Extracellular adenosine 5'-triphosphate concentrations changes in rat spinal cord associated with the activation of urinary bladder afferents. A microdialysis study.

Einstein (Säo Paulo); 14 (4), 2016
ABSTRACT Objective To determine adenosine 5’-triphosphate levels in the interstice of spinal cord L6-S1 segment, under basal conditions or during mechanical and chemical activation of urinary bladder afferents. Methods A microdialysis probe was transversally implanted in the dorsal half of spin...

Rate of spontaneous voiding recovery after acute urinary retention due to bed rest in the hospital setting in a non-urological population clinical study of the relationship between lower limbs and bladder function

Int. braz. j. urol; 42 (6), 2016
Abstract Objectives To understand the clinical relationship between lower limbs functions and the recovery of spontaneous voiding after an acute urinary retention (AUR) in older patients admitted to hospitals for non-urological causes using clinical parameters. Materials and Methods 56 adult patients (...

Long term outcome and side effects in patients receiving low-dose I125 brachytherapy: a retrospective analysis

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Objectives: To retrospectively evaluate the disease free survival (DFS), disease specific survival (DSS),overall survival (OS) and side effects in patients who received low-dose rate (LDR) brachytherapy with I125 stranded seeds. Materials and methods: Between july 2003 and august 2012, 274 pat...

Effect of S-methyl-l-thiocitrulline dihydrochloride on rat micturition reflex

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Objective: To evaluate the effect of neuronal nitric oxide synthase on the striated urethral sphincter and the urinary bladder. Materials and Methods: A coaxial catheter was implanted in the proximal urethra and another one in the bladder of female rats, which were anesthetized with subcutaneo...

Hemangiopericitoma de Bexiga: relato de uma patologia rara

Metaplastic Conditions in The Bladder in Patient With Epidermolysis Bullosa

Int. braz. j. urol; 42 (4), 2016
ABSTRACT Epidermolysis bullosa is a rare inherited muco-cutaneous disorder that sometimes presents with genitourinary involvement. Herein we report the case of an 11-year-old girl with a history of junctional epidermolysis bullosa who was admitted with urological symptoms. On cystoscopy, suspected bullou...

Optimal bladder diary duration for patients with suprapontine neurogenic lower urinary tract dysfunction

Int. braz. j. urol; 42 (4), 2016
ABSTRACT Purpose: To identify the minimum bladder diary's length required to furnish reliable documentation of LUTS in a specific cohort of patients suffering from neurogenic urinary dysfunction secondary to suprapontine pathology. Materials and Methods: From January 2008 to January 2014, patients suff...

Sonographic abnormalities in augmented bladder using porcine intestinal submucosa (SIS)

Among the different materials for bladder augmentation, porcine intestinal submucosa (SIS) is the most widely investigated and stands out for its ability as a cell scaffold. In this context, the ultrasound examination allows the detection of changes from the surgical procedure, enabling the early verific...

Can intraurethral stimulation inhibit micturition reflex in normal female rats?

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Objective The study was designed to determine the effect of low frequency (2.5Hz) intraurethral electrical stimulation on bladder capacity and maximum voiding pressures. Materials and Methods The experiments were conducted in 15 virgin female Sprague-Dawley rats (220–250g). The animals...

The influence of distal colon irritation on the changes of cystometry parameters to esophagus and colon distentions

Int. braz. j. urol; 42 (3), 2016
ABSTRACT The co-occurrence of multiple pathologies in the pelvic viscera in the same patient, such as, irritable bowel syndrome and interstitial cystitis, indicates the complexity of viscero-visceral interactions and the necessity to study these interactions under multiple pathological conditions. In the...
