Objective: Miniaturized percutaneous nephrolithotomy (PCNL) reduces the risk of haemorrhagic complications, but limited field work represents a drawback. To obtain best outcomes, access size should be intraoperatively tailored. Our purpose is to describe indications and procedural steps Matryoshka technique report its clinical outcomes. Materials methods: We performed retrospective analysis dat...

PURPOSE To assess the safety and effectiveness of pure ultrasound-guided percutaneous nephrolithotomy. PATIENTS AND METHODS Three hundred fifty-seven patients were treated; 139 women and 218 men, with a mean age of 33.7 years (range 21-69 years) and a mean stone size of 33.5 mm in maximum diameter (range 20-52 mm). Stone locations were renal pelvis (174), lower calyx (68) or both (115) with m...

PURPOSE Nephrocalcinosis is commonly present in primary hyperparathyroidism, distal renal tubular acidosis and medullary sponge kidney disease. To our knowledge it has not been studied in patients with calcium phosphate stones who do not have systemic disease. MATERIALS AND METHODS We studied patients undergoing percutaneous nephrolithotomy who had calcium phosphate or calcium oxalate stones ...

Background: Majority of urologists prefer the usual prone position for percutaneous nephrolithotomy (PCNL) but due to various disadvantages PCNL, several alternative positions are being used. Aims and Objectives: The aim study was compare surgical outcomes PCNL performed using supine with those in position. Materials Methods: This a prospective observational study. After applying inclusion crit...

OBJECTIVE The objective was to demonstrate that percutaneous nephrolithotomy (PCNL) can be safely performed with a tubeless or totally tubeless drainage technique. INTRODUCTION Standard PCNL includes nephrostomy tube placement designed to drain the kidney and operative tract at the conclusion of the procedure. Modern technique trend is tubeless PCNL and totally tubeless PCNL, which are perfor...

Laparoscopically assisted percutaneous transperitoneal nephrolithotomy has been described to decrease the risk for the bowel injury.(3) There are serious limitations to PCNL. The Amplatz sheath is inserted dorsally near the iliac crest, which restricts free movement of the nephroscope and may damage retroperitoneal nerves. Alternatively, laparoscopic transperitoneal and retroperitoneal pyelolit...

Objective: To present our ‘methylene blue-guided retroperitoneoscopy technique’ that we apply in cases where extravasation develops for various reasons and is complicated as a result Percutaneous Nephrolithotomy surgery (PNL). Material Methods: A total of 36 patients, who underwent PNL with the blue at Bakirkoy Dr. Sadi Konuk Training Research Hospital between 2014 2020, were retrospectively ev...

OBJECTIVE The aim of this study was to systematically compare the perioperative outcomes of percutaneous nephrolithotomy in patients with or without previous ipsilateral open renal surgery (POS). DESIGN Systematic searches of the PubMed, Web of Science and Cochrane Library databases were used to identify relevant studies, and, following literature screening and data extraction, a meta-analysi...
