RESUMO

This guideline offers recommendations on the diagnosis, treatment and health promotion principles needed for the effective management of human papillomavirus (HPV)-related warts at anogenital sites including the external genitals, vagina, cervix, urethra, perianus and anal canal. The guideline is aimed primarily at patients aged 16 years or older presenting to healthcare professionals working in level 3 sexual health services in the United Kingdom. However, the principles of the recommendations may be applied in other care settings, including in primary care, using locally adapted care pathways where appropriate. The management of HPV-related anogenital dysplasia or warts at other extragenital sites is outside the scope of this guideline.

RESUMO

Children, adolescents and young adults with testicular germ cell tumors require appropriate surgical care to insure excellent outcomes. This article presents the most critical elements, and their basis in evidence, for surgery in this population. Specifically, the importance of inguinal radical orchiectomy for malignant tumors, partial orchiectomy for prepubertal tumors and normal serum tumor markers, and the appropriate use of post-chemotherapy retroperitoneal lymph node dissection in those with residual retroperitoneal masses.

RESUMO

BACKGROUND: Lymphovascular invasion (LVI) has been identified as a poor prognostic factor for a variety of tumors; however, its significance in malignant ovarian germ cell tumors (MOGCT) in pediatric and adolescent patients is not well described. We aim to clarify the significance of LVI in the subset of patients with nongerminomatous MOGCT. METHODS: Records of patients 0-20 years of age with MOGCT enrolled on Children's Oncology Group study AGCT0132 were reviewed. Patients with documented presence or absence of LVI in either institutional or central review pathology reports were included. RESULTS: Of 130 patients with MOGCTs, 83 patients had of the presence or absence of LVI documented in their pathology report. 42/83 patients (50.6%) were found to have LVI present. The estimated odds of having LVI was higher in patients with stage II and III disease, 11 years and older and with the presence of choriocarcinoma. Event-free survival (EFS) and overall survival (OS) remained high in patients with LVI. Approximately 50% of patients with a documented LVI status in either institutional pathology report or central review were found to have LVI. CONCLUSIONS: The presence of LVI was higher in tumors with adverse risk factors including higher stage and age greater than 11 years. While LVI was not associated with EFS or OS in the intermediate risk group, further work is necessary to determine the effect of LVI on long-term disease-free survival. We, therefore, recommend routinely incorporating LVI status into institutional pathology reports for pediatric and adolescent patients with MOGCT. LEVEL OF EVIDENCE: III.

RESUMO

BACKGROUND: Bacterial vaginosis is a common and distressing condition for women. Short-term antibiotic treatment is usually clinically effective, but recurrence is common. We assessed the effectiveness of intravaginal lactic acid gel versus oral metronidazole for treating recurrent bacterial vaginosis. METHODS: We undertook an open-label, multicentre, parallel group, randomised controlled trial in nineteen UK sexual health clinics and a university health centre. Women aged ≥ 16 years, with current bacterial vaginosis symptoms and a preceding history of bacterial vaginosis, were randomised in a 1:1 ratio using a web-based minimisation algorithm, to 400 mg twice daily oral metronidazole tablets or 5 ml once daily intravaginal lactic acid gel, for 7 days. Masking of participants was not possible. The primary outcome was participant-reported resolution of symptoms within 2 weeks. Secondary outcomes included time to first recurrence of symptoms, number of recurrences and repeat treatments over 6 months and side effects. RESULTS: Five hundred and eighteen participants were randomised before the trial was advised to stop recruiting by the Data Monitoring Committee. Primary outcome data were available for 79% (204/259) allocated to metronidazole and 79% (205/259) allocated to lactic acid gel. Resolution of bacterial vaginosis symptoms within 2 weeks was reported in 70% (143/204) receiving metronidazole versus 47% (97/205) receiving lactic acid gel (adjusted risk difference -23·2%; 95% confidence interval -32.3 to -14·0%). In those participants who had initial resolution and for whom 6 month data were available, 51 of 72 (71%) women in the metronidazole group and 32 of 46 women (70%) in the lactic acid gel group had recurrence of symptoms, with median times to first recurrence of 92 and 126 days, respectively. Reported side effects were more common following metronidazole than lactic acid gel (nausea 32% vs. 8%; taste changes 18% vs. 1%; diarrhoea 20% vs. 6%, respectively). CONCLUSIONS: Metronidazole was more effective than lactic acid gel for short-term resolution of bacterial vaginosis symptoms, but recurrence is common following both treatments. Lactic acid gel was associated with fewer reported side effects. TRIAL REGISTRATION: ISRCTN14161293 , prospectively registered on 18th September 2017.

RESUMO

Background: Over the past decade, there has been increased utilization of medical cannabis (MC) in the United States. Few studies have described sociodemographic and clinical factors associated with MC use after certification and more specifically, factors associated with use of MC products with different cannabinoid profiles. Methods: We conducted a longitudinal cohort study of adults (N=225) with chronic or severe pain on opioids who were newly certified for MC in New York State and enrolled in the study between November 2018 and January 2022. We collected data over participants' first 3 months in the study, from web-based assessment of MC use every 2 weeks (unit of analysis). We used generalized estimating equation models to examine associations of sociodemographic and clinical factors with (1) MC use (vs. no MC use) and (2) use of MC products with different cannabinoid profiles. Results: On average, 29% of the participants used predominantly high delta-9-tetrahydrocannabinol (THC) MC products within the first 3 months of follow-up, 30% used other MC products, and 41% did not use MC products. Non-Hispanic White race, pain at multiple sites, and past 30-day sedative use were associated with a higher likelihood of MC use (vs. no MC use). Current tobacco use, unregulated cannabis use, and enrollment in the study during the COVID-19 pandemic were associated with a lower likelihood of MC use (vs. no MC use). Among participants reporting MC use, female gender and older age were associated with a lower likelihood of using predominantly high-THC MC products (vs. other MC products). Conclusion: White individuals were more likely to use MC after certification, which may be owing to access and cost issues. The findings that sedative use was associated with greater MC use, but tobacco and unregulated cannabis were associated with less MC use, may imply synergism and substitution that warrant further research. From the policy perspective, additional measures are needed to ensure equitable availability of and access to MC. Health practitioners should check patients' history and current use of sedative, tobacco, and unregulated cannabis before providing an MC recommendation and counsel patients on safe cannabis use. clinicaltrials.gov (NCT03268551).

RESUMO

Despite improved clinical outcomes of initiating antiretroviral therapy (ART) soon after diagnosis, conflicting evidence exists regarding the impact of same-day ART initiation on subsequent clinical outcomes. We aimed to characterize the associations of time to ART initiation with loss to care and viral suppression in a cohort of newly diagnosed people living with HIV (PLHIV) entering care after Rwanda implemented a national "Treat All" policy. We conducted a secondary analysis of routinely collected data of adult PLHIV enrolling in HIV care at 10 health facilities in Kigali, Rwanda. Time from enrollment to ART initiation was categorized as same day, 1-7 days, or >7 days. We examined associations between time to ART and loss to care (>120 days since last health facility visit) using Cox proportional hazards models, and between time to ART and viral suppression using logistic regression. Of 2,524 patients included in this analysis, 1,452 (57.5%) were women and the median age was 32 (interquartile range: 26-39). Loss to care was more frequent among patients who initiated ART on the same day (15.9%), compared with those initiating ART 1-7 days (12.3%) or >7 days (10.1%), p < .001. In multivariable analyses, same-day ART initiation was associated with a greater hazard of loss to care compared with initiating >7 days after enrollment (adjusted hazard ratio 1.39, 95% confidence interval: 1.04-1.85). A total of 1,698 (67.3%) had available data on viral load measured within 455 days after enrollment. Of these, 1,476 (87%) were virally suppressed. A higher proportion of patients initiating ART on the same day were virally suppressed (89%) compared with those initiating 1-7 days (84%) or >7 days (88%) after enrollment. This association was not statistically significant. Our findings suggest that ensuring adequate, early support for PLHIV initiating ART rapidly may be important to improve retention in care for newly diagnosed PLHIV in the era of Treat All.

RESUMO

BACKGROUND: While microbiome and host regulation contribute independently to many disease states, it is unclear how circumcision in pediatric population influences subsequent changes in penile microbiome. OBJECTIVE: Our study aims to analyze jointly paired taxonomic profiles and assess pathways implicated in inflammation, barrier protection, and energy metabolism. DESIGN, SETTING, AND PARTICIPANTS: We analyzed 11 paired samples, periurethral collection, before and after circumcision, to generate microbiome and mycobiome profiling. Sample preparation of 16S ribosomal RNA and internal transcribed spacer sequencing was adapted from the methods developed by the National Institutes of Health Human Microbiome Project. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We obtained the predictive functional attributes of the microbial communities between samples using Silva-Tax4Fun and the Greengenes-Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) approach. The predictive functioning of the microbial communities was determined by linearly combining the normalized taxonomic abundances into the precomputed association matrix of Kyoto Encyclopedia of Genes and Genomes orthology reference profiles. RESULTS AND LIMITATIONS: Several notable microbiome and mycobiome compositional differences were observed between pre- and postcircumcision patients. Pairwise comparisons across taxa revealed a significant decrease (p < 0.05, false discovery rate corrected) of microbiome organisms (Clostridiales, Bacteroidales, and Campylobacterales) and mycobiome (Saccharomycetales and Pleosporales) following circumcision. A total of 14 pathways were found to differ in abundance between the pre- and postcircumcision groups (p < 0.005, false discovery rate <0.1 and linear discriminant analysis score >3; five enriched and nine depleted). The pathways reduced after circumcision were mostly involved with amino acid and glucose metabolism, while pathways prior to circumcision were enriched in genetic information processing and transcription processes. As expected, enrichment in methyl-accepting chemotaxis protein, an integral membrane protein involved in directed motility of microbes to chemical cues and environment, occurred prior to circumcision, while the filamentous hemagglutinin pathway (a strong immunogenic protein) was depleted after circumcision CONCLUSIONS: Our results offer greater insight into the host-microbiota relationship of penile circumcision and may serve to lay the groundwork for future studies focused on drivers of inflammation, infection, and oncogenesis. PATIENT SUMMARY: Our study showed a significant reduction in bacteria and fungi after circumcision, particularly anaerobic bacteria, which are known to be potential inducers of inflammation and cancer. This is the first study of its kind showing the changes in microbiome after circumcision, and some of the changes that occur in healthy infants after circumcision that may explain the differences in cancer and inflammatory disorders in adulthood.

RESUMO

BACKGROUND: Treat-All guidelines recommend initiation of antiretroviral therapy (ART) for all people with HIV (PWH) on the day of diagnosis when possible, yet uncertainty exists about the impact of same-day ART initiation on subsequent care engagement. We examined the association of same-day ART initiation with loss to follow-up and viral suppression among patients in 11 sub-Saharan African countries. METHODS: We included ART-naive adult PWH from sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium who enrolled in care after Treat-All implementation and prior to January 2019. We used multivariable Cox regression to estimate the association between same-day ART initiation and loss to follow-up and Poisson regression to estimate the association between same-day ART initiation and 6-month viral suppression. RESULTS: Among 29 017 patients from 63 sites, 18 584 (64.0%) initiated ART on the day of enrollment. Same-day ART initiation was less likely among those with advanced HIV disease versus early-stage disease. Loss to follow-up was significantly lower among those initiating ART ≥1 day of enrollment, compared with same-day ART initiators (20.6% vs 27.7%; adjusted hazard ratio: .66; 95% CI .57-.76). No difference in viral suppression was observed by time to ART initiation (adjusted rate ratio: 1.00; 95% CI: .98-1.02). CONCLUSIONS: Patients initiating ART on the day of enrollment were more frequently lost to follow-up than those initiating later but were equally likely to be virally suppressed. Our findings support recent World Health Organization recommendations for providing tailored counseling and support to patients who accept an offer of same-day ART.

RESUMO

BACKGROUND: The UK National Chlamydia Screening Programme uses an opportunistic approach. Many programmes use campaigns to raise awareness of chlamydia screening in young people. This review aimed to assess the effectiveness of campaigns on uptake of chlamydia screening in young people. METHODS: We conducted a mixed-methods systematic review of articles assessing the outcomes of community-based health-promotion campaigns to increase chlamydia screening in young people, their experiences of the campaigns and other facilitators and barriers to the conduct of the campaigns. We searched four databases for quantitative and qualitative studies with no language restrictions. MAIN RESULTS: From 10 329 records identified, 19 studies (20 articles) were included in the review: 14 quantitative, 2 qualitative and 3 mixed methods. All studies with quantitative outcomes were before-after study designs or interrupted time series. The prediction interval for relative change (RC) in test counts ranged from 0.95 to 1.56, with a summary pooled estimate of RC 1.22 (95% CI 1.14 to 1.30, 13 studies, I2=97%). For test positivity rate, 95% prediction interval was 0.59 to 1.48, with a summary pooled estimate of RC 0.93 (95% CI 0.81 to 1.07, 8 studies, I2=91.8%). Large variation in characteristics between studies precluded exploring outcomes by type of campaign components. Seven major qualitative themes to improve screening were identified: targeting of campaigns; quality of materials and message; language; anonymity; use of technology; relevance; and variety of testing options. CONCLUSIONS: Health promotion campaigns aiming to increase chlamydia testing in those aged 15-24 years may show some effectiveness in increasing overall numbers of tests, however numbers of positive tests do not follow the same trend. Qualitative findings indicate that campaigns require clear, relevant messaging that displays the full range of testing options and assures anonymity in order to be effective.

RESUMO

STUDY OBJECTIVE: Pediatric ovarian neoplasms with imaging appearance suggestive of teratoma are often presumed to have low risk of malignancy. We assessed the pre-operative imaging appearance of pediatric malignant ovarian germ cell tumors (MOGCT) and the presence of associated teratoma in a series of MOGCT. DESIGN: Retrospective review of clinical and pathology data. SETTING: Multicenter trial for extracranial malignant germ cell tumors in young female individuals by the Children's Oncology Group (COG study AGCT0132) that included yolk sac tumor, embryonal carcinoma and choriocarcinoma. PARTICIPANTS: Female individuals 0-20 years of age at enrollment with ovarian primary nonseminomatous malignant germ cell tumors. INTERVENTIONS: Review of data forms, including prospectively collected surgical checklist documenting imaging characteristics of the tumor, and review of pathology reports. MAIN OUTCOME MEASURES: Description of imaging appearance and frequency of mixed histology with benign teratoma elements. RESULTS: A total of 138 female individuals (11 months to 20 years of age) had primary ovarian tumors. Imaging appearance and pathology information were available for 133 patients. Among the 133 patients, tumor appearance was solid (10.5%), solid with calcification (3.0%), mixed cystic and solid (58.7%), mixed cystic and solid with calcification (24.8%), and unknown (3.0%). In all, 54% had elements of teratoma in addition to malignant histology. CONCLUSION: Mixed cystic and solid appearance with or without calcification was seen in 83.5% of pediatric ovarian malignant germ cell tumors. Associated benign teratoma was common. The presence of a mixed cystic and solid appearance on preoperative imaging should not dissuade the surgeon from obtaining preoperative serum markers and undertaking complete surgical staging.

RESUMO

While radical orchiectomy remains the gold standard for testicular cancer, partial orchiectomy has become a well-accepted organ-sparing approach for benign testicular tumors in pre-pubertal patients. The aims of testicular-sparing surgery include prevention of over-treatment, preservation of future hormonal and reproductive function, and provision of a durable cure. For pre-pubertal patients, who have a high likelihood of benign lesions, partial orchiectomy provides effective treatment, owing to the high reliability of scrotal ultrasound (US) and intraoperative frozen section. In adolescent and young adult patients, who are more likely to harbor malignant pathology, the role of partial orchiectomy is less clear. Testis-sparing surgery is being reported with greater frequency in the adult literature for small testicular masses and for situations in which radical orchiectomy would result in an anorchia. More recently, a testis-sparing approach has also been described for carefully-selected post-pubertal pediatric patients. This review will highlight the role of partial orchiectomy in pediatric patients (<18 years old).

RESUMO

Rhabdomyolysis, the release of myoglobin and other cellular breakdown products from necrotic muscle tissue, is seen in patients with crush injuries, drug overdose, malignant hyperthermia, muscular dystrophy, and with increasing frequency in obese patients undergoing routine procedures. For the perioperative clinician, managing the resultant shock, hyperkalemia, acidosis, and myoglobinuric acute kidney injury can present a significant challenge. Prompt recognition, hydration, and correction of metabolic disturbances may reduce or eliminate the need for long-term renal replacement therapy. This article reviews the pathophysiology and discusses key issues in the perioperative diagnosis, risk stratification, and management of rhabdomyolysis.

RESUMO

In the United States, undocumented African immigrants living with HIV enter care late, potentially leading to adverse individual and population health outcomes, yet little is known about the specific experiences of HIV diagnosis and linkage to care among this population. We conducted individual, semi-structured interviews with adults who were undocumented African immigrants living with HIV in New York City. Interviews explored perspectives regarding individual, social, institutional, and societal barriers and facilitators of HIV testing and linkage to care. Of 14 participants from 9 different African countries, 9 were women and the median age was 44 years (interquartile range: 42-50). Participants described fear of discovery by immigration authorities as a substantial barrier to HIV testing and linking to initial medical appointments. Actual and perceived structural barriers to both testing and care linkage included difficulty obtaining health insurance and a belief that undocumented immigrants are ineligible for any health services. Participants also expressed reluctance to be tested because of HIV-related stigma within the immigrant communities that they heavily relied on. After diagnosis, however, participants overwhelmingly described a positive role of health and social service providers in facilitating linkage to HIV care. Concerns about immigration status and HIV-related stigma are significant barriers to HIV testing and linkage to care among undocumented African immigrants. Multilevel efforts to reduce stigma and increase awareness of available services could enhance rates of HIV testing and care linkage in this population.

RESUMO

PURPOSE: In this report, we characterize the timing and behavior of malignant ovarian germ cell tumors (GCTs) in pediatric patients with dysgenetic gonads compared to those with normal gonadal development. PATIENTS AND METHODS: Patients from the Children's Oncology Group AGCT0132 with malignant ovarian GCTs were included. Within this population, we sought to identify patients with gonadoblastoma, streak ovaries, or other evidence of gonadal dysgenesis (GD). Patients with malignant GCTs containing one or more of the following histologies-yolk sac tumor, embryonal carcinoma, or choriocarcinoma-were included. Patients were compared with respect to event-free survival (EFS) and overall survival (OS). RESULTS: Nine patients with GD, including seven with gonadoblastoma (mean age, 9.3 years), were compared to 100 non-GD patients (mean age, 12.1 years). The estimated 3-year EFS for patients with GD was 66.7% (95% CI 28.2-87.8%) and for non-GD patients was 88.8% (95% CI 80.2-93.8%). The estimated 3-year OS for patients with GD was 87.5% (95% CI 38.7-98.1%) and for non-GD patients was 97.6% (95% CI of 90.6-99.4%). CONCLUSION: Patients presenting with nongerminomatous malignant ovarian GCTs in the context of GD have a higher rate of events and death than counterparts with normal gonads. These findings emphasize the importance of noting a contralateral streak ovary or gonadoblastoma at histology for any ovarian GCT and support the recommendation for early bilateral gonadectomy in patients known to have GD with Y chromosome material. In contrast to those with pure dysgerminoma, these patients may represent a high-risk group that requires a more aggressive chemotherapy regimen.

RESUMO

Purpose To investigate whether event-free survival (EFS) can be maintained among children and adolescents with intermediate-risk (IR) malignant germ cell tumors (MGCT) if the administration of cisplatin, etoposide, and bleomycin (PEb) is reduced from four to three cycles and compressed from 5 to 3 days per cycle. Patients and Methods In a phase 3, single-arm trial, patients with IR MGCT (stage II-IV testicular, II-III ovarian, I-II extragonadal, or stage I gonadal tumors with subsequent recurrence) received three cycles of PEb. A parametric comparator model specified that the observed EFS rate should not be significantly < 92%. As recommended for trials that test a reduction of therapy, a one-sided P value ≤ .10 was used to indicate statistical significance. In a post hoc analysis, we also compared results to the EFS rate of comparable patients treated with four cycles of PEb in two prior studies. Results Among 210 eligible patients enrolled from 2003 to 2011, 4-year EFS (EFS4) rate was 89% (95% confidence interval, 83% to 92%), which was significantly lower than the 92% threshold of the comparison model ( P = .08). Among 181 newly diagnosed patients, the EFS4 rate was 87%, compared with 92% for 92 comparable children in the historical cohort ( P = .15). The EFS4 rate was significantly associated with stage (stage I, 100%; stage II, 92%; stage III, 85%; and stage IV, 54%; P < .001). Conclusion The EFS rate for children with IR MGCT observed after three cycles of PEb was less than that of a prespecified parametric model, particularly for patients with higher-stage tumors. These data do not support a reduction in the number of cycles of PEb from four to three. However, further investigation of a reduction in the number of cycles for patients with lower-stage tumors is warranted.

RESUMO

PURPOSE: Objective data on patterns of oncology practice among pediatric urologists are lacking. We reviewed surgical case logs submitted to the American Board of Urology by those self-reporting as pediatric urologists. We hypothesized that logs would reveal a low oncology volume (fewer than 5 cases) and identify orchiectomy as the most common oncology cases, and that less than 25% of logs would show nephrectomy for renal tumor. MATERIALS AND METHODS: Case logs submitted for American Board of Urology certification, recertification or pediatric subspecialty certification were reviewed and standardized to represent 12-month practice. Data were collected on pediatric oncologic surgeries as noted by procedure codes linked with oncologic diagnosis codes for patients up to age 30 years. RESULTS: We identified 281 case logs meeting study criteria. A total of 364 oncology cases were logged and 131 logs (46.6%) listed at least 1 oncology case, while 150 (53.4%) contained no oncology cases. The 75th, 90th and 95th percentiles of oncology volume were represented by reporting 2, 3 and 4 cases, respectively. A total of 13 logs (4.6%) accounted for more than a third of all oncology cases (35.9%). The most frequent oncology case logged was orchiectomy, which was documented in 83 logs (29.5%). On Poisson regression surgeon variables associated with higher oncology volume included male gender (IRR 2.8, 95% CI 2.1-3.9), 2010 log year (IRR 2.4, 95% CI 1.3-4.4), 2015 log year (IRR 3.7, 95% CI 2.1-6.4) and nonpediatric subspecialty certification log (IRR 1.6, 95% CI 1.2-2.3). CONCLUSIONS: Few pediatric urologists perform a high volume of oncologic surgeries based on surgical case logs submitted to the American Board of Urology. A small cohort of pediatric urologists logged the majority of such cases.

RESUMO

PURPOSE: Data are lacking on the current perception of oncology care among pediatric urologists. Thus, we developed, pilot tested and administered a survey on this topic to SPU (Society for Pediatric Urology) members. MATERIALS AND METHODS: Approval for this proposal was granted by SPU leadership prior to developing or distributing the survey instrument. The survey was developed and pilot tested by the PUOWG (Pediatric Urologic Oncology Working Group). Response data were collected and descriptive statistics were used for analysis. Logistic regression analysis was performed to correlate surgeon reported factors with higher volumes of reported oncology surgery. RESULTS: A total of 426 surveys were distributed via email to SPU members and 212 individual surveys (49.8%) were returned with the background/introduction section completed. Of these surveys 200 (94.3%) were completed by practicing pediatric urologists. Overall, 155 respondents (77.5%) reported performing 5 or fewer oncology related surgeries per year and 74.9% reported that less than 25% of renal tumor surgery at their institution was performed through the pediatric urology service. On multivariate analysis the self-reported factors significantly associated with increased oncology surgical volume (more than 5 cases per year) were greater than 50% attendance at institutional tumor board meetings (OR 4.8, 95% CI 1.4-16.9) and practicing at a hospital with a higher volume of renal tumor surgery (OR 2.6, 95% CI 1.2-5.8). CONCLUSIONS: Few surveyed pediatric urologists reported performing a high volume of oncology surgery. Respondents expressed interest in ways to increase pediatric urology involvement in oncology care, including opportunities for increased education. Self-reported factors that correlated with higher volume were regular attendance at the institutional pediatric tumor board and practice at a higher volume institution.

RESUMO

At most institutions, pediatric urologists play a limited role in the care of children with cancer. Pediatric urologists have a unique experience and skill set to contribute to the care of these patients. Interested pediatric urologists should become experts in pediatric urologic oncology and demonstrate this interest by participating in tumor board and relevant academic activities. They should advocate for a collaborative approach with pediatric general surgeons in the surgical management of children with genitourinary as such an approach benefits patient care, contributes to professional development of all parties, and develops relationships that contribute to programmatic development for the institution in oncology and other areas.

RESUMO

Organ-sparing approaches have been applied to the treatment of a variety of urologic tumors in both the realms of adult and pediatric urology, with the goals of minimizing overtreatment of benign lesions, preserving function, and providing durable cure. The predominance of benign tumors in prepubertal patients and the reliability of both ultrasound and intraoperative frozen sections have resulted in a marked shift toward testis-sparing approaches over the last few decades. The role of testis sparing in the adolescent population is presently unclear, although there have been increasing reports of successful organ-sparing surgery for testis tumors in the adult literature. This review presents recent trends in testis-sparing approaches for both pediatric and adolescent patients, the operative technique, and some of the controversies related to testis-sparing surgery.
