Single Shot Tract Dilatation During Percutaneous Nephrolithotomy: Our Experience

Abstract

Objective: To compare safety and efficacy of one-shot dilation and Alken sequential dilatation in PCNL
Method: This prospective study conducted on 60 renal stones patients underwent supine PCNL at
Department of urology, Lahore General Hospital, Lahore from June 2020 to July 2021.Tract dilatation was
performed using Alken dilatation (Group A, 30 patients) or One-shot dilatation (Group B, 30 patients).
Results: The mean age of patients in Group A and Group B were comparable (P=0.78). Stone clearance
between group A and B was not different (86.7% v 83.3% respectively, p=1). Group B had a lower mean
fluoroscopy time than group A. (124.13±22.40 Sec Vs 102.16±32.26 Sec, P=.003). Mean tract dilatation was
shorter in group B than group A (5.06 ±0.80 min Vs 5.94 ±0.87 min, p<.001). Mean hemoglobin drop was
similar in both groups (1.62±.56 g/dl Vs 1.38 ±.36 g/dl, P=.055). The complications among the groups were
not significantly different.
Conclusion: One-Shot dilatation is a safe and effective technique for creation of nephrostomy tract in PCNL.
That can reduce tract dilatation time and X-rays exposure time.
