Congenital urethral valves: findings in 73 children. Objective. To inventory symptoms of children with urethral valves, and their prognosis. Design. Descriptive, Setting. Department of paediatrics and urology, University of Nij megen. Methods. Symptoms were evaluated from clinical data and interviews of the parents of 73 patients. The glomerular filtra­ tion rate (GFR) was calculated from the s...

PURPOSE Anterior urethral valves (AUVs) is an unusual cause of congenital obstruction of the male urethra, being 15-30 times less common than posterior urethral valves (PUVs). It has been suggested that patients with congenital anterior urethral obstruction have a better prognosis than those with PUV, with less hydronephrosis, and a lower incidence of chronic renal insufficiency (5 vs. 30%). Th...

Urethral obstruction, partial or complete blockage of the urethral lumen, is a serious condition, which often results in rupture of the bladder or extra-pelvic urethra in ruminants. It occurs almost exclusively in the male in which the structure is obliged to follow an extremely tortuous course [5]. Rupture of the urethra and bladder, in turn, results in infiltration of urine into the connectiv...

Urgency is the core symptom of the overactive bladder symptom complex, but the underlying mechanisms are not fully understood. Clinical findings have led to the assumption that bladder outlet obstruction (BOO) caused by benign prostatic enlargement (BPE) induces storage symptoms and detrusor overactivity. Presumably, BOO by BPE accounts for urgency; however, urgency is not always caused by BOO....

Rett Syndrome (RTT) is a neurodevelopmental disorder characterized by loss of acquired skills during development, autonomic dysfunction, and an increased risk for premature lethality. Clinical experience identified a subset of individuals with RTT that present with urological dysfunction including individuals with frequent urinary tract infections, kidney stones, and urine retention requiring f...

Urodynamic investigation becomes increasingly important in the diagnosis of bladder outflow obstruction in patients with benign prostatic hyperplasia. To date, different methods for evaluation of the pressure-flow relationship and quantification of the grade of obstruction are available. Models for pressure-flow analysis are briefly explained. The variability of the parameters is investigated b...

PURPOSE OF REVIEW The pathophysiological mechanisms of female voiding phase dysfunction are poorly understood, and there are neither standard definitions nor guidelines for diagnosis and treatment. The aim of this review is to present up-to-date data and controversies associated with non-neurogenic female voiding dysfunction. RECENT FINDINGS Conceptually, voiding phase dysfunction may have bl...

Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral rare, with approximately only 120 cases reported the literature. These often occur third and fourth decades life but rare menopausal patients. In general, treatment involves surgery, three recurrence reports Description: a case report on 56-year-old woman; pati...
