The aim of the present study was to summarize the management of upper urinary tract calculi in crossed fused renal ectopia (CFRE). Two patients were retrospectively studied in Xiangya Hospital (Changsha, China) and all relevant literature published in English between 1996 and 2016 was reviewed. All patients, including those reported in the literature, were characterized by age, sex, manifestati...

Percutaneous nephrolithotomy (PCNL) is very popular and an efficient method as a gold standard in management of renal calculi. It is the first-choice method in management of renal calculi larger than 2 cm. Our patient underwent PCNL upon observing multiple renal calculi larger than 10 mm in a lower pole of the right kidney. Biopsy was performed during PNCL because morphology and endoscopic view...

OBJECTIVES To investigate the learning curve in the training of percutaneous nephrolithotomy (PCNL). METHODS A total of 104 PCNL cases were included in this evaluation to define the learning curve of a surgeon with no previous experience at performing solo PCNL. Two parameters of expertise were reviewed, namely the operation and fluoroscopic screening times. The operation time was calculated ...

PURPOSE Irrigation-induced increase in intrarenal pressure is of concern because it may cause infection due to increased pyelovenous and pyelolymphatic absorption. This study is the first to compare prospectively the absorbed fluid volumes during percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for stones larger than 2 cm. MATERIALS AND METHODS General anesthesia w...

Urolithiasis ranks second among urological diseases, after inflammatory processes, and first surgical interventions in hospitals. The problem of this disease treatment is a long-term rehabilitation disablement, which entails significant increase costs requires changes the tactics patients. Since its introduction until today, percutaneous nephrolithotomy (PCNL) standard for nephrolithiasis with ...

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 Percutaneous nephrolithotomy (PCNL) is the minimally invasive procedure of choice for removing renal stones larger than 2 cm. This study has aimed to identify the different variables that might influence decrease of hemoglobin during the surgery performed in supine position. MATERIAL AND METHODS A prospective, multicenter, observational study of supine PCNL, based on the Spanish Ass...

INTRODUCTION Percutaneous nephrolithotomy (PCNL) represents a safe and efficient procedure in the surgical management of renal lithiasis. Nevertheless, surgeons have to face specific complications during and after the procedure, hemorrhage being one of the most common. In most cases the injuries are self-limited and do not need a surgical intervention. Renal arteriography with selective angiogr...

PURPOSE To share the experience of the authors with the urological family in the world by the review of literature on supine percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS We have searched all the available databases, including PubMed or MEDLINE and Embase Biomedical Database to find any English articles related to supine PCNL from 1998 to 2010. Of 17 studies, 11 were case series ...

BACKGROUND AND PURPOSE Precise needle puncture of the kidney is a challenging and essential step for successful percutaneous nephrolithotomy (PCNL). Many devices and surgical techniques have been developed to easily achieve suitable renal access. This article presents a critical review to address the methodologies and techniques for conducting kidney targeting and the puncture step during PCNL....
