| ABSTRACT |
PURPOSE
We evaluated the value of cystometrogram (CMG) as a predictive factor of recurrence of acute urinary retention (AUR) in patients with benign prostatic hyperplasia (BPH).
MATERIALS AND METHODS
26 patients attending the emergency room or out patients clinic with AUR were assessed.
Indwelling catheter was placed in the bladder for 7 days and CMG was performed within 24 hours and 7 days later of AUR.
Recurrence was evaluated by medical records or telephone interview after 1 year of AUR.
RESULTS
CMG findings performed just after AUR were normal (7), decreased capacity (12), large capacity (4), detrusor overactivity (2) and poor compliance (1). These findings were changed by 7-days-inwelling catheterization. Decreased capacity (12) was changed to normal in 5, unchanged in 7.
Large capacity (4) were changed to normal in 3, unchanged in 1, detrusor overactivity (2) and poor compliance (1) were unchanged. AUR was recurred in 5 (33.3%) out of 15 patients who showed normal (7) and turned to normal after 7-days-indwelling catheterization (8), but in 7 (63.6%) out of 11 patients whose CMG was not changed by 7-days-indwelling catheterization.
CONCLUSION
Patients who showed normal at initial CMG and turned to normal CMG after 7-days-indwelling catheter were at low risk of recurrence of AUR. Therefore, CMG performed at the time of AUR may be helpful in the prediction of recurrence of AUR. |
