Ultra-mini-percutaneous nephrolithotomy in pediatric nephrolithiasis: Both low pressure and high efficiency

Re: Ultrasound‐guided micropercutaneous nephrolithotomy in pediatric patients with kidney stones

“…2 They had operated on 39 pediatric patients with the mean stone size of 20.4 mm, which is greater than the present study. They used a 9.5-Fr compact cystoscope as a nephroscope through a 12-Fr access sheath, and achieved 87% stone free rate without any great complication and blood transfusion.…”

“…The same team's previous study on the applicability and safety of ultra-mini percutaneous nephrolithotomy (PNL) in the treatment of pediatric kidney stones had better results than the present study. 2 They had operated on 39 pediatric patients with the mean stone size of 20.4 mm, which is greater than the present study. They used a 9.5-Fr compact cystoscope as a nephroscope through a 12-Fr access sheath, and achieved 87% stone free rate without any great complication and blood transfusion.…”

Clinical effectiveness in the diagnosis and acute management of pediatric nephrolithiasis

“…59 The advent of smaller equipment and instruments for newer techniques such as mini-PCNL, ultra-mini-PCNL, and micro-PCNL raise the possibility of fewer complications from traditional PCNL and lower risk of hemorrhage. 60 …”

How can the operation time be shortened by reducing the tract size?

“…Theoretically, a smaller tract causes less complication. Previous studies reported that reducing tract size could also reduce bleeding and thus reduce complications without affecting success rate [1].…”
