Consequently, other imaging methods have been used or have been developed. For many years, IVU has been used for the diagnosis of urinary tract obstruction. Signs of obstruction include the demonstration of dilatation and delayed filling of the collecting system (Fig. 5.12a). On imaging, especially on IVU, the dilatation of the renal pelvis and calyces... 

Intermittent UPJ obstruction is a condition where stable conditions alternate with acute dilatation of the collecting system. During an acute phenomenon, the patient experiences pain, nausea and vomiting (DietTs crisis). The clue to the diagnosis is thickening of the pelvic wall on US during convalescence (Tsai 2006). 

The diagnosis is suspected when decreased renal function is associated with dilatation of the collecting system on US (Fig. 3.8). However, such dilatation may be passive, due to two phenomena either a full bladder, requiring repeated US after complete voiding or bladder catheterization, or a loss of smooth-muscle tonus secondary to ureteral denervation. Unfortunately, this latter mechanism is difficult to confirm usually it occurs very early after transplantation and dilatation is observed during follow-up, despite persistently normal renal function.
