Randomized Controlled Trial
Comparison of safety and efficacy of laparoscopic pyelolithotomy versus percutaneous nephrolithotomy in patients with renal pelvic stones: a randomized clinical trial.
A randomized clinical trial was designed to compare the efficacy, success rate and surgical complications of percutaneous nephrolithotomy (PCNL) and laparoscopic pyelolithotomy (LP). ⋯ PCNL remains the gold standard treatment for most large kidney stones, nevertheless, laparoscopic pyelolithotomy can be considered for selected cases especially in whom maximal preservation of renal function is necessary.

Comparative Study
Flexible ureterorenoscopy versus semirigid ureteroscopy for the treatment of proximal ureteral stones: a retrospective comparative analysis of 124 patients.
To investigate and compare the stone clearence and complication rates of flexible ureteroscopy (URS) with semirigid URS in patients having proximal ureteral stones. ⋯ Flexible URS is a favorable option for patients having proximal ureteral stones with higher stone free rate; on the other hand semirigid URS seems a less successful alternative for treatment of proximal ureteral stones.
