Abstract
Objectives: To compare the outcomes of one step dilatation versus metallic telescopic dilatation in PCNL.
Materials and Methods: Following approval from the ethical committee of The Kidney Centre Post graduate training Institute, this study was conducted within the Department of Urology from January 2022 to September 2022. A total of 90 patients were enrolled. Participants were randomized into two groups using lottery method: Group A underwent dilatation using the one-step dilatation method, while Group B underwent dilatation using metallic telescopic dilatation. A predesigned questionnaire was used to collect the data.
Results: The mean age of group A patients and group B patients were 39.36±10.0 and 37.60±11.3 respectively. The mean size of the stone was 3.15±0.69 cm in Group A and 3.41±0.70 cm in Group B with an insignificant p-value of 0.09. The stone free rate was 39(86.7%) and 32(71.1%) in group A and Group B respectively with an insignificant p-value of 0.07. There was a statistically significant difference between both groups regarding the tract creation time (2.28±0.47 and 4.01±0.65) and Fluoroscopic Exposure Time (65.37±17.9 seconds and 122.0±23.8 seconds) revealing a significant p-value of <0.001.
Conclusion: The study concludes that one step dilatation is more effective as compared to metallic telescopic dilatation for patients undergoing nephrolithotomy in terms of blood loss, improved renal function, tract creation time, and fluoroscopy exposure time without any effect on stone free rate.
