Value of prone position ultrasound in evaluating retrorenal colon in patients scheduled for percutaneous nephrolithotomy
摘要
Abstract
Objective To evaluate the application value of prone-position ultrasound in assessing retrorenal colon among patients scheduled for percutaneous nephrolithotomy(PCNL).Methods A total of 651 patients scheduled for PCNL were enrolled.All patients underwent preoperative supine-position computed tomography(CT)and prone-position ultrasound to assess retrorenal colon.Retro-renal colon was defined as segment of the colon located posterior to the kidney,with its inferior mar-gin extending beyond the lower pole of the kidney.The degree of coverage was classified as mild(≤3.0 cm),moderate(＞3.0 cm without extending beyond the renal hilum)and severe(extending be-yond the renal hilum).Patients diagnosed with retrorenal colon by ultrasound underwent further eval-uation using prone-position CT.Concordance between ultrasound and supine-position or prone-posi-tion CT in diagnosing and classifying retrorenal colon was compared,and the impact on puncture pathway selection and surgical approach was analyzed.Results Among 651 patients,prone-position ultrasound identified retrorenal colon in 57 patients,including 43 mild cases,11 moderate cases,and 3 severe cases.Prone-position CT identified retrorenal colon in 55 patients,including 42 mild cases,10 moderate cases,and 3 severe cases.Supine CT identified retrorenal colon in 26 patients,inclu-ding 23 mild cases,2 moderate cases,and 1 severe case.The detection rate of retrorenal colon by supine CT was significantly lower than that by prone-position ultrasound(P＜0.05).In 12 patients(4 mild cases,7 moderate cases,1 severe case),the puncture pathway was modified based on ultra-sound diagnosis,and 2 patients with severe involvement underwent a change in surgical approach.Conclusion Prone-position ultrasound demonstrates good agreement with prone-position CT in the assessment of retrorenal colon.关键词
