Objective To analysis the modified Gleason scoring system for predicting the prognosis after radical prostatectomy.Methods A total of 242 patients who received radical prostatectomy from April,2006 to October 2011 were recruited.The patients who lost follow-up or had adjuvant radiation or hormonal therapy or had visceral or bone metastasis were excluded,the remaining 168 patients were evaluated in the present study.The patients' age ranged from 53 to 85 years old (mean age 69 years old).The mean PSA level was 13.31ng/ml (ranging from 4.59 to 36.12 ng/ml).According to the traditional Gleason scoring system,there were 50 patients in Gleason ≤ 6 group,86 patients in Gleason 7 group and 32 patients in Gleason≥8 group.Patients were divided in five groups according to the modified Gleason scoring system.There were 50 patients in Gleason ≤6 group,67 in Gleason 3 + 4 group,19 in Gleason 4 + 3 group,15 in Gleason 8 group and 17 in Gleason 9-10 group.The biochemical-free-survival curve was drawn by Kaplan-Meier method and the multivariate Cox regression models were used to evaluate the clinical and pathological variables for the development of biochemical recurrence.ROC curve analysis was used to determine the predicted value for 5-year BCR of modified and traditional Gleason scoring.Results Significant differences were noted between the modified Gleason scoring groups and traditional Gleason scoring groups in PSA value (P =0.005),pathological stage (P =0.002),extraprostatic extension (P =0.003),seminal vesicle invasion (P =0.004),lymph node involvement (P =0.049) and positive surgical margin (P =0.006).With a median follow-up of 68 months(ranging from 7 to 98 months),5-year BFS rates for men with Gleason grade ≤6,3 + 4,4 + 3,8 and 9-10 tumours on RP pathology were 84.0％ (42/50),76.1％ (51/67),57.9％(11/19),40.0％ (9/15),29.4％ (5/17),respectively.On multivariate analysis,the HR value of Gleason 3 + 4 group and Gleason 4 + 3 group were 1.736 and 2.075 (P ＜ 0.05).The area under the curve in modified and traditional Gleason scoring were 0.698 (95％ CI 0.609-0.788) and 0.674 (95％ CI O.584-0.764),respectively.Conclusions The modified Gleason scoring system is related to the prostate cancer grade and its survival rate.Therefore,it can predict prognosis accurately in patients with prostate cancer.It can potential to reduce overtreatment in patients with Gleason 3 +4 prostate cancer.

Objective To evaluate the clinical feasibility of laparoscopic cool-tip radiofrequency ablation (LCRFA)for renal cell carcinoma. Methods Twelve selected cases of primary renal, ceil carcinoma underwent LCRFA. Of them, 4 cases of left renal carcinomas, 7 cases had right renal carci-nomas and 1 case had bilateral renal carcinomas. The maximum diameter of the tumors was 2.1-8. 5 era. Eleven cases were T, No M0 and the other one was T2 N0 M0. Results The mean operation time was 92±24 min, and the mean blood loss was 50±29 ml. None of the cases need blood transfusion post-operation. No laparoscopic operative complications were observed. Six weeks after operation, complete ablation was achieved in 12 lesions and partial ablation in 1, with a complete ablation rate of 92.3%(12/13). There was no statistic change of Hb. ESR. SCr and GFR after operations (P>0.05). Ten cases underwent CT examination 3 months after the treatment ,9 cases showed complete necrosis of tumor,1 case showed partial necrosis. No recurrence was found. All of the 12 cases remained sur-vived during the follow-up for 1-16 months(median,7.8 months). Conelusions LCRFA for renal cell carcinoma is an accurate and effective intervention with a low incidence of complications, and is more accurate than ultrasound-guided pereutaneous radiofrequency ablation.

Objective To investigate the treatment effect of proximal femoral nail antirotation (PFNA) on unstable femoral intertrochanterie fractures in the elderly. Methods A retrospective stud- y was done on 65 patients with unstable femoral intertrochanteric fractures, who were treated with PFNA from December 2005 to October 2006 and followed up for at least half a year. There were 22 males and 43 females, at age range of 67-97 (mean 78.5 years). All the operations were carried out within a week af- ter fractures. The data of operation time, operative blood loss, complications, bone healing time and hip function scores were recorded for evaluating treatment outcomes. Results All the patients were fol- lowed up for 6-18 months (average 10.5 months). The operation lasted for (29.6±7.5) minutes, with mean blood loss of (150.5±40.2) ml and bone healing time of (9.1±2.2) weeks. All patients ob- tained satisfactory treatment results, except for 3 patients with proximal thigh pain, 2 with pulmonary in- fection occurred and 1 with thrombs of lower limb vein. Harris post trauma hip function score was (88.5 ± 6.3) points. Conclusion PFNA is an effective way for femoral unstable intertrochanteric fractures in the elderly, for it is characterized by short operation time, less blood loss and stable fixation.

Objective To evaluate the safety and short-term efficacy of transrectal ultrasound-guided transperineal cryosurgical ablation(TRUSCSA) for localized prostate cancer. Methods The data of 26 patients who were diagnosed with clinically localized prostate cancer (T_(1a)N_0M_0 - T_(2x)N_0M_0) by biopsy were reviewed. The data of serum prostate-specific antigen (PSA) level, clinical stage and Gleason score were collected. The Gleason score of all cases was ≤7; among them 6 cases were 2 - 4 and 20 cases were 5 - 7. The average pretreatment value of PSA was 11. 9 ng/ml (4. 7 - 19. 2 ng/ml). All the patients were treated with TRUSCSA, with a dual freeze-thaw cycle by using ultrathin 17-gauge cryoneedles. Immediate and delayed morbidities were evaluated. The PSA level was obtained every 3 months for the first 2 years and then every 6 months thereafter, and failure was defined as the inability to reach a nadir of 0. 5 ng/ml or less. All patients were strongly encouraged to undergo routine biopsies despite a stable PSA level. Results The operative time was (102±32)min. The postoperative hospital stay was (6±2)d. After withdrawal of the catheter, 22 cases had good continence) 4 had temporary incontinence for 3 - 7 d. Before operation 9 cases had normal sex life, and among them 5 cases had erectile dysfunction after operation. No one developed urinary retention or urethro-rectal fistula. The follow-up ranged from 6 to 30 months (mean 22). The PSA level at the last follow up visit was less than 0. 5 ng/ml in 23 patients (88%) and 0. 5 ng/ml or more in 3(12%). Postoperative biopsies were taken in 20 cases and the results were negative at the 6th month. Conclusions Transrectal ultrasound-guided percutaneous cryosurgical ablation for clinically localized prostate cancer could be effective and safe. Additional studies with longer follow-up are necessary to determine the sustained efficacy of this procedure.

Objective To evaluate the clinical feasibility of radiofrequency ablation (RFA) for renal cell carcinoma in functional solitary kidney. Methods Five selected cases of primary renal cell carcinoma in a functional solitary kidney were retrospective analyzed. Three cases of left renal cell carcinoma and 2 cases of right renal cell carcinoma were diagnosed by B ultrasound and CT scanning. The maximum diameter of the tumors were 3.0- 6.0 cm. Three cases of which were T1a N0 M0 and the others Were T1bN0M0. All patients were followed up with enhanced-CT and contrast-enhanced ultrasonography. Results The mean time of the operation was 100.0+28.5 min, and the mean blood loss was 95.0±30.5 ml. No patients accepted blood transfusion post-operation. All patients after operation had fever (38.2±0. 7 ℃ ). All the lesions were completely ablated on contrast-enhanced ultrasonography. There was no statistic change of hemoglobin, serum creatinine (SCr), ECT-GFR and creatinine clearance after operation (P>0.05). All of the 5 cases survived. No recurrence were found by enhanced-CT and contrast-enhanced ultrasonography and SCr was retaining in the normal level during follow-ups (median, 11.5 months). Conclusion Radiofrequency ablation for renal cell carcinoma in a functional solitary kidney could be a treatment choice with a relatively low incidence of complications.

Objective To assess the contribution of transrectal realtime tissue elastography (TRTE) on the differential diagnosis of prostatic diseases. Methods A total of 88 prostatic disease patients with 95 lesions proved by pathology from May 2012 to January 2013 in the Afifliated Drum Tower Hospital of Medical College of Nanjing University were included. The elasticity grade and strain ratio were calculated by using TRTE. According to the gold standard of pathological results, the sensitivity, speciifcity, accuracy rate were calculated to evaluate the effectiveness of elasticity grade and strain ratio in distinguishing benign and malignant prostatic diseases;and the receiver operating characteristic (ROC) curves were made respectively. The accuracy of elasticity grade and strain ratio in diagnosing prostatic diseases was also compared using chi-square test. Results Forty-seven benign lesions were found in the 95 prostatic lesions and the other 48 lesions were malignant. The elasticity grades of the 95 prostatic lesions were as follows:GradeⅠ26, GradeⅡ19, GradeⅢ16, GradeⅣ21, and GradeⅤ13. Elasticity grade ≤Ⅱwas considered to be benign, while grade ≥Ⅲwas malignant. The sensitivity, speciifcity, accuracy rate of elasticity grade in diagnosis of prostatic malignant lesions was 79.17%(38/48), 74.47%(35/47) and 76.84%(73/95), respectively. According the ROC curve analysis, the cutoff point of strain ratio was 4.67, and Youden′s index was 0.622. The sensitivity, speciifcity, accuracy rate of strain ratio was 83.33%, 78.72%and 81.05%, respectively. The area under ROC curves of strain ratio was superior to that of elasticity grade. But the diagnosis accuracy of the two approaches was almost the same in statistics (χ2=0.51, P>0.05). Conclusions TRTE is valuable in the differential diagnosis of the prostatic benign and malignant lesions. Both strain ratio and elasticity grade are useful approaches, and have similar diagnostic accuracy.

OBJECTIVETo initially explore the clinical effect of cool-tip radiofrequency ablation combined with enucleation for the giant hamartoma of kidney with narrow base and export-oriented way of growth.
