The chemical compositions of urinary calculus

All of calculus stones were complex in this study. CaOx and CaP were the main components with highest frequency in urolithiasis patients. The composition of calcium cation is of inverse proportion with magnesium cation

Selection of incision in the treatment of kidney staghorn calculi

Though Extracorporeal shock wave lithotrysy (Eswl) combined with Percutaneous nephrostolithotomy (PNL) have revolutioned the treatment of kidkey stones, open surgical treatment of staghorn calcului is reasonable in certain circumstances. Of 169 kidney stones, 72 staghorn calculi (19.51 per cent) were treated by surgery. Age of patients are from 21 to 73 (29 males and 43 females). Left renal culculi: 31 and right renal calculi 41; procedures included: pyelolithotone (5); pyelolithotomy + limited nephrolithotomy (13); radial nephrolithotomy (2); Turner Warwick (5); Resnixk (25); Bivalve (3); extended nephorolithotomy 97); partial nephrectomy (3); nephrectomy (9). The most common reasons for prefering an incision were size of calculi, anatomy and modification of renal parenchyma

Treatment of intrasinus renal calculus by Turner Warwick surgery

31 cases of intrasinus renal calculus were opened surgically by Turner Warwick technique in Urology department of Hospital N0 103, including: 13 males and 18 females. Renal function was determined with serum blood urea nitrogen, creatinine and clearance. There was no significant difference in BUN and clearance preoperatively and postoperatively. There was significant increase in serum creatinine postoperatively.
