Summary: | Transurethral resection of the prostate (TURP) is the most common standard surgical procedure used for benign prostatic hyperplasia. Transurethral resection in saline (TURis) is a bipolar electrosurgery system used to prevent TURP (or TUR) syndrome. The bicarbonate Ringer's solution is not generally used as perfusate for TURP. Hence, we compared the efficacy of the bicarbonate Ringer's solution with that of physiological saline as perfusate during TURP. This prospective, multicenter, cooperative study was conducted on 40 adult patients admitted to a medical college hospital. After obtaining informed consent from all the patients, they were divided into two groups (20 patients per group). For patients of one group, bicarbonate Ringer's solution, and for other group, physiological saline was used as perfusate. Compared to the physiological saline, the electrolyte composition of the bicarbonate Ringer's solution was closer to that of plasma. Hence, the group using bicarbonate Ringer's solution as perfusate was exhibited less variation in plasma electrolytes and blood gas data. The primary endpoints were adverse events of grade 1 or higher according to the JCOG postoperative complication criteria ver. 2.0, unintended diseases, or related signs in patients who underwent the protocol therapy. The secondary endpoints were changes in blood pH, bicarbonate ion level, anion gap (AG), base excess (BE), and chloride (C1), which occurred during and after the surgeries. Therefore, bicarbonate Ringer's solution has superior with that of physiological saline as perfusate during TURP which is directly administered into the blood vessels as an infusion solution.Bicarbonate Ringer's solution is directly administered into the blood vessels as an infusion solution.
