Artificial urinary sphincter placement significantly reduces bladder neck contracture recurrence in male cancer survivors with stress urinary incontinence. This effective treatment for recurrent bladder neck contracture should not be delayed.
Area of Science:
- Urology
- Oncology
- Medical Devices
Background:
- Stress urinary incontinence and recurrent bladder neck contracture pose a management challenge for male cancer survivors.
- There is a lack of consensus regarding the optimal management strategy for these conditions.
Purpose of the Study:
- To evaluate the impact of artificial urinary sphincter (AUS) placement on the recurrence of bladder neck contracture (BNC) in prostate cancer survivors experiencing stress urinary incontinence (SUI).
Main Methods:
- A retrospective analysis of an institutional database was conducted.
- Men with SUI and at least one BNC intervention were divided into AUS placement and non-AUS groups.
- Multivariable conditional survival analysis assessed the effect of AUS on BNC recurrence-free survival.
Main Results:
- The study included 118 patients in the AUS group and 88 in the non-AUS group.
- AUS placement was associated with a 61% reduction in BNC re-intervention rates (HR 0.39, P < .01).
- The AUS group had a lower re-intervention rate, even after accounting for prior interventions and risk factors.
Conclusions:
- Artificial urinary sphincter placement is linked to a decreased rate of bladder neck contracture re-intervention.
- AUS implantation should not be postponed or avoided in patients with existing bladder neck contracture.

Urinary Bladder
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 Reflex
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...
