[Clinical problems in urinary obstruction (author's transl)].

It is difficult to define and diagnose urinary obstruction in a meaningful way only by radiographic methods and without involving a urodynamic concept. Urinary infection, urolithiasis and elevated arterial blood pressure are the most common complications found with urinary obstruction. In 70 patients with obstruction of the pelviureteral junction we found infection in 15.7 percent, lithiasis in 27 percent, and arterial hypertension in 27 percent.
