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

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.

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.

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.
