RESUMO
La segunda parte del Consenso Argentino Intersociedades de Infección Urinaria incluye el análisis de situaciones especiales. En pacientes con sonda vesical se debe solicitar urocultivo solo cuando hay signo-sintomatología de infección del tracto urinario, antes de instrumentaciones de la vía urinaria o como control en pacientes post-trasplante renal. El tratamiento empírico recomendado en pacientes sin factores de riesgo es cefalosporinas de tercera generación o aminoglucósidos. Las infecciones del tracto urinario asociadas a cálculos son siempre consideradas complicadas. En caso de obstrucción con urosepsis, deberá realizarse drenaje de urgencia por vía percutánea o ureteral. En pacientes con stents o prótesis ureterales, como catéteres doble J, el tratamiento empírico deberá basarse en la epidemiología, los antibióticos previos y el estado clínico. Antes del procedimiento de litotricia extracorpórea se recomienda pesquisar la bacteriuria y, si es positiva, administrar profilaxis antibiótica según el antibiograma. Cefalosporinas de primera generación o aminoglúcosidos son opciones válidas. Se recomienda aplicar profilaxis antibiótica con cefalosporinas de primera generación o aminoglúcosidos antes de la nefrolitotomía percutánea. La biopsia prostática trans-rectal puede asociarse a complicaciones infecciosas, como infecciones del tracto urinario o prostatitis aguda, principalmente por Escherichia coli u otras enterobacterias. En pacientes sin factores de riesgo para gérmenes multirresistentes y urocultivo negativo se recomienda realizar profilaxis con amikacina o ceftriaxona endovenosas. En pacientes con urocultivo positivo, se realizará profilaxis según antibiograma, 24 horas previas a 24 horas post-procedimiento. Para el tratamiento dirigido de la prostatitis post-biopsia trans-rectal, los carbapenémicos durante 3-4 semanas son el tratamiento de elección.
The second part of the Inter-Society Argentine Consensus on Urinary Tract Infection (UTI) includes the analysis of special situations. In patients with urinary catheter, urine culture should be requested only in the presence of UTI symptomatology, before instrumentation of the urinary tract, or as a post-transplant control. The antibiotics recommended for empirical treatment in patients without risk factors are third-generation cephalosporins or aminoglycosides. UTIs associated with stones are always considered complicated. In case of obstruction with urosepsis, an emergency drainage should be performed via a percutaneous nefrostomy or ureteral stenting. In patients with stents or ureteral prostheses, such as double J catheters, empirical treatment should be based on epidemiology, prior antibiotics, and clinical status. Before the extracorporeal lithotripsy procedure, bacteriuria should be investigated and antibiotic prophylaxis should be administered in case of positive result, according to the antibiogram. First generation cephalosporins or aminoglycosides are valid alternatives. The use of antibiotic prophylaxis with first-generation cephalosporins or aminoglycosides before percutaneous nephrolithotomy is recommended. Transrectal prostatic biopsy can be associated with infectious complications, such as UTI or acute prostatitis, mainly due to Escherichia coli or other enterobacteria. In patients without risk factors for multiresistant bacteria and negative urine culture, prophylaxis with intravenous amikacin or ceftriaxone is recommended. In patients with positive urine culture, prophylaxis will be performed according to the antibiogram, from 24 hours before to 24 hours post-procedure. For the targeted treatment of post-transrectal biopsy prostatitis, carbapenems for 3-4 weeks are the treatment of choice.

ABSTRACT Objectives: To investigate the characteristics of cases of NIH category I acute prostatitis developed after transrectal prostate biopsy and clarifiy the risk factors and preventive factors. Materials and Methods: We retrospectively reviewed the medical records of 3.479 cases of transrectal ultrasound-guided needle biopsies performed with different prophylactic antibiotherapy regimens at two different institutions between January 2011 and February 2016. The patients of Group I have received ciprofl oxacin (n=1.523, 500mg twice daily) and the patients of Group II have received ciprofl oxacin plus ornidazole (n=1.956, 500mg twice daily) and cleansing enema combination as prophylactic antibiotherapy. The incidence, clinical features and other related microbiological and clinical data, were evaluated. Results: Mean age was 62.38±7.30 (47-75), and the mean prostate volume was 43.17±15.20 (21-100) mL. Of the 3.479 patients, 39 (1.1%) developed acute prostatitis after the prostate biopsy procedure. Of the 39 cases of acute prostatitis, 28/3.042 occurred after the first biopsy and 11/437 occurred after repeat biopsy (p=0.038). In Group I, 22 of 1.523 (1.4%) patients developed acute prostatitis. In Group II, 17 of 1.959 (0.8%) patients developed acute prostatitis. There was no statistical difference between the two groups according to acute prostatitis rates (X2=2.56, P=0.11). Further, hypertension or DM were not related to the development of acute prostatitis (P=0.76, X2=0.096 and P=0.83, X2=0.046, respectively). Conclusions: Repeat biopsy seems to increase the risk of acute prostatitis, while the use of antibiotics effective for anaerobic pathogens seems not to be essential yet.

ABSTRACT Objective To The standard technique for obtaining a histologic diagnosis of prostatic carcinomas is transrectal ultrasound guided prostate biopsy. Acute prostatitis which might develop after prostate biopsy can cause periprostatic inflammation and fibrosis. In this study, we performed a retrospective review of our database to determine whether ABP history might affect the outcome of RP. Materials and Methods 441 RP patients who were operated in our clinic from 2002 to 2014 were included in our study group. All patients' demographic values, PSA levels, biopsy and radical prostatectomy specimen pathology results and their perioperative/ postoperative complications were evaluated. Results There were 41 patients in patients with acute prostatitis following biopsy and 397 patients that did not develop acute prostatitis. Mean blood loss, transfusion rate and operation period were found to be significantly higher in ABP patients. Hospitalization period and reoperation rates were similar in both groups. However, post-op complications were significantly higher in ABP group. Conclusion Even though it does not affect oncological outcomes, we would like to warn the surgeons for potential complaints during surgery in ABP patients.

BACKGROUND: Androgen deprivation results in massive apoptosis in the prostate gland. Macrophages are actively engaged in phagocytosing epithelial cell corpses. However, it is unknown whether microtubule-associated protein 1 light chain 3 alpha (LC3)-associated phagocytosis (LAP) is involved and contribute to prevent inflammation. METHODS: Flow cytometry, RT-PCR and immunohistochemistry were used to characterize the macrophage subpopulation residing in the epithelial layer of the rat ventral prostate (VP) after castration. Stereology was employed to determine variations in the number of ED1 and ED2. Mice were treated with either chloroquine or L-asparagine to block autophagy. RESULTS: M1 (iNOS-positive) and M2 macrophages (MRC1+ and ARG1+) were not found in the epithelium at day 5 after castration. The percentage of CD68+ (ED1) and CD163+ (ED2) phenotypes increased after castration but only CD68+ cells were present in the epithelium. RT-PCR showed increased content of the autophagy markers Bcl1 and LC3 after castration. In addition, immunohistochemistry showed the presence of LC3+ and ATG5+ cells in the epithelium. Double immunohistochemistry showed these cells to be CD68+ /LC3+ , compatible with the LAP phenotype. LC3+ cells accumulate significantly after castration. Chloroquine and L-asparagine administration caused inflammation of the glands at day 5 after castration. CONCLUSIONS: CD68+ macrophages phagocytose apoptotic cell corpses and activate the LAP pathway, thereby contributing to the preservation of a non-inflammed microenvironment. Marked inflammation was detected when autophagy blockers were administered to castrated animals.

AIMS: Maternal malnutrition by low protein diet is associated with an increased incidence of metabolic disorders and decreased male fertility in adult life. This study aimed to assess the impact of maternal protein malnutrition (MPM) on prostate growth, tissue organization and lesion incidence with aging. MAIN METHODS: Wistar rat dams were distributed into two groups, which were control (NP; fed a normal diet containing 17% protein) or a restricted protein diet (RP, fed a diet containing 6% protein) during gestation. After delivery all mothers and offspring received a normal diet. Biometrical parameters, hormonal levels and prostates were harvested at post-natal days (PND) 30, 120 and 360. KEY FINDINGS: MPM promoted low birth weight, decreased ano-genital distance (AGD) and reduced androgen plasma levels of male pups. Prostatic lobes from RP groups presented reduced glandular weight, epithelial cell height and alveolar diameter. The epithelial cell proliferation and collagen deposition were increased in RP group. Incidences of epithelial dysplasia and prostatitis were higher in the RP offspring than in the NP offspring at PND360. SIGNIFICANCE: Our findings show that MPM delays prostate development, growth and maturation until adulthood, probably as a result of low testosterone stimuli. The higher incidence of cellular dysplasia and prostatitis suggests that MPM increases prostate susceptibility to diseases with aging.

We present an unfrequent case of acute diverticulitis mimmicking acute prostatitis. Case report: A 72-year-old man suffering from hypogastric and genital pain, fever and dysuria, with an edematous and tender prostate at physical examination, was initially diagnosed of acute prostatitis. 24 hours later the patient developed left lower quadrant pain and abdominal distension. A CT scan was performed, showing pneumoperitoneum and acute sigmoid diverticulitis signs. The patient underwent a Hartmann's procedure.
Presentamos un caso infrecuente de diverticulitis aguda con manifestaciones clínicas sugerentes de prostatitis aguda. Caso clínico: Varón de 72 años, presenta dolor hipogástrico y en región genital, fiebre y disuria, palpándose una próstata edematosa y dolorosa al tacto rectal, por lo que es inicialmente diagnosticado de prostatitis aguda. A las 24 horas el paciente desarrolla un cuadro de distensión abdominal y dolor en fosa ilíaca izquierda. Una TC abdominal mostró neumoperitoneo y signos de diverticulitis aguda. Se intervino al paciente realizando una intervención de Hartmann.
