Abstract

Purpose: Transrectal ultrasonography (TRUS) is a non-invasive modality widely used in urology on an outpatient basis to measure the volume and anatomical structure of the prostate. However, the prostate volume measured by TRUS often varies from test to test. The aim of this study was to determine the clinical significance of the different shapes of the prostate, as shown by TRUS before and after transurethral resection of the prostate (TURP). Materials and Methods: We evaluated 103 patients who underwent TURP. TRUS was performed preoperatively, and the International Prostatic Symptom Score (IPSS) and quality of life (QoL) were assessed preoperatively and at 6 months postoperatively. Patients were classified into two groups: patients with a bilaterally enlarged transitional zone were assigned to group A, and those with a protruding retrourethral zone were assigned to group B. Results: There were no statistically significant differences between the two groups in preoperative variables. However, postoperative IPSS scores were lower in group A than group B (9.87±6.15 vs. 13.18±8.07, p=0.02). With regard to postoperative IPSS scores relative to preoperative IPSS scores, both groups showed a significant decrease, but group A experienced a significantly greater decrease than group B (13.43±7.47 vs. 8.67±8.33, p=0.005). Conclusions: Patients with a prostate protruding into the bladder have less of a decrease in their IPSS scores after TURP, compared to patients that do not have prostate protrusion, meaning that patients with protrusion experience less symptomatic relief.
