SARS-CoV-2 pandemic and repercussions for male infertility patients: A proposal for the individualized provision of andrological services.

The prolonged lockdown of health facilities providing non-urgent gamete cryopreservation-as currently recommended by many reproductive medicine entities and regulatory authorities due to the SARS-CoV-2 pandemic will be detrimental for subgroups of male infertility patients. We believe the existing recommendations should be promptly modified and propose that the same permissive approach for sperm banking granted for men with cancer is expanded to other groups of vulnerable patients. These groups include infertility patients (eg, azoospermic and cryptozoospermic) undergoing medical or surgical treatment to improve sperm quantity and quality, as well as males of reproductive age affected by inflammatory and systemic auto-immune diseases who are about to start treatment with gonadotoxic drugs or who are under remission. In both scenarios, the "fertility window" may be transitory; postponing diagnostic semen analysis and sperm banking in these men could compromise the prospects of biological parenthood. Moreover, we provide recommendations on how to continue the provision of andrological services in a considered manner and a safe environment. Our opinion is timely and relevant given the fact that fertility services are currently rated as of low priority in most countries.

Bariatric Surgery Impact on Reproductive Hormones, Semen Analysis, and Sperm DNA Fragmentation in Men with Severe Obesity: Prospective Study.

PURPOSE: Growing evidence in the literature suggests that obesity is capable of altering reproductive hormone levels and male fertility. Effects on classic semen parameters and sperm DNA fragmentation (SDF), however, have not been properly established. Additionally, the impact of bariatric surgery (BS) on those parameters is still controversial. MATERIALS AND METHODS: In Phase 1, 42 patients with obesity and 32 fertile controls were submitted to reproductive hormone evaluation, semen analysis, and SDF testing. In Phase 2, patients with obesity were submitted to BS or clinical follow-up and were invited to 6-month revaluation. RESULTS: Phase 1: Men with obesity have higher levels of estradiol, LH, and FSH and lower levels of total testosterone (TT) when compared with eutrophic fertile men. Additionally, they present worse semen parameters, with reduction in ejaculated volume and sperm concentration, worse sperm motility and morphology, and higher SDF. Phase 2: 32 patients returned to revaluation. Eighteen were submitted to BS (group S) and 14 were not submitted to any specific therapeutic regimen (group NS). In group S, TT more than doubled after surgery (294.5 to 604 ng/dL, p < 0.0001). Worsening of sperm concentration and total ejaculated sperm count were also noticed, and 2 patients became azoospermic after BS. SDF, however, improved after the procedure. No changes in the variables studied were observed in non-operated patients. CONCLUSION: In this prospective study, we have found that BS results in improvements in reproductive hormone levels and SDF after 6-month follow-up. Sperm concentration, however, reduced after the procedure.

Ozone decreases sperm quality in systemic lupus erythematosus patients / O ozônio diminui a qualidade do sêmen em pacientes com lúpus eritematoso sistêmico

Abstract Objective To investigate the deleterious effects of air pollutants exposure in the Sao Paulo metropolitan region on semen quality in systemic lupus erythematosus (SLE). Methods A seven-years longitudinal repeated-measures panel study was performed at the Laboratory of Experimental Air Pollution and Rheumatology Division. Two semen samples from 28 post-pubertal SLE patients were analyzed. Daily concentrations of air pollutants exposure: PM10, SO2, NO2, ozone, CO, and meteorological variables were evaluated on 90 days before each semen collection dates using generalized estimating equation models. Results Intravenous cyclophosphamide (IVCYC) and ozone had an association with a decrease in sperm quality of SLE patients. IVCYC was associated with decreases of 64.3 million of spermatozoa/mL (95% CI 39.01–89.65; p = 0.0001) and 149.14 million of spermatozoa/ejaculate (95% CI 81.93–216.38; p = 0.017). With regard to ozone, the most relevant adverse effects were observed from lags 80–88, when the exposure to an interquartile range increase in ozone 9-day moving average concentration led to decreases of 22.9 million of spermatozoa/mL (95% CI 5.8–40.0; p = 0.009) and 70.5 million of spermatozoa/ejaculate (95% CI 12.3–128.7; p = 0.016). Further analysis of 17 patients that never used IVCYC showed association between exposure to ozone (80–88 days) and decrease of 30.0 million of spermatozoa/mL (95% CI 7.0–53.0; p = 0.011) and 79.0 million of spermatozoa/ejaculate (95% CI 2.1–155.9; p = 0.044). Conclusion Ozone and IVCYC had a consistent adverse effect on semen quality of SLE patients during spermatogenesis. Minimizing exposure to air pollution should be taken into account, especially for patients with chronic systemic inflammatory diseases living in large cities.

Resumo Objetivo Investigar os efeitos deletérios da exposição aos poluentes do ar na Região Metropolitana de São Paulo sobre a qualidade do sêmen de pacientes com lúpus eritematoso sistêmico (LES). Métodos Foi feito um estudo longitudinal de painel com medidas repetidas de sete anos no Laboratório de Poluição Atmosférica Experimental e Reumatologia. Foram analisadas duas amostras de sêmen de 28 pacientes com LES pós‐púberes. Foram avaliadas as concentrações diárias de exposição aos poluentes do ar PM10, SO2, NO2, ozônio e CO e variáveis meteorológicas 90 dias antes de cada data de coleta de sêmen com o uso do método de equações de estimativas generalizadas. Resultados A ciclofosfamida intravenosa (CICIV) e o ozônio estiveram associados a uma diminuição na qualidade do sêmen dos pacientes com LES. A CICIV esteve associada a um decréscimo de 64,3 milhões de espermatozoides/mL (IC 95% 39,01‐89,65; p = 0,0001) e 149,14 milhões de espermatozoides/ejaculado (IC 95% 81,93‐216,38; p = 0,017). Em relação ao ozônio, os efeitos adversos mais relevantes foram observados entre os lags (intervalo de tempo) 80 e 88, quando a exposição a uma concentração média de ozônio um intervalo interquartil maior em nove dias móveis levou a um decréscimo de 22,9 milhões de espermatozoides/mL (IC 95% 5,8‐40; p = 0,009) e 70,5 milhões de espermatozoides/ejaculado (IC 95% 12,3‐128,7; p = 0,016). Uma análise mais aprofundada dos 17 pacientes que nunca usaram CICIV mostrou associação entre a exposição ao ozônio (80‐88 dias) e o decréscimo de 30 milhões de espermatozoides/mL (IC 95% 7‐53; p = 0,011) e 79 milhões de espermatozoides/ejaculado (IC 95% 2,1‐155,9; p = 0,044). Conclusão O ozônio e a CICIV tiveram um efeito adverso consistente sobre a qualidade do sêmen de pacientes com LES durante a espermatogênese. Deve‐se considerar a minimização da exposição à poluição do ar, especialmente para pacientes com doenças inflamatórias sistêmicas crônicas que vivem nas grandes cidades.

Male fertility potential alteration in rheumatic diseases: a systematic review

ABSTRACT Background Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial related to particularities of each disease. This review highlights how rheumatic diseases and their management affect testicular function and male fertility. Materials and Methods A systematic review of literature of all published data after 1970 was conducted. Data was collected about fertility abnormalities in male patients with systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis, ankylosing spondylitis, Behçet disease and gout. Two independent researchers carried out the search in online databases. Results A total of 19 articles were included addressing the following diseases: 7 systemic lupus erythematosus, 6 Behçet disease, 4 ankylosing spondylitis, 2 rheumatoid arthritis, 2 dermatomyositis and one gout. Systemic lupus erythematosus clearly affects gonadal function impairing spermatogenesis mainly due to antisperm antibodies and cyclophosphamide therapy. Behçet disease, gout and ankylosing spondylitis patients, including those under anti-TNF therapy in the latter disease, do not seem to have reduced fertility whereas in dermatomyositis, the fertility potential is hampered by disease activity and by alkylating agents. Data regarding rheumatoid arthritis is scarce, gonadal dysfunction observed as consequence of disease activity and antisperm antibodies. Conclusions Reduced fertility potential is not uncommon. Its frequency and severity vary among the different rheumatic diseases. Permanent infertility is rare and often associated with alkylating agent therapy.

The epidemiology and etiology of azoospermia

The misconception that infertility is typically associated with the female is commonly faced in the management of infertile men. It is uncommon for a patient to present for an infertility evaluation with an abnormal semen analysis report before an extensive female partner workup has been performed. Additionally, a man is usually considered fertile based only on seminal parameters without a physical exam. This behavior may lead to a delay in both the exact diagnosis and in possible specific infertility treatment. Moreover, male factor infertility can result from an underlying medical condition that is often treatable but could possibly be life-threatening. The responsibility of male factor in couple's infertility has been exponentially rising in recent years due to a comprehensive evaluation of reproductive male function and improved diagnostic tools. Despite this improvement in diagnosis, azoospermia is always the most challenging topic associated with infertility treatment. Several conditions that interfere with spermatogenesis and reduce sperm production and quality can lead to azoospermia. Azoospermia may also occur because of a reproductive tract obstruction. Optimal management of patients with azoospermia requires a full understanding of the disease etiology. This review will discuss in detail the epidemiology and etiology of azoospermia. A thorough literature survey was performed using the Medline, EMBASE, BIOSIS, and Cochrane databases. We restricted the survey to clinical publications that were relevant to male infertility and azoospermia. Many of the recommendations included are not based on controlled studies.

Splenogonadal fusion and testicular cancer: case report and review of the literature.

A 36 year-old man after tests for assessing male infertility was diagnosed with primary infertility, bilateral cryptorchidism, nonobstructive azoospermia and discontinuous splenogonadal fusion. Carcinoma in situ was found in his left testicle, which was intraabdominal and associated with splenogonadal fusion. To our knowledge, this is the fourth case of splenogonadal fusion associated with testicular cancer reported. One should always bear in mind the possibility of this association for the left cryptorchid testicle.

Preservação da fertilidade em homens jovens com câncer: conceitos atuais e o futuro / Fertility preservation in young men with cancer: current concepts and future

Nos últimos 40 anos, o perfil mundial do câncer vem mudando. Encarado inicialmente como uma doença dos países ricos, nota-se atualmente que a maior parte de seu ônus global provêm de países de poucos recursos ou em desenvolvimento. Nas últimas décadas o câncer se tornou um problema de saúde pública mundial, com estimativas alarmantes para as décadas subseqüentes. No Brasil, as estimativas para o ano de 2012 serão válidastambém para o ano de 2013 e revelam a ocorrência de aproximadamente 518.510 casos novos de câncer,incluindo os casos de pele não melanoma. São esperados um total de 257.870 casos novos para o sexo masculino. A grande questão é que cerca de 10% destes casos serão na faixa etária inferior a 45 anos e 1% abaixo de 20 anos de idade. Embora o tratamento atual do câncer tenha aumentado consideravelmente as taxas de sobrevida em 5 anos de pacientes jovens, ele quase que invariavelmenteestará associado a enorme risco de infertilidade, levando a impacto negativo importante na vida destes jovens homens. Este artigo de revisão aborda os mais atuais conceitos empreservação de fertilidade em homens jovens tratados de câncer, o crescimento deste campo dentro da oncologia e da urologia e o futuro deste tema tão relevante para nossapopulação. Até hoje existe uma importante desconexão entre os guidelines mundiais e a prática médica, quando o assunto é preservação da fertilidade em homens com câncer em idade reprodutiva...

Over the past 40 years, the global profile of cancer is changing. Initially regarded as a disease of the richcountries, it is noted that currently most of its global burden comes from poor or developing countries. In recent decades cancer has become a public health problem worldwide, withalarming estimates for subsequent decades. In Brazil, the estimates for the year 2012 will be valid for the year 2013 and reveals the occurrence of approximately 518,510 new cases of cancer, including cases of non-melanoma skin. Are expected a total of 257,870 new cases for males. The greatthing is that about 10% of these cases are in the age group below 45 years and 1% below 20 years of age. Although the current treatment of cancer has increased considerablysurvival rates at 5 years young patients, it is almost invariably associated with great risk of infertility, leading to significant negative impact in the lives of these young men. This review article discusses the most current concepts in preserving fertility in young men treated for cancer, thegrowth of this field within the oncology and urology and the future of this topic so relevant to our population. Eventoday there is a important disconnect between the world and medical practice guidelines, when it comes to fertility preservation in men with cancer of reproductive age...

Splenogonadal fusion and testicular cancer: case report and review of the literature / Fusão esplenogonadal e câncer testicular: relato de caso e revisão da literatura

A 36 year-old man after tests for assessing male infertility was diagnosed with primary infertility, bilateral cryptorchidism, nonobstructive azoospermia and discontinuous splenogonadal fusion. Carcinoma in situ was found in his left testicle, which was intraabdominal and associated with splenogonadal fusion. To our knowledge, this is the fourth case of splenogonadal fusion associated with testicular cancer reported. One should always bear in mind the possibility of this association for the left cryptorchid testicle.

Um homem de 36 anos, depois de ser submetido a exames para avaliação de infertilidade masculina, foi diagnosticado com infertilidade masculina primária, criptorquidia bilateral, azoospermia não obstrutiva e fusão esplenogonadal descontínua. Carcinoma in situ estava presente no testículo esquerdo, que tinha localização intra-abdominal e estava associado à fusão esplenogonadal. Esse é o quarto caso de fusão esplenogonadal associada a câncer testicular, segundo nossa avaliação. Deve-se sempre ter em mente a possibilidade dessa associação em testículos criptorquídicos à esquerda.

Testicular adrenal rest tumor in infertile man with congenital adrenal hyperplasia: case report and literature review.

CONTEXT: Synthesis of cortisol and aldosterone is impaired in patients with congenital adrenal hyperplasia (CAH) because of 21-hydroxylase deficiency. Men with CAH have low fertility rates compared with the normal population, and this is related to testicular adrenal rest tumors. Findings of azoospermia in combination with a testicular tumor on ultrasound are likely to have a mechanical cause, especially when in the testicular mediastinum. The preferred treatment method consists of intensive corticoid therapy. However, when the tumor is unresponsive to steroid therapy, surgical treatment should be considered. CASE REPORT: We present the case of a male patient with CAH due to 21-hydroxylase deficiency who presented a testicular tumor and azoospermia. Treatment with low daily corticoid doses had previously been started by an endocrinologist, but after 12 months, no significant change in sperm count was found. Although the adrenocorticotrophic hormone and 17-hydroxyprogesterone levels returned to normal values, the follicle-stimulating hormone (FSH), luteinizing hormone and testosterone levels remained unchanged. Ultrasound examination confirmed that the testicles were small and heterogenous bilaterally, and revealed a mosaic area at the projection of the testis network bilaterally. Magnetic resonance imaging confirmed the finding. Testicular biopsy revealed the presence of preserved spermatogenesis and spermiogenesis in 20% of the seminiferous tubules in the right testicle. The patient underwent testis-sparing tumor resection. After 12 months of follow-up, there was no tumor recurrence but the patient still presented azoospermia and joined an intracytoplasmic sperm injection program.

Development of an animal model for endometrial ablation using trichloroacetic acid.

OBJECTIVE: To develop an animal model of endometrial ablation, and to evaluate the histologic effects of trichloroacetic acid (TCA) in the uterine cavity. DESIGN: Experimental prospective. SETTING: Department of gynecology. PATIENT(S): Thirty female adult rats. INTERVENTION(S): Animals were submitted to injection of TCA in one uterine horn and saline solution in the other. Group 1 was sacrificed the day after the procedure. Group 2 was sacrificed in phase of diestrus. Superficial epithelia of the endometrium, stromal thickness, endometrial glands, and myometrium thickness were compared among the uterine horns of the same rats of group 1. The same evaluation was performed in group 2. Endometrial regeneration was evaluated. MAIN OUTCOME MEASURE(S): Histologic effects. RESULT(S): In group 1, histologic parameters showed endometrial destruction on TCA injected uterine horn. In group 2, four rats died after the procedure, and six rats had no viable material. In the rest of the group, TCA-injected uterine horns showed endometrial destruction. Superficial epithelia of the endometrium and stromal thickness were similar between TCA uterine horn from groups. However, the number of endometrial glands was higher in group 1. CONCLUSION(S): The study developed an experimental model for endometrial ablation. TCA acid is a potent agent for endometrial ablation in rat model. No endometrial regeneration was observed after recovery of cycle.

Testicular adrenal rest tumor in infertile man with congenital adrenal hyperplasia: case report and literature review / Tumor testicular de remanescente adrenal em homem infértil com hiperplasia adrenal congênita: relato de caso e revisão de literatura

CONTEXTO: Pacientes com hiperplasia adrenal congênita (HAC) por deficiência da 21-hidroxilase podem ter a síntese de cortisol e de aldosterona prejudicada. Homens com HAC têm baixas taxas de fertilidade em comparação com a população normal, e isso está relacionado a tumores testiculares de remanescente adrenal. A associação de azoospermia e tumor testicular sugere uma causa mecânica, principalmente quando o tumor é encontrado no mediastino testicular. O método preferencial de tratamento consiste na corticoterapia intensa. No entanto, quando o tumor não é responsivo à terapia com esteroides, o tratamento cirúrgico deve ser considerado. RELATO DE CASO: Apresentamos o caso de um paciente do sexo masculino com HAC por deficiência da 21-hidroxilase, portador de tumor testicular e azoospermia. Em consulta prévia com endocrinologista, o paciente começou tratamento com baixas doses diárias de corticoide, porém, após 12 meses de tratamento, não houve mudança significativa no espermograma. Embora os níveis de hormônio adrenocortitrófico e 17-hidroxiprogesterona tenham se normalizado, os níveis séricos de hormônio folículo-estimulante, hormônio luteinizante e testosterona não se alteraram. Exame ultrassonográfico confirmou testículos bilateralmente diminuídos e heterogêneos, além de área em mosaico na projeção da rede testis bilateralmente. Ressonância nuclear magnética confirmou o achado. Biópsia testicular revelou espermatogênese e espermiogênese preservadas em 20 por cento dos túbulos seminíferos no testículo direito. O paciente foi submetido a cirurgia poupadora testicular, com ressecção tumoral. Após 12 meses de acompanhamento, não houve recorrência tumoral, mas o paciente ainda apresentava azoospermia, sendo integrado no programa de injeção intracitoplasmática de espermatozoides.

Avaliação do impacto da varicocele clínica no volume testicular, parâmetros seminais e níveis de radicais livres de oxigênio no sêmen de homens com fertilidade comprovada / Impact of clinical varicocele on testis size, semen parameters and seminal reactive oxygen species levels in a proven fertile population

Apesar da maioria dos estudos mostrarem que parâmetros seminais anormais, redução do volume testicular e elevação dos níveis de radicais livres de oxigênio (ROS) no sêmen estão associados à presença de varicocele em homens inférteis, a maioria dos homens com varicocele apresenta os parâmetros seminais normais e são capazes de estabelecer gravidez em suas esposas. Nesse sentido, a avaliação desses parâmetros ainda não foi adequadamente estudada em homens com fertilidade comprovada e que apresentam varicocele. Esse estudo teve como objetivo estudar o impacto da varicocele clínica em homens férteis avaliando o volume testicular, parâmetros tradicionais da análise seminal e níveis de radicais livres de oxigênio no sêmen. Esses parâmetros foram avaliados em 113 homens férteis sem varicocele, 43 homens férteis com varicocele e 38 pacientes inférteis com varicocele. A medida do volume testicular foi realizada utilizando-se orquidômetro de Prader. Os parâmetros seminais foram avaliados manualmente segundo os critérios da Organização Mundial da Saúde (OMS) e a morfologia avaliada conforme os critérios da OMS e estrito de Kruger. Os níveis de ROS foram mensurados em sêmen puro utilizando-se a quimioluminescência. Os pacientes inférteis com varicocele apresentaram diminuição dos parâmetros seminais, redução do volume testicular e elevação dos níveis de ROS no sêmen em comparação com os homens férteis, com ou sem varicocele. Os homens férteis com varicocele não apresentaram diferenças significativas em nenhum dos parâmetros avaliados quando comparados aos homens férteis sem varicocele. No entanto, os homens férteis com varicocele grau 3 apresentaram menor concentração espermática e níveis de ROS no sêmen mais altos quando comparados àqueles com grau 1 ou 2. Além disso, o grau de varicocele nos homens férteis apresentou correlação negativa com a concentração espermática e positiva com os níveis de ROS no sêmen...

Although the majority of the studies showed that abnormal seminal parameters, reduced testicular volume and high levels of seminal reactive oxygen species (ROS) are frequently associated with varicocele in infertile population, the majority of the men with varicocele present normal seminal parameters and are able to establish a pregnancy. In view of that, the evaluation of these semen parameters in fertile men with varicocele has not yet been well documented. The objective of our study was to evaluate the impact of clinical varicocele in fertile men assessing testicular volume, routine seminal parameters and seminal ROS levels. These parameters were evaluated in 113 fertile men without varicocele, 43 fertile men with clinical varicocele and 38 infertile patients with varicocele. Testicular volume was measured with a Prader orchidometer. Seminal parameters were assessed according to World Healthy Organization (WHO) guidelines and morphology according to WHO as well as Krugers strict criteria. Measurement of seminal ROS in neat semen was performed using a chemiluminescence assay. Infertile men with varicocele presented lower semen parameters, reduced testicular volume and higher seminal ROS levels compared with fertile men with or without varicocele. Although fertile men with varicocele presented all parameters evaluated similar to fertile men without varicocele, fertile men with varicocele grade 3 presented lower sperm concentration and higher seminal ROS levels compared with fertile men with varicocele grade 1 or 2. In addition, varicocele grade infertile men presented a negative correlation with sperm concentration and a positive correlation with seminal ROS levels. Men with unknown fertility status presenting with palpable varicocele and normal seminal parameters, the presence of increased ROS levels may be indicative of an early recognition of those subjects who will experience...

Use of inverted fluoroscope's C-arm during endoscopic treatment of urinary tract obstruction in pregnancy: a practicable solution to cut radiation.

OBJECTIVES: To describe the use of pulsed fluoroscopic guidance, to perform endoscopic procedures in pregnant women, by inverting the fluoroscope's c-arm using a lead thyroid collar to shield the fetus from the direct X-ray beam. The use of radiation during treatment of pregnant patients with urolithiasis remains a recurring dilemma. METHODS: Between May 2006 and December 2008, endoscopic treatment due to ureteral stones was attempted in 8 pregnant women. In all cases, we use an inverted fluoroscope's c-arm during endoscopic treatment associated with 2 lead neck thyroid collars to shield the uterus, protecting the fetus from direct radiation. Indication for treatment was symptomatic ureteral stones unresponsive to medical treatment in 7 and persistent fever in 1. RESULTS: Mean ureteral stone size was 8.1+/-4.8 mm, located in the left ureter in 5 (62.5%) cases. Three (37.5%) patients had stone located in the upper ureter, 2 (25%) in the middle ureter, and 3 (37.5) in the distal ureter. In 6 cases, ureteral stones were treated using the semi-rigid ureteroscope, whereas in 1 case a flexible ureteroscope was needed. One woman was treated with insertion of a double-J stent due to associated urinary infection. No women has early delivery related to the endoscopic procedure, and all neonates were perfectly normal. CONCLUSIONS: We present a technique for endoscopic procedures in pregnant women inverting the fluoroscope's c-arm and protecting the fetus from the direct X-ray beam. This practical approach should be specially considered when no portable ultrasound and radiologic assistance in available in the operating room.

The systematic use of intraoperative vascular Doppler ultrasound during microsurgical subinguinal varicocelectomy improves precise identification and preservation of testicular blood supply.

OBJECTIVE: To evaluate the impact of systematic use of intraoperative Doppler ultrasound during microsurgical subinguinal varicocele repair. DESIGN: Prospective clinical study. SETTING: Andrology laboratory and male infertility section of the urology department of a tertiary care hospital. PATIENT(S): Two hundred and thirteen men with clinical varicocele. INTERVENTION(S): Subinguinal microsurgical varicocele ligation using an intraoperative vascular Doppler flow detector. MAIN OUTCOME MEASURE(S): Number of veins ligated, lymphatic spared, arteries identified or accidentally ligated. RESULT(S): A statistically significant greater number of arteries were identified and preserved when intraoperative vascular Doppler was used. In addition, the average number of internal spermatic veins ligated was statistically significantly greater in the same group. Accidental artery ligation occurred in two cases (1.1%) in which the Doppler was not applied. There was no statistically significant difference in number of lymphatics spared between groups. CONCLUSION(S): Our findings showed that concomitant use of intraoperative vascular Doppler during microsurgical varicocelectomy allows more arterial branches to be preserved, and more internal spermatic veins are likely to be ligated. This device should be considered an attractive tool to improve surgical outcomes and safety.

Reproductive health in male systemic lupus erythematosus / Saúde reprodutiva em homens com lúpus eritematoso sistêmico

OBJETIVO: Avaliar a saúde reprodutiva em homens com lúpus eritematoso sistêmico (LES) e compará-la com controles saudáveis. MÉTODOS: Vinte e cinco pacientes com LES do sexo masculino foram avaliados com dados demográficos, exame urológico (incluindo parâmetros pubertários e função sexual/erétil), ultrassonografia testicular com Doppler, perfil hormonal, análise seminal, características clínicas e tratamento. O grupo-controle incluiu 25 homens saudáveis. RESULTADOS: A mediana da idade atual foi similar nos pacientes com LES comparada aos controles (26 versus 27 anos, P = 0,756). As frequências de disfunções sexual/erétil foram significativamente maiores nos pacientes com LES em relação aos controles (20 por cento versus 0 por cento, P = 0,0001) e o número de gestações espontâneas foi menor (20 por cento versus 60 por cento, P = 0,0086). Uma tendência de uso infrequente de contraceptivos foi observada em pacientes com LES comparada aos controles (48 por cento versus 76 por cento, P = 0,079). Além disso, as frequências de parâmetros de disfunção gonadal: atrofia testicular avaliada pela ultrassonografia (36 por cento versus 8 por cento, P = 0,037), níveis elevados de FSH e/ou LH (36 por cento versus 0 por cento, P = 0,002) e alterações dos espermatozoides (48 por cento versus 0 por cento, P = 0,0001) foram estatisticamente maiores nos pacientes com LES versus controles. Os pacientes com LES e disfunção sexual/erétil não realizaram atividade sexual no último mês versus 95 por cento dos pacientes sem disfunção (P = 0,0001). Entretanto, nenhuma diferença foi evidenciada nos pacientes com LES com e sem disfunção sexual/erétil em relação a dados demográficos, atividade da doença, dano cumulativo e tratamento. CONCLUSÃO: Este é o primeiro estudo que identificou disfunção sexual/erétil e gonadal em homens lúpicos. Uma abordagem multidisciplinar é essencial para oferecer medidas preventivas para esses pacientes.

OBJECTIVE: To assess reproductive health in male systemic lupus erythematosus (SLE) patients and compare them with controls. METHODS: Twenty-five male SLE patients were evaluated for demographic data, urologic evaluation (including pubertal parameters, sexual/erectile function), testicular Doppler ultrasound, hormone profile, semen analysis, clinical features and treatment. The control group included 25 healthy men. RESULTS: The current median age was similar in SLE patients compared with controls (26 versus 27 years, P = 0.756). The frequencies of sexual/erectile disfunction were significantly higher (20 percent versus 0 percent, P = 0.0001) and the number of spontaneous pregnancies were lower in SLE patients than in controls (20 percent versus 60 percent, P = 0.0086). A trend to low contraceptive use was observed in SLE patients compared with controls (48 percent versus 76 percent, P = 0.079). Moreover, the frequencies of gonadal dysfunction parameters, such as testicular atrophies measured by ultrasound (36 percent versus 8 percent, P = 0.037), elevated FSH and/or LH levels (36 percent versus 0 percent, P = 0.002), and sperm abnormalities (48 percent versus 0 percent, P = 0.0001), were statistically higher in SLE patients versus controls. SLE patients with sexual/erectile disfunction had no sexual activity in the last month versus 95 percent of SLE patients without dysfunction (P = 0.0001). On the other hand, no differences were evidenced in SLE patients with or without sexual/erectile disfunction according to demographic data, disease activity, cumulative damage and treatment. CONCLUSION: This is the first study to identify sexual/erectile and gonadal disfunction in male SLE patients. A multidisciplinary approach is essential in order to offer preventive measures for these patients.

Combined retrograde flexible ureteroscopic lithotripsy with holmium YAG laser for renal calculi associated with ipsilateral ureteral stones.

PURPOSE: The purpose of this study was to evaluate the effectiveness of combined ureteroscopic holmium YAG lithotripsy for renal calculi associated with ipsilateral ureteral stones. MATERIALS AND METHODS: Between August 2002 and March 2007, retrograde flexible ureteroscopic stone treatment was attempted in 351 cases. Indication for treatment was concurrent symptomatic ureteral stones in 63 patients (group I). Additional operative time and perioperative complication rates were compared to a group of 39 patients submitted to ureteroscopic treatment for ureteral calculi exclusively (group II). RESULTS: Mean ureteral stone size was 8.0 +/- 2.6 mm and 8.1 +/- 3.4 mm for groups I and II, respectively. Mean operative time for group I was 67.9 +/- 29.5 minutes and for group 2 was 49.3 +/- 13.2 minutes (p < 0.001). Flexible ureteroscopic therapy for renal calculi increased 18 minutes in the mean operative time. The overall complication rate was 3.1% and 2.5% for groups I and II, respectively (p = 0.87). Mean renal stone size was 10.7 +/- 6.4 mm, overall stone free rate in group I was 81%. However, considering only patients with renal stones smaller than 15 mm, the stone free rate was 88%. Successful treatment occurred in 81% of patients presenting lower pole stones, but only 76% of patients with multiple renal stones became stone free. As expected, stone free rate showed a significant negative correlation with renal stone size (p = 0.03; r = -0.36). Logistic regression model indicated an independent association of renal stones smaller than 15 mm and stone free rate (OR = 13.5; p = 0.01). CONCLUSION: Combined ureteroscopic treatment for ureteral and ipsilateral renal calculi is a safe and attractive option for patients presenting for symptomatic ureteral stone and ipsilateral renal calculi smaller than 15 mm.
