PURPOSE To evaluate the efficiency, accuracy, and safety of robotic percutaneous access to the kidney (PAKY) for percutaneous nephrolithotomy in comparison with conventional manual techniques. MATERIALS AND METHODS We compared the intraoperative access variables (number of access attempts, time to successful access, estimated blood loss, complications) of 23 patients who underwent robotic PAK...

Percutaneous nephrolithotomy (PCNL) is recommended procedure for stones greater than 2 cm This being used commonly by all urologists worldwide. With increasing using of imaging studies, the incidence large staghorn calculus has been consistently decreasing because most are detected while they still small. In this case report we presenting a size 6.7×5.2 which was completely cleared PCNL with ne...

Percutaneous nephrolithotomy (PCNL), a minimally invasive method for removal of renal calculi, was initially started in the 1950s but gained popularity about two decades later and has now become standard practice for management. There has been an immense improvement in technique and various guidelines have been established for treatment of renal stones. However, it has its own share of complica...

PURPOSE To assess safety and efficacy of supine percutaneous nephrolithotomy in patients for whom prone position or general anesthesia is contraindicated or not preferable due to associated comorbidities, overweight or ipsilateral upper ureteric calculi. MATERIALS AND METHODS Fifty two patients (37 males and 15 females, mean age 33 ± 10.2 years) were included in this study. Supine position wa...

INTRODUCTION We previously reported on the effectiveness of ureteroscopy-assisted retrograde nephrostomy during percutaneous nephrolithotomy and report two cases of lower calyx calculi in horseshoe kidney that were successfully treated with ureteroscopy-assisted retrograde nephrostomy. During the ureteroscopy-assisted retrograde nephrostomy procedure, a ureteroscope is advanced in the desired c...

Introduction: The present study aimed to assess the efficacy and safety of percutaneous nephrolithotomy (PCNL) in elderly patients. Materials and Methods: We retrospectively reviewed 50 PCNLs performed in the elderly patients (age > 65 years) carried out in our clinic from 2001 through 2007 and compared those with 248 PCNLs performed in younger patients (age < 40 years) during the same period. ...

Purpose. The duration of urine leakage following the removal of the nephrostomy tube after percutaneous nephrolithotomy (PCNL) shows significant variations depending on the techniques used. We aimed to assess the factors likely to influence the duration of urine leakage. Material and Methods. In total, 103 patients who underwent PCNL were reviewed retrospectively. DUL was evaluated regarding pa...

Objective. To predict the success rate and complications following percutaneous nephrolithotomy via the upper pole using the Guy's Stone Score (GSS) based on the findings of a preoperative intravenous pyelogram (IVP). Patients and Methods. Two hundred and twenty-seven renal operations, which were carried out using PCNL via the upper pole, were classified according to the GSS assigned. Any compl...

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 ...
