FREE STONE FREQUENCY AFTER PERCUTANEOUS NEPHROSTOLITHOMI WITH FLEXIBLE NEPHROSCOPE
Abstract
Introduction: The prevalence of urinary stones is 2-3"10.Therefore well treatment of the stones is vwre important PCNL is the new method sor excluding the stones from kidney with minimal pain, convalescence, convalescence, complications and cost. The flexible nephroscope role is evaluated in this study.
Methods: All 60 patients that PCNL was done on them in Al-Zahra hospital 0 Esfahan From Farvardin to Dei 1378 are evaluated in this study. At firt pyelocalyceal system is checked with rigid nephroscope and stones are excluded. Then pyelocalyceal system is checked with flexible nephroscope and if the residual stone presents, it will be excluded.
Results: With flexible nephroscope stone excluded from kidney in 45% in PCNL patients. Stone free rate was 75%. The mean of the stone surface was 668±415mm2. The stones were staghorn or multiple in 90% of patients. Complications were 6.7% of case containing: fever and late hematuria. The hospitalization time was 2.7±1 day. Sequence percentage of upper, middle, lower calyces that been seen by rigid nephroscope were in srder: 31.7%, 8.8%, 86.7% and by flexible nephroscope were in order: 95%, 70.2%, 95%.
Discussion: Flexible nephroscope considerably increases stone free rate in PCNL patients and to see the upper and middle calyces significantly helps the surgen. The use of flexible nephroscope is recommended for all PCNL patients all over the country.
