Urinary Bladder01:23

Urinary Bladder

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...

Urodynamic Studies: Uroflowmetry

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...

Summary

Intravesical electrotherapy significantly increased bladder capacity and improved compliance in most patients with neurogenic bladder. This safe and effective treatment also enhanced bladder sensation for many, aiding timed voiding.

Area of Science:

  • Urology
  • Neuroscience
  • Biomedical Engineering

Background:

  • Intravesical electrotherapy has demonstrated efficacy in enhancing bladder capacity and compliance.
  • Neurogenic bladder presents challenges in bladder management and requires effective therapeutic interventions.

Purpose of the Study:

  • To evaluate the long-term outcomes of intravesical electrotherapy in patients with neurogenic bladder over a 22-year period.
  • To assess the impact of this therapy on bladder capacity, compliance, storage pressure, and sensation.

Main Methods:

  • A retrospective review of 405 patients who underwent intravesical electrotherapy.
  • Cystometrograms were performed pre- and post-therapy to measure bladder capacity and pressure.
  • Patient-reported bladder filling sensation was assessed.

Main Results:

  • Of 372 evaluated patients, 76.9% experienced a ≥20% increase in bladder capacity post-treatment.
  • In patients with increased capacity, 74.4% maintained normal bladder storage pressures.
  • Improved bladder sensation was achieved in 61.6% of patients, with 33.6% developing sensation during the initial treatment series.

Conclusions:

  • Intravesical electrotherapy is a safe and effective modality for increasing bladder capacity and improving compliance in neurogenic bladder.
  • The therapy can normalize or maintain normal bladder storage pressures.
  • Enhanced bladder sensation in some patients allows for timed voiding based on sensation rather than a fixed schedule.
