Background:
This study aims to investigate the impacts of preoperative maximum detrusor pressure (Pdet.max) on minimally invasive surgery effect on patients with benign prostatic hyperplasia.
Methods:
The clinical data of a total of 156 patients receiving minimally invasive surgery for benign prostatic hyperplasia in Hospital of Nanchang Institute of Medical Sciences from August 2014 to June 2017 were retrospectively reviewed and summarized. The patients were divided into three groups according to different Pdet.max in the urodynamic examination results before the surgery, namely, group A (Pdet.max <50 cmH2O), group B (50≤ Pdet.max <90 cmH2O) and group C (Pdet.max ≥90 cmH2O). The International Prostate Symptom Score (IPSS) and Quality-of-Life score (QOLS) were compared.
Results:
Compared with those in group A, the IPSS and QOLS of the patients in group B and group C at 1 month, 3 months and 12 months after the surgery were decreased notably (all P<0.05). Moreover, the IPSS and QOLS of the patients in group C were obviously lower than those in group B (all P<0.05).
Conclusions:
The results indicated that as the preoperative Pdet.max was increased, the symptoms of the patients receiving minimally invasive surgery for benign prostatic hyperplasia were ameliorated more significantly, and the patients had higher quality of life. The preoperative Pdet.max can judge the treatment effect of minimally invasive surgery on the patients with benign prostatic hyperplasia and help to guide the patients' prognosis. The greater the preoperative Pdet.max is, the better the treatment effect of the patients after the surgery will be, and the higher the quality of life will be.

The Maximum Power Transfer Theorem
The load connected draws the current, and the circuit delivers the power to the load. The alternating current flowing through the load is determined using the rectangular form of voltages, currents, network impedance, and load impedance. The average power delivered to the load is obtained from the product of the square of current and load resistance.
