Effectiveness of ultrasonography and plain abdominal graphy in the follow-up of patients after retrograde intrarenal surgery

26584

Objectives: It was aimed to evaluate the effectiveness of combined use of ultrasonography (US) and plain radiography (PR) in the postoperative follow-up of patients undergoing retrograde intrarenal surgery (RIRS). Materials and methods: The charts of 207 patients who underwent RIRS for renal stones in a 3-years-period were retrospectively reviewed. Fifty-eight patients were included to study who were evaluated with combination of urinary US, PR and computed tomography (CT) at 1 month after surgery. Results: Of 58 procedures with perioperative complete stone fragmentation, 49 were completely stone-free (84.4%), while fragments (≥ 3 mm) were observed in 9 patients and hydronephrosis was detected in 5 patients (8.6%) on the CT. Of the 9 residual stones and 5 hydronephrosis, the radiologists truly diagnosed 6 stones (66.6%) and 5 hydronephrosis (100%) by using the combination of US and PR. The sensitivity, specificity, positive and negative predictive values of US and PR for detecting presence of residual stone and hydronephrosis were 66.6% and 100%, 98% and 98%, 85.7% and 83.3%, 94.2% and 100%, respectively. Conclusions: A combination of urinary US and plain film has clear advantages about lack of radiation exposure over CT scan and it is a highly specific and sensitive test for detecting hydronephrosis. However this procedure has limited accuracy for detecting small residual stones, so we believe that CT scan is only necessary when patient has persistent pain or sonographic evidence of hydronephrosis is present.
