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...

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...

Clinically insignificant residual fragments (CIRFs) are described as asymptomatic, noninfectious and nonobstructive stone fragments (≤4 mm) remaining in the urinary system after the last session of any intervention (ESWL, URS or PCNL) for urinary stones. Their insignificance is questionable since CIRFs could eventually become significant, as their presence may result in recurrent stone growth a...

Objectives:The aim of the present study was to assess the analgesic efficacy of IV ketamine injection inaddition to nephrostomy tract infiltration of ketamine – bupivacaine on postoperative pain relief after tubeless percutaneous nephrolithotomy (PCNL). Patients and Methods: Patients (n = 100), with renal stone who were candidates for PCNL were randomized to five groups with 20 cases in each: G...

Objective:
 To report our experience in percutaneous nephrolithotomy and endoscopic urinary tract stone surgery patients with diversion vesicostomy.
 Materials Methods:
 Data of 21 or vesicostomy who underwent for stones clinic between January 2008 2020 were retrospectively analyzed. Eight (38%) nephrolithotomy, 2 (9.5%) antegrade flexible ureteroscopy, 4 (19.0%) retrograde semi-...
