Sonographic correlations between intravesical prostatic protrusion and bladder outlet obstruction in patients with symptomatic benign prostatic hyperplasia in Ibadan, Nigeria

Evaluating bladder outlet obstruction (BOO) in patients with prostatic enlargement may reflect the severity of the disease and aid in predicting the treatment outcome. Objectives: To determine the sonological correlation between intravesical prostatic protrusion and bladder outlet obstruction in patients with symptomatic benign prostatic enlargement. Methods: This prospective study was conducted over one year at the Department of Radiology, University College Hospital, Ibadan. A transabdominal ultrasound scan of the urinary bladder and prostate gland was carried out on patients with prostatic enlargement and BOO. The intravesical prostatic protrusion, pre-and post-void urine volumes, prostate volume and bladder wall thickness were measured. Results: A total of 132 men aged 43 to 90 years (mean age: 63.8±8.64 years) were studied. The median size of the intravesical prostatic protrusion (IPP) was 7.25 mm (IQR: 0.00 mm; 14.9 mm). The mean prostate volume was 63.3ml±36.0ml. Most subjects (55; 41.7%) had a prostate volume above 60ml, and most patients (101, 77.2%) had bladder wall thickness less than 5mm. The mean bladder wall thickness was 4.26mm±1.54mm. There was a statistically significant correlation between IPP and pre-void urine volume and prostate volume (p = 0.002 and <0.001, respectively). Patients over 70 years had increasing IPP and post-void urine, which lacked statistical significance (p =0.15). Conclusion: The severity of bladder outlet obstruction was reflected in the pre-void urine volume, which correlated with the size of IPP

Vigilância ativa do câncer de próstata - um conceito em evolução / Active surveillance of prostate cancer - an ongoing concept

A vigilância ativa é a solução encontrada pela urologia para a condução de tumores prostáticos com características de pouca agressividade. Desenvolvida especialmente após as polêmicas que envolveram a validade do rastreamento, essa abordagem vem sendo consolidada como a melhor maneira de se evitar o tratamento desnecessário do câncer de próstata e precisa ser compreendida por todos os médicos que lidam com a saúde do homem.

Active surveillance is the solution found by urology to deal with low-aggressivity prostate tumours. Having been developed following controversies over screening strategies, this has been considered the best approach to avoid unnecessary treatment of prostate cancer and such a concept needs to be well understood by every medical doctor who deals with men's health.

Elevated prostate volume index and prostatic chronic inflammation reduce the number of positive cores at first prostate biopsy set: results in 945 consecutive patients

ABSTRACT Objective To assess the association between prostate volume index (PVI), and prostatic chronic inflammation (PCI) as predictors of prostate cancer (PCA). PVI is the ratio between the central transition zone volume (CTZV) and the peripheral zone volume (PZV). Materials and methods Parameters evaluated included age, prostate specific antigen (PSA), total prostate volume (TPV), PSA density (PSAD), digital rectal exam (DRE), PVI, PCI and number of positive cores (NPC). All patients underwent baseline 14-core, trans-perineal random biopsies. Associations of parameters with the NPC were investigated by univariate and multivariate linear regression analysis. Results Between September 2010 to September 2017, 945 patients were evaluated. PCA was detected in 477 cases (50.7%), PCI in 205 cases (21.7%). PCA patients, compared to negative cases, were older (68.3 vs. 64.4 years) with smaller TPV (36 vs. 48.3mL) and CTZV (19.2 vs. 25.4), higher PSAD (0.24 vs. 0.15ng/mL/mL), further PVI values were lower (0.9 vs. 1.18) and biopsy cores less frequently involved by PCI (9.4% vs. 34.2%).High PVI and the presence of PCI were independent negative predictors of NPC in model I considering PSA and TVP (PVI, regression coefficient, RC -0,6; p=0.002) and PCI (RC -1,4; p <0.0001); and in model II considering PSAD (PVI:RC -0,7; p <0,0001; and PCI: RC -1,5; p <0.0001). Conclusions High PVI and the presence of PCI lowered the mean rate of NPC and is associated with less aggressive tumor biology expressed by low tumor burden. PVI can give prognostic information before planning baseline random biopsies. Confirmatory studies are required.

Densidad del antígeno prostático en el diagnóstico de cáncer de próstata / Prostate antigen density in the diagnosis of prostate cancer

El cáncer de próstata es un problema de salud pública a nivel mundial, el cual clásicamente se sospecha por alteració en el antígeno prostático (PSA) y/o tacto rectal (TR) y se confirma con biopsia prostática. No obstante, existen otros marcadores como la densidad del PSA (DPSA) que se emplean para determinar la necesidad de una biopsia. Objetivo: Verificar la utilidad actual de la DPSA como herramienta diagnóstica para cáncer de próstata. Métodos: Es un estudio descriptivo, prospectivo, tipo transversal, la selección de la muestra se efectuó mediante muestreo no probabilístico intencional, quedando integrada por el número de pacientes con criterios de biopsia prostática que acudieron al Servicio de Urología del Hospital Universitario de Caracas durante los meses de junio -julio del 2014. El análisis estadístico se realizó con el programa SPSS/PC versión 25.0. Resultados: El estudio estuvo conformado por 100 pacientes con edad media de 65±7,7. La tasa de detección de cáncer de próstata fue del 38% tomando en cuenta los criterios convencionales (PSA y TR), sin embargo, cuando el criterio es la DPSA se redujo el número de pacientes a 33 de los cuales el 69,7% (n 23) presentaron cáncer de próstata. Conclusión: La DPSA es una herramienta útil para ser usada como criterio para la realización de biopsia prostática con una tasa de detección general del 60,52% lo cual supera por si sola a los métodos de despistaje convencionales como lo son el valor del PSA y el tacto rectal(AU)

Prostate cancer is a public health problem worldwide, which is classically suspected due to alteration in prostatic antigen (PSA) and / or rectal examination (RE) and confirmed by prostate biopsy. However, there are other markers such as PSA density (DPSA) that are used to determine the need for a biopsy. Objective: To verify the actual usefulness of PSA density as a diagnostic tool for prostate cancer. Methods: Prospective, descriptive, cross-sectional, the selection of the sample was performed by intentional nonprobabilistic sampling, being composed of the number of patients with prostate biopsy criteria who attended the department of urology at University Hospital in Caracas during the months of june -july 2014. Statistical analysis was performed using SPSS / PC Version 25.0 program. Descriptive statistics were used. Results: e study consisted of 100 patients with a mean age of 65 ± 7.7. e detection rate of prostate cancer was 38% taking into account the conventional criteria (PSA and RE), however when the criterion is the DPSA the number of patients was reduced to 33 of which 69.7% (n 23) prostate cancer. Conclusion: e DPSA is a useful tool to be used as a criterion for performing a prostate biopsy overall detection rate of 60.52% which exceeds by itself to conventional screening methods such as the value of PSA and DRE(AU)

Prospective comparison of the novel visual prostate symptom score (VPSS) versus the international prostate symptom score (IPSS), and assessment of patient pain perception with regard to transrectal ultrasound guided prostate biopsy

OBJECTIVE: To compare the International Prostate Symptom Score (IPSS) and novel Visual Prostate Symptom Score (VPSS) in patients with lower urinary tract symptoms (LUTS), to correlate scores with uroflowmetry and prostate volume and assess patient perceptions regarding pain prior to, and after prostate biopsy. Materials and methods: Patients with LUTS who had an indication for transrectal ultrasound (TRUS) biopsy were included. Patients completed the IPSS-, VPSS- and prostate biopsy pain assessment questionnaires. Assessment included uroflowmetry, post- void residual volume and prostate volume (measured with TRUS). RESULTS: One hundred men were included. There were statistically significant correlations between the VPSS score and IPSS score (correlation coefficient (r) = 0.802); VPSS and Qmax (r = -0.311); VPSS and. Qave (r = -0.344); prostate volume with VPSS (r = 0.194) and Qmax (r = -0.260). The VPSS was quicker to complete than the IPSS (mean 100 vs. 165 seconds). The mean anticipated pain score before biopsy was 2.8 (range 0-6), and after biopsy (experienced pain) it was 1.8 (range 0-5). The pain during biopsy was less than expected in 67% of patients. CONCLUSION: In men with LUTS scheduled to undergo prostate biopsy, the VPSS score correlated positively with the IPSS score. Men with limited education take less time to complete the VPSS. Patient's perception of expected pain or discomfort during TRUSguided prostate biopsy was significantly higher than the pain actually experienced during biopsy. Men with lower education level had significantly higher expectation of pain prior to biopsy, but similar pain during biopsy

Comparison of Seropositivity to Trichomonas vaginalis between Men with Prostatic Tumor and Normal Men

Trichomoniasis is the most common curable sexually-transmitted infection. Most Trichomonas vaginalis-infected men are asymptomatic and can remain undiagnosed and untreated, and this has been thought to result in chronic persistent prostatic infection. Chronic inflammation is regarded as the major factor in the pathogenesis and progression of benign prostatic hyperplasia (BPH) and prostatic cancer (PCa). The aim of this study is to identify seropositivity to T. vaginalis in men with prostate tumors (BPH or PCa) visited to Hanyang University Hospital. A total of 183 men were enrolled between October 2013 and November 2014. They consisted of 139 with BPH (mean age: 64.0±0.07) and 44 with prostate cancer (mean age: 73.3±0.18). We carried out ELISA to identify the seropositivity to T. vaginalis. Mixed lysate antigen extracted from 8 strains of T. vaginalis was used in the ELISA. Also 58 male outpatients visited to Health Promotion Center in Hanyang University Hospital were evaluated for comparing group. As a results, seropositivity to T. vaginalis in patients with prostatic diseases was 19.7% (BPH: 18.7%, PCa: 22.7%) and it was significantly higher than the 1.7% of the comparing healthy group (P=0.001). Therefore, prostatic tumor showed higher seropositivity against T. vaginalis than normal men. As far as we know, this is the first report about seroprevalence in prostatic tumor in Korea.

Comparison of Two PCR Assays for Trichomonas vaginalis

PCR is known to be the most sensitive method for diagnosing Trichomonas vaginalis infections. This study aimed to compare the sensitivity of a PCR assay for trichomoniasis (HY-PCR) developed in Hanyang University with the use of a Seeplex Ace Detection Kit®, using urine collected from four Korean men with prostatic disease. Overall, HY-PCR was more sensitive than the Seeplex Kit. The use of Chelex 100 is recommended for DNA isolation in order to increase the sensitivity of the PCR test.

Accidental cystectomy during laparoscopic excision of prostatic utricle cyst - a rare complication

ABSTRACT Prostatic utricle cyst is a rare congenital anomaly. Symptomatic cysts require treatment. Surgical excision is the treatment of choice, but is challenging due to close proximity to vas deferens, ejaculatory ducts, bladder, prostate, rectum and pelvic nerves. Complications include rectal injury, ureteral injury, impotence, infertility and faecal incontinence. We here report a rare complication in which bladder was accidentally removed during laparoscopic excision of prostatic utricle cyst. To best of our knowledge such a complication has never been reported previously. We also describe the possible cause of this accident and suggest ways to prevent this disastrous complication.

Estudo dos sintomas, volume prostático e fluxometria em pacientes oligo/assintomáticos para o trato urinário inferior / Study of symptoms, prostatic volume and flowometry in oligo/asymptomatic patients for the lower urinary tract

RESUMO Introdução: A hiperplasia prostática benigna (HPB) é uma patologia bastante incidente, estando diretamente associada ao processo de senilidade, cuja prevalência pode atingir em torno de 75% dos homens com idade superior a 70 anos com impacto negativo significativo na qualidade de vida. Classicamente, se estabeleceu que tamanho prostático não se correlaciona com grau de obstrução, nem severidade de sintomas. Todavia, estudos recentes passaram a questionar esse aforisma ao notaram que o aumento do tamanho prostático é um preditor significativo de maior risco para progressão de STUI/HPB em homens com sintomas pré-existentes. Objetivos: Analisar a relação entre tamanho prostático, PSA total e fluxo urinário em pacientes oligo/assintomáticos para o trato urinário inferior que apresentam IPSS ≤ 7. Ainda, avaliamos a influência da idade sobre essas variáveis. Métodos: Este estudo envolveu 80 pacientes atendidos no Serviço de Urologia do Hospital do Servidor Público Municipal de São Paulo (HSPM) com diagnóstico clínico de HPB e ausência de sintomas ou sintomas leves do trato urinário inferior (IPSS ≤ 7), no período de outubro de 2016 a julho de 2018. Todos os pacientes incluídos foram submetidos a USG de próstata para avaliação do tamanho prostático, fluxometria para estudo do fluxo urinário e dosagem sanguínea do PSA total. Idade também foi estudada para avaliarmos seu papel nas características e na evolução da HPB. Resultados: A partir da análise dos dados coletados e considerando a análise descritiva, 68,7% dos pacientes tinham menos que 65 anos, 62,5% apresentaram próstatas ≥ 30 g, 92,5% tinham PSA total < 4 ng/dL e 78,7% mostraram fluxo urinário ≤ 15 ml/s. Quando estudamos analiticamente os dois grupos divididos por idade maior x menor 65 anos, observamos diferenças estatísticas para o PSAT (p=0,005) e o fluxo urinário (p=0,04). Conclusão: A maioria dos pacientes tinha menos que 65 anos, volume prostático maiores, níveis de PSA mais baixos e fluxo urinário inferior àquele considerado normal para indivíduos do sexo masculino. O PSAT e o fluxo urinário estão relacionados com a evolução da HPB. Palavras-chave: HPB, PSA, IPSS, fluxometria, idade.

Ultrasound detection of prostatic calculi as a parameter to predict the appearance of hematospermia after a prostate biopsy

ABSTRACT Purpose: We evaluated the correlation between prostate calculi and hematospermia in patients undergoing prostate biopsy, and its impact on sexual activity of patients. Materials and Methods: A single-center prospective randomized study of 212 patients referred for transrectal ultrasound-guided prostate biopsy (TRUSBx) was performed. All patients were divided into two groups: Group A (GA), 106 patients with moderate/marked presence of prostatic calculi visualized by TRUS; Group B (GB), 106 patients with absence/scarce of prostatic calcifications. Patients were handed questionnaires to obtain a validated data on the duration and impact of hematospermia on sexual activity. The anxiety scores were recorded using a visual analogue scale. Results: No significant difference was noted between the two groups when comparing age, preoperative PSA level, prostate volume, and biopsy number, except for digital rectal examination (DRE) findings. Post-biopsy results of patients included in GA revealed that the complication of hematospermia was present in 65.1%, while in GB was present in 39.7% (p<0.001). On multivariate analysis for identifying significant preoperative predictors of hematospermia, which included variables of age, PSA, prostate volume, and prostate cancer were not shown to be significant predictors of hematospermia, except DRE and prostate calculi (p<0.001). The mean anxiety score was 3.7±2.8 in GA and 2.3±1.9 in GB, respectively (p<0.001). Conclusions: Prostatic calculi are an independent predictive factor of severe hematospermia after TRUSBx on the basis of multivariate analysis, but don't affect the positive rate of prostate cancer. Patients should be adequately counselled before TRUSBx to avoid undue anxiety and alterations in sexual activity.

Analysis of lower urinary tract disease of dogs / Análise de doenças do trato urinário inferior em cães

Lower urinary tract diseases (LUTD) include different conditions that affect the urinary bladder, urethra and prostate. The objective of this study was to determine the frequency of different related diseases, to characterize the population affected, and to determine risk factors in dogs. The clinical cases were diagnosed with LUTD through physical examination, and clinical laboratory and imaging studies. Male dogs had a greater predisposition to present a LUTD. Dogs from 3 months to 18 years with a median of 8 years were affected, and the most affected breeds were Poodle, Labrador, German shepherd, Schnauzer, Cocker Spaniel and Chihuahua. The LUTD presented with the following frequencies: bacterial urinary tract infection 34.02%; micturition disorders 22.68%; urolithiasis 20.61%; prostatic disease 14.43%; traumatic problems 8.24%. Sixty-seven per cent of the cases were specific diseases, such as uncomplicated and complicated bacterial urinary tract infections, urinary retention of neurologic origin and silica urolithiasis.(AU)

Doenças do trato urinário inferior (DTUI) incluem várias condições clínicas que afetam a bexiga, próstata e uretra. O objetivo deste estudo foi determinar a frequência de diferentes doenças relacionadas, caracterizar a população afetada, e determinar os fatores de risco em cães. Os casos clínicos com DTUI foram diagnosticados através de exame físico, estudos laboratoriais e de imagem. Os cães machos apresentam uma maior predisposição para DTUI. Foram afectados cães com idades compreendidas entre os 3 meses a 18 anos, com uma mediana de oito anos, sendo as raças mais predispostas os Poodle, Labrador, Pastor Alemão, Schnauzer, Cocker Spaniel e Chihuahua. A etiologia DTUI apresentou as seguintes frequências: 34,02% foram originadas em infecção do trato urinário inferior; 22,68% em distúrbios miccionais; 20,61% em urolitíase; 14,43% em doença prostática; 8,24% em problemas traumáticos. Sessenta e sete por cento dos casos de DTUI estavam associados a doenças específicas, tais como infecções bacterianas do trato urinário não complicadas e complicadas, retenção urinária neurogénica e urolitíase por sílica.(AU)

Management of prostate abscess in the absence of guidelines

ABSTRACT In contemporary practice, the number of patients presenting with prostatic abscess have significantly declined due to the widespread use of antibiotics. However, when faced with the pathology, prostatic abscess tends to pose a challenge to clinicians due to the difficulty of diagnosis and lack of guidelines for treatment. Treatment consists of an array of measures including parenteral broad-spectrum antibiotic administration and abscess drainage.

Does MRI help in the pre - operative evaluation of pelvic fracture urethral distraction defect? - a pilot study

ABSTRACT Objectives To study the usefulness of MRI in preoperative evaluation of PFUDD. Can MRI provide additional information on urethral distraction defect (UDD) and cause of erectile dysfunction (ED)? Materials and Methods In this prospective study, consecutive male patients presenting with PFUDD were included from Feb 2011 till Dec 2012. Those with traumatic spinal cord injury and pre-existing ED were excluded. Patients were assessed using IIEF questionnaire, retrograde urethrogram and micturating cystourethrogram (RGU+MCU) and MRI pelvis. Primary end point was erectile function and secondary end point was surgical outcome. Results Twenty patients were included in this study. Fourteen patients (70%) were ≤40years; fifteen patients (75%) had ED, seven patients (35%) had severe ED. MRI findings associated with ED were longer median UDD (23mm vs. 15mm, p=0.07), cavernosal injury (100%, p=0.53), rectal injury (100%, p=0.53), retropubic scarring (60%, p=0.62) and prostatic displacement (60%, p=0.99). Twelve patients (60%) had a good surgical outcome, five (25%) had an acceptable outcome, three (15%) had a poor outcome. Poor surgical outcome was associated with rectal injury (66.7%, p=0.08), cavernosal injury (25%, p=0.19), retropubic scarring (18.1%, p=0.99) and prostatic displacement (16.7%, p=0.99). Five patients with normal erections had good surgical outcome. Three patients with ED had poor outcome (20%, p=0.20). Conclusions MRI did not offer significant advantage over MCU in the subgroup of men with normal erections. Cavernosal injury noted on MRI strongly correlated with ED. Role of MRI may be limited to the subgroup with ED or an inconclusive MCU.

Effect of short message service reminders on adhrence to follow-up of national annual prostatic digital rectal examination campaign participants: A randomized controlled pilot study

INTRODUCTION: National annual prostatic digital rectal exam (DRE) campaign advocated by the Philippine Urological Association (PUA) started 2 decades ago in over 60 urological centers in the country. It is being used as a tool to educate Filipinos regarding benign and malignant prostate diseases. However, after each campaign, most patients were lost to follow-up leading to delay in diagnosis and low adherence to medications.OBJECTIVE: To evaluate the effect of short message service (SMS) in the adherence to follow-up of participants after a campaign.METHODS: The investigators enrolled 126 participants aged 40 years old and above with significant LUTS and/or a prostate cancer suspect, in a two arm, parallel, randomized controlled pilot study at the Jose R. Reyes Memorial Medical Center (center with the most number of participants annually in the Philippines). Participants received daily SMS text messages for 3 days (n = 63) or usual care (n = 63). The primary outcome was follow-up at the outpatient clinic within 1 month after campaign. The investigators used Epi Info version 7 to analyze the data.RESULTS: Among participants receiving SMS, 21/63 (33.3%) returned, compared to 5/63 (7.94%) in the control group. The relative risk [RR] = 4.2, odds ratio = 5.8 and uncorrected chi-square (X2) = 12.4, at 95% confidence inetrval; p = 0.000429).CONCLUSION: This pilot study illustrated the feasibility of using SMS reminder among Filipino national prostatic DRE participants to improve adherence to follow-up. However, further research needs to be done to investigate the impact on adherence to medications and delay in diagnosis.

Obesity as a Risk Factor for Prostatic Enlargement: A Retrospective Cohort Study in Korea / 대한배뇨장애요실금학회지

PURPOSE: We aimed to evaluate obesity, a risk factor of metabolic syndrome, and its association with prostatic enlargement in a retrospective cohort in Korea. METHODS: Baseline data were obtained from the Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population (KoGES-ARIRANG). Between March 2015 and November 2015, 2,127 male participants of KoGES-ARIRANG were invited to the Korean Prostate Health Council Screening Program, and 602 participants underwent urological examination, including serum prostate specific antigen measurement and transrectal ultrasonography, and completed the International Prostate Symptom Score questionnaire. The data for 571 participants were analyzed, after excluding 31 men who had a history of prostatic disease or testosterone replacement, or had undergone a prior prostatic surgery or procedure. RESULTS: Among components of metabolic syndrome, waist circumference had a statistically significant linear correlation with incremental increases in prostate volume (B=0.181, P=0.004). Abdominal obesity as determined by anthropometric measures including body mass index (odds ratio [OR], 1.205; 95% confidence interval [CI], 1.088–1.336), waist circumference (OR, 1.073; 95% CI, 1.032–1.115), body fat (OR, 1.126; 95% CI, 1.056–1.202), and visceral fat composition (OR, 1.667; 95% CI, 1.246–2.232) was significantly associated with the presence of high-volume benign prostatic hyperplasia (BPH) (prostate volume≥ 40 mL). Furthermore, the highest quartile of serum leptin (OR, 3.541; 95% CI, 1.103–11.365) and adiponectin levels (OR, 0.315; 95% CI, 0.102–0.971) were significantly correlated with high-volume BPH compared to the lowest quartile of levels. CONCLUSIONS: Abdominal obesity and serum leptin level are positively associated with prostate growth, whereas serum adiponectin level is inversely associated with the presence of prostatic enlargement.

Unraveling Brazilian Indian population prostate good health: clinical, anthropometric and genetic features

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. .
