Purpose:

Benign prostatic hyperplasia (BPH) is one of the most prevalent diseases in aging man, which related to lower urinary tract symptoms. Postvoid residual volumes (PSV) is an important urological parameter and reported as the risk factor of urinary tract infection. One of the goals of transurethral procedures, including transurethral resection of the prostate (TURP) and laser prostatectomy (LasP) is to reduce the PSV. However, there are lack of pre-operative predictive factors related to post-operative PSV. Here, we studied the patients’ preoperative parameter and identified the key factors related to post-operative PSV.

Materials and Methods:

Patients with BPH who underwent TURP or LasP at Chang Gung Memorial Hospital, between December 2015 and January 2017 were included for the study. Voided volume less than 150ml was excluded. Mann-Whitney U Test, Spearman’s correlation and Quantile regression was used for correlation analysis between pre-operative parameter and post-operative PSV.

Results:

A total of 93 patients who received transurethral procedures were enrolled. Multivariable quantile regression showed elderly (regression coefficient, 0.94; 95% CI, 0.07 to 1.81; P = 0.04), elevated prostate specific antigen (PSA) (regression coefficient, 3.18; 95% CI, 2.40 to 3.96; P = 0.00) and preoperative bacteriuria (regression coefficient, 39.78; 95% CI, 8.94 to 70.61; P = 0.01) were significantly correlated with increasing post-operative post-void residual urine volume.

Conclusion:
