ABSTRACT

Introduction: from the introduction of minimal invasive methods for treatment of urinary lithiasis, some patients are better managed using the percutaneous nephrolithotomy (PNL) and extracorporeal shock-waves lithotripsy (ESWL) This way combines the advantages of both techniques. Methods: present paper describes some calculi features and the results from the application of ESWL in treatment of residual calculi (RC) after the PNL. Sample includes 65 patients presenting with RC after PNL treated in the «Hermanos Ameijeiras» Clinical Surgical Hospital from April 2006 to December 2009. using the lithotripter MODULITH SLX-MX (STORZ). Results: limit ages were 28 and 74 years. There was predominance of male sex 55.38 %. The mean lithiasis surface was of 1.07 cm2. The RC was more frequent located in multiples calyces 32.31 % and the lower calyx 24.62 %. The 80 was free of lithiasis with one session of ESWL and the 95.38 % after three sessions. After ESWL there was urinary tract infection (UTI), in the 13.85 % of patients remained with RC the 4.62 %. Conclusions: the ESWL continues as an effective tool in treatment of RC after PNL, especially for the fragments non-accessible with the rigid instruments, neither of flexible instruments or the not-available and due its size it not justified a new percutaneous route or a new approach is technically risky.
