Prostatic Diseases and Male Voiding Dysfunction Ultrasound-Estimated Bladder Weight Predicts Risk of Surgery for Benign Prostatic Hyperplasia in Men Using -Adrenoceptor Blocker for LUTS

BJECTIVES Although invasive and expensive, the pressure-flow study is known as the reference stand the diagnosis of bladder outlet obstruction. We investigated the usefulness of ultras estimated bladder weight (UEBW) as a predictor of the need for surgery for benign p hyperplasia (BPH). ETHODS A total of 97 consecutive male patients 50 years old with lower urinary tract symptoms (LU were prospectively enrolled in this study. The surgery rate was correlated with the UEB results of uroflowmetry, the postvoid residual urine volume, prostate volume, and Interna Prostate Symptom Score. ESULTS Surgery for BPH was performed in 37 of the 97 patients studied. The surgery rate was a with a high UEBW ( 35 g), severe LUTS (International Prostate Symptom Score of 20), a voided volume of 100 mL at free uroflowmetry, and poor uroflow (maximal flow rate o 10 mL/s). Multivariate analysis revealed that severe LUTS and a high UEBW were the risk for surgery for BPH. ONCLUSIONS T h e results of our study have shown that the UEBW can be regarded as a useful parameter patients with LUTS who are at risk of needing surgery for BPH.
