The main disadvantages of MRI of the abdomen and pelvis are poor accuracy for the detection of small urothelial calculi and reduced accuracy for detection of emphysematous pyelonephritis, [31,32]. MRI Abdomen There is limited literature on the use of MRI of the abdomen in the evaluation of suspected APN in a patient with a pelvic renal transplant and native kidneys in situ. APN is rare in native kidneys, and abdominal imaging would not include complete imaging of the pelvic transplant kidney(s), which would likely miss important pathology in the transplant kidney [1,8,14-21]. MRI Pelvis There is limited literature on the use of MRI of the pelvis in the evaluation of suspected APN in a patient with a pelvic renal transplant and native kidneys in situ. Pelvic MRI alone would not include evaluation of the native kidneys. MRI of the abdomen and pelvis would be more comprehensive for identification of the source of the APN. MRU There is no current literature specific to the use of MRU in the evaluation of suspected APN in patients with a pelvic renal transplant and native kidneys in situ. The excretory phase of MRU does not confer additional benefit with respect to detection and characterization of APN in a pregnant patient. Radiography Abdomen and Pelvis Radiography of the abdomen and pelvis is not beneficial in the imaging evaluation for suspected APN in a patient with a pelvic renal transplant and native kidneys in situ [15]. Radiography Intravenous Urography IVU is not beneficial in the imaging evaluation for suspected APN in a patient with a pelvic renal transplant and native kidneys in situ [15]. US Abdomen APN is rare in native kidneys. Because an US of the abdomen would not include complete imaging of the pelvic transplant kidney(s), the examination is not likely to diagnose APN [1,8,14-21]. US Color Doppler Kidneys and Bladder Retroperitoneal APN is most commonly an issue with the transplant kidney.
