Management of Solitary Renal Pelvic Stone: Laparoscopic Retroperitoneal Pyelolithotomy Versus Percutaneous Nephrolithotomy

Abstract Background and Purpose: Percutaneous nephrolithotomy (PCNL) is considered the main management option for large single renal pelvic stones; however, laparoscopic retroperitoneal pyelolithotomy (LRP) can be used as an alternative management procedure. We compare both procedures in the management of solitary large renal pelvic stones. Patients and Methods: Between June 2002 and July 2010, 105 patients with solitary large renal pelvic stones were selected and randomly divided into two groups; group 1 included 55 patients who were treated by LRP and group 2 included 50 patients who were treted by PCNL. 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 no statistically significant difference between LRP and PCNL regarding mean estimated blood loss (166.4±98.3 mL vs 178±102.4 mL), mean hospital stay (4.5±1.9 d, vs 4.4±1.4 d), mean time of postoperative analgesia (2.2±0.9 ...
