Objective: To study the effects of 1470 nm semiconductor laser enucleation of the prostate (SCLEP) and transurethral plasma electrotomy (TUPE) on erectile function and pelvic floor muscle strength in BPH patients.
Methods: We retrospectively analyzed the clinical data on 72 cases of BPH treated in our hospital from July 2017 to July 2019 by TUPE (group A, n = 36) or 1470 nm SCLEP (group B, n = 36). We observed and compared the postoperative penile erectile function, retrograde ejaculation and pelvic floor muscle strength between the two groups of patients.
Results: Compared with group A, group B showed a significantly higher IIEF-5 score (19.43 ± 1.61 vs 21.15 ± 1.32, P < 0.05) and pelvic floor muscle strength (electromyographic ［EMG］ value) during rapid contraction (36.36 ± 1.38 vs 43.53 ± 2.04, P < 0.05), continuous contraction (34.27 ± 1.63 vs 39.46 ± 1.48, P < 0.05) and endurance test (35.24 ± 1.57 vs 38.19 ± 1.67, P < 0.05), but lower incidence rates of ED and retrograde ejaculation.
Conclusions: Compared with TUPE, 1470 nm SCLEP affects less the erectile function and pelvic floor muscle strength of BPH patients.
