Abstract：Objective： Study the efficacy and safety of percutaneous nephrolithotomy (PCNL) for recurrent kidney calculi after trans-lumbar open surgery. Methods： From April 2016 to May 2018, 12 cases of recurrent kidney calculi after trans-lumbar open surgery and 40 cases of kidney calculi without trans-lumbar open surgery history were given PCNL. Preoperative data such as leukocyte counts of urine routine, the degree of hydronephrosis, the thickness of the renal cortex, and the number of calyceal involved by calculi were compared between two groups. The operation time, and postoperative data (including fever rate, procalcitonin (PCT) values, the rate of abnormal white blood cell counts, reduction rate of hemoglobin, and the number of residual stones) were compared between two groups. Results： There was significant difference between the group without trans-lumbar open surgery history and the group of recurrent kidney calculi after trans-lumbar open surgery in the leukocyte counts of urine routine, the degree of hydronephrosis, the thickness of the renal cortex, and the number of calyceal involved by calculi (P<0.05). Also, there was significant difference between the group without trans-lumbar open surgery history and the group of recurrent kidney calculi after trans-lumbar open surgery in the fever rate, the rate of abnormal white blood cell counts, PCT values, operation time and the number of residual stones (all P<0.05). However, there was no significant difference in postoperative hemoglobin reduction between two groups (P>0.05). Conclusions： Compared with the patients without trans-lumbar open surgery history, the conditions of kidney after trans-lumbar open surgery are poor, the operative difficulty is great, the risk of postoperative infection is high and the efficacy of operation is generally poor. Urologists should have more experience and require detailed preoperative preparation.
