The clinical outcome of patients with small prostates treated with transurethral resection for lower urinary tract symptoms due to benign prostatic hyperplasia

Abstract

INTRODUCTION AND OBJECTIVES: To evaluate the improvement of uroflowmetry parameters in patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) and had transurethral resection of prostate (TURP) as their treatment, in relations to their resected prostatic weight. METHODS: From January 2008 to June 2011, 217 patients underwent TURP for LUTS due to BPH. TURP efficacy was assessed at 3 months using uroflowmetry and post-void residual urine (PVRU). Patients were divided into 2 subgroups according to the resected prostate weight: resected prostate weight <10g and 10g. The post-TURP parameters of the two groups were compared. RESULTS: Results: From this cohort, 58 (26.7%) and 159 (73.7%) patients had resected prostate weight <10g and 10g respecti vely. There was no significant difference in patient age, preoperative Qmax and PVRU between the two groups. After TURP, there was significant difference of Qmax improvement ( mean Qmax improvement : Group A vs Group B; 5.05ml/s vs 9.51ml/s p=0.003); and PVRU improvement ( mean PVRU improvement : Group A vs Group B ; 92.1ml vs 168.6ml p=0.001) CONCLUSIONS: There is statistically significant inferiority on improvement of flow rate and postvoid residue volume in patient with small resected volume.
