OBJECTIVES: To describe the technique of the minimal access percutaneous nephrolithectomy, miniperc, and to analyze the results obtained with this treatment in adult patients. METHODS: We performed 42 minipercs between august 2002 and December 2003. Mean patient age was 48 years (19-62). The procedure was undertaken using a 14Fr Amplatz sheath. Stone size varied from 1.5-3.5 cm in longest diameter (1.5-7 cm²). Lithofragmentation was performed by pneumatic lithotripsy. RESULTS: Average procedure time was 75.2 min. (range from 60 to 120). All patients were discharged within 24 hours. Only three patients (7.1%) have a hematocrit descent over 2 points. No nephrostomy tube was left for the postoperative time. 95.2% of the patients were stone free 1 month after surgery. CONCLUSIONS: Our results make us consider the minimal access percutaneous nephrolithectomy (Miniperc) a minimal option for the elimination of renal stones, with low morbidity, diminishment of the hospital stays, very low analgesic demand, and no transfusion requirements.
