[Vesicovaginal Reflux and Urocolpos]

OBJECTIVE

Vesico-vaginal reflux (VVR) is defined as the reflux of urine into the vaginal vault during voiding, occasionally seen in pre- adolescent girls. The typical history consists in post voiding leaks in the daytime, that correspond to the progressive urine discharge from the vagina, after it has been filled up during micturition. We intend to show two cases presenting with significant urocolpos.

METHODS

Description of two clinical cases observed in the pediatric urology office.

RESULTS

Clinical case 1.- A 10-year-old girl presented with the complaint of diurnal incontinence (in the immediate post-voiding minutes). The early voiding phase in the cystourethrogram (VCUG) demonstrated progressive gross distension of the vagina (urocolpos) due to retrograde filling as the bladder emptied. The girl was managed with behavioural modifications, and was dry afterwards. Clinical case 2.- A 9-year-old girl presented with history of incomplete voiding. In infancy, she had right-sided vesicoureteral reflux (VUR) and was endoscopically treated at the age of 2. VCUG showed VVR, and no VUR. She was then successfully treated with behavioural modifications. Clinical case 3.- A 10-year-old girl complained of diurnal urinary incontinence, described as post voiding leaks. Again, a VCUG showed VVR and a small urocolpos. After re-education of voiding habits, leaks disappeared, but recurred 6 months afterwards, when she acknowledged no adherence to the therapy.

DISCUSSION

Between 12 to 15% of girls referred to Urological clinics because of urine incontinence present VVR. In the absence of a clear anatomical obstruction, reflux happens as the urine flow encounters a natural obstacle in the labia majora usually in girls that close their legs as they void. Instructions on proper voiding form a key element in the management of VVR, and if not enough, the behavioural modification consists on a reverse position during voiding.

Pre- and postnatal findings in a patient with a novel rec(8)dup(8q)inv(8)(p23.2q22.3) associated with San Luis Valley syndrome

San Luis Valley syndrome, which is due to a recombinant chromosome 8 (SLV Rec8) found in Hispanic individuals from Southwestern United States, is a well-established syndrome associated with intellectual disabilities and, frequently, severe cardiac anomalies. We report for the first time on a Moroccan girl with a recombinant chromosome 8 prenatally diagnosed as SLV Rec8 by conventional cytogenetic studies. At birth, an oligo array-CGH (105 K) defined the breakpoints and the size of the imbalanced segments, with a deletion of ≈ 2.27 Mb (8p23.2-pter) and a duplication of ≈ 41.93 Mb (8q22.3-qter); thus this recombinant chromosome 8 differed from that previously reported in SLV Rec8 syndrome. The phenotypic characteristics associated with this SLV Rec8 genotype overlap those commonly found in patients with 8q duplication reported in the literature. We review SLV Rec8 and other chromosome 8 aberrations and suggest that the overexpression of cardiogenic genes located at 8q may be the cause of the cardiac defects in this patient.
