Urinary Bladder01:23

Urinary Bladder

1.4K
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...

The Micturition Reflex01:26

The Micturition Reflex

993
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Urodynamic Studies: Uroflowmetry

461
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

101
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Anatomy of the Genitourinary System II: Bladder and Urethra

198
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...

Urinary Tract Infection IV: Nursing Management01:17

Urinary Tract Infection IV: Nursing Management

83
In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs...

Summary

Preoperative detrusor overactivity and low bladder compliance predict frequent urination after transurethral resection of the prostate for benign prostatic hyperplasia. Urodynamic testing is crucial for predicting outcomes.

Area of Science:

  • Urology
  • Nephrology
  • Surgical Oncology

Background:

  • Benign prostatic hyperplasia (BPH) is common in older men.
  • Transurethral resection of the prostate (TURP) is a standard treatment for BPH.
  • Postoperative frequent micturition can negatively impact quality of life.

Purpose of the Study:

  • To investigate the relationship between preoperative bladder function and frequent micturition after TURP in BPH patients.
  • To identify predictors of postoperative urinary symptoms.

Main Methods:

  • Retrospective study of 80 BPH patients who underwent TURP.
  • Patients categorized by preoperative detrusor overactivity and bladder compliance (low, normal, high).
  • Analysis of postoperative frequent micturition incidence and severity.

Main Results:

  • Higher incidence and scores of frequent micturition in patients with preoperative detrusor overactivity and low bladder compliance.
  • Detrusor overactivity, bladder compliance, maximum cystometric capacity, and maximum flow rate were significant predictors.
  • No significant difference in frequent micturition scores between normal and high bladder compliance groups.

Conclusions:

  • Abnormal preoperative bladder storage (detrusor instability, low compliance) is linked to increased risk of frequent urination post-TURP.
  • Preoperative urodynamic evaluation is vital for predicting and managing postoperative urinary frequency in BPH patients.
