Background: The aim of the study is to investigate whether laparoscopic pyelolithotomy (LPL) could be used to manage large renal pelvic stones, generally considered excellent indications for percutaneous nephrolithotomy (PNL).Methods: This study was performed from May 2009 to March 2012 at Al-Azhar University Hospitals (Assiut and Cairo), Egypt. It included two groups of patients with large renal pelvic stones; only patients with stones 2.5 cm2 or greater were included. Group1 included 40 patients treated by PNL and Group 2 included 10 patients treated by LPL. The differences between the two procedures were compared and analyzed.Results: There was no difference between the two groups regarding patient demographics and stone size. There was a statistically significant difference between the groups regarding mean estimated blood loss (65 ± 12.25 [range: 52.75- 77.25] vs. 180 ± 20.74 [range: 159.26- 200.74] mL, p ≤ 0001), mean hospital stay (2.3 ±0.64 [range: 1.66- 2.94] vs. 3.7 ± 1.4 [range: 2.3- 5.1] days, p ≤ 0.006), rate of postoperative blood transfusion (0% vs. 4.8%,p ≤ 0.0024), and stone-free rate (80% vs. 78.6%, p ≤ 0.23). The mean operative time was significantly longer in Group 2 (LPL) (131 ± 22.11 [range: 108.89-153.11) vs. 51.19 ± 24.39 [range: 26.8-75.58] min, p ≤ 0001), respectively.Conclusion: Although PNL is the standard treatment in most cases of renal pelvic stones, LPL is another feasible surgical technique for patients with large renal pelvic stones.
