ABSTRACT

Objective:To evaluate the feasibility, safety and efficacy of the magnetic resonance imaging guided focused ultrasound surgery (MRgFUS) in the treatment of localized prostate cancer (PCa).Methods:The data of 5 patients treated by MRgFUS from August 2020 to June 2021 in our institution were retrospectively analyzed. The median age was 73 (58-80) years, with the median PSA of 7.34 (5.19-8.40) ng/ml, and a median prostate volume of 27.96 (21.50-37.91) ml. The median pretreatment international prostate symptom score (IPSS) was 13(0-18). Of the 3 patients with intention of erectile function preservation, the pretreatment international index of erectile function-15 (IIEF-15) score was 12, 23 and 3, respectively. All patients had histopathology-proven PCa of grade group ≤ International Society of Urological Pathology (ISUP) 3, pre-operative PSA level <20 ng/ml, and a clinical stage ≤T 2b. A total of 6 lesions was confirmed by biopsy, with 3 of ISUP grade group 3 and 3 of ISUP grade group 1. All 5 patients underwent MRgFUS which was guided by a real-time magnetic resonance imaging (MRI). PSA, MRI and repeated biopsy were conducted to monitor recurrence. Questionnaires consisted of IPSS, IIEF-15, and the International Consultation on Incontinence-questionnaire-Short Form (ICI-Q-SF) were recorded before and after MRgFUS to evaluate the impact on functional preservation. Results:A total of 5 patients received MRgFUS. In total, 5 of the 6 lesions were treated. 1 lesion unvisible on MRI was not clinically significant and was left untreated. The median time in MRI scanner was 190 (140-355) min, and the median sonication time was 64 (35-148) min with the median sonications of 8 (5-13). The median catheter indwelling time was 1 (1-8) days. No other adverse effects were reported. The PSA level of all 5 patients decreased, with the nadir PSA of 1.196 ng/ml, 4.398 ng/ml, 4.135 ng/ml, 1.562ng/ml and 1.350ng/ml, respectively. 4 of the patients had a PSA decrease over 50%. No PCa lesion was seen on MRI at 3-month follow-up visit. As for functional preservation, the post-MRgFUS IPSS declined compared with the baseline score, and the IPSS of last follow-up was 5(0-14). Of the 3 patients with intention to preserve the erectile function, the erectile function score of IIEF-15 were 12, 30 and 9 three months after the treatment, respectively. No incontinence occurred postoperatively.Conclusions:MRgFUS is a feasible and safe way for the treatment of low- to intermediate-risk localized PCa, with satisfactory performance on functional preservation and low incidence of complications. The oncological outcomes still need to be establised with longer follow-up time and larger sample studies.

ABSTRACT

This study prospectively collected the clinical data of patients who received sacral neuromodulation(SNM)variable-frequency stimulation (VFS) mode from June 2020 to December 2020, in order to explore the efficacy and safety of VFS mode in the treatment of refractory lower urinary tract dysfunction. The inclusion criteria were as follows: ①SNM was implanted; ②age ≥18 years old; ③The traditional constant-frequency stimulation (CFS) mode has poor therapeutic effect, and can not be improved after repeated adjustment of stimulation parameters; ④Patients with overactive bladder (OAB) symptoms, who fail to respond to conservative treatment or are intolerant to conservative treatment; ⑤The drugs that affect the lower urinary tract symptoms and pelvic function should not be increased or decreased during the trial; ⑥provision of informed consent. A total of six patients meeting the criteria were included in the study, with three males and three females. The age ranged from 47 to 74 years, with an average age of 55 years. Among those patients, three cases were diagnosed of OAB, two cases were diagnosed of interstitial cystitis, and one case was diagnosed of neurogenic bladder. All patients had received CFS-SNM for an average of 20.6 months before upgrading to VFS mode, and suffered from severe frequency of urination at the same time. Compared with the severity of symptoms during the baseline period and the CFS period, a trend of improvement was found among four patients during the VFS period. The severity of symptoms was mainly based on the average daily urination frequency and OAB-Q score. For the two patients with interstitial cystitis, OAB symptoms worsened during the VFS period, while the VAS score did not change significantly. In general, VFS-SNM is not inferior to CFS-SNM in improving the symptoms of frequent micturition. For patients with interstitial cystitis, multiple sets of VFS parameters can be tried under the premise of satisfactory pain management.

ABSTRACT

The development of urodynamics in China is the epitome of the country's reform and opening up, economic development, and technological progress. With the continuous popularization of urodynamic measurements and the emergence of new technologies, it is necessary to further establish and promote urodynamic quality control standards and to develop talents-nurturing and training systems. Urodynamic quality control is a complex systematic project and an original research. Quality control depends on typical value ranges, typical signal pattern and technical standard. Quality control should be performed in the real-time measurement and retrospective data analysis. The urodynamic training will combine the professional course with popular one. Quality of Urodynamics will be improved continuously.

ABSTRACT

Objective:To evaluate the cancer detection rate in patients with multiparametric magnetic resonance imaging (mpMRI) PI-RADS 1-2 prior to initial biopsy, and analyze the risk factors of prostate cancer.Methods:A total of 196 patients undergoing initial prostate biopsy between July 2011 and June 2018 were retrospectively analyzed. According to ESUR PI-RADS system, the patients’ PI-RADS score was 1 and 2, with the mean age of 66.6±9.0 years, and the median PSA 7.44 ng/ml. Twenty-eight patients were enrolled with PSA<4 ng/ml but with abnormal directeral rectun examination. The rest 168 patients were enrolled with elevated PSA. According to the Epstein prostate risk classification criteria, clinically insignificant prostate cancer was defined as: PSA density ≤0.15 ng/ml 2, Gleason score≤6, less than 3 positive needles, <50% puncture length. If any of the above is not met, the diagnosis should be clinically significant prostate cancer(CsPCa). T test or Mann-Whitney U test were used for comparison between groups. Risk factors for diagnosis of prostate cancer and CsPCa were analyzed by chi square test(or Fisher’s exact probability method) and multivariate logistic regression analysis. Results:There were 42(21.4%) patients diagnosed with prostate cancer, 30(15.3%)patients were CsPCa. The negative predictive value of mpMRI was 78.6%(154/196)for prostate cancer overall, and 84.7%(166/196)for CsPCa. Patients with higher age and PSA density were associated with higher possibility of prostate cancer. Higher age, PSA level, PSA density, and lower PSA ratio were associated with higher possibility of CsPCa. Multivariate logistic regression analysis showed that PSA density>0.15 ng/ml 2( OR=2.94, 95% CI 1.45-5.95) was independent risk factor of prostate cancer.Ages over 70 years( OR=2.49, 95% CI 1.22-5.07), PSA ratio<0.2( OR=3.70, 95% CI 1.25-11.23), PSA density>0.15 ng/ml 2( OR=5.77, 95% CI 1.96-16.96) were independent risk factors of CsPCa ( P<0.05). Conclusions:The detection rate of prostate cancer was 21.4% in patients with elevated PSA or abnormal digital prostate examination but with PI-RADS score of 1-2. Higher age and PSA density were associated with higher risk of prostate cancer. The detection rate of CsPCa was 15.3%. Ages over 70 years, PSA ratio<0.2, PSA density>0.15 ng/ml 2 were independent risk factors of CsPCa.

ABSTRACT

Objective:To investigate the detection rate and the characteristics of detected prostate cancer foci on multi-parametric MRI (mp-MRI) and to evaluate the potential influence factors.Methods:A total of 66 patients undergoing radical prostatectomy (RP) from August 2017 to July 2019 in Beijing Hospital were retrospectively studied. The median age was 67(56-80)years, with the median preoperative PSA level of 8.73 (1.22-72.46)ng/ml, and median prostate volume of 35.9(16.8-131.8) ml. All patients underwent mp-MRI before surgery and the whole mount section of RP specimens was prepared. Two radiologists reviewed all the foci independently and then matched each foci with an urological pathologist. The primary outcome was the detection rate of prostate cancer. The potential influence factors were also investigated.Results:Of all 66 patients, a total of 62(93.9%) patients were diagnosed with prostate cancer on a preoperative mp-MRI. On whole mount section, 109 prostate cancer foci were detected, of which 77 foci were correctly diagnosed on mp-MRI, with the overall sensitivity of 70.6%. For all the foci detected, 53(48.6%) were grade group 1 disease of International Society of Urological pathology (ISUP), 31(27.5%) were ISUP grade group 2 disease, 19(17.4%) were ISUP grade group 3 disease, and 6(5.5%) were ≥ISUP grade group 4 disease. Mp-MRI detected 62/67(92.5%) lesions with tumor diameter ≥1 cm, 49/56(87.5%) lesions with tumor Gleason score ≥7, and 59/66(89.4%) index lesions. The tumor diameter( OR=3.183, 95% CI 1.580-6.411, P=0.001)and index lesion status( OR=4.042, 95% CI 1.127-14.503, P=0.032)were independently associated with the detection of prostate cancer foci on mp-MRI. Conclusions:mp-MRI is an effective technique for prostate cancer detection. Sensitivity increased with increased tumor size and index lesion status. The tumor diameter and index lesion status were independently associated with the detection of prostate cancer foci on mp-MRI.

ABSTRACT

Objective:To establish a nomogram model for predicting positive resection margins after prostate cancer surgery, and to perform the corresponding verification, in order to predict the risk of positive resection margins after surgery.Methods:A total of 2 215 prostate cancer patients from The First Affiliated Hospital of Naval Medical University, Hospital, Peking University First Hospital, Peking University Third Hospital, Peking University, and First Affiliated Hospital of Xi′an Jiaotong University were included in the PC-follow database from 2015 to 2018, and a simple random sampling method was used. They were divided into 1 770 patients in the modeling group and 445 patients in the verification group. In the modeling group, the age (<60 years, 60 to 70 years, >70 years), PSA (<4 ng/ml, 4-10 ng/ml, 11-20 ng/ml, >20 ng/ml), pelvic MRI (negative, suspicious, positive), clinical stage of the tumor (T 1-T 2, ≥T 3), percentage of positive needles (≤33%, 34%-66%, >66%), Gleason score of biopsy pathology (≤6 points, 7 points, ≥8 points). Univariate and multivariate logistic analysis were performed to screen meaningful indicators to construct a nomogram model. The model was used for validation in the validation group. Results:The results of multivariate analysis showed that preoperative PSA level ( OR=2.046, 95% CI 1.022 to 4.251, P=0.009), percentage of puncture positive needles ( OR=1.502, 95% CI 1.136 to 1.978, P=0.002), Gleason score of puncture pathology ( OR=1.568, 95% CI 1.063 to 2.313, P=0.028), pelvic MRI were correlated ( OR=1.525, 95% CI 1.160 to 2.005, P=0.033). Establish a nomogram model for independent predictors of positive margin of prostate cancer. The area under the receiver operating characteristic (ROC) curve of the validation group is 0.776. The area under the ROC curve of the preoperative PSA level, percentage of puncture positive needles, puncture pathology Gleason score, pelvic MRI, postoperative pathology Gleason score were 0.554, 0.615, 0.556, 0.522, and 0.560, respectively. The difference between the nomogram model and other indicators was statistically significant ( P<0.05). Conclusions:The constructed nomogram model has higher diagnostic value than the preoperative PSA level, percentage of puncture positive needles, Gleason score of puncturing pathology, pelvic MRI, and postoperative pathological Gleason score in predicting positive margin.

ABSTRACT

Urinary continence is an important branch of the urology and one of the most complex fields. The scientific research and clinical works in the field of urinary continence in China started late and from a low starting point. Over the past 40 years, with the joint efforts of our colleagues in the field of urology, the field of urinary continence in China has developed rapidly in the fields of urodynamics, urinary incontinence, overactive bladder, neurourology, functional urology, pelvic floor dysfunction, etc., and a significant progress has been made; but there are still some gaps compared with the international level. The Chinese Journal of Urology has been following the development of urinary continence in China. On the occasion of the 40th anniversary of the publication of the Journal, we made a review based on the retrieved papers published in this journal, in order to congratulate the Chinese Journal of Urology on its 40th birthday, and to urge and encourage the urinary continence workers to make more efforts, to promote the Chinese cause of urinary continence to a higher level.

ABSTRACT

Objective:To investigate the effect of maximal androgen blockade(MAB)therapy on serum calcium, phosphorus and other metabolic indices in elderly patients with prostate cancer.Methods:Clinicopathological data of prostate cancer patients treated with MAB in our department from January 2010 to December 2018 were retrospectively analyzed.All patients underwent prostate biopsy for definitive diagnosis.Detailed data on patient's age, body mass index(BMI), previous medical history, treatment plan and peripheral blood indicators before and after endocrine treatment, such as blood calcium, phosphorus, hemoglobin, fasting blood glucose, triglycerides and cholesterol, were collected.Results:Patients had a mean age of(75.5±5.8)years and a mean BMI of(24.6±3.2)kg/m 2.Blood calcium levels exhibited a downward trend after MAB treatment compared pre-treatment[(2.12±0.44)mmol/L vs.(2.17±0.31)mmol/L, t=0.82, P=0.42], but had no significant difference.Serum phosphorus concentrations were higher and the calcium-phosphorus ratio was lower after MAB treatment than before treatment[(1.02±0.26)mmol/L vs.(1.17±0.34)mmol/L, 2.10±0.28 vs.1.88±0.60, t=-4.12 and 3.56, P<0.01]. After MAB treatment, blood fasting glucose[(6.50±1.55)mmol/L vs.(5.34±1.04)mmol/L, t=-7.82, P<0.01], triglycerides[(1.66±1.32)mmol/L vs.(1.22±0.59)mmol/L, t=-3.38, P<0.01]and cholesterol[(4.70±1.08)mmol/L vs.(4.16±0.90)mmol/L, t=-4.72, P<0.01]were elevated, while hemoglobin concentrations[(122.11±20.43)g/L vs.(130.78±23.98)g/L, t=3.98, P<0.01]were decreased compared with pre-treatment levels. Conclusions:MAB therapy can cause varying degrees of metabolic abnormalities in calcium and phosphorus metabolism, hemoglobin concentrations, blood glucose and lipid levels in elderly prostate cancer patients.The above indicators should be closely monitored during treatment, and treatment-related complications should be proactively prevented.

ABSTRACT

Objective:To investigate the risk factors for Gleason score upgrading after radical prostatectomy in clinical low-risk prostate cancer patients aged≥65 years.Methods:A total of 485 clinical low-risk prostate cancer patients aged≥65 years at five centers of the national multi-center PC-follow database from January 2015 to March 2019 were retrospectively analyzed.Data including age at diagnosis, prostate-specific antigen(PSA), MRI prostate imaging, puncture Gleason score, operation method, puncture method, positive incision margin and capsule penetration were collected.Differences in Gleason scores before and after operation were compared, and the risk factors for Gleason score upgrading after radical resection were evaluated by univariate and multivariate Logistic regression analysis.Results:Of 485 patients with a puncture Gleason score of 3+ 3=6, 261(53.8%)cases had postoperative pathological upgrading, in whom 228(87.4%)cases had Gleason score upgrading of 7, 22(8.4%)had Gleason score upgrading of 8, and 11(4.2%)had Gleason score upgrading of 9 or more.The rate of Gleason score upgrading was elevated with increased preoperative PSA levels, positive pelvic MRI, and higher positive rates of puncture biopsy.The incidences of postoperative capsule penetration(27.2% vs.12.5%, P<0.001)and positive incision margin(25.2% vs.17.4%, P=0.036)had statistically significant differences between the pathologically upgraded group and the pathologically non-upgraded group.Multivariate analysis showed that preoperative PSA level, percentage of positive puncture biopsies, biopsy Gleason score and pelvic MRI were independent predictors of prostate cancer. Conclusions:For clinical low-risk prostate cancer patients aged≥65 years with high risk factors for Gleason score upgrading, repeated biopsies should be carried out when necessary and the treatment plan should be adjusted accordingly.

ABSTRACT

Objective To evaluate the value of kidney-sparing surgery in the treatment of upper urinary tract urothelial tumors by retrospectively analyzing and comparing the clinical data of elderly patients with upper urinary tract urothelial tumors between patients undergoing kidney-sparing surgery and nephroureterectomy in our hospital during the same period.Methods Thirty elderly patients with upper urinary tract urothelial tumors were treated with kidney-sparing surgery(ureteroscopy,segmental ureteral resection)and followed up from April 2004 to July 2017.One hundred and fortynine patients who underwent nephroureterectomy during the same period were selected as the control group.The survival rate and local recurrence rate were compared between the two groups.Results In the kidney-sparing group,23 cases were pathologically diagnosed as tumors,3 cases as inflammatory polyps and 4 cases without pathological findings.There were no statistically significant differences between kidney-sparing surgery and nephroureterectomy in bladder recurrence[4 cases(13.3%)vs.24 cases(16.1%),x2 =0.011,P =0.915],pelvic orthotopic recurrence [3 cases (10.0%) vs.6 cases (4.0%),x2 =0.825,P=0.364],cancer-specific death rate[2 cases(6.7%)vs.16 cases(10.7%),x2=0.118,P=0.731]and overall survival rate[4 cases(13.3%)vs.22 cases(14.8%),x2 =0.410,P =0.550].There were no significant differences between kidney-sparing surgery versus nephroureterectomy among postoperative 1-year,5-year and 10-year in the overall survival rates (100.0 %vs.95.1%、85.9 % vs.84.1%、80.5 % vs.60.8 %,P =0.156),tumor-specific survival rates (100.0 % vs.95.1%,85.7 % vs.87.6 %,85.7 % vs.76.8 %,P =0.380) and progression-free survival rates(100.0%vs.100.0%,90.9%vs.96.0%,90.9% vs.79.7%,P =0.680).Conclusions Elderly patients have poor physical conditions and poor tolerance to radical surgery with a significant damage on postoperative renal function.Kidney-sparing surgery(ureteroscopy,segmental ureteral resection) as the treatment of upper urinary tract tumors can minimize the risk of surgery and optimize the quality of life.The individual assessment based on individual conditions,postoperative complications,and the recovery of renal function should be conducted and the operation with the greatest benefit should be adopted.

Objective To translate the International Consultation on Incontinence Modular Questionnaire for Male Lower Urinary Tract Symptoms (ICIQ-MLUTS) and ICIQ-MLUTS long form (ICIQ-MLUTS LF) into Chinese and assess their metric properties and applicability.Methods After obtaining permission from the International Consultation on Incontinence Questionnaire (ICIQ),original ICIQ-MLUTS and ICIQ-MLUTS LF were translated into Chinese according to ICIQ validation protocol and cultural adaptation guideline.During November 2017 to August 2018,Chinese version of ICIQ-MLUTS and ICIQ-MLUTS LF were tested by administering them in 6 and 12 hospitals in China respectively.To validate the translated questionnaires,the following tests were undertaken.The content validity was determined by indepth interviews with participants and experts.The correlation coefficients of ICIQ-MLUTS and ICIQ-MLUTS LF with International Prostate Symptom Score (IPSS) were assessed to validate criterion validity.Cronbach's alpha test was used to explore internal consistency.And the test-retest reliability was evaluated by calculation of intraclass correlation coefficient.Results In total,Chinese ICIQ-MLUTS and ICIQ-MLUTS LF were administrated to 135 and 230 male patients with lower urinary tract symptoms respectively.Both questionnaires had good content validity and good criterion validity with IPSS (Pearson correlation 0.846 and 0.833 for ICIQ-MLUTS and ICIQ-MLUTS LF respectively,both P < 0.001).The Cronbach's alpha coefficient was 0.797 for ICIQ-MLUTS,and 0.853 for ICIQ-MLUTS LF.Intraclass correlation coefficient was 0.986 and 0.985 respectively (both P < 0.001),showing good test-retest reliability.Conclusions The Chinese version of ICIQ-MLUTS and ICIQ-MLUTS LF had good validity and reliability,which can be used to assess Chinese male patients with lower urinary tract symptoms.

ABSTRACT

Objective To investigate the effects of radical prostatectomy on the overall survival (OS)and tumor-specific survival in prostate cancer(PCa)patients aged 75 years and older.Methods Clinical data of patients aged 75 and older with localized PCa from Surveillance,Epidemiology,and End Results(SEER)Database from 2004 to 2016 were retrospectively analyzed.There were 17 899 cases of PCa undergoing radical prostatectomy and 3 648 cases of PCa without surgery in this study.The OS and prostate cancer-specific survival(PSS)were compared between the surgery group and the nonsurgery group.Results For 75-79-year-old patients with high-risk localized PCa,the OS and PSS in the surgery group were better than in the non-surgery group (OR =1.49,95 % CI:1.22 ~ 1.82,P < 0.01;OR=1.43,95%CI:1.09~2.04,P<0.05).For patients aged 75-79 years with low-risk PCa and patients aged 80 years and older with low-,middle-,or high-risk PCa,the OS was worse in the surgery group than in the non-surgery group(OR =0.54,95%CI:0.38~0.76,P<0.01;OR =0.47,95%CI:0.34~0.66,P<0.01;OR =0.58,95%CI:0.44~0.78,P<0.01;OR =0.59,95%CI:0.51 ~0.68,P<0.01).For patients aged 75-79 years with low-or medium-risk PCa and patients aged 80 years and older with medium-risk PCa,there was no statistical difference in PSS between the surgery and non-surgery groups(P>0.05).Conclusions Age limits for prostatectomy should be extended as a result of increasing average life expectancy.Patients aged 75-79 years with high-risk PCa can be considered for surgical treatment,while it should not be recommended for patients aged 75-79 years with low-or medium-risk localized PCa or aged more than 80 years.Many factors should be considered in making treatment decisions for prostate cancer.

ABSTRACT

Objective To investigate the relationship between preoperative urodynamic parameters and the improvement of overactive bladder (OAB)symptoms after GreenLight laser vaporization,and to explore prognostic factors for improvement of OAB symptoms in the elderly.Methods A retrospective study was conducted in 100 benign prostatic hyperplasia (BPH)patients undergoing GreenLight laser vaporization at the Department of Urology of Beijing Hospital from July 2015 to March 2017.All patients completed a preoperative urodynamic examination and received GreenLight laser vaporization.Clinical data including age,prostate-specific antigen (PSA),prostate volume,international prognostic scoring system(IPSS),overactive bladder symptom score (OABSS),quality of life(QOL)and urodynamic parameters were collected.The related factors for improvement of OAB symptoms after GreenLight laser vaporization were analyzed by a binary Logistic regression analysis.Results All patients underwent surgery successfully and completed a 12-month follow-up.Both urinary storage and voiding symptoms improved at 3 and 12 months after GreenLight laser vaporization(P<0.05).The scores of IPSS,IPSS storage (IPSS-S),IPSS voiding (IPSS-V),OABSS and QOL and nighttime voiding frequency decreased and urinary storage and voiding symptoms improved at 3 and 12 months after GreenLight laser vaporization,compared with pre-surgery data(P<0.05).The success rates of storage symptom improvement at 3 and 12 months after GreenLight laser vaporization were 62.0 % (62/100) and 68.0 % (68/100) evaluated by IPSS-S and 68.0 % (68/100) and 75.0% (75/100)by OABSS,respectively.Multiple Logistic regression analysis showed that age,detrusor contractility,residual urine volume and nighttime voiding frequency were independent influencing factors for prognosis(OR =35.714,0.352,0.110 and 0.040,P =0.000,0.027,0.018 and 0.002).Conclusions GreenLight laser vaporization is an effective method in treating BPH with OAB.Age is an independent unfavorable factor and the residual urine volume,nighttime voiding frequency and detrusor contraction are independent influencing factors for prognosis.Enough attention should be paid to these related parameters before surgery.

ABSTRACT

Objective To analyze the associated factors of positive surgical margin after radical prostatectomy.Methods A retrospective analysis was conducted on 320 patients who underwent radical prostatectomy from June 2007 to June 2017,whose age was 45-80 years(mean 67.9) and PSA was 0.05-123.19 ng/ml (mean 14.4ng/ml).The patients were divided into groups by age,PSA,PI-RADS score,clinical stage,biopsy Gleason score and operation approach.Chi-square test was used for single factor analysis and binary logistic regression analysis for multivariate analysis to evaluate the correlation between clinical and pathological data and positive cutting edge.Result Among the total 320 patients,there were 94 (29.4%) patients had positive surgical margin after radical prostatectomy.There were 26 (21.0%) positive surgical margin located at ventral sites,18(14.5%) located at dorsal sites,21 (16.9%) located at base,and 59(47.6%) located at tip.The positive rate of surgical margin was different in different positive areas of MRI (P <0.01),among which the MRI showed cancer located in the tip of prostate had the highest positive rate (47.6%) of surgical margin after prostatectomy.Univariate risk factor analysis was performed which showed that PSA(P =0.023),positive needle percentage (P =0.001),biopsy pathologic Gleason score(P =0.029),PI-RADS score (P =0.022) and prostate cancer risk score (P =0.006) had significant correlation with positive surgical margin.The age (P =0.257),clinical stage (P =0.161) and operation approch (P =0.260) had no significant correlation.Then multivariate analysis showed that PI-RADS score (P =0.023) and positive needle percentage (P =0.047) could be used as independent predictors of positive surgical margin.Conclusions PI-RADS score and percentage of positive biopsy needles were independent risk factors for positive surgical margin after prostatectomy.There was highest positive rate of surgical margin when MRI showed cancer located at the tip of prostate.
