Abstract
Introduction:
Percutaneous nephrolithotomy (PCNL) is considered to be the gold standard management for renal calculi. The purpose of this study is to comprehend the overall alterations in renal volume occurring after PCNL. The changes in the kidney’s total volume in individual patients will be examined by ultrasonography pre and postoperatively, and it will be correlated with GFR.
Materials and methods:
It was a prospective observational study performed over 70 participants, conducted at the department of Urology of a tertiary care hospital in Eastern India. Each patients were evaluated with pre and post PCNL USG for kidney volume and GFR. The data was statistically evaluated by SPSS software.
Results:
The preoperative and post operative calculated mean GFR was 96.030 ± 18.922 ml and 86.681 ± 16.938 ml,volume was 127.258 ± 25.705 and 123,678 ± 26.357 respectively . There was statistically significant decrease in GFR and volume following PCNL. It also shows that patients who underwent single puncture PCNL had significantly less decrease in GFR and kidney volume compared to multiple puncture PCNL. Moreover, the calculated mean change in GFR and volume were significantly less seen in single puncture—one step dilatation and single puncture—serial dilatation as compared to multiple puncture—one step dilatation and multiple puncture—serial dilatation.
Conclusion:
Our study showed that there was significant changes in the renal volume and GFR following PCNL . So, a sonographic estimation of renal dimensions and GFR calculation after PCNL will help in the prognosis and further follow up of patients. A Single puncture had a better operative outcome and less adverse consequences with respect to GFR, volume change and for renal function as compared to multiple puncture.
