ABSTRACT
【Objective】 To explore the clinical efficacy and safety of pelvic floor magnetic and electrical stimulation combined with Kegel exercise training in the treatment of stress urinary incontinence (SUI) after minimally invasive surgery for benign prostatic hyperplasia (BPH). 【Methods】 A total of 52 patients with SUI after minimally invasive surgery for BPH treated during Jan.2016 and Feb.2022 were randomly divided into test group (n=26) and control group (n=26). The test group received pelvic floor magnetic and electrical stimulation and Kegel exercise training, while the control group received Kegel exercise training only. The treatment lasted for 3 months. The scores of International Consultation on Incontinence Modular Questionnaire Short Form (ICIQ-SF), 1 h pad test, International Prostate Symptom Score (IPSS) and Incontinence Quality of Life Questionnaire (I-QoL) were recorded and compared between the two groups before and after treatment. The adverse reactions were observed. 【Results】 The scores of ICIQ-SF, IPSS and I-QoL and 1 h pad test significantly decreased in both groups after treatment (P0.05), but after treatment, the scores of ICIQ-SF,IPSS,I-QoL and 1 h pad test were significantly lower in the test group than in the control group (P<0.05). No severe adverse reactions were observed. 【Conclusion】 Pelvic floor magnetic stimulation combined with Kegel exercise training is safe and effective for SUI after minimally invasive surgery for BPH.
ABSTRACT
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.

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.
ABSTRACT
Objective@#To evaluate the effect of multimodal analgesia using periprostatic nerve block anesthesia (PNB) combined with flurbiprofen in patients undergoing transperineal template-guided prostate biopsy (TTPB).@*Methods@#Totally 166 patients (aged (68.2±9.1) years, range: 47 to 81 years) who received TTPB from October 2017 to June 2018 at Department of Urology, Northern Jiangsu People′s Hospital Affiliated to Yangzhou University were enrolled prospectively. All the patients were randomly divided into 2 groups. The observation group (n=79) was given flurbiprofen axetil 1 mg/kg intravenously for half an hour before operation and lidocaine was used for PNB before the biopsy. The control group (n=87) was given normal saline combined with PNB. A visual analog scale (VAS) and visual numeric scale (VNS) were used to assess the patients′ pain and quantify their satisfaction at two time points: VAS-1 and VNS-1: during biopsy procedure, VAS-2 and VNS-2: 30 min after the procedure. The date were compared by t test, χ2 test, Fisher exact test and two-way repeated measures anova analysis between the 2 groups.@*Results@#The age, total prostate volume, serum prostate-specific antigen and the number of cores were comparable among the 2 groups (P>0.05). The VAS-1 scores of the control group and the observation group were 2.8±1.7, 1.9±1.2, respectively, and the VNS-1 were 3.1±0.7, 3.4±0.3, respectively. The VAS-1 were significantly lower in observation group than in control group (F=3.904, P=0.000). Conversely, the VNS-1 were higher in observation group (F=3.526, P=0.000). At 30-minute postoperative, the VAS-2 and VNS-2 were 0.7±0.4 and 3.7±0.2 in the control group, respectively. The VAS-2 and VNS-2 were 0.6±0.5 and 3.8±0.1 in the observation group, respectively. There were no significant differences in the pain scores or the satisfaction scores between the 2 groups (F=1.429, 2.825; P=0.136, 0.083). The incidence of overall complications was 26.4% (23/87) in the control group and 25.3% (20/79) in the observation group, with no statistical difference between the 2 groups (χ2=0.027, P=0.869). And the complications had no statistically significant difference among the 2 groups including hematuria, urinary retention, infection, hematospermia, vascular and neurological reactions, nausea, vomiting, dizziness, headache, and respiratory depression (P>0.05).@*Conclusion@#The multimodal analgesia induced by PNB and flurbiprofen could effectively relieve the pain for patients who received TTPB.
ABSTRACT
Androgen deprivation treatment (ADT) is the gold standard of care for patients with locally advanced or metastatic hormone-sensitive prostate cancer.However,most of these patients have developed to the castration-resistant prostate cancer (CRPC) after months or years through a series of different molecular mechanisms during ADT.So far,CRPC is still incurable and deadly,therefore,it is very important for researchers to study different molecular mechanism in the occurrence and development of CRPC,which may provide some new directions for targeted therapy.
ABSTRACT
Objective To investigate the influence factors of periprostatic nerve block (PNB) anaesthesia.Methods A total of 375 patients who underwent prostate biopsy under PNB were analyzed retrospectively from July 2014 to February 2018.It was evaluated the correlation of the anesthetic efficacy of PNB with age,prostate volume,PSA,body mass index,spouse,degree of education,occupation,diabetes history,operation time,number of cores and clinical stage.A visual analog scale (VAS) were used to assess pain of the patients.Univariate analysis was performed for each factor.Factors found to be significantly different that were further analyzed using multiple linear regression analysis.Results The average VAS score of all patients was 2.5 ± 1.4.Univariate analysis showed that the following factors were associated with the anesthetic efficacy of PNB:age (F =2.262,P =0.029),prostate volume (F =2.529,P =0.011),occupation (F =2.203,P =0.042),operation time (F =2.233,P =0.033),number of cores (F =2.401,P =0.016) and diabetes history (F =2.271,P =0.027).Multiple linear regression analysis showed that prostate volume (t =3.742,P ＜ 0.001),number of cores (t =4.252,P ＜ 0.001) and diabetes history (t =-2.242,P =0.032) were independent factors.The VAS score of patients with large volume prostate was higher than that of small volume prostate.The number of cores was high,and the VAS score was higher.However,diabetic patients had lower VAS score.Conclusions The anesthetic efficacy of PNB was poor in patients with larger prostate volume and more number of cores.However,patients with chronic diabetes had better pain tolerance.
