Metodologia da análise seminal para pacientes azoospérmicos no Laboratório Fleury

ResumoA azoospermia é definida como a ausência de espermatozoide no líquido seminal ejaculado pelo homem depois de aplicada a técnica de centrifugação em pelo menos duas amostras. Dada a importância de um diagnóstico correto da análise seminal para os casais, toda amostra que não apresentar espermatozoides no exame a fresco deve seguir em avaliação laboratorial. Com isso, o presente estudo tem como objetivo analisar os resultados de centrifugação de uma alíquota do sêmen ejaculado ou de todo o volume ejaculado de pacientes com diagnóstico de azoospermia para determinar qual o melhor método a ser empregado na análise seminal para esse grupo de pacientes.AbstractThe azoospermia is defined as the absence of sperm in the ejaculate by the seminal fluid man after centrifugation technique conducted in at least two samples. Given the importance of a correct diagnosis of the seminal analysis for couples, all sample no sperm present in fresh examination should follow in laboratory tests. Thus the present study aims to analyze the results of a spin rate of ejaculate or all of the ejaculate volume of patients with azoospermia to determine the best method to be used in semen analysis for this group of patients

Análise de colecistectomias videolaparoscópicas no Hospital de Clínicas de Porto Alegre

OBJECTIVE: Laparoscopic cholecystectomy (LC) is the treatment of choice for cholelithiasis. Our objective was to assess the results of LC in comparison with previous data published in 1994.PATIENTS AND METHODS: From 1992 to 1999, 2,300 patients were submitted to surgery at the Hospital de Clínicas de Porto Alegre. The medical records of 1,540 of these patients were assessed retrospectively. The variables evaluated were preoperative diagnosis, duration of hospital stay and of surgery, intra- and postoperative complications, conversion rate to open surgery, and anatomicopathological examination of the gallbladder.RESULTS: The most common preoperative diagnosis was of symptomatic gallstones (92%); the average hospital stay was of 3.6 ± 6 days (median of 2 days); the average duration of surgery was of 89.5 ± 38 minutes; the most frequent intraoperative complications were gallbladder rupture (7.3%), calculi in peritoneum (0.8%), and iatrogenic bile duct injury (0.2%); and the postoperative complications reported were wound infection (1.3%), retained stones (0.6%), and biliary peritonitis (0.5%). The conversion rate to open procedure was of 2.5%, and reoperation was necessary in 1.8% of cases. There was only one death (0.06%).CONCLUSION: In comparison to data from a previous experience, there has been an improvement in LC results, but additional technical improvements can still be made. OBJETIVO: A colecistectomia videolaparoscópica (CVL) é o tratamento preferencial da colelitíase. O objetivo deste trabalho é avaliar os resultados da CVL comparando com a experiência inicial relatada em 1994.PACIENTES E MÉTODOS: De 1992 a 1999 foram operados 2.300 pacientes no Hospital de Clínicas de Porto Alegre. Deste total foram revisados retrospectivamente 1.540 prontuários. As variáveis analisadas foram a indicação cirúrgica, o tempo de internação hospitalar e cirúrgico, as complicações trans e pós-operatórias, a taxa de conversão para cirurgia aberta e o exame anatomopatológico da vesícula biliar.RESULTADOS: A principal indicação de cirurgia foi a colelitíase sintomática (92%). O tempo de internação hospitalar foi 3,6 ± 6 dias e a mediana de 2 dias e o tempo cirúrgico médio de 89,5 ± 38 minutos. As principais complicações intra-operatórias foram a perfuração da vesícula biliar (7,3%), a queda de cálculos na cavidade (0,8%) e lesão iatrogênica de via biliar (0,2%). No pós-operatório, as complicações mais freqüentes foram a infecção de ferida operatória (1,3%), a coledocolitíase residual (0,6%) e o coleperitônio (0,5%). A taxa de conversão foi de 2,5% e de reoperação de 1,8%. Houve apenas um óbito (0,06%).CONCLUSÕES: Em relação à experiência inicial, a CVL evoluiu muito, mas ainda pode ser aprimorada tecnicamente. &nbsp

Post-vasectomy semen analysis: Optimizing laboratory procedures and test interpretation through a clinical audit and global survey of practices

Purpose: The success of vasectomy is determined by the outcome of a post-vasectomy semen analysis (PVSA). This article describes a step-by-step procedure to perform PVSA accurately, report data from patients who underwent post vasectomy semen analysis between 2015 and 2021 experience, along with results from an international online survey on clinical practice. Materials and Methods: We present a detailed step-by-step protocol for performing and interpretating PVSA testing, along with recommendations for proficiency testing, competency assessment for performing PVSA, and clinical and laboratory scenarios. Moreover, we conducted an analysis of 1,114 PVSA performed at the Cleveland Clinic’s Andrology Laboratory and an online survey to understand clinician responses to the PVSA results in various countries. Results: Results from our clinical experience showed that 92.1% of patients passed PVSA, with 7.9% being further tested. A total of 78 experts from 19 countries participated in the survey, and the majority reported to use time from vasectomy rather than the number of ejaculations as criterion to request PVSA. A high percentage of responders reported permitting unprotected intercourse only if PVSA samples show azoospermia while, in the presence of few non-motile sperm, the majority of responders suggested using alternative contraception, followed by another PVSA. In the presence of motile sperm, the majority of participants asked for further PVSA testing. Repeat vasectomy was mainly recommended if motile sperm were observed after multiple PVSA’s. A large percentage reported to recommend a second PVSA due to the possibility of legal actions. Conclusions: Our results highlighted varying clinical practices around the globe, with controversy over the significance of non-motile sperm in the PVSA sample. Our data suggest that less stringent AUA guidelines would help improve test compliance. A large longitudinal multi-center study would clarify various doubts related to timing and interpretation of PVSA and would also help us to understand, and perhaps predict, recanalization and the potential for future failure of a vasectomy.American Center for Reproductive Medicin
