ABSTRACT

Introduction: Bladder lithiasis makes up about 5% of all urinary tract lithiasis. Its existence has been known since 4800 B.C.E. Treatment has been modified throughout the history of open surgery leading to the present day minimally invasive procedures.
Objective: The purpose of this study is to present a percutaneous technique for extracting bladder calculi using Amplatz dilators and sheaths.
Materials and Methods: Patients who sought medical attention in the urology service for bladder lithiasis from June 2006 to July 2007 presenting with bladder calculi between 1.8 and 3 cm in diameter were included in the study. Transurethral resection of the prostate was carried out with Amplatz trocar followed by percutaneous extraction of the stone.
Results: A total of 12 patients were operated on for bladder lithiasis associated with infravesical obstruction. All patients were men and their ages ranged from 35 to 76 years. Eleven of the patients presented with obstructive prostatic growth and one with urethral stenosis. There were no complications resulting from the procedure.
Conclusions: Extractive percutaneous cystolithotomy is a safe, practical and economic method for treating bladder calculi that are smaller than 3 cm. The advantage of this technique is the speed with which it is carried out and the fact that it does not require the use of lithotriptors.
