PURPOSE Aspirin is often stopped prior to percutaneous nephrolithotomy due to concern about the surgical bleeding risk. There is evidence that discontinuing aspirin perioperatively increases thromboembolic events and continuing it may be safe. We assessed the effect of continuing low dose aspirin through percutaneous nephrolithotomy and its effect on surgical and safety outcomes. MATERIALS AN...

OBJECTIVES To evaluate the success of ultrasonography directed renal access in entering the target calyx from proper entry site and in the direction of renal pelvis during percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS PCNL cases who were operated on by one fellow from May-June 2014 were included in this study. A vertically placed ultrasound probe on the patient flank in prone pos...

INTRODUCTION Several therapeutic methods are used in the management of lower pole caliceal calculi. This survey has been conducted to evaluate the safety and efficacy of percutaneous nephrolithotomy in the management of lower pole calculi. MATERIALS AND METHODS Fifty-five patients, 43 males and 12 females with a mean age of 41.5 (range 11 to 75) years, who had suffered from lower pole calicea...

Two morbidly obese males weighing 159 kg and 184 kg underwent percutaneous nephrolithotomy (PCNL) for large, symptomatic renal stones. To avoid anesthetic complications and cardiorespiratory compromise in the prone position, the procedures were performed under IV sedation with local anesthesia. The risks of PCNL in this patient population are reviewed, and the technique employed to mitigate the...

PURPOSE The traditional prone positioning of percutaneous nephrolithotomy (PCNL) is associated with various anesthetic and logistic difficulties. We aimed to compare the surgical outcomes of PCNLs performed using our modified supine position with those performed in the standard prone position. MATERIALS AND METHODS A prospective group of 236 renal units (224 patients) undergoing PCNL were inc...

Percutaneous nephrolithotomy (PCNL) is the standard of care for the management of large renal stone burdens. Residual stones after PCNL may be cleared with a second-look nephroscopy. Determining whether a patient should undergo a second-look procedure is based on both the intraoperative findings and the post-operative imaging. Aggressive intraoperative flexible nephroscopy, may reduce the need ...

BACKGROUND In this study, we aimed to explore the effect of ultrasound-guided percutaneous nephrolithotomy (UGPN) for the treatment in patients with kidney stones (KS). METHODS We randomly assigned 86 patients with KS to a UGPN group or a control group, each group comprising 43 patients. Patients from the UGPN group underwent UGPN whereas those from control group underwent fluoroscopic-guided...

Percutaneous nephrolithotomy has revolutionized the ability of the urologist to remove large burdens of renal stones over the last 15 years. In the United States, it has largely replaced open stone surgery for the treatment of large sized stones. One of the key factors in optimizing outcomes for this procedure is accurate percutaneous renal access. The guiding principles for effective renal acc...

Urolithiasis is a worldwide problem in the general population, due to its high prevalence and frequency of recurrence. Since the first successful stone extraction through a nephrostomy in 1976, percutaneous nephrolithotomy (PCNL) has become the preferred procedure especially for treatment of large, complex staghorn calculi. Of the minimally invasive treatment strategies, the PCNL procedure is s...
