Mini-percutaneous nephrolithotomy in treatment of renal staghorn calculus

Objective To evaluate the feasibility and complication of mini-percutaneous nephrolithotomy in the treatment of renal staghorn calculus.Methods From April 2002-Oct 2004, the clinical data were retrospectively analysed in 32 cases of renal staghorn calculus. Results They were treated with one-stage operations in 18 cases, two-stage in 14 cases,of which single channel was used in 28 cases,two- channel in 3 and three- channel in 1. The stone-free rate reached 90.6%. The average operative duration was 2.3 h.The duration of hospitalization was 4-6 days with an average of 4.6 days in one-stage stone-free clearance patients.Only one patient was complicated with severe bleeding on the sixth day after the procedure, and was successfully treated with super-selective arterial embolization. Conclusion MPCNL has definite efficacy in the treatment of renal staghorn calculus with less suffering and shorter recovery time.
