The unstable bladder and prostatectomy

D A Price, P D Ramsden, D Stobbart

British Journal of Urology

|December 1, 1980

Summary

This summary is machine-generated.

Prostatectomy improved bladder instability in 41% of men with urinary frequency and urgency within 6 months. Pre-operative voiding pressure over 100 cmH2O predicted a positive outcome for these patients.

Area of Science:

Urology
Nephrology

Background:

Male patients with lower urinary tract symptoms often experience frequency, urgency, and poor stream.
Bladder outlet obstruction and detrusor overactivity (instability) are common causes.
Prostatectomy is a surgical option for these conditions.

Purpose of the Study:

To evaluate the efficacy of prostatectomy in resolving bladder instability.
To identify predictors of successful treatment outcomes.

Main Methods:

Cystometry was performed on 51 male patients with lower urinary tract symptoms.
Twenty-four patients with obstruction and instability underwent repeat cystometry post-prostatectomy.
Pre-operative instability grading and voiding pressures were recorded.

Main Results:

41% of patients achieved bladder stability by 6 months post-surgery.
No patient who became stable reverted.
Pre-operative instability grading and voiding pressure > 100 cmH2O correlated with improved outcomes.

Conclusions:

Prostatectomy can effectively resolve bladder instability in a significant portion of obstructed male patients.
Pre-operative cystometric findings are valuable for predicting treatment success.
Early post-operative stability suggests a durable positive outcome.
