Is the amount of resected prostate tissue from transurethral prostatectomy related to outcome?
Objective: To evaluate the amount of resected prostatic tissue from transurethral prostatectomy and the improvement of lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia.
Material and Method: The study includes a prospective analysis of 36 men with benign prostatic hyperplasia. Patients were divided into 2 groups according to the mean percentage of resected tissue: group 1, less than mean percentage, group 2, more than mean percentage. Each patient was evaluated using the International Prostate Symptom Score (IPSS) and Quality of Life (QoL) before surgery, and at 1 and 3 months after surgery.
Result: Mean percentage of resected prostate tissue was 28%. IPSS score had decreased by 17.72 at 1 month and 18.05 at 3 months. Patients in group 2 had an IPSS lower than group 1 by 2.33 (P=0.02). QoL score had decreased by 3.56 at 1 month and 3.47 at 3 months (p<0.001). Patients in group 2 had a QoL lower than group 1 by 0.45 (P=0.03).
Conclusion: The amount of resected prostate tissue had a slight influence on the difference in LUTS and QoL after TURP.
