Photoselective Vaporization of the Prostate and Simultaneous Suprapubic Cystostomy for the Treatment of Benign Prostatic Hyperplasia in Patients with Mild to Severe Detrusor Underactivity

摘要

Introduction: This study investigated the clinical efficacy and safety of photoselective vaporization of the prostate (PVP) and simultaneous suprapubic cystostomy for benign prostatic hyperplasia (BPH) in patients with mild to severe detrusor underactivity (DU). Subjects and Methods: Seventy-eight patients with BPH were divided into 3 groups according to the severity of DU: mild DU group, moderate DU group and severe DU group. The preoperative and postoperative data, including the detrusor pressure at maximum flow (Pdetmax), bladder compliance, maximum urinary flow (Qmax), postvoid residual urine (PVR) values, International Prostate Symptom Score (IPSS) and quality of life (QoL) were evaluated. Results: The therapeutic effectiveness including cure and improvement in mild and moderate DU group was significantly higher than that of the severe group. Compared to the preoperative values, Pdetmax, bladder compliance, Qmax, PVR, IPSS and QoL scores at 12 months postoperatively had significantly improved. In addition, the above parameters at 12 months postoperatively in the mild or moderate DU group had significant difference compared to the severe DU group. Conclusion: PVP and simultaneous suprapubic cystostomy seem to be an appropriate treatment modality in BPH patients with mild and/or moderate DU as well as in patients with severe DU and slightly reduced bladder compliance.
