Summary: | Objectives : The objective of this study was to determine the efficacy (defined by stone-free rates) and safety of percutaneous nephrolithotomy (PNL) in the treatment of medium sized (1-2 cm) symptomatic lower pole renal calculi, and establishment of the short-term morbidity.
Methods : We performed a retrospective analysis of 60 evaluable patients who had undergone PNL for 1 to 2 cm diameter lower-pole (LP) stones between November 2006 to March 2009 and compared these results with other treatment modalities in published literature.
Results : In all cases, stones were located in the lower calix. Thirty-six procedures were performed on the left side, and 24 were performed on the right side. The mean time to access the collecting system was 20.4 minutes (range 8-70 min) and mean operative time was 62.2 minutes (range 13-155 min). Abdominal radiography performed on postoperative day 1 demonstrated a stone free status in 56 (93.3%) patients. However, 4 patients (6.7%) required ancillary procedures (secondary PNL in 1, retrograde intrarenal surgery in 1, and SWL in 2). After this secondary procedures a complete stone-free status was achieved in 98.3% of patients. The morbidity of patients undergoing PNL at our hospital was minimal, with a mean hospital stay of 3.7 days.
Conclusions : We demonstrated that, PNL is a safe and effective method for medium sized (1 to 2 cm) lower pole renal calculi and percutaneous removal should be considered the primary approach for lower pole stones greater than 10 mm. |
