123 transurethral resections of the prostate were studied. The operations were randomized to either continuous or intermittent technique. The first 64 operations were performed using an irrigating fluid pressure head of 65 cm (measured from the top of the operating table). In the rest of the operations an 80 cm pressure head was used. In this way four groups were obtained comprising 30 to 31 patients, differing from each other in respect of irrigating technique. Isotonic 5% mannitol solution was used as an irrigating fluid. The irrigating fluid absorptions were calculated from the plasma mannitol levels determined immediately postoperatively. The use of a trocar significantly lessened the average absorbed fluid volume, while there was no significant difference between the groups of high and low irrigating fluid pressure head. The intraoperative bleeding, the decrease in serum sodium, the resection time and resection rate did not differ significantly between the four groups.
对123例经尿道前列腺切除术进行了研究。手术被随机分为连续或间断技术。前64例手术使用65厘米的冲洗液压力头（从手术台顶部测量）。其余手术使用80厘米的压力头。这样就得到了四组，每组有30至31名患者，在冲洗技术方面彼此不同。使用等渗5%甘露醇溶液作为冲洗液。冲洗液吸收量根据术后立即测定的血浆甘露醇水平计算。使用套管针显著减少了平均吸收液体量，而高、低冲洗液压力头组之间没有显著差异。四组之间的术中出血、血清钠降低、切除时间和切除率没有显著差异。
