BACKGROUND Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES The aim of this stu...

PURPOSE Although percutaneous nephrolithotomy (PCNL) has been accepted as a standard method for the management of large renal stones, the incidence of renal hemorrhage is relatively high. This study investigated the variables that affect bleeding during PCNL. MATERIALS AND METHODS The medical records of 370 patients who underwent PCNL by a single surgeon from January 2005 to December 2010 wer...

PURPOSE To evaluate the feasibility, safety and efficacy of one-shot dilation (OSD) in modified supine position percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS A total of 320 PCNL in a total of 291 patients were performed between October 2008 and July 2011. There were no specific exclusion criteria. Patients with kidney anomalies or solitary kidney, with history of renal surgery or...

BACKGROUND Limited studies have reported on radiation risks of increased ionizing radiation exposure to medical personnel in the urologic community. Fluoroscopy is readily used in many urologic surgical procedures. The aim of this study was to determine radiation exposure to all operating room personnel during percutaneous nephrolithotomy (PNL), commonly performed for large renal or complex sto...

BACKGROUND Percutaneous nephrolithotomy (PCNL) for large stone burden can be problematic in patients with significant risk of bleeding complications, specifically thrombocytopenia. This report demonstrates effective correction of two patients' thrombocytopenia, subsequently leading to removal of large stone burden through PCNL. CASE PRESENTATION We present two Middle Eastern patients who pres...

Extracorporeal shock wave lithotripsy was performed on 81 patients with urolithiasis (35 patients with ureteral stones, 25 patients with renal stones less than 2 cm in diameter, and 21 patients with renal stones more than 2 cm in diameter) at Kanbara Hospital from August to October, 1986. A 4 Fr catheter was placed transurethrally in the ureter up to the stone to identify the stone position and...

BACKGROUND Tubeless percutaneous nephrolithotomy is defined as PCNL without postoperative nephrostomy tubes. It is reported to reduce postoperative pain, hospital stay and recovery time. To date the procedure has been reserved for selected patients. OBJECTIVES To assess our initial experience in extending the implementation of tubeless PCNL without preoperative patient selection. METHODS Al...

The aim of the present study was to summarize the management of upper urinary tract calculi in crossed fused renal ectopia (CFRE). Two patients were retrospectively studied in Xiangya Hospital (Changsha, China) and all relevant literature published in English between 1996 and 2016 was reviewed. All patients, including those reported in the literature, were characterized by age, sex, manifestati...

Percutaneous nephrolithotomy (PCNL) has been the first-line treatment for renal staghorn calculi for many years. Several techniques have been described for percutaneous access and stone removal, but a multi-access approach is the mainstay of treatment. The main concern about PCNL is the resultant morbidity: Complications such as bleeding, parenchymal damage, and organ injury hindered the adopti...
