目的

探讨手术切除前列腺质量与术前超声测量前列腺质量的相关性及临床应用价值。

方法

选取2021年8月至2024年7月芜湖市第一人民医院收治的128例前列腺增生的患者作为研究对象，将入组患者随机分为经尿道等离子前列腺剜除术（PKEP）组64例与经尿道等离子前列腺切除术（PKRP）组64例，分别行PKEP与PKRP手术，比较两组的手术切除率及对手术切除前列腺质量与术前超声测量前列腺质量进行相关性分析。

结果

两组手术切除前列腺质量及术前超声测量前列腺质量数据均呈正态分布。PKEP手术前列腺切除率为（61.13%±4.38%），PKRP手术前列腺切除率为（54.52%±8.32%），PKEP的手术前列腺切除率明显高于PKRP的手术前列腺切除率（P<0.05）。当术前超声测量前列腺质量>60 g时，PKEP组的手术前列腺切除率明显高于PKRP组的手术前列腺切除率（P<0.05）；当术前超声测量前列腺质量≤60 g时，PKEP组与PKRP组手术前列腺切除率比较差异无统计学意义（P>0.05）。PKEP组与PKRP组手术切除前列腺质量与经术前超声测量前列腺质量均呈线性相关（P<0.05）。PKEP组手术切除前列腺质量及术前超声测量前列腺质量呈一元线性回归，回归方程：Y=1.570X+4.137。

结论

PKEP手术在大体积前列腺中前列腺切除率较高，优势明显。在PKEP组与PKRP组手术切除前列腺质量与术前超声测量前列腺质量均呈线性相关，应用PKEP的手术切除前列腺质量与术前超声测量前列腺质量得出的回归方程，可预测前列腺腔内手术切除的彻底性及术后远期排尿效果。

Objective

To explore the correlation between the mass of surgically resected prostate and preoperative ultrasound-measured prostate mass and its clinical application value.

Methods

128 patients with benign prostatic hyperplasia admitted to the First People’s Hospital of Wuhu from August 2021 to July 2024 were selected as the research subjects, and the patients were divided into two groups, with 64 patients who underwent transurethral plasmakinetic enucleation of the prostate (PKEP) and 64 patients who underwent the transurethral plasmakinetic resection of the prostate (PKRP) randomly. The surgical resection rates of the two groups were compared, and the correlation between the mass of the surgically resected prostate and the preoperative prostate mass measured by ultrasound was analyzed.

Results

The mass of the surgically removed prostate and the mass of the prostate measured by ultrasound before surgery were normally distributed in both groups. The surgical resection rate of PKEP was (61.13%±4.38%), and the surgical resection rate of PKRP was (54.52%±8.32%). The surgical resection rate of PKEP was higher than that of PKRP (P<0.05). When the preoperative prostate mass measured by ultrasound was greater than 60 g, the rate of resection for the prostate of the PKEP group was significantly higher than that of the PKRP group (P<0.05). When the preoperative prostate mass measured by ultrasound was less than 60 g, there was no significant difference in the prostate resection rate between the PKEP group and the PKRP group (P>0.05). The mass of the surgically resected prostate in the PKEP and PKRP groups were linearly correlated with the preoperative mass of the prostate measured by ultrasound. The mass of the surgically resected prostate and the preoperative mass of the prostate measured by ultrasound in the PKEP group showed a linear regression, and the regression equation was Y=1.570X+4.137.

Conclusions

PKEP has a higher rate of resection for prostate in the enucleation of large-volume prostates, with obvious advantages. There is a linear correlation between the mass of the surgically resected prostate and the preoperative mass of the prostate measured by ultrasound in both the PKEP group and the PKRP group. The regression equation derived from the mass of the surgically resected prostate and the ultrasound-measured prostate mass can predict the thoroughness of endoscopic surgical resection of the prostate and the long-term postoperative urinary effect.
