[Transurethral prostatectomy with the bipolar plasma kinetic technique for benign prostate hyperplasia: a report of 297 cases].

OBJECTIVE: To evaluate the effect and safety of transurethral prostatectomy with the bipolar plasma kinetic technique (PKRP) in the treatment of benign prostate hyperplasia(BPH). METHODS: Two hundred and ninty-seven BPH patients underwent transurethral prostatectomy with the bipolar plasma kinetic technique. The preoperative estimated weight of the prostate ranged from 35 g to 102 g, averaging 52 g. RESULTS: The operation lasted 40 approximately 65 min, averaging 51 min. The resected tissues weighed 40 approximately 80 g, averaging 46 g. During the operation no transurethral resection (TUR) syndrome occurred. The catheter was removed 4 approximately 5 days after the operation, all with fluent urination. The patients were followed up for 2 approximately 33 months. IPSS decreased from average 31.5 preoperatively to average 6.8 postoperatively (P < 0.001). Average maximum flow-rate (Q(max)) decreased from 6.3 ml/s preoperatively to 18.6 ml/ s postoperatively (P < 0.001). Preoperative average residual urine was 97 ml and reduced to average 9 ml after the operation. Temporary incontinence occurred in 4 cases, perioperative hemorrhage in 2, and urethral stricture in 1. CONCLUSION: Transurethral prostatectomy with the bipolar plasma kinetic technique is a safe and effective means for the treatment of BPH.

[The combined therapy of intervention, operation and biology in patients with middle-advanced renal cell carcinoma].

OBJECTIVE: To observe the effect of the combined therapy of intervention, operation and biology in patients with middle-advanced renal cell carcinoma. METHODS: Combined therapy was used in 52 cases as combined care groups and the single operational therapy was used in 50 cases as control group. Compare their resection rates, surgical risks and 3, 5 years survival rates. RESULTS: In the combined care group, the excision rate was 100%, the average amount of blood transfusion during the operation was 280 ml, the average operation time was 100 minutes, and the 3, 5 years survival rates were 73% and 50%; While in the control group, the results were 90%, 396 ml, 130 minutes, 55% and 27% respectively. There were significant differences between 2 groups (P < 0.05). CONCLUSION: Combined therapy could elevate resection rates and 3, 5 years survival rates and decrease surgical risks.
