Primary Outcome Measures

Name	Time	Method
Primary endpoint was functional success, defined as correction of obstruction.<br><br>The evaluation of functional outcome/success based on objective (intravenous urography (IVU) and renal scintigraphy) and subjective findings (flank pain). Success was defined as no obstruction in the IVU and undelayed and unobstructed drainage in the scintigraphy (T1/2 < 20 min), stable or improved split kidney function on the affected side and no residual flank pain.<br>[IVU took place at 3 months and renal scintigraphies were performed at 6, 12 and 24 months. Subjective findings were simultaneously evaluated at these timepoints.<br><br>All patients were and will be followed for a total of 5 years. Our median follow up so far is 36 months. However, eventual failures (recurrent uretero-pelvic junction obstruction) following pyeloplasty are mainly expected to occur within the first year after surgery.]
