Postpartum urinary retention: an expert review.

Postpartum urinary retention is a relatively common condition that can have a marked impact on women in the immediate days following childbirth. If left untreated, postpartum urinary retention can lead to repetitive overdistention injury that may damage the detrusor muscle and the parasympathetic nerve fibers within the bladder wall. In rare circumstances, postpartum urinary retention may even lead to bladder rupture, which is a potentially life-threatening yet entirely preventable complication. Early diagnosis and timely intervention are necessary to decrease long-term consequences. There are 3 types of postpartum urinary retention: overt, covert, and persistent. Overt retention is associated with an inability to void, whereas covert retention is associated with incomplete bladder emptying. Persistent urinary retention continues beyond the third postpartum day and can persist for several weeks in rare cases. Recognition of risk factors and prompt diagnosis are important for proper management and prevention of negative sequelae. However, lack of knowledge by providers and patients alike creates barriers to accessing and receiving evidence-based care, and may further delay diagnosis for patients, especially those who experience covert postpartum urinary retention. Nationally accepted definitions and management algorithms for postpartum urinary retention are lacking, and development of such guidelines is essential for both patient care and research design. We propose intrapartum recommendations and a standardized postpartum bladder management protocol that will improve patient outcomes and contribute to the growing body of evidence-based practice in this field.

Factors Associated With a Positive Urine Culture in Women Seeking Urogynecologic Care for Urinary Tract Infection Symptoms.

IMPORTANCE: Urinary tract infections (UTIs) are one of the most common bacterial infections and more frequently affect women than men. OBJECTIVES: Our objective was to determine clinical characteristics associated with a positive urine culture in women seeking treatment for symptoms of UTI. STUDY DESIGN: In this prospective cohort study, women seeking treatment for UTI symptoms were administered the Urinary Tract Infection Symptom Assessment questionnaire at baseline and at the time of culture results. Participants were grouped by history of recurrent UTI (rUTI) based on chart review. Our primary outcome was the proportion of "positive" urine cultures (≥10 3 colony-forming units) compared between rUTI groups. Characteristics were compared and the relative odds of a positive culture were calculated with a logistic regression model. RESULTS: Analyses included 152 women, 79 (52%) with rUTI and 73 (48%) with no history of rUTI. Overall, 90 (59.2%) had a positive culture. Participants with a positive culture were more likely to report history of rUTI ( P = 0.01). There was a 2.45-fold increased adjusted odds of a positive culture in those with a history of rUTI (adjusted odds ratio [aOR], 2.45; 95% confidence interval [CI], 1.34-5.03; P = 0.01) when controlling for confounding variables, including scores on the Urinary Tract Infection Symptom Assessment for frequency (aOR, 0.59; 95% CI, 0.40-0.91), dysuria (aOR, 1.53; 95% CI, 1.10-2.12), and age (aOR, 1.02; 95% CI, 1.01-1.05). CONCLUSIONS: In a cohort of women seeking care for UTI symptoms, older women, those with a history of rUTI and those presenting with dysuria are more likely to have a positive urine culture compared with those with urinary frequency.

Physical Activity and Cerebral Small Vein Integrity in Older Adults.

Identifying promoters of cerebral small vein integrity is important to counter vascular contributions to cognitive impairment and dementia. PURPOSE: In this preliminary investigation, the effects of a randomized 24-month physical activity (PA) intervention on changes in cerebral small vein integrity were compared to those of a health education (HE) control. METHODS: Cerebral small vein integrity was measured in 24 older adults (n = 8, PA; n = 16, HE) using ultra-high field MRI before and at the end of the 24-month intervention. Deep medullary veins were defined as straight or tortuous; percent change in straight length, tortuous length, and tortuosity ratio were computed. Microbleed count and white matter hyperintensities were also rated. RESULTS: Accelerometry-based values of PA increased by 17.2% in the PA group but declined by 28.0% in the HE group. The PA group, but not the HE group, had a significant increase in straight vein length from baseline to 24-month follow-up (P = 0.02 and P = 0.21, respectively); the between-group difference in percent change in straight length was significant (increase: median, 93.6%; interquartile range, 112.9 for PA; median, 28.4%; interquartile range, 90.6 for HE; P = 0.07). Between group differences in other markers were nonsignificant. CONCLUSIONS: Increasing PA in late-life may promote cerebral small vein integrity. This should be confirmed in larger studies.
