OBJECTIVES: To present the safety and efficacy of fluoroscopy-free ultrasound-guided PCNL for the treatment of renal calculi in pediatric patients of all ages. METHODS: 30 children with mean age of 5 years (6 months-12 years) underwent totally ultrasound-guided PCNL from March 2013 to August 2016. The pyelocalyceal system was punctured in prone position using only ultrasonography guidance, and the tract was dilated using a single shot dilation technique. No fluoroscopy was used during any of the stages of renal access...

Introduction: Percutaneous nephrolithotomy (PCNL) is traditionally performed with the patient in the prone position for large renal calculi. However, anesthetic limitations exist with the prone position. Similarly, the supine position is associated with poorer ergonomics due to the awkward downward position of the renal tract, a smaller window for percutaneous puncture, and a higher risk of anterior calyx puncture. This study aimed to demonstrate the feasibility and safety of lateral-PCNL in managing large renal calculi without the disadvantages of prone and supine positions...

Background The incidence of spina bifida (SB) is approx 1:1000, and risk of stone disease is substantially raised in SB. This is the unique published study of the outcome of patients with SB undergoing percutaneous nephrolithotomy (PCNL) compared to a neurologically intact historically matched control group at the same institution. Patients and Method A series of 96 PCNLs in 13 SB and 50 non-SB control patients was analysed. The following measurements were recorded: (1) Co-morbidities; (2) Pre-operative: (renal function, American Society of Anesthesiologists (ASA) score); (3) Intra-operative: (anaesthesia time, number of tracks, stone free rate) and (4) Post-operative: (sepsis, intensive therapy unit (ITU) and total length of stay, transfusion rate, stone composition, rate of stone disease-related nephrectomy)...

INTRODUCTION: Intrarenal inflammation has been implicated in the pathogenesis of nephrolithiasis, with prior work showing increased urine levels of IL-6, IL-8, and CCL-2 in stone patients. However, no studies have assessed for inflammation in the renal papillae. We sought to characterize novel papillary tip and urinary biomarkers in stone patients. METHODS: 92 patients with nephrolithiasis undergoing percutaneous nephrolithotomy were enrolled. Papillary tip biopsies, kidney urine, and bladder urine were collected, as well as voided urine from 8 healthy volunteers...

OBJECTIVE: Nephrostomy tubes (NT) inserted in emergency settings by interventional radiologists are frequently unsuitable for subsequent percutaneous nephrolithotomy (PCNL). We report a novel method of adjusting these NTs to be used as PCNL tracts and avoid renal re-puncture. PATIENTS AND METHODS: A retrospective search of 981 consecutive PCNLs performed in our institution between 2002-2017 identified all patients with preoperatively inserted NTs. The NTs unsuitable for PCNL were adjusted by a novel approach in which a 5-mm incision was made at the ideal puncture location (IPL) as indicated under fluoroscopic guidance...

Epidermoid cyst of the renal pelvis is exceptionally rare. The histogenetic mechanism has not been well characterized. Herein, we report a case of intrarenal epidermoid cyst in a 62-year-old woman who had undergone left nephrolithotomy for a staghorn calculus. She was being followed up for bilateral renal cysts when a complex mass was noted arising from the lower pole of the left kidney. Renal ultrasound showed a small left kidney with a solid vascular echogenic mass. A laparoscopic radical nephrectomy was performed...

Percutaneous nephrolithotomy has a success rate of 90%; however, its overall complication rate is approximately 83%, including urinary extravasation, bleeding necessitating transfusion, and postoperative fever. Septicemia, colonic and pleural injury are rare major complications. Neighboring organ injury, especially colonic injury, is frequently seen during tract dilatation procedure. In this study, we report a case of colonic lumbar hernia, which is a rare complication of percutaneous nephrolithotomy.
