PURPOSE: We proved the accuracy of the transverse diameter of the rectum on ultrasonography as an additional parameter for diagnosing constipation in children with lower urinary tract dysfunction.

MATERIALS AND METHODS: The diameter of the rectum on bladder ultrasonography in a constipated group of patients with dysfunctional voiding was compared to this diameter in a control group of patients with a normal defecation pattern. A total of 49 children were included. Group 1 consisted of 23 ...

OBJECTIVES: Dynamic perineal ultrasonography to assess the function of the pelvic floor muscles in children with micturition complaints shows that many children with daytime incontinence or recurrent urinary tract infections use their pelvic floor paradoxically. They strain when asked to withhold urine, or they have no voluntary control of the pelvic floor muscles at all. The aim of this study was to record the pelvic floor function and evaluate the physical therapy regimens for children ...

PURPOSE: We studied the added value of home uroflowmetry for biofeedback training compared to added attention and standard therapy in a multicomponent behavioral training program for voiding disorders in school-age children. Little is known about the role of biofeedback by home uroflowmetry for dysfunctional voiding due to NNBSD in children.

MATERIALS AND METHODS: A randomized controlled study was conducted at an outpatient pediatric incontinence university clinic from January 2000 to ...

PURPOSE: We determined whether parents of children with overactive bladder and dysfunctional voiding had had similar symptoms in childhood.

MATERIALS AND METHODS: A case-control study was done in parents with and without children with overactive bladder or dysfunctional voiding. All were recruited from an outpatient clinic. Diagnoses in children were made according to the International Children's Continence Society standardization report. Childhood symptoms in parents were assessed by a ...

OBJECTIVE: The purpose of this work was to analyze prospectively the prevalence of behavioral disorders in children with urinary incontinence because of nonneuropathic bladder-sphincter dysfunction before and after treatment for incontinence.

METHODS: A total of 202 children with nonneuropathic bladder-sphincter dysfunction were enrolled in the European Bladder Dysfunction Study, in branches for urge syndrome (branch 1) and dysfunctional voiding (branch 2); 188 filled out Achenbach's ...

OBJECTIVES: To describe the use of colonic washout enemas for persistent constipation in children treated for dysfunctional voiding by cognitive and biofeedback training.

METHODS: We treated 50 children, who had dysfunctional voiding and persistent dilatation of the rectum notwithstanding adequate oral laxatives, with colonic washout enemas. We performed retrograde filling of the rectum with 20 mL/kg water, starting once daily for 2 weeks, then 3 times per week for 6 to 12 ...

OBJECTIVE: To clarify the relationship between disordered defecation and non-neuropathic bladder-sphincter dysfunction (NNBSD) by comparing the prevalence of symptoms of disordered defecation in children with NNBSD before and after treatment for urinary incontinence (UI), and assessing the effect of such symptoms on the cure rate for UI.

PATIENTS AND METHODS: In the European Bladder Dysfunction Study, a prospective multicentre study comparing treatment plans for children with NNBSD, 202 ...

OBJECTIVE: To reassess the incontinence and urge complaints in adults who had undergone inpatient urotherapy during childhood and compare the results with the short-term outcomes.

METHODS: From 1987 to 1990, 95 children (13 boys and 82 girls; age 6-17 years) underwent hospitalized urotherapy to treat functional lower urinary tract symptoms. This group was traced and a questionnaire was administered by telephone. The long-term data on incontinence and urge complaints were compared with ...

OBJECTIVE: To treat enuresis risoria (giggle micturition) by a self-administered electric and imaginary shock and to evaluate the outcome after behavioural therapy.

PATIENTS AND METHODS: Six boys and three girls with enuresis risoria were evaluated and treated. The mean age at referral was 10.4 years (range 5.7-14.2). All children had episodes of involuntary complete bladder emptying triggered by hearty laughter or giggling. The frequency ranged from four times per day to twice a week. ...

OBJECTIVE: To gain insight into the efficacy and safety of urethral de-obstruction in boys with overactive bladder (OAB) complaints refractory to conservative treatment.

MATERIALS AND METHODS: All boys, older than 5 years, referred in 2009 for OAB complaints were included, n = 180. Nine had abdominal or penile pain as predominant complaint. 82% were tertiary referrals after unsuccessful conservative treatment with antimuscarinic medication and/or urotherapy for OAB. In 121, urethral ...

PURPOSE: Until 1986 many urologists performed currently outdated, redundant internal urethrotomy as standard therapy for recurrent urinary tract infection in girls. We describe the results of therapy in patients who became incontinent due to previous internal urethrotomy.

MATERIALS AND METHODS: Between 1986 and 1995, 21 female patients with post-Otis urethrotomy incontinence have presented at our department with combined dysfunctional voiding, recurrent urinary tract infection and ...

AIMS: This study was conducted to try to objectify assessment of pediatric uroflowmetry curves.

MATERIALS AND METHODS: Nine professionals in pediatric incontinence care judged 480 pediatric uroflows. On a 1-5 scale, where 1 = anomalous and 5 = normal, uroflows were assessed on four items: staccato, interrupted, flow time and obstruction. Eighty uroflows were re-evaluated for intra-observer agreement. After staccato and interrupted flow had been defined more sharply, another 100 uroflows ...
