OBJECTIVE: Endoscopic procedures like percutaneous nephrolithotomy (PCNL) needs continuous irrigation for better vision and to wash away stone fragments and blood clots. Systemic absorption of irrigation fluids may lead to fluid overload and electrolyte disequilibrium. Renal failure patients are more prone to these electrolyte disturbances. We have evaluated the outcomes of normal saline as irrigation solution to be used in renal failure patient in comparison to distilled water. METHODS: Seventy-six patients with renal calculi were enrolled in this study between September, 2014, and December, 2015...

OBJECTIVE: While routine renal imaging following ureteroscopy for urinary calculi has been recommended to screen for asymptomatic "silent" obstruction, the rate of silent obstruction following percutaneous nephrolithotomy (PCNL) remains poorly defined, and no consensus recommendations exist on routine postoperative imaging. At our institution, we sought to assess the incidence of silent hydronephrosis (SH), as a screen for obstruction, following PCNL. METHODS: The records of all 162 patients who met study inclusion criteria were reviewed...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES: The aim of this study was to evaluate the clinical efficiency of MiniJFil® stenting associated with ESWL or second-line URS for the treatment of medium-to-large kidney stones...

INTRODUCTION: Literature suggests that the percutaneous punctures for PCNL must be performed at the papilla of the renal calyx and a puncture at the infundibulum or the direction of the pelvis is not advisable due to increased hemorrhagic risk. A prospective randomized study was conducted to investigate the safety in terms of blood loss of the infundibular approach for PCNL. MATERIALS AND METHODS: Patients with renal stones with a accumulative size of at least 2cm were randomly assigned to one of two parallel groups to undergo PCNL with either papillary (Group 1) or infundibular (Group 2) renal access...

Nephropleural fistulae are rare but serious thoracic complications of percutaneous nephrolithotomy (PCNL). Herein, we present the management of a 54-year-old female with a delayed presentation of nephropleural fistula. The role of serial thoracentesis as a safe, less invasive, less painful alternative to tube thoracostomy is highlighted. In select cases, this may represent an attractive management strategy for nephropleural fistula after PCNL.

Surgery in patients with congenital or acquired coagulation defects has always been challenging and requires special care with a multidisciplinary approach. Percutaneous nephrolithotomy (PCNL) is a standard procedure performed in patients with kidney stones. Although prone to bleeding more than most of the widely performed surgical procedures, there are not much data regarding PCNL in patients with bleeding disorders or coagulation defects. There are only case reports or series with a small number of patients for the patients with common coagulation defects, including hemophilias...

Significant literature has an impact on the reader. Reading the novella Heart of Darkness by Joseph Conrad as a young boy rose emotions comparable to those I felt when losing a patient after percutaneous nephrolithotomy (PCNL) as a grown up. The case of a 37-year-old woman with bilateral staghorn and a fatal outcome after PCNL is presented and alternatives are discussed.

BACKGROUND: Percutaneous nephrolithotomy (PCNL) has been adopted for pyelo-calyceal stones treatment in pediatric patients, starting from the 90's. Very recently, miniaturization of endoscopic instruments allowed less invasive procedures with low complication rate. We reviewed our experience on upper tract stone treatment utilizing two different percutaneous accesses, focusing on the recent new miniaturized devices offered for pediatric renal stones. METHODS: Patients presenting upper tract urinary stones observed from January 2011 to December 2015 and treated by percutaneous renal access were prospectively evaluated: age, sex, metabolic issues, associated abnormalities, treatment modalities, hospital stay and complication rate were recorded in a specific database...

The aim of this study was to compare the accuracy of the CROES nephrolithometric nomogram and S.T.O.N.E. scoring system in predicting PCNL outcomes in terms of stone-free rate, estimated blood loss (EBL), operative time (OR), length of hospital stay (LOS), and complications. Patients who underwent PCNL for renal stones between May 2012 and January 2015 were analyzed retrospectively. The patients' demographic characteristics and operational features were recorded prospectively in all patients postoperatively...

The incidence of pediatric nephrolithiasis has risen over the past few decades leading to a growing public health burden. Children and adolescents represent a unique patient population secondary to their higher risks from radiation exposure as compared to adults, high risk of recurrence, and longer follow up time given their longer life expectancies. Ultrasound imaging is the first-line modality for diagnosing suspected nephrolithiasis in children. Although data is limited, the best evidence based medicine supports the use of alpha-blockers as first-line MET in children, especially when stones are small and in a more distal ureteral location...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is the preferred treatment of choice for renal calculi. PCNL has evolved remarkably since the eighties when it was first described. APPROACH: Approach might be by either supine or prone and the access is made with the help of either fluoroscopy or ultrasound. Recently endoscopy guided puncture has also been described. MINIATURIZATION: Traditionally the tract size for PCNL used to be 30Fr. Even though the stone clearance rate was good there were complications such as bleeding With the advent of excellent optics and advances in stone fragmentation the tract size has reduced to a great extent which has reduced the complications without compromising the stone clearance...

Stones in solitary kidney represent a management dilemma for the endourologist. The advantage of bilateral fully functioning kidneys is not present. Therefore, any insult to either the solitary kidney itself or drainage system can lead to significant morbidity. Key clinical objectives include maximum preservation of existing renal function, high stone clearance and minimising post procedure complications. To date there exists no Level 1 evidence on this subject. This systematic review serves to evaluate the safety and efficacy of percutaneous nephrolithomy (PCNL) for patients (adults only) with stones in a solitary kidney...

INTRODUCTION: Between 5 and 10% of patients undergoing percutaneous nephrolithotomy (PCNL) develop postoperative sepsis 1, 2. Strategies to prevent infectious complications are based on information provided by preoperative midstream urine cultures (PMUC). The aim of this study is to evaluate the concordance of the microbiologic findings of PMUC, cultures of the renal stone (RSC) and urine obtained directly from the renal pelvis (RPUC) in patients undergoing PCNL. MATERIALS AND METHODS: This is a multicenter prospective study...

Technical innovations in all aspects of percutaneous nephrolithotomy have changed the field considerably. The current review is aimed at reporting on the most recent advancements in the field of percutaneous nephrolithotomy. Improvements in CT imaging and the possibility of 3D rendering have dethroned the intravenous pyelogram as gold standard for pre-operative imaging. Where gaining access in the lower pole in prone position with telescopic metal dilators, placing a 30F tract used to be standard, the plethora of alternatives provides the trained surgeon with a large armamentarium to tackle any obstacle...
