ABSTRACT

Background: Identification of risk factors for urolith stones formed in the urinary tract could help in preventing the recurrence. Urolith stones analysis utilized modern technology which is unfortunately not done in Pakistan on a routine basis. Development of renal failure may occur due to complications and urinary tract affected by uroliths.

Objective: The current study aims to determine the composition of urolith stones seen in patients admitted in single Centre in Pakistan.

Materials and Methods: This cross-sectional study was carried out on urolithstones composition surgically removed through minimum access procedure at Urology department of Ayub Teaching Hospital, Abbottabad for period of six months from October 2020 to March 2021. Urinary stones composition was measured through qualitative tests such as infrared and crystallography spectroscopy. Statistical analysis was performed in SPSS version 20.

Results: A total of 82 patients with mean age ± SD 45.3±11.7 years having urinary stones were investigated in this cross-sectional study. Male to female ratio was 1.9:1. Male patients (54) (65.85%) were dominant over females (28) (34.15%) in term of stones removal. A high occurrence for urinary stones was bladder or upper urinary tract (81.6%) irrespective of their gender. Calcium containing stones were predominant in ureter, urethra and renal followed by struvite stones (56.8%). Two-third stones in struvite stones were in lower tract while uric acid, calcium phosphates and calcium oxalate were found in upper tract. Calcium oxalate account for 92.60% with mixed composition stones.

Conclusion: Our study concluded that the majority of uroliths constitute calcium oxalate or phosphates and struvite stones in our setting. Uroliths formation is caused by urinary tract infection as indicated in our study. Calcium oxalate was the most common among these stones. Struvite stones were the least common one. The prevalence of stones was dominant in male patients compared to female patients. The anatomical location for calcium oxalate and struvite stones was lower tract and bladder respectively.
