Results: Serum concentrations of free and total PSA in forty dogs under study showed that healthy dogs had a maximum concentration of 0.98 ng/ml, a minimum of 0.03 ng/ml, with an overall mean of 0.98 ng/ml. 03 ng/ml, with an overall mean of 0.36 ng/ml of total PSA, while the free PSA concentration of the healthy animals analysed determined a concentration range from 0.1 ng/ml to 0.82 ng/ml in blood with a total mean of 0.39 ng/ml. Conclusion: No increase in serum concentration of free and total prostate antigen was obtained due to the low specificity of the blood test according to the results reported.

Evaluation of prostate-specific antigen and total serum acid phosphatase in prostatic carcinoma

Background: The importance of prostatic carcinoma and its detection has increased manifold over the last few decades. Total serum acid phosphatase (ACP) was the world’s first emerged clinically useful tumor marker in the 1940s and 1950s in patients with prostatic diseases. With the introduction of the prostatic specific antigen (PSA) test in the 1980s, which performed significantly better in screening and treatment programs bringing disfavor to the advent of ACP. Aims and Objectives: To determine serum PSA and total serum ACP in patients with prostatic cancer and benign prostatic diseases, followed by evaluation of these tumor markers. Materials and Methods: This study was conducted on 30 patients with histologically proven cases of prostatic carcinoma and compared against 30 patients as control with benign prostatic pathology, residing in Punjab who were admitted and treated with symptoms complex of prostatism or retention urine or other urinary complaints as the primary symptoms. PSA and ACP in serum were determined using ELISA test kit and King and Kind method, respectively. Results: The mean level of serum PSA was 81.19 ± 49.02 for cancer prostate and 4.975 for benign prostatic diseases, while the mean level of serum ACP was 5.22 ± 1.70 and 2.52 ± 2.27, respectively, for the cancer prostate and benign prostatic diseases showing statistically difference between study and control groups was highly significant as P < 0.0001. Conclusion: Statistical analysis and results of the present study indicated that although serum ACP has better specificity to PSA, yet later is a very sensitive tumor marker in prostate diseases for screening, diagnosis, and post-treatment follow-up.

Research advances on the relationship between non-alcoholic fatty liver disease and risk of prostatic diseases / 中华全科医师杂志

Non-alcoholic fatty liver disease (NAFLD) is a liver disorder related to metabolic syndrome, which is considered to be associated with risk of benign prostatic hyperplasia (BPH) and prostate cancer (PCa). It has been reported that NAFLD may serve as an independent predictive factor for BPH and International Prostate Symptom Score (IPSS). In addition, NAFLD may also contribute to identify the high risk population of PCa, and to predict biochemical recurrence and progression of PCa. The roles of NAFLD in BPH and PCa may be related to insulin resistance and metabolic abnormality that cause aberrant and malignant proliferation in the prostatic gland. Besides, chronic systemic inflammation and Toll-like receptor-associated immunization may also involve in the development of NAFLD-mediated BPH. This article reviews the current research evidence on the role of NAFLD in the development of BPH and PCa, indicating that early intervention of NAFLD may alleviate the progression of BPH and PCa.

Prostate volume measurement by multiparametric magnetic resonance and transrectal ultrasound: comparison with surgical specimen weight / Avaliação do volume prostático obtido por ressonância magnética multiparamétrica da próstata e ultrassonografia transretal comparado ao peso da peça cirúrgica

ABSTRACT Objective To assess accuracy of multiparametric magnetic resonance of the prostate to estimate gland volume, comparing the results with transrectal ultrasound and surgical specimen. Methods A retrospective study of 85 patients who underwent multiparametric magnetic resonance and transrectal ultrasound (for fusion image-guided biopsy) before radical prostatectomy. Prostate measurements were obtained from magnetic resonance axial and sagittal T2-weighted images and ultrasound; the prostate volume was determined using the ellipsoid formula. The results were compared with the surgical specimen weight. Maximum interval between multiparametric magnetic resonance imaging, transrectal ultrasound, and prostatectomy was 6 months. Results The prostate volume measured by multiparametric magnetic resonance imaging was 18-157cm3 (mean of 49.9cm3) and by transrectal ultrasound, 22-165cm3 (mean of 54.9cm3); the surgical specimen weight was 20-154g (mean of 48.6g), with no statistical differences. Based on the values obtained from imaging examinations, the prostate volume obtained was very close to the real prostatic weight, and the measures by multiparametric magnetic resonance were slightly more precise. Conclusion Prostate volume measured by multiparametric magnetic resonance imaging and transrectal ultrasound showed similar values, and excellent agreement with real prostate weight of the surgical specimens. Prostate volume measured by magnetic resonance has been increasingly used in the clinical practice, and its value enables appropriate therapeutic planning and control of patients.

RESUMO Objetivo Avaliar a acurácia da ressonância magnética multiparamétrica da próstata para estimativa do volume da glândula, comparando seus resultados com a ultrassonografia transretal e correlacionando com o volume obtido da peça cirúrgica. Métodos Estudo retrospectivo incluindo 85 pacientes submetidos à ressonância magnética e, posteriormente, à ultrassonografia transretal (para orientação de biópsia com fusão de imagens) e, a seguir, à prostatectomia radical. As dimensões prostáticas foram obtidas na ressonância a partir das imagens nos planos axial e sagital em sequências ponderadas em T2 e, assim como na ultrassonografia, o volume foi calculado a partir do método da elipsoide. Os valores foram comparados com o peso prostático pós-cirúrgico. O intervalo máximo entre a ressonância e ultrassonografia e prostatectomia foi de 6 meses. Resultados O volume prostático obtido por ressonância magnética foi de 18 a 157cm3(média de 49,9cm3); pela ultrassonografia transretal, foi de 22 a 165cm3(média de 54,9cm3); e o peso da peça cirúrgica foi de 20 a 154g (média de 48,6g), sem diferenças estatísticas. A partir do valor obtido por esses métodos de imagem, provou-se que o volume prostático obtido aproximou-se bastante do peso real da próstata, com discreta maior precisão das medidas obtidas por ressonância magnética multiparamétrica. Conclusão As medidas do volume prostático adquiridas pela ressonância magnética e pela ultrassonografia transretal são semelhantes entre si, com excelente concordância com os pesos reais das próstatas obtidos das peças cirúrgicas. A avaliação desse dado, a partir da ressonância, método cada vez mais utilizado na prática clínica, permite o adequado planejamento terapêutico e o controle dos pacientes.

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.

Molecular mechanism of Danggui Beimu Kushen Pills in treating prostatic diseases based on TCM-IP / 中草药

Objective To analyze the material basis and molecular mechanisms of Danggui Beimu Kushen (DBK) Pills in treating prostatic diseases based on the method of integrated pharmacology. Method The platform of Integrative Pharmacology of Traditional Chinese Medicine (TCM-IP, www.tcmip.cn) was utilized to predict the main active ingredients and functional targets of DBK Pills in treating prostatic disease, key targets were screened for enrichment analysis of pathways, and the network of “herb-core component-key target-main pathway” was constructed, and the possible mechanisms of DBK Pills in treating prostatic diseases were explored. Results A total of 532 candidate key targets for the treatment of prostatic diseases by DBK Pills were predicted, and 1 840 terms of gene function and 194 signal pathways were analyzed by gene ontology (GO) and KEGG, respectively. The network analysis of “herb-core component-key target-main pathway” showed that 65 core components were predicted, including 29 ingredients from Angelica sinensis, 11 from Fritillaria thunbergii and 26 from Sophora flavescens. Those predicted components acted on the key targets of prostatic diseases, such as transcription factor binding, negative regulation of apoptosis, et al, through the estrogen, apoptosis, chemokines and other signal pathways, and thus played a role in the regulation of cell cycle, apoptosis and proliferation imbalance, which might be the molecular mechanisms of DBK Pills for the treatment of prostatic disease. Conclusion DBK Pills regulate the development of BPH, prostate cancer and other diseases through multiple pathways with multi-component interacting with multiple targets.

Advantages of ultrasound-guided caudal epidural block over TIVA for transrectal ultrasound guided transrectal prostate biopsy / 中国医师杂志

Objective To compare the safety and efficacy of the caudal block and Total Intravenous Anesthesia (TIVA) for transrectal ultrasound (TRUS) guided prostate biopsy.Methods 60 elderly patients with transrectal ultrasound guided transperineal prostate biopsy were randomized into Group A and Group B.Patients in Group A received ultrasound guided caudal block (0.33％ ropivacaine 15 ml) and patients in Group B received TIVA.In operation room (T1),immediately before operation (T2) and at the end of operation (T3),mean artery pressure (MAP),heart rate (HR),breathing rate (BR) and pulse oxygen saturation (SpO2) were recorded.The patients in two groups were rated the level of mini-mental state examination (MMES) at 2 h,8 h and 24 h after operation.Complications during the whole study period were also evaluated.Results The values of MAP,HR and BR of T1 in group B were significantly lower than those at T2 (P＜0.05),and were lower than those in the group A (P ＜0.05).The MMSE value in group A [2 h (25.66 ± 1.71) and 8 h (26.13 ± 1.52)] was significantly higher than that in group B [2 h (27.96 ± 1.71) and 8 h (29.01 ± 0.77)] at after operation (P ＜ 0.05).The rate of usage of ephedrine (13％) and assisted ventilation (20％) in group B was higher.No significant differences were detected in side effects between the two groups.Conclusions Caudal block provides better anesthesia than TIVA for TRUS guided prostate biopsy without an increase of side effects,and it may be safely used during ambulatory surgery.

Objective To compare the effects of the different temperature of lavage fluid on the vital signs of the patients during the perioperative period of transurethral resection of prostate (TURP). Methods From June 2016 to June 2017,56 patients received TURP treatment in the First People's Hospital of Linhai were randomly selected. The patients were divided into the observation group and the control group by the random number method, with 28 cases in each group. All patients underwent TURP under continuous epidural anesthesia. The lavage fluid of the observation group was heated and kept at 37℃ . In the control group,the lavage fluid was not heated,the temperature was about 21℃ . The related indicators between the two groups were compared. The changes of 30min,45min and 60min mean arterial pressure (MAP),heart rate (HP),body temperature (T) and blood oxygen saturation (SaO2) in the two groups were observed before and during operation,and the hypothermia in two groups was compared. Results There were no statistically significant differences in the operation time,dosage of lavage fluid,weight of the resection of prostate tissue and amount of bleeding during the operation between the two groups(all P > 0. 05). At preoperation and intraoperative 30min,there were no statistically significant differences in MAP,HP,T,SaO2 between the two groups. At intraoperative 45min,60min,MAP levels in the observation group were (92. 14 ± 8. 63) mmHg, (92. 06 ± 8. 19) mmHg,respectively,which were significantly higher than those in the control group [(85. 33 ± 9. 01)mmHg,(79. 26 ± 9. 84)mmHg] (P < 0. 05). At intraoperative 45min,60min,the HR in the observation group were (79. 45 ± 8. 64) / min,(79. 50 ± 9. 06) / min,respectively,which were significantly higher than those in the control group [(72. 47 ± 8. 21) / min,(65. 44 ± 7. 10) / min] (all P < 0. 05). At intraoperative 45min,60min,T in the observation group were (36. 42 ± 0. 16)℃ ,(36. 12 ± 0. 20)℃ ,respectively,which were significantly higher than those in the control group [(36. 40 ± 0. 14)℃ ,(35. 84 ± 0. 23)℃ ] (P < 0. 05),but SaO2 had no statistically signif-icant difference between the two groups(P > 0. 05). The incidence rates of low temperature,induced arrhythmia in the observation group were 3. 57％ ,0. 00％ ,respectively,which were significantly lower than those in the control group (35. 71％ ,25. 00％ )(χ2 = 7. 240,P = 0. 007;χ2 = 5. 878,P = 0. 015).

Conclusion The irrigating solution maintained at room temperature can significantly improve the vital signs,reduce hypothermia and induced arrhythmia in patients.

Severe lower urinary tract symptoms due to anteriorly located midline prostatic cyst arising from the bladder neck in a young male: case report / Sintomas graves do trato urinário inferior em decorrência de cisto anteriormente localizado na linha mediana da próstata proveniente do colo vesical em um jovem do sexo masculino: relato de caso

ABSTRACT CONTEXT: Prostatic cysts are uncommon. These cysts are usually asymptomatic and are diagnosed incidentally during ultrasonographic examination. On rare occasions, they may cause drastic symptoms. CASE REPORT: We report on a case of severely symptomatic anteriorly located prostatic cyst arising from the bladder neck in a 30-year-old man presenting with lower urinary tract symptoms, without clinical evidence of benign prostatic hyperplasia. Transrectal ultrasonography (TRUS), computed tomography (CT) and cystourethroscopy demonstrated a projecting prostatic cyst that occupied the bladder neck at the precise twelve o'clock position. It was acting as a ball-valve, such that it obstructed the bladder outlet. Transurethral unroofing of the cyst was performed and the patient's obstructive symptoms were successfully resolved. Histopathological examination indicated a retention cyst. CONCLUSIONS: It should be borne in mind that midline prostate cysts can be a reason for bladder outlet obstruction in a young male. Such patients may have tremendous improvement in symptoms through transurethral unroofing of the cyst wall.

RESUMO CONTEXTO: Cistos prostáticos são incomuns. Esses cistos são geralmente assintomáticos e são diagnosticados incidentalmente durante o exame ultrassonográfico. Raramente podem causar sintomas importantes. RELATO DE CASO: Relatamos um caso sintomático de grave cisto prostático de localização anterior, originário do colo da bexiga de um homem de 30 anos de idade, que apresentou sintomas do trato urinário inferior, sem evidência clínica de hiperplasia prostática benigna. Ultrassonografia transretal (TRUS), tomografia computadorizada (CT) e cistouretroscopia demonstraram um cisto prostático saliente que ocupou o colo da bexiga na posição exata de 12 horas. O cisto estava agindo como uma válvula de esfera, obstruindo a saída da bexiga. Retirada da cobertura do cisto foi realizada por via transuretral e os sintomas obstrutivos do paciente foram resolvidos com sucesso. O exame histopatológico indicou um cisto de retenção. CONCLUSÕES: Deve ser lembrado que a linha média do cisto de próstata pode ser motivo de obstrução da saída da bexiga em um jovem do sexo masculino. Esses pacientes podem ter notável melhoria nos sintomas com retirada da cobertura por via transuretral da parede do cisto.

Purpose To compare dietary, lifestyle, clinical, anthropometric, genetic and prostatic features of Brazilian Indians and non-Indians (Amazon). Methods 315 men, 228 Indians and 89 non-Indians, ≥40 years old were submitted to digital rectal examination, serum prostate specific antigen (PSA), testosterone, TP53 and GSTP1 genotyping, anthropometric, lifestyle, dietary, personal and familial medical history. Prostatic symptoms were evaluated with the International Prostate Symptom Score (IPSS). Results Macuxis and Yanomamis represented 43.6% and 14.5% of Indians respectively who spontaneously referred no prostate symptoms. Mean IPSS was 7, range 3-19, with only 15% of moderate symptoms (score 8-19); Mean age was 54.7 years, waist circumference 86.6 cm, BMI 23.9 kg/m2. Yanomamis presented both lower BMI (21.4 versus 24.8 and 23.3, p=0,001) and prostate volume than Macuxis and “other ethnic groups” (15 versus 20, p=0.001). Testosterone (414 versus 502 and 512, p=0.207) and PSA (0.48 versus 0.6 and 0.41, p=0.349) were similar with progressive PSA increase with aging. Val/Val correlated with lower PSA (p=0.0361). Indians compared to control population presented: - TP53 super representation of Arg/Arg haplotype, 74.5% versus 42.5%, p<0.0001. -GSTP1 Ile/Ile 35.3% versus 60.9%; Ile/Val 45.9% versus 28.7%; Val/Val 18.8% versus 10.3%; p=0.0003. Conclusions Observed specific dietary, lifestyle, anthropometric and genetic profile for TP53 and GSTP1 may contribute to Brazilian Indian population prostate good health. .

Assessment of neurovascular bundles around the prostate：incremental value of hybrid three dimensional diffusion tensor imaging to standard T2 weighted imaging technique / 中华放射学杂志

Objective To determine whether hybrid three dimensional diffusion tensor imaging (3D DTI) contributes incremental value to standard T2WI technique for assessing neurovascular bundles (NVB) around the prostate. Methods This retrospective institutional review board-approved study included 69 consecutive patients with prostate tumor who underwent MRI including conventional T2WI and 3D DTI . DTI data were postprocessed and hybrid 3D DTI and axial T2W images were obtained. Three radiologists with one, five and thirteen years of experience in reading prostate MRI and one urologist with three years of surgical experience in urology who were blinded to patient data independently recorded their levels of preference on a five-point scale of the NVBs around the prostate on the basis of T2WI alone and hybrid 3D DTI and T2WI, respectively. The differences of scores of T2WI and hybrid 3D DTI and T2WI of the four doctors were compared by using nonparametric Wilcoxon rank. Results The average scores of hybrid 3D DTI to T2WI and alone T2WI to assess NVBs for 3 radiologists and one urologist were 4.4±0.6, 4.3±0.8, 4.2± 0.6, 4.9±0.3 and 2.9±0.8, 3.0±1.1, 1.6±0.7, 3.8±0.5, respectively. The hybird 3D DTI to T2WI improved the discrimination abilities of NVBs around the prostate for 3 radiologists and one urologist (Z values were-12.791,-9.737,-14.538,-14.901, P contributes significant incremental value to the standard T2WI technique for assessing NVB around the prostate.

The value of transrectal realtime tissue elastography in the differential diagnosis of prostatic lesions / 中华医学超声杂志（电子版）

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.

Objective To analyze the distribution of prostate diseases in the elderly in Beijing, and explore the clinical value of ultrasound in the detection of prostate diseases Methods Prostatic diseases were screened by transrectal ultrasonography by PHLIIPS iU22. The distribution of prostate diseases was compared between the elderly and the middle-aged. Results Benign prostatic hyperplasia, prostatic stone, prostate cyst and prostatitis accounted for 70.7%, 31.1%, 14.2% and 1.5% in elderly group, respectively, and the corresponding data were 33.7%, 13.0%, 4.5% and 9.1% in middle-aged group, respectively. They showed a statistical significance between the groups (P＜0.05). Benign prostatic hyperplasia, prostatic stone and prostatitis were associated with age (P＜0.05). The incidence of benign prostatic hyperplasia and prostatic stone increased sharply with increasing age by Spearman correlative analysis (P＜0.05), and the prostatitis decreased with ageing (P＜0.05). Conclusions Benign prostatic hyperplasia and prostatic stone were the very common prostate diseases in the elderly, and their incidence grows with the age. It has great clinical value to use transrectal ultrasonography in the detection of prostate diseases.

Towards the Prevention and Management of Prostatic Diseases in Nigeria: A Framework

The prevalence of prostatic diseases is reportedly high in Nigeria, and in some cases, it is comparable to figures from industrialised countries. However, to date, the research and policy responses in Nigeria are regrettably inadequate. The presence of “the double burden of diseases” and a limited appreciation of recent trends in prostatic diseases may be partly responsible for this situation. Given the frequently meagre healthcare budgetary allocations, it is pertinent to develop a properly thought-out plan for the prevention and management of prostatic diseases in Nigeria. A framework aimed at contributing to the development of such a plan is presented here. The development of a Central Prostatic Diseases Unit (CPDU) in the Federal Ministry of Health is advocated. The CPDU would be responsible for planning research and information dissemination programmes. Emphasis should be placed on targeting modifiable risk factors at the population level, proper surveillance to identify emerging trends, and research on both the operational dynamics and the efficacy of locally available herbs that could be useful in the management of prostatic diseases.

Hiperplasia benigna da próstata / Benign prostatic hyperplasia

A hiperplasia benigna da próstata (HPB) e o adenocarcinoma da próstata (CaP) possuem elevada prevalência em homens acima dos 50 anos. As duas patologias possuem forte caráter hereditário, sendo que na HPB a intensidade dos sinais clínicos determina, na maioria das vezes, a necessidade e o tipo de tratamento a ser instituído. Já no CaP a detecção precoce é fundamental para a cura do paciente e a doença localizada, normalmente, não produza sintomas. Há várias opções de tratamento para ambas as patologias, dependendo do quadro clínico do paciente, a simples observação vigilante, o tratamento medicamentoso e os procedimentos cirúrgicos. O prognóstico da doença depende da fase em que é detectada, sendo necessária orientação para realização de exames periódicos.

Hemorrhagic complications and risk factors in transrectal ultrasound-guided prostate biopsies / 中华超声影像学杂志

Objective To determine the rate of hemorrhagic complications and the possible risk factors in transrectal ultrasound(TRUS)guided prostate biopsies.Methods TRUS guided prostate biopsies were carried out in 252 patients.Chi-aquare test,t test,conditional Logistic regression were used to comparatively analyze the risk factors(age,presence of prostate cancer,the volume of prostate,arterial hypertension,diabetes mellitus,use of acetylsalicylic acid and anticoagulant,number of samples)between hemorrhagic patients and non-hemorrhagic groups.Results Hematuria was the most frequent sing in all complications,corresponding to 19.1% of the cases.According to the general feature analysis between two groups,age and the volume of the prostate were significant different.Multiple factor Loigistic regression analysis showed that patients with or without hemorrhagic complications were significant differences in age(OR=0.97,95% CI:0.942～1.000)and the volume of the prostate(OR=0.989,95% CI:0.9790～0.999).Patients with or without hematuria were significant differences in presence of prostate cancer(OR=0.479,95% CI:0.236～0.975),the volume of the prostate(OR=0.987,95% CI:0.976～0.999)and use of acetylsalicylic acid and anticoagulant(OR=3.589,95% CI:1.133～11.366).Conclusions TRUS guided prostate biopsy is a safe and effective procedure.Age and the volume of prostate are influencing factors for hemorrhagic complications.Presence of prostate cancer and the volume of prostate are influencing factors for hematuria.Use of acetylsalicylic acid and anticoagulant are risk factors for hematuria after biopsy.
