Summary
Sacral neuromodulation (SNM) effectively restores bladder voiding function in patients with bladder voiding disorders. While SNM shows significant efficacy, potential side effects like pain require careful management and further research for predictive factors.
Area of Science:
- Urology
- Neurology
- Medical Devices
Context:
- Bladder voiding disorders affect a significant patient population.
- Sacral neuromodulation (SNM) is an established treatment option.
- Long-term outcomes and patient selection require further investigation.
Purpose:
- To evaluate the long-term experience and efficacy of SNM for bladder voiding disorders.
- To identify patient characteristics and urodynamic factors influencing SNM success.
- To report on the incidence and management of SNM-related side effects.
Summary:
- A retrospective analysis of 122 patients treated with SNM for bladder voiding disorders between 1998 and 2022.
- Significant improvement in spontaneous micturition rates (34% to 92%) was observed, particularly in patients with sphincter hypertonia.
- High rates of side effects (52% at 5 years), primarily device-related pain, were reported, often resolved with medical or surgical intervention.
Impact:
- SNM demonstrates considerable effectiveness in improving bladder voiding function.
- Understanding urodynamic mechanisms and etiology may optimize SNM settings and patient selection.
- Further multi-center data are crucial for establishing reliable predictive factors for SNM success.

01:26The Micturition Reflex
699
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...

01:23Urinary Bladder
871
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...

01:19Urodynamic Studies: Uroflowmetry
56
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...

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
126
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...

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...
