Retrospective observation of the efficacy and safety of prostatic artery embolization combined with transurethral resection of the prostate and simple transurethral resection of the prostate in the treatment of large (> 100 mL) benign prostatic hyperplasia

Purpose To retrospectively compare the efficacy and safety of prostatic artery embolization (PAE) combined with transurethral resection of the prostate (TURP) and simple TURP in treating large (> 100 mL) benign prostatic hyperplasia (BPH). Methods We retrospectively analyzed the clinical data of 13 and 17 patients with large BPH who underwent TURP and PAE + TURP, respectively, from January 2016 to January 2020. The changes in various indices before and after surgery were compared between the two groups. Results In the PAE + TURP group, the operation time (OT), intraoperative blood loss (BL), postoperative bladder flushing time (PBFT), and postoperative catheter retention time (PCRT) were lower, and the speed of the excised lesion (SEL) was higher than that in the TURP group ( P < 0.05). Following-up for 12 months, the prostatic volume (PV), maximum urinary flow rate (Qmax), postvoid residual volume (PVR), International Prostate Symptom Score (IPSS), quality of life (QoL) score, total prostate-specific antigen (T-PSA), and free prostate-specific antigen (F-PSA) in each group improved as compared to before the surgery ( P < 0.05), and the above improved indicators, IPSS ratio, and obstructive symptoms in the PAE + TURP group were higher than those in the TURP group ( P < 0.05). The incidence of postoperative complications in the PAE + TURP group was lower than that in the TURP group. We obtained the pathological picture of a prostate biopsy after PAE for the first time. Conclusion Compared to TURP alone, PAE + TURP should be promoted, because of its greater efficacy and safety in treating large BPH and fewer post-surgical complications. Graphic abstract
