“…Group of decreased baseline IIEF-5 score covered all 9 surgical approaches with 15 articles. [36][37][38][39][40][41][43][44][45][46][47][48][50][51][52] As shown in Fig. 5 (B-E), patients who underwent TURP (P = 0.188, SMD = 0.06, 95% CI À0.03 to 0.15, I 2 = 32.7%, P = 0.084), PKRP (P = 0.545, SMD = 0.04, 95% CI À0.09 to 0.16, I 2 = 59.9%, P = 0.000), HoLRP (P = 0.682, SMD = 0.05, 95% CI À0.17 to 0.26, I 2 = 0.0%, P = 0.956), Thulium laser (P = 0.093, SMD = 0.23, 95% CI À0.04 to 0.51, I 2 = 0.0%, P = 0.709), OP (P = 0.220, SMD = 0.19, 95% CI À0.11 to 0.49, I 2 = 76.3%, P = 0.000), and LSP (P = 0.831, SMD = 0.02, 95% CI À0.18 to 0.23, I 2 = 0.0%, P = 0.999) had no effect on EF, whereas patients who underwent HoLEP (P = 0.006, SMD = 0.39, 95% CI 0.11-0.66, I 2 = 60.6%, P = 0.038) and PKEP (P = 0.000, SMD = 0.29, 95% CI 0.19-0.39, I 2 = 0.0%, P = 0.515) had an increased postoperative IIEF-5 score.…”
