LABRADA, María Victoria et al. Treatment of the pyelic lithiasis using the MODULITH SLX-NX (STORZ) lithotriptor. Rev Cubana Cir [online]. 2010, vol.49, n.3. ISSN 0034-7493.

INTRODUCTION. The urinary lithiasis is a disease with a high prevalence and recurrence and the hospitals can not give a surgical solution as quickly as possible. The shock waves extracorporeal lithotripsy (SWEL) is the first choice of treatment and the resolution rates fluctuate from 33 to 90%. The objective of present study was to analyze our results using the MODULITH SLX-MX (STORZ) lithotriptor for the monotherapy of renal pelvis lithiasis. METHODS. The patients presenting with pyelic lithiasis and any other treatment were included in study that were divided into four groups according the lithiasis surface and were related to therapeutics (sessions, chock waves, energy, complications and application of auxiliary procedures, complementary manoeuvres and course). RESULTS. Most of patients had 2 cm² calculi and more than the 92% were solved with only one session. More than 94% had not complications without auxiliary procedures in more than 97% of the cases. CONCLUSIONS. It was possible to obtain good results in more than 97% of the cases using monotherapy-SWEL of pyelic lithiasis of 4 cm² using the MODULITH SLX-MX (STORZ) lithotriptor. The better results were obtained in calculi of 3 cm² and more than the 99% belongs to calculi of 2 cm². The advantages of this device were mainly due to its high effectiveness level and to fact that it achieves a fine fragmentation allowing the total removal of calculi. Thus, it is possible to obtain a high rate resolution without rests of lithiasis in more than 97% of the cases and with a minimum of complementary manoeuvres.
