Single centre study of stone clearance with ureterorenoscope & lithoclast for ureteric calculi; our experience.

Abstract

To decide the adequacy of ureterorenoscope by utilizing lithoclast for distal ureteric stone clearance. Study Design: Longitudinal study. Setting: Department of urology Aziz Bhatti Shaheed Teaching Hospital. Period: Feb 2014 to Dec 2016. Materials and Methods: 32 patients from medical record who underwent for stone clearance with ureteroscopy followed by lithoclast. The patients with larger upper ureteral stones were enrolled in the study though patients with stone size<1cm and co-morbidities were not included in the study. The characteristic of patients and stone, treatment modality & outcome i.e. efficacy in terms of “successful stone clearance” were determined. Results: The average age of 32 patients was 34.28±10.11 years. 18 (56.3%) of the patients were females whereas 14 (43.7%) were males. Ureteric stones were present on both right and left sides in 17 (54%) and 15(46%) patients. Bilateral ureteric stone was present in 2 (6.25%) patients. The efficacy was reported as 96% for the stone size of 1-1.5cm and 92% for the stone size of 1.6-3cm. Conclusions: We concluded that Ureterorenoscope followed by Lithoclast is the useful and safest procedure for stone clearance.
