title: Diffusion-weighted MRI of the testis in hydrocele: a pilot study.
abstract: OBJECTIVE
  To investigate the effects of increased pressure due to the accumulated fluid around testis in hydrocele on testis diffusion and whether this effect (if any) is correlated with the amount of fluid and duration of hydrocele.
  
  
  METHODS
  49 patients with unilateral hydrocele were evaluated by magnetic resonance diffusion-weighted imaging.
  
  
  RESULTS
  In the study group, while the apparent diffusion coefficient (ADC) values of the testicles with hydrocele differed significantly before and 3 months after the hydrocelectomy (p = 0.001), the ADC values of the testicles without hydrocele were not statistically different (p = 0.101). There was a significant negative correlation between the ADC values of the testicles with hydrocele and the amount of the liquid aspirated during the hydrocelectomy (r = -0.615, p = 0.001). There was no correlation between the ADC values of testis and the duration of hydrocele (r = -287, p = 0.156). This is supported by the findings of the present study of reduced ADC values of testis, meaning reduced diffusion of the testis, with an increasing amount of fluid.
  
  
  CONCLUSIONS
  The pressure of the fluid was suggested to show a mechanical effect that plays an important role in the dysfunction of the testis. The possible dysfunctions of the testicular tissue suggest that they may have a negative effect on fertility.
