Risk factors for incomplete bladder emptying after midurethral sling
Urology
|December 21, 2013
Summary
Incomplete bladder emptying after midurethral slings (MUS) is common, particularly with retropubic slings, but usually resolves quickly. Preoperative straining is a risk factor.
Area of Science:
- Urology
- Female Pelvic Medicine and Reconstructive Surgery
Background:
- Midurethral slings (MUS) are a common surgical treatment for stress urinary incontinence.
- Incomplete bladder emptying is a potential postoperative complication following MUS procedures.
Purpose of the Study:
- To determine the prevalence and identify risk factors for incomplete bladder emptying after midurethral slings (MUS).
Main Methods:
- A large multicenter trial randomized 597 women to retropubic (RMUS) or transobturator midurethral slings.
- Preoperative data included demographics, voiding symptoms, and urodynamics.
- Incomplete bladder emptying was defined as a postvoid residual >150 mL, assessed via voiding trials.
Main Results:
- At discharge, 19% required indwelling catheterization and 5% intermittent catheterization for incomplete bladder emptying.
- Women receiving RMUS were more likely to experience incomplete bladder emptying (OR 1.79).
- Preoperative straining to void was associated with incomplete bladder emptying (OR 1.75).
Conclusions:
- Incomplete bladder emptying post-MUS is frequent, especially after RMUS, but typically transient.
- Preoperative voiding symptoms like straining are risk factors.
- Urodynamic parameters did not predict incomplete bladder emptying after MUS.

01:21Nursing Assessment of the Genitourinary System I: Health History
822
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
3.6K
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

01:23Urinary Bladder
4.7K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

53
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

9.4K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
