RESUMO

We reported an 8-year-old boy with panscleritis in left eye and right epididymitis after falling on the ground. Etiologic diagnosis played a key role in this case. Systemic examinations ruled out systemic autoimmune diseases, tumors, and infections as the cause of scleritis and suggested that the disease was caused by a local delayed-type hypersensitivity (DTH) induced by ocular trauma and was non-infectious. Still, the right epididymitis was infectious. Both conditions were treated successfully using steroids and antibiotics, respectively. Thus, early etiologic diagnosis and reasonable treatment are crucial to prevent visual loss.

RESUMO

Orchiepididymitis (OE) is a frequent cause of pediatric emergency department attendance in boys presenting with acute scrotum. The etiology of most episodes of OE remains unclear and there is no consensus regarding the correlation between OE and underlying genitourinary malformations. Whether imaging evaluation should comprise complete urinary tract ultrasonography (US) or voiding cystography is a subject of debate. The aim of this retrospective, single-center study was to analyze i) the number/type of urinary tract malformations detected by US following a first episode of OE in boys with no previously known malformation and ii) the frequency of associated urinary tract infection (UTI). We reviewed the records of 495 boys <16 years presenting to our pediatric emergency department with acute scrotum between January 2012 and December 2017. Patients with incomplete radiological data were excluded. Of 119 boys with a radiologically-confirmed first episode of OE, 99 had a complete urinary tract US and were included in the study. No genitourinary malformation was detected (0%). Urinary cultures showed UTI in 3/98 (3.1%) patients. Mean age at presentation was 9.7 years (standard deviation, 3.9) with a three-peak incidence of OE at 10-13 years, 4-5 years, and during infancy. Conclusion: Complete urinary tract US does not appear to be useful during a first episode of OE in countries with an antenatal US screening rate similar to Switzerland. The very low UTI rate suggests that a urinalysis is sufficient to investigate a first episode of OE and antibiotics should be reserved for positive urinalysis only.

RESUMO

BACKGROUND: To explore whether opening the external urethral orifice in the coronal sulcus can reduce the incidence of epididymitis after operating on hypospadias with prostatic utricle cyst (PUC) connecting to the vas deferens. Group A consisted of 3 patients with severe hypospadias and PUC undergoing cystostomy, hypospadias correction and urethroplasty, along with the relocation of the external orifice of the urethra to the coronal sulcus. Group B consisted of 4 patients having initial hypospadias repaired with meatus in the orthotopic position in the glans, presenting with multiple epididymitis after hypospadias surgery and unsuccessful conservative treatment. MR confirmed that all the Group B patients had PUC connecting to the vas deferens. Group B patients underwent urethral dilatation along with urethral catheterization, cutting of the original corpus cavernosum that encapsulated the urethra, and extension of the position of the external urethral orifice to the coronal sulcus. RESULTS: In group A, 3 children underwent bladder fistula removal 2 weeks after the operation. The penis developed normally without any complications. Four children in group B underwent stent removal 12 weeks after operation, and one patient was still stenosed and dilated again. All patients in group B were followed without epididymitis recurrence. CONCLUSIONS: For patients with hypospadias complicating with a PUC, connecting to one side of the vas deferens, the positioning of the external urethral orifice in the coronary sulcus would be helpful to reduce the occurrence of epididymitis.

RESUMO

As far as we know this is the first report on bulking agent injection into intravesical ectopic ejaculatory orifices reported in the English literature. During a follow-up period of 23 months, the child was free of episodes of epididymo-orchitis. Deflux injection in this rare anomaly of intravesical refluxing ducts had prevented irreversible damage to the testes from recurrent EO. Thus, it may be a better option than vasectomy when antibiotic treatment fails.

RESUMO

The present study was conducted to assess the semen parameters, complications and clinical effect of microsurgical varicocelectomy with testicular delivery (TD) for treatment of varicocele. Relevant studies were collected and reviewed systemically from PubMed, Medline, Embase, Web of Science, China National Knowledge Infrastructure databases and the Cochrane Library and a meta-analysis was performed. Relative ratio (RR), standardised mean difference (SMD) and their 95% confidence intervals (CIs) were adopted to estimate the outcome measures. Eight articles and a total of 1,139 subjects including 487 patients with TD in microsurgical varicocelectomy and 652 patients without TD were enrolled in this meta-analysis. The pooled RR indicated that microsurgical varicocelectomy with TD increased the incidence of orchiepididymitis (RR = 4.36, 95% CI = 1.12-16.99, p = 0.034) and scrotal oedema (RR = 4.25, 95% CI = 2.40-7.54, p = 0.000) than microsurgical varicocelectomy without TD postoperatively. In conclusion, compared to microsurgical varicocelectomy without TD, TD to further ligate the gubernacular veins in microsurgical varicocelectomy results in a higher incidence of orchiepididymitis and scrotal oedema and take longer operation time. However, TD may not have any beneficial influences on semen parameters, serum testosterone, varicocele occurrence, wound infection and natural conception.

RESUMO

Epididymitis is a commonly diagnosed disease associated with male infertility. However, little is known about the molecules that are involved in its development. This study was to identify critical genes associated with lipopolysaccharide-induced epididymitis and analyze the molecular mechanism of epididymitis through RNA sequencing. Experimental epididymitis models were generated by administering male Sprague-Dawley rats' lipopolysaccharide. A total of 1378 differentially expressed genes, including 531 upregulated and 847 downregulated genes, were identified in the epididymitis model rats compared with those in sham-operated rats by RNA sequencing. Functional enrichment analyses suggested that the upregulated genes were markedly enriched in inflammation-related biological processes, as well as in the tumor necrosis factor (TNF) signaling pathway, cytokine-cytokine receptor interactions, complement and coagulation cascades, and in the chemokine signaling pathway. Four downregulated genes (collagen type XXVIII alpha 1 chain [Col28α1], cyclin-dependent kinase-like 1 [Cdkl1], phosphoserine phosphatase [Psph], and fatty acid desaturase 2 [Fads2]) and ten upregulated genes (CCAAT/enhancer-binding protein beta [Cebpß], C-X-C motif chemokine receptor 2 [Cxcr2], interleukin 11 [Il11], C-C motif chemokine ligand 20 [Ccl20], nuclear factor-kappa-B inhibitor alpha [Nfkbiα], claudin 4 [Cldn4], matrix metallopeptidase 9 [Mmp9], heat shock 70 kDa protein 8 [Hspa8], intercellular cell adhesion molecule-1 [Icam1], and Jun) were successfully confirmed by real-time polymerase chain reaction. Western blot demonstrated that CDKL1 was decreased, while MMP9 and NFKBIA were increased in the experimental model group compared with those in the sham-operated group. Our study sheds new light on the understanding of the early response of the epididymis during bacterial epididymitis.

RESUMO

PURPOSE: To evaluate the role and success rate of urethral reconstruction in patients with urethral stricture previously treated with thermos-expandable Memokath™ urethral endoprosthesis. MATERIALS AND METHOD: A case series of patients with urethral stricture and Memokath™ endoprosthesis treated with urethroplasty is presented. Reconstruction was decided due to stricture progression or complications derived from primary stent treatment. Age, stricture and stent length, time between stent placement and urethroplasty, mode of stent retrieval, type of urethroplasty, complications and voiding parameters before and after urethroplasty were evaluated. Successful outcome was defined as standard voiding, without need of any postoperative procedure. RESULTS: Eight cases with bulbar urethra stricture were included. Memokath™ was endoscopically retrieved before urethroplasty in 6 (75%) and by open urethrotomy at the time of urethroplasty in 2 (25%). Technique of urethroplasty was dorso-lateral onlay buccal mucosa graft in 5 (62.5%) cases and excision and primary anastomosis, anastomotic urethroplasty, and dorsal onlay buccal mucosa graft in one (12.5%) case each. There was no failure at 26±21.5 months median follow-up. Total IPSS, QoL, Qmax and postvoid residual significantly improved (P<.05). The only complication presented was epididymitis and penile shortening in one patient (12.5%). CONCLUSIONS: Urethroplasty after re-stricture or other complications in patients with temporary Memokath™ urethral stent is a viable and definite option of reconstruction with excellent results in the short term and few complications. One-side dorsolateral onlay buccal mucosa graft augmentation is the optimal technique for this indication.

RESUMO

BACKGROUND: Mycobacterium bovis causing tuberculosis in animals is responsible for zoonotic tuberculosis in patients. Veterinary control measures and milk pasteurization has led to a significant decrease in human cases of M. bovis infections in developed countries. CASE PRESENTATION: We diagnosed recurrent M. bovis epididymitis in a 63-year old Caucasian man without any signs of pulmonary or disseminated disease. Relevant epidemiological expositions included camel milk drinking during prolonged travels in Niger, prior to initial clinical manifestations. The diagnosis was firmly established by mass spectrometry and DNA sequencing on epididymis surgical biopsy specimens. We detail therapeutic management which included surgical epididymectomy and hydrocele repair. CONCLUSION: As for other M. tuberculosis complex species, the genitourinary tract represents a frequent site of secondary dissemination and latency for M. bovis. Isolated epididymis infection is a newly documented manifestation of M. bovis disease.

RESUMO

INTRODUCTION: Urethrodeferential reflux is an underdiagnosed condition, and there is no consensus on its treatment. Our objective is to show our experience in the minimally invasive treatment of this disease using endoscopy. MATERIAL AND METHODS: We present 8 patients with recurrent suppurative orchitis due to urethrodeferential reflux treated endoscopically during the period 2008-2013. All patients presented unilateral orchitis. The minimum number of episodes of orchitis per patient prior to the operation was 3. The endoscopic treatment consists of ureteroscopy, locating the ejaculatory orifices and conducting an intraoperative contrast study to demonstrate the urethrodeferential reflux. Subejaculatory dextranomer/hyaluronic acid was subsequently injected in all the cases. RESULTS: The mean surgical time was 15min, and the procedure was outpatient for all patients. There were no postoperative complications, and the patients had good clinical progression. Only one case required a second injection of dextranomer/hyaluronic acid. The follow-up of these patients showed a complete resolution of the epididymitis and good testicular development, with a follow-up longer than 4 years in all cases. CONCLUSION: We propose this form of treatment as a minimally invasive, easily reproducible alternative that shows good long-term results in our small series of patients.

RESUMO

BACKGROUND: Current evidence suggests that chlamydia screening programmes can be cost-effective, conditional on assumptions within mathematical models. We explored differences in cost estimates used in published economic evaluations of chlamydia screening from seven countries (four papers each from UK and the Netherlands, two each from Sweden and Australia, and one each from Ireland, Canada and Denmark). METHODS: From these studies, we extracted management cost estimates for seven major chlamydia sequelae. In order to compare the influence of different sequelae considered in each paper and their corresponding management costs on the total cost per case of untreated chlamydia, we applied reported unit sequelae management costs considered in each paper to a set of untreated infection to sequela progression probabilities. All costs were adjusted to 2013/2014 Great British Pound (GBP) values. RESULTS: Sequelae management costs ranged from £171 to £3635 (pelvic inflammatory disease); £953 to £3615 (ectopic pregnancy); £546 to £6752 (tubal factor infertility); £159 to £3341 (chronic pelvic pain); £22 to £1008 (epididymitis); £11 to £1459 (neonatal conjunctivitis) and £433 to £3992 (neonatal pneumonia). Total cost of sequelae per case of untreated chlamydia ranged from £37 to £412. CONCLUSIONS: There was substantial variation in cost per case of chlamydia sequelae used in published chlamydia screening economic evaluations, which likely arose from different assumptions about disease management pathways and the country perspectives taken. In light of this, when interpreting these studies, the reader should be satisfied that the cost estimates used sufficiently reflect the perspective taken and current disease management for their respective context.

RESUMO

OBJECTIVE: To investigate the clinical application value of 8.5/11.5 F transurethral seminal vesiculoscopy in the diagnosis and treatment of refractory hematospermia. METHODS: We retrospectively analyzed 78 cases of refractory hematospermia diagnosed and treated by 8.5/11.5 F transurethral seminal vesiculoscopy from June 2012 to June 2014. The patients underwent serum PSA examination, transrectal ultrasonography, seminal vesicle ultrasonography, and pelvis CT or MRI before surgery, and all received transurethral seminal vesiculoscopy under the 8.5/11.5 F rigid ureteroscope. RESULTS: Operations were all successfully accomplished, which revealed abnormal opening of the ejaculatory duct in 5 cases, mucosal inflammatory hyperemia in the prostatic utricle and seminal vesicle in 78, dark red mucilage substance in the seminal vesicle in 34, seminal vesicle stones in 19, small polyp in the seminal vesicle in 2, and ejaculatory duct or seminal vesicle cyst in 4. All the patients received symptomatic treatment during the surgery. After surgery, hematouria was found in 13 cases, which disappeared within 2 weeks, pelvic hematoma in 1 case, which was cured by conservative treatment within 3 months, and epididymitis in 2 cases, which was controlled by anti-infection treatment. Hematospermia recurred in 3 cases during the 1-year postoperative follow-up. CONCLUSION: 8.5/11.5 F transurethral seminal vesiculoscopy, with its advantages of easy operation, wide field of vision, large channel for operation, and few complications, deserves general clinical application in the diagnosis and treatment of refractory hematospermia.

RESUMO

BACKGROUND: Acute epididymitis is an inflammation of the epididymis. It mostly occurs unilaterally and may spread to the testis ('epididymo-orchitis') if untreated. Increasing technological advances allow for an even more detailed examination of concurrent symptoms such as ejaculate changes and the whole spectrum of pathogenic agents, which ranges from sexually transmitted pathogens such as Chlamydia and gonococci to enterobacteria and, rarely, viruses. This review summarises major aspects of the disease including the latest scientific findings. METHODS: A selective literature search including the last 40 years was performed via Medline. RESULTS: With about 400 cases a year in 100 000 men, acute epididymitis is the most common urogenital infection in men. It occurs across all age groups including children. Despite the fact that bacterial ascension is aetiologically of utmost relevance, only one out of three men reports signs of dysuria or urethritis. In young, sexually active men, sexually transmitted pathogens are regularly found in addition to the characteristic enterobacteriae, even if these men have an unremarkable sexual history. 88% of epididymal abscess formations can be successfully treated without surgery. Patients with indwelling urethral catheters are at a high risk of multiple drug resistance and should be treated empirically with both a fluoroquinolone and a third-generation cephalosporin until antimicrobial susceptibility testing has been completed. About 40 out of 100 patients develop post-inflammatory sub-fertility. Here, virulence factors like haemolysin A produced by uropathogenic E. coli have a negative impact on semen parameters compared to those patients suffering from epididymitis induced by haemolysin A negative strains. With adequate antibiotic treatment there is no evidence for testicular atrophy. Only one out of 10 men relapses. These cases should be examined thoroughly for subvesical obstruction. Some of them may benefit from prophylactic vasectomy. CONCLUSIONS: This review presents key aspects of acute epididymitis, which are increasingly adopted in updated guidelines.

RESUMO

BACKGROUND: Magnetic resonance imaging-guided transurethral ultrasound ablation (MRI-TULSA) is a novel minimally invasive technology for ablating prostate tissue, potentially offering good disease control of localized cancer and low morbidity. OBJECTIVE: To determine the clinical safety and feasibility of MRI-TULSA for whole-gland prostate ablation in a primary treatment setting of localized prostate cancer (PCa). DESIGN, SETTING, AND PARTICIPANTS: A single-arm prospective phase 1 study was performed at three tertiary referral centers in Canada, Germany, and the United States. Thirty patients (median age: 69 yr; interquartile range [IQR]: 67-71 yr) with biopsy-proven low-risk (80%) and intermediate-risk (20%) PCa were treated and followed for 12 mo. INTERVENTION: MRI-TULSA treatment was delivered with the therapeutic intent of conservative whole-gland ablation including 3-mm safety margins and 10% residual viable prostate expected around the capsule. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary end points were safety (adverse events) and feasibility (technical accuracy and precision of conformal thermal ablation). Exploratory outcomes included quality of life, prostate-specific antigen (PSA), and biopsy at 12 mo. RESULTS AND LIMITATIONS: Median treatment time was 36min (IQR: 26-44) and prostate volume was 44ml (IQR: 38-48). Spatial control of thermal ablation was ±1.3mm on MRI thermometry. Common Terminology Criteria for Adverse Events included hematuria (43% grade [G] 1; 6.7% G2), urinary tract infections (33% G2), acute urinary retention (10% G1; 17% G2), and epididymitis (3.3% G3). There were no rectal injuries. Median pretreatment International Prostate Symptom Score 8 (IQR: 5-13) returned to 6 (IQR: 4-10) at 3 mo (mean change: -2; 95% confidence interval [CI], -4 to 1). Median pretreatment International Index of Erectile Function 13 (IQR: 6-28) recovered to 13 (IQR: 5-25) at 12 mo (mean change: -1; 95% CI, -5 to 3). Median PSA decreased 87% at 1 mo and was stable at 0.8 ng/ml (IQR: 0.6-1.1) to 12 mo. Positive biopsies showed 61% reduction in total cancer length, clinically significant disease in 9 of 29 patients (31%; 95% CI, 15-51), and any disease in 16 of 29 patients (55%; 95% CI, 36-74). CONCLUSIONS: MRI-TULSA was feasible, safe, and technically precise for whole-gland prostate ablation in patients with localized PCa. Phase 1 data are sufficiently compelling to study MRI-TULSA further in a larger prospective trial with reduced safety margins. PATIENT SUMMARY: We used magnetic resonance imaging-guided transurethral ultrasound to heat and ablate the prostate in men with prostate cancer. We showed that the treatment can be targeted within a narrow range (1mm) and has a well-tolerated side effect profile. A larger study is under way. TRIAL REGISTRATION: NCT01686958, DRKS00005311.

RESUMO

PURPOSE: We relied on a population-based case-control study (PROtEuS) to examine a potential association between the presence of histologically confirmed prostate cancer (PCa) and history of genitourinary infections, e.g., prostatitis, urethritis, orchitis and epididymitis. PATIENTS AND METHODS: Cases were 1933 men with incident PCa, diagnosed across Montreal hospitals between 2005 and 2009. Population controls were 1994 men from the same residential area and age distribution. In-person interviews collected information about socio-demographic characteristics, lifestyle and medical history, e.g., self-reported history of several genitourinary infections, as well as on PCa screening. Logistic regression analyses tested overall and grade-specific associations, including subgroup analyses with frequent PSA testing. RESULTS: After multivariable adjustment, prostatitis was associated with an increased risk of any PCa (OR 1.81 [1.44-2.27]), but not urethritis (OR 1.05 [0.84-1.30]), orchitis (OR 1.28 [0.92-1.78]) or epididymitis (OR 0.98 [0.57-1.68]). The association between prostatitis and PCa was more pronounced for low-grade PCa (Gleason ≤ 6: OR 2.11 [1.61-2.77]; Gleason ≥ 7: OR 1.59 [1.22-2.07]). Adjusting for frequency of physician visits, PSA testing frequency or restricting analyses to frequently screened subjects did not affect these results. CONCLUSION: Prostatitis was associated with an increased probability for detecting PCa even after adjustment for frequency of PSA testing and physician visits, but not urethritis, orchitis or epididymitis. These considerations may be helpful in clinical risk stratification of individuals in whom the risk of PCa is pertinent.

RESUMO

INTRODUCTION: Epididymitis in patients with anorectal malformation (ARM) represents a unique problem because unlike the general population, an underlying urinary tract problem is frequently identified. We review our experience with epididymitis in ARM population with an emphasis on examining urologic outcomes. MATERIALS AND METHODS: We performed a retrospective review of male patients with ARM cared for from 1980 to 2010. Clinical and pathologic variables recorded included age at presentation, recurrence, associated urologic anomalies, incidence of ureteral fusion with mesonephric ductal structures, glomerular filtration rate and urodynamic parameters. RESULTS: Twenty-six patients were identified with documented episodes of epididymitis. Renal injury was noted in five patients (19%), all of whom were diagnosed with neurogenic bladder (NGB) several years after anorectoplasty. NGB was found in ten patients (38%) in our series. Ectopic insertion of ureter into a mesonephric ductal structure was discovered in five patients (19%). Twelve patients (46%) had recurrent episodes of epididymitis, with seven of these patients (58%) being diagnosed with NGB. Two patients in the pubertal group presented with a history of epididymitis and complained of ejaculatory pain. CONCLUSION: Epididymitis in a patient with ARM warrants a comprehensive urologic investigation, particularly in recurrent episodes. Attempts at surgical intervention (e.g. vasectomy) should be avoided until functional assessment of the urinary tract has occurred. Failure to recognize this association may lead to potentially avoidable complications and morbidity. Long term urological follow up of these patients is warranted to identify at risk patients and minimize renal deterioration.

RESUMO

INTRODUCTION: In obstructive azoospermia, choosing a sperm retrieval method for intracytoplasmic sperm injection (ICSI) depends on the preference and expertise of both the urologist and the reproductive endocrinologist. Generally, a percutaneous epididymal sperm aspiration (PESA) is attempted first. Not uncommonly, multiple PESA's are necessary. This study utilizes a rat model to provide an understanding of sperm parameter and histological changes resulting from repetitive PESA procedures. MATERIALS AND METHODS: A cohort of 30 male Wistar rats of reproductive age (68-73 days) was divided into three groups of 10 (G1-G3). All three groups underwent a left epididymal head PESA using a 253/8 gauge needle. The untouched right epididymis acted as the control. At 14 day intervals, G2 and G3 underwent a second and third PESA respectively. Fourteen days after the final PESA, both epididymides and a 1 cm segment of both vas deferentia were harvested for sperm and histological evaluations. RESULTS: The percentage of vas specimens with a sperm count ≥ 5 x104/cc was 100%, 22%, and 20% for the G1, G2, G3 PESA samples respectively. Moreover, the percentage of the vas specimens with sperm motility ≥ 10% was 90%, 22%, and 20%, respectively. Epididymal granulomas were not seen in the control side, but formed in 70%, 100%, and 80% of G1, G2, G3 PESA specimens, respectively. CONCLUSIONS: In a rat model, PESA resulted in significant epididymal inflammation and a reduction in both sperm concentration and motility.
