for murine salivary gland irradiation (IR)...

BACKGROUND: Radiotherapy plays a substantial role in the treatment of malignancies. The side effects and long-term sequelae of radiotherapy are manifold and depend on the single doses and the total dosage, the time interval between two doses, the size of the irradiated tissue area and the radiation sensitivity of individual tissues. The urological complications following radiotherapy include inflammatory alterations of the bladder (radiation-induced hemorrhagic cystitis), fibrosis with subsequent radiogenic shrunken bladder, stenosis of the ureter and formation of secondary retroperitoneal fibrosis...

PURPOSE: Urinary stasis is a risk factor for recurrent urinary tract infection (UTI). Homozygous mutant Megabladder (Mgb-/-) mice exhibit incomplete bladder emptying as a consequence of congenital detrusor aplasia. We hypothesize that this predisposes Mgb-/- mice to spontaneous and experimental UTI. METHODS: Mgb-/-, Mgb+/-, and wild-type female mice underwent serial ultrasound and urine cultures at 4, 6, and 8 weeks to detect spontaneous UTI. Urine bacterial isolates were analyzed by Gram stain and speciated...

BACKGROUND: Urethral pain syndrome is a symptom complex including dysuria, urinary urgency and frequency, nocturia and persistent or intermittent urethral and/or pelvic pain in the absence of proven infection. These symptoms overlap with several other conditions, such as interstitial cystitis bladder pain syndrome and overactive bladder. Urethral pain syndrome may occur in men but is more frequent in women. DIAGNOSTIC: The exact etiology is unknown but infectious and psychogenic factors, urethral spasms, early interstitial cystitis, hypoestrogenism, squamous metaplasia as well as gynecological risk factors are discussed...

Ketamine abusers have greatly increased in number worldwide during recent years. The consumption of ketamine has increased, as have the number of published accounts of devastating urological sequelae. However, the mechanism of ketamine-associated urinary tract dysfunction remains unclear. This study was to evaluate the ketamine dose-dependency of ketamine-induced cystitis (KC) in a rat model. A total of 42 Sprague-Dawley rats (female, 10-week-old) were used. Each of the 7 KC rat models were induced by 1, 5, 10, 25 and 50 mg/kg ketamine intravenous injection for two weeks...

Ketamine abusers develop severe lower urinary tract symptoms. The major aims of the present study were to elucidate ketamine-induced ulcerative cystitis and bladder apoptosis in association with oxidative stress mediated by mitochondria and the endoplasmic reticulum (ER). Sprague-Dawley rats were distributed into three different groups, which received normal saline or ketamine for a period of 14 or 28 days, respectively. Double-labeled immunofluorescence experiments were performed to investigate tight junction proteins for urothelial barrier functions...

Skeletal muscle injuries repair typically is an overlapping event between inflammation and tissue repair. Our previous study has demonstrated that activation of cannabinoid receptor type 2 (CB2R) by JWH-133 alleviates fibrosis in the repair of rat skeletal muscle contusion. Meanwhile, accumulated data show that CB2R stimulation exerts anti-inflammatory property in sepsis and cystitis. However, the effects of CB2R on inflammatory cytokines in response to the repair of skeletal muscle contusion are still unknown...

The number of ketamine abusers has increased significantly recently. Ketamine abusers exhibit urinary frequency, urgency, and at times urinary incontinence. Our aim was to investigate the role of transcription factor NF-κB and cyclooxygenase (COX)-2 in ketamine-induced cystitis. Sprague-Dawley rats were distributed into three groups, which received saline or treatment with ketamine or ketamine combined with a Cox-2 inhibitor (parecoxib). In addition, the toxic effect of ketamine and its metabolites were examined by primary urothelial cell culture...

Radiotherapy is one of the main methods of cancer treatment alone or in combination with chemotherapy. It is applied in about 60% of oncological patients. However, in spite of its clinical usefulness, radiotherapy is associated with a high risk of radiation-induced side effects, including dermatitis, enteritis, cystitis, pericarditis, pneumonia or depression, sexual function disorders, cardiomiopathy, coronary heart disease, anomalies of heart valves and development of second malignant tumor. The early diagnosis and proper treatment of radiation-induced side effects have a major impact on patients` quality of life and future prognosis...

Purinergic signalling is involved in a number of physiological and pathophysiological activities in the lower urinary tract. In the bladder of laboratory animals there is parasympathetic excitatory cotransmission with the purinergic and cholinergic components being approximately equal, acting via P2X1 and muscarinic receptors, respectively. Purinergic mechanosensory transduction occurs where ATP, released from urothelial cells during distension of bladder and ureter, acts on P2X3 and P2X2/3 receptors on suburothelial sensory nerves to initiate the voiding reflex, via low threshold fibres, and nociception, via high threshold fibres...

PURPOSE: Ureteral loss represents a surgical challenge to provide low pressure drainage while avoiding urinary stasis and reflux. The ideal replacement should optimize drainage while minimizing absorption, allowing for ureteral repair of varied lengths and locations with maximal preservation of the urinary tract. We reviewed our experience with ureteral repair, focusing on the use of reconfigured intestine. We report what is to our knowledge the novel use of reconfigured intestine as an onlay flap on the preserved ureteral segment and as a circumferential interpositioned segment...
