Ó Abstract: Squamous cell carcinoma, a rare malignancy of upper urinary tract accounts for 1.4% of all renal malignancies [1]. These tumours are mostly seen in the adults and less commonly in the pediatric age groups. Most of the cases present incidentally because they are masqueraded by pyonephrosis or hydonephrosis which occurs at an advanced stage of the disease and hence poor prognosis. A s...

We report our early experience with a new device for endoscopic stone disintegration: the Swiss lithoclast. This device was used to treat 200 patients with stones in kidney, ureter, and bladder. Its effectiveness was 100% when the stone could be approached irrespective of size or composition, and no complication was encountered. Prof. A. Kostakopoulos, Department of Urology, Sismanoglion Genera...

BACKGROUND Crystallographic composition of urinary tract stone varies in several chemical groups and determines the degree of fragmentation to extracorporeal shock wave lithotripsy (ESWL) which has been widely used for the treatment of renal and ureteral calculi. Visual prediction of stone composition by its morphology from plain radiograph may provide a simple method and clinical hint to decid...

Objectives Bleeding is the most common complication of percutaneous nephrolithotomy (PCNL). Injudicious transfusion is frequently performed in current practice, even though it is not always needed. This study aimed to identify the predictive factors of blood loss in the PCNL procedure and evaluate the perioperative transfusion practice. Methods A prospective study of PCNL was randomly performed...

Pleural effusions due to pleural injury following supracostal percutaneous nephrolithotomy (PCNL) occur in upwards of 15% of patients; however, these effusions are invariably diagnosed immediately postoperative or during the hospital stay. Herein, we report our initial experience with a delayed nephropleural fistula. A 52-year-old female underwent an uneventful supracostal right PCNL staghorn s...

INTRODUCTION The goal of percutaneous nephrolithotomy (PCNL) is to ensure complete stone clearance with minimal morbidity. The key to complete clearance is accurate technique, expertise and instrumentation. METHODS We systematically reviewed available reports that were identified using a PubMed/Medline search. The keywords used were 'PCNL' and 'advances in PCNL'. The findings were reviewed un...

Objectives: To examine the predictive effect of preoperative measurements stone volume (SV) against area (SA) on stone-free status (SF) following retrograde intrarenal surgery (RIRS). 
 Methods: We retrospectively examined medical records 68 RIRS patients with renal calculi who were eligible. Patients having non-contrast computed tomography ( NCCT ) before and subsequent to included, howev...

PURPOSE Percutaneous nephrolithotomy has high potential for morbidity or failure. There are limited data regarding risk factors for failure and to our knowledge no published reports of surgical outcomes in patients with prior failed attempts at percutaneous stone removal. MATERIALS AND METHODS We identified patients referred to 3 medical centers after prior failed attempts at percutaneous nep...
