Multicenter Randomized Controlled Trial of ThuLEP Versus ThuLEP Combined With Bladder Neck Incision in Patients With Small-Volume Benign Prostatic Hyperplasia

With the increasing degree of population aging, the number of patients undergoing surgical treatment for benign prostatic hyperplasia (BPH) is steadily rising. Among them, patients with small-volume prostates (≤30 mL) represent a distinct clinical subgroup. This population has several unique characteristics: 1. Approximately 17.5% of patients show suboptimal postoperative outcomes. 2. The incidence of postoperative bladder neck contracture (BNC) is relatively high, reaching up to 19.3% in some reports. In addition, the pathophysiological mechanisms of small-volume BPH are different from those of larger prostates. These include increased fibrotic tension of the bladder neck and bladder neck elevation. At present, there is no clearly established surgical approach specifically designed to further improve postoperative outcomes or effectively prevent bladder neck contracture in patients with small-volume BPH. This study primarily compares the safety and efficacy of transurethral thulium laser enucleation of the prostate (ThuLEP) versus ThuLEP combined with bladder neck incision in the treatment of small-volume benign prostatic hyperplasia (BPH), with the aim of further optimizing surgical management strategies for small prostates and reducing the incidence of postoperative complications.

Study on the Effectiveness of Tranilast in the Treatment of Medium to Large Volume Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH) is one of the most common urinary and reproductive system diseases in elderly men. The preliminary research of the research group found that mast cells are cells that promote the progression of BPH, and the commonly used mast cell membrane stabilizer and TGF - β pathway inhibitor tranilast significantly inhibited the increase in prostate volume in animal experiments, which is considered to have potential applications in the treatment of BPH. This study plans to include 30 patients with medium to large volume BPH and experimentally explore the efficacy and safety of tranilast in the treatment of medium to large volume BPH.
