Incision of intrarenal sinus supplemented by a postrenal pole segmental incision for the removal of huge staghorn kidney calculus

Objective: To evaluate the surgical treatment method for huge staghorn calculus of kidney. Methods: The data of 45 cases treated with an incision of intrarenal sinus supplemented by a postrenal pole segmental incision for the removal of huge staghorn kidney caculus were analysed. Results: the average bleeding was 210 ml; Operation took 135 minutes (mean time); the biggest stone was 8.4 cm×4.8 cm×3.6 cm and in one case,the stones amounted to 105. All the cases were followed up by regular visits for 2 to 5 years. Renal function of all patients improved after operation. Postoperative examination with B ultrasonic and KUB+IVU revealed residual stone in 2 cases, the diameters being less than 0.8 cm. Conclusions: Incision of intrarenal sinus supplemented by a postrenal pole segmental incision for the removal of huge staghorn kidney caculus has the advantage of simple, safe, high single time clearance rate, few postoperative complications and preservation of renal function.
