Ultra-Mini-Percutaneous Nephrolithotomy in Flank-Free Modified Supine Position Prone Position in Treatment of Pediatric Renal Pelvic and Lower Caliceal Stones.

To report the safety and efficacy of ultra-mini-percutaneous nephrolithotomy (UMPCNL) in flank-free modified supine (FFMS) and prone positions in management of pediatric renal calculi. This prospective randomized study included 55 pediatric patients with symptomatic renal stones and suitable for UMPCNL. They were randomized into two groups.

Immediate versus delayed shockwave lithotripsy for inaccessible stones after uncomplicated percutaneous nephrolithotomy.

Objective: To evaluate the efficacy and safety of immediate versus delayed shockwave lithotripsy (SWL) for inaccessible stones after uncomplicated percutaneous nephrolithotomy (PCNL).

Patients And Methods: Between December 2011 and June 2014, patients with residual inaccessible stones after uncomplicated PCNL were prospectively randomised into two treatment groups; Group I, immediate SWL and Group II, delayed SWL at 1 week after PCNL. Patients with residual stones of ⩾1.

Flank-free Modified Supine Percutaneous Nephrolithotomy in Pediatric Age Group.

Objective: To evaluate the safety and efficacy of pediatric percutaneous nephrolithotomy (PCNL) in the flank-free modified supine position (FFMSP). PCNL in the supine position is increasingly and successfully used in pediatric age group. Different modifications of supine positions have been described; however, the best supine position is not well established and remains a matter of debate.
