Abstract

Objective: The present study assesses the effect of the proportion of tissue resected during transurethral resections of the prostate (TUR-P) on lower urinary tract symptoms (LUTS) and other parameters in patients with a benign prostatic obstruction (BPO).

Materials and methods: Forty-three patients who underwent TUR-P between 2018 and 2021 were assessed prospectively. The patients were divided into two groups according to the percentage of tissue removed (group 1 <30%, group 2 >30% resection). Age, prostate volume, amount of resected tissue, operative time, length of hospital stay, duration of catheterization, International Prostate Symptom Score (IPSS), quality of life score (QoL), maximum urinary flow rate (Qmax), and serum prostate-specific antigen (PSA) (ng/dl) at preoperative and postoperative three months were recorded.

Results: The percentage of tissue removed was 22.2% vs. 48.4% (p = 0.001), IPSS reduction was 77.7% vs. 83.3% (p = 0.048), QoL improvement was 77.2% vs. 84.8% (p = 0.133), Qmax increase was 171.3% vs. 193.5% (p = 0.032), and serum PSA decrease was 56.4% vs. 69.2% (p = 0.049) in groups 1 and 2, respectively. In addition, the operative time was 38.5 vs. 53.6 min (p = 0.001), the length of hospital stay was 2.0 vs. 2.4 days (p = 0.001), and the duration of catheterization average was 4.1 vs. 4.9 days (p = 0.002).

Conclusion: Resections of at least 30% of prostatic tissue can provide a significant improvement in the symptoms and parameters related to benign prostatic obstruction, while resections of less than 30% of prostatic tissue can effectively reduce urinary symptoms and improve the quality of life in older adult patients with comorbidities who require shorter operating times.
