OBJECTIVE This review focuses on a step-by-step approach to percutaneous nephrolithotomy (PNL) and its complications and management. METHODS Based on institutional and personal experience with >1000 patients treated by PNL, we reviewed the literature (Pubmed search) focusing on technique, type, and incidence of complications of the procedure. RESULTS Complications during or after PNL may be...

The surgical management of pediatric stone disease has evolved significantly over the last three decades. Prior to the introduction of shockwave lithotripsy (SWL) in the 1980s, open lithotomy was the lone therapy for children with upper tract calculi. Since then, SWL has been the procedure of choice in most pediatric centers for children with large renal calculi. While other therapies such as p...

Delayed hemorrhage following percutaneous nephrolithotomy (PCNL) is secondary to pseudoaneurysm or arteriovenous fistula, which happens in less than 1% of PCNLs. Predisposing factors are: medial puncture instead of posterolateral puncture, arteriosclerosis, and hypertension. Definite diagnosis is made by angiography and embolization, as a definite treatment, can be done through the same angiogr...

OBJECTIVE To investigate the effect of thoracic paravertebral block (PVB) on pain control and morphine consumption in percutaneous nephrolithotomy operations. SUBJECTS AND METHODS This randomized controlled clinical study was performed on 60 American Society of Anesthesiologists (ASA) I-II patients between the ages of 18 and 60 years who underwent percutaneous nephrolithotomy with approval of...

PURPOSE To compare the efficacy of extracorporeal shock wave lithotripsy in managing residual stones after ureterolithotripsy and mini-percutaneous nephrolithotomy. MATERIALS AND METHODS A retrospective study was carried out of 71 patients with proximal urinary tract stones (greater than 10 mm) who underwent ureterolithotripsy or mini-percutaneous nephrolithotomy at a single institution from ...

A 51-year-old man presented with fever, chills, and significant weight loss of 6 months’ duration. Three months earlier, the patient had undergone percutaneous nephrolithotomy for right-sided kidney calculus. Computed tomography revealed an 11.6 × 14.9 × 14.9-cm encapsulated multiseptated hypodense mass with enhancing walls and septa and areas of fat density and air in the right suprarenal regi...

OBJECTIVE To assess the efficacy and safety of a "mini-perc" technique of percutaneous nephrolithotomy using a 14-Fr peel-away sheath for the removal of pyelocaliceal stones, and to determine appropriate inclusion criteria. MATERIALS AND METHODS From July 1999 to June 2002, the medical records and radiographic images of 72 patients who underwent the "mini-perc" technique of percutaneous nephr...

BACKGROUND Percutaneous nephrolithotomy is a minimally invasive intervention for renal stone disease. Complications, which are rare and usually presented as case reports, are diversified as the utilization of the procedure is expanded. The procedure causes less blood loss and less morbidity when compared to open surgical procedures. Yet, there are some reports involving severe bleeding and rele...

*E-mail: [email protected] We report a rare case of an ectopically placed ureteral stent, which was acceptable and functional. obstructing 8 × 15-mm proximal right-sided ureteral calculus. There were also multiple nonobstructing renal calculi on the left side. An antegrade ureteral stent was placed to relieve his infected and obstructed right kidney. During stent placement, the interventional ra...
