OBJECTIVE To compare the application time and the capacity of the nomograms to predict the success of Guy's Stone Score (GSS), S.T.O.N.E. Nephrolithometry (STONE) and Clinical Research Office of the Endourological Society nephrolithometric nomogram (CROES) of percutaneous nephrolithotomy (PCNL), evaluating the most efficient one for clinical use. MATERIALS AND METHODS We studied 48 patients w...

PURPOSE To compare efficacy and complications of spinal anesthesia versus general anesthesia in percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS In a prospective randomized study, 110 patients were randomly assigned into two groups for PCNL; group 1 (n = 52) underwent general anesthesia and group 2 (n = 58) received spinal anesthesia. In group 1, PCNL was performed using standard te...

INTRODUCTION To present the current practice patterns on percutaneous nephrolithotomy (PCNL) in a developing country. MATERIALS AND METHODS A survey was offered to Brazilian urologists during the II International Endourology Symposium held in Sao Paulo, in 2015. The first seven questions were related to demographic data while the 20 remaining were directed to urologists who performed PCNL. ...

Renal hemorrhage is one of the most common and worrisome complications of post-percutaneous nephrolithotomy (PCNL). This study aimed at evaluating the safety, effectiveness of utilization of the absorbable hemostatic gauze cover renal tract for hemorrhage of post-PCNL. The prospective study including 188 patients with upper urinary tract calculi was carried out in the department of Urology at L...

OBJECTIVE Tubeless percutaneous nephrolithotomy (PCNL) has become an option for treatment of renal stone disease, though no clearly defined algorithm exists for selection of patients suitable to tubeless PCNL. We investigated our experience with tubeless PCNL to evaluate its safety and efficacy for cases of complex renal calculi. PATIENTS AND METHODS Retrospective review of all tubeless PCNLs...

OBJECTIVE Preliminary study to assess the feasibility and safety of percutaneous nephrolithotomy (PCNL) as an ambulatory procedure. PATIENTS AND METHODS Between February 2011 and September 2012, 84 patients with renal calculi fulfilling the inclusion criteria were admitted to the Urology Department of Benha University Hospitals for PCNL. All patients were subjected to a full medical history, ...

background: percutaneous nephrolithotomy (pcnl) for renal calculi is less invasive treatment than open surgery. vascular complications of this procedure include hematoma, pseudoaneurysm and arteriovenous fistula of which pseudoaneurysm is usually symptomatic 24h after procedure. case report : we report a case of pseudoaneurysm, which was symptomatic within less than 24h following procedure and ...

PURPOSE To assess the efficacy and safety of percutaneous nephrolithotomy (PCNL) under the guidance of ultrasonography and fluoroscopy. MATERIALS AND METHODS We retrospectively analyzed 562 renal calculi patients (313 men and 249 women; mean age 46 years, ranged from 13 to 70 years) who underwent 582 PCNL from March 2004 to October 2011 in our department. RESULTS Of participants, 89.6% expe...

ARTICLE INFO ______________________________________________________________ ______________________ Main findings: We describe the use of a novel endoscopic approach in the management of unremitting gross hematuria following post-percutaneous nephrolithotomy (PCNL) in a 65-years-old male. This approach proved successful and cost-effective in managing haemorrhage post-PCNL when renal angiography ...

INTRODUCTION Supine percutaneous nephrolithotomy (PCNL) has become increasingly widespread during the last 2 decades. The aim of this study was to analyze the transition from prone to mainly supine PCNL in 2 endourologic centers. MATERIAL AND METHODS We retrospectively analyzed data on 214 consecutive supine PCNLs divided into the first (2011-2013) and last (2014-2016) 3 years of this study. ...
