We are all human beings but let’s face it, our anatomy is not the same. Men and women experience gender-specific challenges when it comes to urological complications and there are differences that need to be taken into account when addressing these problems.
For many women, urinary tract infection (UTI) is a recurring nightmare. For example, about 50% of all women experience at least one UTI during their lifetime and the risk that women suffer a UTI is 3-4 times greater than for men. Women are more predisposed to UTI for anatomical reasons, such as a short urethra (the longer male urethra facilitates bacteria washout) and close proximity to other bacterial reservoirs in the rectum and vagina.
A new randomized controlled study shows that the solution may be easier than we think. Researchers found that an increased fluid intake can decrease occurrence of UTI. In fact, in women who raised their daily fluid intake from 1.1 to 1.7 liters per day, urine production went up, number of voidings increased (from 5-6 to 8 times per day), and the incidence of UTI was reduced by almost half (3.2 vs 1.7 events per year). There was also an increase in time between UTIs (84 vs 142 days) in those with increased fluid intake.
Another way to avoid UTI is to consider catheter choice following for example gynecological surgery. A new meta-analysis looked at 15 trials and concluded that there is a 279% higher risk of symptomatic UTI associated with indwelling catheter use compared to intermittent catheter use. Intermittent catheterization has also shown to provide benefits when considered after radical hysterectomy.
In men there is a different story. Just as among women, many suffer from lower urinary tract symptoms, but the profile is different. Men’s urinary problems are often linked to voiding problems related to an enlarged prostate and/or stricture disease. Nocturia (the need to void at night) has been reported as the single most common symptom among men with lower urinary tract symptoms.
A new study has explored the use of intermittent catheterization/dilatation therapy following stricture surgery. It seems that this therapy can provide quality of life gains without adding too much inconvenience.
When it comes to intermittent catheterization in men, recently published real world evidence suggests that specific catheter features can improve satisfaction and adherence to the therapy. Ultimately, this means that the catheter you choose can be a decisive factor for obtaining optimal clinical outcomes and minimal complications with intermittent catheterization.
