RESUMO

OBJECTIVE: The aim of this work was to determine the concordance between the counts obtained with the Makler and the Neubauer chambers in ejaculates from fertile men. DESIGN: Cross sectional study in Reproduction Group, University of Antioquia, Medellin-Colombia. METHODS: 112 ejaculates from fertile men were analyzed in the present study. Sperm count was determined using both chambers, the comparisons between chambers were determined using a Bland-Altman plot. RESULTS: The means values for sperm count were 107.8 and 106.2 x 10(6) sperm/mL using the Makler and the Neubauer chamber, respectively, and there was concordance between both methods. CONCLUSION: Our results show that the determination of sperm concentration with the Makler chamber is as accurate as with the Neubauer chamber and that either chamber can be used in routine semen analyses.

RESUMO

Se estudian 18 pacientes con sospecha clínica de estrechez uretral que estaban en un rango de edad de los 20 a los 78 anos. La etiología de la estrechez era variable pero principalmente post RTU de próstata con el 50 por ciento de los pacientes. Se les realizó a todos una Uretrografía retrógrada y posteriormente una Ecografía de pene utilizando transductor sectorial de 5 mhz. La uretrografía diagnosticó la estrechez uretral en los 18 pacientes y por ECO se realizó en 17 pacientes con una sensibilidad para la ECO del 94 por ciento. En total se encontraron 24 sitios de estrechez en los 18 pacientes, 3 de los cuales se encontraban en la uretra membranosa y sólo 1 se encontró en la ECO. Aquellos localizados en parte bulbar y peneana se diagnosticaron correctamente con el ultrasonido
