ABSTRACT

Objective: To compare the analgesic effect of the petroleum jelly and the lubricating jelly used as contact medium in patients with urolithiasis subjected to external shock wave lithotripsy. Material and methods: We select patients with urolithiasis that received treatment with external shock wave lithotripsy between march 2002 to may 2002; using lubricating jelly as contact medium in group A and petroleum jelly in group B, and being evaluated the pain perception by a visual pain score in each one of the groups. Results: 94 patients were studied, 46 in the group A and 48 in the group B, with a score average in the visual pain score of 7.43 (± 2.09) in the group A (p = 0.122), and 7.06 (± 1.19) in the group B (p = 0.001). The average of intensity of the shock wave was of 51.06% (± 15.88) in the group A (p = 0.0014), and 59.22% (± 14.13) in the group B (p = 0.106). Conclusions: This study demonstrates that the petroleum jelly used as contact medium during the extracorporeal shock wave lithotripsy, presents a significantly smaller score in the visual pain score in comparison with the lubricating jelly; also, the patients with lubricating jelly reach a shock wave intensity significantly smaller in comparison with petroleum jelly.
