Abstract :

Introduction:

To report our experience with the treatment of renal matrix stones, an infrequent form of urinary calculi whose diagnosis and treatment are often difficult.

Materials and Methods:

Retrospective & prospective study, June 2011 – May 2018, PCNL done for 1400 Pts. 32 for matrix calculi, Pre–procedure investigations included–CECT KUB,Urine Routine and culture. PCNL procedure was performed in all, Post op follow up was done.

Results:

Incidence in our population was 2.2%. Mean age was 44.3 years. Flank pain was commonest mode of presentation. Most common predisposing factors being previous urolithiasis. A plain X–ray showed a small radio–opaque calculus in 16 patients. Non–contrast computed tomography diagnosed calculi 32 patients with mean Hounsfield units being 550HU. The mean stone size was 2.2cms.The mean hospital stay was 4.3 days and decrease in haemoglobin was 0.89 g/dL. One patient developed sepsis. Of 24 stones analysed, 6 were composed entirely of proteins and the remaining 18 had crystalline components. At a mean follow–up of 12.2 months, no patients had recurrence of stones.

Conclusion:

Percutaneous lithotripsy has been confirmed as the first option for matrix stones.
