a 6-year-old male crossbred dog was referred to the veterinary medical teaching hospital of islamic azad university of karaj with the history of abdominal distention, rectal tenesmus and stranguria. abdominal radiographs and ultrasonography indicated large distended urinary bladder and prostatic enlargement. ecg showed temporary episodes of atrial standstill. the only abnormalities detected by ...

PURPOSE We investigated the relationship between ultrasound estimated bladder weight/corrected ultrasound estimated bladder weight and the bladder outlet obstruction index derived from pressure flow study to evaluate its diagnostic efficacy to predict bladder outlet obstruction. MATERIALS AND METHODS A total 193 men older than 50 years with lower urinary tract symptoms were enrolled in this s...

IntroductionFetal bladder outlet obstruction (or lower urinary tract [LUTO]) is most commonly caused by posterior urethral valves and atresia can lead to abnormal renal development pulmonary hypoplasia. It associated with a high rate of perinatal morbidity mortality.DefinitionPrenatally detected LUTO occurs because blockage in the (the outlet) developing fetus leads megacystis, thickened wall, ...

Recent work has uncovered a role of the microRNA (miRNA) miR-29 in remodeling of the extracellular matrix. Partial bladder outlet obstruction is a prevalent condition in older men with prostate enlargement that leads to matrix synthesis in the lower urinary tract and increases bladder stiffness. Here we tested the hypothesis that miR-29 is repressed in the bladder in outlet obstruction and that...

The prevalence of bladder outlet obstruction in women is unknown and most probably has been underestimated. Moreover, there are no standard definitions for the diagnosis of bladder outlet obstruction in women. Our study was conducted to define as well as to examine the clinical and urodynamic characteristics of bladder outlet obstruction among women referred for evaluation of voiding symptoms. ...

PURPOSE We quantified the physiological variability of clinical and pressure-flow study variables in patients with symptomatic benign prostatic enlargement. MATERIALS AND METHODS Symptom scores were measured, and advanced urodynamic studies with pressure-flow analysis were performed in 178 patients before and 6 months after a period a watchful waiting. RESULTS Patients without bladder outle...

DOI: 10.21276/sjams.2017.5.9.36 Abstract: The diagnosis and management of bladder outlet obstruction among postmenopausal patients is a complex process with various modalities available for its diagnosis. Cystourethroscopy is an important tool for the same and we intend to study if it is enough in the diagnosis of the presence and degree of bladder outlet obstruction in post-menopausal female p...

PURPOSE We attempted to improve the method of objective clinical evaluation of patients with benign prostatic enlargement and lower urinary tract symptoms. MATERIALS AND METHODS We compared the results of free uroflowmetry and transrectal ultrasound prostate size determination with those of pressure-flow analysis of bladder outlet obstruction in 871 consecutive elderly men. RESULTS Maximal ...

A 37-year-old male patient presented to the emergency department with fever, gross hematuria, and irritative lower urinary tract symptoms. Investigations revealed the presence of a large left bladder diverticulum superior and lateral to the left ureteral orifice without bladder outlet obstruction. Bladder diverticula in adults almost always present in the setting of bladder outlet obstruction. ...

Partial bladder outlet obstruction causes prominent morphological changes in the bladder wall, which leads to bladder dysfunction. In this paper, we demonstrate that polarized light imaging can be used to identify the location of obstruction induced structural changes that other imaging modalities fail to detect. We induced 2-week and 6-week partial outlet obstruction in rats, harvested obstruc...
