Introduction: Ultrasonograghy plays an important role in the evaluation of urinary tract disorders in cases of medical or surgical renal disorders, because of its lower cost, availability, and lack of ionizing radiation and because with it there is no need for contrast material injection or ingestion. It needs no intervention or preparation and specifically can differentiate between the multiple causes of flank pain. Urologist-operated sonography is a quick, cost-effective, and time-saving modality for both the physician and patient for obtaining first or final diagnosis. Based on its results, patients can be selected for appropriate management and further assessment.
Materials and methods: The efficacy of ultrasound examination by a trained urologist in the differentiation of urological emergencies admitted in a district private clinic was studied. Between April 2008 and April 2010, a total of 724 patients (1448 renal units) had renal ultrasound performed by a trained urologist on acute admission. The sonographic findings were compared with subsequent definitive radiological investigations performed as needed, such as KUB (kidney, ureter, bladder) or IVP (intravenous pyelogram). Patient satisfaction and permission for ultrasonography were evaluated by oral consent. Loin pain was the presenting symptom in 45% of the patients (n = 326 cases).
Results: Diagnosis was achieved in 96% of patients. Further evaluations were requested as needed in suspicious cases. If any hydronephrosis was detected and patients' history and/or complaints were suggestive of renal or ureteral stones, an outpatient KUB was requested. For more complex situations, IVP was the next option. Abnormal findings were recorded in 184 cases (25.5%). Mild to moderate unilateral hydronephrosis with or without hydronephrosis was the most common finding observed sonographically. The sensitivity of our ultrasonography evaluation was 99.7%.
Conclusion: Office urologist-operated sonograghy may supplement the information available through routine history, physical examination, and laboratory studies. Our study shows that urological trainees can use ultrasound with high levels of accuracy, thereby improving patient management with a high level of patient satisfaction.
