Frequency of renal stone disease in patients with urinary tract infection.

BACKGROUND To determine incidence of renal stone disease in patients with urinary tract infection, this cross sectional study was conducted at Surgical Unit of District Head Quarters Hospital, Charsadda over a period of one year from January to December 2005. METHODS One hundred consecutive patients were enrolled in this study. All those patients who presented with urinary symptoms were included. While patients with lower urinary tract stones, upper urinary tract stones with renal failure, renal tumours and previous history of renal stones disease were excluded. The data was obtained and analyzed by filling a specially designed proforma for each patient. RESULTS All 100 patients were between age ranges of 15-60 years (Mean age 37.5 years). Infection was present in 79% of cases. The commonest organisms isolated according to culture report were E. Coli (30%), Proteus (19%), Klebsiella (11%), Pseudomonas (7%), Staphylococcus aureus (3%) etc. The frequency of renal stone disease in patients with urinary tract infection was 18.98%. (12.6% in male and 6.3% in female). Mean age of patients with renal stones was 31.26 years and male to female ratio was 1.5:1. CONCLUSION Renal stone disease makes an important group among urinary stone diseases. Urinary tract infection with certain bacteria plays an important role in the synthesis of renal stones. A high incidence can be prevented by adopting a variety of simple conservative measures.
