Study of Role of Magnetic Resonance Urography (MRU) and Comparison with Conventional Radiology in the Diagnosis of Complex Renal Anomalies: A Tertiary Care Centre Experience

Anatomical renal anomalies are one of the most commonly occurring renal anomalies. Most of these anomalies require series of investigations for the proper diagnosis. We tried to compare the results of conventional radiological investigations with magnetic resonance urography in the diagnosis of complex renal anomalies. Materials and methods: This was a prospective study done over a period of five years from 2006 to 2011. All the patients with suspected or diagnosed presence of renal anomalies were investigated by ultrasound (USG), Intravenous urography (IVU), micturating cystourethrogram (MCU), magnetic resonance urography (MRU), retrograde urethrography, cystogenitoscopy, renal scans as per the indication in the case. Results: Total sixty three patients were studied over the period. The most common complex renal anomaly diagnosed was duplex system and conventional radiological investigations were useful in the diagnosis of less than 50% patients. Female patients outnumbered male patients in having complex renal anomalies. MRU was diagnostic in most of the patients with such anomalies and excellent mode of investigation for functional and anatomical details. Conclusion: MRU is better than conventional radiological investigations in the diagnosis of complex renal anomalies.
