Abstract

Objectives: To determine the outcome of extracorporporeal shock waves lithotripsy for high density renal stone on non-contrast computed tomography. Study Design: Descriptive study. Setting: Urology Department of Sindh Institute of Urology and Transplantation, Karachi. Period: 1st November 2017 to 31st October 2018. Material & Method: Patients in the age range of 25-75 years were selected, irrespective of their gender. After 12 weeks final outcome of ESWL was measured by performing plain X-ray KUB films before and after procedure. Satisfactory outcome was defined as stone clearance in <3 sessions of the procedure. Results: According to our inclusion and exclusion criteria 122 patients were selected for ESWL. Among them there were 41.8 (n=51) females and 58.1% (n=71) males. The mean age of the patients was found to be 34.08+ 9.53 years. Approximately more than half of the patients 57.4% (n=70) patients were present in the age group of in ≤35 years. The mean size of the stone was 1.51+ 0.5 cm whereas mean stone density as scan was 772 + 22.2HU. Patients were having renal or ureteric stones for mean duration of 2.07 + 0.31 months. Around 69.7% of patients had renal stones and 30.3% of patients had ureteric stones. Stone clearance was found in 58.2% (n=71) of the patients. Conclusion: Non-contrast enhanced CT scan is the most frequently used investigation to diagnose kidney stones and decide its treatment modality. Outcome of ESWL also depends on various factors as mentioned in the study.
