Objective:To investigate the effect of local anesthesia in patients with a PI-RADS score of 5 and ECOG score ≥2 for prostate puncture.Methods:Retrospective analysis of case data of 33 patients admitted to the Subei People's Hospital for prostate puncture from April 2020 to April 2022. Age (82.5±3.6) years. There were 18 cases with hypertensive disease, 8 cases with diabetes mellitus, and 6 cases with both diabetes mellitus and hypertensive disease. Body mass index (25.2±3.5) kg/m 2. prostate-specific antigen (PSA)(131.5±69.7) ng/ml. prostate volume (38.5±21.4) ml. all patients had a PI-RADS score of 5 on multiparametric magnetic resonance (mpMRI) and an Eastern Cooperative Oncology Group (ECOG) score ≥2. All 33 cases in this group underwent trans-perineal targeted prostate puncture using local anesthesia at the tip of the prostate. The visual analog score (VAS) and visual numeric score (VNS) were applied by the same surgeon to assess the patient's pain level and satisfaction at the time of puncture (VAS-1 and VNS-1) and 30 min after puncture (VAS-2 and VNS-2), and to record the duration of the procedure and the occurrence of postoperative complications. Results:In this group of 33 cases, the VAS-1 score was (1.9±0.3) and the VAS-2 score was (0.1±0.2); the VNS-1 score was (2.9±0.2) and the VNS-2 score was (3.9±0.1). Postoperative pathological results indicated that one of the 33 patients had a negative puncture result (pathology report indicating interstitial inflammation), while the rest of the patients had a positive puncture pathology report (puncture pathology report indicating prostate cancer), with a positive rate of 97%. One case of postoperative carnal haematuria occurred, which gradually improved after the patient was advised to drink water and take alpha-blockers. No perineal hematoma occurred, and all patients did not suffer complications such as urinary tract infection, urinary retention, azoospermia, vagal reaction, and infectious shock.Conclusion:In patients with a PI-RADS score of 5 and ECOG score ≥2, the use of single-hole local anesthesia for performing trans-perineal targeted puncture biopsy has the advantages of good paroxysmal pain and high safety.

Objective:To explore the feasibility and safety of the clinical application of the diagnosis and treatment mode combining rapid frozen pathological examination of prostate biopsy tissue with radical prostatectomy.Methods:Suspected prostate cancer patients with PSA>10 ng/ml and PI-RADS score ≥4 in, Northern Jiangsu People's Hospital from April to September 2021 were collected. The included patients underwent mpMRI/TRUS image fusion-guided transperineal prostate targeted biopsy with 16G biopsy needle, 2-3 needles for biopsy, and rapid frozen pathological examination. Robot-assisted laparoscopic radical prostatectomy (RALP) was performed immediately for patients with prostate cancer with rapid freezing pathology. For undiagnosed prostate cancer, 18G biopsy needle for prostate targeted + systematic biopsy were used, 18-22 needles for systematic biopsy, and routine pathological examination. The baseline data, frozen pathological results, perioperative conditions, pathological results and follow-up data of all patients were collected.Results:Eleven patients were included in the study, the mean age of the patients was 69.9(66-73) years, the mean BMI was 22.8(19-26) kg/m 2, the mean PSA was 23.2(14.25-32.00), the mean prostate volume was 45(32-52) ml, mean PSAD 0.54(0.33-0.75). PI-RADS score was 4 in 3 cases and 5 in 8 cases; digital rectal examination was positive in 5 cases. All 11 cases underwent rapid freezing and the pathological results showed that: 9 cases were prostate adenocarcinoma, and RALP was performed immediately. The operation time was 111.5(96-126) min, the intraoperative blood loss was 78.9(55-105) ml, and the postoperative extubation time was 4.3(3.5-5.0) days, postoperative hospital stay 5.8(5.0-6.5) days. Postoperative pathology showed that Gleason score 3+ 4=7 in 1 case, 4+ 3=7 in 3 cases, 8 points in 4 cases, and 10 points in 1 case; 3 cases had positive resection margins, and 1 case had seminal vesicle invasion, the average number of dissected lymph nodes was 10.9 (8.5-14.0), and there was no tumor metastasis. Pathological T staging included 2 cases of T 2b stage, 5 cases of T 2c stage, 1 case of T 3a stage, and 1 case of T 3b stage. Two patients were undiagnosed by rapid freezing pathology, of which one was prostate adenocarcinoma with a Gleason score of 4+ 3=7, and then received RALP; the other one was prostate inflammation. 11 patients were followed up; the postoperative follow-up time was 3-7 months, with an average of 5.2 months. Among the 10 patients who underwent RALP, 8 patients recovered urinary continence 2 weeks after surgery, and all recovered within 2 months after surgery. Three patients with positive surgical margins were given regular androgen deprivation therapy in the second week after surgery. PSA did not drop below 0.1 ng/ml in patients with positive margins and seminal vesicle invasion 3 months after surgery. No complications of Clavien grade Ⅰ or higher occurred after operation and during follow-up. Conclusions:For patients with high suspicion of prostate cancer, rapid frozen pathological examination of prostate biopsy tissue is performed. RALP is performed immediately for patients with prostate cancer. The results show that this diagnosis and treatment model could be safe and feasible.

The present study retrospectively analyzed the clinical data of 137 patients who underwent prostate in North Jiangsu People's Hospital from June 2020 to May 2021. All patients underwent peripheral prostatic nerve block anesthesia (PPNB). The observation group received 1% ropivacaine 32 ml local, and the control group received the same dose of lidocaine. There was no significant difference in general data before puncture between the two groups ( P>0.05). All 137 cases were performed by the same surgeon. The number of puncture needles in the observation group and the control group was (20.2±2.8) and (20.2±2.9), respectively, and the difference was not statistically significant ( P>0.05). The visual analogue scores (VAS-1) of pain during puncture in the observation group and the control group were (2.62±0.74) and (2.48±0.79) points, respectively. The visual numeric score (VNS-1) was (3.03±0.88) points and (3.15±0.80) points, respectively, and there was no significant difference ( P>0.05). 30 min after puncture, VAS-2 was (0.48±0.53) points and (0.30±0.47) points, VNS-2 was (3.31±0.48) points and (3.55±0.71) points, respectively.The differences were statistically significant ( P<0.05). There was no significant difference in overall complication rate between the two groups ( P=0.661).

Objective:To analyze the risk of missed diagnosis in patients with PI-RADS score>3 and negative prostate initial biopsy and to explore its risk factors.Methods:The clinical data of 268 patients with negative prostate biopsy in Northern Jiangsu People's Hospital from May 2013 to December 2018 were retrospectively analyzed. The patients were divided into observation group (PI-RADS score>3) and control group (PI-RADS score≤ 3) according to different PI-RADS scores. There were insignificant differences in age [(67.4(60.0, 74.0)years and 65.6(66.5, 72.0)years], prostate volume of initial biopsy [62.4(40.0, 72.0)ml and 60.8(38.0, 77.0)ml], biopsy cores [ 20.6(18.0, 22.0)cores and 20.4(18.0, 22.0)cores] between the observation group (n=124) and the control group(n=144)(all P>0.05). But there were significant differences in PSA [17.5(6.5, 23.0)ng/ml and 11.5(6.3, 12.0)ng/ml], PSAD[0.316(0.128, 0.363)ng/ml 2 and 0.211(0.106, 0.256)ng/ml 2], prostate inflammation of the initial biopsy [70 (56.5%) and 32 (22.2%)] between the observation group and the control group(all P<0.05). According to the follow-up results after the initial biopsy, the two groups of repeated biopsy were compared.Furthermore, Logistic regression was used to conduct univariate and multivariate analysis to explore the risk factors of patients with PI-RADS>3 for positive repeated biopsy. At the same time, the receiver operating characteristic curve (ROC curve) was used to analyze the accuracy of the risk factors. Results:There were significant differences in repeated biopsy rate [ 27.4%(34/124)and 14.6%(21/144)], CsPCa detection rate[ 41.4%(14/34) and 4.8%(1/21)]between the observation group and the control group(all P<0.05). The positive rate of repeated biopsy in the observation group (41.1%) was higher than that in the control group (23.8%), but there was no statistical difference ( P=0.248). The risk of positive repeated biopsies in the observation group was 2.24 times than that in the control group. Univariate analysis found repeated biopsy PSA ( P =0.02, OR=1.438, 95% CI 1.161-1.896), PSA ratio (repeated biopsy PSA/initial biopsy PSA) ( P=0.011, OR=10.087, 95% CI 1.714-59.36) were risk factors for positive of repeated biopsy in patients with PI-RADS score >3. Multivariate analysis also found that repeated biopsy PSA ( P=0.017, OR=1.15, 95% CI 1.076-2.123), PSA ratio ( P=0.032, OR=10.2, 95% CI 0.883-116.168) were risk factors for positive repeated biopsy. ROC curve analysis, the accuracy of repeated biopsy PSA (AUC=0.971, P<0.001, 95% CI 0.926-1.000), PSA ratio (AUC=0.839, P=0.001, 95% CI0.707-0.971) to predict positive of repeated biopsy were high. The cut-off values were 21.3 ng/ml and 1.4, respectively. The accuracy was higher when combines repeated biopsy PSA with PSA ratio (AUC=0.993, P<0.001, 95% CI 0.974-1.000). Conclusions:Patients with negative PI-RADS score > 3 have a higher risk of missed diagnosis of CsPCa than those with PI-RADS score≤3. When PSA>21.3 ng/ml and PSA ratio>1.4 during follow-up, the possibility of missed diagnosis in the initial biopsy is high.

Objective: To investigate the clinical value of modified transperineal template-guided prostate biopsy (mTTPB) in the detection of prostate cancer. Methods: A total of 217 patients were enrolled in this study. All the patients were randomly divided into 2 groups. The control group (n=112) underwent transperineal template-guided prostate biopsy (TTPB) which was traditional transperineal template-guided 11-region biopsy. On the basis of the control group, the apex of prostate was divided into four areas for biopsy in the observation group (mTTPB). The positive rate of apex and the incidence of complications were analyzed. The prostatic specimens from the radical prostatectomy underwent whole mount sections examination. The prostate biopsy results were compared with the postoperative pathological results. Results: The average age of the control group and the observation group were (68.5±7.9) years and (67.3±8.5) years, PSA were (31.2±18.9) ng/ml and (29.7±19.5) ng/ml, prostate volume were (44.6±15.2) ml and (41.3±17.3) ml, respectively. In the control group, the positive rates of prostate cancer in 1-10 region were 24.1% (27/112), 27.7%(31/112), 23.2% (26/112), 28.6% (32/112), 26.8% (30/112), 25.0% (28/112), 26.8% (30/112), 19.6% (22/112), 25.9% (29/112), 25.0% (28/112), respectively, with an average of 25.3%. In the observation group, the positive rates in 1-10 region were 27.6% (29/105), 28.6% (30/105), 22.9% (24/105), 26.7% (28/105), 25.7% (27/105), 24.8% (26/105), 27.6% (29/105), 21.9% (23/105), 27.6% (29/105), 26.7% (28/105), respectively, with an average of 26.0%. There was no statistical difference between the two groups (P=0.904). The positive rate of apical prostate cancer in the control group and observation group was 37.5% (42/112) and 44.8% (47/105), respectively, and there was no statistical difference between the two groups (P=0.277). Patients were grouped according to PSA>20 ng/ml and PSA≤20 ng/ml. When PSA>20 ng/ml, the positive rate of apex was 58.6% (34/58) and 56.6% (30/53) respectively in the control group and the observation group, and there was no statistical difference between the two groups (P=0.830). When PSA≤20 ng/ml, the positive rate of apex was 14.8% (8/54) in the control group and 32.7% (17/52) in the observation group, with statistically significant differences (P=0.030). Before radical prostatectomy, 12 cases (57.1%) in the control group and 19 cases (73.1%) in the observation group showed apical invasion by biopsy. Results of whole mount sections examination in the control group showed that there were 19 cases (90.5%) with apical invasion, which was statistically different from that before surgery (P=0.035). The results of whole mount sections examination in the observation group showed that there were 23 cases (88.5%) with apex invasion, which had no statistical difference compared with that before surgery (P=0.291). There were no significant differences in the incidence of hematuria, fever, urinary retention and perineal discomfort between the observation group and the control group (all P>0.05). Conclusions mTTPB can significantly improve the detection rate of apical prostate cancer without increasing the incidence of complications, especially for patients with PSA≤20 ng/ml. Hence is safe and efficacious.
