Treatment of Renal Stones by Extracorporeal Shockwave Lithotripsy

Aim: Despite the extensive experience with minimal invasive stone therapy, there are still different views on the ideal management of renal stones. Materials and Methods: Analysis of the literature includes more than 14,000 patients. We have compared these data with long–term results of two major stone centers in Germany. The results have been compared concerning the anatomical kidney situation, stone size, stone localization and observation time. Results: According to the importance of residual fragments following extracorporeal shock wave lithotripsy (ESWL), we have to distinguish between clinically insignificant residual fragments and clinically significant residual fragments (CIRF). 24 months following ESWL stone passage occurs as a continous process, and if there are no clinical symptoms, any endoscopic procedure should be considered as overtreatment. According to these results, stone–free rates of patients increase in longer follow–up periods. Newer ESWL technology has increased the percentage of CIRF. Conclusion: We consider ESWL in most patients with renal calculi as first–line treatment, except in patients with renal calculi bigger than 30 mm in diameter.

Based on an extensive review of the literature and our own clinical experience, this article attempts to present clear guidelines for the management of various kidney stones that will be acceptable to clinical urologists and their patients. Regarding our own patients, we compared different studies and discussed the results concerning the anatomical kidney situation, stone size, stone localization and observation time. Stone-free rates of patients with calyceal diverticula calculi range from 4 to 58%, with an increase after longer follow-up periods. According to the importance of residual fragments following extracorporeal shock wave lithotripsy (ESWL), we have to distinguish between clinical insignificant residual fragments and clinical significant residual fragments. 24 months following ESWL, stone passage occurs as a continuous process, and if there are no clinical symptoms, any endoscopic procedure should be considered as over-treatment. Newer ESWL technology has increased the percentage of clinically insignificant residual fragments. We consider percutaneous nephrolithotripsy in most of the patients with renal calculi smaller than 30 mm in diameter only as second-line therapy.

Milk of calcium (MOC) in a small renal cyst or calyceal diverticulum is quite common. Ninety-one small renal cysts with MOC in 61 patients were found within a period of 4 years and 7 months. The main sonographic features are echogenic material layering in the dependent portion of a cyst, associated with reverberation echoes without shadowing. Shadowing was seen when M ilk of calcium (MOC) in a renal cyst or calyceal diverticulum has been considered to be rare 1 • 2 or exceedingly rare, J. and only a few case reportsu -io have appeared in the radiologic and sonographic literature. Traditionally, the reported cysts have been relatively large, characterized by layering of calcium deposits and a resulting acoustic shadow. In our experience, however, small cysts with MOC are quite common. In fact, the ultrasonographic features of MOC in these cysts differ from those reported and consist of layering of the calcium deposits associated with reverberation echoes and with or without shadowing.
