Study of first-time mums provides reassurance for pregnant women with bladder problems


Women going through their first pregnancy find overactive bladder problems very stressful, but problems reduce considerably three months after childbirth, according to research in the latest BJU International.

Researchers from the University Medical Centre in Utrecht, Netherlands, studied 344 women, asking them to complete questionnaires when they were 12 and 36 weeks’ pregnant and three and 12 months after delivery.

They found that just over 50 per cent of first-time mothers experienced overactive bladder (OAB) symptoms when they were 12 weeks’ pregnant. These included 3.5 per cent who had the added problem of incontinence when they needed to empty their bladder urgently

The number suffering OAB and incontinence at 36 weeks increased to 15 per cent, but fell back to 3.5 per cent at three and 12 months after delivery.

A further eight per cent of new mums still had OAB without incontinence at three and 12 months after delivery.

Women with the added problem of incontinence felt it had an adverse effect on their quality of life both during and after pregnancy, with mobility and embarrassment heading their list of concerns. These issues were still present a year after delivery, but at a much lower level.

“The physical reasons why pregnant women experience overactive bladder symptoms is still not clear” says lead author Dr Henriette Van Brummen.

“It is possibly caused by factors such as pressure from the uterus on the bladder, altered urine production and a change in bladder capacity during pregnancy.

“What is clear, however, is the effect that it can have on some women’s quality of life. It’s an issue that healthcare professionals need to address when they deal with pregnant women and those who have recently delivered, as it can cause real problems and distress, especially when OAB is accompanied by incontinence.”

All the women who took part in the study were first-time mothers who were pregnant with a single child and in good health. Just under two-thirds (65 per cent) had a normal vaginal delivery, 19 per cent needed some assistance and the remainder had elective or emergency Caesareans.

They were recruited from 10 midwifery practices in the Netherlands.

“There are a number of steps that women can take to control or improve an overactive bladder, including pelvic floor exercises to improve their muscle control” adds Dr Van Brummen.

“Further research is needed to examine the effect of bladder training on OAB symptoms during pregnancy and whether combining behavioural and drug treatment after childbirth will result in better outcomes than either therapy alone.”

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
