Hematuria is the most common complication of lithotripsy. It may be possible, however uncommon, that lower back pain can also result. The symptoms you describe may be consistent with sciatica. You may want to consider further imaging tests (i.e. lumbar MRI) to evaluate any nerve compression. Typically (approximately 75-80%) the symptoms of sciatica resolve on their own or with conservative therapy.
I would be evaluated by a physician to ensure there isn't any other cause of the sciatica (i.e. a herniated disk). Physical therapy, anti-inflammatories, and/or further imaging would be the options to consider.
Followup with your personal physician is essential.
