Outcomes of miniaturized percutaneous nephrolitotomy in infants: single centre experience

Abstract

Objectives:The present study was aim to evaluate the safety and efficacy of Mini-PNL to treat kidney stones in patients aged <3 years. This is the one of the largest series in the literature in this age group of patients.Material and methods:From May 2012 to April 2016, the medical records of 74 infant patients who underwent mini-PNL for renal stones were reviewed retrospectively. All infants were evaluated with the plain abdominal radiograph, urinary ultrasound, non-contrast computerized tomography and/or intravenous urogram. Pre-operative, intraoperative and post-operative data were analyzed.Results:A total of 74 infant (42 male, 32 female) with a mean age 21.5±8.2 (10-36) months were included in this study. The mean size of the stones was 22.0±5.9 (14-45) mm. A 17 Fr rigid pediatric nephroscope with a pneumatic intracorporeal lithotripsy were used through 20-22 Fr access sheath. The stone-free rate was 84.7% at 1 month after the operation. Mean operative time was 74.0 (40-140) min. Mean fluoroscopy screening time was as 4.3(3.1-8.6) min. Average hospitalization time was 3.8 (2-9) day. Auxiliary procedures were performed to 11(15.3%) patients (7 extracorporeal shock wave lithotripsy, 3 re- percutaneous nephrolitotomy, 1 retrograde intrarenal surgery). No major complication classified as Clavien IV-V observed in study group.Conclusions:Mini-PNL with pneumatic intracorporeal lithotripsy can be performed safely and effectively to manage kidney stones in infants with high stone free rate and low complications.

Outcomes of mini-percutaneous nephrolithotomy in children: a single centre experience

“…In another series of 135 children with an average age of 8.9 years, Salah et al reported a 98.5% SFR [10]. Pelit et al reported a SFR of 84.7% and 94.4% after single and additional sessions respectively [11]. In the present study, patients' records revealed that on the first postoperative day, complete stone-free state was achieved in 87.1% of cases (74/85).…”

Retrograde intrarenal surgery vs miniaturized percutaneous nephrolithotomy to treat lower pole renal stones 1.5-2.5 cm in diameter

“…Percutaneous nephrolithotomy (PCNL) is recommended for the treatment of larger stones, since it has a good success rate; however, the complication rates have been reported to be up to 25%[5]. With advancements in techniques and technologies, miniaturized PCNL (mini-PCNL), defined as a PCNL involving the use of smaller nephroscopes[6], can be performed effectively to manage kidney stones with high stone free rates and low complications[7]. The two surgical procedures have different advantages associated with the treatment of stones of different sizes affecting the urinary system[8-10].…”

A rapid and quantitative synthesis of xanthene derivatives using sulfonated graphitic carbon nitride under ball‐milling

“…The isolated products were fully characterized by FT-IR, 1 HNMR, and 13 CNMR spectroscopy. All the compounds had physical and spectroscopic data identical to those known xanthenes (Table 3) [41][42][43][44].…”
