PURPOSE To compare the stone clearance rate, efficiency quotient (EQ), and early complications of shock wave lithotripsy (SWL) and percutaneous nephrolithotomy (PCNL) for solitary lower-pole renal stones measuring 15 to 20 mm. MATERIALS AND METHODS This was a retrospective matched-pair analysis of 142 patients (78 in the SWL and 64 in the PCNL group). Preoperative imaging was done by use of n...

OBJECTIVE To investigate the feasibility of thoracic paravertebral block (TPVB) for percutaneous nephrolithotomy (PCNL) in comparison with epidural anesthesia (EA) combined with moderate sedation. SUBJECTS AND METHODS One hundred American Society of Anesthesiologists (ASA) I-II adult patients scheduled for first-stage unilateral PCNL were randomly assigned to receive either TPVB or EA. All pa...

OBJECTIVE The objective of this study is to evaluate our methods for management of renal caliceal diverticular stones (CDS). MATERIALS AND METHODS We conducted a retrospective study from January 2005 to July 2015 and included patients who were treated for renal CDS. Patients were evaluated for treatment modality, puncture site (in case percutaneous nephrolithotomy [PCNL] attempted), operative...

Percutaneous nephrolithotomy (PCNL) is the treatment of choice for patients with renal calculi ≥ 2 cm as well as larger lower pole calculi [1,2]. The armamentarium of specialized rigid and flexible nephroscopes and powerful lithotripters allow for greater stone-free rates in the treatment of patients with large stone burdens [3]. However, in comparison to shockwave lithotripsy and ureteroscopy,...

BACKGROUND AND PURPOSE Percutaneous nephrolithotomy (PCNL) in elderly patients is challenging due to the high prevalence of comorbidity and single kidney. We compared the results and complications of patients who were submitted to PCNL according to age (higher than and lower than 65 years old). MATERIALS AND METHODS A total of 61 patients aged more than 65 years old (group I) and 385 patients...

BACKGROUND To compare the treatment outcomes between percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for the management of stones larger than 2 cm in patients with solitary kidney. METHODS One hundred sixteen patients with a solitary kidney who underwent RIRS (n = 56) or PCNL (n = 60) for large renal stones (>2 cm) between Jan 2010 and Nov 2015 have been considere...

Background: Colonic injury represents a rare complication of percutaneous nephrolithotomy (PCNL). Injury of the small bowel is very rare, with only anecdotal case reports in the literature. We report here a rare PCNL complication of jejunal perforation without concomitant colonic injury. Case Presentation: A 45-year-old male underwent PCNL for multiple left kidney stones. At the beginning of th...

Sixty eight consecutive cases of percutaneous renal surgery, percutaneous nephrolithotripsy (PCNL), were performed on 64 patients (male-41, female-23) at the Subang Jaya Medical Centre from April 1988 to July 1989. All the cases were done as a one stage procedure. Fifty eight stones were large renal or staghorn and ten were ureteric. Thirty cases (41%) were stone free after PCNL alone. Thirty e...

INTRODUCTION In 1941 Rupel and Brown used a rigid cystoscope to extract the residual stones through a drain tract following open surgery.(1) That was the beginning idea of endoscopic renal surgery. L shaped endoscopes were used for visualizing calyceal stones during open procedures. The percutaneous nephrostomy was described by Goodwin in 1955 as a temporary solution for obstruction secondary h...
