False‐positive pregnancy tests following enterocystoplasty

Abstract

People with major congenital urological or neurological malformations invariably require bladder reconstruction with enterocystoplasty in early childhood. The improvement of the surgical management of these children has reflected significantly on their life expectancy. As a result, more young people with enterocystoplasty are being transitioned to adolescent clinics where they receive the usual counselling about sexual health and pregnancy risks. However, the possibility of false-positive urinary pregnancy tests in these young women remains an overlooked but essential message. The lack of awareness about this fact can result in significant patient anxiety and the potential for unnecessary interventions as exemplified by the three cases we have encountered.

The transition of young adults with lifelong urological needs from pediatric to adult services: An international children's continence society position statement

“…When urine is stored in an intestinal segment, urine pregnancy tests often produce a false positive result (>50%), making serum HCG assay essential to confirm or rule out pregnancy. 49,50 Bacteriuria is classified as symptomatic or asymptomatic, the former often do not need systemic treatment, although increased fluid intake and more frequent emptying are warranted. Symptoms such as fever, malaise or increased incontinence merit early evaluation and culture to allow tailored antibiotic management.…”

Nano-functionalized paper-based IoT enabled devices for point-of-care testing: a review

“…The false-negative result of a home pregnancy test kit causes an increased in pregnancy and sexually transmitted infections (Rahman and Berenson 2013). The home pregnancy test kit's false-positive results lead to significant patient anxiety and pointless interventions (Nakhal et al 2012). It is also observed that the point of care glucose meter's accuracy and clinical performance is hindered at some level of performance (Watkinson et al 2012), through the unsuitable glucose meter may overestimate and underestimate the glucose level, which may hamper the insulin dose of the patient (Perera et al 2011).…”
