“…As early as 1986, the annual recurrence rate after ESWL (consider stone‐free rate at 3 months) was reported at 8% 6 . Recurrence after surgical intervention reported by Sutherland, was 40% after 11 years 27 . Stone metaphylaxis reduces the recurrence rate by some 40% 28 .…”

“…Stone metaphylaxis reduces the recurrence rate by some 40% 28 . Medical treatment could lower the recurrence rate after ESWL, endo‐urological procedures, and open surgery 27,28 . Hence, complete metabolic evaluation and stone composition, especially in the high‐risk group, is integral to the selection of the most appropriate intervention to prevent kidney stone recurrence 2,6 …”

Background: The purpose of the present paper was to study the spectrum of stone composition of upper urinary tract calculi by X-ray diffraction crystallography technique, in patients managed at All India Institute of Medical Sciences. Methods:Between 30 April 1998 and 31 March 2003, a total of 1050 urinary calculi (900 renal, 150 ureteric) were analyzed. The stone fragments were collected after extracorporeal shock-wave lithotripsy, or retrieval by endoscopic (percutaneous nephrolithotomy, ureterorenoscopy), laparoscopic and various open surgical procedures. The structural analysis of the stones was done using X-ray diffraction crystallography. Results: Four types of primary and three secondary X-ray diffraction patterns were obtained. The primary patterns were as follows. Pattern A, well organized crystalline structure; pattern B, moderately organized crystalline structure; pattern C, poorly organized crystalline structure; pattern D, very poorly organized crystalline structure. The three secondary patterns mainly highlighted the mixed variety of stones. These patterns were further analyzed and compared with standard X-ray diffraction (powder) photographs. Of the 1050 stones analyzed, 977 (93.04%) were calcium oxalate stones, out of which 80% were calcium oxalate monohydrate (COM) and 20% were calcium oxalate dihydrate (COD). Fifteen were struvite (1.42%) and 19 were apatite (1.80%). Ten were uric acid stones (0.95%) and the remaining 29 (2.76%) were mixed stones (COM + COD and calcium oxalate + uric acid, calcium oxalate + calcium phosphate, and calcium phosphate + magnesium ammonium phosphate). A total of 89.98% of staghorn stones were made of oxalates (COM/+COD) and only 4.02% were struvite. Conclusion: Urinary stone disease in the Indian population is different from that in Western countries, with a larger percentage of patients having calcium oxalate stones, predominantly COM. Also, the majority of staghorn stones (89.98%) were made of oxalates.

“…As early as 1986, the annual recurrence rate after ESWL (consider stone-free rate at 3 months) was reported to be 8% [48]. The recurrence rate after surgical intervention reported by Sutherland [49], was 40% after 11 years. There is a need to develop a cost-analysis model to compare the expenditure of treating recurrent stones versus the cost of prophylaxis against these stones to break the stone cycle and give a cost-effective solution to the patient.…”

Treatment of Renal Stones by Extracorporeal Shockwave Lithotripsy

et al. 2001

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.
