A renal artery pseudoaneurysm is a rare but important complication that can occur after renal trauma, renal biopsy, percutaneous nephrostomy, percutaneous nephrolithotomy (PCNL), and partial nephrectomy. The incidence of this potentially life-threatening complication is less than 1%, but is likely to increase with the increasing popularity of endoscopic renal procedures. We present a case of a 30-year female who underwent right PCNL for a right renal pelvic stone. Two weeks later, she presented with massive hematuria...

PURPOSE: Although the worldwide percutaneous nephrolithotomy (PCNL) practice patterns determined via a survey sent to members of the Endourological Society have been published, differences in PCNL practice patterns among Latin American urologists based on endourological or lithiasis training have not been published. To determine the PCNL practice patterns among Latin American urologists with and without training in endourology. MATERIALS AND METHODS: The SurveyMonkey® web platform was used to develop a 27- item survey on PCNL for the treatment of renal stones, and the survey was sent via e-mail and other electronic media to 2000 urologists from 15 Latin American countries...

Interventional treatment of stones essentially consists of three treatment modalities. Extracorporeal shockwave lithotripsy (ESWL), in addition to uterorenoscopy (URS) and percutaneous nephrolitholapaxy (PCNL) is an essential treatment pillar and is the only noninvasive therapy option for the treatment of urinary stones. After a long period of ESWL being the leading choice in stone treatment, the number of SWL interventions diminished in recent years in favor of the other two treatment modalities (URS and PCNL)...

PURPOSE OF REVIEW: The role of PCNL and the expertise surrounding it has expanded in recent decades. Miniaturisation of equipment and instrument size has formed a part of this innovation. Although an increasing number of studies have been performed on miniaturised PCNL (Mi-PCNL) recently, a critical appraisal on these is lacking. We therefore conducted a systematic review of the literature to evaluate the efficacy, safety and feasibility of Mi-PCNL techniques (< 15 Fr). RECENT FINDINGS: A systematic review was conducted from 1990 to March 2017 on outcomes of Mi-PCNL [micro PCNL (m-PCNL) and ultra-mini PCNL (UMP)] in adult patients...

Objective: To choose appropriate size Amplatz sheath during percutaneous nephrolithotomy (PCNL) based on retrograde pyelogram. Material and methods: We performed standard PCNL in prone position in 20 patients. All these patients had placement of appropriate size of Amplatz sheath based on retrograde pyelogram images. All patients had nephrostomy tubes postoperatively. The preoperative and postoperative renal parameters, hemoglobin, mean operating time and mean hospitalisation stay were measured...

OBJECTIVES: To compare the distance between the colon and the trajectory of PCNL access both in prone and FFMS positions as measured on CT and to study the effect of age, gender, BMI, side and previous renal surgery as influencing factors. METHODS: In this prospective study, we included 367 patients scheduled for PCNL. All patients underwent low dose abdominal CT both in prone and FFMS positions. Patients<18 years and those with previous colonic surgery and/or renal congenital anomalies were excluded...

The objectives of the study are to compare the safety and efficacy of "all-seeing needle" optical puncture system micro-percutaneous nephrolithotomy (micro-PCNL) and flexible ureterorenoscopy (FURS) for the treatment of lower calyceal stones of ≤ 2 cm and to determine the advantages and disadvantages of each. 116 patients in total with lower calyceal stones of ≤ 2 cm were randomly divided into two equal groups, "all-seeing needle" optical puncture system micro-PCNL and FURS. In both groups, holmium laser was utilized for lithotripsy...

Purpose: Dexmedetomidine (DEX) has been reported to attenuate inflammation in rats. The present retrospective cohort study aimed to investigate whether intraoperative administration with DEX could reduce the incidence of postoperative systemic inflammatory response syndrome (SIRS) in patients following percutaneous nephrolithotomy (PCNL). Patients and methods: A total of 251 patients were included in the analysis. Among these patients, 175 received intravenous DEX infusion during the intraoperative period and 76 did not...

Objective: We propose a modification of the original Guy's Stone Score (GSS) to hold on 20 % of prognostic discrimination among groups which makes this score a more reliable resource for risk assessment in patients undergoing percutaneous nephrolithotomy (PCNL). Material and methods: Historical cohort of 126 patients undergoing PCNL from December 2010 to November 2014 was included in the survey. Every patient was classified according to the original GSS. For the new classification of Guy Stone Score (GSS-M) all of the subgroups included in the scale were analyzed individually and then ranked from better to worst according to the postoperative stone- free rates (SFRs)...

Ureteral stent placement is a common procedure in urologic practice. Forgotten, encrusted D/J stents represent a difficult problem for urologists. The major complications are infection, impaired renal function, migration, encrustation, stone formation and multiple fragmentation of stent. A consensus on the best therapeutic approach is still lacking. Here we present our experience with endoscopic management of this challenging problem and discuss the multimodal endourologic approaches for treating forgotten, encrusted ureteral stents...

INTRODUCTION: Upper pole access in percutaneous nephrolithotomy (PCNL) provides a straight tract to the ureter, resulting in easier placement of a guidewire to the ureter, good exposure of the pelvis, calices, and upper ureter, and comfortable manipulations. However, despite these benefits, upper pole access is usually avoided because of the risk of chest complications in both pediatric and adult patients. OBJECTIVE: We aimed to evaluate the safety and morbidity of single upper pole access in pediatric patients undergoing PCNL...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is a minimally invasive surgical procedure for renal calculi, and nephrostomy tubes lead to postoperative pain after PCNL. Regional techniques (e.g., epidural analgesia and peripheral blocks) and opioids are applied for postoperative pain treatment. The aim of this study was to compare effectiveness of ultrasound-guided paravertebral block (PVB) and tramadol on postoperative pain in patients who underwent PCNL. METHOD: Fifty-three patients were included in this prospective randomized study...

PURPOSE: This study aims to comparatively evaluate clinical outcomes of mini-PCNL and FURS for treating urinary tract calculi in a single session. METHODS: A systematic search using electronic databases was performed for studies comparing mini-PCNL and FURS for the treatment of urinary tract calculi. The primary outcome measurements were stone-free rates (SFRs) and complication rates for both techniques. Secondary outcome measurements were to compare patient demographics, operative duration, and inpatient stay...

Introduction: Success of any modality for stone disease needs to be evaluated in terms of Stone Free Rates (SFR), auxiliary procedures needed; complications and follow up. SFR in RIRS is subject to parameters like stone burden, location, number, hardness, composition; calyceal and ureter anatomy; use of ureteric access sheath (UAS); surgeon experience etc. Methods: The aim of this study is to evaluate the efficacy and safety of RIRS for managing upper tract stones...
