Abstract

Abstract:

Objective

To investigate the effect of prostate volume on the outcomes of transurethral resection of the prostate (TURP).

Methods

A retrospective study was conducted to summarize the cases who received TURP for BPH from January 2012 to July 2014. These patients were divided into three groups according to different prostate volume (PV) (Group A: PV<40 ml; Group B: PV=40~80 ml; Group C: PV>80 ml). The international prostate symptom score (IPSS), qulity of life score(QOL), maximum urine flow(Qmax), average flow rate (Qave), residual urine volume (RUV), prostate-specific antigen (PSA) and the postoperative complications in all patients were compared between pre- and post-surgery.

Results

Group A: 51 patients, (71±10) years old, Group B: 107 patients, (71±9) years old, Group C: 62 patients, (72±7) years old. No statistically significant differences were observed on all indicators of preoperative and complications after TURP(P>0.05). All patients urination improved after surgery, but among the three groups, only the Qmax and Qave changes were statistically significant (P<0.05), no significant difference between the IPSS, QOL and RUV changes (P>0.05).

Conclusions

Prostate volume does not affect the choice of TURP, also does not affect the improvement of dysuria symptoms and quality of life, but urinary flow rate improvement was significant for moderate benign prostatic hyperplasia (PV=40~80 ml).
