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.
ABSTRACT
Objective To evaluate the clinical efficacy of brachytherapy with 125I seeds implantation in patients with castration resistant prostate cancer (CRPC).Methods Twenty-eight patients with CRPC from February 2010 to December 2015 in Northern Jiangsu People's Hospital were analyzed retrospectively.Patients were divided into 2 groups according to different treatment methods.Control group (n =13) received endocrine therapy,and study group (n =15) underwent brachytherapy combined with endocrine therapy.The progression was defined as posttreatment prostate specific antigen (PSA) ≥ 125％ PSA of baseline level.PSA-progression-free survival (PFS),overall survival (OS) and quality of life (physical functioning,social functioning,general health,general physical discomfort,urinary symptoms and treatment-related symptoms) of 2 groups were compared using Kaplan-Meier analysis and log-rank test.Results The median PSA-PFS and OS of study group were 29(24,37) months and 37(32,50) months respectively,both of them were longer than those of control group (13(7,21) months,19(14,23) months;x2 =13.300,19.362,both P＜0.01).Comparing with control group,the physical functioning,social functioning,general health and general physical discomfort of study group were improved.Conclusion Brachytherapy can effectively prolong the survival of CRPC patients and improve the patients' life quality.
ABSTRACT
Objective To evaluate the erectile function following transperineal template-guided prostate saturation biopsy (TFPSB).Methods From June 2013 to October 2015,patients underwent prostate biopsy.All patients were indicated for biopsy according to the criteria of "Guidance on diagnosis and treatment of urology in China".Exclusion criteria include medical history of PCa,severe urinary tract infection,severe cardiovascular and cerebrovascular diseases or abnormal blood coagulation.All patients were divided into observation group (TT'PSB) or control group (traditional trans-perineal template-guided prostate biopsy,TTPB) according to patients' condition,pubic anatomy,PSA abnormality,rectal examination,imaging examination and pain tolerance,etc.Patients were evaluated for pre-biopsy erectile function with the international index of erectile function (IIEF-5).All pathology confirmed prostate cancer patients were excluded.Concomitant systemic diseases and medications that would interfere with erectile function were recorded.Patients who withdrew from the trial or used the drugs such 5-phosphodiesterase inhibitors for sexual activity improvement were excluded.Ninety-seven patients in observation group and 84 patients in control group underwent further evaluation with the IIEF-5 questionnaire at 1,3 and 6 months post-biopsy.Results The average age of the observation group and the control group were (64.1 ± 7.9) years and (61.8 ±8.9) years,PSA were (7.2 ± 3.7) ng/ml and (6.7 ± 3.4) ng/ml,prostate volume were (47.8 ±21.5)ml and (49.2 ±22.2) ml,and the BMI were (21.4 ±3.1) kg/m2 and (20.6 ±3.4) kg/m2,respectively.There was no significant difference between the two groups (P ＞ 0.05) in term of above patients' characteristics.The pre-biopsy IIEF-5 score of the observation group and the control group were 19.1 ±4.5 and 19.7 ±4.3,which had no significant difference (t =-0.890,P=0.375).One month after biopsy,the IIEF-5 of two groups were 17.4 ±4.8 and 18.2 ±4.5 respectively and both group had statistically significant difference when compared with pre-biopsy (both P ＜ 0.05),however,there was no statistical significance at 3 and 6 months after biopsy.Besides,no significant difference of the IIEF-5 score was detected between two groups in 1,3 and 6 months.Conclusions Although TTPSB may resulted in temporary (1 month) post-biopsy erection dysfunction,the erectile function recovered to pre-biopsy level at 3-6 months post-biopsy.TTPSB did not increase the risk of ED compared with traditional TTPB.

ABSTRACT
Objective To investigate the efficacy and safety of salvage radical prostatectomy for men with recurrent prostate cancer (PCa) after radiotherapy.Method Ten pathologically confirmed PCa patients who relapsed after radiotherapy from Jan.2008 to Dec.2013 were retrospectively reviewed.The mean age was (64.7 ±3.7) years,with range from 56 to 72 year.Local recurrence was confirmed by retransrectal biopsy.All patients had increased PSA and/or lower urinary tract symptoms.Pelvis MRI and bone scan were performed to detect lymph node involvement and bone metastasis.All patients received radical prostatectomy with standard pelvic lymphadenectomy.Seven received open surgery (open group),three patients underwent laparoscopic surgery (laparoscopic group).Postoperative complication and PSA level were compared.Results Salvage radical prostatectomies with lymph node dissection were performed in all patients without major complications.The mean operation time of open group versus laparoscopic group were (225 ± 57)min vs.(210 ± 80)min and the mean blood loss was (275 ± 49)ml vs.(260 ± 93) ml,both of which were with no significant difference (P ＞ 0.05).The average length of stay was (14 ± 4) vs.(8 ± 2) day with significant difference (P ＜ 0.05).No rectal injury was observed.Two (20％) patients were with positive margin,and three (30％) patients had postoperative complications,including one case of deep vein thrombosis,one case of incision infection and and one case of anastomotic leakage.After a mean of 20.6 months'follow-up,two patients (25％) reached biochemical recurrence.Conclusion Both open and laparoscopic salvage radical prostatectomies after radiotherapy failure were feasible.Largescaled prospective studies were needed to verify the long-term effectiveness.
