ABSTRACT Objective To report the effects of a tunica vagina flap on testicular compartment syndrome. Methods This single-arm clinical trial was conducted from September 2020 to October 2021. Consecutive patients with suspected testicular torsion within 24 hours of pain onset were included. Patients with past testicular torsion, bilateral torsion, or previous atrophy were excluded. The tunica vaginalis was opened, and the intratesticular pressure was measured before testicular retrieval from the scrotum and detorsion (P1), after detorsion (P2), and after transverse incision (P3). A tunica vaginalis flap was performed and a new intratesticular pressure was recorded (P4). The contralateral testicular pressure was recorded before fixation (Pc). The minimum follow-up period was 6 months. Results Fifteen patients were recruited from September 2020 to October 2021. Nine patients completed the follow-up. The median age (range) was 15 years (9-19). The mean P1, P2, P3, P4, and Pc (range) were 43, 60, 23, 20, and 14mmHg, respectively. The atrophy rate was 66.3% and the viability was 88.9%. No major complications were observed. Conclusion The modified tunica vaginalis flap in acute testicular torsion decreased intratesticular pressure. Furthermore, normal testicular pressure can improve testicular preservation. It can also decrease testicular pressure to normal levels and preserve the testicular parenchyma.

ABSTRACT Objective To evaluate the time interval and possible delay in transportation to referral units for the treatment of testicular torsion. Methods We retrospectively analyzed all cases of spermatic cord torsion surgically treated at a university hospital between January 2018 to December 2021. We evaluated the time intervals, including pain onset until the first presentation (D1), interhospital transference time (D2), pain onset until urological evaluation in a tertiary service (D3), urological evaluation until surgery (D4), and time from pain onset to surgical treatment (D5). We analyzed demographic and surgical data, orchiectomy rates, and time intervals (D1–D5). Torsions presented to the first medical presentation within 6h were considered early for testicular preservation. Results Of the 116 medical records evaluated, 87 had complete data for the time interval analysis (D1 to D5) and were considered the total sample. Thirty-three had D1 ≤6h, 53 had D1 ≤24h (includes patients in the D1 ≤6h subgroup), and 34 had D1 >24h. The median time intervals of the total samples and subgroups D1 ≤6h, D1 ≤24h, and D1 >24h were D1 = 16h 42min, 2h 43min, 4h 14min and 72h, D2 = 4h 41min, 3h 39min, 3h 44min and 9h 59min; D3 = 24h, 6h 40min, 7h and 96h; D4 = 2h 20min, 1h 43min, 1h 52min and 3h 44min; D5 = 24h 42min, 8h 03min, 9h 26min and 99h 10min, respectively. Orchiectomy rates of the total sample, subgroups D1 ≤6h, D1 ≤24h, and D1 >24h were 56.32%, 24.24% (p

ABSTRACT Objective To understand the feasibility of FGFR3 tests in the Brazilian public health context, and to sample the mutational burden of this receptor in high-grade muscle invasive bladder cancer. Methods A total of 31 patients with high-grade muscle-invasive bladder cancer were included in the present study. Either transurethral resection of bladder tumor or radical cystectomy specimens were analyzed. Formalin-fixed paraffin-embedded tissue blocks were sectioned, hematoxylin and eosin stained, and histologic sections were reviewed. Total RNA was extracted using the RNeasy DSP formalin-fixed paraffin-embedded kit. Qualitative results were displayed in Rotor-Gene AssayManager software. Results Six patients were excluded. From the samples analyzed, four (16.7%) were considered inadequate and could not have their RNA extracted. Two patients presented FGFR3 mutations, accounting for 9.5% of material available for adequate analysis. The two mutations detected included a Y373C mutation in a male patient and a S249C mutation in a female patient. Conclusion FGFR3 mutations could be analyzed in 84% of our cohort and occurred in 9.5% of patients with high-grade muscle invasive bladder cancer in this Brazilian population. FGFR3 gene mutations are targets for therapeutic drugs in muscle-invasive bladder cancer. For this reason, know the frequency of these mutations can have a significant impact on public health policies and costs provisioning.

ABSTRACT Objective: To evaluate awareness of prostate cancer in the population of the city of São Paulo. Methods: A total of 392 adults were randomly interviewed on public spaces in the city of São Paulo, and answered a questionnaire that addressed demographic questions and specific knowledge about the prostate cancer. A score was used to assess awareness of cancer in general, and of prostate cancer, considering satisfactory knowledge a score of 6 points. Results: The mean age was 36.9 years (standard deviation of ±12.6) and 58.2% of participants were male. No previous contact with information related to prostate cancer was reported by 45.5% of participants. For these cases, a greater proportion was observed among men aged over 50 years. As to the score, the mean was 3.7 (standard deviation of ±1.3), with a positive correlation among higher scores, higher income and education level. Less than 5% of participants believed they should only search for prostate cancer screening when symptomatic. Finally, among the less frequent responses to risk factors for prostate cancer, is “ethnic origin” (2.8%). Conclusion: Even though most participants did not have a satisfactory score, the level of awareness demonstrated in this study seems superior to that of other populational series. Hence it suggested the assessed population understood some essential concepts in prostate cancer, such as the importance of screening and the follow-up. The efforts made by the Sociedade Brasileira de Urologia on educational campaigns partially explain this. However, working in some concepts, like identifying risk factors for prostate cancer, might optimize screening outcomes.

ABSTRACT Objective: To analyze the association between climate changes in the macroregions in the state of São Paulo and testicular torsion treated cases. Methods: The cases were selected in the Brazilian Public Health Data System Database from January 2008 to November 2016. All surgical procedure records were identified by the Hospital Admission Authorization document. Two codes were selected to process the search: testicular torsion (surgical cure code) and acute scrotum (exploratory scrototomy code). The macroregions were grouped in five areas linked to climate characteristics by International Köppen Climate Classification. Results: A total of 2,351 cases of testicular torsion were registered in the period. For the areas B, C and E (testicular torsion n=2,130) there were statistical differences found in association of testicular torsion cases and decreased temperature (p=0.019, p=0.001 and p=0.006, respectively), however, in analyses for the areas A and D statistical differences were not observed (p=0.066 and p=0.494). Conclusion: Decrease in temperature was associated with testicular torsion in three macroregions of São Paulo. The findings support the theory of cold weather like a trigger in occurrence of testicular torsion in a tropical climate region.

ABSTRACT Objective: To analyze mortality rates and hospitalization data after radical cystectomy in each public healthcare center in São Paulo in the last decade, considering the number of surgeries performed at each center. Methods: This study included patients from the Departamento de Informática do Sistema Único de Saúde from the state of São Paulo, who underwent radical cystectomy between 2008 and 2018. Data analyzed included organization name, number of procedures/year, in-hospital death rates and hospital length of stay. Results: A total of 1,377 radical cystectomies were registered in the public health system in São Paulo, between 2008-2018. A total of 91 institutions performed at least one radical cystectomy in the decade analyzed. The number of radical cystectomies performed per organization during the years analyzed ranged from one to 161. Only 45.6% of patients were operated in organizations that performed more than five radical cystectomies yearly. A total of 684 patients were operated in organizations with higher surgical volume. There were 117 in-hospital deaths, representing an 8.5% mortality rate for the state of São Paulo during the last decade. Whereas highest volume organizations (>6 radical cystectomies/year) had a mortality rate of 6.1%, the lowest volume (

ABSTRACT Objective: To gather information on penile cancer epidemiologic trends and its economic impact on the Brazilian Public Health System across the last 25 years. Methods: The Brazilian Public Health System database was used as the primary source of data from January 1992 to December 2017. Mortality and incidence data from the Instituto Nacional de Câncer José Alencar Gomes da Silva was collected using the International Classification of Diseases ICD10 C60. Demographic data from the Brazilian population was obtained from the last census by the Brazilian Institute of Geography and Statistics, performed in 2010 and its 2017 review. Results: There were 9,743 hospital admissions related to penile cancer from 1992 to 2017. There was a reduction (36%) in the absolute number of admissions per year related to penile cancer in 2017, as compared to 1992 (2.7versus 1.7 per 100,000; p

ABSTRACT Objective: To evaluate sperm concentration, morphology and motility of Brazilian semen donors from 1992 to 2003, in the city of São Paulo. Methods: Retrospective study analyzing 182 donor semen samples from 1992 to 2003. The first and the second donated sample were analyzed for each donor. Donor average age was 30.8 years. Means with standard errors, medians with minimum and maximum values, and interquartile ranges were calculated for age, sperm concentration, semen volume, oval morphology and motility. The relation between each characteristic of the semen samples and the year of donation, as well as donor age and season of the year were studied by linear and multiple regression analysis. Results: Linear regression analysis showed that the sperm concentration (R2 = 19.1%, R2 = 20.2%, p < 0.0001 respectively) and the oval morphology (R2 = 13%; R2 = 13.5%; p < 0.0001, respectively) decreased significantly, even when the first or the second sperm collection is considered. The ejaculated volume showed slight increase during the period for both samples (R2 = 2.2%, p = 0.048; R-sq = 2.4%. p = 0.038, respectively). All characteristics did not depend on the donors’ age or season of the year when the samples were obtained. Conclusions: There was a decrease in spermatic concentration and percentage of oval sperm of semen donors samples from 1992 to 2003, in the city of São Paulo.

Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as non-obstructive azoospermia, or to the obstruction of the efferent ducts of the genital tract and classified as obstructive azoospermia. Before the development of intracytoplasmic sperm injection, in 1992, men with non-treatable obstructive azoospermia or non-obstructive azoospermia could not become biologic fathers. Intracytoplasmic sperm injection has dramatically changed this scenario, as it allows obtaining an embryo using a single sperm cell. Since then, sperm obtained from different sources have been used for intracytoplasmic sperm injection, and the techniques used for sperm retrieval are microsurgical epididymal sperm aspiration (MESA) or percutaneous epididymal sperm aspiration (PESA) for patients with obstructive azoospermia, and testicular sperm aspiration (TESA), testicular sperm extraction (TESE) or testicular microdissection for non-obstructive azoospermia patients. This article discusses these techniques, and their indications and results.

OBJECTIVES: There is a tendency to adopt prolonged culture inolder patients; however there are no conclusive results about theinfluence of age on blastulation rate. Therefore, we decided to analyzethe influence of female age on prolonged culture results. METHODS:One hundred and seven ICSI procedures performed in our centerfrom January 1999 to December 2000 were retrospectively analyzed.The blastulation rate was verified and correlated with patient age.RESULTS: In average, 2.8 blastocysts/patient were transferred. Theblastulation rate for each age group was: 180 (32%) in the group 40 years. The statistical analysis demonstrated a significantdifference (p < 0.05). CONCLUSION: The percentage of embryosthat achieved the blastocyst stage was different in each age groupand this percentage dropped as patient age increased. Female agemay influence on blastulation rate of pre-embryos, observing a dropin this rate as patient age increased.

ABSTRACT Objective To evaluate the incidence of Y-chromosome microdeletions in individuals born from vasectomized fathers who underwent vasectomy reversal or in vitro fertilization with sperm retrieval by epididymal aspiration (percutaneous epididymal sperm aspiration). Methods A case-control study comprising male children of couples in which the man had been previously vasectomized and chose vasectomy reversal (n=31) or in vitro fertilization with sperm retrieval by percutaneous epididymal sperm aspiration (n=30) to conceive new children, and a Control Group of male children of fertile men who had programmed vasectomies (n=60). Y-chromosome microdeletions research was performed by polymerase chain reaction on fathers and children, evaluating 20 regions of the chromosome. Results The results showed no Y-chromosome microdeletions in any of the studied subjects. The incidence of Y-chromosome microdeletions in individuals born from vasectomized fathers who underwent vasectomy reversal or in vitro fertilization with spermatozoa recovered by percutaneous epididymal sperm aspiration did not differ between the groups, and there was no difference between control subjects born from natural pregnancies or population incidence in fertile men. Conclusion We found no association considering microdeletions in the azoospermia factor region of the Y chromosome and assisted reproduction. We also found no correlation between these Y-chromosome microdeletions and vasectomies, which suggests that the assisted reproduction techniques do not increase the incidence of Y-chromosome microdeletions.
