Mayo Clinic Finds Kidney Disease Associated with "Benign" Prostate Obstruction

30.06.2005


Men who experience signs and symptoms of a prostate obstruction resulting from benign prostatic hyperplasia (BPH) are three times more likely than other men to develop chronic kidney disease, according to findings of a Mayo Clinic study published in this month’s edition of Kidney International.



"This is the first study on the topic to sample the general community," says Andrew Rule, M.D., the Mayo Clinic kidney specialist who conducted the study with epidemiologist Steven Jacobsen, M.D., Ph.D.

"Symptomatic and non-symptomatic men were compared, unlike clinical trials and studies in a urology practice, which tend to represent only symptomatic men."


BPH and chronic kidney disease pose significant health problems in older men. Chronic kidney disease (CKD) occurs when the kidneys cannot rid metabolic wastes from the body or maintain the proper fluid and chemical balances. Eventually, the waste builds up and becomes poisonous to the body. Kidney disease can develop rapidly -- in two to three months -- or gradually over decades.

Many risks coincide with the development of CKD. "Several studies show men with chronic kidney disease have increased chance of death, hospitalization and cardiovascular events," says Dr. Rule.

The prostate gland is located just below a male’s bladder and surrounds the top portion of the urethra, the tube that drains urine from the bladder. "Growth of the prostate gland can lead to a bladder outlet obstruction," says Dr. Rule. "An obstruction of the bladder can cause inability to or discomfort in emptying the bladder, a slowed stream of urine, frequent urges to void during the night or an enlarged, damaged bladder."

"We were surprised at how much kidney disease can be attributed to BPH," says Dr. Jacobsen. "An obstruction on the urethra is like a dam on a river -- men can still void, but the constant buildup and pressure will ultimately cause damage." BPH affects about half of men in their 60s and up to 90 percent of men in their 70s and 80s. It is not related to the development of prostate cancer, although causes of BPH tissue growth inside the prostate later in life is unclear. Researchers believe that with age the prostate becomes more susceptible to the effects of hormones, including testosterone.

The most effective way to treat CKD is to care for and manage the underlying disease. "It has been shown that many patients with kidney disease respond to surgical treatments of BPH," says Dr. Rule. "There are also medications to relieve obstructions, by either shrinking the prostate gland or relaxing muscles that contribute to the obstruction."

The recent study surveyed 476 white men, ages 40-79, randomly selected from Olmsted County, Minn. Eventually, the researchers would like to see if similar findings are reproduced among general populations studied at other research centers. Dr. Jacobsen also suggests further research and testing to determine if treating BPH reverses the progression of kidney disease.

Ultimately, the researchers hope the results of the study will encourage both physicians and patients to consider BPH as a factor in kidney disease. "Men with diagnosed BPH may need to be screened to see if this condition is causing kidney damage," says Dr. Jacobsen.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
