Characteristics of urinary retention in female inpatients managed with medical treatments

An impacted urethral stone: a rare cause of acute urinary retention in women—case report

Background

Urethral calculi are rare, representing 1–2% of all calculi affecting the urinary tract. Impacted urethra calculi are commoner in males due to anatomical differences between the male and female urethra. The treatment approach is determined by the size and location of the stone, associated anomalies and available facilities.

Case presentation

We present the case of 35-year-old woman who presented with acute urinary retention secondary to an impacted urethral stone. The calculus could not be removed through the external urethral meatus due to the size of the stone. She had cystolithotomy after retrograde manipulation to the bladder. She did well postoperatively. This line of management was based on the size of the stone, and the available facilities which are typical of many hospitals in developing countries.

Conclusions

Urethral calculi are extremely rare in women. The treatment should be individualized.

Urinary retention and catheter use among U.S. female Medicare beneficiaries: Prevalence and risk factors

AIMS

To identify the prevalence of and risk factors for urinary retention and catheterization among female Medicare beneficiaries.

METHODS

We identified women with a diagnosis of urinary retention in a 5% sample of Medicare claims in 2012. Women were categorized into three groups based on the occurrence and duration of urinary catheterization within a 1 year period: 1) no catheterization; 2) short-term catheterization (ie, one or more catheterizations in less than 30 days); and 3) chronic catheterization (catheterizations in multiple 30 day periods within 1 year). We then identified a group of age-matched controls without catheterization or a diagnosis of urinary retention in 2012. Clinical and demographic data were collected for each patient, and risk factors for retention and catheterization were compared across groups. We assessed factors associated with urinary retention using multivariable logistic regression.

RESULTS

We estimated the rate of retention to be 1532 per 100 000 U.S. female Medicare beneficiaries in 2012, with rates of short term and chronic catheterization estimated to be 160 and 108 per 100 000 women, respectively. Prior diagnoses of neurologic condition, urinary tract infection, and pelvic organ prolapse were positively associated with retention and catheterization in multivariable analyses.

CONCLUSIONS

We estimated the prevalence of urinary retention diagnoses among female Medicare beneficiaries to be 1532 per 100 000 women. Retention and catheterization were significantly associated with comorbid disease, with the strongest associations identified with a concomitant diagnosis of neurologic condition, UTI, and POP.

Presentation and prognosis of female acute urinary retention: Analysis of an unusual clinical condition in outpatients

OBJECTIVES

Acute urinary retention (AUR) in females is a poorly defined condition with undetermined epidemiology. This study aimed to evaluate female AUR in an outpatient population.

PATIENTS AND METHODS

One hundred and thirty-eight adult female outpatients who presented to the emergency room with symptoms of urinary retention were retrospectively analyzed. The women who were ultimately diagnosed with true, complete AUR were systematically reviewed for clinical characteristics and management.

RESULTS

In this outpatient cohort with urinary retention complaints, only 23% of the patients were diagnosed with objective AUR. Detailed medical and urological history in addition to urogenital, neurological, and pelvic examinations was essential; urine analysis and pelvic ultrasonography were necessary as baseline investigations. Further radiological and urodynamic tests were required in a minority. Specific etiology was established in 77% of the patients, whereas there was more than one probable cause in 16% of the patients, and no specific cause was found in 6.5% of the patients. Bladder decompression and correction of the underlying cause helped 92.6% of the reviewed patients to eventually achieve spontaneous micturition.

CONCLUSIONS

The proportion of true, complete AUR among female outpatients presenting to the emergency department was 23% following urological evaluation. Acute condition was resolved by urgent catheterization in all, and the majority of women had eventually resumed spontaneous voiding.
