Abstract

Background & Objectives: Percutaneous nephrolithotomy in individuals with prior open stone operations might be difficult. The purpose of our research was to compare the efficacy and complications of the procedure in individuals who had previous open renal stone surgeries with patients without previous open renal surgeries.

Methods: This is a prospective comparative study carried out on 115 patients between May 2020 to April 2021, the patients were classified into two groups. Group 1 (n=50) had previously undergone open renal stone surgery. Group 2 (n=65) had no prior open operations. Both groups' demographic data, stone parameters, operative and fluoroscopy time, stone-free rate, hospital stays, and perioperative and postoperative complications were compared.

Results: The demographic data and stone parameters were comparable between the two groups, the total operative time and fluoroscopic time were significantly higher for group 1 versus group 2 (74.18 min vs 62.89 min), (22.12 min vs 11.69 min) respectively. Postoperative hospital stays nephrostomy tube removal time, and mean hemoglobin drops were also similar, 6 patients in group 1 received a blood transfusion in comparison to 2 patients in group 2, but statistically was not significant. There were no statistically significant differences between groups 1 and 2 in terms of perioperative and postoperative complications.

Conclusion: Individuals with a history of open renal stone operations who have subsequent percutaneous nephrolithotomy may require more fluoroscopic and operating time, although the success rate and overall morbidities were the same in both groups.
