SINGLE STEP RENAL ACCESS DILATATION IN PERCUTANEOUS NEPHROLITHOTOMY

Abstract

Percutaneous nephrolithotomy (PCNL) is the first-line treatment for large or multiple kidney stones and stones in the inferior calyx. This is a prospective study conducted on patients for whom percutaneous nephrolithotomy (PCNL) was done for the management of kidney stone disease. The study was conducted at The Urology Department, AL Demerdash Hospitals, Ain Shams University & Nasser Institute Hospital during the period between April 2014 and May 2015, All cases were fulfilling the inclusion criteria. our patients were classified into (2) groups, each group was 20 patients (twenty patients) according to the type of renal access dilatation: 1. Group ( A ) = AMPLATZ = Single Amplatz 30 Fr dilator over Central Alken. 2. = Group (B) = Balloon = Balloon Access dilatation The aim of the current study was To perform a single step renal access dilatation (RD) during percutaneous nephrolithotomy (PCNL) by using directly A 30-F Amplatz dilator over a central Alken dilator, Comparing It to Balloon renal access dilatation in a trial to reduce the operative duration , financial costs, and blood loss during renal dilatation. All patients were subjected to preoperative evaluation by history and physical examination.
