Objective: To evaluate the feasibility and safety of the modified urethral pull-through procedure for the treatment of posterior urethral stricture or atresia.
Methods: We retrospectively analyzed 212 cases of posterior urethral stricture or atresia treated by the modified urethral pull-through procedure. The length of the stricture or atresia was 1.

Objective: To evaluate the cardiopulmonary exercise capacity in patients with essential hypertension (EH) complicating with or without left ventricular hypertrophy (LVH).
Methods: Graded maximal exercise test on the bicycle ergometer with respiratory gas analysis were performed in 30 gender and age matched normotensive controls, 40 EH patients without LVH and 30 EH patients with LVH (LVMI>125 g/m2 in males and > 120 g/m2 in females). Metabolic equivalents (METs), oxygen uptake (VO2), oxygen uptake to body mass ratio (VO2/kg) and oxygen uptake to heart beat ratio (VO2/HR) at time of reaching anaerobic threshold (AT) and at maximal oxygen uptake (VO2max) were measured and compared.
