Symptomatic presentation of partial duplication of the ureter in adults is rare. However, there are reports of such conditions being treated with surgical correction with varying degrees of success. We present the case of a 23-year-old woman who underwent what is, to our knowledge, the first reported laparoscopic ureteropyelostomy for symptomatic "yo-yo" reflux.
Serum testosterone levels are increased in athletes after short-term exercise. To investigate whether mechanical compression could contribute to this increase, we subjected 14 male volunteers to mechanical testicular compression via a pneumatic cuff. The serum testosterone levels were sampled at time intervals before, during and after compression. There was a rise in mean serum testosterone levels of 16.7-18.2%, with a maximal increase at 1.5 min after compression was released. Mechanical compression alone did not explain the rise in serum testosterone, although it may have a contributory role.
