The bivalve anatrophic nephrolithotomy

Purpose: In the era of lithotripsy, surgery gets a limited place in the man agement of renal stones. This study has for a goal to evaluate the practice , indications and results of anatrophic nephrolithotomy in the treatment of staghorn calculi. Patients and methods: Between: 1998 and 1999, six patients, mean age 37 yea rs, had complete staghorn calculi treated by anatrophic nephrolithotomy, an d two patients had a bilateral lithiasis. After lombar incision the kidney was incised on the convexity after pedicular control. In this way, we have extracted all lithiases. The nephrorrhaphy permits hemostasis and parenchym al reparation. A ureteral stent was placed. Results: The operatory follow-up was simple; hemostasis was controlled by f ast extraction of the lithiasis and nephrorrhaphy. The operating time was 7 0 minutes (40-110). The stone free rate was 100% without alteration of rena l function, patients with bilateral lithiasis have been operated twice time . Conclusion: The anatrophic nephrolithotomy is a safe technic without risk o f haemorrhage or renal function alteration. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
