Value of color doppler ultrasound, kub and urinalysis in diagnosis of renal colic due to ureteral stones

Purpose Despite the routine use of helical CT in diagnosis of renal colic, there are recent concerns regarding the radiation exposure, overuse and costs. We attempted in this retrospective study to evaluate the accuracy of ultrasound (gray-scale and color Doppler with twinkling), KUB and urinalysis in diagnosis of renal colic due to ureteral calculi presented in Emergency Room. Materials and Methods A total of 939 consecutive cases of renal colic presented to ER have been managed and evaluated by ureteral ultrasound, KUB and urinalysis for the presence of ureteral stones. Non-confirmatory cases were subjected to Helical CT examination. Results Renal and ureteral ultrasound (gray-scale) alone detected ureteral calculi in 615 cases (65.4%) and after utilizing Color Doppler Ultrasound with twinkling the diagnosis was made with confidence in 935 cases (99.6%) but 4 (0.4%). KUB showed radiopaque stones in 503 (53.6%) patients and no stones were detected in 436 (46.4%). Microhematuria presented in 835 (88.9%) cases while absent in 102 (10.9%). There were 190 (20.3%), 77 (8.2%) and 671 (71.5%) patients with upper, middle and lower ureteral stones respectively. The simultaneous positive findings in US and KUB with microhematuria were found only in 453 (48.2%) cases. Conclusions The use of Color Doppler ultrasound with twinkling increased the detection rate of ureteral stones in acute renal colic patients presented to ER with less radiation exposure. Ultrasound examination as a single modality is superior to KUB and urinalysis in initial diagnosis of renal colic. .

Enfrentamiento del cólico renal en urgencia / Confrontation of renal colic in urgency

Ureteral colic as a nosologic entity, is part of a select group of pathologies that present themselves in an intense and acute form, in which the patient suffers excruciating pain and demands quick diagnosis and treatment. It’s also a common disease in our emergency service, like in other countries.

Tratamiento actual de la litiasis vesicular / Current treatment of vesicular lithiasis

El tratamiento quirúrgico de la litiasis vesicular ha cambiado en los últimos años. La incorporación de las nuevas conductas en la práctica médica diaria no siempre es inmediata. Se argumentan las razones relativas a cuándo operar a un paciente con cálculos en la vesícula biliar, y se documenta cómo este procedimiento se reserva fundamentalmente para los pacientes sintomáticos, considerando el dolor como el síntoma por excelencia. También se expone cómo se ha enfrentado este cambio(AU)
