Postprocedural symptoms in children who undergo imaging studies of the urinary tract: is it the contrast material or the catheter?
The frequency, nature, and duration of postprocedural symptoms in 100 children who underwent voiding cystourethrography (VCUG) after administration of 17.2% wt/vol iothalamate meglumine, 100 children who underwent radionuclide cystography (RNC) after administration of saline and technetium-99m pertechnetate, and 28 children catheterized before diuretic renal scintigraphy (DRS) were prospectively assessed with telephone follow-up. All children were aged 2 years or older; 61 were boys, 167 were girls. Postprocedural symptoms occurred in 80 children (35.1%). The frequency of postprocedural symptoms was nearly identical in the VCUG group and the two other groups. Boys (n = 33 [54%]) had symptoms significantly more often than girls (n = 47 [28%]) (P less than or equal to .0005). Dysuria was the most common symptom (n = 75 [32.9%]) and was frequently accompanied in younger children by anxiety over going to the bathroom. Symptoms disappeared within 24 hours in 32 of 80 children (40%) and lasted 4-10 days in eight children. It is concluded that most postprocedural symptoms in children who undergo VCUG, RNC, or DRS are secondary to catheterization rather than to the use of iodinated contrast material.
