We investigated the monopolar and bipolar energy effects on prostate and correlated the results with the type of pathology, thus determining the relationship between tissue damage and the PSA level.
One hundred and twenty four patients underwent TURP and according to the energy source, 2 groups were designed as monopolar (Group 1) and bipolar energy (Group 2). Hemoglobin and free and total PSA were measured preoperatively and 6 hours postoperatively, and differences were calculated. The weight of resected tissue and operation time were also recorded. Two groups were also formed later according to the pathology as chronic prostatitis (CP) and BPH. The findings were analyzed.
There were no statistical differences between the groups in terms of age; prostate volumes; resected tissue; operation times; pre- and postoperative Hb, total-free PSA, IPSS, PVR, and quality of life scores; or postoperative maximum flow rates. Changes in total-free PSA (25.7 and 10.8 ng/dl for PSA; 13.2 and 5.76 ng/dl for free PSA for Groups 1 and 2, respectively) were significantly different between Groups 1 and 2. There was a statistical difference in total PSA between the groups among CP patients (28.18 and 11.73 ng/dl for Groups 1 and 2, respectively). But no statistical difference existed among BPH patients. The change in Hb differed based on pathological results.
Bipolar TURP is less invasive than monopolar TURP on the basis of postoperative PSA levels. In addition, bleeding during TURP is affected not by the kind of energy, but by the pathology.
