目的探讨前列腺增生患者电切术前后精液质量的变化。方法选择60例前列腺增生患者电切术前后(已除外术后逆行射精的病例),以及12例正常对照者的精液,并对3组精液主要参数进行比较。结果电切术前后和正常对照者的精子活动力分别为(14.8±2.5)%、(48.5±7.1)%和(61.8±3.3)%;精子存活率分别为(26.2±4.7)%、(74.3±3.4)%和(80.4±2.2)%;精子密度分别为(22.3±4.7)×106/ml、(51.8±16.6)×106/ml和(67.7±13.9)×106/ml。电切术后患者的精子活动力、存活率、密度明显好于术前,差异有显著性意义(P均<0.01);与正常对照组比较,差异无显著性意义(P均>0.05);精子正常形态率与正常对照组及电切术前组比较,差异无显著性意义(P>0.05)。结论成功的电切术可以改善前列腺增生患者的精液质量。 Objective To investigate the changes of semen quality before and after resection in patients with benign prostatic hyperplasia. Methods 60 cases of benign prostatic hyperplasia patients before and after resection of the patient (retrospective ejaculation has been excluded cases), and 12 cases of normal control semen, and the main parameters of the three groups of semen were compared. Results The sperm motility of the patients before and after resection was (14.8 ± 2.5)%, (48.5 ± 7.1)% and (61.8 ± 3.3)%, respectively. The sperm survival rates were (26.2 ± 4.7)% and 74.3 ± 3.4)% and (80.4 ± 2.2)%, respectively. The sperm densities were (22.3 ± 4.7) × 106 / ml, (51.8 ± 16.6) × 106 / ml and (67.7 ± 13.9) × 106 / ml, respectively. The sperm motility, survival rate and density of patients after operation were significantly better than those before operation (all P <0.01). There was no significant difference between the two groups (P> 0.05). There was no significant difference in the normal sperm morphology between normal control group and preoperative resection group (P> 0.05). Conclusion Successful resection of the prostate can improve semen quality in patients with benign prostatic hyperplasia.
